AutoEventWireup Problem

I'm using the following code to verify weather the checkbox in the template
column of the datalist1 is checked
'
Sub Button1_Click(s ender As Object, e As EventArgs)
cart.text="" Dim i As Integer For i = 0 To productlist.Con trols.Count - 1
Dim item As DataListItem = productlist.Con trols(i) If item.ItemType =
ListItemType.It em Or item.ItemType = ListItemType.Al ternatingItem Then
Dim cb As System.Web.UI.W ebControls.Chec kBox =
item.FindContro l("CheckBox1" ) 'Checkbox control in the datalist
Dim tb As System.Web.UI.W ebControls.Text Box = item.FindContro l("TB1")' Text
box control
Dim cod As System.Web.UI.W ebControls.Labe l = item.FindContro l("LB1")' Label
control in datalist
If cb.Checked = "True" Then cart.visible ="true"
cart.Text += "["+ cod.Text + "X " + tb.Text+ "]"
End If
end if
next
End Sub

' This is my datalist design
<asp:DataList id="productlist " runat="server" Height="42px"
RepeatColumns=" 3" RepeatDirection ="Horizontal " HorizontalAlign ="Center"
width="100%" DataKeyField="C ode" GridLines="Both "
ItemStyle-HorizontalAlign ="Center">
<ItemStyle horizontalalign ="Center"></ItemStyle>
<ItemTemplate >
<asp:HyperLin k id="HyperLink1 " Target="_blank"
Runat="server" Text="Click to Enlarge"
ImageUrl='<%#st ring.format("im ages/th_{0}.jpg",con tainer.dataitem ("Code"))%>'
NavigateUrl='<% #string.format( "maximage.aspx? SI={0}",contain er.dataitem("Co de"))%>'></asp:HyperLink>
<br />
<asp:Label id="LB1" text='<%#contai ner.dataitem("C ode")%>'
runat="server"> </asp:Label>
<br />
<asp:CheckBox id="CheckBox1" Runat="server"
Checked="True"> </asp:CheckBox>
Quantity:<asp:T extBox id="TB1" Runat="server"
Width="40px"></asp:TextBox>
<br />
</ItemTemplate>
</asp:DataList>

When I set AutoEvent Wireup ="False" then the page_load sub does not run
when i set it to "True" then the Button1_click sub does not run.
After the page load event occurs(autoeven twireup="false" ) i set
autoeventwireup ="true" and refresh the page then every thing seems to work
fine. What do I do?
Thanx

It's probably a bug. Don't use AutoEventWireup , bind the event handler
by yourself.

I have a user control that builds a treeview dynamically in the Page_Load event. Also, I have the AutoEventWireup property set to true (i.e., <%@ Control AutoEventWireup="true" %>). Then, when I 'run' the application, I get two treeviews instead of one. I'm thinking this is because of the AutoEventWireup property being set to true. 1. Am I correct? If so, if the AutoEventWireup property is true, why does it create two treeview in my user...

Hi: This morning I found something wrong in my asp.net application: some pages and user controls didn't work well. it seems their Page_load method didnot work. For example if add a statement in the first line in the method "Page_load": Response.write("hello"); . But nothing showed up when running the page. But when I changed the AutoEventWireup to be "true" from "false", they work well again.

Ok.. I am totally stumped on this one. My site was workign great for awhile until I needed to have a Page_load event added to it. I added it and saw that it wasn't working. After ripping apart my code, I found out my problem was the autoeventwireup="false" was causing my problem. So I then changed it to true and was happy to see my page_load was working. Further testing of my site lead me to my next and current issue. I have a...

Hi all, Looks like autoEventWireup defaults to true in 2.0. Kinda silly if you ask me, since the MS site says there's a performance penalty, and I can't imagine it's something used very often! Anyway, anyone know where to change this setting? I've set the "default" in web.config to false, but new pages still have it coded into the page directive as true, which overrides. I don't want to have to do a search/replace before I publish the...

OK, guys, usually I answer questions instead of asking them, but this thing has me scratching my head. Why is the default for AutoEventWireup different for C# and VB.NET ? In VS 2005, if I create a new VB website using code-behind, the following Page directive is inserted : <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

hi, i'm new to .net 2.0, and am just starting to get to grips with the gridview. my page has autoEventWireUp set to true, which i gather is supposed to figure out which handlers to invoke when appropriate based on your method names . the GridView has OnRowCommand="GridView1_RowCommand" in the aspx. my problem is that the RowCommand event is firing twice (95% of the time) on the page. the other 5% it only fires once. there's no

I read that autoeventwireup="false" doesn't cause Page_Load to fire automatically and trying it out with a simple page this can be confirmed easily. However, I have a page with autoeventwireup="false" (that has a masterpage with autoeventwireup="false" as well) and Page_Load DOES fire in the page. How can this be ? Other pages using the same Master page does NOT fire Page_Load, unless I wire up the event manually. I'm totally confused....

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
