Please remember without columns you can not add rows in datagrid. So first add columns then add row.

VB

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    If Me.txtcolumn.Text.Trim = "" Or Char.IsDigit(Me.txtcolumn.Text) = False Then
        MsgBox("Pls enter any digit!")
        Exit Sub
    ElseIf Me.txtcolumn.Text = "0" Then
        MsgBox("Pls enter any digit from 1 to 5")
        Exit Sub
    End If

    If Me.txtrow.Text.Trim = "" Or Char.IsDigit(Me.txtrow.Text) = False Then
        MsgBox("Pls enter any digit!")
        Exit Sub
    ElseIf Me.txtrow.Text = "0" Then
        MsgBox("Pls enter any digit from 1 to 5")
        Exit Sub
    End If

    Dim oCol, oRow As Integer

    While (oCol <> Val(Me.txtcolumn.Text))
        Me.DataGrid1.Columns.Add("Col" & oCol, oCol)
        oCol = oCol + 1
    End While
    oCol = 0

    If Me.DataGrid1.Columns.Count > 0 Then
        While (oRow <> Val(Me.txtrow.Text))
            Me.DataGrid1.Rows.Add()
            oRow = oRow + 1
        End While
    End If
    oRow = 0

End Sub
