Postback problem in custom advanced form

Hi!
I'm using the radscheduler with a custom advanced form.
Both the advanced form and the page containing it have EnableViewState to true but I'm still having post back issues.
When a control in the advanced form fires a postback, all data binded to the advanced form is cleared and the state of the controls are reset.

How do you prevent this?
thanks!

Add target="_Blank" to NavigateURL

Hello,

I have the RadImageGallery implemented using the following:

<telerik:RadImageGallery ID="ImageGallery" RenderMode="Auto" runat="server" LoopItems="true" ShowLoadingPanel="true" AllowPaging="false" DisplayAreaMode="Image" OnNeedDataSource="ImageGallery_NeedDataSource" DataTitleField="ImageTitle" DataDescriptionField="ImageDescription" DataImageField="ImageURL"></telerik:RadImageGallery>

the Code behind is like this:

Protected Sub ImageGallery_ItemDataBound(sender As Object, e As ImageGalleryItemEventArgs) Handles ImageGallery.ItemDataBound Dim item As ImageGalleryItem = TryCast(e.Item, ImageGalleryItem)

Dim db As New DBCorrDefense.DBDCDataContext()

For Each item In ImageGallery.Items

Dim EmData = db.CDSP_Get_URLByImageTitle(item.Title).FirstOrDefault

If EmData Is Nothing Then

Else

item.NavigateUrl = EmData.URL

End If

Next

db.Dispose()

db = Nothing

End Sub

Protected Sub ImageGallery_NeedDataSource(sender As Object, e As Telerik.Web.UI.ImageGalleryNeedDataSourceEventArgs) Handles ImageGallery.NeedDataSource

Dim db As New DBCorrDefense.DBDCDataContext()

ImageGallery.DataSource = db.CDSP_Get_AllSlides()

End Sub

How is it possible to allow the NavigateURL to open in a new blank page when i click on the ImageItem? currently it is opening in the same page

Thanks

Hide RadGrid data and header at runtime

Hello, I am populating a radgrid on the NeedDatasource event, the columns are AutoGenerated, I require that some columns be hidden at runtime which I am doing on the ItemDataBound Event using e.Item.Cells[2].Visible = false;. THis works great however the problem is that the associated column header is not being hidden so I end up with 4 data columns and 8 column headers. I'm I using the wrong event or wrong property to hide the columns.

Thanks

Looking for RadGrid pager element string resource name

I don't seem to be able to find the appropriate string resouce name for the RadGrid's paging ComboBox's tool tip.

What is the corresponding string resource name for this item?

Is there a list of available string resource names? Or is there a method to compute the string resouce name from the rendered RadGrid control?

How can I reset Grid sorting?

I have the RadGrid within an RadAjaxPanel, along with some other controls to control which DataTable is to be displayed.

When I'm first sorting the Grid and then going to select another DataTable to display in the Grid, data binding fails with an error message telling me that the Grid cannot find the sorting column I selected for the first DataTable.

How can I reset the Grid's sorting/paging setting so it will start anew with a new DataTable assigned?

Removing Managers from RadEditor

I am wondering if there is a way to remove the DocumentManager, ImageManager etc from the RadEditor so that none of the extra javascript for those features is loaded. In this particular spot I am using RadEditor it is for fairly basic formatting and none of the advanced features are necessary. I am not having any particular problem, just looking for any ways to streamline and improve performance in general.
