How to give title in RowHeaders datagridview in VB.NET?
by that I mean circled the color in yellow in the screenshot below.
There's a property TopLeftHeaderCell for that cell. You can use it and set the Value

DataGridView1.TopLeftHeaderCell.Value = "Index"
You can also set the other properties of the cell, like its alignment, for example:
DataGridView1.TopLeftHeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter
