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,

I have used AjaxLoading Panel, Now it is working only for Button click,
But it is not working for checkbox clicked.

Hi,

Anyone has an idea if this is a bug or need to set something?

I have a RadListView with RadDataPager.
When I click on the next icon of the pager on the bottom of my page, I want to see the top of the page, I verified the demo at below link  from telerik, the demo also shows the same,when you click on the next page icon, the page need to be loaded with data and top of the screen should appear.

http://demos.telerik.com/aspnet-ajax/listview/examples/paging/integratedpaging/defaultcs.aspx 

Right Now it loads the data and my screen will be same as before except with new data,as though nothing happened.

Data Bind List of ExpandoObject
Hi 

How I can override RadGrid to Data bind a list of ExpandoObjects.

Sample Code :

List<ExpandoObject> viewList = new List<ExpandoObject>();
for (int i = 0; i < 100; i++)
{
    dynamic view = new ExpandoObject();
    var p = view as IDictionary<String, object>;
    p["LatName"] = i * 2;
    p["Name"] = i;
    viewList.Add(view);
}
RadGrid1.DataSource = viewList;
RadGrid1.DataBind();
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" CellSpacing="0"
    GridLines="None">
    <MasterTableView>
        <Columns>
            <telerik:GridBoundColumn DataField="Name" FilterControlAltText="Filter column column"

Getting data from textboxs, within a radgrid
Hi,
I have a rad grid...
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateSelectColumn="True" CellSpacing="0"

                                </telerik:GridBoundColumn>
                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>

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

RadGrid using multiple datakeynames - doesnt work
Hi,

I am trying to use the following code to create a hierarchical grid.  It works all the way until the grid is expanded to the UserLocationVendorModel GridView (bolded code below).  This gridview (table) needs two keys (LocationID and VendorName) passed from the selection on the third level.  Could you tell me if I am missing something?  I have attached a screenshot of how the grid is not working on the last level.
 
VB.NET Code:

DefineGridStructure is called in the Page_Load event of the ASP.Net page.

 Private Sub DefineGridStructure()

        Dim RadGrid4 As RadGrid = New RadGrid
