Multiple controls with the same ID '_LightweightGroupPlaceHolder' were found

Hi Everyone,

I upgraded to ASP.NET AJAX 2016 Q1 today, and I've been receiving this error once in awhile. I'm not sure exactly what causes it.

I don't see it list any of my code. It does only occur on one page (so far). In this page I do two things related to grouping. In the 'DetailTableDataBind' event I group by a specific field:

e.DetailTableView.GroupByExpressions.Clear();
var gridGroupByExpression = new GridGroupByExpression();
gridGroupByExpression.GroupByFields.Add(new GridGroupByField { FieldName = "FIELD NAME", SortOrder = GridSortOrder.Descending });
gridGroupByExpression.SelectFields.Add(new GridGroupByField { FieldName = "FIELD NAME", HeaderText = "HEADER TEXT", Aggregate = GridAggregateFunction.Avg, FormatString = "{0:0}" });
gridGroupByExpression.SelectFields.Add(new GridGroupByField { FieldName = "FIELD NAME", HeaderText = "HEADER TEXT", Aggregate = GridAggregateFunction.Avg });
e.DetailTableView.GroupByExpressions.Add(gridGroupByExpression);

And in the 'GroupsChanging' event, I disable paging if at least one column is being grouped by:

(sender as RadGrid).AllowPaging = !(e.Action != GridGroupsChangingAction.Ungroup || e.TableView.GroupByExpressions.Count > 1);

Here's the full exception:

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Web.HttpException (0x80004005): Multiple controls with the same ID '_LightweightGroupPlaceHolder' were found. FindControl requires that controls have unique IDs.

Page with RadGrid crashes after adding new content

We have an ASP.NET forms app which makes use of the Telerik RadGrid. One particular page has some code that allows the user's search criteria to be remembered (not sure if this relevant).

Quite often when adding updated or new pages to the same folder the page with the RadGrid starts crashing even though this page hasn't been updated itself. It seems more likely to crash for people who were using the page when the other content changed as it doesn't normally affect everybody. The problem can normally be cleared up by recycling the application pool or resetting IIS (Which isn't always possible to do quickly)

We have recently moved to a new web server (Windows 2012 / IIS8). We had the problem on the old server too - I was hoping the server move would help but it hasnt. Can anyone offer any advice?

Part of the error is pasted below

A]GridSettingsCollection cannot be cast to [B]GridSettingsCollection. Type A originates from 'App_Code.tjhpcefj,

[Solved] GridDropDownColumn in EditMode

In my RadGrid, I am creating columns dynamically in code behind. One column is a GridDropDownColumn which is created as follows.

GridDropDownColumn columnn = new GridDropDownColumn();

TRG.MasterTableView.Columns.Add(columnn);

columnn.ListDataMember = "Department";

columnn.DataField = "Id";

columnn.ListTextField = "Name";

columnn.ListValueField = "Id";

columnn.DropDownControlType = GridDropDownColumnControlType.RadComboBox;

columnn.UniqueName = "Department";

columnn.HeaderText = "Department";

ListDataMemeber is set to corresponding table name in DataSet to which the RadGrid is bound.

Now, this column appears fine in as a Bound Column Display mode , and appears as a RadComboBox in Edit Mode, with correct values.

However, the issue is that the "ExtractValuesFromItem" in Radgrid_UpdateCommand doesn't get the value for this GridDropDownColumn.

protected void MyGrid_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

Hashtable NewData = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(NewData, (GridEditableItem)e.Item);

}



If there are total 12 columns in my RadGrid, then, there are 11 in "NewData" hashtable, and the GridDropDownColumn's value is missing.



What is the correct way to achieve this?

NeedDataSource not firing for NestedViewTemplate Grid initially

I have a very strange thing happening and really need some help. I am running the code below which includes a parent radgrid and a nested one but when the page first loads and I expand one of the top level grid items then the nestedviewtemplate grid (detailsGrid) doesn't have any data in it. When debugging this the detailsGrid_OnNeedDataSource event is not firing. However the parent grid (destinationCodesGrid) destinationCodesGrid_OnNeedDataSource method is firing immediately then the page renders with nothing in the nested grid. About 20 seconds later the detailsGrid_OnNeedDataSource event fires and the breakpoint hits but only after it is too late.

Here is an odd thing though if I do some other action in the grid that fires a postback first such as paging to the next page or clicking edit then after that point the destinationCodesGrid_OnNeedDataSource method fires immediately. Please advise!

Here is the code:

Can Radgrid reside in a <TD>?

Telerik Q1/2016 but this rendering behavior is the same in previous versions of Telerik.

I have RadGrid in a <TD colspan="3">. After postback the radgrid appears above the <table>.

Issue occurs with Chrome 47.0.2526.111 and IE 11 (when Edge mode is used).

It only works fine with content="IE=EmulateIE8".

VS2015 SP1, no other HTML syntax errors. Using AjaxManager.

RadDatePIcker MinDate

Hi.

I’ve been looking at your sample for validating a Raddatepicker:-

http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/validation/defaultcs.aspx

This is my scenario:

I have a raddatepicker and the mandate=”01/01/2009” this works great of course if I want to prompt the user that the date is incorrect, however I can still submit the form.

I then put a compare validator on the page and set that to Greater than or equal to “01/01/2009”, for some reason it won’t work.

Basically I want to prevent the user from submitting the form if the date is less than “01/01/2009” am I missing something?

Thanks

Karl

[Solved] RedCaptcha doesn't appear on mobile

I am using RedCaptcha on registration page and it works ok, but if i open this page from mobile device (or emulating it in browser) the redcaptcha image doesn't appear. If i open link from captcha src="" attribute in new tab i see the image.

You can see this issue by this url:

Maybe you have faced such issue earlier.
Any help will be appreciated
