FrozenColumns, Sorting and Horizontal Scrolling

Team Telerik,

I've created a grid programatically and populate it with data. The first two columns are frozen, and I'm able to scroll left and right with the horizontal scroll bar. Everything looks wonderful. However, when I click on any column header to sort the data (Frozen, or Data columns); the horizontal scroll bar disappears and the columns off screen become inaccessible. Let me know if I've done anything wrong, below you will find my code. When I remove FrozenColumnsCount from the code, everything works fine. However... I do need the first two columns to be frozen.

Thanks,
Michael

Databound RadPanelBar - Controls dynamically added to child RadPanelItem

I have a RadPanelBar that is databound. Based on the values contained in the datasource, certain controls will be added to each child item. Controls such as dropdown, listbox, multiple labels, textboxes and buttons are added. On clicking a button or dropdown selectedindexchanged the controls disappear. I have tried creating dynamic controls in PanelBar_prerender event and they are created appropriately and displayed on the initial page_load,

On the subsequent pages, unless I do a PanelBar.DataBind, I get weird situation where the first child item disappears and the last child item repeats. On the next postback what was now the first child item will disappear and the last child item will now appear three times.

I have seen the example where panelitems are created in the page_load event. However, what I have is a databound PanelBar. I have seen references to "templateneeded" event, but none of the links seem to work to get to that article.

Can you provide an example of where controls are added dynamically to child panelitem when the PanelBar itself is databound and the dynamically created controls need to postback.

Thanks
Sumith

Default All Checkboxes 'True'

I have 2 List Boxes. One with State the other with City. The City Listbox has Checkboxes.
I am trying to find a way to have all the checkboxes 'checked' as the default when the page opens with a State Default selected.
For example ... When the page opens the State Selected Value is 'WA' and all the cities in Washington are displayed with checkboxes. Works fine.
But I want them displayed with Checkboxes 'Checked'

I have tried the collection method:

If Not Page.IsPostBack Then
    rlbAreas.SelectedValue = "F50"
    Dim collection As IList(Of RadListBoxItem) = rlbSubAreas.Items
    For Each item As RadListBoxItem In Collection
       item.Checked = True

    Next
End If

But the collection at this point returns 0 items. I tried rebinding the rlbSubAreas listbox but that didn't work either.

Anyone?

Dim empName As String = rdCBEmpList.SelectedItem.Text

lblMsg.Text = empName & " was added to the following group(s): "

' returns the list of items selected from the Source List

For Each item As RadListBoxItem In rlGroupListSource.SelectedItems

lblMsg.Text += item.Text & ", "

Couldnot Resize or Reposition the appointments on a scheduler atfer Grid Drop

Hai,

I have created a scheduler and Grid in which the grid drop is enabled.
When the Item is created on the drop of the grid the Appointments are not possible to "Resize or Repostion by Dragging".

Only these actions are permitted only if I do a page refresh or the postback.

What could be the reason.

Any help.

Countdown timer in Tooltip

Hello

I want to place a count down timer by using JavaScript in my tool tip, which is a .ascx.
In normal pages, the script works and the timer shows. But when showing in a tool tip, it doesn't work.

Is it an abnormal behavior?

Looking forward for the answer.

Thanks in advance

RadGrid and DetailGrid

I've got a RadGrid with detail tables in a search application.

Often times my users are looking at the detail tables and then change the search critieria.

At that point my code rebinds the grid and the detail tables the users were looking at before and no longer expanded. The users are not excited about having to expand out the detail tables again.

What's the best way to handle this situation. Is there an easy way to get the rows that are expanded before the bind and then programmatically expand them again?
