hi all
I have a datagrid and another datagrid in the rowdetails. When 2 or more rowdetails are displayed, there is problem with scrollbar.
The scrollbar will not disappear when the row detail is collapsed using a button placed in the rowdetails..Please help me if anybody has the solution.
the code to Collapse the rowdetail is as follows:
private void CancelButton_Click(object sender, RoutedEventArgs e)
{
StackPanel panel = (((sender as Button).Parent as Grid).Parent as StackPanel);
DataGrid grid = panel.Children[1] as DataGrid;
DataGridRow row = DataGridRow.GetRowContainingElement(grid);
row.DetailsVisibility = Visibility.Collapsed;
}
thanks in advance..

is it possible to know the method used by dotnet libraries. i m using getbezierpoints method in dotnet to get the bezier points of a stroke. but not sure if dot net is using quadratic bezier points or cubic bezier point or something else. my further analysis depends on the method used by them. i asked the same question 2 days back n was suggested to seek help of reflector. unfortunately reflector is not able to give the code behind. is there any other way out. pls help

Hi,
for such questions there are IMO three possible answers:
- documentation
- reflection
- experiments
I would spend 10 minutes on documentation, try reflection for 10 minutes, then start a series of little experiments, trying out some extreme cases since those are most likely to show the differences.

AFAIK string.ToString() is a waste, it just returns
string<br />

For a very long time now I've been having a problem with making an icon appear on the top-left part of my form. I have created a .ico file and it works for my .exe icon but whenever I try it on my icon property of my form it doesn't work. Anyone have any ideas why I'm having this problem?

An icon file can contain icons in a number of different sizes. You probably are not including one in the size needed for the corner of the form ( I am guessing 16x16 or 32x32 )

As Christian said, ICO files can contain several icons at different sizes (but meant to represent the same thing). Which "sub-icon" gets used depends on the situation AND the Windows version.
And Vista introduced new sizes.
This[^] and this[^] gives some details.
I never encountered a situation where an icon wasn't showing; I usually design it at 32*32 and that seems to work for me every time (that is on XP and Vista). However the favicon.ico shown in a browser's address bar has to be 16*16.
On XP hovering an ICO file shows a tooltip, which mentions the size iff there is only one. Don't know for Vista.

Are you using Visual studio to create icon? If yes I would suggest use some other software to create the icon. I struggled with the same kind of problem,but got rid of it using some freeware icon generator tool(I do not remember the name of that software). you will get it on the net for free

Personally, I use IcoFX. It's freeware and has many useful features (such as extracting icons from existing files).

I use IcoFX if that's any help
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)
Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)
Why are you using VB6? Do you hate yourself? (Christian Graus)

Well thank you so much! It turns out that with IcoFX the icon works well.

Hi,
I have a winform that has a grid linked to a bindingsource. The winform also has a usercontrol on it that also contains databound data linked to the same datatable but via a different bindingsource.
There is a definite need to have the separate usercontrol although life would be much easier without it <sigh>. The usercontrol is loaded onto the winform as a module contained within the winforms tab pages collection.
Anyhow, what I need to do is use the winforms grid as the navigator for the usercontrols binding source.
I have tried everything I can think of, the 'easiest' being to change a static variable on the usercontrol and then have a static method on the usercontrol change the bindingsource position but the bindingsource itself needs to be made static and that's not possible as far as I know?
Can someone come up with some code that will do the trick.
Thanks.

I am working on something that passes a DataGridView to a used control which then accesses the bindingsource of the DGV. I do this by having a public property on the UC of type DataGridView and passing the DGV on form load. I imagine you could do the same with a bindingsource.

Hello I'm new to C# so you might have to bear with me a little bit but here is my problem. I am trying to make a windows form so that when you press a button, all the buttons disappear from the form. When that happens I am trying to make a different button take its place. You might find this a strange thing to do... but I have my reasons  . This is as far as I have gotten.
Making a new button...
Button newButton = new Button(); (tell me if this is even works, because I'm not really all that sure if it does).
And that's all I can come up with. I've tried really hard to make that button appear after the others ones are disposed and I THINK it might have something to do with newButton.Location.X/Y. But that's just a guess. So it would be greatly appreciated if anyone could offer me any help.
I do not ask for code I simple ask for a little guidance to my next step.
Thanks, Nik!

After you create the button Button newButton = new Button() you have to set its x and y coordinates, width and height, and add it to the form: this.Controls.Add(newButton);
|
|
|
|
|
Well I thank you greatly for that much of help and I must say that it helped but I am not sure how to set the X and Y variables. I have tried newButton.Location.X, but when I try setting it equal to an int it says that I can't modify the return variable of Location because it is not a variable. Do you know a way to go around it?

It probably returns a struct (Point), modifying a field of the struct would be kinda useless since as soon as you leave the current scope that struct will be gone (or even if isn't, it's not the same struct as the control has, but a copy)
So, what should work: copy the Location to a local, change the X, assign it back to newButton.Location.
hey, who downvoted this 
It would work. Nothing bad about it either.

Hi,
to set the location of a Control do one of these:
myControl.Location=new Point(x,y);
myControl.Bounds=new Rectangle(x,y,width,height);
Both Location and Bounds are structs, i.e. value types; gettin such struct and modifying it won't cut it, you have to provide a struct with the new values.
