I am using the GridView similar to a table, where a long note is displayed as wrapped text over multiple lines. The problem is that the row size is not adjusting to display the entire text.
So I'm trying to use the "AutoSizeRows" property b/c my understanding from reading other posts on the forums is that it should do exactly that, but it's throwing a run time error:
rgvNotes.AutoSizeRows =
True
And I get:
System.InvalidOperationException was unhandled

Thank you for writing. I am afraid I could not reproduce the exception. Please provide more information for your scenario or submit a support ticket with a sample application which reproduces the issue. I am looking forward to your reply.

I have the same problem :-(
You need a grid with several rows, so that the right scrollbar is visible.
this.radGridView1.AutoSizeRows = true;
private void radGridView1_ViewRowFormatting(object sender, RowFormattingEventArgs e)
{
if (e.RowElement.IsCurrent)
{
e.RowElement.Font = new Font("Arial", 48f, FontStyle.Bold);
}
else
{
e.RowElement.Font = new Font("Arial", 10f, FontStyle.Bold);
}
}

I used the code you provided and still can not reproduce the exception. I am using the Northwind.Employees table and the vertical scrollbar is visible. Please list the exact settings that I need to use in order to reproduce the crash.

puhh... I'm very happy. I found the problem :-))) That's important for my solution.
Here's my sample code. The error was the "BestFit()" Line and when you clicked in a group AND when the property AutoSizeRows = true! With AutoSizeRows = false it works.
Thats was reason why I'm posted here.
Greetings and Thanks for your fast answer

I tested the code you provided with the latest Q2 release and everything works fine. I suggest you upgrade to the newest version. The new release includes improvements in memory usage and performance and includes a completely new RadDock control.
