ASP. NET Custom User Control-text box with drop-down box

You can enter the content or select a text box in the drop-down box.

However, ASP does not have such a control. Now it is switched to ASP. NET, and it is found that ASP. NET does not have such a control.

I had to use the old method in ASP to implement it through a text box + a layer.

However, it is inconvenient to use. Every time, you have to write a large and long script for calling. And it is difficult to reuse.

A simple user control is written when you are free.

Source code. Example:

PS: only functions are implemented, and the interface is not beautified. Because I don't know that.
