I'm using a GridView in C#.NET 3.5 and have just converted the underlying datasource from Adapter model to an object which gets its data from LINQ to SQL - i.e. a Business object that returns a List<> for the GetData() function etc. All was well in Denmark and the Update, and conditional Select statements work as expected but I can't ge...
By default each row of a Gridview maps to each row in a datatable or dataset attached to its datasource. But what if I want to display these rows in multiple columns.

I have a gridview that is within an updatepanel for a modal popup I have on a page. The issue is that the entire page refreshes every time I click an imagebutton that is within my gridview.

Hey guys, This is my first real question of need for any of those Gridview experts out there in the .NET world.

I've got several Gridviews in my application in which I use a custom PagerTemplate. I'd like to turn this custom template into a UserControl so that I don't need to replicate the same logic in multiple pages.

I have an ASP.Net GridView control that I need to remain a fixed size whether there are 0 records or n records in the grid.

string percentage = e.Row.Cells[7].Text; I am trying to do some dynamic stuff with my GridView, so I have wired up some code to the RowDataBound event.

I'm stuck with the following problem. I'm trying to implement a basic GridView paged result set, which connects to an Oracle database. By itself, the GridView, and the paged results, work fine. The problem comes when I try to put it in page layout class that we have at work. We have ClassA, which inherits from Page, and is a corporate s...

In my grid, I have a column which calculates the total for each item (cost x quantity) and a grand total field at the bottom of the page. Currently, however, these fields are on...
When adding an EditItemTemplate of some complexity (mulitple fields in one template), and then parsing the controls from the RowUpdating event, the controls that were manually entered by the user have no values. My guess is there is something going on with when the data is bound, but I've had instances where simply adding and attribute t...

I have a GridView where one column is bound to an object property containing a nullable integer.
