Simple steps to generate a static header in list view on asp.net

I'm struggling to keep my header fixed while scrolling and can't seem to figure it out.

Below is my ListView Code:

<asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="FormSectionSubSectionItemRelID" OnSelectedIndexChanged="ListView1_SelectedIndexChanged">

And here is the CSS code for my sites.css table:

table {
border-collapse: collapse;
border-spacing: 0;
margin-top: 0.75em;
border: 0 none;
}

th {
font-size: 1.2em;
text-align: left;
border: none 0px;
padding-left: 0;
}

th a {
display: block;
position: relative;

}

th a:link, th a:visited, th a:active, th a:hover {
color: #333;
font-weight: 600;
text-decoration: none;
padding: 0;
}

th a:hover {
color: #000;
}

th.asc a, th.desc a {
margin-right: .75em;
}

th.asc a:after, th.desc a:after {
display: block;
position: absolute;
right: 0em;
top: 0;
font-size: 0.75em;
}

th.asc a:after {
content: '▲';
}

th.desc a:after {
content: '▼';
}

td {
padding: 0.25em 2em 0.25em 0em;
border: 0 none;
}

tr.pager td {
padding: 0 0.25em 0 0;
}

If there's a property I could change or a modification in my css code that would help with fixing the header while scrolling, please let me know.

Answer №1

In order to assist you with resolving the issue, it would be beneficial if you could provide a demo of your code that includes both server-side and client-side components.

Upon reviewing your code, it appears that you are attempting to fix an element at the top of the page while scrolling. To achieve this effect, you will need to change the positioning of the element from absolute to fixed in your CSS.

th.asc a:after, th.desc a:after {
  display: block;
  position: fixed; //fixed will not scroll with the page, where absolute will.
  right: 0em;
  top: 0;
  font-size: 0.75em;
}

Utilizing advice from Scrollbar on bootstrap table and making adjustments to the LayoutTemplate, it is possible to achieve the desired outcome. It was necessary to modify some of the bootstrap CSS in order to ensure functionality.

<LayoutTemplate>
    <div>
        <table border="1" 
            style="width:96.9%; max-width:100%; background-color:#FFFFFF; border-collapse:collapse; border-color:#999999; border-style:none; border-width:1px; font-family:Verdana, Arial, Helvetica, sans-serif;">
            <thead>
                <tr>
                    <th style="width:8%; background-color: #E0FFFF; color: #333333;" >Car Number</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >License Number</th>
                    <th style="width:9%; background-color: #E0FFFF; color: #333333;" >Make</th>
                    <th style="width:8%; background-color: #E0FFFF; color: #333333;" >Model</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >Current Miles</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >Oil Change Date</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >Oil Change Miles</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >Tire Rotation Miles</th>
                    <th style="width:7%; background-color: #E0FFFF; color: #333333;" >Last Wash Date</th>
                    <th style="width:6%; background-color: #E0FFFF; color: #333333; text-align:center;" >Location</th>
                    <th style="width:4%; background-color: #E0FFFF; color: #333333; text-align:center;" >Active</th>
                    <th style="width:5%; background-color: #E0FFFF; color: #333333; text-align:center;" >New Oil Change</th>
                    <th style="width:12%; background-color: #E0FFFF; color: #333333;" >Oil Type</th>
                    <th style="width:auto; border-right:none; border-top:none;"></th>
                </tr>
            </thead>
        </table>
    </div>

     <div style="width:100%; overflow:auto; max-height:450px;">
        <table border="1" 
            style="width:98%; max-width:100%; background-color:#FFFFFF; border-collapse:collapse; border-color:#999999; border-style:none; border-width:1px; font-family: Verdana, Arial, Helvetica, sans-serif;">
            <tr runat="server" id="itemPlaceholder"></tr>
        </table>  
    </div>             

</LayoutTemplate>
