Hello all, I'm trying to build a user control (specifically, a date picker) and am experiencing several issues. Also, I'm brand new to web development and ASP.Net, so hopefully this will be fairly basic. First, when I place the control on a WebForm, the designer lets me place it exactly where I want it. However, when I run the app, the control is displayed in the top left corner of the parent container regardless of where it was in the designer. Second, when the control is loaded, I run a method to fill the month, day, and year DropDownLists with their values. However, they are empty when they are displayed. I know the code is executed, because I can throw an exception in the method. The AutoPostBack is set to true but I don't think this is ever triggered. One way I can think of is to force a PostBack but it doesn't seem that I'd need to. Thirdly, if I have the control in a separate .dll that is referenced by the web app, and include the namespace that it is under, I get the following exception when attempting to run the app, even though I've only got it defined in one .dll that is referenced: "CS1595: 'CustomWebControls.DateTimePicker' is defined in multiple places; using definition from...". This is a problem because I want to be able to access the object in C# code. Lastly, how do you add a user control to the toolbox? When I select customize toolbox, and find the .dll that the control is in, I'm told that there are no items in the .dll that can be added to the toolbox. Thanks in advance, Shannon |
