How do I control one control from another control?
I have a page page1.aspx which is within a master page. On page I have a table with two cells. Within each cell I have placed two controls (ascx) that I have developed. Now I'd like to be able to get these two controls to interact. One needs to update the other. One has some search criteria that the other one needs to update its gridview. One needs to make the other visible/not visible at certain times. Out of the box neither control can see each other at all. Is there a good article or someplace I can find some information on how to do this?  AllAboutFocus.com. Information Technolo...

Custom Control within a Control Control

Add .Net Control to Web Custom Control
 I want to add .NET Control (like: TextBox, Button...) to Web Custom Control.How i can do it? Alphavn That's called a composite control -- "Mark As Answer" if my reply helped you -- Hello Guys What gunteman said, that is one approach and in most cases the right one.But its also possible to add child controls to a Control thats inherit from WebControl itself.

Architecture: .Net Controls vs. Custom Controls
I'm interested in managing users. i.e. Logins and profiles, etc.My question is, should I be using things like the Login control or should I program these from scratch? I dont like the fact that .NET creates so many things for me. This level of abstraction terrifies me and it feels like I have no control over the code .I've done a few huge sites in Classic ASP (million-hits-per-day type sites) and I'm not sure how robust certain controls are, or when to use them.Is, for example, the Login control aimed at newbies to .NET? Should it be used for the larger projects with thousands of...

DW control in VB. NET custom control
Hi Just attempting to investigate some DW.NET aspects. In regards to building a ancestor object with VB.NET, why is when I create a datawindowcontrol custom control that any reference to it is like (assuming that u_dw is the name of the DW control): custom_control.u_dw.DatawindowObject = "myDW" instead of simply: u_dw.DatawindowObject = "myDW" If I create a .NET custom control with a button on it, I can directly reference the button's methods and properties without having to qualify it with the custom control's name. When I was developing with po...

How do you control the placement of controls in a user define control
I have a user define control.  I put the control on the (C# Visual Studio 2008) page where I want them. When I run the program, the controls are all over the page.  How do I place them where they do not move form where I put them? You'll need to study the HTML output and see what it's producing, then start to look at how to do an HTML layout. hi, there are absolute and Relative position in html. I guess you must use relative position. For example, at design-time, you place a TextBox below an Image, at run-time, no matter what size is the image, the TextBox is alway bel...
