Hi,

Please check the following code snippet to check CheckBoxes on header CheckBox check.

ASPX:

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
    <ItemTemplate>
        <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="ToggleRowSelection"
            AutoPostBack="True" />
    </ItemTemplate>
    <HeaderTemplate>
        <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState"
            AutoPostBack="True" />
    </HeaderTemplate>
</telerik:GridTemplateColumn>

C#:

protected void ToggleRowSelection(object sender, EventArgs e)
{
    bool checkHeader = true;
    foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
    {
        if (!(dataItem.FindControl("CheckBox1") as CheckBox).Checked)
        {
            checkHeader = false;
            break;
        }
    }
    GridHeaderItem headerItem = RadGrid1.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;
    (headerItem.FindControl("headerChkbox") as CheckBox).Checked = checkHeader;
}
protected void ToggleSelectedState(object sender, EventArgs e)
{
    CheckBox headerCheckBox = (sender as CheckBox);
    foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
    {
        (dataItem.FindControl("CheckBox1") as CheckBox).Checked = headerCheckBox.Checked;

    }
}

Thanks,
