    Datagridview Header

    Hi,

    On my datagridview cellmouseclick event I have this code:

    Code:
    Index = e.RowIndex
            Dim selectedRow As DataGridViewRow
            selectedRow = DgTenantDetails.Rows(index)
    Now, at runtime when I click any cell on the header I receive the error message:

    Code:
    System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection.
    Parameter name: index'
    What is wrong?

    Thank you!

    Re: Datagridview Header

    Two things:
    You are finding the RowIndex, but you click the Column header?
    The first code snippet will work perfect when you click inside the row inside the grid, hence the message.
    Second thing: have a look into the ColumnHeaderMouseClick event to capture column headr events
