Multiple Child Grids & Selecting Appropriate Row

I have three master /detail RadGrids like:

--1
----2
------3

I am trying to ensure two scenarios:

How can I make sure the appropriate rows are selected and the correct child data loaded for when the page loads and the user clicks a row in any grid?

I tried accessing the SelectedItems during Page_PreRender but only succeeded in selecting the first rows on page load, not when the user clicks a row. I tried the solution found on this site to always select a row but the code did not work for me.

Is this possible in changing column of showing detail view ?

Hi all,

I am using RadGrid with NestedViewTemplate is another RadGrid for showing Master - Detail data. As the default, when you click on the icon in the first column to show the detail view.

Could I change this by clicking on another column (I don't want to use the first column and of course its icon).
Thank you,
Phuc PHAM

radbutton popup is blocked

hello

i am currently replacing some buttons with the radbutton.
for buttons and linkbuttons i was setting the "onclick" attribute to call a JS-function which opens a popup after checking if it isn't already open which should be avoided when using radbutton.
so i adapted the code to use the radbuttons OnClientClicking property to

"function(sender,args){" + javaScriptCall + "}";

where javaScriptCall calls the JS-function which returns a window:

top.Popup1 = OpenWindowWithCheck(top.Popup1, 'url', 'errormessage','Popup1')

and here is the function:

function OpenWindowWithCheck(Window, PagePath, ErrorMessage, WindowName)
{
    if (Window == null || Window.closed) {
        Window = window.open(PagePath, WindowName);
    }
    else {
        if (confirm(ErrorMessage))
        {
            Window.close();
            Window = window.open(PagePath, WindowName);
        }
        else
        {
            Window.focus();
        }
    }
    return Window;
}

This works well except that i get a popup-blocker message by IE9 now.
How can i avoid this popup-message or is there another way to call my JS-function with radbutton?

EmptyMessage disappears on Ajax Postback

I've got 3 textboxes and an InputManager that sets the EmptyMessages of these textboxes. On initial page load, the empty messages are displayed fine, however on an Ajax postback of a radcombobox, these empty messages disappear and leave the textboxes blank.

Why is this happening? Thanks.

Export To Excel issue on a Master Child Grid data

Hi,

I have implemented a master child rad grid , where the child data for a particular row gets loaded only when user clicks on the uncollapse icon next to the mater data for a particular row.

Now when I am doing an export to excel via ItemCommand, i found that it also tries to load the child data by calling Childgrid_NeedDataSource before doing an export. Is there a way I can stop from doing that and only export the master data?

Note: I am having this issue only when I set IgnorePaging to true. Its works fine with IgnorePaging to false.

Any suggestions
