Morning,
I've spent ages trying to sort this problem and I've got nowhere. I was just wondering if anyone here had some across it before.
The best way to describe it is with picutres
with problem[^]
As you can see on the above picutre the display is "mangled", showing through to the window below and generally looking corupt.
If I force a refresh (this.Refresh()) then it renders correctly as shown on:
without problem[^]
As the problem seems to occure everytime the data on the form is changed in anyway (add to table, resize form etc) I don't really want to manually force refreshes all the time in order to sort it.
At first I thought this problem was due to graphics card/driver issue on my development machine but after testing this on 4 other machines (all different specs) I'm not so sure as the problem was present on those machines as well.
Any ideas would be very welcome.
Thanks
Sam

Just a bit more info.
The DataGridView on the form is one that I have subclassed from System.Windows.Forms.DataGridView
It has the following handler declared in its ctor.
this.CellFormatting +=new DataGridViewCellFormattingEventHandler(DGVEnhanced_CellFormatting);
If I comment this out then the problem goes away. If I leave it in (even if the DGVEnhanced_CellFormatting function is empty and does nothing, then the fault resurfaces. Very strange...

I have wizard kind of Windows Application with Forms having Prev and Next buttons. Currently i have set the Location for all the Forms on Form_Load() method using this.Location = new Point(100, 100);
Now my requirement is that when using "Extend my Windows desktop onto this monitor” setting in Display/Settings Properties, the form should stay in the user’s selected monitor. When i go to the Next form it defaults to the main monitor.
I tried removed the size setting on Form_Load but when i navigate to the next/prev forms the location of the form is not properly set. It randomly positions itself.
How can i do this?

I'm not sure if I'm understanding you fully, do you mean you're using dual screens and you want the form to load on the screen it did last time?
There are a number of types of default form position.
Look at the form's StartPosition property.

Yes that right. I'm using dual screens and i want the next form to load on the screen as how the previous form occupied 2 screens. How can i do that?

Hi,
Below you see the string array which I am populating BUT I would like to populate dynamically becuase the dataset where the data is coming from may have different number of records each time.
Could you please correct the preferred method mentioned below as it seems I can not use .Add to add into the string array.
p.s. I do not want to use an arraylist
Thanks
Present method:
private string[] _securities = null;
_securities = new string[]
{
"XS0166639566 corp cusip","XS0184546371 corp cusip", "XS0307767474 corp cusip"
};
Preferred method:
private string[] _securities = null;
foreach (DataRow row in dsSecuritiesDetails.Tables[0].Rows)
{
//something to add here to add to the string array...
//i.e. _securities.Add(row["field2"].ToString()) + " corp cusip";
}

string[] _securities = null;
_securities = new string[]
{
"XS0166639566 corp cusip","XS0184546371 corp cusip", "XS0307767474 corp cusip"
};And then, whenever you need to add a string:
Array.Resize<string>(ref _securities, _securities.Length + 1);
_securities[_securities.Length - 1] = "The new string";
</string>

No, please don't do that.
There is no way of resizing an array in .NET. What the Resize method does is to create a new array with the desired size and copy all the data from the old array.
If you do this in a loop, the performace degrades exponentially to the number of items.

It was not about performance, why are you so upset?
He could use the StringCollection, but he simply wanted to use the string[] (I don't know why, ask him for that  ). I just offered a solution to what he wanted.
Peace

I'm not upset. I just wanted to point out that the solution is generally a bad method to use.
Eventhough the question didn't mention performance, some solutions scale so badly that they should never be suggested without explaining what happens when you use it with more than a minimal set of data.
Mircea Puiu wrote: I just offered a solution to what he wanted.
No, you offered a solution to what he thought that he wanted.
Just because he asked for it doesn't mean that it's the method that he should use.
People often don't know what to ask for. It's quite common that they ask for the solution that they think that they should use rather than a solution to the actual problem that they have.

Use a list instead of an array:
private List<string> _securities = new List<string>();
foreach (DataRow row in dsSecuritiesDetails.Tables[0].Rows) {
_securities.Add(row["field2"].ToString() + " corp cusip");
}

Hi,
use a collection (StringCollection, ArrayList, or generic List< string>) as others
indicated.
Then convert it to an array if you really need an array. ArrayList and generic List
have a ToArray() method for that purpose.

Hi all,
is there a way to cast a System.Windows.Controls.UserControl (.Net 3) to a System.Windows.Forms.Control (.Net2) ?
I have a Plugins system and I'm trying to plug some .Net3 components
Assembly l_assembly = Assembly.LoadFrom(AssemblyName);
Type l_type = l_assembly.GetType(TypeName, true);
Control l_itemControl = Activator.CreateInstance(l_type) as Control;
here I catch an Exception when I load a "Custom Control Library (WPF)"
Thanks

No, there isn't. You cannot use a .NET 3.0 component in a .NET 2.0 app. You cannot load two different versions of the .NET CLR runtime into the same process.
Also, .NET 2.0 does not support WPF, so you can't do this at all.
You can do the opposite though. You can load a component that was developed under .NET 2.0 in a .NET 3.0 runtime app.

I have a form with multiple TextBox controls and few other controls like comboBox, checkBox etc. I'm trying to implement Undo functionality for all the controls in the form. I'm using Push & Pop operations of Stack to store the control values.
My question is regarding the TextBox control. I would like to know on which event of TextBox control i can save the Text in the stack. If i use TextChanged event, then this event is triggered on each character typed.
I also know that TextBox Base provides Undo functionality but i dont want to use that, since my form contains multiple TextBox and other controls as well. And i would like to perform the Undo operation in sequence. Please help!

You could use Validating or MouseLeave event to check if the text has changed and store new value in stack

Hi guys
[The senario]
i have a form (FrmUsers) that selects some columns from my userTable and then databinds it to a DataGridView on creation
when the user double clicks a row in the datagrid view an instance of (FrmAddUser) displays with the selected users details filled in
then when you close (FrmAddUser) after editing, the user the data is updated to my db
[the question]
how do i tell (FrmUsers)with the DataGridView that instantiated the AddUser Window that it has to redo the data binding as to reflect the changes?
thanx
