I am having trouble validating the use inputs once the calculate button is clicked. Any help would be greatly appreciated. All text fields must be validated using the Validation Controls and should include a summary to show errors. I would like the error messages to appear in my lblMessage.Text but nothing is showing once Calculate is clicked. (SIDE NOTE: I also cannot get my Clear button to reset the textboxes to NULL. Help with that would be great too)

'do sth
End If
Next
End If
For Each u As Hour In currentHoursGroup
'do sth
Next
Next
End Sub
The problem is that 'DirectCast(rptItem.FindControl("approvalRadioButton"), HtmlInputRadioButton).Checked' always returns false, even it is checked.
I did hours of research, but I can't figure out what I'm doing wrong here
I found a workaround to reach what I want.
I added in each row a hiddenfield and gave it the following attribute:
Value='<%# DataBinder.Eval(Container.DataItem, "IsApproved").ToString %>'
Then I wrote some javascript to change the value (true/false) of the hiddenfield if a radiobutton was pressed.
In the code behind I check from every repeateritem the value of the hiddenfield and I got my selected rows!
in the design view i can see the repeater, but in the browser the repeater is not showing at all.
created a repeater and can not render it. When we inspect the object, it does not appear. I took the code above it , called analyze registration data and repeat after the repeater and can not see , but the repeater not. What could be wrong ? Below the code from analyze registration data :

Your repeater needs a datasource and then you need to call DataBind.
Repeater1.DataSource = rdr
Repeater1.DataBind()
I'd recommend that you wrap that in a Not IsPostBack conditional as well
if Not IsPostback
Repeater1.DataSource = rdr
Repeater1.DataBind()
GridView1.DataSource = rdr
GridView1.DataBind()
Repeater1.DataSource = rdr
Repeater1.DataBind()
I have a datalist and a binddata Sub in vb side that works on page load and I can see all my data but then when I click edit it brings up this error:-
Invalid postback or callback argument. Event validation is enabled using in configuration or <%# Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Here is My vb code:-
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
BindData()
End Sub
Protected Sub BindData()
Dim cn As SqlConnection = New SqlConnection()
Dim cmd As SqlCommand = New SqlCommand()
cn.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
cmd.Connection = cn
cmd.CommandText = "SELECT DISTINCT Users.User_ID, Users.FirstName, Users.LastName, Users.Password, Users.Email, Users.ContactNum, Users.Address, Users.County, Users.Gender, Users.Datejoined, Users.Dateleft, Users.Subscription_ID, Subscriptions.Subscription_type FROM Users INNER JOIN Subscriptions ON Users.Subscription_ID = Subscriptions.Subscription_ID WHERE (Users.Dateleft IS NULL)"
cn.Open()

I have put Page EnableEventValidation="false" but that just does nothing, i dont tell the error but nothing happens.
Please help me.
Try changing the following code:
Sub myDataList_EditCommand(sender As Object, e As DataListCommandEventArgs) Handles MyDataList.EditCommand
BindData()
MyDataList.EditItemIndex = e.Item.ItemIndex
End Sub
to this
Sub myDataList_EditCommand(sender As Object, e As DataListCommandEventArgs) Handles MyDataList.EditCommand
MyDataList.EditItemIndex = e.Item.ItemIndex
MyDataList.DataBind()
End Sub

In the 2nd step of the wizard, I have a dropdownlist that is populated from the db. when I go to the 3rd step RegisterUser.ActiveStepChanged event if fired. In there I save the data to the db. My textboxes are saving properly but my the vb code isn't pulling the selectedIndex/Value from the dropdown.
I tried populating the dropdown in Load, PreRender and neither of them helped. I also did if not Postback which didn't help either.
Any ideas?
Here is the code Sample:
Thanks.
