RowIndex always -1 using Unbound Grid

[Stephen Breytenbach]

Hi Julian,

as requested, here is the code for setting up my Master and Child and populating, unbound data (please let me know if you need more info)

I Really need to be able to access the RowIndex Value

thanks

Steve

Hi Julian,

would the correct approach be:

 

 

e.Row.Index

?
thanks

Hi Stephen,

I reviewed your code and all your previous posts. Please keep in mind that if you want to use the RowIndex of a row in hierarchy mode, you must get the Rowindex in context of its Parent row. Here is a sample of this:

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    int index = -1;
    if (e.Row.Parent != null)
    {
        index = e.Row.Parent.ChildRows.IndexOf(e.Row);
    }

    if (index < 0)
    {
        index = e.Row.ViewTemplate.ChildRows.IndexOf(e.Row);
    }

    if (index > -1 && e.Column.Name == "Barcode")
    {
        e.Cancel = true;
    }

    if (index > -1 && e.Column.Name == "Date")
    {
        e.Cancel = true;
    }
}

If you continue to experience the same issues, please send us a simple project with all API and events used to find the best solution for your scenario.

Thank you for your cooperation.
