Web Forms :: Parent-child Web Form: How To Close Dialog Box And Return Values To Parent Form?
Jan 24, 2010In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.

View 3 RepliesMVC :: Working With Parent Child Entities?
Sep 22, 2010i am working on POCO entities. i had a requirement to provide Edit feature for parent and respective Child records in single View.
Eg: Parent-Customer, Child-Order tables
when updating the parent entity by using => UpdateModel(CustomerIns);
and updating the child entity by using => TryUpdateModel(CustomerIns.Order, "Orders");
The Child Controls Names are like Orders[0].OrderID,Oders[0].OrderDate,etc
The Parent and Child Entities are updating when UpdateModel() is called but when saving Changes by calling Context.SaveChanges() i am getting exception like:
"The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted."
