Can you someone helps to show me how to disabled the grid if it's in the Detail Table of a Main Grid? I need to develop an App that required this feature. I know we need to use Grid Client API to work on it, but not sure how to write the javascript code.

I've include the picture showed the Grid in Detail Table of the master Grid. If user click on the checkbox on the Master Grid, Grid in Detail Table should be ENABLED.

Thank you.

centralizing loading sign

Hi,
I have a page consists of two grids. The bigger one is located in the center of screen, the other is smaller one which is placed at the rigth top corner. I have a template column including a button in bigger and centered grid. When it clicked some ajax code is executed. If I define
ajax setting as follows both of the grids are refreshing. But I only need smaller one to be refreshed. If I remove the the bigger one's config item from UpdatedControls section "Loading" sign is seems in the center of smaller grid. But I want the sign to be in the center og bigger grid. How can I do it? Refreshing two grids causes performance problem even there is no need.
Thank you,

Accessing Controls in RadListView not working

Under the RadListView you suggest the following:

RadControls for ASP.NET AJAX

Accessing controls in the LayoutTemplate

To get reference to a control in RadListView LayoutTemplate you can use its FindControl(controlId) method.

CopyC#

protected void RadListView1_PreRender(object sender, EventArgs e)
{
    Label lbl = RadListView1.FindControl("Label1") as Label;
}

I can't make it work. 
My code:
<telerik:RadListView ID="RadListView1" runat="server" AllowPaging="True"
    ItemPlaceholderID="PlaceHolder1" onitemcreated="RadListView1_ItemCreated"
    onprerender="RadListView1_PreRender" >
    <LayoutTemplate>
        <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
    </LayoutTemplate>
    <ItemTemplate>
        <div style="float: left;">
            <fieldset style="border: 0; width: 154px; height: 154px; margin: 5px 5px 5px 5px;">
                <div class="myClass" style="padding: 2px 2px 2px 2px; background: #eeeeee; text-align: center;">
                    <telerik:RadBinaryImage ID="RadBinaryImage1" runat="server" AutoAdjustImageControlSize="False"
                        CssClass="myClass" ImageUrl='<%# Eval("thumbUrl") %>' ResizeMode="Fit" AlternateText="Click to view preview"
                        ToolTip="Click to view preview" Width="150px" Height="150px" />
                </div>
            </fieldset>
            <div style="border: 0px; white-space: normal; width: 150px; margin: 5px 5px 5px 5px;
                padding: 2px 2px 2px 2px;">
                <asp:CheckBox ID="chkImage" runat="server" AutoPostBack="True" />
                <asp:HyperLink ID="lnkAsset" Target="_blank" NavigateUrl='javascript:void(0);' runat="server"><%# Eval("filename") %></asp:HyperLink>
                <asp:HiddenField ID="hiddenAssetId" Value='<%# Eval("id") %>' runat="server" />
            </div>
        </div>
    </ItemTemplate>
    <EmptyDataTemplate>
        No Assets Found
    </EmptyDataTemplate>
</telerik:RadListView>
Code behind:
protected void RadListView1_PreRender (object sender, EventArgs e)
{
    HyperLink lnkAsset = RadListView1.FindControl ("lnkAsset") as HyperLink;
    lnkAsset.Attributes.Add ("OnClick", "javascript:void(assetInfoPopUp(assetId));return false;");
}lnkAsset is null.

Some postbacks from dynamic controls are ignored

I'm using 2011_2_712 and have Uploaded a project here.

I'm using a RadTabStrip to dynamically load various User Controls. Events on these user controls sometimes take multiple firings for them to land on the event handlers.

To see this,
1. Put a breakpoint on the Select statement of rgOrders_ItemCommand()
2. Navigate to Default.aspx
3. Press "Select" for one of the customers. (The first one, Alfreds Futterkiste has orders)
4. Click the Orders tab.
5. Click Select for one of the orders.
Notice the postback is lost.

6. Press Select again and the postback is correct.

In my real project it takes 2 postbacks for one telerik control and 3 for another. Can anyone make sense of this or tell me what I'm doing wrong?

Thanks,
Dan

RadGrid ExcelML Export - Add a property to WorkSheetOptions

When exporting a Radgrid using ExcelML format, how can I set a property that is not defined in the WorkSheetOptionsElement? For example, within the WorkSheetOptions XML, there can be a property named Zoom that allows you to set the Zoom of the Worksheet. Can these be added using the InnerElements.Add Method and if so, how?

<WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel">
   <Print>
    <ValidPrinterInfo/>
    <VerticalResolution>0</VerticalResolution>
   </Print>
   <Zoom>75</Zoom>
   <Selected/>
   <Panes>
    <Pane>
     <Number>3</Number>
     <ActiveRow>18</ActiveRow>
     <ActiveCol>4</ActiveCol>
    </Pane>
   </Panes>
   <ProtectObjects>False</ProtectObjects>
   <ProtectScenarios>False</ProtectScenarios>
</WorksheetOptions>

Limit selectable items client side

Does not look like the RadListBox (SelectionMode="Multiple) has a "max # of allowable selected items" attribute, so how may I programmatically limit it client side?

I've got the following so far. But how do I basically say if the # of selectable items is greater than 5, then remove the last selected item?

Thanks! (fyi, I did an extensive search of the forums, and documentation but could not find something that shows me how to do this).
How do i set "item" to the last selected item of the listbox? sounds like
