management tooltip from vb code

[Fabio Cirillo]

Hi,
I have this tooltip:

<telerik:RadToolTip ID="RadToolTip1" runat="server" TargetControlID="Imgprofile"
    ManualClose="true" Width="140px" Position="MiddleRight"
        Skin="Simple" RelativeTo="Element">
    <telerik:RadButton ID="RadButton1" runat="server" Text="Carica foto"
        Width="130px" ButtonType="LinkButton" Skin="Office2010Silver">
        <Icon PrimaryIconCssClass="rbAdd" PrimaryIconLeft="4" PrimaryIconTop="4"></Icon>
    </telerik:RadButton>
    <hr />
    <telerik:RadButton ID="RadButton2" runat="server" Text="Rimuovi foto"
        Width="130px" ButtonType="LinkButton" Skin="Office2010Silver">
        <Icon PrimaryIconCssClass="rbRemove" PrimaryIconLeft="4" PrimaryIconTop="4"></Icon>
    </telerik:RadButton>
</telerik:RadToolTip>

that allows you to upload your profile picture, or remove it. I wish that when I open the webpage if the image is not in the database, this tooltip appears automanticamente and that the "remove image" is disabled. However, if the image is loaded then the tooltip should not show but if you go above the image with the mouse then the tooltip to appear and must be enabled buttons.

all this should be done by code vb net, code behind because I can manage to code if the image is loaded or not.

Just use the Enabled property of the buttons to toggle if they are enabled according to your flags/database/whatever.
Use the Show() server method to show the tooltip from the code-behind if you need to.
Set the desired target as a TargetControl and the tooltip will show when it is hovered.
