Multiple controls with the same ID 'ctl01' were found

Hi,

I'm getting this error when I enable paging in my EditableGrid:

Multiple controls with the same ID 'ctl01' were found. FindControl requires that controls have unique IDs.

Can't figure out what's happening...

Hi Filipe,

Where exactly are you enabling this paging...which grid, where? :-)

Hi Morten,

this is how I declared my grid:

     <dw:EditableGrid ID="GridDomains" runat="server" AllowSorting="True" AutoGenerateColumns="False"
            DataSourceID="LinqDataSourceDomains" EnableModelValidation="True" DataKeyNames="Id"
            CssClass="dwGrid" GridLines="None" PageSize="15" Width="100%" Visible="true"  
            OnRowDataBound="GridDomains_OnRowDataBound" OnRowUpdating="GridDomains_OnRowUpdating" AllowPaging="false">

It is within a content element and uses a master page. I use it in my module administration page.

When I change AllowPaging to true I get this error:

Multiple controls with the same ID 'ctl01' were found. FindControl requires that controls have unique IDs.

I appreciate any suggestion, thanks,

Pavel Volgarev

Hi Filipe,

Even though the EditableGrid control inherits from the standard GridView control (and therefore is meant to support all its features) it doesn't support some of the GridView's functionality such as paging. You can either implement a pager by yourself or use different control (for example, a GridView).

Here are some links that might be useful for you:
