I am fairly new to Telerik controls and was experimenting with radtooltip and radtooltipmanager.


I created a tooltipmanager and a radtooltip from code behind with ID = "Test", rendermode = lightweight, title = "properties" and text = "CheckText". And this worked.

But when I went to add a radlabel I created as a control to it, saying


it wouldn't display it.

Can someone help me figure how to add controls to radtooltip or radtooltipmanager?

(Eventually, I want to add more controls like a table in the tooltip)


Thanks in advanced,

Swanand Nalawade

Hi Swanand,

The Tooltip can have either Text, or controls in its content. When the Text is set it is considered with a higher priority thank the controls, this is why the added Label is not visible. Removing the added Text should resolve the problem.

For example, you can have a similar setup:

    protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            RadToolTip RTP = new RadToolTip();
            RTP.ID = "Test";
            RTP.RenderMode = RenderMode.Lightweight;
            RTP.Width = Unit.Pixel(150);
            RTP.Title = "Properties";
            //RTP.Text = "CheckText";
            RTP.TargetControlID = "Image1";
            RTP.IsClientID = false;
            RTP.ShowEvent = ToolTipShowEvent.OnMouseOver;
            RadLabel lbl = new RadLabel();
            lbl.Text = "Some content coming from a label";
