No button click event

Lloyd Sheen

I have a simple page with a text box and a button. The code for the button
will insert the text into SQL Server. When I click the button no code gets
invoked (not even a page load). Other pages work just fine, I have deleted
the button several times and reinserted it with no luck.

VB Code (Codebehind):

Private Sub btnAddNewCategory_Click(ByVal sender As System.Object, ByVal e

Dim products As ASPNET.StarterKit.Commerce.ProductsDB = New

Dim psCategoryId As String
psCategoryId = products.AddNewCategory(Me.txtCategoryName.Text)
Me.lblStatus.Text = "Added new Category - " + Me.txtCategoryName.Text + "
Category ID = " + psCategoryId
BindCategories()
End Sub

Sounds like your page is corrupted in some way.
Perhaps you should start again with a new page.
The only other thing I can think of is that the page might be being cached
somewhere.

You can put this code in any pages that you don't want to get cached:
Response.Expires = 0
Response.Cache.SetNoStore()
Response.AppendHeader("Pragma", "no-cache")

But if the code behind for your page is never being exectuted then neither
will this code! Obviously this code needs to be executed before it can take
effect.

Hello Lloyd,

Make sure that the btnAddNewCategory_Click event is actually hooked up.

In C#, you'd look in the OnInit() method. I'm sure VB.NET is the same.
