there are some serious problems in using FormView for example when we want to access server controls such as DropDownList, that located in FormView in the following Event
<br />
Protected Sub FormView1_ModeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.ModeChanged<br />
Dim ddl As DropDownList = CType(FormView1.Row.FindControl("DropDownList2"), DropDownList)<br />
DropDownList1.Text = ddl.SelectedItem.Text End Sub<br />
an exeption ocured for bolded line
Object reference not set to an instance of an object.
noticed that DropDownList2 located in FormView EditItemTemplate and DropDownList1 located out side of FormView Control

You should never use 'as' without checking if the resultant variable is nothing first. That's what as is for.
I've never used a FormView, but from the questions I read here, it sounds like they suck.
If you get the exception in your data layer, then your connection string must be broken.

Hi,
I working with Visual Studio 2005 and Ajax Control Toolkit ver. 1.0.20229.
I'm trying to set an accordion in my web application.
The problem is that when I put on design mode, instead of the accordion, I see an error message:
"Error creating control - Accordion1
Type 'AjaxControlToolkit.Accordion' does not have a public property named 'AccordionExtender'."
The code of course can not be compiled.
My source is that:
<br />
<cc1:Accordion ID="Accordion1" runat="server" Height="50px" Width="300px"><br />
<cc1:AccordionExtender ID="Accordion1_AccordionExtender" runat="server" Enabled="True"<br />
TargetControlID="Accordion1"><br />
<Panes><br />
<cc1:AccordionPane runat="server"></cc1:AccordionPane><br />
</Panes><br />
</cc1:AccordionExtender><br />
</cc1:Accordion><br />
Is there any one with an idea to solve this problem?
Thanks

I think this was an issue with earlier version of Toolkit.
Try downloading the latest release and see what happens.
There is also a nice sample which gets installed in the Toolkit directory.
Try running this sample and see if Accordion control works properly here or not.

I'm having the same problem with VS2005Std.
I'm trying to dynamically generate accordion panels with codebehind, but when I change any property in the design view, the source editor automatically inserts an AccordionExtender block within the Accordion block, causing the error you described.
Before:
<cc1:Accordion ID="acc1" runat="server" Width="300px" FadeTransitions="true">
</cc1:Accordion>
After:
<cc1:Accordion ID="acc1" runat="server" Width="300px" FadeTransitions="true" ContentCssClass="content" HeaderCssClass="header">
<cc1:AccordionExtender ID="acc1_AccordionExtender" runat="server" ContentCssClass="content"
Enabled="True" FadeTransitions="True" HeaderCssClass="header" TargetControlID="acc1">
</cc1:AccordionExtender>
</cc1:Accordion>
What is the reason for this and how can I work around it?

Why do people always insist on calling 'ToString' on strings ?
Have you stepped through to confirm there are more records going into the data source ?
You're binding to a label, is this how a formview words ? I'd expect a gridview or other data bound control.

That's true. Why did you ask in the wrong forum ?
You need to write a stored proc that deletes the related records. It never happens by itself.

What about foreign key constraints with on delete cascade specified?

Are there any caveats around using HashPasswordForStoringInConfigFile? Besides its daft name, I mean, why so narrow down a perfectly reusable method? I'm storing my passwords in a database, and now I have to write a damn comment telling people, "No, it isn't actually being hashed for the config file!"
|
|
|
|

I didn't know there were settings for this, but I'd never use them, if I want something, I'll use the built in hashing algorithms, but I wouldn't use a built in method that defines how they are used.

Yes, I posted my question before really looking at that method, and it's somewhat less than confidence inspiring. I'm now using MD with salt, where that method doesn't use salt.

OK - I don't know the first thing about making an MSI in VS, I use advanced installer. If it's in your project, then there must be another step to tell it to put it in the msi.

I think it needs to be all lower case. Why not just add OnClientClick to the button in the aspx ?

hello everybody;
what does it mean ? :
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
