Making an entire row clickable in a gridview

Question

I have a gridview and I need to make an event fire when a row is clicked.

Is there an existing GridView event I need to bind to to make this happen?

Answer 1

There is no existing event to handle an entire row click. Your best bet is to have some javascript (maybe via ASP.NET Ajax) detect the click and fire the event yourself. Alternatively you would have to create a button or checkbox that the user selects.

Answer 2

You need to handle the "SelectedIndexChanged" event, you can then query the grid for the .SelectedRow. Alternativley use the "SelectedIndexChanging" event which sets "e.NewSelectedIndex"

Answer 3

Check out this article by Teemu, in where he explains about clicking a row in Gridview and throw the RowClicked event.

Here is a excerpt of the code:

Protected Overrides Sub RaisePostBackEvent(ByVal eventArgument As String)
            If eventArgument.StartsWith("rc") Then
                Dim index As Integer = Int32.Parse(eventArgument.Substring(2))
                Dim args As New GridViewRowClickedEventArgs(Me.Rows(index))
                OnRowClicked(args)
            Else
                MyBase.RaisePostBackEvent(eventArgument)
            End If

        End Sub

 Public Class GridViewRowClickedEventArgs
        Inherits EventArgs

        Private _row As GridViewRow
        Public Sub New(ByVal row As GridViewRow)
            _row = row
        End Sub
        Public ReadOnly Property Row() As GridViewRow
            Get
                Return _row
            End Get
        End Property
    End Class

Btw, it's in VB not C# though.

Some javascript programming will be required in order to make this happen.

Basically you are going to have to handle the click event for the row(is some browsers the row does not have a click event so you might have to handle the click event of the tds... time to invest in an ajax framework!)

You will then from javascript have to fire a postback with the row index as a parameter. See encosia(a great site for ASP.Net - ajax implementations) on how to do that. Here is a link to an article along those lines
