Submit button, MVC3, VB - vb.net

Question

I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?
Ideally, we want to use the selected dropdown values to determine a query. Any help is appreciated!
Thanks

Answer 1

I would include them in the view model and then pass the viewmodel back to the controller.
viewmodel
public class vm
{
//your other viewmodel data
public string? SelectedValue { get; set; }
public SelectList forDropDownUse { get; set; }
}
view
#model namespace.vm
#using (Html.BeginForm())
{
#Html.DropDownListFor(m => m.SelectedValue, forDropDownUse, " -- Select A Value -- ")
<input type="Submit" value="submit model" />
}
and then in your post action just get the selected value from the posted model object
controller (sorry, this is in c#)
[HttpPost]
public ActionResult postedAction(vm model)
{
//actions with other data in model
string selectedValue = model.SelectedValue.Value;
//work with selected value
return RedirectToAction("SomeDisplayAction");
}
Converted to vb.net from http://www.developerfusion.com/tools/convert/csharp-to-vb/
<HttpPost> _
Public Function postedAction(model As vm) As ActionResult
'actions with other data in model
Dim selectedValue As String = model.SelectedValue.Value
'work with selected value
Return RedirectToAction("SomeDisplayAction")
End Function
