hi,

i have tried this code by creating a dummy page... its working great..

protected void gvPkgcbndate_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton lnk = new LinkButton();
lbtn.Text = "lnk";
lbtn.Click += new EventHandler(lnk_Click);
e.Row.Cells[0].Controls.Add(lnk);
}
}

Hi,

I assume that your button also displaying correctly but event is not firing.

When you are doing any postback(any button click or any server side event fired) then page is deleting your link button event handler. So please try to bind the event after each postback.
static bool enable = false;
protected void Page_Load(object sender, EventArgs e)
{
   if (!IsPostBack)
   {
      // This is your Link button display
      DynamicButton();
   }
   else if(enable)
   {
      // This is your Link button display
      DynamicButton();
   }
}

protected void gvPkgcbndate_DataBound(object sender, EventArgs e)
{
LinkButton lnk = new LinkButton();
lnk.ID = "lnk";
lnk.Text = "click here";
lnk.Click += new System.EventHandler(lnk_Click);

enable = true;
}
