Listview selecteditem binding to textbox causing problems

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :WPF



I have listview and i have binded the listview selected item to a grid's datacontext. The grid contains a text box whose text property is bound to one of the columns in the listview. I have Add, Edit and Delete buttons to manipulate data in the listview.


Whenever i change the selected item in the listview the text in the textbox is changing. Since by default the binding is two way if i edit the data in the textbox it is reflectedi in the listview. But upon clicking on the cancel button the textbox value is not reverted back to old value. The list view itemsource is bound to an object of the class BindingListCollectionView

Code in button click event where BindingDetails is object of calss BindingListCollectionView. But this code does not rollback the changes in the textbox.


btnCancel_Click(object sender, EventArgs E)
  if(IsEdit == true)


I tried the following things.

How to disable textbox causing validation?

Hello I was running into a strange problem: If I left a textbox blank (in some instances) the textbox would not give up the focus (I could not even close the form).  I learnt later that this was because the text in the textbox was causing validation to fail.  I would have to type in some value (Satisfy validation) before i could close the form. This is problematic for me and I don't want the textbox to behave this way (I do not awnt front end validation).  I desire to have validation done ONLY on the back end.     I thought that I could solve this problem by changing the 'CausesValidation' property in the textbox to false.  This worked!  However it introduced a new problem.  The binding no longer worked on the Textbox.  That is, whatever value I typed in the textbox would not make it to the data set. What is the correct way in solving this problem???  I want validation to be shut off however I still (obviously) need to keep binding in tact...      

Owner-drawn ListView and nonstandard subitem size: selection problems.

Hello, I have a ListView whose first column is owner-drawn and items can be selected (I had to jump through hoops to draw the focus rectangle correctly). The problem is, my custom drawing displays the text in a wider font than normal, and only for this column. And when I click an item to select it, the right part of the text does not react, because the listview doesn't "know" there is text there (since it "thinks" the text is smaller). How can I correct this? Is there a "hit test" or "measure item" event or something, to tell the list view to consider a wider zone for clicks?

TextBox shows binding source text when window load, so why not with the ComboBox?

How can I get a ComboBox to show the binding source value when my window opens?  I have been searching all day for a solution to this, but cannot find anything.  So I have created a sample project to demonstrate my problem.  Below is a Vehicle class, very simple, two members Category and Make.  Category is an enumeration, Make is a string. namespace ComboExample { public class Vehicle { // Constants and enumerations public enum eCategory { Road, Air, Sea } // Attributes public eCategory Category { get; set; } public String Make { get; set; } // Construction public Vehicle(eCategory Category, String strMake) { this.Category = Category; this.Make = strMake; } } } Here is the C# for the MainWindow.  A new Vehicle object is created as a member.  In the constructor I set a data-provider in the XAML to this Vehicle object.  There is a button event for showing the values of the controls and objects so I can check the binding. namespace ComboExample { // Interaction logic for MainWindow.xaml public partial class MainWindow : Window { // Attributes Vehicle m_Car = new Vehicle(Vehicle.eCategory.Road, "BMW"); // Construction public MainWindow() { InitializeComponent(); // link data-p

Listview Toggle Visibility of a Textbox based on Data Not Null.

I want to toggle a Textbox to be visible (true, false) contained within an InsertItemTemplate based on the data being Null/Empty.   It Works in the Item Template since it is calling the "select parameters", but once it is in the "insert parameters" on databinds, I am unable to get this to work.  <%# String.IsNullOrEmpty(Convert.ToString(Eval("qu_8")))?Convert.ToBoolean("false"):Convert.ToBoolean("true") %> (works in Item Templates, but not in InsertItemTemplate to toggle a textbox to be visible or not visible). I am using C# in code behind. Thanks in advance -Mark

Binding to a textbox

Hi all,   I'm trying to bind to a textbox in the codebehind but can't figure out how to do it.

Dynamic Textbox List Control - problems refreshing


Ive been stuck on this one for a month:

So I have a custom control that has a list of textboxes, and a button that will dynamically add a new textbox to the list.

 So I have an addTextbox() function, that will do something like

TextbBox t = new TextBox()

 then I add it to the page.  So adding a new textbox works fine, but I have values that I want to put into each textbox and upon each page load, the values get replaced.  What I need to do is get the textboxes from the viewstate so I can use their values for other textboxes, but since they are created anonymously, im not sure how I can do that.  I tried to get the unique name and put all of them into an arraylist, then upon the next page load, load the names from the list, but the unique name isnt unique.  Thanks

Simple WPF ListView Binding Issue


I've uploaded a very simple test project with the issue here: http://www.2shared.com/file/sRVEBh42/KvpTest.html (or here)


The basic problem is, I have a ListView bound to a property on my class. The property is of type ObservableCollection<ObservableKeyValuePair<string, string>>.

I created the ObservableKeyValuePair so I can do two-way binding.


My ListView has 2 columns, Key, and Value. The Value column has a custom DataTemplate which is simply a TextBox, with its Text property setup with a two-way binding (so the user can edit the values of the ObservableCollection<ObservableKeyValuePair<string, string>>.

In my property's setter, I place a breakpoint however it never gets it. The setter of the ObservableKeyValuePair<string, string> is getting hit instead. This seems right, but I need to also propagate that change to the class property my ListView is bound to so I can simply pass the property through to another class and it would contain the changes.

Any ideas how I can achieve this? The sample project is very simple and small if you don't mind downloading it.
