Sometimes we need to do fill DropDownList using JQuery & Generic Handler in ASP.NET 4.5.2. You can see this in the example below:

Design Page:
<asp:DropDownList ID=”ddlState” runat=”server” OnPreRender=”ddlState_PreRender”
CssClass=”choose_dropdown”>
<asp:ListItem Value=”0″>SELECT YOUR STATE</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID=”ddlProduct” runat=”server”
CssClass=”choose_dropdown”>
</asp:DropDownList>

Generic Handler:
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = “application/json”;
int id = Convert.ToInt32(context.Request["id"]);
string sJSON = GetProduct(id);
context.Response.Write(sJSON);
}
public string GetProduct(int id)
{
ProductController objPrductCont = new ProductController();//My Class Name
//GetProductsByStateID(id) = It will Give All Record On The Basis Of ID
List<ProductInfo> objProduct = objPrductCont.GetProductsByStateID(id);
//Converting Object into JSON
System.Web.Script.Serialization.JavaScriptSerializer oSerializer =
new System.Web.Script.Serialization.JavaScriptSerializer();
string sJSON = oSerializer.Serialize(objProduct);
return sJSON;
}

JQuery Script:
$(“select[id$=ddlState]“).change(function () {
var statVal = $(“select[id$=ddlState]“).val();
if (statVal != “SELECT YOUR STATE”) {
var id = statVal = $(“select[id$=ddlState]“).val();// You will get the value of selected item
$.post(“/CallHandler.ashx”, { id: id }, function (result) {
$(“select[id$=ddlProduct]“).empty();
$(“select[id$=ddlProduct]“).removeAttr(“disabled”);
$(“select[id$=ddlProduct]“).attr(“style”, “cursor:default”);
$(“select[id$=ddlProduct]“).append($(“<option></option>”).val(0).html(“SELECT YOUR PRODUCT”));
$(result).each(function (i) {
$(“select[id$=ddlProduct]“).append($(“<option></option>”).val(result[i].Id).html(result[i].ProductName));
});
});
}
else {
$(“select[id$=ddlProduct]“).empty();
$(“select[id$=ddlProduct]“).append($(“<option></option>”).val(0).html(“SELECT YOUR PRODUCT”));
$(“select[id$=ddlProduct]“).attr(“disabled”, “disabled”);
return false;
}
});

Have you encountered the error “Binding failure error - "Cannot start the website because administrative privileges are required to bind to the host name or port" while starting to debug your ASP.NET web application?

PROBLEM
I had one simple web app, created with the MVC5 C# template, which worked all okay until few days. Suddenly, when try to start up I got a message "Cannot start the website because administrative privileges are required to bind to the host name or port" The project was created with Visual Studio 2013 before last update version 3. also I try tried to start project in Visual Studio 2012 and that was also unsuccessful.

SOLVING
1. Close your Visual Studio solution and go to your project’s folder and find the CSPROJ file.
2. Open it using your favorite text editor and find the following lines
3.  Search for these two lines and DELETE them:

<DevelopmentServerPort>0</DevelopmentServerPort>

<IISUrl>http://localhost:57680/</IISUrl>

4. Save CSPROJ file
5. Open your solution again and start debugging. You should now be able to debug your web application.

Let me know if this solution for the issue  “Binding failure error – Cannot start the website because administrative privileges are required to bind to the hostname or port” works for you.

Sometimes, we will get requirements where we need to zip the files at runtime before sending it to the client side. For example, if our ASP.NET 4.5.2 application allows users to download multiple files at a time it will be better if we can zip it as a single file and make it available in a single download instead of downloading them individually. Doing this will give performance benefits and better user experience. Today, I wanted a simple way to create a backup of my posts, without resorting to FTP.  My solution is to create a URL that allows me to download the entire posts folder as a zip archive. To do the zipping, I used DotNetZip which is available as a nuget package and has a nice clean API.

Then in the Razor view (e.g. export.cshtml), the following code can be used to create a zip archive:
@using Ionic.Zip
@{
    Response.Clear();
    Response.BufferOutput = false; // for large files
    System.Web.HttpContext c= System.Web.HttpContext.Current;
    string archiveName= String.Format("archive-{0}.zip",
            DateTime.Now.ToString("yyyy-MMM-dd-HHmmss"));
    Response.ContentType = "application/zip";
    Response.AddHeader("content-disposition", <br>             "filename=" + archiveName);
    var postsFolder = Server.MapPath("~/posts");
    using (ZipFile zip = new ZipFile())
    {
        zip.AddDirectory(postsFolder);
        zip.AddEntry("Readme.txt",
            String.Format("Archive created on {0}", DateTime.Now);
        zip.Save(Response.OutputStream);
    }
    Response.Close();   
}
It’s very straightforward, and I have also shown adding your own custom readme.txt from a string. If you’d rather add each file manually, just provide an enumeration of files to add to zip.AddFiles.

Finally, it would probably not be a great idea to let anyone call this, so you can protect it with a simple call to IsAuthenticated:
if (User.Identity.IsAuthenticated)
