html helper in OptionLabel

[Silviya]

Hello,

 

What I am trying to achieve is add a placeholder in a dropdownlist that will display the binded model's property. When trying to use DisplayTextFor in the OptionLabel, I get "undefined" first option in the DropDownList. Is there a way to achieve this? I don't want to hardcode the OptionLabel.

 

Thanks

Hello Silviya,

I am afraid that it is not clear what exactly your are trying to accomplish. Would it be possible to share code or a runnable demo that demonstrates the issue? This will shed more light on the issue and will help us to understand the case.

Oh sure,

OptionLabel currently takes either a string or an object, correct?

I am building my form with placeholders because I don't want any labels. Now when it comes to dropdowns, I have decided that the OptionLabel will serve the purpose of a placeholder. For example .OptionLabel("---Department---");

But I also want to pull this string information from my metadata, just the way i do it with LabelFor.

 

So what I am basically trying to achieve is this:

 

.OptionLabel(@Html.DisplayTextFor(c=>c.Title));

 

This however returns undefined as an option label.

Hello Silviya,

Well, in that case the @Html.DisplayTextFor(c=>c.Title) method produce an unexpected output. Could you verify that the given method actually generates the correct string? If it does, then I will ask you to send us a repro demo that we can further investigate. It will help us to understand the implementation and find a proper solution of the issue.
