Xml1 Sample

Xml2 Sample

This sample demonstrates creating custom XmlDocument and XslTransform objects and passing them into the Xml server control to be displayed. You can also pass a preloaded XmlDocument to the Xml server control's Document property. Additionally, you can pass a preloaded XslTransform to the control's Transform property.

Namespaces used in this sample:

System; System.Xml; System.Xml.Xsl

Classes used in this sample:

Xml; XmlDocument; Page; XslTransform; Import; Path; EventArgs; Object

DataGrid8 Sample

This sample shows how to implement simple sorting in DataGrid.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; DataColumn; DataView; Font; String; DataTable; Object; Header; Style; Table; EventArgs; Page; CommandEventArgs; DataRow; Import; DataGridSortCommandEventArgs

DataGrid1 Sample

This sample demonstrates using the DataGrid server control to display tabular data and optionally support selecting, sorting, paging, and editing the data. By default, DataGrid generates a BoundColumn for each field in the data source; the AutoGenerateColumns property is set to true.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; DataColumn; Font; DataTable; Table; DataView; String; Style; DataRow; Page; Header; EventArgs; Import; Object

DataGrid9 Sample

This sample creates an Outlook-style sort button using a TemplateColumn. Note that the button must also specify the "sort" CommandName. Additionally, it must pass the field by which to sort as a CommandArgument.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; Header; DataColumn; String; Button; Font; DataView; Table; DataTable; Image; Object; Style; TemplateColumn; BoundColumn; EventArgs; Page; CommandEventArgs; Label; Import; DataBinder; DataGridSortCommandEventArgs; Binder; Url; ImageButton; Container; DataRow

DataGrid6 Sample

This sample demonstrates using the EditCommandColumn. The EditCommandColumn is a special column type that supports in-place editing of the data in one row in the grid. EditCommandColumn interacts with another property of the grid, EditItemIndex. By default, the value of EditItemIndex is -1, meaning none of the rows (items) in the grid is being edited. If EditItemIndex is -1, an Edit button is displayed in the EditCommandColumn for each row in the grid.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; Header; Table; Object; DataTable; EventArgs; String; CommandEventArgs; Style; DataGridCommandEventArgs; DataColumn; BoundColumn; Font; TextBox; DataView; DataRow; Control; Page; Import; EditCommandColumn

DataGrid3 Sample

This sample demonstrates passing the value of the IntegerValue data field as an argument in the URL to another page. The StringValue data field is used as the display text of the hyperlink. A HyperLinkColumn presents the bound data in HyperLink controls. This is typically used to navigate from an item in the grid to a details view on another page.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; String; Header; DataColumn; BoundColumn; Form; DataTable; HyperLink; Object; Style; Font; EventArgs; Page; DataView; HyperLinkColumn; Url; Table; Import; DataRow

System.Data; System

Classes used in this sample:

DataGrid; String; Header; DataColumn; BoundColumn; Label; Button; Object; Style; Font; EventArgs; DataTable; DataView; Table; Import; Page; DataRow; Form

DataGrid5 Sample

This sample demonstrates using two TemplateColumns. With a TemplateColumn you completely control which controls are rendered in the column, and which data fields are bound to the controls. The first column renders two LinkButton controls. These bubble commands to the grid's ItemCommand, just as a ButtonColumn does. The last column binds the true or false value to a read-only CheckBox.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; Table; DataColumn; Header; Button; DataTable; Font; TemplateColumn; String; DataView; Style; TableCell; LinkButton; EventArgs; BoundColumn; DataRow; CommandEventArgs; Object; Import; DataBinder; Page; Binder; Form; Container; DataGridCommandEventArgs; Assembly; CheckBox

DataGrid4 Sample

This sample shows how a ButtonColumn is used to bubble a user command from within a row to an event handler on the grid. In this sample, the "Add To Cart" and "Remove From Cart" commands cause the item from the corresponding row to be added to or removed from a simple shopping cart.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; Table; DataColumn; Header; DataTable; Button; Font; DataView; String; Style; TableCell; ButtonColumn; BoundColumn; Object; DataRow; EventArgs; Import; Page; CommandEventArgs; Form; LinkButton; DataGridCommandEventArgs; Assembly

