ASP Repeater Control
The Repeater control is used to display a repeated list of items that are bound to the control.
The Repeater control may be bound to a database table, an XML file, or another list of items.
There will be different better ways to implement below code... I came up with this to share a sample..
Example:
<body>
<form id="frm1" method="post" runat="server">
<div id="div1">
<table align="center" width="98%" cellpadding="0" cellspacing="0" border="1">
<tr><th colspan="5" height="20">Report</th></tr>
<tr><td colspan="5"> </td></tr>
<tr>
<td colspan="5"><input type="button" id="btnExport" runat="server" value="Export Report"></td>
</tr>
<tr>
<td colspan="5">
<%
rptHistory.DataSource = Nothing
rptHistory.DataBind()
Dim dsDetails As DataSet
''Retrive Data from DB table to Dataset
If dsDetails.Tables("User").Rows.Count = 0 Then
dsDetails = Nothing
Exit Sub
Else
rptHistory.DataSource = dsDetails.Tables("User")
rptHistory.DataBind()
dsDetails = Nothing
End If
%>
</td>
</tr>
<asp:Repeater ID="rptHistory" Runat="server">
<HeaderTemplate>
<tr>
<td align="center" style="BACKGROUND-COLOR: #ffcccc"><b>Name</b></td>
<td align="center" style="BACKGROUND-COLOR: #ffcccc"><b>Age</b></td>
<td align="center" style="BACKGROUND-COLOR: #ffcccc"><b>City</b></td>
<td align="center" style="BACKGROUND-COLOR: #ffcccc"><b>School</b></td>
<td align="center" style="BACKGROUND-COLOR: #ffcccc"><b>Class</b></td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr id="trCnt" runat="server">
<td> <%# DataBinder.Eval(Container.DataItem, "Name") %></td>
<td align="center"><%# DataBinder.Eval(Container.DataItem, "Age") %></td>
<td align="center"><%# DataBinder.Eval(Container.DataItem, "City") %></td>
<td align="center"><%# DataBinder.Eval(Container.DataItem, "School") %></td>
<td> <%# DataBinder.Eval(Container.DataItem, "Class") %></td>
</tr>
</ItemTemplate>
</asp:Repeater>
<%
'Here am caching the Repeater control
Cache.Remove("Report")
Cache.Insert("Report", rptHistory)
%>
</table>
</div>
</form>
</body>
Export to Excel
Response.Clear()
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.ContentType = "application/vnd.xls"
Response.AddHeader("content-disposition", "attachment;filename=" & "Report.xls")
Dim sw As New System.IO.StringWriter
Dim htw As New HtmlTextWriter(sw)
DirectCast(Cache("Report"), Repeater).RenderControl(htw)
Dim sb1 As New System.Text.StringBuilder
sb1 = sb1.Append("<table cellSpacing='0' cellPadding='0' width='100%' align='center' border='1'>" & sw.ToString() & _
"</table>")
sw = Nothing
htw = Nothing
Response.Write(sb1.ToString())
sb1.Remove(0, sb1.Length)
Response.Flush()
Response.End()
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
