Refrencing Auto-generated Controls?

Jan 10, 2011

I have a VB 2008 app that creates controls at runtime. I can read these controls EG: textbox or dropdown by the following line.

<code>
TXT_value = CType(Main.Controls.Find(TXT_item, True)(0), TextBox).Text()
</code>

I can see the value but sometimes.. Sometimes I get a indexoutof range exception.

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...

that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

C# - Force Resharper To Use The CLR Type Names For Auto-generated Code?

Nov 4, 2011

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.

Code-generated Controls And Memory Usage

May 29, 2011

I have started with a small project in VB2008 Express which grew to a complex application. I have deployed the application recently discovering it is rather small, and the major issue is that code-generated controls (checkboxes, comboboxes, textboxes) are not displayed as during development. I have declared the code-generated controls in the declaration region, and there are about 250 controls. According to user selection some of the controls are added to a container panel. Now, I am concern that because I declare those as public (static?) variables, it uses much memory and causes the problem in the compiled application. Is that correct that static declared and code-generated controls uses much memory? How to avoid it ? I need the controls as public variables. Is it better to add all 250 controls on the form in designer mode, and use the property Visible (control.visible=True)?

The Code Automatically Generated By VB Forms When Adding Controls

Mar 27, 2012

In the early generations of VB.NET visual studio, I used to see an automatically generated region named "Windows Form Designer generated code" that includes the code that generates the controls at the surface of a form. But what happened with VS 2008, I can't see that region any more ? Where are the lines of code that are automatically generated that create controls and set there properties ?????

IDE :: InitializeComponent Generated By Designer Puts Controls In The Wrong Order

The code generator creates code with references to a component I am using, before it's dependent components (datasets) are initalized. Although I can correct this by editing the form.designer.vb file, everytime I make a change on the form the code is re-generated in the wrong order. Where does VS2008 store information about the order of the components for code generation.

This Runs:

Unable To Save Values Into SQL Server From Dynamically Generated ASP.NET Controls

Jul 13, 2011

I have an asp.net web forms application. In this application, students upload assignments and submit a survey along with it. For the survey, I read values from DB and dynamically generate ASP.NET Controls like radiobuttonlist, checkboxlist, textbox on the form during gridview's RowDataBound Event. I cannot do it in Page_Init method because I create only if a user click on a specific assignment which requires a survey to be submitted.

When I submit the survey form, the survey values are not saved into database. During debugging I figured it out that the values are not available in the codebehind page. The radiobuttonlist.selectedvalue returns and I get following error[code]....

Auto-Aligning Controls On Form?

Feb 11, 2010

I converted a VB6 application to VB.Net and in doing so, I seem to have lost the ability to auto-align the controls on the form. I thought I could change that in the "Tools > Options > Windows Forms Designer > General" area but that doesn't seem to work. Anyone have any ideas? I really don't need to use a grid for aligning since the auto-align functionality can be used but I just don't know how to get it back.
