Hi Telerik,

we are using single radwindow to show 3 to 4 lookups. each time it loads new page for each popup.
my problem here is,
when we load a page which having heavy content like radcombobox having 1000 values in it, window loads and closes successfully,
but when we try to open new popup(it also using same radwindow to show another page) now problem begins old page content still in radwindow so obviously it taking too much time to respond and load.
even worse is when we press backspace it going to previous loading page.

i don't want previously loaded content it should destroy that entire page when user closes or we closed from server side.

please do need full, thank you in advance.

Value must not be null for Controls and Behaviors

I have a RadComboBox in a PageView. When a user selects something from the combobox, I want to switch to a different PageView. However, I get the following error:

Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element

My AjaxManager is setup with the following AjaxSetting:

<telerik:AjaxSetting AjaxControlID="cboSchedules">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="tab" />

<telerik:AjaxUpdatedControl ControlID="mp" />

</UpdatedControls>

</telerik:AjaxSetting>

"mp" is the RadMultiPage. I think this is happening because the control that starts the Ajax request, which is "cboSchedules", is hidden the action of selecting an item.

First, am I right in this conclusion? Second, how do I get around it?

get_text() problem

Ok, so I started using this control, implemented some basic web service method to handle the updates of the notification control. This all works fine. The text sent from the WebService is set and the notification is displayed. However what I would like to do is display the notification only if the text sent from the web service is not string.Empty. So logic told me to use OnClientShowing or OnClientUpdated methods to check for the text of the notification and if it's not empty allow the control to show, if it's empty use the set_cancel(true) to cancel the showing. However, when i use sender.get_text() the value is always empty. What am I doing wrong here and how can I achieve what I'm trying to achieve here?

Regards,
Sasha.

Modifying color in Photoshop

Hi,

This is my first attempt at using this web tool but I couldnt get the desired effect/color.... Sometimes, it wasn't even changing the color... when fine tuning... example... i tried to select a white color and it was ignoring it... I had to change it in the css after it was generated.

Anyway my real problem is I tried to replicate a color theme from a screenshot I got from a graphic designer using the tool and although i choose picked up the color 1st attempt in using the toolfrom the dropper tool (used the hex codes ##AABBCC)... the final result was not as dark as the mock up i got.SO now I'm trying to see if I can modify the color directly on the generated output in photoshop...

I'm working on the RadWindow borders... In the zip i see png and gif files... which one of those is it radwindow using?
Can I just apply my color modification on the sprites and save it as is ?

Thanks

Radtreeview - expandchildnodes

Hi,

I have implemented the following code to retrieve information about childnodes for parentnodes:

Dim RadTree As New Telerik.Web.UI.RadTreeView

Dim temp As String = SessionWrapper.treeViewState
RadTree.LoadXml(temp)

                Dim i As Integer
                For i = 0 To RadTree.SelectedNode.Nodes.Count - 1
                    RadTree.SelectedNode.Nodes(i).Selected = True
                    If RadTree.SelectedNode.Nodes.Count > 0 Then
                        ListItems.Add(QuestionComparison)
                    End If
                    Exit For
                Next i

The problem is that the countervariabel only retrieves the total amount of childnodes when the selectednode is expanded!
Why is it like this? I want to retrieve the data without expanding the selectednode.

Besides this, the method for expandingchildnodes don't work on the serverside.
Why?

Default data has been deleted or is not loading in demo

Not sure if there is an issue, but I know this demo used to load with default data, it is no longer loading any data, figured I would give you a heads up. This demo:

Upload / Using RadAsyncUpload in an Ajaxified Grid
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandradasyncupload/defaultcs.aspx?product=upload

It looks as though the data has been removed.
