I have created a user control and need to know how I can let the user change some of the properties of this control at runtime and have the values persist on next startup. There are multiple instances of this control on the form.
View 10 Repliesi've written an app to enumerate forms + controls in a project at runtime:
it lists form names in a listbox + when a control is selected, it lists hierarchical controls in a treeview. by selecting a control in the treeview you can view its properties in a propertygrid.
here's the problem: how can i use the propertygrid to actually persistently change those properties?
at the moment you can change properties in the propertygrid but it doesn't change the control's properties, either persistently or otherwise.
here's the code. (you can download the full project at: [URL]
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.AddRange((From t As Type In Me.GetType().Assembly.GetTypes() _
Where t.BaseType Is GetType(Form) _

I have created a user control with some properties but when I change them in a form and build the return to the default value, Here is the code I did:
Public Property ButtonFind As Boolean
Get
Return CmdFind.Visible
End Get
Set(ByVal value As Boolean)
CmdFind.Visible = value
End Set
End Property
For example here i have create a user control. the user control contains labels. when the user hit right arrow button on keyboard, the control will appear on form1. when the user control is there. user can select a label. and when user hit buttons on keyboard, the label.text will change according to the button hit on the keyboard. i have done this code. i just write it roughly here.

is this code above should i write on usercontrol1 code area or form1 code area? because i got confused here.
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.
View 4 RepliesI'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.)

View 4 RepliesHow 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.

In a user control I have the code shown below.

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.
View 1 RepliesI've created a user control that is basically a Panel that contains 1 label,3 TextBoxes and a few properties that set/get some short integer values.During a form load event I display a number of these Panels.I then access the Panels name (and other panel properties) via a user-created handler for the panel's click eventHowever I would really like to access the values from the user-control's properties.

What I want to do is to make my application to SendMessage to another application. I can send message perfectly when i set keys.F1 or F2 etc in code but, I wonder, is it possible that user change this key in runtime? I was thinking about doing something like:
If combobox1.text = "F1" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F1,0)
elseif combobox1.text = "F2" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F2,0)
etc...
But I have 19 usable keys and alot of events with SendMessage function so code will be so big and there's possibility for slowing application. Is there anything that I can do, like...
Dim hKey as STRING? INTEGER? WHATEVER...
SendMessage(pHwid,WM_KEYDOWN, Keys.hKey,0)
?

View 4 RepliesI'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.

In my asp.net 4.0 application I have a standard set of tabs controls across the application that has one tab for Search, one for View and one for Reporting.I am in the process of updating those tabs and I was hoping to be able to wrap their functionality up into a single user control since they all function in pretty much similar ways. The issue I am having is how to create a property called SeacrhTab/ViewTab/ReportTab that allows me to assign a different user control to it depending on the area of the application (e.g. CompanySearchControl, ContactSearchControl, etc.) Anyone ever tried to accomplish something similar?

View 8 RepliesI've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls
If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then
''Do some stuff
End If

After taking a few years off from programming, I decided to start learning vb.net. I have created a user control that contains a picture box. I added some custom properties to the picture box that will hold general string data from a database.
My problem is that the user control is programatically created during run time, and during this time a DoubleClick event handler is added for the picture box that is within the user control.
I need to be able to set the custom properties for the picture box during the creation of the user control, so that when the control (picture box) is double clicked I can read these values but am unsure on how to access them.
The picture box is the entire size of the user control, or I would just add the custom properties right to the user control and add the DoubleClick event handler to that. However, double clicking needs to be done on the picture box since it takes up the entire user control, unless anyone has an idea to trigger the DoubleClick event of the user control when the picture box is double clicked.
