Get SelectedValue of Control

obrienkev · November 8th, 2007, 05:34 AM

Hi,

How do I return the value of a control that a user clicked on?

How do I get the SelectedValue?? or the SelectedItem?

Only seem able to get the Text value. But I have databinded Controls and I want to get the SelectedValue.

My code so far...

Code:

BlockControl control = (Control)sender;
ControlSelected = control.Name;
PersonSelected = control.Text;

How do I do this?

Thanks again.

Does your control either inherit from a control that exposes the SelectedValue (the dropdown list for example) or does it implement its own versions of SelectedValue?

Yes I want it to inherit from a DropDownList.

Here's my code...

Code:

private void myListBox_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                Control control = (Control)sender;
                ControlSelected = control.Name;
                ItemSelected = control.Text;
            }
        }

Why doesn't the following work?

DropDown control = (DropDown)sender;
control.SelectedValue;

or even just

myListBox.SelectedValue;
