how to Maximize/Minimize separate sections in asp.net web application

Question

I am developing one ASP.NET Web Page in that I Want to show data, as it is in the attached link. So Please go through it. So I want the similar functionality in my We Page also.

As We can see here I have separate section for Store Details, POS Details, Registered Banks Details and so on. And If I click on +/- symbol, I should be able to maximize and minimize that particular section.

Actually I am very new to Asp.net, I have learned things by myself only so far, Nobody here to guide me. So I have no idea how to do this? What to do and what items I need to select from toolbox in Visual Studio. I have idea about PAnel Control , but with panel control I am not able to get maximize and minimize functionality here. Please help me out .

Thanks

For this you can use AJAX Toolkit controls (ToolkitScriptManager and CollapsiblePanelExtender). And for that do following steps:

(1) Learn and Download AJAX Toolkit from
http://www.asp.net/ajaxlibrary/ajaxcontroltoolkitsamplesite/ or
http://www.asp.net/ajaxlibrary/act.ashx or
http://www.stackoverflow.com/questions/15258994/how-to-add-ajaxcontroltoolkit-to-toolbox-in-vs-2012
(2) Add toolkit into your project and create one example with any one control of the toolkit
(3) Try below example as you want

<cc1:ToolkitScriptManager ID="ToolkitScriptManager2" runat="server">
    </cc1:ToolkitScriptManager>
    <asp:Panel ID="pnlCPTop" runat="server" Width="500">
        <table width="100%">
            <tr>
                <td>
                    POS DETAILS
                </td>
                <td align="right" valign="top">
                    <asp:Label ID="lblTop" runat="server">(Show Details...)</asp:Label>
                    <asp:ImageButton ID="imgTop" runat="server" AlternateText="(Show Details...)" ImageUrl="App_Themes/Default/images/expand_blue.jpg" />
                </td>
            </tr>
        </table>
    </asp:Panel>
    <asp:Panel ID="pnlTop" runat="server" Width="500">
        <table width="100%">
            <tr>
                <td>
                    TID :
                </td>
                <td>
                    abc...
                </td>
                <td>
                    Name :
                </td>
                <td>
                    xyz ...
                </td>
            </tr>
        </table>
    </asp:Panel>
    <cc1:CollapsiblePanelExtender ID="cpTop" runat="server" TargetControlID="pnlTop"
        BehaviorID="cpTop" CollapseControlID="pnlCPTop" Collapsed="False" CollapsedImage="App_Themes/Default/images/expand_blue.jpg"
        CollapsedText="(Show Details...)" ExpandControlID="pnlCPTop" ExpandedImage="App_Themes/Default/images/collapse_blue.jpg"
        ExpandedText="(Hide Details...)" ImageControlID="imgTop" SuppressPostBack="True"
        TextLabelID="lblTop">
    </cc1:CollapsiblePanelExtender>

In web config

<system.web>
 <pages>
      <controls>
        <add tagPrefix="cc1" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" />

I hope this may helps you. I suggest to first learn AJAX Toolkit and then add to tool box and then try above code.

Another way is using javascript like below:

javascript

<script type="text/javascript">
        function funHide() {
            document.getElementById('imgShow').style.display = 'block';
            document.getElementById('trPOSDETAILS').style.display = 'none';
            document.getElementById('imgHide').style.display = 'none';
        }
        function funShow() {
            document.getElementById('imgShow').style.display = 'none';
            document.getElementById('trPOSDETAILS').style.display = 'block';
            document.getElementById('imgHide').style.display = 'block';
        }
    </script>

aspx or html

<table width="500px">
        <tr>
            <td colspan='3'>
                POS DETAILS
            </td>
            <td align="right">
                <img id='imgShow' src='App_Themes/Default/images/expand_blue.jpg' alt='Show Details...' onclick="funShow()" style='display:none;'/>
                <img id='imgHide' src='App_Themes/Default/images/collapse_blue.jpg' alt='Hide Details...' onclick="funHide()" />
            </td>
        </tr>
        <tr id="trPOSDETAILS">
            <td>TID :</td>
            <td>abc...</td>
            <td>Name :</td>
            <td>xyz ...</td>
        </tr>
    </table>
