I have 5 RadGrids on a page, registered with RadAjaxManager (AddAjaxSetting(grid, grid, loadingpanel)).

All grids use paging and hook the NeedDataSource() event. 

When I page through one grid, there is no full page refresh, the loading panel appears as expected and paging functions correctly. 

However, when I investigated the very slow paging I discovered that NeedDataSource (and infact all the lifecycle events) was firing on all 5 grids and not just the one that I was actually paging.

Is there any way that the RadAjaxManager could be refreshing all it's AjaxSettings regardless of which control is the trigger?

Thanks,

Hey,

I am having a problem with a RadDatePicker.  My picker is sitting inside a GridTemplateColumn under the EditItem section.  I am wanting to set the SelectedDate and the MaxDateRange from the codebehind but I cannot figure out how to access the control.  Can you please help me out??


Thanks,

Kyle

Hi all,
I have installed for Insert Command with code in ItemCommand event:
if (e.CommandName == RadGrid.InitInsertCommandName)
            {
                e.Canceled = true;
                e.Item.OwnerTableView.InsertItem();
                e.Item.OwnerTableView.IsItemInserted = true;
                GridEditableItem insertedItem = e.Item.OwnerTableView.GetInsertItem();
                String MyUserControlId = GridEditFormItem.EditFormUserControlID;
                UserControl userControl = insertedItem.FindControl(MyUserControlId) as UserControl;               
            }
this run well.

However, I don't know how to find my usercontrol when click Edit command. Please help me!

Thanks!

We have a RadGrid in which "CommandItemDisplay" is set to "top".  We would like to change the behavior of the "Add Record" function within this display.  Instead of the normal form for a person to input data with the insert and cancel links, we would like to popup a RadWindow that includes another RadGrid from which a user could select a record.

We have all the code for the popup and to return values to the primary RadGrid.  All we need is how to override the "Add Record" functionality of the CommandItemDisplay so that our method is called instead of the default.

Thanks!

Hi

I've noticed that since the release of Q2-2009, the buttons that are skinned don't look quite right. I'm using the Office 2007 skin, which usually gives the button text a blue colour, and centres the text in the button. But if you look at this screenshot -

You can see that the text is black, and the text is not centered (and perhaps the font size is a little bigger than it should be too?). I was just wondering if there was any way to fix this?
