Gridview rowupdating empty

This is where the concept of dynamically templated Grid View comes.This is a Grid View that can be bound to any table of any database of any server, providing Insert, Edit and Delete option simultaneously. Text = Field Name; private void On Data Binding(object sender, Event Args e) Hi i use datatable to bind datagridview first time code run smoothly.

One advantage using this approach is that I do have access to the underlying data source item (a Data Row here) and so I can update the value and rebind easily and immediately show the updated value(s).

Generally, a template is description of how a particular item will be rendered at run time. At design time we can define templates declaratively using inline tags in aspx source of Grid View (the following listing shows this).

Since we are going for a case where we don’t know the number of fields of a table and their description (Name, Data Type etc) in advance therefore we need to create the templates dynamically according to fields of the particular table.

It shows that we must know number of fields and their name in advance to create their templates. Listing 1 Hi Mohyudhin, Actually i tested this for my scenario and its not working when i try to add the grid control itself from code behind instead of declaring it in DOM(HTML). Thanks and regards, Ram Email Id: [email protected] created nested gridview template dynamically with the help of this article which is working perfectly with parent gridview but when i update inner gridview record,we are rebinding parent/child template again and then it will fire inner gridview 'rowcommand' event to update in this case,it will lost the the data which i have entered in controls.so,what to do???? I am posting the solution incase somebody is in search for it.

In that case the edit item template update and cancel button events are not firing. Please help me....inception is a 2010 science fiction action heist film which was written, co-produced, and directed by Christopher Nolan.

Although the Grid View Command Event Args have a Data Item member that member is unfortunately not set with the Data Row as you would maybe expect.

So rather than getting the bound item directly, I have to retrieve the grid Row's Data Item index, then use that index and retrieve the value from the original data source.

I don't know about you, but I cringe every time I need to create a Grid View based layout that needs to create a few custom link handlers off that grid.

The typical scenario might be a list where you can toggle certain options or where you can fire an operation that otherwise updates the data that's underlying the grid.

Anyway, the problem isn't that it can't be done 'manually' - but rather that there are a myriad of ways that you can hook up custom link/command processing and they are all similar but yet quite different.

None of them feels natural to me, so quite frequently - especially if I haven't written that code in a while - I spent way more time than I should rediscovering what approach I should use the hard way.

Oddly I have no idea why the data item would not be available given that this particular grid is bound to a Data Table which has persistent backing and is live on the form.
