Hi Guillermo,

     Yes, if we use Classic Paging in the WebGrid,  we cannot create the new cellTemplate in PrepareDataBinding since the WebGrid's life cycle only ignites the function once in the beginning. To have  the label appears in the next page of classic paging, we need to set it on InitializeLayout. You can remove the code in PrepareDataBinding and put these following code on your InitializeLayOut. So that, the layout will be re-initialize after we go to the next page. Here is the snippet:

if (WebGrid1.RootTable.Columns.GetNamedItem("test") == null)
        {
            WebGridColumn newColumn = new ISNet.WebUI.WebGrid.WebGridColumn();
            newColumn.ColumnType = ISNet.WebUI.WebGrid.ColumnType.Template;
            newColumn.CellTemplate = new cellTemplate();
            newColumn.Name = "test";
            newColumn.Width = 300;
            newColumn.Caption = "Templated Column";
            WebGrid1.RootTable.Columns.Add(newColumn);
        }
        else
        {
            WebGrid1.RootTable.Columns.GetNamedItem("test").CellTemplate = new cellTemplate();
        }   
            

Thanks Andi, effectively I have to create the column onInitializeLayout and don't check for the postback to make it persist while paging.

Hi Guillermo,

     Yes it is. Glad to hear that it solves your problem. Please do not hesitate to ask if you have any other questions. Thank you.
