Hello Nipuna,

Thank you for writing.

From you code snippet I understand that you are having a RadGridView with a GridViewCommandColumn and you would like to add a new row in your grid on a click event in the command cell. Please check my code snippet below: 
Partial Public Class Form1
 
    Public Sub New()
        InitializeComponent()
 
        Me.BindGrid()
        Me.RadGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill
        AddHandler Me.RadGridView1.CommandCellClick, AddressOf RadGridView1_CommandCellClick
    End Sub
 
    Private Sub BindGrid()
        Dim decimalColumn As New GridViewDecimalColumn()
        decimalColumn.Name = "DecimalColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(decimalColumn)
 
        Dim textBoxColumn As New GridViewTextBoxColumn()
        textBoxColumn.Name = "TextBoxColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(textBoxColumn)
 
        Dim commandColumn As New GridViewCommandColumn()
        commandColumn.Name = "CommandColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(commandColumn)
 
        For i As Integer = 0 To 19
            Me.RadGridView1.Rows.Add(i, "Name " & i, "Add Row")
        Next
    End Sub
 
    Private Sub RadGridView1_CommandCellClick(sender As Object, e As EventArgs)
        'Me.RadGridView1.Rows.Add(20, "New Name", "Add Row")
        'Me.RadGridView1.Rows.AddNew()
        Me.RadGridView1.Rows.Insert(0, Me.RadGridView1.Rows.NewRow())
    End Sub
 
End Class

Additional information on how rows can be manipulated you can find in this section of our documentation: RadGridView | Rows.

I hope this help. Should you have further questions please do not hesitate to write back.
