Postback access to updated node text

Hi,
I am populating the nodes of a treeview control during the initla page load. I have set AllowNodeEditing="True". When a button on the page is clicked and the page is posted back I step through the nodes in the treeview control. I expect that the Text property of each node will be updated with the value typed in by the user. This does not seem to be the case. How do I get the data posted back to be updated with the user input?
Clayton.

Selecting data from multiple Grids

Hi,
I'm trying to build a method so that when i fire my select command from one grid it will take the data from the other grid aswell.

protected void gvSuppliers_ToCart(Object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        if (e.CommandName == "AddToCart")
        {
            //ProductGrid "gvDetails"
            _productName = Convert.ToString(gvDetails.MasterTableView.DataKeyValues[e.Item.ItemIndex]["ProductName"]);
            _productDescription = Convert.ToString(gvDetails.MasterTableView.DataKeyValues[e.Item.ItemIndex]["ProductDescription"]);
            _ean = Convert.ToInt32(gvDetails.MasterTableView.DataKeyValues[e.Item.ItemIndex]["EAN"]);

            //SupplierGrid "gvSuppliers"
            _supplierName = Convert.ToString(gvSuppliers.MasterTableView.DataKeyValues[e.Item.ItemIndex]["SupplierName"]);
            _price = Convert.ToDouble(gvSuppliers.MasterTableView.DataKeyValues[e.Item.ItemIndex]["Price"]);
            }
        }
    }

Now, i'm now quite sure if both grids should have the same "OnItemCommand" or if I could just call it from my SupplierGrid. Please help, need this done by tuesday :S

Atm i'm just getting:

[ArgumentException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.] System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) +2132776 System.Web.UI.Control.ValidateEvent(String uniqueID, String eventArgument) +108 System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +32 System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +7 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +11 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1746

which is not really the most helpful stack trace :(

ScriptManager & Rad controls

I had a solution running with Rad controls in .Net framework 2.0. As I've updated my solution to framework 3.5, I'm facing this error in my page with RadWindow:

The control with ID 'radWManager' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

But the ScriptManager is there before the "RadWManager", which is a RadWindowManager. What can be the case here?

ObjectDataSource TypedDS and UserControl

Hi!

I have created a simple Application to find out how to use the RadGrid with an UserControl as EditForm.

For this scenario i have created a typed DataSet / TableAdapter with Methods to fill the DS / Update / Delete and Insert Values and a ObjectDataSource which bounds to the Grid and points to the corresponding methods. Then i have created a usercontrol as the EditForm and configured the Grid to use this UserControl. In the ItemDataBound Event of the Grid I pass the values to my UserControl and everything is fine. But for the Update i have not figgured out how to pass the Values back to the Grid.

Can you help me on that?

Thx!

Tooltip Demo and SQLExpress

I installed the Q3 demos and I am getting a database error when I try to run the tooltip demo. I see in the web.config that SQLExpress is expected. Should this have been installed with the demo as part of the dev server?

On Edit open a new page

I have a web form with a radgrid on it and when the user clicks edit, I want them to be redirected to another page with the data from the selected record id filled in. I need help figuring out how pass the record id to the new page and then open the new page in the same window. I already have code in the Page_Load event of the new page that fills in data based on an ID that I have hardcoded for now. Here is my aspx page:

<%

@ Page Language="VB" MasterPageFile="~/Masters/PU89AdminMasterPage.master" AutoEventWireup="false" CodeFile="EditNews.aspx.vb" Inherits="Admin_EditNews" title="PU89 - Admin Area" %>

Slider causing content to shift when paging grid

I have a custom pager template in my RadGrid that incorporates a RadSlider control. Whenever the full screen can be viewed at one time the slider does not cause any problems when paging back and forth using the grid. Although, when the page is long and you scroll down the the bottom the content shifts each time I page back and forth. The entire page shifts upward. After stripping my page down I realized that the RadSlider was causing the problem. As soon as I delete it or make it invisible everything works as expected. It's odd that this only occurs when web browser vertical scrollbar is enabled and I am scrolled down to the bottom of the page.

Any ideas what might be causing the issue. I had the latest 3.5 sp1 framework installed.I'm also tried removing all the css styles to make sure it wasn't that. Please see my follow up posting below.

Thanks,
Levi
