Question

Let’s say that I have 100 dropdownlists with the class “statuses”. How can I bind all webcontrols with the class “statuses” to the same datasource instead of doing it one by one?

Thanks in advance!

All controls are located in Page.Controls which you can iterate accordingly:

private void Page_Load(object sender, System.EventArgs e)
{
    LoopDropDownLists(Page.Controls);
}

private void LoopDropDownLists(ControlCollection controlCollection)
{
    foreach(Control control in controlCollection)
    {
        if(control is DropDownList)
        {
            ((DropDownList)control).DataSource = //Set datasource here!
        }

        if(control.Controls != null)
        {
            LoopDropDownLists(control.Controls);
        }
    }
}

I am however intrigued by your need for 100 DropDownLists, is this user friendly?
