Property Value

Examples

The following code example demonstrates programmatic use of the ID property. For the full code required to run this code example, see the Example section of the WebPartDescription class overview topic.

The following code in the Button1_Click method of a Web page demonstrates how to get the collection of WebPartDescription objects in a catalog using the GetAvailableWebPartDescriptions method, and then to display the details of each WebPart control in the catalog by looping through the WebPartDescription objects. Note that the ID property value is retrieved in the following code.

protected void Button1_Click(object sender, EventArgs e)
{
  Label1.Text = String.Empty;
  
  WebPartDescriptionCollection descriptions = 
    DeclarativeCatalogPart1.GetAvailableWebPartDescriptions();

  foreach (WebPartDescription desc in descriptions)
  {
    Label1.Text += "ID: " + desc.ID + "<br />" +
      "Title: " + desc.Title + "<br />" +
      "Description: " + desc.Description + "<br />" +
      "ImageUrl: " + desc.CatalogIconImageUrl + "<br />" +
      "<hr />";
  }
}

Protected Sub Button1_Click(ByVal sender As Object, _
  ByVal e As System.EventArgs)
  
  Label1.Text = String.Empty
      
  Dim descriptions As WebPartDescriptionCollection = _
   DeclarativeCatalogPart1.GetAvailableWebPartDescriptions()
          
  Dim desc As WebPartDescription
      
  For Each desc In descriptions
    Label1.Text += "ID: " & desc.ID & "<br />" & _
      "Title: " & desc.Title & "<br />" & _
      "Description: " & desc.Description & "<br />" & _
      "ImageUrl: " & desc.CatalogIconImageUrl & "<br />" & _
      "<hr />"
  Next
  
End Sub

Remarks

The value of the ID property cannot be null; it must always have a value. The ID property corresponds directly to the Control.ID property.

The ID property applies only when a page is in catalog display mode, and a WebPart control is being displayed in a catalog of controls.
