  User control - event exposed to page (raise manually)

  Sep 22, 2009 02:07 AM|LINK

  Hi,

  I wrote a user control in which I am creating grid inside PanelBar dynamically.

  In New ItemTemplate I am creating grid and adding handler for Grid_rowdrop event.

  So, my ASCX.VB FILE has code like below

  MyUserControl.ASCX File:

  Protected Class MyUserControl
  	Inherits System.Web.UI.Control
  
  
  RadPanel_ItemDataBound Event
  	locationsPanel.ItemTemplate = new MyTemplateClass()
  
  
  End Class
  
  
  Class MyTemplateClass
  	Implements ITemplate
  
  
  Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn
  	' Create Dynamic RadGrid here
  	' and add RowDrop handler.
  End Sub
  
  
  	Protected Sub MyDynamicGrid_RowDrop(ByVal sender As Object, ByVal e As GridDragDropEventArgs)
  	' I WANT TO CALL THIS EVENT FROM ASPX PAGE ON BUTTON CLICK. WHICH IS OUTSIDE OF THIS USERCONTROL
  	' AND OFCOURSE NOT PART OF THIS DYNAMIC GRID
  
  
  	End Sub
  
  
  End Class

  
  

  How to call/Raise "MyDynamicGrid_RowDrop" Event from ASPX page?

  Thanks

  Based on my experience, I suggest you solve it by using Delegate. Please refer to the following articles to get some ideas:

   hi,

  in usercontrol1 define event like below

  delegate void ButtonClick(Object sender, EventArgs e);

  public

   

  public event ButtonClick OnButtonClick;

  if (this.OnButtonClick!= null)

  public void BubbleclickButtonClick(object sender, EventArgs e)    

   

      {   

      this.OnButtonClick(sender, e);}

   

  In page code like below

  public partial class Default: System.Web.UI.Page
  {  
      protected void Page_Load(object sender, EventArgs e)  
      {   
    
      this.UserControl1.OnButtonClick+= new UserControl1.ButtonClick (UserControl1_OnButtonClick);
  }
  
  void UserControl1_OnButtonClick(object sender, EventArgs e)
  {

  // write your code to update other control textbox using property

  }

   

  Thanks,
  Karthick S
