This is simply process same as we enter the license key when installing any software or install windows xp or any other version of the windows.

Dynamically bind directory and subdirectory with treeview in asp.net

Description:-

         in this example we explain that how to bind directory and subdirectory or file in TreeView control or display Directory Structure in asp.net.

I had the need for a web-application that could  use TreeView control in order to present a Directory folder and file structure similar to Windows Explorer.

Here I was Defined the First Root Directory and create a TreeNode and in which we will bind the all subdirectory of the Root directory.

if you have to display All Files in Hierchy of the Directory then you have to put another Foreach Loop for the GetFiles like

 System.IO.FileInfo[] Files = directory.GetFiles();

for (int FileCount = 0; FileCount < Files.Length; FileCount++)

{

DirNode.ChildNodes.Add(new TreeNode(Files[FileCount].Name));

} 

you can also add and remove Directory dynamically in Treeview based Hierchy. we can also provide a checkboxes with each and every TreeNode so user can easily navigate to the particular directory and perfomed a operation like Add or Remove Directory under the particular root Directory.

How to Search a Place in Map using Google Map API in Asp.Net

 In this example, i will explain that  how to search place, city in a map using Google map in ASP.NET.now days When you are see  all the website or any other web contacts address are attached with map of the city with it’s proper address in the Google map. the Google has been provided a incredible map service to find the any palce, address, zipcode, state,city through the external web application. So we will implement a web application like find the address with Google map in asp.net.

Here we simply use the following link to display your location in Google map like

http://maps.google.com/maps?q=

and then we simply atteched the city and state location append to the above link like

StringBuilder queryAddress = new StringBuilder();

            queryAddress.Append("http://maps.google.com/maps?q=");

       

            if (txtCity.Text != string.Empty)

            {

                city = txtCity.Text.Replace(' ', '+');

                queryAddress.Append(city + ',' + '+');

            }

            if (txtState.Text != string.Empty)

            {

                state = txtState.Text.Replace(' ', '+');

                queryAddress.Append(state + ',' + '+');

            }

            if (txtZipCode.Text != string.Empty)

            {

                zip = txtZipCode.Text.ToString();

                queryAddress.Append(zip);

            }

            url = queryAddress.ToString();

            Response.Redirect(url, false);

And finally we will redirect the page to the url that we are created.

Using AJAX to Perform Asynchronous Deletes in MVC 4

Description:-

            In this example we explain that how to perform Asynchronous delete operation using Ajax in MVC4.

With the AJAX approach, the user clicks a “delete” link and is then presented with a JavaScript confirmation.  If the user confirms, an asynchronous call is sent to a controller action to handle the delete.  When the controller action completes, a callback is made to a JavaScript function which updates the UI by removing the deleted row from the HTML table.  It sounds pretty fancy but MVC makes it quite simple.  I should be clear, what I’m doing here isn’t clever and certainly is not unique.  I originally got the idea for this off some other blog a few years back.  I’d love to give that person credit but I’ve long since lost the link.  Mostly I’m just posting this here as a reference for myself since it seems my need to do this sort of thing comes up infrequently enough that whenever I do need to do it, I’ve since forgotten how.

The first thing we need to do is reference the jquery.unobtrusive-ajax.js and the jQuery core scripts in our view, or their minified cousins.  This is required for the AJAX link we’ll setup next.

In the project I created for this post, I’m using the MVCContrib grid, just for ease of use when it comes to laying out a model in a table.  I’m also using Twitter Bootstrap, mostly because it’s my most recent obsession and I really like how easy it is to use it to style a web app.  Bootstrap is doing nothing more than styling the table, it’s not performing any functional role in this example.  The code for the view ends up looking like this:

Check File Size before Upload or Get Image Size before Upload using jQuery

Description:-

            In previous example we already explain that how to restrict the size of file when uploaded by user through fileupload control Restrict size of file upload in asp.net.but now in this example we explain that how to get the size of file or image size before uploading to the server using jquery in asp.net. 

File uploading functionality is generally used by the every developers to  uploading file on the server.but knowing file size before uploading is a good thing because  we can restrict the end user to upload large size files on the server since we have limited space on the server.

.Net provides both facility to  check uploaded file size on server side as well client side. In this example we explain that  how to  get size of file or image size before uploading on client side using JQuery.

Here is a Jquery code to define the size limit of the uploaded file before uploading to the server.

$("#<%=upload1.ClientID %>").fileUpload({

                'uploader': 'scripts/uploader.swf',

                'cancelImg': 'cancel.png',

                'buttonText': 'Select Files',

                'script': 'Handler.ashx',

                'folder': 'images',

                'fileDesc': 'Image Files',

                'fileExt': '*.jpg;*.jpeg;*.gif;*.png',

                'multi': true,

                'auto': true,

                'sizeLimit': (100 * 1024), //200 KB

                onError: function (a, b, c, d) {

                    if (d.type === "File Size") {

                        $("#lblmsg").html('File Size Should not exceed 100 KB');

                    }

                },

                onComplete: function () {

                    $("#lblmsg").html('');

                }

            });

Look at this above code in which we predefined the size of file is 100 KB. So if user upload the larger file then 100 kb then Appropriate message will be displayed to the user.
