• How can you speed up the display of WinForms in C#?

  - by Craig Johnston

  How can you speed up the display of WinForms in C#? I am finding that forms are being painted quite slowly, even if the window is being 'reactivated' (ie. switched to) after having been already loaded. Other languages seem to be render forms a lot quicker. Is there a way to speed things up? Using C# in VS2005.

• Any picture Gallery Control for .NET 1.1 in WinForms?

  - by Romias

  I need a UserControl to display pictures as a Gallery in Winforms. I have my pictures as a Image Collection but no problem to change to fit Control capabilities. It could be nice if it is for .NET 1.1 but since I'm planning to migrate all our code to 2.0 if the control is in that framework it could be useful in the future If it is free much better :) Does any of you know a control like this? Thanks!

• Databinding with Control Properties in Winforms: Bind Enabled to state of Combobox?

  - by bwerks

  Hi all, I have barely any experience with WinForms, but I'm fairly sure that this is a simple task. I just need to enable and disable the Enabled property of a textbox based on the SelectedIndex of a ComboBox. Can this be done in the designer using DataBindings, or am I required to write a handler of some kind?

  - by Allen

  Not sure if this is a bug or if i'm just missing something but I cannot for the life of me figure out how to get my cursor back in the winforms designer in visual studio 2010. I opened up an existing project and added a group box, now my cursor is stuck drawing group boxes. I just want the simple pointer cursor back but nothing I do seems to bring it back. I almost expected it to be on the toolbox under "Cursor" but its not.

• Best aproach for working with Time in C# WinForms?

  - by MadBoy

  I'm trying to make a field where user will enter amount of time per day he/she spent on a project per day. It can be from 30 minutes to 8 hours. Is DateTimePicker with CustomFormat hh:mm best choice for this? Or there's better alternative for WinForms C#? Maybe TextBox or MaskedTextBox with special settings?

• Which one has a faster runtime performance: WPF or Winforms?

  - by Joan Venge

  I know WPF is more complex an flexible so could be thought to do more calculations. But since the rendering is done on the GPU, wouldn't it be faster than Winforms for the same application (functionally and visually)? I mean when you are not running any games or heavy 3d rendering, the GPU isn't doing heavy work, right? Whereas the CPU is always busy. Is this a valid assumption or is the GPU utilization of WPF a very minor operation in its pipeline?

• How to build form completion/document merge application with Winforms or WPF?

  - by Mike

  I need to build an application that accepts user input data (such as name, address, amount, etc.) and then merges it with a pre-loaded document template (order form) and then prints this merged document. I can use Windows Forms or WPF for this project. Any suggestions on how best to approach this? I'm experienced with Winforms development, but don't have any idea how to handle merging the data to the document for printing.

• Adding Custom Fields to RadScheduler for WinForms Appointments

  When using RadScheduler for WinForms, it will almost always need to be customized in some way. This could come in the form of custom dialogs, context menus, or even custom appointments. In this blog entry, I am going to explain the steps required to add a custom field to RadScheduler. Click here to download the source code and follow along... Adding Custom Fields to Appointments In this example, a custom field for Email will be added to the Appointment class being used by RadScheduler. The process of accomplishing this involves five simple steps. Step 1: Add a Custom Field to the Data Source In order to display a custom field in RadScheduler, the field will first need to already exist in, or be added to the data source. In this example, the database being used is based on the structure of the SchedulerData sample database included with the installation of RadControls for WinForms. Figure 1 shows the structure of the database. Note ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How do I get the C# Winforms Webbrowser control to show PDF content embedded in the html file as bin

  - by uniball

  I am using a Winforms webbrowser control to display HTML content stored in my SQL DB table. However, some of my contents are PDFs which I intend to store as binary data in the SQL DB and feed to the Webbrowser control. I wish to avoid the hassle of storing the binary content in a temporary file on the client machine and then create html container code to reference this temporary PDF file. Is there a way inwhich I can embed the PDF binary content into the html directly and show this html on the webbrowser control directly? I found these previous threads referring to a COM 'hack'. Is there a simpler, easier way? Thanks! http://stackoverflow.com/questions/290035/how-do-i-get-a-c-webbrowser-control-to-show-jpeg-files-raw Thanks, uniball

• Abstract base class for Winforms-Control and VS2008 Designer support?

