Return value from another window to gridview cell

[Shaimaa]

Hello,

I have a radgridview which i have bind to an ObservableCollection<objects>.
Now i want to insert a new row. I Have the following columns - Countryid | CountryName | Currency.

For the countryid and name i just type in some value in the cell...as for the Currency...i get the value from lookup.

When i double click on the cell Currency - i have a Search screen from which i select the currency.

Now the issue is that on closing the search screen , i can't return the value to the cell Currency.

Does anyone know how we can do this ?
i was trying to set the value of current cell but it did nt work.
gvcountries.Currentcell.Value = "text";

Please giv some hints on how i could tackle this.

Regards
Shaimaa
