    Here i have three methods are selectRoles,selectRoleFeatures and Assign-UnassginRoleFeatures which is allocated to particular user.
how to implement this which kind of grid suitable for this and what is code to aspx and aspx.cs pages..

My aspx page code is

 <telerik:RadGrid ID="Roles" runat="server" AutoGenerateColumns="false">
        <MasterTableView DataKeyNames="ID">
        <Columns>
        <telerik:GridTemplateColumn UniqueName="Name" HeaderText="Name">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("Name") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="Description" HeaderText="Description">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("Description") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="StatusName" HeaderText="StatusName">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("StatusName") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="ParentRoleId" HeaderText="ParentRoleId">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("ParentRoleId") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
        </Columns>
        </MasterTableView>
        </telerik:RadGrid>

         <telerik:RadGrid ID="RoleFeature" runat="server" AutoGenerateColumns="false">
        <MasterTableView DataKeyNames="ID">
        <Columns>
        <telerik:GridTemplateColumn UniqueName="Name" HeaderText="Name">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("Name") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="Description" HeaderText="Description">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("Description") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="StatusName" HeaderText="StatusName">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("StatusName") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn UniqueName="ParentRoleFeatureId" HeaderText="ParentRoleFeatureId">
        <ItemTemplate>
            <asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("ParentRoleFeatureId") %>' />
        </ItemTemplate>
        </telerik:GridTemplateColumn>
        </Columns>
        </MasterTableView>
        </telerik:RadGrid>

My aspx.cs code is

protected void Page_Load(object sender, EventArgs e)
      {
          if (!Page.IsPostBack)
          {
              ApplicationProcess a = new ApplicationProcess();
              Roles.DataSource = a.GetRoles();
              Roles.DataBind();

              RoleFeature.DataSource = a.GetRoleFeatures(1);
              RoleFeature.DataBind();
          }

      }

Thanks in Advance..!
