Scrollable Gridview With fixheader using JQuery in Asp.net


Scrollable Gridview With fixheader using JQuery in Asp.net

Introduction:

In this article I will explain how to implement scrollable gridview with fixed header in asp.net using JQuery. 



Description: 

In Previous posts I explained lot of articles regarding Gridview. Now I will explain how to implement scrollable gridview with fixed header in asp.net. I have one gridview that contains lot of records and I used paging for gridview but the requirement is to display all the records without paging. I removed paging at that time gridview occupied lot of space because it contains more records to solve this problem we implemented scrollbar.  After scrollbar implementation if we scroll the gridview we are unable to see Gridview header.  


To implement Scrollable gridview with fixed header I tried to implement concept with css and JavaScript but there is no luck because maintaining fixed header working in IE but not in Mozilla and vice versa to solve this browser compatibility problem I used JQuery plugin to maintain fixed header for scrollable gridview and I tested it in all the browsers it’s working fine without any problem.

First design the table in database and give name UserInfomation

ColumnName
DataType
UserId
Int(set identity property=true)
UserName
varchar(50)
LastName
varchar(50)
Location
varchar(50)

After completion table creation design aspx page like this
 

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/ScrollableGridPlugin.js" type="text/javascript"></script>
<title>Scrollable Gridview with Fixed Header</title>
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#<%=gvdetails.ClientID %>').Scrollable({
        ScrollHeight: 300
    });
)
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:GridView runat="server" ID="gvdetails" DataSourceID="dsdetails" AutoGenerateColumns="false">
<RowStyle BackColor="#EFF3FB" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:BoundField DataField="UserId" HeaderText="UserId" />
<asp:BoundField DataField="UserName" HeaderText="UserName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" />
<asp:BoundField DataField="Location" HeaderText="Location" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="dsdetails" runat="server"ConnectionString="<%$ConnectionStrings:dbconnection %>"
SelectCommand="select * from UserInformation"/>
</form>
</body>
</html>
If you observe above code I added jquery-1.4.1.min.js and ScrollableGridPlugin.js script files in header section of code you need to download the attached code to get these script files by using these files we can manage the gridview header fixed postion.

Here don’t forgot to set the connection string in web.config file here I am getting database connection from web.config file for that reason you need to set the connectionstring in web.config file like this

<connectionStrings>
<add name="dbconnection" connectionString="Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB"/>
</connectionStrings>
