gridview select all

piggrock

Use checkbox to make a gridview full selection box, but as soon as one page or sort the selected records disappears, I don't know how to solve this

To save the state, you have to use Session

How did you select all
1. If you want to keep it, you must register CheckBox
 CheckBox check = ((CheckBox) gvlDestination.theGridViewList.Rows [i] .Cells [0] .FindControl ("check"));
                    check.Checked = true;
                    if (check! = null)
                    {
                        checkstr + = string.Format ("; document.all ['{0}']. checked = true", check.ClientID);
                    }
                }
                                JS.ExecuteBlock (this, checkstr);

Use ViewState to turn pages

piggrock

<script runat = "server">
protected void CheckAll (object sender, EventArgs e)
  {
    CheckBox cbx = (CheckBox) sender;
    foreach (GridViewRow gvr in gvComUnion.Rows)
    {
      CheckBox ch = (CheckBox) gvr.FindControl ("ItemCheckBox");
      ch.Checked = cbx.Checked;
    }
  }
</ script>
I wrote that

This should be a problem

Try this   

 CheckBox cbx = (CheckBox) sender;
    string checkstr;
    foreach (GridViewRow gvr in gvComUnion.Rows)
    {
        CheckBox ch = (CheckBox) gvr.FindControl ("ItemCheckBox");
          //ch.Checked = cbx.Checked;
          if (ch! = null)
        {
            checkstr + = string.Format ("; document.all ['{0}']. checked = true", ch.ClientID);
        }
    }
    Page.RegisterStartupScript ("key1", string.Format ("<script> {0} </ script>", checkstr));

piggrock

protected void CheckAll (object sender, EventArgs e)
  {
      CheckBox cbx = (CheckBox) sender;
      string checkstr;
      foreach (GridViewRow gvr in gvComUnion.Rows)
      {
          CheckBox ch = (CheckBox) gvr.FindControl ("ItemCheckBox");
          //ch.Checked = cbx.Checked;
          if (ch! = null)
          {
              checkstr + = string.Format ("; document.all ['{0}']. checked = true", ch.ClientID);
          }
      }
      Page.RegisterStartupScript ("key1", string.Format ("<script> {0} </ script>", checkstr));
}
Is that right? Can not be done
