I'm sure this is a simple problem and i'm probably leaving some important step out but i've not found it it.

I have a radgridview that has a childgridview all setup. 
On of the columns in my childgridview is a gridviewlookup column.

I created a dataset with one table and two columns.
I have populated the columns with Yes and No.

I then set the gridviewlookup columns' datasource, display member, and value member to their respective columns.
When I run the application the dropdown boxes are populated correctly, but I have a problem when i select one of the items.
Nothing shows up in the gridview when I move to the next field or the next row.  If i go back to the field and click the dropdown item it shows up, but does not stay when I move off that field again.

Is there something that i have done wrong in the setup of my column?

Hi Craig,

Adding a lookup column containing yes and no values is easy. Here is a sample:

DataTable tablec = new DataTable(); 
tablec.Columns.Add("value"typeof(bool)); 
tablec.Columns.Add("name"typeof(string)); 
tablec.Rows.Add(false"No"); 
tablec.Rows.Add(true"Yes"); 
 
GridViewLookUpColumn combo = new GridViewLookUpColumn("Option1"); 
combo.DataSource = tablec; 
combo.DisplayMember = "name"
combo.ValueMember = "value"
this.radGridView1.Columns.Add(combo); 

We assume in the sample above that the Option1 column contains boolean data.

I am not sure about the circumstances that may cause this behavior. So, could you please open a support ticket and send us your code. This way I will be able to investigate the issue and find a solution.

I am looking forward to your reply.

Sincerely yours,
