I have a ComboBox filled with a custom Class called TableHeader, this class contains two propertys, TableName and TableText, i have set the ToString() funktion to return TableText since its what i want to display but how do i get the TableName returned?
View 1 RepliesMy question is, the SelectedItem property of the Combobox is supposed to return a integer value, is it not? Because I am getting back integers, sometimes, then the next time through I get back a String. Has anyone else had a problem like this with the Combobox?
View 4 RepliesHow to override the SelectedItem property? When you look at the description of the SelectedItem property, the description shows as:"Gets the selected item with the lowest index in the list control". I would like to bypass the "lowest index" portion of the property...I have multiple items in the same list with the same value, but different text. I just want to set the SelectedItem to the actual item I've selected, not one with the same value that appears earlier in the list...
View 16 RepliesI'untangle a particularly malodorous collection of spaghetti code. Anyway, I have the following XAML code:
<UserControl.Resources>
<CollectionViewSource x:Key="XMLObjectGroups" Source="{Binding Path=XMLObjectList}">
<CollectionViewSource.GroupDescriptions>
<PropertyGroupDescription PropertyName="IsDateType"/>
[code].....
On the second line XMLObjectList is a readonly property of a ViewModel class, returning a Collections.ObjectModel.ReadOnlyObservableCollection(Of MyOrder).On the final line SelectedOrder is a property of the same ViewModel class, which allows setting and getting of a MyOrder object.
I have confirmed that XMLObjectList is being correctly referenced by renaming the property, mistyping the string, breakpoints, etc. XMLObjectList definitely references the XMLObjectList property of this particular ViewModel class.The SelectedOrder property, however, is never accessed at runtime, meaning that it isn't properly hooked up to the SelectedItem of this ListView.
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?

Once the user enters their first and last time for the first time it'll be stored in the combobox's index..Now my issue is this...

View 3 RepliesI've got a ComboBox with an ItemsSource which I've bound to a List(Of String).What I'd like to do is have the XAML update a String property when the SelectedValue of the ComboBox changes. I've seen a whole bunch of examples for TextBoxes which use

I have a form created in VB.net. It is used to get some information form a user. The form is not bound to any data source.A combobox on this form is used to enter a cost. I want the value entered by the user to be displayed using currency format.

This put C2 into the FormatString property.When I run my application, this format is not applied to the value entered into the combobox at the time the number is entered or when I leave the combobox.

I have been searching for an easier way to validate the text property of my combobox.
Below is a background of what I am try to accomplish:
I have a from that contains many controls, mainly comboboxes that are bound to datatables. I have these set up in such a fashion as to when the user begins to type, the values begin to show and auto populate the combobox. This makes the selection process easier to select an actual value in the list. But, as we all know, you can lead a horse to water but you can't make him drink. Users still have the ability to type something that is not in the list. I do not want to allow them to leave the combobox until the have selected or typed a valid value from the list because I am building a SQL query to retrieve data for a later form. I don't want to lose the above mentioned functionality of being able to type it in. I currently have it working as follows, but there must be a more elegant way to do this.
I first populate my combo box like so:
CODE:
The part I don't like the most is that I feel like I should be able to use the list already loaded in the combobox data, but I can't figure out how to do it. So I end up having to reload it, this seem like a waste of time.
Im currently debugging my application to found out why it's running a bit slow, when I put breakpoint where i populate one of the application combobox it's run fast but after i populate it and when I'm trying to set the its selectedindex to zero the program halt for about 2 second.. this is the line where the program get stuck for 2 seconds:

I'm rewriting a VB6 application in VB.Net. So far I have 2 forms, frmLocations (frm1) and frmLocationInfo (frm2). frmLocations has a combobox, cboLocations, from which a selection is made and an "Ok" button is clicked, which then loads frmLocationInfo. frmLocationInfo has a series of textboxes to display info corresponding to the location that was selected - Location, Location Number, Phone, Fax, Email. There are also 3 comboboxes on frmLocationInfo - cboDepot, cboFreight, and cboDispatcher. I need their text property along with items to be populated, also with data corresponding to the initial selection made on frmLocations. I'll spare you all the difficulties I'm having w/the other comboboxes, and instead focus on cboDepot. I have gotten it to populate its text property to display the corresponding Depot, however, the items are not populating and all you see now when you click on the dropdown arrow is only the depot that shows up in the text property.
Here is the code for this portion.
