I'm displaying a listbox on the left with all available items, and a listbox on the right with currently selected items. Two arrow icons allow you to move...

This seems like it should be a simple thing to do, but I can't figure it out. I have a localized resource that I'm using in two places - one as a col. header in a datagrid, and then as a descriptor beside a field when the user edits a row. The text of the label looks like: Text="<%$Resources:Global,keyName%>" However, I'd like to ad...
I feel like this is something that Google should be able to solve for me just fine, but I'm finding little to no examples that I really understand. I have this custom control called UserControlTask. I wish to add an OnHide event to it and as the name implies, I want it to be thrown when the user control is being hidden. I seem to ...

I'm writing a custom control in ASP.Net 3.5 WebForms, using ASP.Net AJAX. I'm building a state toggle into the control (expanded and collapsed modes).
