I have run into an issue here, i have 2 RadListBoxes on a page using the Transfer functionality. The first RadListBox is bound on a SelectedIndexChanged event of a RadComboBox using an XML file. I can transfer items to them with no issues. The issue I am having is that when i hit a submit button on the page and the page posts back the transferred items are duplicating in the second RadListBox. Has anyone seen this and overcome the issue? I am also using the RadAjaxManager on the page and I think this is where the issue is coming from, when I remove the RadAjaxManager from the page it all seems to work. Any ideas?

All server controls seems to be reloaded on the server side with a partial post back

We are using AjaxManager and have several child controls on one page. We noticed on the server-side every server control's Page_Load is being called. This is causing the page to load extremely slow.

We only need 4 child controls to be reloaded.

How can this be accomplished?

FieldEditor list isn't scrollable

I was trying out the code example using RadFilter in a RadWindow and I have over a hundred fields in my FieldEditor list. The problem is that when I select the dropdown, the list is larger than the screen and I'm unable to scroll through the list. Is there a fix for this or do I have to stick with the standard grid filtering? I want to be able to present my users with a concise grid, but with the ability to filter by more fields than displayed and only show the full resultset when they export to Excel.

contentWindow for radEditor document IFrame

Hello there

Can anybody resolve a confusion for me? I'm trying to run some Range manipulation, using a cross-browser compatible Javascript library (it is called 'rangy').

I know that the radEditor has its own client-side getSelection() function etc. The problem is that the 'rangy' library can only work with Selection objects that it creates itself, and that means it needs to be passed a reference to the Iframe object of the radEditor. Specifically though, it expects that the Iframe object in question should be in possession of a 'contentWindow' property. Is this usually just standard for Iframes that fill a window, as it seems to me from investigating the radEditor document DOM that the IFrame object returned by the radEditor's get_document() function does not have a value set for 'contentWindow'.

Am I missing something obvious here? Should the radEditor's Iframe document have a 'contentWindow' set? If this property can be set manually, how should I get a reference to the correct Window object?

Thanks if you can sort this confusion out for me!

Regards

Editor

Timeline View - Show Dates Under Header and Resources on the Right

As per the attached screenshot, does anyone know how to go from the Before to After? I know I could do ColumnHeaderDateFormat="M/d - H" to get the date in the row with the hours, but I really need the dates above.

I would like to add the lines in yellow and the dates. (The lines won't be yellow, I just did that for emphasis.)

All help is appreciated.

RadFilter not showing popup for GridDateTimeColumn

Hello

I have a RadGrid of Telerik 2012. I have a RadFilter associated with the Grid with the property FilterContainerID. My grid is dynamically created.

When I click the Add Expression button, it works fine and expression is seen. If the column is of type GridDateTimeColumn, then the calendar and time control is seen in expression but on clicking on it , no popups are there to select the filter value.

Also another problem is that on clicking the add expression button, the expression comes but it shows only the first column name in the list. If happens only when the first column of grid is that of an Integer type.

Any help will be highly appreciated.

Regards
Jiju.

Previous state child nodes

Hi,

When expanding a tree using for example two level:
- treenode 1
- treenode 1_1
- treenode 1_1_1
- treenode 1_2

When I collapse treenode 1 en expand again treenode 1, all childnodes will be opened exactly how they are opened. Is it possible to only open the first level of childnodes.
- treenode 1
- treenode 1_1
- treenode 1_2

Thanks for all reply.

OnClientNodePopulated is invoked too early

I'm trying implement something like this:
1. User clicks button that is placed somewhere on the page
2. RadTreeView expands some nodes (ServerSideCallback is used for nodes) to show some node
3. RadTreeView is scrolled to show this node (there are many nodes in the tree)

The problem is that OnClientNodePopulated is called before nodes are showed, so scrollIntoView method doesn't scroll to this node.
Is there any event that occurs after nodes are showed?

Browser: IE 8
