IWebPart.Description Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a brief phrase that summarizes what a control does, for use in ToolTips and catalogs of WebPart controls.

Namespace: System.Web.UI.WebControls.WebParts
Assembly: System.Web (in system.web.dll)

string Description { get; set; }
/** @property */
String get_Description ()

/** @property */
void set_Description (String value)

function get Description () : String

function set Description (value : String)

Property Value

A string that briefly summarizes the control's functionality. The default value is an empty string ("").

The Description property value is typically used as a descriptive string for a control in catalogs that provide lists of WebPart controls, and as a ToolTip in a control's title bar. The content of the property appears in a ToolTip when a user positions the mouse pointer over the title text in a control's title bar.

The following code example demonstrates declarative and programmatic use of the Description property. The complete source code for the example is found in the Example section of the IWebPart class overview.

The first part of the code example shows how the user control implements the Description property.

public string Description
    object objTitle = ViewState["Description"];
    if (objTitle == null)
      return String.Empty;

    return (string)objTitle;
    ViewState["Description"] = value;

The second part of the code example demonstrates the method in the user control that programmatically sets the value of the Description property when a user selects the appropriate property name from the radio buttons on the page, sets a new value in the text box, and then clicks the Update button.

// Update the selected IWebPart property value.
void Button1_Click(object sender, EventArgs e)
  String propertyValue = Server.HtmlEncode(TextBox3.Text);
  TextBox3.Text = String.Empty;

  switch (RadioButtonList1.SelectedValue)
    case "title":
      this.Title = propertyValue;
    case "description":
      this.Description = propertyValue;
    case "catalogiconimageurl":
      this.CatalogIconImageUrl = propertyValue;
    case "titleiconimageurl":
      this.TitleIconImageUrl = propertyValue;
    case "titleurl":
      this.TitleUrl = propertyValue;

The third part of the code example shows how the user control that implements the IWebPart interface is referenced in a WebPartZone control, and how the Description property is set declaratively on the control. Note that you can see the value of this property by positioning your mouse pointer over the title text in the control's title bar, after you have loaded the page in a browser. You can also experiment with changing the property value programmatically at run time by loading the Web page and using the provided user interface (UI) to change the property value.
