I would like to know more about how the ASPNET runtime assigns unique control IDs to the controls on a page. I'm curious because it doesn't appear to be "fixed"...which causes problems with composite controls which contain controls doing postbacks. Here's what happened to me: I have a textbox an...more >>

Hi, I created a very simple server control, but i cant bind it in web.config, i keep getting this error message: Parser Error Message: Could not load file or assembly 'LaberImage, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d757f12d29dc4c83' or one of its dependencies.

I have a custom composite control decorated with ParseChildren(false) and PersistChildren(true) because I want to parse the inner markup for custom controls. That part works fine.

I have a custom composite control whose markup needs to contain child controls, an array property, and simple properties, all as nested tag elements, e.g.: <cc1:MyComposite runat="server" id="whatever" SimpleProp1="somevalue"> <ChildControls> <-- this is a property collection, of controls <...more >>

I have a custom control in a Formview. This custom control consists of a textbox, a label and some code-behind. The code behind generates a codenumber in the label based on a database and the entry in the textbox. Everything works fine. I bind with two properties the textbox and the label text...more >>

When creating a property for a server control can you set some sort of "required attribute", so that the developer sees the browser message you see when you leave off an attribute on a Microsoft control: Parser Error Description: An error occurred during the parsing of a resource req...more >>

In design-mode, when my databound composite control creates its child controls and adds them to its control collection, the designers for the newly-created child controls (which are also composite databound controls) don't get called. Why is that? I thought the designer was always called when a ...more >>

Okay, I'm confused: I have a custom composite control which has several "steps". I've created the DesignerActionList infrastructure to move between the steps at design time. The methods that control the movement get called, the "step state" gets changed...but the design surface doesn't update to r...more >>

I have a GridView as a child control in a custom composite control which is stubornly refusing to databind at design time. I'm convinced I must be missing something about how the databinding process works differently at design time. Here is the code that constructs the GridView in CreateChildCon...more >>

I used to know how to hijack the last cell of a datagrid when it's selected but can't seem to with a gridview. It's been a while, but I seem to remember adding something like this "</td></tr><tr><td colspan=4>testinghere</td></tr>" to get another row that I could edit. I don't know what's best...more >>

I'm building a custom control which is essentially a customized version of the Wizard control, although it doesn't derive from the Wizard class. It's designed so that you can add a sequence of a limited number of types of steps to the control (e.g., an Introduction step, a grid-select step). Th...more >>

I've written a "SmartWizard" class that essentially adds initialization and exit handlers for the individual steps, allowing for easier control over how a user walks through the wizard. But I've run into a problem with the design-time support. With a regular Wizard, clicking on a step in the sid...more >>

I'm in a bit of a pickle here: I've got some kind of problem involving persisting some complex properties on a custom control, but because VS2005 SP1 keeps crashing when it encounters the problem I'm at a loss as to how to figure out what's wrong. Here's a sketch of the custom control and proper...more >>

Hi, I have a datagridview column that will contain both editable and non-editable values. I have set the columns readonly property to true. I then use the AddRows event to check the value of an hidden column and if that is false i set a specific cells readonly property in the column to fa...more >>

I wrote a customized derivation of the Wizard control, which works fine at runtime, but doesn't behave properly at design-time. Specifically, when I click on the links for the individual steps at design time, the display doesn't update to let me see (and edit) the controls contained in that partic...more >>

Hello and TIA. I have a very simple server control that has one property that needs to be rendered in an ITemplate.
