RadDateTimePicker SelectedDateChanged bad data

I think I'm being stupid on this one but I need to ask.

I have a UserControl with a RadDateTimePicker and the SelectedDateChanged event set to get handled in server codebehind. When the date or time are changed by the user, the event is fired, but neither the 'sender' nor the arguments object have all of the data.

The sender is the control but the SelectedDate on the sender is null. Sometimes the sender FocusedDate has the new value. In the SelectedDateChangedEventArgs value, the OldDate and NewDate are null.

The events being fired are in this order on PostBack:
Page_Load in the parent container, where I invoke setup methods in all user controls to set their initial values.
Page_Load for all user controls.
SelectedDateChanged
Page_LoadComplete for parent
Page_LoadComplete for each UC.
Then in Page_PreRender I get the control data and save it to SessionState so that I can refresh it the next time in.

I felt a need to go through that because controls initially weren't refreshing after postback.

I'm wondering if the sender or arguments are getting trashed prior to the SelectedDateChanged event because I load from state before that event fires. But that doesn't make sense to me.

Any ideas?
Thank you VERY much.

refresh parent on AJAX postback is working only the first time

Using the suggestions on this forum, I've created a radwindow which refreshes the parent page via AJAX postback.

On the parent page, from code behind, I rebind a control that was updated in the radwindow like this:

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
    {
        FormView1.DataBind();
    }

FormView1 is an an update panel and it works perfectly the first time. However, after I reopen the radwindow before a full postback, it does not call the AJAX function again. I tried setting the radwindow with DestroyOnClose using both true and false and it still doesn't work.

Any suggestions?

Hierarchy DataSource Issue

Hi All,

I have an entirely code-behind C# Radgrid solution, living in SharePoint. I have implemented a detail table within my mastertable and the hierarchy (parent-child) functionality of the grid works well. However, this is only when I use RadGrid.DataSource = SQLDataSource. Doing this breaks column sorting though.

Changing my code to RadGrid.DataSourceID = SQLDataSource.ID allows me to sort the columns but breaks the hierarchy. Does anyone have any suggestions on how to fix this?

Thanks,
Mark

Radgrid editform template adds remaining table to form

I have a radgrid on an aspx page and have set up an edit form template to edit one of the columns. The problem is when I click on the button to edit the column, instead of getting only the tables in the edit form I get those tables plus the remaining radgrid data under it. I have tried it as a modal popup, inline and all other possibilities with the same results each time. I've attached a couple of jpegs to show what I mean. Any help is appreciated.
