You can put a bitmap on the background, with a gradient.

What if you place a form over the top of the existing form, make it transparent, and draw on that ?

You're hoping to ship part of VS with your app ? That's not gonna work.

underline column caption

I want to underline DataGridView column caption text when user click in it.

I tried

foreach (DataGridViewColumn dataGridViewColumn in grid.Columns) {
DataGridViewCellStyle dgvcellStyle = new DataGridViewCellStyle();
System.Drawing.Font font = new System.Drawing.Font(
dataGridViewColumn.HeaderCell.Style.Font,
System.Drawing.FontStyle.Underline );
dgvcellStyle.Font = font;
dataGridViewColumn.HeaderCell.Style = dgvcellStyle;
}

But got exception probably since debugger shows that

dataGridViewColumn.HeaderCell.Style.Font

is null.

dataGridViewColumn.HeaderCell.Style is not null.

How to fix ?

Exception details which occurs:

System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
Source="System.Drawing"
StackTrace:

Preview a Form

Hello!

Is there any way to preview how my form and the controls on it would look like, before actually running it? I tried to visualize it in the designer itself by docking the other windows, but was just curious if VS 2005 had some 'Preview option' to view the form on the Full screen.

VS probably has a full screen mode, otherwise, that's precisely what the designer is for.

that's an Object Oriented Programming beginners issue. You need a C# book for beginners. Trying to learn programming fundamentals over the internet forums is not an efficient means of doing that.

Well if I were to decide to insult you in this context it would be because I do know how to do that and have known since about 1992. So what's your reason?
