View 1 Repliesi have a webform, with a lot of controls (images, labels, etc), and then all you can drag to inside a panel, to organize the itens, and after the user was finished, i want to transform the content of the panel in to a image, so the administrator can check in what position the itens are.

View 1 RepliesI have a panel and a background image. to stretch this image in the panel if the height is adjusting. I have tried to google this but have trouble find a solution for this.The image has the size: (647 X 158).
The only thing that will change is the height of the panel. Now it does repeat by default. no - repeat will probably only make the image its orignal size wich is not stretching it out over the whole panel.Otherwise I am thinking of change the size of the image itself in C#. [Code]....
Using VB, VS2010, I have a large image in a panel and want to be able to pop-up panels while hovering over it. This one large image is a picture of a lot of components that I woulld like to treat individually when I hover them. I have done this before by placing a transparent button in another panel that is absoultely positioned over the larger one. I have the button transparent with a border that shows up using hover in css. Everything works fine expcept that the panel does not show itself in the right place when viewiing in the browser window. It shows fine in design view, but shifts over while browsing in the browser. I have tried making all panels absolutely positioned. Still a problem. Is there a better way to put a panel over a panel?
View 1 RepliesI am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.
