Select All pages in the gridview checkbox

You put a CheckBox at the Header of the column in the CheckBox in the GridView, and it indicates that all are selected (1. the CheckBox below is also checked automatically. 2. If you cancel any of the following checkboxes, the top one will be automatically canceled) and used as a flag for future use.
After dividing the page, the value cannot be obtained through the GridView. You can re-capture the data source based on the mark.

In net, how does one use a checkbox to select all the checkboxes in the gridview?

Protected void oncheckboxtransferchanging (object sender, EventArgs)
{
If (CheckBox1.Checked)
{
CheckBox CheckBox2;

For (int I = 0; I <GridView1.Rows. Count; I ++)
{
CheckBox CheckBox2 = (CheckBox) GridView1.Rows [I]. FindControls ("CheckBox2 ");
If (CheckBox2! = Null)
{
CheckBox2.Checked = false;
}

}
}
}
