I am trying to retrieve value of the selected item in GridDropDownColumn on RadGrid1_UpdateCommand event. I get

Error: "Cannot find a cell bound to column name 'FormID'". I am giving all the code, but the issue is in RadGrid1_UpdateCommand when it tries to get the FormID.

I have a Pivot grid with two filter. I am able to save and load the saved filter settings from the xml file in App_Data. But now I need some modifications to be made.

One of the Filters is a DataRange field which holds the Release dates and I want the Latest DateRange to be selected by default on load. Since this will require the saved xml file to be updated with new values. 

I will have the latest Date in my dataset. is there a way to update the saved xml file with a value from the Dataset before loading the pivot with default settings.

I am using a RadGrid, on load some of the columns are hidden. I have a button which should unhide those columns when clicked and the text should change to Hide. On click of the same button again the columns should hide. I am able to hide the columns successfully  but unable to figure out how to unhide.

Here is the code:

<input type="button" id ="toggle" value = "Hide" onclick="HideUnhide()" class="=tdText" /></>

function HideUnhide() {

                var grid = $find("<%= RadGrid1.ClientID %>");
                    grid.get_masterTableView().hideColumn(8);
                    grid.get_masterTableView().hideColumn(9);
                    grid.get_masterTableView().hideColumn(10);
                }

I am trying to include condition in the function where I can change the text from Unhide to Hide and depending on the text Unhide the columns in the else part but that doesn't seem to work.

Currently this code can only hide unhidden columns. 

Please help.

I have several grids that won't transfer tool tips and other column "decorations" like left / right justification when a column is moved interactively by the user. I believe I have found via google search this was a know problem in older versions. Is there a way I can tell which versions have the problem?

We are running 2014.3

In my current program I have 2 RadComboBoxes within col-md-4 divs. 

The labels of these boxes are vertically out of line both with their drop down boxes and with the RadTextBox on the same line (in another col-md-4 div).

Is there a way yet to fix this, either through settings or CSS? 

Most of the references I've found so far seem pretty old.  (I'm currently running the latest version of the Telerik Asp.Net for Ajax controls.)

Hello,

Can exist dynamically  generated RadGrid with static RadGrid on the same aspx webform page? 

The situation:

I have put two radgrids on the same page (one is created in Page_Init() another static). Every thing worked fine until I decided to add GridTemplateColumn to dynamically created grid (using IBindableTemplate and ITemplate). Then I started to get  error:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidOperationException: Stack empty.

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

I get this error when I try to edit or add new record on static RadGrid. 

The dynamically created RadGrid works without problem.

I have even created new empty project to test this and the problem remains.

Any Ideas?

Thanks

Darius
