Hi Everyone,

I am trying to use set_html function (besides other functions) but for some reason it stoped to work properly some weeks ago. Maybe related to jQuery version update, I don't know. This issue is freaking me out and I don't know how to solve it since it looks like something internal. Below you can see what I am saying, the error that I am facing.

Uncaught TypeError: Cannot read property 'selection' of undefined

RadGrid not refreshing

I have a grid with an form template for editing and adding. The grid also has a deletebutton column to delete rows. All the events are firing but the grid doesn't refresh after itemcommand completes its work after an insert, update or delete is performed on the database. I've stepped through the code and rebind() is being called. We bind to a list of objects.

This is the behavior I'm experiencing

Clicking Add
The edit form opens, I enter the data and press Save. The data saves, the form does not close. I then click Cancel, the form closes and the grid refreshes without a full postback,

Clicking the Edit icon in the row

The edit form opens, I modify the data and press Save. The data saves, the form does close (but only because I included Me.rgAccountGroupAuthorizations.MasterTableView.ClearEditItems() The grid does not refresh. If I click Cancel the form closes and the grid doesn't refresh.

Clicking the Delete icon in the row
After confirmation, the data is deleted but the grid doesn’t refresh.

I've isolated the code on its own page. The page doesn't have any ajax proxy (we use master pages) We would really prefer to use the form template feature rather than a custom edit page or user control.

Here is the markup and codebehind

RadWindow replaces parent in stead of showing pop-up

Hello,

I am using Telerik 2012 Q3 (.NET40) in a web application. The last few months, I am getting occasional bug reports about broken functionality. I have been able to trace this down to a radWindow not opening in a pop-up, but in fact replacing the complete page. Users claim they open the page by clicking the designated button and this is confirmed by the URL in the address bar, showing a query string like ?rwndrnd=0.8599367708780101. For them, the bug occurs sometimes.

So far, I have not been able to reproduce this issue. Users reporting it, all seem to be using Internet Explorer 11. The start of this bug may or may not be related to the upgrade of the web application, or the introduction of a newer version of Internet Explorer. It is hard to find out. I have seen a report in which a javascript error was in the Console, of some unrelated code.

Unfortunately, I cannot point to the actual web application, as it is non-public.

Has this behaviour been seen before and is there a solution to it?

I use the following code to open the radWindow:

function OpenForNewCase() {

var oManager = $find('<%= RadWindowManager1.ClientID %>');

var oWnd = oManager.GetWindowByName("wndNewCase");

oWnd.SetUrl('<%= ResolveClientUrl("Forms/NewCase.aspx") %>');

oWnd.Show();

RadGrid in TabStrip in Detail Table in RadGrid

Hi all,

I have a 'people' view listing users in a RadGrid, with an expand icon to show a detail table for each user. Inside the detail table I have a tabstrip separating areas for the user. My latest tab is 'documents' which needs to be dynamically generated server side, and contains a list of categorised (by tabs) list (in radgrids) of documents. My application is working ok, except when I open/expand another user's detail table. The documents tab renders correctly for the current open user only. All of the others just disappear. See screenshot attached for reference.

I am using the itemcommand event to check for the existence of the tabstrip tab(s) and if it exists I add the radgrid(s) (to the documents tabs), and if it does not I create the tab(s) and then add the radgrid(s).

Any ideas? Is there a better way to do this? I notice when I expand the details view the entire parent radgrid refreshes (loading panel). Is there a way, perhaps, just to refresh the open details view?

Thanks,
Alex.

How clear combobox at client-side

Good morning

I shall create a functionality for my users: at double click on RadComboBox (with the dropdown close) the combo is cleared.

ComboBoxs don't have client-side events as double click, right click, or others events that I can use.

PivotGrid Column name is missing letters

Hello Team,

When I return data set from db, it has a field named "MoreThan 20 chk is on here" which am trying to display on PivotGrid. But this field has more than 20 characters hence on pivot grid we can see column name as "MoreThan 20 chk is o", What changes am suppose to make so that it displays full name "MoreThan 20 chk is on here"

Refer attachments for more details.

Thanks,

BUG: RadGrid Width Affected by Scaling

Hi All,

I have a monitor running at 125% scaling (set in Windows Display settings). The radgrid width is calculated incorrectly. For some reason I always get a grid that is 503px wide (100% would be about 1500).

Both setting the scale to 100% and refreshing the page fixes it.

Moving the window to another monitor at 100% scaling and refreshing fixes it.

This looks to 100% be a bug in the way Telerik determines width when scaling is used.

Thanks,

Will

RadGrid - Resetting Grid with Persistent Manager

Hello

I have a form that has 7 grids. Each grid is being displayed within a separate RadPanel. Screenshot is attached.

We are using the Persistent Framework to store user settings. The Save and Load work great! The Reset works great if we are resetting all the grids.

My question is, Is it possible to Reset just one grid and allow all other grids to maintain their settings? Is there a function available that allows us to get very granular when resetting certain controls on a page?

Thanks

Tom
