strange problem with link buttons

D

David

This is something I had never seen before.

On an aspx page, upon pressing a link button for which I have an event
handler in the code behind, the screen shows nothing but a line that says
"true" up in the right upper corner of the browser.

I have an XP and had just installed XP Service Pack II...against my better
judgment. Please help. Thanks.

Hi David,

can you post your code ?
this sometimes happen if there are some mismatched html tags.

Hi David,

Its very difficult to figure out the error with the info you have given.
Can you post the code that you have written for the button click event.

Thanks

Here's one of the event handlers. I doubt that is where the problem lies.

private void btnViewPermit_Click(object sender, System.EventArgs e)

{

if (this.permitID == 0)

{

common.showPopUpMessage("No Permit to view", this);

return;

}

Context.Items.Add(MODE, VIEW);

Context.Items.Add(PERMIT_ID, this.permitID);

Server.Transfer("permit_viewedit.aspx");

}

See my reply to Ashish M Bhonkiya.

Do you have any idea under what circimstances the page would display nothing
but "true"? What is true? Makes no sense whatsoever.

Here is my entire html page (note the pre tag which is not included on my
page, but I did it as a workaround to show my html)

Hi David,

can u debug the code and check if you can step inside the event.
if not see there is a event inside

private void InitializeComponent()

{
this.btnViewPermit.Click += new
System.EventHandler(this.btnViewPermit_Click);
}

if its there then its something related to the page you are doing the
server.transfer

Hi David,

You can check what Ashish suggested.
Because sometimes VS.NET swallows the delegate in the Initialize which
disables the button click event.
Its a bug i guess in VS.NET

Thanks
Raghavendra

I did all that. But right before being able to step in, it prints that
string "true" It happens intermittenly.
