Filling DataRow[] into combobox

Hi,
I do this:

this.comboBox.D ataSource =
myDataSet.Table s["receivers"].Select("locati on_key = " +
selectedLocatio nKey);
this.comboBox.D isplayMember = "text";
this.comboBox.V alueMember = "subcustomer_lo cation_key";

but get an exception when setting the value member. Unfortunately there
is something wrong with my debugger so I can't see what is in the
exception. I am sure that the columns are named "text" and
"subcustomer_lo cation_key".
I have also tried with the table name: "subreceivers.t ext" and
"subreceivers.s ubcustomer_loca tion_key". The same thing happens.

How do I refer to the columns of the data rows in the DataRow array so
that the combobox understands it?

Best regards,
Kim

Hi Kim,

Try loading the data into a new DataView class and use the RowFilter
property instead. You can bind to the DataView directly.

Hi,

What is wrong with your debugger?
the code seems to be ok but if you do not know what is going on is a little
difficult to know the reason.

Also a little more detail could help, what exception u r getting and where?

Hi Kim,

I shouldn't have wrote "loading the data" since the DataView doesn't contain
any data at all, it just wraps the specified DataTable. In other words, you
should just create a "view" of the data that you want - using a DataView
won't actually copy the data into a new object.

DataView view = myDataSet.Table s["receivers"].DefaultView;
or
DataView view = new DataView(myData Set.Tables["receivers"]);

view.RowFilter = "location_k ey=" + selectedLocatio nKey;

comboBox.DataSo urce = view;
comboBox.Displa yMember = "text";
comboBox.ValueM ember = "subcustomer_lo cation_key";

Also, you should think about strong-typing your DataSet.

Hi Dave!

Thank you for your help - it works. I had forgotten that the DataView
existed :-)

Hi Ignacio,
I think I have to rephrase the problem with the debugger.

I am developing software for a Windows CE 4.2 PDA. When I run the
software on the PDA from Visual Studio 2005 in debug mode and get an
exception, the contents of the exception can not be shown because some
sort of debugging information is missing.

To make the software made in VS2005 run on the PDA I had to install the
..Net compact framework 2.0 manually. I think somehow the missing debug
information is related to the installation of the .Net framework.

Best regards,
Kim

I had never need to install the framework manually, it's always installed
from the IDE when you run the app.

I think you have something wrong with your dev. environment.

Hi again,

I get the message:
"An error message cannot be displayed because an optional resource
assembly containing it cannot be found"
whenever I get an exception.

It IS necessary to install the .Net framework 2.0 manually:

Hi,

This seems like the old "resource assembly" error in 1.1, maybe is the same
one.

Check the blog of the CF to see if there are answers there.
