Add Properties To Every Control With A Specific Name/pattern In The ID - ASP.NET (VB)
Oct 27, 2011
I have several controls on a page that contain the word "DATE" in the ID. These are specific text boxes for dates only.
Here is an example of what I need to do for each text box control with "DATE" in the ID:
Birth_Date.Text = fnLib.formatDate(Birth_Date.Text, 1)
Anniversary_Date.Text = fnLib.formatDate(Anniversary_Date.Text, 1)
Rather than do this for every single control, is there a way I could do this in some kind of For Each Loop?

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

I have my own class of graphic objects, and now I'd like to allow a user to right-click on one of those within the application and see a properties window. Is there a pre-built dialog or control for displaying properties at runtime? I'd like to have something just like the IDE properties window button for my application.

I am using Fluent NHibernate to map out an existing database. For this reason - automapping isn't an option for me.How do I tell NHibernate not to map certain properties? Many of them are read-only, and the others do not need to be persisted for other reasons.
I am writing this in VB.Net.I get the typical error message:"The following types may not be used as proxies should be 'public/protected virtual' or 'protected internal virtual'"I have purposely not made my objects Overridable (equivalent to virtual in C#) because I do not want NHibernate to touch them.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.

I tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.

i had designed a form with various controls added some days ago. Accordingly i had coded the controls. And today i didnt like the look and feel of the form, so i copied the controls for a while and then re-pasted it over a new control (panel). Now when i double click to see the underlying code of the control generates a new event. I mean i had a button as Button1 and its underlying code was under the Button1_Click event. But now its is like Button1_Click_1 which i dont understand. Is it due to formation of control array or what? I want the button to be remapped to Button1_Click event.

I am able to bind my datasource to the textblock for the display text. However I would like to set the Fontweight to bold if the value of the checkbox foo is checked. I'm trying to use IMultiValueConverter to accomplish this, but have had no luck so far.
<CheckBox Name="foo"/>
<TextBlock Name="bar" Text="{Binding Path=Name}">
<TextBlock.FontWeight>

In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl
Public Enum EnumVisibility
Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.

I have a blank winform. A textbox control with name textbox1 being added to the winform. During the form load event, I retrieve 2 string values from database and store these values into TextboxName and TextboxValue variables of string type.
I use TextboxName variable to store that textbox control name (i.e. currently TextboxName = "textbox1") and TextboxValue variable to store that textbox's text (i.e. currently TextboxValue = "Hello world"). My question is how to set the textbox1.text property without have to resort to following code:
If TextboxName = "textbox1" Then
textbox1.Text = TextboxValue
End If
how to set the textbox1.Text property without have to use IF...Then construct?

adding the properties of a control to its parent? Without having to rewrite all the properties... For example, if I have an user control with a button inside, and I want to have the "text align" property of the button, in the list of properties of the usercontrol. If not, is there a way of making the child control of an usercontrol editable?

I've built a custom user control in VS2010, incorporating two datagridviews, and asplitpanel - The idea is that there is a "Main" datagridview control, and the second is an internally controlled grid that (when shown) displays the Columns which are set as invisible. This allows the user to drag the columns onto the main grid, in order to display the columns.This all works fairly well. I've set the modifiers property on the Main DataGridView to public, so that by and large, the developers can make use of the control just like a normal DGV (albeit with an extra level to the code).
I've also created dummy events for each of the events that the DGV normally raises, and pass them through the usercontrol, so that the developers can attach to the DGV events as normal. Again, this appears to work fine.Unfortunately, I've run into a problem. I'm trying to set the RowSizeMode to DisplayedCells (or indeed any value). If I try it in the designer, it appears to retain the change until I run the application, after which the property reverts back to normal.

I'm wanting to dynamically create some controls relative to controls already placed on the forum at design stage, how do I find the locations of the controls that are already placed?For example, I have a label called lblDateTime, its location is (13, 167) and its size is (65, 13).In my code, I want to place a new label below this label.I've tried to set the location and size properties of the new label using the location and size properties of lblDateTime.Size works, no problem, but the location of lblDateTime always returns as 0,0.[code]I want to set lblMessage DateTime. Location to (13, 180), but I'm actually setting it to (0, 13)What confuses me most is that Me.lblDateTime.Size is returning the correct values, so it's not like my code isn't finding the control.

I've been dealing with this kind of problem in many cases now, I try to edit the properties of a button or a label or smth else from a backgroundworker or a timer and I would get the "Cross-thread operation not valid: Control 'Label' accessed from a thread other than the thread it was created on." Now what I am dealing with in the backgroundworker is 3 things: reading/writing to labels' names, editing the checked state of some checkboxes and changing the enabled property of some buttons/pictureboxes. Check the screenshot for more info.

Greetings. I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.
Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.
I tried a repair re-installation. The same things happens.
I can set properties etc. programatically, but that sorta defeats the point of an IDE, not so?

Using Visual Basic 2008 when (in the past) I looked at the properties window for a control, the very bottom of the list of properties has a brief explanation of the specific property selected.
This has disappeared and I can not find any way to get it back. I tried the Tools/Options menu with no success.

How can I read the properties for a given contol type at runtime without having the masive overhead of specifing the each property for each type of control in code.
For example supose you are building an application where the end-user selects a contol type form a drop-down list in a combobox then the properties (Read, Write, Runtime, Designtime) for that control are displayed in a listbox.
