Empty WinForm frezzes on show?

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :.NET Framework
Hi! I have a static WindowController where I can do the following : Open LoginForm Open MainForm Open MidiFormInMainForm When application starts it will Open LoginForm with WindowsController. This is done by instanciate the form, binding it to a SuccessfulLogin event and then run Show(). Everything works grate so far. When hitting the login button(in LoginForm) a separate Thread will be created with ThreadPool.QueueUserWorkItem. ThreadPool.QueueUserWorkItem(new WaitCallback(LoginUser)); This Thread will validate the form(with begin invoke), send the login information and if success then trigger the SuccessfulLogin event and finaly close the login(all this from within the LoginForm). When the WindowsController get the SuccessfulLogin event it will run this simple code :   Form form = new Form(); form.Show();   This will open a empty form but it will frezze, it is not even possible to move the window? If we change the code to form.ShowDialog() then it will show properly but we do not want it to be a dialog. I supose that this could have something to do with the threading and maby also that the WindowController is static. Pleas advice. BestRegards

WPF DataGrid does not show new row on empty linq query

I'm using Linq to Entities and bind a linq query to the WPF 4 DataGrid datacontext.  The linq query look something like this:                  var query = from s in this.db.Customers                         orderby s.Name                         select s;             private ContextEntities db = new ContextEntities();             private BindingListCollectionView View;             this.View = ((BindingListCollectionView)CollectionViewSource.GetDefaultView(query));             this.DataContext = this.View; If my Customers table does not have any record, the DataGrid does not show any row for user to add.  I have CanUserAddRows set to true.  I found another post that address this issue but it say to create a new entity type.  http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/cdc0fb6f-2335-42e2-98d7-4bd73ffffc8c My project

How to show label when TreeView is empty?


Sometimes I feel that DataBinding and Triggers defined in xaml is just trying to fight me.

I have this really simple case where I have a UserControl with a TreeView and a TextBlock. I want to show the TextBlock only when the TreeView is empty.

In code this would be one or two lines of code, but I’m determined to hook it up in xaml, but so far, no matter what I try it doesn’t work.


I even tried to expose the Items as a property on the control class itself – but I could bind to that either.


How would you do this in xaml ?





How to show HTML Content in Winform



Am trying to create an RSS feed reader. And when i read the data from RSS, i get HTML content. Am clueless as how can i show the content. In fact, there is web browser to show the content, but not interested in the WebBrowser. Is there any other control like RichTextBox which can hold the HTML data and show the text as is from Web.

Am trying to use all the Unicode data content and UTF format. This may not be for the WPF forum, but i couldn't find the Windows forum, hence is here.

WPF toolkit DataGrid does not show new row with empty collection



I have exactly the same issue present on the post: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/cdc0fb6f-2335-42e2-98d7-4bd73ffffc8c

However, the answer is still unclear to me, confusing. So I would like to clarify what do I have to get the new blank row on the datagrid.

My custom collection is called PieceUIObjects (derived from ObservableCollection) containing PieceUIObject objects.

What do I have to change in my collection in order to properly "inform" the datagrid how my object is so that the new row is added on it when the collection is initialized with no elements?

Show grand total running total in GridView Footer

In many scenarios we need to display Running total as well as Grand total in GridView footer. In this post i will try to explain in an easy way that how we can display running total & Grand total in a GridView footer combindly. To explain this solution using an example here i use a sales order report. The report contains all sales order amount in a tabular way. I will use a GridView to display sales order amount and use GridView footer to display Running total & Grand total. Let we have a customer table with id and name column plus an orders table with OrderID,CustomerID,OrderDate & Amount. Now our goal is to show all customers order with amount as well as page wise running total & grand total. Note that running total is necessary when you enable paging in a GridView where as Grand total is always you can consider.

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

I've created a SetupWizard, but can't get it to show the Icon for the shortcut on desktop and program menu. The installation goes fine without any errors, the only problem is the icon.

Any suggestions will be very much appreciated.

Empty template support for GridView


Just add the following to support the empty text in the GridView.


protected override void RenderContents(HtmlTextWriter writer)
	if (Extender.AdapterEnabled)
		GridView gridView = Control as GridView;
		if (gridView != null)
			if ((gridView.Rows.Count == 0) && !String.IsNullOrEmpty(gridView.EmptyDataText))
				writer.WriteAttribute("class", "AspNet-GridView-Empty");

Example of tag to be added to the css
.NiceGridView .AspNet-GridView div.AspNet-GridView-Empty
