When changing selecteditems (the items themselves, not which ones are selected) in a multiselect listbox, sometimes the operation does not happen and items are deselected. Here is a simple example of what I mean, just a form with a multiselect listbox.
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("item at index 0")
[code].....
i want to remove all selecteditems i tried to use this loop but it didn't work
Dim a As String
For Each a In History_Textbox.SelectedItems
History_Textbox.Items.Remove(a)
Next
How do i do it because that just didn't do anything
I have a Master List in the DataGrid that displays all the "Monitors" - think of them as Audits (for context). Basically when a user clicks on a row in the DataGrid the TextBoxes, ComboBoxes, CheckBoxes and DatePickers all show the values and the user can edit them there and that all reflects in the DataGrid just fine.How do i go about using the same TextBoxes, ComboBoxes, CheckBoxes and DatePickers to add a new record?

Without using MVVMLight, I need to implement drag and drop for photos onto a listbox using mvvm using Icommands preferably and interaction triggers, however if i use commands then I don't know what to pass in for a command parameter? Any ideas? Thanks.

Public Property DropCommand As ICommand = New Adjuster.DelegateCommand(AddressOf dropImage)

2nd question. How can i bind other queries from different table to these columns. like Column[2]and Column[3] should come from a different query.
While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

This is an experiment to learn something.
I have a class called logitem
it has a datetime property, and a message as string property
I have declared myLogEntries as List(of logItem)
I have a ListBox.
Ok now what?
I have searched but i am getting lost in all the examples.
I have set the ItemsSource=myLogEntries
I think i need a datatemplate or maybe to specify binding source.
I am doing all this in the wpf form loaded event.

View 4 RepliesI need to display the selecteditems in a label I am using VB 2005 I set the selection mode to multi-extended It did work selecting only one item with the following code:
me.xresultslabel.text= me.xlisttextbox.text.selectedItem.tostring
But when I tried to display more than one item using the following code:
me.resultlabel.text= me.xlisttextbox.text.selectedItems,
I get the following string on the label:
system.windows.forms.listbox+selectedobjetcollections.
int val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.
I was testing to get the values from the ListView which works fine when double-clicking a row in the MouseDoubleClick_event, but in the SelectedIndexChange_event it crashes. I get an error that the value of "0" is not valid for the index.