DataGrid13 Sample

This sample demonstrates using TemplateColumns to precisely control how the data is edited.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataGrid; TemplateColumn; Header; CheckBox; TextBox; DataRow; Font; DataTable; String; DataColumn; Container; Table; Page; Object; GC; EventArgs; Form; DataRowView; Label; Control; BoundColumn; Style; DataView; LinkButton; Button; Binder; GridItem; DataGridItem; Import; DataBinder

DataList2 Sample

This sample illustrates using a SelectedItemTemplate property in a DataList to customize the content and appearance of the selected item. The SelectedItemTemplate is controlled by the SelectedIndex property. By default the value of SelectedIndex is -1, meaning none of the items in the list is selected. When SelectedIndex is set to a particular item, that item is displayed using the SelectedItemTemplate.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataList; String; DataBinder; Binder; Container; Header; Style; DataColumn; Button; Font; EventArgs; DataTable; DataView; LinkButton; Table; DataListCommandEventArgs; Page; DataRow; Object; CommandEventArgs; Import

DataList3 Sample

This sample illustrates editing items in DataList. The DataList control supports in-place editing of the data in an item through its EditItemTemplate property. The EditItemTemplate property defines the content and appearance of the item when it is being edited.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

DataList; TextBox; Binder; Label; Object; DataTable; EventArgs; DataBinder; Container; Table; Style; DataColumn; Button; CommandEventArgs; String; LinkButton; DataListCommandEventArgs; Header; Control; DataView; DataRow; Font; Import; Page

DataGrid2 Sample

This sample shows how to use BoundColumn. By explicitly creating a BoundColumn in the grid's Columns collection, you can control the order and rendering of each column.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

Header; DataGrid; BoundColumn; String; DataColumn; Font; Page; DataTable; Style; DataView; Table; Debug; EventArgs; Import; Form; DataRow; Object

DataList1 Sample

This sample illustrates using a simple DataList control. The DataList server control displays data items in a repeating list, and optionally supports selecting and editing the items. The content and layout of list items in DataList is defined using templates. At a minimum, every DataList must define an ItemTemplate; however, several optional templates can also be used to customize the appearance of the list.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

ListItem; DataList; DropDownList; Table; Button; String; Header; Font; Object; EventArgs; DataTable; DataView; Style; Page; Import; DataBinder; DataRow; Binder; LinkButton; Container; DataColumn; CheckBox

DataGrid11 Sample

This sample demonstrates how to hide the built-in pager user interface and supply your own paging UI. The DataGrid built-in page navigation controls, called the "pager," displays either as "next/previous" buttons or as a set of numeric page buttons.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

Page; DataGrid; Font; Button; Style; LinkButton; String; DataColumn; Object; EventArgs; DataTable; DataView; Label; Table; DataRow; Convert; Header; DataGridPageChangedEventArgs; Import

DataGrid12 Sample

This sample demonstrates using the DataGrid to work with large amounts of data. For very large data models, it is expensive to load the entire data source each time the grid is paged. A common alternative is to retrieve the data in page-size "chunks," rather than retrieving all the data and then stepping into the current row.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

Page; DataGrid; Label; Style; DataColumn; String; DataTable; Object; Table; DataView; EventArgs; Font; DataRow; DataGridPageChangedEventArgs; Import; Header

DataGrid10 Sample

This sample shows how to enable paging in DataGrid by setting the AllowPaging property to true. When enabled, the grid displays page navigation buttons either as "next/previous" buttons or as numeric buttons. When a page navigation button is clicked, the PageIndexChanged event is thrown. You must handle this event in your code. The most basic logic assigns the CurrentPageIndex to the event argument's NewPageIndex property and then rebinds the data source, as in this sample.

