In this example, I will show how to bind data using code behind to Data List control using ASP.Net C#.
In this example I have created a list of student to supply data to DatalList but real time data will be collected from database. After taking DatalList Control we need to take ItemTemplate within ItemTemplate we need to desing the DataList using table and need to create necessary column ,within table need to label and other required control.Then we need to click double click on ItemDataBound of the DataList Control.
Output:
