Hi Tamir,
Based on my understanding, in your
DataProvider.DataProvider.DS_BringRacks(), it means that DataProvider
namespace contains a DataProvider class whoes DS_BringRacks() method
returns a dataset.
I think you should check if your dataset is generated correctly.
If it is generated well, I think your problem must be the DisplayMember. I
think the "id" field you assign to DisplayMember is not the correctly field
name in the dataset.
Sample listed below, this works well:(I use the default sql server database
to generate the dataset then bind it to combobox)
SqlDataAdapter adapter=new SqlDataAdapter("select * from
jobs","server=localhost;database=pubs;user=sa;pwd= ");
DataSet ds=new DataSet();
adapter.Fill (ds);
comboBox1.DataSource=ds.Tables[0];
comboBox1.DisplayMember="job_desc";
comboBox1.ValueMember =comboBox1.DisplayMember ;
While I change the "job_desc" to "job_des"(Lost one character), then the
combobox will display "System.Data.DataRowView".
If you have anything unclear, please feel free to let me know

| Nop, tried as well to create absolute new dataset - nothing...
| I'm afraid it's because of event looker (I have event onindexchage on this

| dataload...)
|
| What do you think?
