Imagemap goes haywire in IE8 if master page used (Read 5022 times)

	Hi, I'm on .NET 3.5... I'm using the VB.NET Behaviors sample included with the installer (which uses an imagemap-type diagram). This works perfectly fine in IE8... But the moment I assign default.aspx a master page (which has a header at the top).... The imagemap goes haywire (in IE8).. I can still draw arrows and objects , but they appear in the wrong place below my mouse cursor. It's like the imagemap failed to account for the extra header at the top. This problem does not occur for Firefox + Google Chrome.... Can anyone help ? Regards Ed

	Hi Ed, We could not reproduce this - could you email the aspx and master files to support@mindfusion.eu? Are you using the standards or compatibility mode of IE8? Thanks, Stoyan

	Hi Stoyo, I think I found out what the problem was! - Once I remove this tag from my master page, then the problem happens: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Is this tag required for the diagramming control to function correctly ? Why does it become like that when it's removed? Regards Ed

	Hi Ed, This tag specifies the required html version, and if it is missing, IE8 enters quirks mode. I suppose the MS Ajax library which we use to get correct html element coordinates might be expecting some features to be available when it detects IE8, but they are not when in quirks mode. "When there is an old DOCTYPE or when there is no DOCTYPE, IE renders it like IE5 would", and nobody supports IE5 nowadays Stoyan

	Great to know stoyan, many thanks! Btw, I have another quick question on how I can enable Ajax with the diagramming control, I'll post it up as a new thread. Thanks again!

	Hi Stoyan, I would like to reopen this issue again - because by putting this tag in : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> What happens is the imagemap problem is now gone, but it gives me a new problem - it's almost impossible to get the Diagramming control to fill up the screen, ie. width=100% height = 100% (in both firefox + IE) I've sent you my "Behaviors" sample project (in vb.net 3.5) to your e-mail for you to see this problem. If I remove the <DOCTYPE> tag from default.master, then the control stretches very nicely to fit the screen horizontally and vertically (100%) ... but then it will cause the imagemap problem (for IE) It's like I can only have one or the other, but not both. Is there any way I can achieve both ? Thanks in advance Regards Edmund

	A little bit more to add to the above: It seems when I set the width or height of the .NET Diagramming control to 100% , it will do an autosize on its own... eg: if I drag a bubble to the edge of the control, it will autosize itself... Its only when I set absolute pixel values for the width and height, then the control's size will stay fixed. In short, what I want to achieve is this : 1) Get the Diagramming control to fill up the screen perfectly (at 100% width, 100% height), and stay fixed. 2) If the flowchart can't fit, the scrollbars should appear in the Diagramming control, not on the webpage. 3) To not have the imagemap problem in IE Is all 3 above possible at the same time ? Thanks regards Ed

	Hi Ed, We haven't received this project, could you email it to support@mindfusion.eu? The autosze you mentioned in the 100% size case - it's not done by the control, but perhaps browsers auto-size the DiagramView's DIV that contains the generated diagram image, so the DIV gets as big as the image. I suppose if this can't be done by pure html layout, you'll have to set the DIV's width and height from JavaScript. Stoyan
