can anyone tell me why this same code works on a normal windows
platform but when used in compact framework application produces an
argument exception on setting either the valuemember or displaymember

ds = new DataSet();
string filePath = @"\Program Files\crp3\airf2.xml";
ds.ReadXml(filePath);
this.comboBox1.DataSource=ds;
this.comboBox1.ValueMember="airf2.ICAO";
this.comboBox1.DisplayMember="airf2.AIRFIELD";


TIA

John Murray

Hi John:

I don't have the XML file but I use the identical code in many of my apps
and don't have a problem. My guess is that it's the tablename airf2 that's
not being recognized. I'd double check the table count and verify the table
name. You could also just set the source to the table and use just the
field names....
this.comboBox1.DataSource=ds.Tables[0]; //Assuming there's only one table
this.comboBox1.ValueMember="ICAO";
this.comboBox1.DisplayMember="AIRFIELD";

If you want to send me a copy of the xml file, I'll be glad to test it under
both environments and see what I can find... but I'm guessing it's the
tablename.

If you want to send it to me , zing it to my work address wryan At

John,

It's not working because it's not supported. You can not use dots in CF
data binding, anything like "airf2.ICAO" will result in ArgumentExeption.

To make it work, bind to the table, not to the DataSet. This would allow
you to remove dots and will work just fine.

Best regards,

Ilya

Many thanks William - I have another suggestion about using ( or not)
