CommandField.SelectImageUrl Property

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

Gets or sets the URL to an image to display for a Select button in a CommandField field.

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

public virtual string SelectImageUrl { get; set; }
/** @property */
public String get_SelectImageUrl ()

/** @property */
public void set_SelectImageUrl (String value)

public function get SelectImageUrl () : String

public function set SelectImageUrl (value : String)

Property Value

The URL to an image to display for a Select button in a CommandField. The default is an empty string (""), which indicates that this property is not set.

When the ButtonType property of a CommandField field is set to ButtonType.Image, use the SelectImageUrl property to specify the image to display for a Select button. This image can be in any file format (.jpg, .gif, .bmp, and so on), as long as the client's browser supports that format.

NoteNote

As an alternative to displaying an image for a Select button, you can display text by first setting the ButtonType property to ButtonType.Button or ButtonType.Link and then setting the SelectText property.

The following code example demonstrates how to use the SelectImageUrl property to specify a custom image to display for a Select button in a CommandField field of a GridView control. The ButtonType property must be set to ButtonType.Image for a Select button to display an image.


<%@ Page language="C#" %>

<script runat="server">
  
  void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
  {
    // Retrieve the company name from the appropriate cell.
    String companyName = CustomersGridView.SelectedRow.Cells[2].Text;
   
    // Display company name selected by the user.
    Message.Text = "You selected " + companyName + ".";
  }
  
</script>
