Nested use of the gridview, datalist, and repeater controls

Nested use of the gridview, datalist, and repeater controls.
First, bind data to the external layer. This is easy to say.
The second step is to bind the Data Control in the inner layer. You should bind the data in the itemdatabind event of the outer control.
The procedure is as follows:
Protected void data_bind (Object sender, datalisteventargs e) // if the outer layer is datalist, the inner layer is Repeater
{
Repeater Rp = (repeater) E. Item. findcontrols ("repeater1 ");
RP. datasource = Ds;
RP. databind ();
}
Nested binding is implemented.
