                            string itemID = "1"; 
        
                            Repeater repPhoto = (Repeater)e.Item.FindControl("repPhoto"); 
        
                           DataTable ds = getMediaImages(itemID); 
        
                            repPhoto.DataSource = ds; 
        
                            repPhoto.DataBind(); 
        
                    } 
        
                }

Keeps throwing "Object reference not set to an instance of an object." I assume that it is not finding the nested repeater!

Please help

Enableviewstate=true?

I'm wondering what does this property do.
Can this property stores the entire data source into it?
Is this scenario possible where I'll bind the grid on 1st load and not relying on any viewstate in code behind to persist the data source of a grid?

one issue for attachment control

Hi:
When I use the attachement control in my latest control, it seems there is a bug for the attachment control. The control is showed in a pop-up page which is showed by the Telerik windows manager. Subsequently, if the cursor is put in the textbox of attachment and the corresponding Chinese Input Language is active, nothing will happen when the Select Button is clicked.
Can anyone tell me what is the problem for it? Thank you.

Accessing Edit Template Controls After Set Telerik.Web.UI.GridItem.Edit = true

Hello.
I have rad grid with templated columns (readonly and edit modes).
I set programmatically some row to edit mode base on my data on ItemDataBound event handler and then try to access control from row by its Id. I can't find control from EditTemplate but exist only from ItemTemplate

I explain on simple example. Here is a grid with templated column

    
            <telerik:RadGrid runat="server" ID="weldsGrid" AllowPaging="True" AllowSorting="True" 
        
                        PageSize="20" GridLines="None"> 
        
                        <MasterTableView AllowMultiColumnSorting="True" AutoGenerateColumns="False" EditMode="InPlace"> 
        
                            <Columns> 
        
            <telerik:GridTemplateColumn DataField="Welder" HeaderText="Welder"  
        
                                    SortExpression="Welder" UniqueName="Welder"> 
        
                                    <EditItemTemplate> 
        
                                        <asp:TextBox ID="WelderEdit" runat="server" Text='<%# Bind("Welder")%>' 
        
                                            ontextchanged="WelderTextBox_TextChanged" AutoPostBack="True" /> 
        
                                    </EditItemTemplate> 
        
                                    <ItemTemplate> 
        
                                        <asp:Literal ID="WelderRd" runat="server" Text='<%# Eval("Welder") %>' /> 
        
                                    </ItemTemplate> 
        
                                </telerik:GridTemplateColumn> 
        
            </Columns> 
        
                        </MasterTableView> 
        
                        <ClientSettings> 
        
                            <Selecting AllowRowSelect="True" /> 
        
                        </ClientSettings> 
        
                    </telerik:RadGrid>

ItemTemplate contains Literal control with Id = WelderRd and EditItemTemplate contains control WelderEdit

Here I set one of rows to edit mode when I get data from database.

    
            Private Sub weldsGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles weldsGrid.ItemDataBound 
        
                If (e.Item.ItemType = Telerik.Web.UI.GridItemType.Item OrElse _ 
        
                    e.Item.ItemType = Telerik.Web.UI.GridItemType.AlternatingItem) Then 
        
                  If (e.Item.ItemIndex > -1) Then 
        
                    Dim row = CType(CType(e.Item.DataItem, DataRowView).Row, DSBiasStep.BiasWeldRow) 
        
                    SetControlsVisibility(e.Item, row) 
        
                  End If 
        
                End If 
        
              End Sub 
        
            Private Sub SetControlsVisibility(ByVal row As GridItem, ByVal data As DSBiasStep.BiasWeldRow) 
        
                'set row to edit mode 
        
                row.Edit = data.IsActive 
        
                If Not data.IsIsAcceptedNull Then 
        
                  'even row in edit mode next row returns null 
        
                  Dim WelderControl= TryCast(row.FindControl("WelderEdit"), TextBox) 
        
                  If WelderControl Is Nothing Then 
        
                    ''''There is no reason to this but this is just example.  
        
                    'We always find a literal control even row is in edit mode         
        
                    WelderControl = TryCast(row.FindControl("WelderRd"), Literal) 
        
                  End If 
        
                  WelderControl.Enabled = CurrentUser.HasEditorRole 
        
                End If 
        
              End Sub

How can I get controls from EditItemTemplate after setting row to edit mode programmatically?

Setting Tabindex for GridButtonColumn

Hi,

i have a RadGrid with GridButtonColumns. The user needs to be able to navigate the buttons generated by the GridButtonColumns with the keyboard. There lies the problem: i can't set a TabIndex to the column and consequently the buttons are not included in keyboard navigation.
I can set a Tabindex to the Grid as a whole, but not to the columns. What can be done?

[Solved] LinkManager extension

Hi,

The LinkManager is now extended with the DocumentManager button, that works great.

I need the same functionality with the Image Manager.
I tried to copy and rework the DocumentManager code, but I am stuck on how to get the parameters back to the LinkManager form.

Is there any chance that this functionality can be added?
