    I am programming in vb.net

    I want to get a value from a datagridview by checking if the value of a column is null and if it is null moving up one cell checking if that's null and so on.
    
If Not (dgvTestDataGrid.Item("myColumn", thisrow).Value) Is DBNull.Value Then

gColValue= (dgvTestDataGrid.Item("myColumn", thisrow).Value)

End If

    So that if the value in mycolumn is null I look up one cell , if that's null 2 cells etc.

    MM

    Add an Else condition to obtain the column index using the column name. Subtract one and then access the Column value using the index instead of the column name.
