Copy Code

private void WebGrid1_InitializeDataSource(object sender,
ISNet.WebUI.WebGrid.DataSourceEventArgs e)
{
    // this event will only invoked once, when the page is loaded

Remarks

WebGrid.NET provides a single databinding event handler that automatically utilizes the built-in data caching mechanism. Developers are highly recommended to use the provided event for maximum performance of data binding process.

The InitializeDataSource event is the default event of WebGrid control, you can write the implementation of it simply by double clicking on the WebGrid control at design-time. The example above shows you a simplified and centralized data binding process codes. You don't even have to call DataBind(), all you need to do is to assign the DataSource to the e.DataSource property.
