Custom Checkbox Template In DataGrid

[Shawn]

I have a checkbox column in my datagrid like so:

<Columns>
        <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
            <HeaderTemplate>
                <asp:CheckBox ID="cl" onclick="return check_uncheck (this );" runat="server" />
            </HeaderTemplate>
            <ItemTemplate>
                <asp:CheckBox ID="chk_record" onclick="return check_uncheck (this );" runat="server" />
            </ItemTemplate>
        </telerik:GridTemplateColumn>
        <telerik:GridBoundColumn DataField="record"
            HeaderText="record" SortExpression="record"
            UniqueName="record" DataType="System.Int32" ReadOnly="True"
            Visible="False">
        </telerik:GridBoundColumn>

<script type="text/javascript">
    function check_uncheck(Val) {
        var ValChecked = Val.checked;
        var ValId = Val.id;
        var frm = document.forms[0];
        // Loop through all elements
        for (i = 0; i < frm.length; i++) {
            // Look for Header Template's Checkbox
            //As we have not other control other than checkbox we just check following statement
            if (this != null) {
                if (ValId.indexOf('cl') != -1) {
                    // Check if main checkbox is checked,
                    // then select or deselect datagrid checkboxes
                    if (ValChecked)
                        frm.elements[i].checked = true;
                    else
                        frm.elements[i].checked = false;
                }
                else if (ValId.indexOf('deleteRec') != -1) {
                    // Check if any of the checkboxes are not checked, and then uncheck top select all checkbox
                    if (frm.elements[i].checked == false)
                        frm.elements[1].checked = false;
                }
            } // if
        } // for
    } // function

</script>

I want the ability to run a number of different functions on this page which will use the data specified by the checkbox boolean.  I already have the grid using its row click selected event to load the nested view details, what I want now is the ability to get the row records associated with the checkboxes when something like a link button is clicked.

So how do I get the record integer value of all the checkboxes that are selected when my link button is clicked?

 Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click

'how do I loop through all of the checkboxes and get the row key (record) for all of them that are selected?

    End Sub

Hi Shawn,

Try the following code snippet.

VB:

Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
    For Each item As GridDataItem In RadGrid1.MasterTableView.Items
        Dim chk As CheckBox = DirectCast(item.FindControl("chk_record"), CheckBox)
        If chk.Checked Then
                'item["record"].Text will represent the value assosiated with checked Checkbox
            Response.Write(item("record").Text)
        End If
    Next
End Sub

Hope this helps :)

Thanks,
Shinu.
