BaseDataList.DataBind Method
Binds the control and all its child controls to the data source specified by the DataSource property.
[Visual Basic] Overrides Public Sub DataBind() [C#] public override void DataBind(); [C++] public: void DataBind(); [JScript] public override function DataBind();
Remarks
Use the DataBind method to bind the data source specified by the DataSource property with the data list control. By binding the data source with a data listing control, the information in the data source is displayed in a data listing control.
The DataBind method is also commonly used to synchronize the data source and a data listing control after information in the data source is updated. This allows any changes in the data source to also be updated in a data listing control.
