.NET Forum / Windows Forms / WinForm Controls / September 2006plus/minus button in a TreeView.
Hi, Is it possible to change the bitmap used to show the plus-/minus-sign button in a TreeView ?? BR Peter You can set the ShowPlusMinus property to false, and then override the OnPaint method in a derived class.

The thing is that the corners of the icon is white, and i want it to be darker or transparent. /Peter On 15/09/2006 in message <#cHcS2M2GHA.1548@TK2MSFTNGP02.phx.gbl> Peter Larsen [] wrote: >Thanks, but i don't want to do any ownerdraw. >The thing is that the corners of the icon is white, and i want it to be >darker or transparent. > >/Peter Pity we don't get the source to the .NET classes, I'm sure we used to with older versions of VS. SignatureJeff Gaines Hmmm. I want to go to New York, but I don't want to leave my home. Sometimes what you need to do and what you want to do in order to achieve what you need to to are 2 completely contradictory things. I guess you'll just have to decide which of the 2 things is the thing that you want more than the other.

I don't want to ownerdraw the entire control just to change one icon. The problem is the icon and it should be fixed there - not by creating new problems. BR Peter > Hmmm.

You could disable the XP visual styles to your application in order to display a transparent plus/minus icon. To do this, C#comment out the line of code 'Application.EnableVisualStyles();' in the Program.cs file if you're using . If you're using VB.Net, right-click the project in the Solution Explorer and choose Properties. In Project Designer, select the Application tab. Clear the checkbox before the 'Enable XP visual styles' option. If this is not what you need, please feel free to let me know.

Hi Linda, What i mean is that it seems like all XP controls are designed to be placed on white backgrounds. Try place a ProgressBar on a dark/black background and you will see 4 white dots in each corner - it doesn't look nice. BR Peter Hi Peter, Yes, this appearance is a feature of XP visual styles. If you don't like it, you may disable the XP visual styles in your program. You could do this by following the steps I mentioned in my previous reply. If you have any concerns, please feel free to let me know. Sincerely, Linda Liu Microsoft Online Community Support Hi Linda, This is not the kind of answer i had hoped for, but i got the message: If i want XP standard controls placed on darker backgrounds, i have to use ownerdraw. BR Peter Hi Peter, You don't have to draw the whole Control, just the plus signs. When you override the OnPaint method, first, call the base class's OnPaint method to draw the Control, then add to it.
