Can it possible to create a combobox control which always set datasource, 
 
displaymember and valuemember peoperties? 
 
For example: 
 
public partial class CurrencyCodeComboBox : ComboBox 
 
{ 
 
public CurrencyCodeComboBox() 
 
{ 
 
InitializeComponent(); 
 
if (!this.DesignMode) 
 
{ 
 
try 
 
{ 
 
this.DisplayMember = ColumnNames.CurrencyCode; 
 
this.ValueMember = ColumnNames.CurrencyCode; 
 
this.DataSource = CommonEntities.Currencies; 
 
} 
 
catch { }; 
 
} 
 
}

I currently have an application that uses the Paint event to Merge Columns 
 
of the DataGridView when the data in adjacent cells are equal. I have two 
 
questions regarding this : 
 
1) What is the easiest way to determine the last column that in in the 
 
displayable in the user area when the form is resized (need this to center 
 
the text when all the columns are not currently displayed). 
 
see below (Should use last column + width of that column that is actualy 
 
displayed). 
 
2) Some o ...

I created a complex custom control using Visual Studio 2005 in C#. The 
 
control has numerous properties, some of which Visual Studio cant seem 
 
to create designer code for when I set its value in the property 
 
browser. Below is the property that is giving me the most trouble in 
 
the designer. 
 
[DefaultValue(true), Browsable(true)] 
 
public bool ShowCursor 
 
{ 
 
get { return showCursor; }

{

{ 
 
cursorTick = new Timer();

VB 2005 (.Net 2.0) / Win XP Pro - SP2 
 
The ListView contains 3 columns and on load the first 7 rows are visiable. 
 
The first 7 rows are of the correct Row Height/Col Size.  As you scroll down, 
 
the next rows appear to NOT be of the correct Row Height OR there is an 
 
issue with a paint event as there is a line that runs thru the row. 
 
How can I correct this appearance?  Is this a bug?  (Is it possible to 
 
include a screen shot to show what I am talking about?)

Hi all 
 
I've created a control dereiving from another control. This controls has 
 
data binding ability. Is it possible to be notified in code when the 
 
databinding actually is completed? I need this in order to perform some

I have a UserControl that has worked properly for nearly a week, both 
 
in the Designer and at runtime. However, even though I have not made 
 
any changes to the control, today the Designer does not like it. 
 
My component encapsulates a ListView, and has the following property: 
 
namespace Ui 
 
{ 
 
public partial class BigMenu : UserControl 
 
{ 
 
// ... 
 
public ListView.ListViewItemCollection  Items { 
 
get { 
 
return theListView.Items; 
 
} 
 
} 
 
// ... 
 
private System.Windows. ...

I have a very simple UserControl (derived from 
 
System.Windows.Forms.UserControl) that contains several ListViews. The 
 
UserControl exposes a single public property: 
 
public ListView.ColumnHeaderCollection Columns { get {...} }; 
 
When I use VS2005 designer's proprtygrid for that UserConrol to add new 
 
Colums to the Collection everything works fine: The form that contains 
 
the UserControl gets new members ( private 
 
System.Windows.Forms.ColumnHeader columnHeader1, ...) in the

How do I add an additional column (to pad the width of the datagrid). 
 
I've created the column in the tablestyle, but it wont display unless I 
 
give it a mappingname.  And if I do that, then the column isn't blank. 
 
So how do I get a blank column?

Hi, 
 
I'm developping a user control and this user control started to behave 
 
weirdly today for an unknown reason. Actually, when I run the application, 
 
everything is right, but when I edit my form, I can do any changes to the 
 
control's properties and when I select a control on the page, the property 
 
pane does not react to anything, when I double-click on something to 
 
implement an event or something that would make the gui go to source code, 
 
it does not react (tought the Event' ...

Hi, 
 
I'm developing a custom winforms control that uses the Graphics objects to 
 
draw itself to the default UserControl panel. The problem is, even if I draw 
 
some very basic things (like 2 rectangles), it flickers when I move it...  I 
 
mean, I can see some tearing in the control's image (or whatever is 
 
painted).  I tried using this.SuspendLayout() and this.ResumeLayout, but 
 
nothing changed, there's still tearing... 
 
Does anyone have any solution to this problem?

Greetings, 
 
I have created a very simple application that loads a web page from a URL 
 
and then parses it for all the href's.  I try to build an internal data 
 
structure of the links URL and the text in the <a /> tag using a custom 
 
object that has those two properties and a generic List<T> structure. 
 
The problem I'm hacing is that, in the webBrowser_DocumentComplete event, 
 
when I add a structure to the List<...> then the webBrowser_DocumentComplete 
 
event fires multiple ...

Hi there, 
 
I have an application that consists of a tcp listener that runs in a loop on 
 
the user's PC.  When the listener gets a connection, it acts on the data- 
 
which may or may not cause a form to display- then goes back to listening. 
 
As there is not always a UI form object instantiated, I created a custom 
 
application context, instantiated a notify icon, and associated a 
 
ContextMenuStrip to it in order to give the user control over the application

Hi all,

can I do an alignment like this?

I'm forced to use .Net 1.1 for now, and have had moderate success with 
 
the quirks of the DataGrid.  However, a couple of issues I have are 
 
with regards to sizing.  It seems that with horizontal sizing, I seem 
 
to be able to keep a mininum horizontal size that I want, but can't 
 
seem to stretch wider if the user maximizes the app.  The grid will 
 
stretch horizontally, but the columns wont and so there's a blue blank 
 
area where the grid grew to the right.  I'd like to either keep th ...

Hi, 
 
In the toolbox of VS 2005 all of the icons of the controls like 
 
"button", "checkbox" has turned into an icon which is shown at the 
 
error provider (red O with a white ! in it). Could someone tell me what 
 
happened en how to correct this problem?