Namespaces used in this sample:

System.Data; System

Classes used in this sample:

Page; DataGrid; Style; DataColumn; Font; String; DataTable; Object; Table; Label; EventArgs; DataView; Header; DataGridPageChangedEventArgs; Import; DataRow

Namespaces used in this sample:

System.Web; System

Classes used in this sample:

Label; Button; Font; Object; Style; TextBox; HttpUtility; EventArgs

PlaceHolder1 Sample

This sample illustrates adding controls to a PlaceHolder. The PlaceHolder server control can be used as a container control within a document to dynamically load other controls. The PlaceHolder control has no HTML-based output and is only used to mark a location for other controls that can be added to the Controls collection of the PlaceHolder during page execution.

Namespaces used in this sample:

System.Web; System.Web.UI.HtmlControls; System; System.Web.UI

Classes used in this sample:

Button; Control; HtmlButton; PlaceHolder; Page; HtmlControl; Object; EventArgs; Import

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; CheckBox; HtmlInputCheckBox; EventArgs

HtmlForm1 Sample

This sample shows how an HtmlForm control is required to process post-back requests. A Web Forms page might only have one server-side <form> tag; however, client forms (without a runat=server attribute) can also post information back to server-side logic as long as a server-side form is present on the page.

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; EventArgs; Form; HtmlForm

HtmlButton1 Sample

This sample demonstrates using the HtmlButton control. The HtmlButton control renders as an HTML 4.0 <button>. This differs from <input type="button"> in that it enables Web developers to create rich user interface form buttons that can be composed from embedded HTML elements (and even other ASP.NET server controls).

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; EventArgs; HtmlButton

HtmlInputButton2 Sample

This sample demonstrates using the HtmlInputButton control. The HtmlInputButton control also supports the Reset and Submit button types, which are used only with forms. Submit submits the form, whereas Reset restores all the entry fields in a form to their initial values.

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; HtmlInputButton; EventArgs

ImageButton3 Sample

This sample shows how you can hook the client script events onmouseover and onmouseout to an ImageButton control to provide mouse-over effects such as changing the image source of the button. Client attributes such as onmouseover are disregarded by ASP.NET on the server, and passed "as is" to the browser. If your application targets newer browsers that support DHTML, these events occur in the browser as the pointer passes over the button.

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; Image; Label; ImageButton; Url; ImageClickEventArgs; EventArgs

Button1 Sample

This sample illustrates using a simple Button control. The Button server control provides a push button-style control that is used to post a Web Form back to the server.

Namespaces used in this sample:

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; ListItem; RadioButtonList; RadioButton; Label; EventArgs; Object; CheckBox; Table

HtmlInputRadioButton1 Sample

This sample shows how an HtmlInputRadioButton control creates a single radio button input field. Setting the Name attribute the same way on each radio button forms a group in which only one radio button can be selected at a time. The selected state must be tested on the individual radio buttons, however.

Namespaces used in this sample:

(none)

Classes used in this sample:

Button; RadioButton; EventArgs; HtmlInputRadioButton

Namespaces used in this sample:

(none)

Classes used in this sample:

File; Button; HtmlInputFile; Exception; EventArgs; String

CustomValidator1 Sample

This sample demonstrates using the CustomValidator server control to call a user-defined function to perform validations that the standard validators can't handle. The custom function can execute on the server or in client-side script, such as JScript or VBScript.

Namespaces used in this sample:

(none)

Classes used in this sample:

Font; CustomValidator; Page; EventArgs; TextBox; ServerValidateEventArgs; Label; Control; Button; Exception

RangeValidator1 Sample

This sample illustrates using the RangeValidator control. The RangeValidator server control tests whether an input value falls within a given range. RangeValidator uses three key properties to perform its validation. ControlToValidate contains the value to validate. MinimumValue and MaximumValue define the minimum and maximum values of the valid range. These constants are stored as string values, but converted to the data type defined by Type when the comparison is performed.

Namespaces used in this sample:

(none)

Classes used in this sample:

Font; Type; String; Button; RangeValidator; Page; Label; TextBox; Control; EventArgs; Object

RadioButton1 Sample
