Hello,

I have a GridView which is being created at runtime. When I delete a
row the grid is only updated after i make refresh on my browser? Why?

I have the gvPosts.Databind() on my RowDeleting event.

Maybe the order and placement of my gridview properties and bind is
wrong through my gridview events.

Could someone, please, check this out? Here are the 3 events I am
using:

Protected Sub gvPosts_Init(ByVal sender As Object, ByVal e As
EventArgs) Handles gvPosts.Init

gvPosts.AutoGenerateColumns = False
gvPosts.ID = "gvPosts"

Dim tfPost As New TemplateField
tfPost.ItemTemplate = New tfPost(ListItemType.Item)
gvPosts.Columns.Add(tfPost)

End Sub ' gvPosts_Init

Private Sub gvPosts_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles gvPosts.Load

Dim mc As New MyClass
With gvPosts
.DataSource = mc.GetData
.DataKeyNames = New String() {"Id"}
.DataBind()
End With

End Sub ' gvPosts_Load

Protected Sub gvPosts_RowDeleting(ByVal sender As Object, ByVal e
As GridViewDeleteEventArgs) Handles gvPosts.RowDeleting

Dim mc As New MyClass
mc.Delete(New
Guid(gvPosts.DataKeys(e.RowIndex).Value.ToString()))
gvPosts.DataBind()

End Sub ' gvPosts_RowDeleting

Any idea what I am doing wrong?

Thanks,

Miguel
