Latest Internal Build fixes the problem ASP.NET_AJAX_2008_3_1319

CORRECTION: It isn't all of my Radgrids in the project but just some of them (I'm still working on figuring out why some work and other don't) ADDITION: It is on any column that is a number. It doesn't matter if it is gridboundcolumn or a gridnumericcolumn. TEMPORARY FIX I added DataType="System.String" to the column definition and filtering then works. It seem like a problem with the filter menu for numeric values.

I upgraded my sites to and now all of my filtering has stopped working on all of my RadGrids. They were all working before I upgraded. I get the error :
System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Header context menu column selection (checkbox) issue

Hello,

I'm using Telerik UI for ASP.NET AJAX build 2017.1.118.40 with the Metro theme.

My application has many RadGrid instances, and for some reason none of them are showing column checkbox selections correctly in their header context menus.

I've attached a screenshot to demonstrate. You'll see that the columns that should be checked (they are currently visible in the grid) are shown using a light blue color - but they aren't actually checked. If I explicitly toggle the checkbox (by clicking it), then it appears as expected, but only until the next postback.

I thought I might have some styles conflicting with this theme, but I've removed all my application's CSS (as a test), and nothing changed.

Has anyone else encountered this? Any thoughts or feedback would be greatly appreciated.

- Mark R.

How do I use radconfirm with asp:LinkButton's OnClientClick?

I'm trying to use the radalert instead of the browser confirm alert. Normally I would put this in the OnClientClick: return confirm('Are you sure you want to delete this file?');. But this does not work with radalert. I tried the below but nothing worked, mostly they just show the confirm window and it disappears after a second then the page continues to post without me even answering the confirm question. How do I achieve this?

OnClientClick="return radconfirm('Are you sure you want to delete this file?', confirmCallBackFn);"
OnClientClick="radconfirm('Are you sure you want to delete this file?', confirmCallBackFn);"
OnClientClick="radconfirm('Are you sure you want to delete this file?', confirmCallBackFn); return false;"
OnClientClick="return radconfirm('Are you sure you want to delete this file?', confirmCallBackFn); return false;"

<script>
function confirmCallBackFn(arg)
{
return arg;
}
</script>

Is there any easy way to use radconfirm like using asp.net confirm?

Hi there,

I am trying to use radconfirm instead of the asp.net confirm window. Following is my code for the asp.net delete confirmation window:

function Confirm_Delete() {

if (confirm("Are you sure you want to delete this?") == true)

return true;

else

return false;

}

<asp:Button ID="bt_Delete" runat="server" Text ="Delete" onclick="bt_Delete_Click" OnClientClick="return Confirm_Delete()" />

I have done the following changes in the javascript file, but it just show the delete confirmation window for a second, and then deleted the record without my input of Ok or not, Could anyone please let me know how to fix this issue? Thanks.

function confirmCallBackFn(arg) {

return arg;

}

function Confirm_Delete() {

radconfirm('<h3 style=\'color: #333399;\'>Are you sure you want to delete this?</h3>', confirmCallBackFn, 330, 100, null, 'Delete Confirmation');

}

#=dataitem.value# tags

Good day to forum members!

I have such a question-

what operations can I do with tags like #=dataitem.value# ?

In demos I saw expressions like

#=dataitem.value + dataitem.value1 + ...#

So, what else can I do with these ones?

Can I use any math function?

Can I round result?

One yet thing - can I work with #=dataitem.value# like operator in my .cs file? For example, convert it to value type? Something like decimal d=Convert.ToDouble("#=dataitem.value {0}", 1); ?

I'm not successful in any of these things;

Sorly, I'm new in telerik and ASP.
