  How to fill values of a dropdownlist by using selected index changed event of another dropdownlis...

  Jun 12, 2012 01:10 PM|LINK

  I have a dropdownlist1 which has been manually filled. I have a code behind to fill another dropdownlist2 using dropdownlist1's selected indexchanged event.
  
  I tried Autopostback="true" for dropdownlist1.

  It loads the listitems for the first selection.
  
  But when i change the selection, it does not post back. The list items remain the same.
  
  Please help me... Thanks!

  here is the Sample Code..

  protected void ddlRewardType_SelectedIndexChanged(object sender, EventArgs e)

  {

  LoadScorecardNames();

  }

  private void LoadScorecardNames()

  {

  ddlScorecardName.DataTextField ="ScorecardName";

  ddlScorecardName.DataValueField ="ScorecardId";

  ddlScorecardName.DataSource = <<dataSource>>;

  ddlScorecardName.DataBind();

  }

  Thats a Sample which I pulled from Code. Please try to implement in a similar Way.

  Thanks
