Chap. 4, Pg 121-123

tompp · August 25th, 2011, 03:24 PM

Cannot get past this error at Try It Out beginning pg. 121. Apparently 'errs' on "Result.Text" statement (VB). What's my problem

Installed MS Visual Web Dev 2010 Express, MS Visual Basic 2010 Express, MS Visual Basic 2010 Express on 64bit Windows 7. All products are current with updates.

This message in error window:
"C:\BegASPNET\Site\Demos\Containers.aspx.vb(10 ,0): error BC30456: 'Text' is not a member of 'System.Web.UI.WebControls.WizardStep'."

Thanks

Hi there,

Can you post the full code for the problematic page?

Cheers,

Imar,

Here's the code - C:/BegASPNET/Site/Demos/Containers.aspx

<asp:WizardID="Wizard1"runat="server"ActiveStepIndex="0"Width="500px">
<WizardSteps>
<asp:WizardSteprunat="server"title="About You">
<asp:LabelID="Label1"runat="server"Text="Type your name"></asp:Label>
<asp:TextBoxID="YourName"runat="server"></asp:TextBox>
</asp:WizardStep>
<asp:WizardSteprunat="server"title="Favorite Language"StepType="Finish">
<asp:DropDownListID="FavoriteLanguage"runat="server">
<asp:ListItem>C#</asp:ListItem>
<asp:ListItem>Visual Basic</asp:ListItem>
<asp:ListItem>CSS</asp:ListItem>
</asp:DropDownList>
</asp:WizardStep>
<asp:WizardSteprunat="server"StepType="Complete"Title="Result"ID="Result"Label="Result">
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>

And, here's the code - C:/BegASPNET/Site/Demos/Containers.aspx.vb

PartialClassDemos_Containers
Inherits System.Web.UI.Page
ProtectedSub CheckBox1_CheckedChanged(sender AsObject, e As System.EventArgs) Handles CheckBox1.CheckedChanged
Panel1.Visible = CheckBox1.Checked
EndSub
ProtectedSub Wizard1_FinishButtonClick(sender AsObject, e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick
Result.Text = "Your name is " & YourName.Text
Result.Text &= "<br />Your favorite language is " & FavoriteLanguage.SelectedValue
EndSub
EndClass

Here's the error from Error List:

Error 1 'Text' is not a member of 'System.Web.UI.WebControls.WizardStep'. C:\BegASPNET\Site\Demos\Containers.aspx.vb 10 5 C:\BegASPNET\Site\

Error 2 'Text' is not a member of 'System.Web.UI.WebControls.WizardStep'. C:\BegASPNET\Site\Demos\Containers.aspx.vb 11 5 C:\BegASPNET\Site\

Have entered per instructions several times, including copying from the download. Same results each time.

Love your format and instructions.

Any help is appreciated.

Hi Tom.

Did you copy and paste both the markup and the code behind from the source files? These files are correct, so maybe something else is going on.

Can you also please repost your code but then paste it into Notepad first to remove color coding, and then wrap the code in Code tags using the Code button (#) in the post's editor? Because of some stupid bug in this forum, colored code ends up really messed up... If you do repost, please post the full markup of the page and the code behind, and not just the Wizard control.

Cheers,

Imar

Ah, there we have it. Take a look at this:

Code:

 
<asp:WizardStep runat="server" StepType="Complete" Title="Result" ID="Result" Label="Result">
</asp:WizardStep>

Somehow, you merged the last Wizard step and the Result label. The code should look like this instead:

Code:

<asp:WizardStep runat="server" StepType="Complete" Title="Ready">
  <asp:Label ID="Result" runat="server" Text="Label"></asp:Label>
</asp:WizardStep>

Notice how the Label is placed inside the WizardStep definition...

If you post code in the future, please wrap it in code tags using the # button; makes the code easier to read as it preserves formatting among other things.

Hope this helps,

Imar

Imar,
Got. My bad. Thanks for the prompt assist.
