We have closed this ticket because another page addresses its subject:
GridListEditor - Updating values of dependent columns immediately after changing data in columns whose ImmediatePostData attribute is set to True in an editable ListViewHello,
we added the controller supposed by Dennis (S30324) to support immediatePostData with on ListViews.
It all works fine for the focused row. Our problem is, that other rows don't refresh as long as the propertyEditor wasn't changed.
You can reproduce this behavior with the attached solution. There's a video included in the zip-file.
Best regards and thank you for your help

Hello Christian,
You can refresh an additional row using the GridView.RefreshRow method. Here is an example:
C#void ColumnEdit_EditValueChanged(object sender, EventArgs e) {
//this should'nt be necessary in filterrows (Bug 7321)
if (!gridViewCore.IsFilterRow(gridViewCore.FocusedRowHandle)) {
gridViewCore.PostEditor();
DomainObject1 focusedObj = (DomainObject1)gridViewCore.GetFocusedRow();
int relatedRowHandle = gridViewCore.FindRow(focusedObj.DomainObject1Reference);
gridViewCore.RefreshRow(relatedRowHandle);
}
}
Hi Anatol,
ok I see. Isn't there a more generic solution? The value of the property in the related row is being changed in the object bound to the related row. Unfortunately a property-change has no effect on the changed row in this case.
The controller supposed by Dennis works for every listView and our developers don't even have to know that it exists. The code you proposed has to be written for every listView with such a case (and every possible case in that listView… because of layoutCustomization it's possible to have such update problems and don't event know about them).
I don't understand the reason why the refresh isn't working automatically, maybe you could change something in your codebase?
Thank you for your answer

Hi Christian,
I'm searching for the precise answer to your question and need some more time for this. Thank you for your understanding.
I will inform you when I have any results…
I am afraid that there is no other solution for the Server Mode data source. Either change the ListView's DataAccessMode to Client, or refresh the necessary rows using the GridView,RefreshRow method. Even if a changed object can have several related objects, I believe that it is still possible to determine all these objects and refresh them.
