C#

protected void Page_Load(object sender, EventArgs e)
{
 if (Page.IsPostBack)
  {
     OnlyRead();
  }
}
private void Onlyread()
{
        int rowIndex = 0;
        SqlConnection conn = new SqlConnection(connectionString);
        StringBuilder sb = new StringBuilder(string.Empty);
 
        try
        {
            int count = GridView2.Rows.Count;
            for (int i = 0; i < count; i++)
            {
                TextBox box11 = (TextBox)GridView2.Rows[rowIndex].Cells[0].FindControl("TextBox11");
                TextBox box13 = (TextBox)GridView2.Rows[rowIndex].Cells[1].FindControl("TextBox13");
 
 
                rowIndex++;
                box11.ReadOnly = true;
                box13.ReadOnly = true;
               
 

            }

Solution 4

C#

protected void Page_Load(object sender, EventArgs e)
{
 if (Page.IsPostBack)
  {
     OnlyRead();
  }
}

and write your onlyread() method and just call it from btnclick.
protected void BtnSave_Click(object sender, EventArgs e)
  {
    OnlyRead();
  }

Solution 1

Just write :

C#

protected void Page_Load(object sender, EventArgs e)
{
   BtnSave_Click(null,null);
}

Note: But dear I can expect like this question if you are using C#. Learn more about C#

As per my understanding you want to call OnlyRead method from Button click event and Page load event. so can achieve two way either direct call only read method on page load event or call button click event.
