Inserting data into database using button click event of rowdetailstemplate in radgridview of silverlight using mvvm

[Spoorthy]

Hi,

Please let me know how can I insert data into dataabase by clicking a button in RowDetailsTemplate of RadGridView for Silverlight using mvvm.

Existing Problem:

I am able to insert the textbox values into database which are outside the telerik radgridview using mvvm.But when I place the textboxes and button inside the RowDetailsTemplate of RadGridView using mvvm,the database is inserted with all null values.

thanks in advance
