Loop through controls

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

Hope this helps:

Dim frmCtrl As Control

For each frmCtrl in oPanel.Controls

If TypeOf frmCtrl Is TextBox Then

End If

etc, etc

Next

or C#

foreach (Control ctrl in Panel.Controls)

{
if (ctrl is TextBox)
{

}

}

try this code:

for each c as control in myPanel.controls

if typeof c is TextBox then

'get text

elseif typeof c is DropDown then

'get selected value

endif

next
