DropDown text

In my MVC code I want to change the text of the dropdown based upon the values.

This is how i populate my dropdown

List<SelectListItem> list = new List<SelectListItem>();
if (policyCollections.rows.Count > 0)
{

foreach (Policy policy in policyCollections.rows)
{
item = new SelectListItem();
item.Text = policy.PolicyModule + " : " + policy.PolicyEffDate + " " + policy.PolicyExpDate;
item.Value = item.Text;
list.Add(item);
}

}

policydetailsModel.CurrentPolicy = policyCollections.rows.FirstOrDefault(x => x.PolicyNumber.Equals(policyNumber.Substring(policyNumber.Length - 7)) && x.MasterCompany.Equals(masterCompany) && x.PolicyModule.Equals(policyModule));
policydetailsModel.Modes = new SelectList(list,"Value","Text");

Definition for this action is

public ActionResult Details(string policyNumber, string masterCompany, string policyModule)

the parameters are being passed from a url and everytime I change the parameters in the URL (manually) I would like the text/value for the drop down to match the parameters that's being passed

If you can show me how we can get a specific text to show up in the dropdown based upon the text I pass then that will be great.

so this is what i want

string text = ab : 12-31-2015 12-31-2016

If the same exact text is present in the dropdown then show me that text when the UI loads up.

Use item.selected (boolean) to select an option. You can use a literal value ('SELECTEDVALUE') or getting from URL parameters

foreach (Policy policy in policyCollections.rows)
                {
                     item = new SelectListItem();
                    item.Text = policy.PolicyModule + " : " + policy.PolicyEffDate + "  " + policy.PolicyExpDate;
                    item.Value = item.Text;
                    // item is selected when matches a defined value
                    item.selected = (item.Value == 'SELECTEDVALUE');
                    list.Add(item);
                }

that did not work. item.selected ends up being true when the value matches but when the drop down loads it stillloads the first value and not the selected value

Here is my controller code :

PolicyDetailsModel policydetailsModel = new PolicyDetailsModel(); -- Model
SelectListItem item = null;

List<SelectListItem> list = new List<SelectListItem>();
if (policyCollections.rows.Count > 0)
{

foreach (Policy policy in policyCollections.rows)
{
item = new SelectListItem();
item.Text = policy.PolicyModule + " : " + policy.PolicyEffDate + " " + policy.PolicyExpDate;
item.Value = policy.PolicyModule + policy.MasterCompany + policy.PolicyNumber + policy.PolicySymbol;
item.Selected = (item.Value == policyModule+masterCompany+ policyNumber.Substring(policyNumber.Length-7)+policyNumber.Substring(0,policyNumber.Length-7));
list.Add(item);

}

}

policydetailsModel.CurrentPolicy = policyCollections.rows.FirstOrDefault(x => x.PolicyNumber.Equals(policyNumber.Substring(policyNumber.Length - 7)) && x.MasterCompany.Equals(masterCompany) && x.PolicyModule.Equals(policyModule));
policydetailsModel.Modes = new SelectList(list,"Value","Text");
//if (policyCollections != null)
// policyCollections.rowCount = pageSize;
// return Json(policyCollections, JsonRequestBehavior.AllowGet);

return View(policydetailsModel);

Here is my model code :

public class PolicyDetailsModel
{
public Policy CurrentPolicy { get; set; }

public SelectList Modes { get; set; }
}

here is my view code :

<dt>
@Html.DisplayNameFor(model => model.CurrentPolicy.PolicyModule)
</dt>

<dd style="font: large">
@Html.DropDownList("Modes", Model.Modes, new { onchange = "ModeChange()" })
</dd>

What do I need to do in order for this to work.
