If you didn't complete the earlier tutorials, as a starting point for this tutorial you can download the application that you would have created.You can also download the application that is created by the complete tutorial series.
NET Web Forms applications using the Entity Framework 4.0 and Visual Studio 2010.
Net 2.0 which is very easier then Data Grid Control in ASP. I will also explain what are the differences in Grid View and Datagrid Control in ASP. I want to explain how to work with template column having datagrid inside. Net 2.0 Grid View control is too good, easy and very user friendly.
The basic idea behind this article is to workout with ASP. Though I had faced lot of difficulties in this but still I can say it is far better then ASP. Grid View control gives you Edit, Update, Delete, Sorting, Selection and Paging facility built in.
But here it will not call the Row Command event of Master Grid it will directly call Row Command event of Child Grid. Now it will call Row Data Bound of Mastergrid here you will find the whether the Row State of particular Row is edit then you will find Child Grid with Edit and Delete Command in the Edit Tempalate of Template Column. When you press Edit Command of Child Grid it will Row Command of Child Grid unlike ASP.
Net1.1 's Datagrid call the Item Command of Mastergrid.
And after it will call the Row Updating event of the Child Grid.
This tutorial series builds on the Contoso University web application that is created by the Getting Started with the Entity Framework 4.0 tutorial series.For example, you can perform logging every time an entity is updated, archive data whenever an entity is deleted, or automatically check and update related data as needed when inserting a row with a foreign key value. For example, when you update a department, you might need to validate that no other departments have the same administrator because one person cannot be administrator of more than one department.In some that includes both business logic and data-access logic.So In the Template Column child grid with edit and delete option will get visible.Now, the biggest problem with this child grid is that each and every event you to write manually because grid will lost it's binding when any command is get fired. Net1.1's datagrid child grid's handler will get called when any command of childgird get fired like Edit, Delete, Sorting, Paging. Net1.1 Data grid's Inner control's event will be first handled by Grid's Item Command event irrespective of whether that control is Data Grid, Button, List Box etc.To bind the Child Grid to Child Data Source we have to use Row Data Bound event which is called every time when each row from database is bind to the Grid View's row.
