GridClientSelectColumn

[Mike]

Hello,

Is there a way to link a GridClientSelectColumn to a DataSet?  I read through the documentation and the DataField property is not included, but I would like to be able to bind data with the column if possible.

I would use a GridCheckBoxColumn, however our users would like to be able to see which columns are selected for visualization, so I chose the GridClientSelectColumn.

If it is not possible, is there a way to use the GridCheckBoxColumn, but perform the same functionality as the GridClientSelectColumn?

Thank you,
Mike

use gridTemplateColumn

http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/SelectRowWithCheckBox/DefaultCS.aspx

As for binding, just add the checked = '<% Eval("bool")%>' into the Sample Code given by the demo.

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn" AllowFiltering = "false">
                            <HeaderTemplate>
<asp:CheckBox id="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True" runat="server"></asp:CheckBox>
                            </HeaderTemplate>
                            <ItemTemplate>
<asp:CheckBox id="CheckBox1" Checked='<%# Eval("Bool") %>' AutoPostBack="False" runat="server"></asp:CheckBox>
                            </ItemTemplate>
</telerik:GridTemplateColumn>

        Protected Sub ToggleRowSelection(ByVal sender As Object, ByVal e As EventArgs)
            CType(CType(sender, CheckBox).Parent.Parent, GridItem).Selected = CType(sender, CheckBox).Checked
        End Sub

        Protected Sub ToggleSelectedState(ByVal sender As Object, ByVal e As EventArgs)
            If (CType(sender, CheckBox)).Checked Then
                For Each dataItem As GridDataItem In RadGrid1.MasterTableView.Items
                    CType(dataItem.FindControl("CheckBox1"), CheckBox).Checked = True
                    dataItem.Selected = True
                Next
            Else
                For Each dataItem As GridDataItem In RadGrid1.MasterTableView.Items
                    CType(dataItem.FindControl("CheckBox1"), CheckBox).Checked = False
                    dataItem.Selected = False
                Next
            End If
        End Sub

Hi Mike,

You can also refer the following code library submission.

Thanks

Thank you both for the examples.  I like solution 2 because I want to avoid using a postback due to the fact I will be working with massive amounts of data.

My only other question is in the client side function CheckAll() is there a way to have it highlight the item when it is checked.

Basically if a dataitem is checked I would like it to be highlighted as well.

Thank you!
Mike
