c＃code is

gridview header checkbox coding-- -----



protected void CheckBox1_CheckedChanged（object sender，EventArgs e）

{

CheckBox ck ;

CheckBox ck1;

ck =（CheckBox）GridView1.HeaderRow.FindControl（CheckBox1）;

if（ck.Checked == true）

{

for（int i = 0;我< GridView1.Rows.Count; i ++）

{

ck1 =（CheckBox）GridView1.Rows [i] .FindControl（CheckBox2）;

ck1.Checked =真的;

}

}

其他

{

for（int i = 0; i< GridView1.Rows.Count; i ++）

{

ck1 =（CheckBox）GridView1.Rows [i] .FindControl（CheckBox2）;

ck1.Checked = false;

}

}
