[Solved] SelectedValue

[Pablo Tola]

I have two ComboBoxes on my page, I need to get the selected value from the first one on the ItemsRequested event of the second one server side, I'm getting null.

Hi Pablo Tola,

I suggest to achieve your approach by hooking on OnClientItemsRequesting event of the second combo and setting the context property:

function OnClientItemsRequesting(sender,eventargs)
                {
                    var combo = $find("RadComboBox1");  //this is the first combo

                    var c = eventargs.get_context();
                    c["ComboValue"] =combo.get_value();
                    c["ComboText"] =  combo.get_text();
                }

Then you can get these values in the ItemsRequested in the following way:

protected void RadComboBox2_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)
        {
            string value = e.Context["ComboValue"].ToString();
            string text = e.Context["ComboText"].ToString();
        }

Hope this helps.

All the best,
