WebGrid two-way binding issue

Hello Herman,

Yes, it is a client side. But WebGrid does Flypostback also which will request to save changes in server side. If you want completely FullPostBack, the similar scenario would be BulkUpdate which refer into what you found earlier.

Hello Handy,

Thanks for your reply. I've looked into the SmartBatchUpdate scenario, it's got almost everything I need, except for one thing. It's still updating at clientside by an AJAX call. I'd like to perform a complete page postback (because the grid lives inside a larger form and in the near future multiple grids will be added to the form). Will this also be possible with a SmartBatchUpdate?

In the meantime I found this example on the support site: http://support.intersoftpt.com/KBArticle.aspx?aid=137. Ran into some other problems with this... maybe out of the scope of this topic, so posted it in a new question http://www.intersoftpt.com/Community/WebGrid/WebGrid-BulkUpdate-with-IList-DataSource-doesnt-show-changes-on-postback/.

Thanks in advance for replies.

Regards,

Herman

Hello Herman,

It seems your scenario is more suitable in SmartBachUpdateScenario. In SmartBacthUpdate scenario, you can add,edit and delete. The modification would not be saved until you AcceptPendingChanges. Attachment is my simple sample. I created a form if user wants to add a new row into WebGrid.
The data will be saved/processed into database if user Accept the pending changes.
Please let me know your response.

Handy

WebGrid two-way binding issue

Today I've been experimenting with the WebGrid to obtain the following:

WebGrid as part of a form
Databound grid, two-way
Edit and InsertNew not enabled, insert by custom javascript
Delete enabled
When form gets posted, I'd like the data either to bound back to the datasource or programmatically be retrieved (last option preferred probably)

Currently I don't know how to achieve this by using the WebGrid. Should I use client/server binding and how about the auto-postbacks the grid seems to perform? Can I switch that off someway?

Thanks in advance.

edit: Maybe to give a better example, I'd like the grid to behave just like any other form control... load the control with or without data, modify it's value at runtime (but without interaction to the server) and process the data on postback.
