To present data from several data source ASP.NET introduced controls like datagrid, datalist & repeater. Compare to datagrid repeater is connection oriented & gives faster access to data. Inner logic of repeater is similar to pointer. During data bind for custom structure repeater control is very useful. In this example I created a demo app to display a XML file data in tabular shape using ASP.NET repeater control.

Fetch Data from a XML File

In the below example I have a employees.xml file which contains name, designation, company & salary of several employees. What I want is, I want to display these data in a HTML Table using ASP.NET repeater control. To achieve this in code-behind file “Default.aspx.vb” page_load event I am creating an instance of new DataSet as employeelog. Then using ReadXml() method I am assigning the XML file data to the DataSet employeelog. Later to bind these data in repeater control I pointed the repeater control DataSource to DataSet employeelog. Finally calling emplog.DataBind() to bind XML data.

Now in Default.aspx page I have my repeater control is with data. To show these data in particular table rows & columns here I used <%#Container.DataItem(“Respective Field Name”)%> inside ItemTemplate of repeater control. To make each data rows user friendly here with ItemTemplate I used AlternatingItemTemplate with background color #e8e8e8.
