Containers - Why All Contained Controls Within A Groupbox Do NOT Respond To Enabling / Disabling
Feb 10, 2011I'm working on a winform which contains several controls like textboxes, radio buttons, datagridviews... All of these controls have been added to a main group box called gbDataEntry. My problem is when the user is seeing the form, I set gbDataEntry.Enabled = False but I want to enable some controls like DataGridviews so the user can scroll them. After disabling gbDataGridview I set DataGridView1.Enabled = True but it seems that the datagridview does not respond to this line. Why?
View 1 RepliesRestore Settings From Another App - Label / GroupBox And CheckBoxes
Feb 16, 2012I am making an application that is designed to restore the settings for another application of mine. It so far contains 1 Label, 1 GroupBox and 4 CheckBoxes. The code I am making is designed so that when CheckBox1 is checked, CheckBox3 is enabled, and vice versa.
That does work, with this code in CheckBox1_CheckedChanged:
If CheckBox1.Checked = True Then
CheckBox3.Enabled = True
Else
CheckBox3.Enabled = False
End If
As I said, this code works exactly as intended. However, when I try to do the same with CheckBox2 and CheckBox4, using the following code in CheckBox2_CheckedChanged:
If CheckBox2.Enabled = True Then
CheckBox4.Enabled = True
Else
CheckBox4.Enabled = False
End If
It is the same code, basically, the problem is though, when I check CheckBox2, then CheckBox4 will enable, but when I remove the check from CheckBox2, CheckBox4 will remain enabled. [URL]

Dynamically Add Checkboxes In A Foreach Loop?
May 8, 2009I have the following for each loop which loops through a registry key and reads all the values:
Dim returnValue As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWAREMicrosoftWindowsCurrentVersionRun")
Dim keyname As String = "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun"
Dim values() As String = returnValue.GetValueNames
[code].....
What I am trying to have been highlighted in bold.. Each time the loop executes and reads a value from the registry, I want the code to create a checkbox which has a unique name and text according to the value that was read... So the number of checkboxes will depend on number of values that is got from the registry...But this doesn't work. It only creates one text box and the text of the textbox is also incomplete...

Feb 18, 2011I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked.
View 3 RepliesDynamically Output Checkboxes To Aspx Page In Program?
Feb 10, 2010I have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.[code]...
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET?

Dynamically Creating Methods For Dynamically Created Buttons?
Mar 15, 2011I have this code.
Code:
Public Class Form1

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

Getting The Order To Contained Controls?
May 10, 2010Suppose that one has a panel an inside it there are many buttons with Dock=Top. The button would tend to be stacked on top of the panel. How can I get a reference for each button from top to bottom? The button would be created in a random order, so I don't think that using the index of each button in the Controls collection of the Panel would suffix.

Can't Access Contained Controls At Runtime
Oct 16, 2009I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. This seems to work great! The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch.

Get The Type Of The Object Contained In An List?
Aug 11, 2010dim l as List(of MyClass) = new List(of MyClass) and I want to get the type of the objects contained in the list, how do I do that? The obvious answer, that doesn't seem to be possible from my actual implementation, would be to do something like this...

dim lResult as system.type = nothing
if AList.Count > 0 then lResult = AList(0).GetType
return lResult
end function
But what if the list is empty and I still want to know the type it contains?
