To add the extender in your Toolbox, follow the subsequent
steps.
Right click on the toolbox window then choose "Add Tab."
Type the name you want for the new tab then right click over
it, and click "Choose Items."
Click on Browse button in the ".NET Framework
Components" tab, go to the tool tip extender project, open the bin folder,
and choose MyExtenderToolTip.dll.
The result is shown Figure 3.

That is it, all you need now is to drag the extender, and
target the web control over which you want to display the custom tool tip.
As you see in Figure 4 and Figure 5, I dragged two tool tip
extenders, one for the textbox and the other for the button. Moreover, I
customized the Tooltip to match my requirements.

Figure 6 shows you how the extender properties are added as
new collection properties in the Textbox control.
