Update Master GridView with updates in Details View

[Jeronimo Bertran]

Hello,

I have create a master/detail using a GridView and a FormView. My
DataSource for the detailed FormView is linked to the GridView by the
details ObjectDataSource whiche looks like the following:

<asp:ObjectDataSource ID="ObjectDataSourceEventDetails"
runat="server" SelectMethod="SelectEventDetails" TypeName="EventData"
UpdateMethod="UpdateEventDetails">
<SelectParameters>
<asp:ControlParameter ControlID="GridViewEvents" Name="eventID"
PropertyName="SelectedValue" Type="Int64" />
</SelectParameters>
</asp:ObjectDataSource>



When I update the record on the FormView by ussing the FormView.UpdateItem,
the modified item is shown on the form view but the changes are not
reflected on the master GridView. Is there some way to do this?

Thanks,

Jeronimo Bertran

Hi Jeronimo,

Thank you for your post!

Are the GridView and FormView binding to the same DataSource object?

Normally data-bound controls automatically re-bind to their data source
whenever the data source changes (for example after an update). However, if
the GridView is bound to a different data source than the FormView, so when
the Update operation is invoked, only the FormView receives a change event
from its data source. To force the GridView to also re-bind when the
FormView performs an update, you can call DataBind() explicitly on GridView
in the FormView ItemUpdated event.

Hope this helps. If anything is unclear, please feel free to post here.

Thanks Walter,

I do have separate DataSources and the DatBind on the ItemUpdated event
worked.

However, I have a question, you mentioned using the same DataSource for
both Master and Detail but I don't undestand how to do this. Currently I
have two DataSources and for the details datasource I define a
SelectParameter that is bound to the Master GridView SelectedValue event.



<SelectParameters>
<asp:ControlParameter ControlID="GridViewEvents" Name="eventID"
PropertyName="SelectedValue" Type="Int64" />
</SelectParameters>


How can I achieve the master/detail with the same DataSource?

Thanks,

Hello,

I think Walter means if they controls are bound to same underlying
datasourece (database, maybe), so that the data on the page can be
refreshed correctly. If it is ASP.NET ObjectDataSource component, I think
we need to use two different ObjectDataSource components on Master and
Detail pages, your solution is just on the way.

If there is any further question, please feel free to let us know.

Thanks,
