I can tell a column to do a sum of all its values and the sum will be displayed in the footer fo the grid. How exactly does the grid do this? Is it using Linq? I ask because I need to do a custom aggregate, and in order to do this custom aggregate i need all of the values in the column for each group.

For example, if I could do something along the lines of "select all values from rad grid where column = e.column and group =  ??" that would be great. As you can see I'm not really sure how to know what group I am in either. I've seen examples using looping in the PreRender event but how can this be done in the CustomAggregate event?

Thanks!

when in my Window i call oWindow.close(); it works perfect for both IE/89 and Mozila 4/5
but in Chrome somthing funny is happening. it closes the window then it opens an empty  window !!!

this is how i call the window (MainPage.aspx)

            <telerik:RadWindow ID="RadWindow_QuikInfo" runat="server" Behavior="Default" InitialBehavior="None"
                    ShowContentDuringLoad="false" OpenerElementID="Button1" 
                    VisibleOnPageLoad="false" NavigateUrl="~/Win1.aspx" 
                    Behaviors="Close,Move,Resize,Reload" >
            </telerik:RadWindow>

and this is how i try to close window (Win1.Aspx)

            function AdjustRadWidow() {
                var oWindow = GetRadWindow();
                if (1 == 1) oWindow.close();
                setTimeout(function () { oWindow.autoSize(true); if ($telerik.isChrome || $telerik.isSafari) ChromeSafariFix(oWindow); }, 500);
            } 

This must be very simple, so I assume I am at fault for not knowing how to do it!

I have a RadGrid with a check-box (not populated from the data-source) as follows:


I want to be able to select certain items for printing by ticking the relevant boxes.  I can tick the boxes perfectly well but if I change page and then come back again, the ticks are removed.  How can I enable them to retain their state?  I am using a RadAjaxManagerProxy on the page (with a RadAjaxManager in the corresponding master-page) for partial post-backs: I have tried removing this but the check-boxes still lose their state after paging.

I am using Telerik DLL 2010.2.713.40 under Windows Server 2008.

I have a requirement where i have a Telerik grid which is bound to a list of a custom collection. The structure of the collection is
List (Of Assignment), which is bound to my grid. I have a couple of bound columns which are bound to the string properties. I also have a template column, where i want to have another grid, which gets bound to AssignedToList. This binding should be two-way. How can I achieve this ?

Hi,
I have the following scenario:
A RadTabStrip that has 4 tabPages.
On first page i have some textboxes with validators on it.

I want to do the following:
when i try to change the page, the notification should show up if there are validation errors.
I want this done on client side script.

It looks that the validation fires before any onClient... event of the RadTabStrip.
If i use a button inside the TabPage and i attach the script to the button, everything works fine.

Please give me a solution.
Thanks,

I've got an issue with RadComboBox where the style is incorrectly loading. In the CSS the style is being supplied by both WebResource.axd and Telerik.Web.UI.WebResouce.axd under the same style reference names.

Using the F12 tools in IE9, it seems to ignore the style provided by WebResource.axd and uses the Telerik.Web.UI.WebResource.axd declaration instead. All of the settings specified works except one, the background-image attribute.

url("/WebResource.axd?d=zOVDqaYoPgeOeTYRB8nFIraLP5bLJSS9mMvDXS2Gx92JFqyRrNGZriTPN9mB7xlBQFxVSthsLQnMRvJxdzh-NApiIOzkarqCcMpJuch6Tgb8cKKZ0WIUgnuFhTjBEQcHDVzKVTvN77djfMIX88P3QnswbBED1M2cytf8YE-HDNWhzSyZ0&t=634466635859336554")

This does not exist and causes a 404 error viewable in fiddler2. The style provided by WebResource.axd that is ignored does actually work

url("WebResource.axd?d=6f34yHv5y1TzMk-qXSedyUJ3gu_cuzFGdK186mb7ERzGXwRyXOrZcRZFvvBZU2BqM8REO42TLDNxTUpIk7koA_PsHFXVUovxk3l-H1Kep8esMtd22bWXhtBYtHaRWNs2Jzoa0ZCiZTx0uS1_usC6OqWvQQIRw2L4IsgFrEhgBCm7v1MX0&t=634466635859336554")

First of all I'm confused why both web resources are serving for the same content, and secondly how the telerik web resource can generate a reference for something that doesnt exist.

As an extra twist, the issue does not happen with everyone.

Hi All,

　

In the new 2011 Q2 controls the Checkbox in RadCombo is introduced.

　

I'm adding Items to the Control by Code, Always Select the first one, which cant be deselected

So on the Item_created i do the following:

if e.item.index = 0 then

e.item.checked = true

e.item.enabled = false

endif

　

which results in a greyed out Text, but still enabled Checkbox.
See attached picture

Kind regards Marco

Hi,

Given:
- I have an AjaxControlToolKit TabPanel.
- I have a radgrid in a tab with Master Table and Detail Table views. I am using Client hierarchy mode.
- I have having a dropdown in master table ItemTemplate. A selected index changed event is handled in code behind.
- I have a textbox in detailtable ItemTemplate. A javascript function is called on click of the textbox where I send textbox's Client ID. Inside the javascript function, I use document.getElementById() to get the DOM object of textbox.

Problem:
- When grid loads for the first time, everything works fine. I expand child items, click on texboxes and document.getElementById() gets me the textbox object.
- But when I click on dropdown, change the selected item and the grid loads back.
- Now when I open a child item and click on textbox, document.getElementById() throws a null reference error.
- I checked the viewsource, I was able to find the textox with id. But document.getElementById() is not able to locate it.

I believe this has something to do with Ajax and viewstate of DetailTable views but I dont know where the problem. Please help me pinpoint the issue and find a solution.
