how to have both server controls and html controls rendered in a custom control?
I have a custom control in which there is an html text box.when you click on it , a div containing a table is appeared and according to what you select in that table a text is set to the text box.

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...

Handling events from controls within custom controls
Hi, I have created a custom control that behaves similar to a placeholder control. In the Render control I simply render the sub-controls that have been programiatically added, like this: protected override void Render(HtmlTextWriter writer){    foreach (Control control in Controls)    {        control.RenderControl(writer);    } ... This is fine. I can programatically add a button with an event handler to this control in the code behind for my ASPX page, and it works with no problem. However, if I add a...

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. Be sure to implement INamingContainer to that inherited Control too, thats the important point of that approach.--Microsoft MVP - Visual Developer ASP / ASP.NET- http://www.aspnetzone.de/blogs/peterbuch...

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...

Unable to use Custom Control within a datagrid control
I have a datagrid and a template field to look like this <asp:TemplateField> <ItemTemplate> <customControl:Display runat="server" Description='<%#DataBinder.Eval(Container.DataItem,"Description")%>' /> <asp:Label ID="mylabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"ReportID")%>' /> </ItemTemplate> </asp:TemplateField> My custom control has a property called "Description" which basically is nothing but the value for a label in that control. Now, in the above code, the asp label control correctly displays the text,...

Events and dynamically created controls (within a custom control)
I've created a custom control that displays a list of folders from a directory.  The user can click a folder (ImageButton) to drill-down and view the files within the folder.  I've developed the control by adding rows and cells to a <asp:Table>.  I create the controls within the cells (ImageButton and Labels) dynamically based on whether we want to see the folders or the files. Originally I was drawing the table depending on whether Folders or Files were desired but I realized that this will not work because on postback the target controls don't always exist...
