Handling Multiple AsyncPostBackError Types?

Our Framework has gotten to a point where we need to handle AsyncPostBackErrors in different ways on the same page. Here is an example of my problem in short. We want to display ErrorTextA using an "alert();" if an error is thrown in systemA... which is simple enough. But on the same page we want ErrorTextB to be displayed on a label if an error is thrown in systemB. Is there a way to Differentiate between the two or have two AsyncPostBackError handlers on the same page? Basicly I need to know if the error came from SystemA or SystemB.

SelectedIndexChanged trigers during button click

Hi Telerik,

I am using the rad grid user control edit form. Inside the user control i have a list box which populates the data dynamically.
I have a selectedindexchanged fn trigered whn i click on the items in the list box that works fine. I have 10 items in the listbox after randomly clicking few items when i click the update or cancel button, the selectedindexchanged fn gets fired first and then the
control goes to the update in the aspx.cs page, This also happens once in a while.The grid is placed in the Ajax panel. Do you people have any idea about this. Please let me know your ideas on this.

Thanks
Arun.M

Showing only selected Nodes

Hi,
I am trying to build a tree view and it works fine with just a normal datatable bound to it and shows everything. But I want to be able to pass a value such as '3' to the parent value and then for the treeview to show me all the child records under 3 and also all there grandchildren.

ID        ParentID
1            Null
2             1
3             1
4             3
5             3
6             4
7             6
8             5

I hope that makes sense

Thanks

Select first row and pass ID (VB)

Hi,

When the grid loads or is paged or sorted - I need to have the first row selected and to be able to pass the ID of that row to a seperate details section on the same page. (The ID is taken by a data reader which populates some labels) - Is this possible please?

For selecting the row, I tried converting the SelectFirstGridRow from the WebMail demo but in VB 'OfType' was not available.

    
            private void SelectFirstGridRow()  
        
                {  
        
                    GridDataItem firstDataItem = RadGrid1.Items.OfType<GridDataItem>().FirstOrDefault();  
        
                    if (firstDataItem != null)  
        
                        firstDataItem.Selected = true;  
        
                }  
        
            Private Sub SelectFirstGridRow()  
        
                Dim firstDataItem As GridDataItem = RadGrid1.Items.OfType(Of GridDataItem)().FirstOrDefault()  
        
                If firstDataItem <> Nothing Then  
        
                    firstDataItem.Selected = True 
        
                End If  
        
            End Sub

Frozen columns in a Popup Panel

Hi,

I'm trying to display a Grid in a Popup Panel. The problem is when the popup is first diplayed the columns are not frozen. Only after I click on a column's header for sorting, will the "column freezing" work.
Any idea why is that so? Or how to fix this and make the "column freezing" work on display?

Thanx.

RadAjaxManagerProxy and UpdatedControls

Hi,

I have a master page which has RadAjaxManager in it , and web user control that has a simple form & simple controls on it with a submit linkbutton. On my user control I have a Radcombobox which is ajaxified by RadAjaxManagerProxy and I set the UpdatedControls prior to it. These are some labels, some textboxes and 1 submit linkbutton.

As I expected the Radcombobox does ajax post back and updates the controls needed. But when I click to the linkbutton which submits the form of web user control, it does nothing. Then I figured out that it does what it is expected, but doing postback in ajax . I mean the page is not normal postbacking. The button also ajaxifed. But I set the button only UpdatedControls setting of Radajaxmanagerproxy. When I remove the button from updated controls it postbacks normally which I wanted to be. I am ajaxifiying it because according to the combobox 's value i am enabling or disabling the linkbutton. So I need to add linkbutton to updatedcontrols collection. But I donot want its postback feature being ajaxified.

Here is my Radajaxmanagerproxy definitions

<

telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<telerik:AjaxSetting AjaxControlID="ddl">

<telerik:AjaxUpdatedControl ControlID="lbl1" LoadingPanelID="RadAjaxLoadingPanel1" />
