I need only one checkbox as selected

[Mario]

Hello,
I have one Datafield from type boolean as checkbox in my grid:

<telerik:GridCheckBoxColumn DataField="TypeDefault" DataType="System.Boolean"
    FilterControlAltText="Filter TypeDefault column" HeaderText="Default"
    UniqueName="TypeDefault">
</telerik:GridCheckBoxColumn>

It may only one checkbox be selected in my grid. How can i  solve this?

Best regards

Hi Mario,

I am not quite sure about your requirement. If you want to check only one CheckBox, you can do it from code behind based on the condition  instead of binding it in aspx page.

ASPX:

<telerik:RadGrid ID="RadGrid2" runat="server">
  <MasterTableView DataKeyNames="OrderID">
     <Columns>
        <telerik:GridBoundColumn HeaderText="OrderID" DataField="OrderID" UniqueName="OrderID" />
        <telerik:GridCheckBoxColumn DataType="System.Boolean" FilterControlAltText="Filter TypeDefault column" HeaderText="Default" UniqueName="TypeDefault"></telerik:GridCheckBoxColumn>
     </Columns>
  </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem ditem = (GridDataItem)e.Item;
        CheckBox chk = (CheckBox)ditem["TypeDefault"].Controls[0];
        TableCell cell = (TableCell)ditem["OrderID"];
        string value = cell.Text;
        if (value == "1")
        {
            chk.Checked = true;
        }
    }
}

Please elaborate your requirement more if it doesn't help.


Thanks,
Shinu.
