Hi,

I just upgraded to version 2012.3.1016.35 of the ASP.NET for AJAX controls, and the problem I'm facing was caused by the upgrade (I upgraded from version 2011.3.1305.35),

I use RadGrids with a GridClientSelectColumn and the following client settings:

<ClientSettings AllowDragToGroup="false" AllowRowsDragDrop="false">
<Selecting AllowRowSelect="true" />
</ClientSettings>

PROBLEM:
When the browser window has a scrollbar (content is extending beyond the bottom of the window) and when a grid extends down into the scrollable area (it extends beyond the bottom of the screen), when I click on a row in the grid, the browser window is scrolled up and the row in the grid is NOT selected. In other words, the first click in a row in the grid, acts like a bookmark and "jumps" the page so that the grid is moved up higher...

When I click the row again (or even a different row), the row is then selected as expected.

However, if I then scroll the browser window back to the top (so that the grid again moves down) and click a row again, I get the same behavior. The row isn't selected, and instead the grid is scrolled / jumped up.

QUESTION: What has changed, and what can I do to resolve this?

Another big problem this causes is that I actually have a column in the grid that I use for navigation (clicking the name of an item navigates the user to other pages). With this bad behavior, the first click on my link simply moves the grid up and the user has to click the link again in order to navigate...

MORE INFO:
- This is happening to ALL of my RadGrids that have AllowRowSelect=true and have a GridClientSelectColumn.
- If I set AllowRowSelect=false and remove the GridClientSelectColumn, the problem doesn't occur.
- This NEVER happened until I upgraded to the most recent version (we've used ASP.NET for AJAX for 4+ years). I still have the 2011.3.1305.35 version in our production environment, and the problem does NOT occur.
- It happens on all browsers

- I actually also use the setting below, but it doesn't change the behavior. In fact, the first time you click a row, the CancelNonInputSelect function isn't even called! I know that, because I put a debugger statement in it. When I click the row the second time, it is then called.

<ClientEvents OnRowSelecting="CancelNonInputSelect" OnRowDeselecting="CancelNonInputSelect" />

Where my CancelNonInputSelect function is:

function CancelNonInputSelect(sender, args) {
var e = args.get_domEvent();
//IE - srcElement, Others - target
var targetElement = e.srcElement || e.target;
//this condition is needed if multi row selection is enabled for the grid
if (typeof (targetElement) != "undefined") {
//is the clicked element an input checkbox? <input type="checkbox"...>
if (targetElement.tagName.toLowerCase() != "input" &&
(!targetElement.type || targetElement.type.toLowerCase() != "checkbox"))// && currentClickEvent)
{
//cancel the event
args.set_cancel(true);
}
}
else
args.set_cancel(true);
return false;
}

PLEASE HELP! This functionality alone, would prevent us from upgrading to your most recent version.

Hi,

Thanks a lot for the post here. I too faced the same issue when we are trying to migrate to new telerik controls and was able to rectify the behavior where in it let me click on the button in the grid even after scrolling. But I lost the functionality where in I could choose multiple rows by Click Drag and Release mechanism

FYI: I have also set the property EnableDragToSelectRows="true"
But the multiselect functionality stops working as soon as I set the property UseClientSelectColumnOnly="true"

I need both the functionility in my grid.
1. I need to be able to click button in the grid to navigate to other webpage.
2. I also need to be able to multiselect rows(Click Drag and Release).
I have tried all combination unable to get it to work, not sure what I am doing wrong.

IE version: 8.0
Telerik version: 2012.3.1016.40

Please also be informed we have initiated the procurement of new version of telerik and we are using trial version to start off with migration and hence we would really appreciate if you could help though the 30 day trail period is over.
Thanks in advance.

Lohitha

Hello,

Try to ajaxify the container asp Panel like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="grdPanel">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="grdPanel"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

and see how it goes.
