The GridView control in ASP.NET usually loads many rows of data with a vertical scroll bar. When users scroll using vertical bar, the header of the GridView will move and disappear. This sample illustrates how to fix the header of GridView via JQuery, and this approach can also cross multiple browsers at client side.

The sample is created by our star sample writer: Arwind Gao

GridView usually has many rows with a vertical scroll bar.  When users scroll using vertical bar, the header of the GridView will  move and disappear. This sample illustrates how to fix the header of GridView via JQuery, and this approach can also cross multiple browsers at client side.



Running the Sample

Please follow these demonstration steps below.
Step 1: Open the CSASPNETFixedHeaderGridView.sln.

Step 2: Expand the CSASPNETFixedHeaderGridView web application and press Ctrl + F5 to show the Default.aspx page.

Step 3: You will see a GridView control on the page, please scroll the vertical scroll bar, the header line of the GridView not move with the scroll bar.

Step 4: Please browser this page with some other browsers, such as Chrome, FireFox, Safari, etc.


Using the Code

Step 1. Create a C# "ASP.NET Empty Web Application" in Visual Studio 2010 or Visual Web Developer 2010. Name it as "CSASPNETFixedHeaderGridView".
Step 2. Add one web form and named it as "Default.aspx".
Step 3. Create a folder named "JScript" and copy the code of sample file in your JS files. You can also download of them from these websites:
Step 4. Add a GridView on Default.aspx page, and add create a data table as GridView's data source. Here we give the code of Default.aspx.cs file.
            // Define a data table as GridView's data source.
            DataTable tab = new DataTable();
            tab.Columns.Add("a", Type.GetType("System.String"));
            tab.Columns.Add("b", Type.GetType("System.String"));
            tab.Columns.Add("c", Type.GetType("System.String"));
            tab.Columns.Add("d", Type.GetType("System.String"));
            tab.Columns.Add("e", Type.GetType("System.String"));
            tab.Columns.Add("f", Type.GetType("System.String"));
            tab.Columns.Add("g", Type.GetType("System.String"));
            tab.Columns.Add("h", Type.GetType("System.String"));
            tab.Columns.Add("i", Type.GetType("System.String"));
            tab.Columns.Add("j", Type.GetType("System.String"));
            for (int i = 0; i < 35; i++)
                DataRow dr = tab.NewRow();
                dr["a"] = string.Format("row:{0} columns:a", i.ToString().PadLeft(2,'0'));
                dr["b"] = string.Format("row:{0} columns:b", i.ToString().PadLeft(2, '0'));
                dr["c"] = string.Format("row:{0} columns:c", i.ToString().PadLeft(2, '0'));
                dr["d"] = string.Format("row:{0} columns:d", i.ToString().PadLeft(2, '0'));
                dr["e"] = string.Format("row:{0} columns:e", i.ToString().PadLeft(2, '0'));
                dr["f"] = string.Format("row:{0} columns:f", i.ToString().PadLeft(2, '0'));
                dr["g"] = string.Format("row:{0} columns:g", i.ToString().PadLeft(2, '0'));
                dr["h"] = string.Format("row:{0} columns:h", i.ToString().PadLeft(2, '0'));
                dr["i"] = string.Format("row:{0} columns:i", i.ToString().PadLeft(2, '0'));
                dr["j"] = string.Format("row:{0} columns:j", i.ToString().PadLeft(2, '0'));
           // Data bind method.
            gvwList.DataSource = tab;
Step 5. Now we need bind the specifically columns of data table to GridView's columns, The code of Default.aspx page will be like this:
                <asp:BoundField DataField="a" FooterText="titile a"
           HeaderText="titile a" />
                <asp:BoundField DataField="b" FooterText="titile b"
           HeaderText="titile b" />
                <asp:BoundField DataField="c" FooterText="titile c"
           HeaderText="titile c" />
                <asp:BoundField DataField="d" FooterText="titile d"
           HeaderText="titile d" />
                <asp:BoundField DataField="e" FooterText="titile e"
           HeaderText="titile e" />
                <asp:BoundField DataField="f" FooterText="titile f"
           HeaderText="titile f" />
                <asp:BoundField DataField="g" FooterText="titile g"
           HeaderText="titile g" />
                <asp:BoundField DataField="h" FooterText="titile h"
           HeaderText="titile h" />
                <asp:BoundField DataField="i" FooterText="titile i"
           HeaderText="titile i" />
                <asp:BoundField DataField="j" FooterText="titile j"
           HeaderText="titile j" />
Step 6. The last of step, involve the JQuery libraries and write the JQuery
       function to fixed the header of GridView control.
         The JQuery code will be like this:
             <script src="JScript/jquery-1.4.4.min.js" type="text/javascript"></script>
            <script src="JScript/ScrollableGridPlugin.js" type="text/javascript"></script>
            <script type = "text/javascript">
                $(document).ready(function () {
                    //Invoke Scrollable function.
                    $('#<%=gvwList.ClientID %>').Scrollable({
                    ScrollHeight: 600,       
Step 7. Build the application and you can debug it.