  - by BeowulfOF

  Hi, I engadged a problem with inherited Controls in WinForms, and need some advice on it. I do use a base class for items in a List (selfmade GUI list made of a panel) and some inherited controls that are for each type of data that could be added to the list. There was no problem with it, but I know found out, that it would be right, to make the base-control an abstract class, since it has methods, that need to be implemented in all inherited controls, called from the code inside the base-control, but must not and can not be implemented in the base class. When I mark the base-control as abstract, the VS2008 Designer refuses to load the window. Is there any way to get the Designer work with the base-control made abstract?

• Can checkboxes be removed from a .NET WinForms ListView at runtime?

  - by James

  Is it possible to remove the checkboxes from a .NET WinForms ListView control at runtime? The following code appears to have no effect when '.Checkboxes' has initially been set to 'true' and the control has rendered onto a form with checkboxes available for each list view item: // C#: testListView.BeginUpdate(); testListView.Checkboxes = false; testListView.EndUpdate(); Is there a method that must be called to enact this change? What is the use of providing the .Checkboxes property when it defaults to 'false' and only has an effect if set to 'true'?

• How do I "Fire and forget" a WinForms Form?

  - by Neil Barnwell

  What's a good technique to create a WinForms Form instance, display it (non-modally) but not have to keep a reference around to it? Normally, as soon as the variable goes out of scope, the form is closed: var form = new SuperDuperForm(); form.Show(); // Form has probably been closed instantly I don't want to have to keep track of instances of the form, I want it so that when the user closes the form, it is disposed. One idea I've had that I'm going to implement is a kind of controller that I use to open and display forms, that will keep track of them and monitor when they are closed via callbacks. I'm just wondering if there are any neat tricks to get away without that. Any ideas?

• How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

  - by Ivan

  I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

• Which is the best and appropriate way to write the code in Winforms ?

  - by Harikrishna

  What is the best way to write the code ? (1) Like directly writing the code in the button_click() event. or (2) Make the function of that code which I write in button_click() event and write this function in one class and then that function I should call in the button_Click() event.Like is it called three-tired approach to write the code ? Like in button_Click() event I write the code to save the records in csv file from datatable.So I should write that code in button_Click() event or I should make one new function and one new class and write that code in that function which is the new class and calling that function in button_Click() event. This is only one example but I am talking about all the code written in my application that which is the appropriate and best way to write the code and what are the benefits ? Note that I write the code in Winforms with c#.

• How do you organize your projects?

  - by Sergio Tapia

  Do you have any particular style of organizing projects? For example, currently I'm creating a project for a couple of schools here in Bolivia, this is how I organized it: TutoMentor (Solution) TutoMentor.UI (Winforms project) TutoMentor.Data (Class library project) How exactly do you organize your project? Do you have an example of something you organized and are proud of? Can you share a screenshot of the Solution pane? In the UI area of my application, I'm having trouble deciding on a good schema to organize different forms and where they belong. Edit: What about organizing different forms in the .UI project? Where/how should I group different form? Putting them all in root level of the project is a bad idea.

• Listening For and Raising Events in the BLL

  - by OneSource

  I'm working on a WinForms .Net Recording App and I have a RecordingMgr in my BLL to listen for new events captured by another class. I want to display the events in my UI and I'm stuck as to what's the best way to do this. I can think of a few scenarios to handle this but all of them seem sub-optimal: Listen for and handle Recorded Events in both the UI and in the RecordingMgr After receiving the event in the RecordingMgr, raise it again so that the UI can pick it up Create a variable in RecordingMgr (e.g., a BindingList) that the UI can bind to and update it when an Event is received Ditch the RecordingMgr and just put the event recording logic in the UI What's the best approach? Something above or something else?
