     Hi everybody.
      My database is oracle. and i use sqldatasource to access database. My RadGrid's datasource is the sqldatatabase. the oracle database have no bool datatype. So some fields i used the number 0 and 1 instead. the 1 is true and the 0 is false.  in the radgrid. I show the field by checkbox. the code like this:
  <telerik:GridTemplateColum>
     <ItemTemplate>
         <asp:CheckBox id="chkBool" checked='<%# DataBinder(Container,"DataItem.SomeField").ToString()=="1"?true:false %>' />
    </ItemTemplate>
  </telerik:GridTemplateColum>
     And In my edit form. I also use the CheckBox like this 
 <asp:CheckBox id="chkBool" checked='<%# DataBinder(Container,"DataItem.SomeField").ToString()=="1"?true:false %>' /> 
   so  how can it automatic update or insert the data to oracle?
     And when I want to Update a row by edit form, How can i update the data? And How do i write the Sqldatasource's updatecommand?

Hello,

You could try by wiring the UpdateCommand event of RadGrid and there overwriting the value passed by RadGrid to the database. The syntax for doing so would be (depending on the checkbox value):
LocalTestDataSource.UpdateParameters["ColumnUniqueName"].DefaultValue = 0;

In case you decide to switch to manual update you can look at the code sample in the Insert/Update/Delete at database level with queries help article.
