I want to bind an UltraGrid to a generic list of strings using List<string> (c# generic class).
I've set up a BindingSource.DataSource to my List<string> object, but when I hook it up and run my program, the UltraGrid shows a single column bound to the Length property showing the Lengths of my strings instead of showing me the actual list of string data.
If I set a System.Windows.Forms.Listbox or ComboBox to use the same BindingSource, I get the expected list of strings shown.
Why can't an UltraGrid do the same thing? I couldn't find any help on this seemingly simple thing.
Do you have the lates Hot Fix? I'm pretty sure this was fixed.

I'm using NetAdvantage 2008 Vol1 which was just released 2/19. Not even two weeks ago.
There's hotfixes already? I just looked around on my downloads page and there aren't any hotfixes listed for 2008 Vol 1.
Hi,
I just tried this out and it works just fine for me:
private void Form1_Load(object sender, EventArgs e) { //List<int> list = new List<int>(); MyList list = new MyList(); list.Add(1); list.Add(2); list.Add(3); this.ultraGrid1.SetDataBinding(list, null); } public class MyList : List<int> { }
You're right, i've just checked, and it seems a BindingSource issue, our grid is binding thru a binding source 99% of the time, so it looks like it was a problem related to the grid but it looks more related to the bindingsource, since the grid is retrieving it's properties thru this component!
Well this solved this case then, thanks alot! Sorry for loosing your time, we should have test that before even hitting this site!
The BindingSource should not make any difference. If simply using a BindingSource is causing the grid not to pick up the correct fields for a list, then that would be a bug in the grid.
I tried this out with a BindingSource and it still works fine for me, though.
private void Form1_Load(object sender, EventArgs e) { //List<int> list = new List<int>(); MyList list = new MyList(); list.Add(1); list.Add(2); list.Add(3); BindingSource bindingSource = new BindingSource(list, null); this.ultraGrid1.DataSource = bindingSource; } public class MyList : List<int> { }
Hmmm i've copy paste your code in vs.net and it doesn't work, here's my code: public partial class Form1 : Form { public Form1() { InitializeComponent(); }
public class MyList : List<int> {
}
private void Form1_Load(object sender, EventArgs e) { //List<int> list = new List<int>(); MyList list = new MyList(); list.Add(1); list.Add(2); list.Add(3);
BindingSource bindingSource = new BindingSource(list, null); this.ultraGrid1.DataSource = bindingSource; } }
By the way, im still using 8.2 (Which im not sure why since the admin guy install this one and install our key which is supposed to work for 8.3 (maybe the keys are backward compatible not sure about this). Also we are using vs.net 2010 (This is a .net 4.0 project), although i don't think this could cause any issue...
It is certainly possible that this was a bug in v8.2. Are you using the latest service release?
I am testing with the oldest currently-supported version, which is v9.2.
It's also conceivable that Microsoft changed something in the BindingManager or BindingSource that broke this for VS2010. I was running VS2008 when I tested it the first time around.
So I tried it again today using VS2010, and v9.2 and it still seems to work just fine for me. My gird displays a single column with the header "Value", and each cell in the grid contains an int, just like it should.
So my guess is that this was a bug in v8.2. Try getting the latest service release and see if that helps.

Hi Mike,
Could you please tell how to bind if there are more than one band in the grid. I want to bind the grid with separate typed lists for each band. I am trying different ways but unable to bind the grid correctly.
Any help is greatly appreciated!
Thank you,
Bhargavi R.
No problem, i'll get back to you here once i get some time to test this out...
Thanks!
