View 1 RepliesI'm using a CollapsiblePanelExtender with a checkbox. I would want to make the panel expand/collapse as the checkbox is checked and unchecked. This works but the problem I'm encountering is that when page loads the panel is not expanding or collapsing accordingly to the state which is loaded from the DB. In other words setting the Collapsed property of the CollapsiblePanelExtender int the page_load to true or false does not seem to affect it.This is what I have:
<asp:CheckBox runat="server" ID="ServiceCheckBox" AutoPostBack="true" Enabled="true"
OnCheckedChanged="CheckBoxCheckedStatusChanged" />
<asp:CollapsiblePanelExtender

I am unable to access the data in the gridview's selected row. I have done this lots of times but must be forgetting something.

View 3 RepliesOn the code below, I am having a problem setting up a CPE. When I run the program it does not look like the tutorial. When it collapsis nothing can be seen and the collapased text is not visable anywhere. On the tutorial there is a bar and arrow. Is that something I have to create seperately? Also, what kind of buttons should I use to toggel the panel. I would appreciate it if someone could post code showing how this works.

I used CollapsiblePanelExtender in a web form and would like to keep its state either collapsed or expanded by user. When user navigates away from the page and then comes back a little bit later, he still see the panel collapsed or extended. codes:formA.aspx:
<asp:Panel ID="panelPetInfoExtender" runat="server" Width="100%">
<span>Pet Information</span>
<asp:Image id="img1" runat="server" ImageUrl="collapse_blue.jpg" />
</asp:Panel>
<asp:Panel ID="panelPetInfo" runat="server">MY PET</asp:Panel>
<asp:CollapsiblePanelExtender ID="CollapsiblePanelExtender1" runat="server" TargetControlID="panelPetInfo" EnableViewState="true" ExpandControlID="panelPetInfoExtender" CollapseControlID="panelPetInfoExtender" Collapsed="true"
ImageControlID="img1" ExpandedImage="collapse_blue.jpg" CollapsedImage="expand_blue.jpg" />
I use two different collapsiblepanelExtenders with similar colapsedControlID which is not a matter here. ince both of them working but with some misbehaviour, for example if the first one is open and I click wherever on it , the second one extends. also by clicking on the second one it collapses.That means that some how an event triggers and makes them collapse or extend.I have a kind of editing panel inside each extandedPanel which are used to update something on the page. the problem is that by clicking on eachtextbox or fileupload, the second panel collapses again. before any other action. So that I can not enter the textboxes. I can do that if I use tab button on keyboard. but that sucks really.

it might be because the second extender is inside the collapsible panel itself. but why it doesn't stay in extended state?

The expanded panel contains a table. This works fine in Firefox and IE. However, when the panel is expanded in Chrome, no content is shown or rendered in the expanded state.What could be going wrong here?

Iam trying to use a UserControl named CheckBoxControl as value for the ExpandControlID/CollapseControlID attributes of the CollapsiblePanelExtender. It works fine when I use a normal CheckBox instead.

I have several CollapsiblePanelExtenders in my formview (both EditTemplate and ItemTemplate). Everything works great, except that they always expand when I move from record to record. I'd like them to keep their previous state (collapsed or expanded). How can I do this with the Formview? Outside the Formview.

I have a page which consists of a CollapsiblePanelExtender. To be specific, I have placed all my controls inside a panel and specified the TargetcontrolID as this panel and this is working perfect..Now, I just included a ModalPopupExtender control in the same page and specified the PopUpControlID as this same panel. Query1: Can CollapsiblePanelExtender and ModalPopupExtender work together?
I have also specified the CSS for the panel and for ModalPopupExtender. Have attached a part of the aspx page below.

I've read in a few places that this should close a collapsible panel:
To open: cpe1.Collapsed = true; cpe1.ClientState = "true";
To close: cpe1.Collapsed = false; cpe1.ClientState = "false";
But it doesn't seem to work from me...
I am using this to display CollapsiblePanelExtender but it's not working ad I dont know why? there is no error and it workes when i set theCollapsed to True or False but not working when I run and want the user to click roCollapsed or Expand?
<asp:CollapsiblePanelExtender ID="collapsibleSkills" runat="server" Collapsed="False" TargetControlID="panelSkills" CollapseControlID="lblSkills" ExpandControlID="lblSkills" CollapsedText="[+] Skills :" ExpandedText="[-] Skills :" TextLabelID="lblSkills"
/>
I have a CollapsiblePanelExtender, and although the attribute Collapsed="true", the content panel is initially expanded.
When I click on the associated Header Panel, the Header changes (some text and an image are changed), and the content panel remains expanded. However when I click on the header again, the header changes (back to initial state) but the content panel momentarily collapses and then expands again.
Furthermore, I decided to copy Joe Steigner's demonstration word-for-word, and I get exactly the same result as before!!
