Get checkbox from header

[Carlos Marchi]

Hi,

I've been problems in get checkbox from header of radgrid, and I dont know know to obtain this control. I need to access this control because When the user disable a check box from a row, then I need to access the checkbox all to set its checked property by false.

ex: checkboxSelectAll.checked = false;

Could Anybody help me, please?

Thak you for all attention,

Carlos

Hi Carlos,

I guess you are using following scenario.

aspx:

    <telerik:GridTemplateColumn UniqueName="CheckBox">
        <ItemTemplate>
            <asp:CheckBox ID="ItemCheckBox" runat="server" />
        </ItemTemplate>
        <HeaderTemplate>
            <asp:CheckBox ID="HeaderCheckBox" runat="server" />
        </HeaderTemplate>
    </telerik:GridTemplateColumn>

If so, the code shown below will help you to access the checkbox placed in headeritem.
cs:

    protected void Button1_Click(object sender, EventArgs e)
    {
        GridHeaderItem headerItem = (GridHeaderItem)RadGrid1.MasterTableView.GetItems(GridItemType.Header)[0];
        CheckBox headerCheckBox = (CheckBox)headerItem["CheckBox"].FindControl("HeaderCheckBox");
        headerCheckBox.Checked = true;
    }
