preview

I am using PrimeFaces 5.3 <p:fileUpload> to upload a PNG image and I would like to show a preview of it in <p:graphicImage> before saving in database. Here's a MCVE: <h:form enctype="multipart/form-data"> <p:fileUpload value="#{bean.uploadedFile}" mode="simple" /> <p:graphicImage value="#{bean.image}" /> <p:commandButton action="#{bean.preview}" ajax="false" value="Preview" /> </h:form> private UploadedFile uploadedFile; public UploadedFile getUploadedFile() { return uploadedFile; } public void setUploadedFile(UploadedFile uploadedFile) { this.uploadedFile = uploadedFile; } public void preview

The behavior described here appears to now be the default for ASP.NET MVC 2 (at least for Preview 1). When modelbinding a querystring like this : ?Foo=&Bar=cat The following binding occurs (assuming you're binding to a model with 'Foo' and 'Bar' string properties) ASP.NET MVC 1 model.Foo = ""; model.Bar = "cat": ASP.NET MVC 2 (preview 1 through RC) model.Foo = null; model.Bar = "cat": Wanted to give anyone who is playing with V2 a heads up since this wasn't mentioned in the ' gu-notes '. Also curious if anyone in the know can comment on whether or not this will be the final implementation or a

I need to preview an image prior to submitting a form. I work with Rails 3 and needs something that is browser compatible. Any ideas how I can achieve that? Kulgar So! :) The main idea is to use the FileReader Javascript Class, which is really handy for what you need to do. You just have to listen to the "change" event on your file input and then call a method that will use the "readAsDataURL()" method of the FileReader class. Then you just have to fill the source of a "preview img tag" with the returned result of the method... I've wrote you a simple jsFiddle that achieves what you want. You

With MVC 2's addition of the HtmlHelper EditorFor() it is not possible to create strongly typed Display and Editor templates for a given Model object and after fiddling with it I am a bit stumped as to how to pass additional Model data to the editor without losing the strong-typing of the editor control. Classic Example: Product has Category. ProductEditor has a DropDownList for Category containing the names of all Categories. The ProductEditor is strongly typed to Product and we need to pass in the SelectList of Categories as well as the Product. With a standard view we would wrap the Model

I've been using rails for past few days and wanted to know what is best way to show image previews before upload in rails & carrierwave. I came across a few options like using plupload or jquery file upload or using uploadify. If you only need image preview in a form before upload, you (as me) will see that JQuery Upload plugin is just too much complex and not so easy to run properly (I was able to see the preview, but then I couldn't upload the picture). http://saravani.wordpress.com/2012/03/14/preview-of-an-image-before-it-is-uploaded/ It's simple and fast to code. I put the code here just

I want to show preview of an image before it is uploaded. I have found a partial solution that works for ie6 and firefox, and havent yet tested it in ie7 or ie8. But i want a solution that works in safari, ie7 and ie8 as well. Here is the solution obtained by combining the ie6 and firefox solution: function preview(what) { if(jQuery.browser.msie) { document.getElementById("preview-photo").src=what.value; return; } else if(jQuery.browser.safari) { document.getElementById("preview-photo").src=what.value; return; } document.getElementById("preview-photo").src=what.files[0].getAsDataURL(); //
