c# - Get checkbox.checked value programmatically from cycling through winform controls -


for winforms program, have options dialog box, , when closes, cycle throught dialog box control names (textboxes, checkboxes, etc.) , values , store them in database can read in program. can see below, can access text property control group, there's no property access checked value of textbox. need convert c, in instance, checkbox first?

conn.open(); foreach (control c in grp_invother.controls) {     string query = "insert tbl_appoptions (controlname, value) values (@control, @value)";     command = new sqlitecommand(query, conn);     command.parameters.add(new sqliteparameter("control",c.name.tostring()));     string controlval = "";     if (c.gettype() == typeof(textbox))         controlval = c.text;     else if (c.gettype() == typeof(checkbox))         controlval = c.checked; ***no such property exists!!***      command.parameters.add(new sqliteparameter("value", controlval));     command.executenonquery(); } conn.close();

if need convert c first, how go doing that?

yes, need convert it:

else if (c.gettype() == typeof(checkbox))     controlval = ((checkbox)c).checked.tostring();

and can make check simpler read:

else if (c checkbox)     controlval = ((checkbox)c).checked.tostring();
