How To Omit A Column From Row Select Postback?

Hi,

I am doing row selection to post back to the code behind with.

    
            <ClientSettings EnableRowHoverStyle="true"  EnablePostBackOnRowClick="true" >                                 
        
                        <Selecting AllowRowSelect="True" />                                                 
        
                    </ClientSettings>

The issue I have is in my left column I have a template checkbox column that I have the users to select. If they miss the checkbox just slightly then it causes the grid to postback. Is there a way to disable a column from causing a OnRowClickPostBack? I'm aware of how to get javascript events to fire on the row click, but the event args.set_cancel() is for only the client side and doesn't prevent the postback.

Thanks

Skip loading view state?

I have a RadGrid in which the contents and column settings are dictated by a dropdownlist.

When a dropdownlist item is selected, the grid's data and various configurable grid settings (like reordering, sorting, filtering, and column widths) are loaded from the database. The user can then manipulate various settings client-side and optionally save them out again.

When an Ajax postback occurs, like refreshing the grid, the settings are maintained by the viewstate as usual. For instance, if the user has changed the column width, that is maintained, no problem.

However, when the dropdownlist selection changes, causing a totally new set of data and settings to be loaded, any viewstate settings for the old data must be abandoned. The solution we tried was overriding LoadViewState to do nothing in this case, but we get a NullReferenceException from RadGrid.LoadClientState if a column is resized and then the dropdownlist selection is changed. If no columns have been resized, it works. Also, column-resizing seems to be the only setting for which the exception happens (that I've found so far).

Do you have any suggestions here, either a better way to clear the grid's viewstate on a new data load, or perhaps a workaround for the resizing issue?

Thanks very much,

Eve

WeekView - Customize Column

Problem:
If there are about 15 appointments at the same time and we need to show all the subject of appointments in weekview, we cannot achieve it. Please see the attached snapshot.

Is there anyway we can customize the column for weekview?

I've tried with ColumnWidth but it is affecting all the columns as well as the columns where there is no appointment. So I need the column to be wider where there are multiple appointments and can show the subject (in a readable form).

Please help us as this is very important for our client.

Thanks
Rajesh

Trying to access button in Panel Bar Item

I am trying to enable/disable a button within a RadPanelItem however the .findControl() method is returning null.

I can find a Telerik control placed right next to the button just fine. What the heck is going on here?

Here is the javascript I am using to get access to the controls.

var panel = $find("RadPanelBar1"); // PANEL

var pItem = panel.findItemByText("Record Details"); // PANEL ITEM

var lstBasis = pItem.findControl("lstBasis"); // Rad list box is found
var btnUM = pItem.findControl("btnUnfundedMandates"); // BUTTON IN THE PANEL ITEM IS NOT FOUND
