GridClientSelectColumn/CheckBoxColumn

[Joel]

I am not sure of the suggested method on how to accomplish this.  Any assistance would be greatly appreciated.

I have a grid bound to a boolean field.  If the item value is 1, I want he checkbox checked and read only (GridCheckBoxColumn would work here).  If the item value is 0, I want the checkbox enabled (GridCheckBoxColumn doesn't seem to work for this) and a postback when the user checks the box so I can update the database and rebind the two grids on the page.

In short, I want it so checks can never be removed, only added, and only one item checked per postback.  Grid is bound with NeedDataSource event.

Any suggestions?


Here is what I have now.  When it is done, I only want to have one column of checkboxes, the three below are all tests.

            <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="false"
                GridLines="None" Height="500" BorderWidth="0" AllowSorting="true" Style="outline: none"
                ShowGroupPanel="false" AllowPaging="true" AllowFilteringByColumn="false">
                <ClientSettings Scrolling-AllowScroll="True" Scrolling-UseStaticHeaders="true" Selecting-AllowRowSelect="true"
                    EnablePostBackOnRowClick="true"  EnableRowHoverStyle="true"
                    ClientEvents-OnRowSelected="RowSelected" >
                </ClientSettings>
                <MasterTableView TableLayout="Fixed"  GroupLoadMode="Client" DataKeyNames="job_id" >
                    <Columns>
                    <telerik:GridCheckBoxColumn DataField="isChecked" ReadOnly="false" HeaderText="My Job1" HeaderStyle-Width="60" UniqueName="mycheck1" ></telerik:GridCheckBoxColumn>
                    <telerik:GridClientSelectColumn HeaderText="My Job2"  HeaderStyle-Width="60" UniqueName="mycheck2"></telerik:GridClientSelectColumn>
                    <telerik:GridTemplateColumn HeaderText="Check/UnCheck"   UniqueName="TemplateColumn">
                          <EditItemTemplate>
                            <asp:CheckBox id="editChkBox" runat="server" AutoPostBack="true"
                             Checked='<%# Bind("ischecked") %>' Enabled="true">
                            </asp:CheckBox>
                          </EditItemTemplate>
                          <ItemTemplate>
                             <asp:CheckBox id="defaultChkBox" runat="server" Enabled="true"
                             Checked='<%# Eval("ischecked") %>'>
                           </asp:CheckBox>
                          </ItemTemplate>
                        </telerik:GridTemplateColumn>
                    <telerik:GridBoundColumn DataField="user_id" Headertext="userid" Visible="false"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="username" HeaderText="Username" HeaderStyle-Width="120px">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="Title" HeaderText="Title" >
                        </telerik:GridBoundColumn>
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>

Hello Joel,

Try out the following code using a GridCheckboxColumn to achieve the required sceanrio:

aspx:

<telerik:GridCheckBoxColumn DataField="Condition" UniqueName="CheckBoxColumn" HeaderText="CheckBox Column">
</telerik:GridCheckBoxColumn>

c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            CheckBox chk = (CheckBox)item["CheckBoxColumn"].Controls[0];
            chk.Enabled = !chk.Checked;
            chk.AutoPostBack = true;

        }
    }

Hope this helps..
Princy.
