How to retrieve updated data in RadGrid

Can someone show me how to retrieve data back from RadGrid row. This should not be a night-mare, but it turn out to be.

And looks like we have no support here from Telerik, after we bought the products.

Thanks.

MasterTableView Header changed when expand the details

I set the mastertableview header in ItemDataBound for both Master and Detail TableView. But when I click to expand the details, the mastertableview header changed back to the field name. And when I click the other expand button, the first details header also changed to fieldname. Where should I put the headertext code in my code behind? I am using vb.net.

Tks,

Recommendation for the following use case

I would like to get your suggestion to handle the following use case:

The form is based on the ASP:Wizard for ordering map prints
The user selects maps from a database, the selected maps are added to a cart stored as datatable in the session variables. The selected maps are shown in a RadGrid with the requested quantities.
In the next wizard step: For those maps with more than certain copies, the user can upload overlay information to be printed on the maps. For each line in the RadGrid shown in this step an AsyncUpload control is displayed.
Only after the user completes all of the required information such as delivery and payment the cart will be stored as a record in the database.

My questions:

What will be the best practice to handle the files being upload until the cart is suppose to be stored in the database?
How to avoid multiple uploads for the same item? Should I worry about it?
How can I clear files when the purchase was not completed?

Thanks,
Yoram

Pass label text as parameter to radopen

Let me see if I can explain this....

Using a MasterPage...

I have a RadGridView with ViewEditForm. When the form opens I have a RadButton that when pressed should open a RadWindow to display a page of additional details related to the main record.I need to be able to pass a parameter in so that the value can be added to the querystring of the URL. I have a hardcoded version of it working but I need to know how I can grab the parameter off of the ViewEditForm or from the grid row. The value is available from the text of a label (Label1) within the form where the button resides. This is the hardcoded version that works - I need to replace the 9953 in the onClientClicked portion with the dynamically retrieved value.

The aspx page:

<telerik:RadButton ID="btnTitleDetails" runat="server"

EnableEmbeddedSkins="False" Skin="Metro_BLT" Text="Title Details"

onClientClicked="function(sender, args){openRadWin(sender, args, '9953');}"

AutoPostBack="false" />

The Javascript from the masterpage:

<script type="text/javascript">

function openRadWin(sender, args, propId) {

var url = location.href;

var baseURL = url.substring(0, url.indexOf('/', 14));

radopen(baseURL + "/TitleDetail.aspx?&propid=" + propId, "RadWindow1");

</script>

Folks, Using RadControls for ASP.NET AJAX Q2 2012 SP1 with VS 2010.

My Radgrid has approximately 65000 rows; uses LinqDataSource. also I have a external Panel (Panelotherinfo) to Navigate to other forms.

Need to hide column in nested grid

I have a radgrid, which has a nested template view with another grid in the nested view. I have a column that contains a hyperlink, which i only want displayed if the user is in a particular role. I have the role part down, but my problem is I cannot access the grid through the vb.net code behind window.

I try me.gridSchedule, but it is not in the list.

How can I hide this column programmatically?

Thanks...Brian

Problem with Tooltipified RadGrid Demo in VB

I have copied the source code from the VB version of the demo which demonstrates how to pop up a custom control with database content.

I also duplicated the database tables.

I can get 95% of the way, and then I find an error that makes no sense to me. The attached screen shot indicates a problem with creating an instance of the custom control as "ProductDetailsVB" not defined. This is actually detected in VS2010, but I ran the code to create a better error description.

I have confirmed that the ASCX control works with static placement on another page. In order to run the demo code, I have commented out two lines "Dim Details as ProductDetailsVB..." and "details.ProductID. When I do this I get the appropriate behavior for the popup control, minus actual database content because it is not receiving the ProductID.

I have created the control as "ProductDetailsVB.ascx" to match the source code. But I do note that the online demo references "ProductDetailsCS.ascx" which would not be appropriate for a VB programmer such as myself.

This is my first custom control, and I have no clues as to the error, and am doubly confused over the reference to CS in a VB demo.

Partial Class pop2

Inherits System.Web.UI.Page

Protected Sub OnAjaxUpdate(sender As Object, args As ToolTipUpdateEventArgs)

Me.UpdateToolTip(args.Value, args.UpdatePanel)

End Sub

Private Sub UpdateToolTip(elementID As String, panel As UpdatePanel)

Dim ctrl As Control = Page.LoadControl("ProductDetailsvb.ascx")

panel.ContentTemplateContainer.Controls.Add(ctrl)

Dim details As ProductDetailsVB = DirectCast(ctrl, ProductDetailsVB)

details.ProductID = elementID

End Sub

'Add the button (target) id to the tooltip manager

Me.RadToolTipManager1.TargetControls.Add(target.ClientID, (TryCast(e.Item, GridDataItem)).GetDataKeyValue("ProductID").ToString(), True)

RadMenu using AJAX during MouseOvers?

I have a simple RadMenu, with several RadMenuItem's. After the page loads, and sits there for a while, it seems that when I mouse over when of the menu items, it is doing some type of AJAX postback to the server (e.g. it can hang or delay showing the highlighted button). Is this correct ... is it doing AJAX calls for just displaying simple menu items? Is there a way to disable any/all AJAX stuff for the menu ... I just want to use it for simple menus with an onClick javascript handler.
Thanks
