Client browser freezes when clicking more than textbox

[codejason]

Hello,

I am new to asp.net and web applications, but have reasonable experience in winforms.

I have a webcontrol where I have 4 asp.net textbox controls.

When I click on these textboxes (especially when I click on them successively) my browser will freeze occasionally and become non responsive for a second -> many seconds. I do not need to change the text to get it to freeze, nor does it always after clicking a prescribed number of times (varies).

I do not believe this happens on my development machine, but only when accessing the page from a computer other than the one it is served on.

Any advice?

It might be relevant to know that these textboxes are part of a usercontrol on the page.

This usercontrol contains asp labels, and a chart from the newish Microsoft Charting package.
The chart is a column chart with about 2000 data points, and it uses the microsoft charting tool tips (implemented with image mapping), so each of the 2000 data points have an associated image map location definition and the tooltip text.

The text boxes are no where near the chart. I did not know if this problem was somehow causes by an interaction of the chart tooltip image mapping + textboxes, or if you could actually click anywhere (chart control, labels, textbox) and get the page to occasionally freeze.

Is it probable that this problem is due to the numerous image map locations defined on the page? Note, I am sure that the places I am clicking (i.e.: textboxes) are not defined in the image map but on the same user control.

Thank you

My afterthought was correct...

I removed the image map data from the ASP.NET Microsoft Chart Control.
This fixed the problem.

Besides removing the image map data, does anyone know how I could fix this? For some reason having excessive ImageMap points causes clicking outside the image area that the imagemap is associated with (textbox and labels alike) to freeze the client browser.

Thank you.

A while ago I remember insertAlias was very excited about the Google Chart API.
He posted about it in this thread: Google Charts API.

It might be worth your while to check it out :)
