View 1 RepliesI need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.

I can add items to a listview this way:[code]But how can I set the Tag property of that same item as the same loop? I tried going ListViewItem.Items (0).Tag = "something"..But that doesn't seem to do the trick. How do I do this?
View 1 RepliesThis problem refers to VB 2008. My ListView Property is named lvSummary, View is set to Details, 2 columns are defined, and this is the code is being called when I click on the menu Summary item:
Private Sub mnuSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSummary.Click
Summary.ShowDialog()
Summary.lvSummary.Items.Clear()
[code]....
The problem is that when I click on the Summary menu item the first time, the numbers "1" and "2" do not appear in the listview columns. I then close the window by clicking on the OK button, then immediately click on the Summary menu item again, and this time the numbers DO appear! What am I doing wrong to cause these numbers to not appear the first time?
I have a list view with Two Columns. I want to set text in the Column Header as "Bold" & Text Align as "Center". But the text in the rows of the list view not required bold & center.
So, How to control them independently...?

How to modify the Height of the rows...?

I am trying to loop through through all of the items and subitems in a listview control and add them to an xml doc like so:

I'm trying to create a Window with a ListView and an Area where details to the selected Object are displayed. The Listview displays items stored in an ObservableCollection(Of T) Collection. The items itself contain also an ObservableCollecton(Of T) Collection which should then be displayed in the details area in another ListView, accordingly to the selected item of the first ListView.
The Problem: The InitializeComponent() throws an Exception (XAMLParseException).
Exception:Set property 'System.Windows.Controls.GridViewColumn.DisplayMemberBinding' threw an exception.
InnerException:Object of type 'System.String' cannot be converted to type 'System.Windows.Data.BindingBase'.
The Line- and ColumNumer of the Exception are Pointing at the <GridView> of my ListView (.View).This is the First ListView
<ListView ItemsSource="{Binding Path=MyObjectCollection, Mode=OneWay}" SelectedItem="{Binding Path=Selected, Mode=OneWayToSource}">
<ListView.View>[code]....
So. How can I bind to the Collection Property of an Object could be nothing?
I've recently taken over a MVVM project started by someone who's now left the company; It's my first time using WPF, but by the looks of it, it was his first time using both WPF and OOP...Anyway, I've got a ListView in the XAML, and I've got a collection class which doesn't currently contain a "SelectedItem" property.what code I need to put in to link the SelectedItem of the ListView to the as-yet-unwritten SelectedItem property of my collection, and then what code I need to put in so that the SelectedItem of the collection links back to the ListView?
View 2 RepliesI've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.
But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.
This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)
'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)
[Code]...
But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)
Well, the question says it all. I have tried the _.SelectedItems(0) method, but it is not working at all. It only works for the first item, but for all others it says that "0" is not a permissible index value, or something like that.NOTE: All of my items are constant, as in they will not change. None will be added, and none will be removed.
View 4 RepliesI inherit from ListView. I want my control to have an AllowCheckBoxes property rather than a CheckBoxes property.
Listview.Checkboxes is not overridable.
Can I add attributes to Listview.Checkboxes? Maybe the following?
<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
If not, does the following make sense?
<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
Public Property Shadows CheckBoxes() As Boolean

What about using
EditorBrowsableState.Never)

View 1 RepliesI already have one year experienced in c++, and built many private applications.My question is simple to ask, and simple to answer I think.When I select an item in a listview, I want the full item to be selected. Now only the TEXT in the listview item is selected. I've made a picture to clearify my problem.The picture in the link below is splitted up in two pictures. It shows what I currently have, and what I want (my aim)

View 1 RepliesI have a database that is connected with my form. There is a combobox on top of the form and with that I can select the category I want.
Now when I search or I do something else it selects records that aren't from the category I selected, so this category should change when I do such things. Nothing happens when I do something. It should select the right category that belong to the record that is selected now.

View 3 RepliesCombobox with bound rowsource, but I want to change the displaymember to a string returned by a procedure. In Access/VBA I would have a little function to build the string, then simply code the recordsource of the cbo as:

Pretty straightforward, but I've messed around with this for hours in VS2005/VB to no avail.SELECT ClientIDS, fnGetName
My question: i have a combobox which i would like to populate with data from a database. The table looks like this: pkIntCompany (the pk) & chrCompanyName You see nothing special.
