Loop though a RadGrid with RadNumericTextbox

Hi,
I am looping through a RadGrid and getting the contents of a RadNumericTextbox through each iteration. Every radNumericTextbox appears to be empty even though I have numbers in each of them. I've tested a regular textbox control in my radgrid and the numbers do show up.

Here's the code:

    
            For Each item As GridDataItem In radGvProducts.Items  
        
                        If TypeOf (item) Is GridDataItem Then  
        
                            Dim txtQuantity As TextBox = CType(item.FindControl("txtQuantity"), TextBox)  
        
                            If txtQuantity.Text <> String.Empty Then  
        
                               'do something  
        
                            End If  
        
                            Dim radTxtQuantity As RadNumericTextBox = CType(item.FindControl("radTxtQuantity"), RadNumericTextBox)  
        
                            If radTxtQuantity.Text <> String.Empty Then  
        
                                Dim intQty As Integer = CInt(radTxtQuantity.Text.Trim)  
        
                                'Dim hdnShoppingCartID As HiddenField = CType(rptItem.FindControl("hdnShoppingCartID"), HiddenField)  
        
                                'Dim shoppingCartID As Integer = CInt(hdnShoppingCartID.Value)  
        
                                Dim hdnProductID As HiddenField = CType(item.FindControl("hdnProductID"), HiddenField)  
        
                                Dim prodID As Integer = CInt(hdnProductID.Value)  
        
                                Dim sc As New ShoppingCart(UserInstance.ContactID, prodID)  
        
                                'If UserInstance.ContactID > 0 Then  
        
                                sc.ContactID = UserInstance.ContactID  
        
                                'Else  
        
                                '    sc.UserID = DBNull.Value  
        
                                'End If  
        
                                sc.ProductID = prodID 
        
                                scsc.Quantity = sc.Quantity + intQty  
        
                                ShopCartCol.Add(sc)  
        
                                'sc.Save()  
        
                            End If  
        
                        End If  
        
                    Next

I check for radTxtQuantity.Text <> String.Empty before proceeding but it is always empty. Am I doing something wrong? It is never going into that If statement.
Thanks

How to lock down ImageManager paths?

My web site serves multiple customers where the content is customized depending on the domain name used to access the site. As such, I have a subfolder under the images folder for each customer. I can dynamically set the ImageManager paths in code using "~/images/" & CustID, but when the customer uses the ImageManager they always have access to the "images" folder. How can I lock them into their CustId folder under images? Is there a better approach?

Using TreeView and TabStrip in MOSS

Hi,

I've integrated both the TreeView and TabStrip controls (from the Telerik ASP.NET AJAX controls) into my MOSS master page and use two separate custom SharePoint lists as the data sources for these controls. This is all working fine.

My question is what is the best way to go about configuring these controls so that they remember which menu item (be it in the tree view or tab) that the user has selected? As at present always the first tab or tree view item is selected when the user navigates from page to page within SharePoint.

Many thanks.

NestedViewTemplate Not Rebinding with MasterTableView

I would think that either this is a stupid mistake I'm making, or someone else has at least had this problem, but I couldn't find any specific help in other posts, so here I go...

I have a NestedViewTemplate with a UserControl. I bind a couple of my UserControl properties to the row DataItem values. In my user control, there are a few buttons that change values on the grid (we'll say "Status" changes for this example). In the user control, if I update the "Status" of a row, I have to rebind the grid for the changes to show up. That all works fine, except when I call gridResumes.Rebind(), it shows the changes, but my NestedView is not showing anymore, the row is not expanded.

My solution was to have an event fire when you change a row using the NestedViewTemplate that tells me which row was changed. I then set "gridResumes.Items[updatedItemIndex].Expanded = true;" so that after the postback, the item is still expanded.

My problem is, calling Rebind() reloads the column data, but the NestedTableView is not bound to anything, the values within my user control are null. Why does Rebind() not rebind the NestedTableView? Do I have to call that manually after setting Expanded=true?

Required Field Validator for Upload in grid

The telerik grid example:
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/raduploadinajaxifiedgrid/defaultcs.aspx?product=upload

has the following:

    
                    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)  
        
                    {  
        
                        if (e.Item is GridEditableItem && e.Item.IsInEditMode)  
        
                        {  
        
                            GridBinaryImageColumnEditor editor = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("Upload") as GridBinaryImageColumnEditor;  
        
                            TableCell cell = (TableCell)editor.RadUploadControl.Parent;  
        
                            CustomValidator validator = new CustomValidator();  
        
                            validator.ErrorMessage = "Please select file to be uploaded";  
        
                            validator.ClientValidationFunction = "validateRadUpload";  
        
                            validator.Display = ValidatorDisplay.Dynamic;  
        
                            cell.Controls.Add(validator);  
        
                        }  
        
                    }

but it is using a specific column type.
how do I add a required field validator to the upload if I am doing this:

    
                                                    <telerik:gridtemplatecolumn uniquename="Upload" HeaderText="File Name">  
        
                                                        <itemtemplate> 
        
                                                            <asp:HyperLink ID="hlFile" runat="server" Target="_blank" /> 
        
                                                        </itemtemplate> 
        
                                                        <edititemtemplate> 
        
                                                            <telerik:radupload id="RadUpload1" runat="server" ControlObjectsVisibility="None" InitialFileInputsCount="1" /> 
        
                                                        </edititemtemplate> 
        
                                                    </telerik:gridtemplatecolumn>

I noticed this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/gridattachmentcolumn/defaultcs.aspx
what about validation on the attachment column?
