Viewsurl.action call with parmeter in javascript
I want to load an image from the database when on page load and when clicking a button.
when form is loading it is working fine, but when i click the button, i need to pass the value from the dropdown and call the controller on javascript using Url.Action.
when i click the button, getting Failed to load resource: the server responded with a status of 500 ()
controller method:
public FileContentResult MyAction(int compId)
{
byte[] img = new byte[100000];
img = _unitOfWork.Company.GetAll().Where(a => a.Id == compId).
Select(a => a.PhotoAd).FirstOrDefault();
if (img == null)
{
return null;
}
return new FileContentResult(img, "img/jpg");
}
View:
<body>
<div class="col-4" >
<div class="form-group row">
<div class="col-2">
<label asp-for="forCompList.CompId">Company</label>
</div>
