RadPanelBar Expand is slow in Internet Explorer

In my asp page i have RadPanelbar which contains 2 list boxes and 1 RadTreeview and 1 Checklistbox. Below RadPanelBar i have RadGrid, which get re sized based on panel expand and collapse. I noticed that after binding listbox and treeview with database. Panel Expand takes time in internet explorer. Even UI looks merged in between transition.(Check ScreenShot, It slow such a way that i can take screen shot very easily :( )

Expand and collapse happening client side, so it's not doing trip to server during that operation, so why it takes time? It's all rendering time which is more in IE7?

Let me know any way i can make it faster? I already checked Optimizing article, which doesn't have anything specific to RadPanelBar or RadListBox

Thanks,

Configure HttpHandlerUrl for RadAsyncUpload

Hi,

I'm trying to configure the HttpHandlerUrl parameter for my RadAsyncUpload object.

I configureIt like this :

myAsyncUploader.HttpHandlerUrl = ("~/loggedin/ImageHandler.ashx?CarId=" + CarId + "&PartnerId=" + PartnerId);

The problem I have always an exception :

 http://vab/loggedin/ImageHandler.ashx?CarId=936&PartnerId=4?type=rau"

...Illegal characters in path
that's because of that "type=rau".



How can I pass my values from server side to that handler ?



How can I configure my RadAsyncUpload to avoid that "type=rau" ?



Thanks,

It is populated using data binding and all the columns show data...

Protected Sub RadGrid1_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

'Loads Data into the table

Dim ordlist As New dbrcOrdEst(Session("ConnectionString"))

Dim dt As DataTable = ordlist.ListOrderEstimates(498)

RadGrid1.DataSource = dt

End Sub

However what I want to do is take my textbox column, and return the values back into the database, however I can't get data out of the Textboxes, I know how to manipulate the data once I've got it, but I can't get it. This code does what I want on standard columns but not on textbox columns what am I missing

Protected Sub btnImport_Click(sender As Object, e As System.EventArgs) Handles btnImport.Click

For Each item As GridDataItem In RadGrid1.Items

Dim value As String

value = item.Cells(2).Text

	'DB Functionality

Next

End Sub

Thanks in advance for your help, Ryan
