Hello,

Are you using Unbound WebGrid? If yes, this is the limitation for unbound. You could not use FlyPostBackRequest in unbound scenario such as Refresh, Sorting, Add, Update, Delete, Filtering, Groung, etc.

Hello JammyMad,

What datasource? Is it XML? Can you send us a simple runable sample for that. You can see in our WebGrid sample about unbound sample. Also, XML datasource is also not supported like unbound scenario.

Hi,

// We are using .NET 4.0 Entity Framework.
// in the example below, searchResult is a DataTable with the bound columns for WGResults (Intersoft Web Grid)
// We dynamically add the column to WGResult and assign it a data source.

WGResults.DataSource = searchResults;
WGResults.DataBind();

<ISWebGrid:WebGrid ID="WGResults" runat="server" Height="500px" UseDefaultStyle="True"
      Width="600px" DefaultStyleMode="Win7">
      <LayoutSettings GridLines="Vertical" AllowColumnFreezing="Yes"
            AllowExport="Yes" AllowFilter="Yes" AllowSelectColumns="Yes"
            PagingMode="ClassicPaging" PagingSize="50" AllowSorting="Yes">
           <ClientSideEvents OnRowContextMenu="WebGrid_OnRowContextMenu"></ClientSideEvents>
       </LayoutSettings>
</ISWebGrid:WebGrid>

Thanks,

Hello,

I noticed that you bind your data in page load. This might be a problem. Please bind your data in InitializeDataSource event. 

e.g

protected void WebGrid1_InitializeDataSource(object sender, ISNet.WebUI.WebGrid.DataSourceEventArgs e)
{
     e.DataSource = searchResults;
}

Also, please specify DataKeyField in your RootTable.

Hello David,

It does not matter. We also have InitializeChildDataSource for child rows. You can also finalize in there.
