Why do you want to complicate your work just for a small job?

If you still wish to do it in C#, you can create transparent bitmap and save it as your desired file extension.

The following link will guide you to do so.

Well, looking at your requirement, i would not suggest to take such pain just to create a transparent image.

    }
}

                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="http://www.google.com"
                            Visible='<%# Eval("IsVisible") %>'>Link</asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>
			</Columns>
			<RowStyle BackColor="#EFF3FB" />
			<EditRowStyle BackColor="#2461BF" />

why don't you set the visibiltiy to false in the method where you bind the grid?
this is easier.

You have got to mark the property as public to access it from the markup. Change the "IsVisible" property's access specifier to "public" and your code will work. Smile | :)

HTH!

Modify the gridview code where you set the visible property like this.
Visible='<%# IsVisible %>'

hi! i've seen that you've solved your problem. but you can use also

<%=Server.HtmlEncode(IsVisible) %>

when you use IsVisible function to return a string Big Grin | :-D

(parse true to "true" and false to "false") Laugh | :laugh:

Means that you'll need SQL Server 2005, or newer. Are you running SQL Server 2000 by any chance?

Are the files you are trying to access on another server? If so are they on the same domain?

This can be quite tricky to set up. Your application won't be able to see mapped drives through IIS. Try a full UNC path to the remote location but depending on your network configuration you might need to look at impersonation.

Hey,
does any one know what might clear a session?
i have a session that is automatically cleared when i click on a hyperlink.
i couldn't trace the problem , since no event for a hyperlink.
the hyperlink is only redirecting me to another page.
I didn't clear the session in any of my codes. however it's cleared when i click on the hyperlink.

Thanks for you help.

By default session will be automatically cleared after 20 min of unusage.

In your case are you sure you are not assigning new value for the session in the page load?

sometimes it works from the first click(the session is not cleared),
but after the second click it is cleared !!!

try to put a link button instead of hyperlink and trace
the code to see where the session is being cleared
