As Dorababu said cause of postback your gridview got rebinded. Avoid the postback while binding gridview.

Put a breakpoint and check the ch is null or not if it is null then your checkbox din't got initialize in gridview. It might be here the id of checkbox is wrong.
CheckBox ch= (CheckBox)row.FindControl("cbRows");//this id

Hi
Ali

I am trying in this way

protected void btnMultipleRowDelete_Click(object sender, EventArgs e)
{
// Looping through all the rows in the GridView
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox ch= (CheckBox)row.FindControl("cbRows");

//Check if the checkbox is checked.
//value in the HtmlInputCheckBox's Value property is set as the //value of the delete command's parameter.
if (ch.Checked) /// Exception is occured here..
{
// Retreive the Employee ID
int employeeID = Convert.ToInt32(GridView1.DataKeys[row.RowIndex].Value);
// Pass the value of the selected Employye ID to the Delete //command.
SqlDataSource1.DeleteParameters["emp_id2"].DefaultValue = employeeID.ToString();
SqlDataSource1.Delete();
}
}
}

In your button evet handler, place this code:

dataGridView1.Rows.Remove(dataGridView1.CurrentRow);

it should work
