code has not been effect on form load event .

I have done coding of serial number in grid view in the load event of the form but when I am executing the form , The serial number code has not been shown in data grid view . but when same load event when I am calling from the button_Click event than Data grid view serial number is seen . why this happening ?

Load event of form :

private void Frm_View_Upload_Paper_Load(object sender, EventArgs e)

{

lan_id = que.language_ID();

DataSet ds = new DataSet();

string query = "Select * from VW_file_Upload_Download";

ds = que.execute_query_with_ds(query, connection);

if (ds.Tables[0].Rows.Count == 0)

{

DGV_View.DataSource = null;

}

else

{

DGV_View.DataSource = ds.Tables[0];

sr_no start..

int srno = 1;

for (int i = 0; i < DGV_View.Rows.Count; i++)

{

DGV_View.Rows[i].Cells["Sr_No"].Value = srno;

srno = srno + 1;

}

Button_Click Event :

private void button2_Click(object sender, EventArgs e)

{

Frm_View_Upload_Paper_Load(null, null);

}

Thank you all , I get the solution , instead of writing code in load event , i write in Databinding complete event of data grid view , hence now serial number is loading in first time only .

Try remove the FormLoad event andb re generate the FormLoad event.

Sometimes this happen becuase of debugger, try run the application without the debugger (Debug ->Start without debugging).

Hope this might help

Thank you @chetan for quick replying . Yah , coding has been executing but does not reflect in data grid view from load event or first time executing the form but when I am calling same load event from button click its reflect in the data grid view .

You have registered the event handler to the event of the form? Like following. Form1.Load += form_load
