![]() | DataTextField | Gets or sets the field from a data source to bind to the text caption of the hyperlinks in the HyperLinkColumn. |
![]() | DataTextFormatString | Gets or sets the display format for the text caption of the hyperlinks in the HyperLinkColumn column. |

![]() | Target | Gets or sets the target window or frame to display the Web page content that is linked to when the hyperlink in the column is clicked. |
![]() | Text | Gets or sets the text caption to display for the hyperlinks in the column. |

![]() | Visible | Gets or sets a value that indicates whether the column is visible in the DataGrid control. (Inherited from DataGridColumn.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | FormatDataNavigateUrlValue | Formats a data-bound URL using the format specified by the DataNavigateUrlFormatString property. |

![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | Initialize | Provides the base implementation to reset a column derived from the DataGridColumn class to its initial state. (Overrides DataGridColumn::Initialize().) |
![]() | InitializeCell | Initializes the cell representing this column with the contained hyperlink. (Overrides DataGridColumn::InitializeCell(TableCell, Int32, ListItemType).) |
![]() | LoadViewState | Loads the state of the DataGridColumn object. (Inherited from DataGridColumn.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnColumnChanged | Calls the DataGridDesigner::OnColumnsChanged method. (Inherited from DataGridColumn.) |
![]() | SaveViewState | Saves the current state of the DataGridColumn object. (Inherited from DataGridColumn.) |
![]() | ToString | Returns the string representation of the column. (Inherited from DataGridColumn.) |
![]() | TrackViewState | Causes tracking of view-state changes to the server control so they can be stored in the server control's System.Web.UI::StateBag object. (Inherited from DataGridColumn.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IStateManager::IsTrackingViewState | Infrastructure. Gets a value that indicates whether the column is tracking view state changes. (Inherited from DataGridColumn.) |
![]() ![]() | IStateManager::LoadViewState | Infrastructure. Loads previously saved state. (Inherited from DataGridColumn.) |
![]() ![]() | IStateManager::SaveViewState | Infrastructure. Returns an object containing state changes. (Inherited from DataGridColumn.) |
![]() ![]() | IStateManager::TrackViewState | Infrastructure. Starts tracking state changes. (Inherited from DataGridColumn.) |
Use the HyperLinkColumn column type in a DataGrid control to create a hyperlink for each row in the DataGrid. Set the Text property to specify the caption text for the hyperlink. To specify the URL to link to when the hyperlink is clicked, set the NavigateUrl property.
Note |
|---|
If you set the Text and NavigateUrl properties, all hyperlinks in the column will share the same caption and URL. |
You can also bind the text caption and URL of the hyperlinks in the HyperLinkColumn to a field in a data source instead of setting the Text and NavigateUrl properties. This allows you to display a different caption and to specify a different URL for each hyperlink in the column.
Use the DataTextField property to specify a field in a data source to bind to the text caption of the hyperlinks in the column.
Note |
|---|
The DataTextField and Text properties cannot both be set at the same time. If both properties are set, the DataTextField property takes precedence. |
Specify the field to bind to the URL of the hyperlink by setting the DataNavigateUrlField property.
Note |
|---|
The DataNavigateUrlField and NavigateUrl properties cannot both be set at the same time. If both properties are set, the DataNavigateUrlField property takes precedence. |
The Target property allows you to specify the window or frame to display the Web page content linked to when the hyperlink is clicked.
When using data binding, you can format the text caption and URL of the hyperlink by setting the DataTextFormatString and DataNavigateUrlFormatString properties, respectively.

This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. You can use validation controls to verify user input before displaying the input text in a control. ASP.NET provides an input request validation feature to block script and HTML in user input. For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages. |
The following example demonstrates how to create a HyperLinkColumn that links to a separate page.
