Having a RadGrid in batch mode with Master and Details tables, when you add a new master record, you are not able to add a new detail record until you save the master record. 
This feature should be built in the RadGrid.

We are using version 2012.Q3 of Telerik, for the RadGrid control.

Once we updated to VS 2013 Update 2, we experienced a rendering problem on our development machines for all RadGrids on our site.

Upon further review we found out that this was due to the Browser Link feature in VS 2013. Browser Link appears to inject code between the development environment and the web server(s).

We were able to fix this upon finding an article pointing us towards the Browser Link feature. However it did take quite a while to figure out the issue, so we wanted to pass this along so that you could create a Knowledge Base article about this so that others can find the solution more easily and quickly.

Resolution:
Add the following item to the AppSettings section of the Web.config
<add key="vs:EnableBrowserLink" value="false" />

RadGrid cannot edit in IE8 under 2014Q2
javascript thows errors:
URI: http://localhost/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3azh-CN%3a8f393b2b-3315....

To fix the upper problem, we appyied 2014Q2SP1, however, in IE8, javascript thows new errors:
“sys is undefined” 
and the RadGrid does not display in web. But this is ok in debuging mode.

I want column width state maintain on postback. here with i am attaching may aspx page

My Sort order of records is persisting in normal radgrid but when i am using radgrid with grouping its not persisting.

The ragGrid during page load are as folllows.

Customer group Name        Customer Name      Sort Order
Group 1
                                              Very High                    1
                                                High                          2
                                               ABC                           3

and the filer for columns format are as follow

<telerik:GridBoundColumn HeaderText="Customer Name" FilterControlAltText="Filter column1 column"
                                    DataField="Name" UniqueName="Name" FilterControlWidth="150px" AutoPostBackOnFilter="true"
                                    HtmlEncode="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">
                                </telerik:GridBoundColumn>

And when i filter the grid on customer name with "high" word the grid shows results as follow

Customer group Name        Customer Name      Sort Order
Group 1
                                                  High                        2
                                              Very  High                   1
                                               
And i am needdatasource event then also this problem occurring so please provide me any solution.

grid line are not showing here with i am attaching the my aspx page and the current output page screen shot. this issue are randomly generated may be generate on first page load or on page scroll some lines visible or invisible. But grid line are always shown in IE8.

Hi Team,

Please go through the ticket.
http://www.telerik.com/account/support-tickets/view-ticket.aspx?threadid=821301

Here' there is javascript error on Filter click. We have attached the example in first thread.

The example contains a grid with a runtime header column addition. When the filters are on with Grid, clicking any of the filter icon to open "filter menu" causes a JavaScript error.

 If we skip the code to add "Runtime header column", there is no such error. But there is requirement of our client to have such header "Skip to Content" button in the header above filter.

Please see,
 - We are using a webcontrol, AECTelerikGrid as attached.
 - This should display "Skip to Content" in the header bar.
 - After this, click on any of the filters and this will result in JS error as attached.



Thanks,
Sunil

I am using a user control to insert and update the data found in the MasterViewTable as well as other detail items bound in child tables not included in the grid.  How does one pass the key value to the user control.  I am new to Telerik but it shouldn't be this difficult.

The latest update of Chrome browser Version 33.0.1750.117 breaks the radgrid vertical scrolling with these settings:

 <ClientSettings AllowColumnHide="True" AllowKeyboardNavigation="True">
                                    <Scrolling FrozenColumnsCount="1" UseStaticHeaders="True" AllowScroll="True" EnableVirtualScrollPaging="True" />
                                </ClientSettings>

Bind RadGrid client-side to a WCF Data Service, using a separate GetCount method. Then filter on column typing the value 12345 in the filter textbox. The result is that the value is not passed correctly to the web service.

This behaviour only occurs in Chrome Webbrowser if you select an item in the grid in the bottom area of a list which has of more than 20 elements.
If you start to drag the item, it appears far to low which means that it is sometimes not on the page anymore.
It is even possible to redo this with the telerik demo ( on http://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/rows/drag-and-drop/defaultcs.aspx)
if you use the pager some times.

GridBoundColumn has set ConvertEmptyStringToNull="false" but when calling InsertMethod, UpdateMethod the property binded to that GridBoundColumn is NULL.
TryUpdateModel then crashes

I am able to edit only the last row in a radgrid. When I select any other row ..it throws an error..
"There was a problem extracting DataKeyValues from the DataSource. Please ensure that DataKeyNames are specified correctly and all fields specified exist in the DataSource."
Though I have defined all the datakeyvalues it still throws me error.

Did any one faced this problem..If I m able to edit one row why not others..please suggest.

Thanks

In the following scenario it is not working.
1.	Grid populated with data.
2.	Filter applied on one of the columns in the grid. As a result data filtered correctly in the grid.
3.	For e.g 2nd column is moved to 5th column as vice versa.
4.	Again Filter applied on one of the columns in the grid.
5.	Grid data is not filtering as expected and column reorder that we did in point (3) is rolled back. (i.e., 5th column moved to 2nd column, vice versa)


Please help us in fixing this issue.

We are using the Radgrid and the problem is lines are sorted by the number in the textbox.

Somehow the text in the box gets left aligned and we need it to be right aligned even though in the code we have made right aligned. On mouse over the text starts getting right aligned but when page is reloaded it gets left aligned again.

We are using .net 4 and IE9.

I have RadGrid with RadButton as Checkbox inside it for selection.

This code: 
For Each item As GridItem In PrimaociGrid.MasterTableView.Items
            Dim cb As RadButton = CType(item.FindControl("PrimaPorukuCheckBox"), RadButton)
            cb.Checked = True
Next

worked in 2012.3.1016.40

With new 2013 q2 this is not working
I try 2013.2.709.40, same , not working 
There in no check in check box

when accessing column values in the client API (javascript),
if the row indicator column is included the column indexes are off by 1.
Behaving as if the row indicator column is not accounted for in the index scheme.

without this (additional) row, indexing is correct.

* I was just informed the indexing is also affected on the server side as well.

After the upgrade yesterday, when an event is fired using AjaxPanel or AjaxManager, the first column of the grid is showed reduced (I'm using a button to change the page view on a multipage, but the grid is on second page) then if I apply sorting on a column the grid show well, next change the page and wend return to the page of the grid this is showed bad.
The same error is doing when I have a grid and RadWindow is showed over a grid (in modal mode).
