Hello,

I created a composite control containing a RadGrid and several buttons for the user to configure the Grid (e.g. the columns).
The composite control also adds a loading panel which is used for ajaxifying the Grid.
I'm using the RadGrid on the page itself, and the other Grid is used in the FormTemplate of the first Grid. Everything works so far, but the LoadingPanel. It works fine for the first Grid, but doesn't for the Grid in the FormTemplate.

As I've seen in the markup, the loading panel is displayed, but it's height and width are both 0px. What could be the cause that the first RadGrid has it's LoadingPanel work correctly but the second one doesn't? What could be the cause for that behavior?

Thanks for your help!

Protected Sub myRadGrid_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemDataBound

If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then

Dim EditFormcmdItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

Two-way Declarative Binding to DataTable

Hi,

I am referring the below link,
http://www.telerik.com/help/aspnet-ajax/grid-binding-description-bind-method.html

two way binding at RadGrid, and I am currently migrating the GridView to RaidGrid, which GridView Application was using bind method to DataTable and save it DataBase, You may refer the below link,

http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-binding-to-datatable.aspx

and My question is,

1. ItemUpdated event was not fired, does it support? if not, any alternative solutions?
2. which event can be traced when data has been updated to the DataSource by using the above Two-way Declarative Binding approach?
3. Do we need to explicit update the value from RadGrid to DataSource (e.g DataTable)? for GridView, there is a function call gridView.UpdateRow to upate to DataSource.
4. As I have plenty of logic monitoring the dataTable dataChaning event for data validation, conditional data retrieving,calculation and so, it is painful if bind to DataTable is not working for GadGrid, Any Suggest for me?

Thanks.

Multiview Calendar - Hide some months?

I have a Multiview calendar which is set by default to show 1 year, in 4 columns and 3 rows.

I have 2 other DatePickers on the page that let the user pick a start and end date.

Based on the range selection in the 2 datepickers, I would like to hide unused months in the Multiview calendar. For instance, I show 12 months by default in Multiview, but if you select a range of April to August, then I would like to show the first row of 4, but then only 1 month calendar in row 2 - effectively hiding the last 7 months. All of this to be done dynamically on the server-side.

I can't seem to find a way to do this. Any one?
