Radlistbox enable/disable checkbox

[Tamim]

Hi all,
I have used 2 RadlistBox to assign some email id in both Radlistbox.
First listbox mail id check same mailid enable false in another RadListBox how to check

My sample coding here

protected void ToEmail_ItemCheck(object sender, Telerik.Web.UI.RadListBoxItemEventArgs e)
        {
            ToName.Text = "";
            int i = 0;
            foreach (object obj in ToEmail.CheckedItems)
            {
                string ema;
                string item1 = ToEmail.CheckedItems[i].Value;
                ToName.Text += ',' + item1;
                ema = ToEmail.CheckedItems[i].Value;
                foreach (RadListBoxItem item2 in ToEmailCC.Items)
                {
                    if (ToEmailCC.Items[i].Value == ema)
                    {
                        item2.Enabled = false;
                    }
                }
                i++;
            }
        }

Thanks & Advance,

Hello Ansari,

I am not quite sure that I understood your scenario. Assuming that you have 2 RadListBoxes populated with identical data and you want to disable the item from the second RadListBox, corresponding to the one, checked in the first RadListBox I could suggest you the following implementation :

protected void RadListBox1_ItemCheck(object sender, RadListBoxItemEventArgs e)
   {
       RadListBoxItem currentlyCheckedItem = e.Item;

       foreach (RadListBoxItem item2 in RadListBox2.Items)
       {
           if (item2.Value == currentlyCheckedItem.Value)
           {
               item2.Enabled = item2.Enabled ? false : true;
           }
       }
   }

Here is a video, demonstrating the behavior at my end.

Kind regards,
