I am using the winform datarepeater control from vb.net power pack. All of the items on the repeater are readonly except for a checkbox column.I want to iterate over the items and find out which checkboxes are checked. I can't find a collection of datarepeateritems on the control and help is scarce.

View 2 RepliesHave a populated listview with check boxes. If the item is checked I want to send it to report for printing. This code is bypassed:
Code:
Private Sub GetSelectedItems()
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Count is always = 0. This seems to work only if the item is double clicked. And then only one item is returned in the msgbox. MSDN says "The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property."
When I tried to check for the handle, an error said something about overloading. So I added this:
Code:
Public Overloads ReadOnly Property GetSelectdItems()
Get
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Which does not help. How to find the items checked/create the needed handle?
Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

I am trying to iterate through all the connection strings in App.Config using VB.net.
I would like to:
1. Get a count of all the connection strings
2. Put them all into a listbox.
I have tried using System.Configuration.ConfigurationSettings but am unsure exactly how to get the collection/listof connection strings.
The application is a WinForms VB.net .net 4.0 app.
I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
I have 3 asp.net standard checkbox control and 1 textbox. I check 1 and 3 checkboxes. In textbox how to calculate how many checkboxes are checked? If I checked 1 then textbox result is 1. If I check 1,2 the textbox result is 2. If I check all checkboxes then the result is 3

View 2 Repliesin my app I have to count the number of checkboxes have been checked to validate how many days were selected. 28 checkboxes in 2 groups of 14 to represent 2 pay periods. I tried counting the days by handling the CheckStateChanged or the CheckedChanged events of 14 checkboxes for each pay period, then if checked add 1 to payPeriod1 or 2. Either one of these works and counts the checked boes but when I try to reset my controls I get;

Example: That's 8 different combinations:
1, X, 1
1, X, X
1, 2, 1
1, 2, X
X, X, 1
X, X, X
X, X, 1
X, 2, X
Any way to get the different combinations depending on the Checked checkboxes into an ArrayList. One entry per possible combination (like the example above). Note this example is just for 3 games, I will have 13 games in my program so if you click all checkboxes thats 1,6M combinations. Is it really wise to have 1,6M entries in an Array? I also want to be able to set demands, like: delete all lines in the Array containing two X. Maybe an ArrayList isn't the way to go?
Alright I'm very sorry. This is a very Noobish question and I thought I could figure it out my self but I am haveing alot of trouble.Okay so I have 5 Checkboxes. When All them are checked I want Button1 to be enabled.And if any Checkboxes get unchecked after they where checked I want button1 to be disabled.
Now I think I got the code right. I just don't know what event to put it under. If checkbox1.checked = true and If checkbox2.checked = true and If checkbox3.checked = true and If checkbox4.checked = true and If checkbox5.checked = true then Button1.enabled end if

View 2 RepliesI wanted to see if I could have a list of six check boxes with names of a certain author that people have or have not read. When they are asked to check all that apply to them and then hit submit I want a label to display a message depending on the number of checks they made. So if they have 2 checks marked off then a message could say, "You do not read much of this authors books?" or 5 could say " You like this author, don't you?".

View 6 RepliesI know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.

How can this be done using ASP.NET webforms controls?
Suppose we got a form with some checkboxes. Each ckeckbox represents a method of the same class. Each method takes no arguments, returns no values. Is it possible using a delegate to loop through the checkboxes and run only the methods being checked?

I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?

I am working on a project. Part of my project requires me deal with datagridview in windows form. I used 'Choose Data Source' wizard to display data from Microsoft SQL Server 2005 and into the datagridview. In my windows form, I have a datagridview with the columns - Email , CustomerNam e and Select. I also have a Add Contact button.
I have 2 questions which is:-
1) How do I insert checkboxes in the Select column
2) Upon inserting checkboxes in the Select column how do I display the rows, that I have selected using checkboxes in the Select column, to display into the textbox in another windows form?

Dim Navigator As XPathNavigator = Xml_Document.CreateNavigator()
Dim ns As XmlNamespaceManager = New XmlNamespaceManager(Navigator.NameTable)[code].
