One of the questions that comes up every now and then on the "Atlas" Control Toolkit support forums is how to point both the PopupControl and the TextBoxWatermark at the same TextBox. The straightforward implementation doesn't work quite right because both controls assume they have complete control over the TextBox. What happens is that the PopupControl's result gets written directly into the TextBox where it partially overwrites the watermark that's already there. But the TextBoxWatermark doesn't realize anything has happened and assumes the TextBox is still empty. Nuts...
The solution to this problem is not immediately obvious, so I thought I'd post a simple example to help show how it's done using the 60731 release of the Toolkit.
First, here's what the sample code below looks like when it's running:
The complete code for the sample follows - most of what's there is just to get the necessary elements on the page hooked up properly. There are a few things worth noting, though:
That's all there is to it!
Just save the following code to an .ASPX file in the SampleWebSite directory of a Toolkit installation if you want to try it out for yourself:
