Hi Dinko, 

Thank you for your response. Let explain about dynamic dropdownlist in my next forum.

Now we need fix for the below items.

As I mentioned in the previous forum, We need fix for Raddropdownlist.DataSource as well as Raddropdownlist.SelectedIdex.

When we set the Datasource as well as SelectedIndex=5 or some value in selectedIndexchangedEvent then the recursive call is happening so we need to restrict for  both Raddropdownlist.DataSource as well as Raddropdownlist.SelectedIdex.

  private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
        {
           fillIndustryProcess1(); // radDropDownList1.DataSource = dt; when we set Datasource the recursive call is occurring
            radDropDownList1.SelectedIdex = 5;

}

public void fillIndustryProcess1()
        {
            try
            {
                System.Data.DataTable dt = new System.Data.DataTable(); //this will be local instantiation throughout product 
                if (dt.Columns.Count > 0)
                    {
                        dt.Columns.Add("Industry", typeof(string));
                        dt.Columns.Add("ID", typeof(int));
                        dt.Rows.Add("BGL-0", 0);
                        dt.Rows.Add("BGL-1", 1);
                        dt.Rows.Add("BGL-2", 2);
                        dt.Rows.Add("BGL-3", 3);
                        dt.Rows.Add("BGL-4", 4);
                        radDropDownList1.DisplayMember = "Industry";
                        radDropDownList1.ValueMember = "ID";
                    }       
            }
            catch (System.ComponentModel.Win32Exception ex)
            {
                throw ex;
            }
        }

Thanks,

Hi Dinko,

Our code will be dynamic where the Raddropdownlist can be anything, in such case how we can find the Raddropdownlist  having selectedIndexChanged event or not.? Is there any way to find the SelectedIndexChanged for dynamic  Raddropdownlist?

   private void FillSelectionCombo(Telerik.WinControls.UI.RadDropDownList tempCombo, Common.Attributes AttID, int ModelID)
        {
            try
            {                
                tempCombo.DisplayMember = "Name";
                tempCombo.ValueMember = "ID";

    tempCombo.SelectedIndexChanged -= new Telerik.WinControls.UI.Data.PositionChangedEventHandler(this.tempCombo_SelectedIndexChanged); // This will throw error
                tempCombo.DataSource = Common.GetValidValues(((Common.Model)ModelID), AttID, ((Common.Manufacture_Site)PNxt_BL.LineItem.CurrentLineItem.SiteId), PNxt_BL.LineItem.CurrentLineItem.QuotationDateCnt, 1);
                if (tempCombo.Items.Count > 0)
                {
                    tempCombo.SelectedIndex = 0;
                }
    tempCombo.SelectedIndexChanged += new Telerik.WinControls.UI.Data.PositionChangedEventHandler(this.tempCombo_SelectedIndexChanged);// This will throw error
            }
            catch (Exception ex)
            {

            }
        }

Hi Dinko,

Already we had spent much time to do subscribe and unsubscribe even though it was not working. If is it doable we supposed to do. We put lot of effort however it was ended up with stackoverflow exception. It is legacy project hence we are getting trouble when try to use latest Telerik.

In my previous forum, I had highlighted this issue in back ground color. However it was not fixed.

So could you please tell me when it will be fixed to test and purchase?

Thanks,

Maheswari
