Question

I came up with following code that adds number of columns based on user input in textbox1, but how to add names to these columns? (Columns added should have names like, A1,A2,A3…….on the top most row)

Dim t As Integer
t = Val(TextBox1.Text)
For i = 1 To t
    Form2.DataGridView1.ColumnCount = i
Next

Also can we freeze specific cells in a datagridview i.e. cells which user cannot edit?

Answer 1

Try this

DataGridView1.Columns(i).Name = String.Format("A{0}", i)

Once you have access to Columns(i) you can view available properties from the intellisense

DataGridView1.Columns(0).Frozen = True;
