I have the following in my columns tag of my grid, however, nothing happens when I click ok in the confirm window.  The grid doesnt delete the row and the datasource doesnt either.  Is there something else needed to wire this up when using automatic CRUD and an entity datasource?

Hello Marc,

I checked your code and I can confirm you have configured your grid and the DataSource control properly so the automatic operations should work as expected. You can try binding a Gridview with the preceding DataSource and see if the automatic operations work then in order to isolate the problem further.

Additionally, could you please specify what happens when you click on the delete button, and does the insert and update operations finish sucsessfully?

For more information on how to achieve atomatic CRUD operations with EntityDataSource, you can review the below online online resources:

I attached my datasource to a GridView like you mentioned and the delete works fine there.  My data source's are all SQL DataSources now (as seen below) and I still have the same problem.

When I click the delete column I get a standard popup asking me if I want to delete.  I click ok, and the grid updates itself by removing the grid row.  However, upon reloading the page the row is back.  sqlDataSource_OnDeleting never gets fired.

Is there some other hook I have to add to wireup the grids delete command to the datasource delete command?

Hello Marc,

Try adding DataKeyNames to the MasterTableView as below and see if it makes any difference:

<MasterTableView DataKeyNames="assessmentKeyID" ....>

Additionally, you can handle the ItemDeleted event of the grid and see if any exception is thrown there.

I added the datakeyname like you suggested. My breakpoints aren't hit for RadGrid1_OnItemDeleted and sqlDataSource_OnDeleting.

I also changed the delete column to not include the confirmation stuff and that didn't help.

Still at a loss here...


However...
Setting the following makes everything work just fine.  Is there something else I have to wire up to get the confirm prompt to actually work?

AutoGenerateDeleteColumn="true"

Hello Marc,

Please excuse me for misleading you. With the GridClientDeleteColumn the items are deleted on the client only. To delete them from database, you can do as in this demo.
Otherwise, you can use GridButtonColumn with CommandName set to Delete to delete the records in the database directly.

Check it out and let me know how it goes.

The demo you linked to doesnt work all the time.  It only works if I then cause another post back on that page after doing the delete.  If I simply leave the page and come back then the row isnt deleted.

Why is the client side delete wired into window.onunload?  Do you have a better way of triggering the js function?

Hi Marc,

The postback for items is invoked on window.onunload because it is fired when either postback is initiated from other control and or the page is closed.
However, you can implement your own logic for deleting the client-side deleted items from database.

Additionally, if you want to omit additional postbacks, you bind your grid client-side as in this demo.

Best wishes,
