The selected item does not display in textbox of GenericDropDown

[Marie CG]

The selected item (Name) does not display in textbox of GenericDropDown.  The initial value appeared in the textbox but when I make different item in the popup panel, the new item does not show up.  I do not have images in my selection list but I don't think that would make it not working.  Help!

In Controller, I have the following:

            ViewBag.selectedBeforeEvents = db.Ratings.Where(e => e.Type == 1 && e.Scale == threat.LOIBeforeEvent).Single().Name;

            ViewBag.LOIBeforeEvents = db.Ratings.Where(e => e.Type == 1).ToList();

In View, I have the following:

 @{List<gThiraMetrix.Models.Rating> LOIBeforeEventList = ViewBag.LOIBeforeEvents;

       string selectedBeforeEvent = ViewBag.selectedBeforeEvents;

       Html.Syncfusion().GenericDropDown("LOIBeforeEventPopup")

                .DataSource(LOIBeforeEventList)

                .Text(selectedBeforeEvent)

                .BindTo(bind=>

               bind.Text("Name")

                        .Id("RatingID")).Render();}

Hi Marie,

 

Thanks for contacting Syncfusion forums.

 

Your requirement of updating the text of selected item in GenericDropdown textbox can be achieved using the “setText()” client side method. Please refer the below code snippet,

 

<code>

@{Html.Syncfusion().GenericDropDown("myGenericDropDown").ClientSideOnClick("ClientSideOnClick").Render();}                    // This event will be triggered on item select

 

[Script]

 

function ClientSideOnClick(sender, args) {

        var text = "";

        if (args._target.nodeName.toLowerCase() == "img")

            text = $(args._target.parentNode).text().trim();

        else

            text = args._text;

        sender.setText(text);                                                                                                  // This method will set the text in textbox

    }

 

</code>

 

We have also prepared a simple sample with GenericDropdown with databinding as per your code snippet and it can be downloaded from the below link.

 

Kindly have a look at the sample and let us know if your requirement is met.
