Get GridView in Multiple UserControl from codebehind

Question

IpInterfaceUC UserControl:

Answer 1

While you can recursively use FindControl to find it, a much better approach is to let the UserControl IpInterfaceUC decide how to bind data to the controls within it.

You could add a public method ShowData to you UserControl and pass the data to be displayed to it. It can then assign it to gvChannelUC.

int indexInterface=0;
foreach (DataRow row in dtDevicesListByRole.Rows)
{
    var ctrIpInterfaceUC = (Test2.SetupGroup.Ipservice.IpInterfaceUC)LoadControl("IpInterfaceUC.ascx");
    ctrIpInterfaceUC.ShowData(myRows);
    ctrIpInterfaceUC.ID = "device_"+ip+"_"+port+"$"+indexInterface;
    phDevices.Controls.Add(ctrIpInterfaceUC);//PlaceHolder for add many UserControl
}
