RadCombobox closing when select a Row from RadGrid

[Muhammad]

I have placed my radGrid inside a Radcombobox but I try to open a radcombobox by calling OnClientDropDownOpening="OnClientDropDownOpening" using ajax request it gets closed automatically.

 function OnClientDropDownOpening(sender, args) {
            var comboText = sender.get_text();
            if (comboText.length > 2) {
                 $find("<%= rapJob.ClientID %>").ajaxRequest("LoadFilteredData," + comboText);
            }
            else {
                args.set_cancel(true);
            }
        }

 Protected Sub rapJob_AjaxRequest(ByVal sender As Object, ByVal e As AjaxRequestEventArgs)


        Dim rgJob As RadGrid = TryCast(rcbJob.Items(0).FindControl("rgJob"), RadGrid)
        If e.Argument.IndexOf("LoadFilteredData") <> -1 Then
            rgJob.Rebind()
        End If


    End Sub


    Protected Sub rgJob_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs)


        Dim rgJob As Telerik.Web.UI.RadGrid = source


        Dim IJobs = (From Jobs In dbContext.FF_Jobs Where Jobs.IsCreated = True And Jobs.IsCancelled = False And Jobs.IsTemplate = False
                    Select Jobs).ToList


        rgJob.DataSource = IJobs


    End Sub

I have placed Radcombobox inside radGrid.
Now try to remains opened radcombobox by calling OnClientDropDownOpening="OnClientDropDownOpening" using ajax request.

Hello,

This behavior of RadComboBox is normal since whenever you try to open the drop-down list the event is either terminated or there is a trip to the server after which the RadComboBox renderer with its drop-down closed.

If you want to learn more about the client API of the control, refer to the following documentation:  http://www.telerik.com/help/aspnet-ajax/combobox-client-side-basics.html.

All the best,
