[RESOLVED] [2005] Bind Checked Value of Checkbox to DataSource

[gep13]

Hello,

I am hoping you can help cause this is starting to drive me crazy!

I am in the process of converting an ASP.Net Page, coded in VB, to C#. So far everything is going fine, except for the following two lines:

<td align="right"><asp:Label ID="Label2" runat="server" Text=" [Is Approved]" Visible='<%#Eval("IsApproved")%>'/></td>

and

<td colspan="2"><asp:CheckBox ID="IsApproved" Runat="server" checked='<%# Bind("IsApproved")%>' text="Is Approved?" /></td>

When run, there lines produce the following error:

"Specified cast is not valid"

I am returning a boolean in the DataSource, so I am not sure why it is returning an error!

Is there a way to cast to a Boolean in the Bind Statement, or can you think of another way to achieve the desired result, i.e. a tick in the checkkbox when a user is approved and also a visible textbox.

(P.S. I have already posted this question in the C# forum, but no-one seemed to be able to help. SOrry for Cross Posting, can a Mod delete my other post in the C# Forum, Cheers!)

Visible='<%#Eval("IsApproved")%>'

Remove the single quote. and if it's still not working.
try to put Page.DataBind() in Page_Load().

Hello bunchhel,

I have tried both of the things that you suggested and neither of them worked?!!

Can you think of anything else that I can try?

Cheers

try this:
Visible=<%#Convert.ToBoolean(DataBinder.Eval(Container.DataItem, "IsApproved"))%>

You are the genous, cheers dude!

I have one more expression that is not working properly and I am hoping you can help!

<asp:Panel runat="server" ID="Panel3" Visible='<%# (Eval("CodeCommentCount") > 0) %>'><h5>Code Comments</h5></asp:Panel>

It is failing on the > 0 expression, how would I convert this into a useable format for C#.

Thanks again!!

Gary

Visible=<%#Convert.ToInt32(DataBinder.Eval(Container.DataItem, "CodeCommentCount")) > 0 %>

I posted the same question on the official ASP.Net Forum site and no one has been able to help me!

Cheers!!
