    Hi there,
        I have a datatable that I am using as the source of my datagrid. The datagrid is a self referencing hierarchy. When I add a row to the datatable, it does not appear in the grid. If I add a second row, or click around in the grid it appears. It is as though the grid is not being repainted. I need to mention that this grid allows for drag and drop from another grid.

    Code under my add button:

    nCount += 1


    dr As DataRow


    dr = dtTable2.NewRow

    dr("Item Number") = nCount
    "ParentItem") = 0

    dr("Item Desc") = ""

    dr("Quantity") = 0

    dr("UOM") = ""

    dr("Vendor") = ""




    dgBOM.DataSource = dtTable2

    Hi Gary,

    You can use the Refresh method of GridViewTemplate to refresh the data in your self-reference scenario.


    If you continue to experience the issue, please send us a simple project with some part of your data to investigate the issue locally. Thank you for your cooperation.

    Please note that you have to open a new support ticket in order to be able to attach your files.
