Questions on UI for ASP.NET AJAX Forum

I am not sure under which section this post should go...but it would be great if you could help me find a solution.

I have a hidden field inside an AJAXpanel alongwith a grid and other controls.
The grid has 2 dropdown controls. On the clientselectedindexchanged event of the frist dropdown I put the selection in a hidden field.

On the items requested event of the second dropdown i want to read the value from that hidden field and filter the dropdown.

I am able to set the value of the hidden filed.
But on the itemsrequested evnt for the second combo the hidden field loses the value. I also tried this with a textbox with its display set to none.

If I force a postback in my javascript function then the value in hidden field shows.
I know it has something to do with the AJAX postback but I am not sure how I can work around this.

Any help would be appreciated.

Returning False Not Canceling Tab Select

I am trying to provide a confrimation prompt that would allow a user a second affirmation before actually changing tabs. Problem is it doesn't work, no matter what the user does, the tab is selected and the server event is fired.

    
                function ClientTabSelecting(sender, eventArgs)  
        
                {  
        
                   var tabStrip = sender;  
        
                   var tab = eventArgs.Tab;  
        
                   return confirm("Are you sure you want to navigate away from this page?");  
        
                }

<

telerik:RadTabStrip ID="RadTabStrip1" Width="100%" runat="server" Skin="Hay" OnClientTabSelecting="ClientTabSelecting" multipageid="RadMultiPage1" AutoPostBack="false" PerTabScrolling="true" ScrollButtonsPosition="Middle" />

    
             protected override void OnInit(EventArgs e)  
        
                {  
        
                    base.OnInit(e);  
        
                    RadTabStrip1.TabClick += new RadTabStripEventHandler(TabClicked);  
        
                }

RadTreeView + RadContextMenu Disabled Item Issue

I have a scenario similar to your example here:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Treeview/Examples/Functionality/ContextMenu/DefaultCS.aspx

I have a specific context menu being used on the root element and a different one for all child elements (there will always only be one root). The context menu item seems to always be disabled on the root one (just like in the demo) and I need to get it enabled somehow.

Any suggestions?

Positioning the AutogenerateDelete Column.

Hai,

I want to place the AutoGenerateDelete column to the last column of the grid even though my columns of the grid are autogenerate.

I gave true for the AutoGenerateColumn and the AutoGenerateDelete column, but the AutoGenerateDelete column is come first rather than the AutoGenerateColumns.

Is it possible for me to position the AutoGenerateDelete column next to the AutoGeneratColumns, ie AutoGenerateDelete column should come at the last column of the grid.

Thanks and Regards,
Sushanth Mathew

Refresh mastertable after inserting/updateing detail

Halo all

I have 2 level grid.
Master - Detail.
I use NeedDataSource to bind to db.
When i insert/update the detail,
i need to sum the detail and show on master.

On UpdateCommand event,
i use grid.Rebind() to refresh the grid.
It works as i want, but the edit form is not close.
Edit form will close (as normal) if i am not using rebind()

I have tried to rebind and call the e.item.edit = false,
but it will close all the hierarchy.

Is there any way to call Rebind() in UpdateCommand event
and close the editform template?

Or is there any other better way, to refresh the master when any changed on the detail?

Thanks in advanced.

map keyboard support of radgrid for enter key to open radwindow rather than postback

I have a template column with an image button that when clicked opens a radwindow through javascipt to edit an item in the grid. This proces works well.

<telerik:GridTemplateColumn

UniqueName="TemplateEditColumn"

HeaderText="View/Edit"

HeaderStyle-Width="100">

<asp:ImageButton ID="EditButton" OnClientClick='<%# Eval("ID", "openEditCommentWindow({0}); return false;" ) %>' runat="server" ImageUrl="./images/edit.gif"></asp:ImageButton>

</ItemTemplate></telerik:GridTemplateColumn>

this is the jascript that it calls:

function openEditCommentWindow(CommentID)

{

var oWnd = radopen("CommentDetail.aspx?CommentID=" + CommentID, "Edit Comment");

oWnd.set_modal(

true);

oWnd.Center();

}

So my issue is that I am trying to build an application to minimize mouse use and generally use the keyboard support of the grid to place the grid into edit mode by setting

ClientSettings-AllowKeyboardNavigation="true"

whihc is a relly nice feature.

The problem is that pressing the enter key while having a row selected causes a postback to the radGridComments_ItemCommand rather than opening a client side radwindow.

How can I hook up the enter key to the openEditCommentWindow javascript function?

Thanks much

Jonathan
