Loop through every control

Hello,

I have a panel which contains various textboxes and dropdownlists.

I want to loop through each control inside the panel and detected if it
is a DropDownList or a TextBox so I can access its SelectedValue or
Text.

How can I do this?

Thanks,

Miguel

Click to expand...

foreach ( Control child in yourPanel.Controls )
{
if ( child is DropDownList )
{
( (DropDownList) child ).SelectedValue = "...";
}
if ( child is TextBox )
{
( (TextBox) child ).Text = "...";
}
}

This is good only if the controls are directly in the panel. Otherwise a
recursion is needed.

Yes, but the OP said "I have a panel which contains various textboxes
and dropdownlists."
