Hi,

Please try the following code snippet to achieve your scenario.

ASPX:

<telerik:RadWindow ID="RadWindow1" runat="server" VisibleOnPageLoad="true">
    <ContentTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server">
            <Items>
                <telerik:RadComboBoxItem Text="Item1" />
                <telerik:RadComboBoxItem Text="Item2" />
            </Items>
        </telerik:RadComboBox>
        <telerik:RadComboBox ID="RadComboBox2" runat="server" EmptyMessage="select" ValidationGroup="Group1">
            <Items>
                <telerik:RadComboBoxItem Text="Item3" />
                <telerik:RadComboBoxItem Text="Item4" />
            </Items>
        </telerik:RadComboBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ValidationGroup="Group2" ControlToValidate="RadComboBox2" ErrorMessage="required">
        </asp:RequiredFieldValidator>
        <telerik:RadComboBox ID="RadComboBox3" runat="server" EmptyMessage="select" ValidationGroup="Group2">
            <Items>
                <telerik:RadComboBoxItem Text="Item5" />
                <telerik:RadComboBoxItem Text="Item6" />
            </Items>
        </telerik:RadComboBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ValidationGroup="Group1" ControlToValidate="RadComboBox3" ErrorMessage="required">
        </asp:RequiredFieldValidator>
        <telerik:RadButton ID="RadButton1" runat="server" CausesValidation="true" Text="Validate" OnClick="RadButton1_Click1">
        </telerik:RadButton>
    </ContentTemplate>
</telerik:RadWindow>

C#:

protected void RadButton1_Click1(object sender, EventArgs e)
{
    if (RadComboBox3.Text == "" && RadComboBox2.Text=="")
    {
        RequiredFieldValidator1.IsValid = true;
        RequiredFieldValidator2.IsValid = true;
    }
    else if (RadComboBox2.Text == "")
    {
        RequiredFieldValidator1.IsValid = false;
    }
    else if(RadComboBox3.Text=="")
    {
        RequiredFieldValidator2.IsValid = false;
    }
}

Thanks,
Shinu.
