With the release of ASP.Net 4.5 web forms there are tons of features added in the ASP.Net and Unobtrusive validations support is one of them. We have already seen that kind of validation in ASP.Net MVC and now we are going to have that in ASP.Net web forms. In this post I am going to explain how its works and how its different from earlier versions.
In this post We are going to see How Knockout, ASP.Net Web API and ASP.Net works together smoothly. There are lots many examples of ASP.Net MVC,Web API and Knockout.js available on web working together nicely. So I thought it will be a good idea to write a blog post about how ASP.Net Web API, ASP.Net Web Forms,Knockout.js works together and how we can create simple data binding with Knockout.js.
Those are working on in web technologies like ASP.Net and ASP are already familiar with server.MapPath method. It is used to Maps a virtual or relative path to a physical path. Recently I had discussion with my friends what kind of options we have for Server.MapPath and We have discussed lots of things. So I thought it will be a good idea to write a blog post about it. I know this is very basic but sometimes we were not aware about basic things. So following are different kind of options we have with Server.MapPath.
Right now everybody is talking about HTML5 and its contains lots of new features like web sockets, canvas, new intput types with validation etc.
Sometimes ago a friend ask me how to put default focus and default button in ASP.NET. He was not knowing that there is property for that in form tag in asp.net. I thought it will be good idea to write a blog post about that.So those who are not aware of this feature can get an idea for that.
In some cases we need to have default button and default focus. For example take a example of a shopping cart registration form. Where you need to have default focus into the first textbox if you contain list of textboxes over there. Same way you can have more then one button on asp.net forms for example save and cancel so once user press enter which button should be pressed. On above both scenario this Default button and default features can come very handy.
From asp.net 2.0, The form tag has this two properties DefaultButton and DefaultFoucs where you can set the Id of control that you need as default button and same way you need to put Id of a control for default focus.
Before some months Microsoft has launched WebAPI framework for building and consuming HTTP services. This WebAPI can be called from anything like from mobile sites to JavaScript anything. I thought it will be a good idea to call a WebAPI from jQuery.
In this post I am going to explain how to consume ASP.NET WebAPI from jQuery.
New version of ASP.NET provides lots of way of binding data to the data controls like Grid View, Repeater etc. You can now bind this controls with strong type. I have earlier written a blog post about How we can use Model binding with ASP.NET 4.5 and Visual Studio 2012.
public class Employee
{
public int EmployeeId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
This class contains three properties EmployeeId,FirstName and LastName. Now I have created one method to get a generic list of employee model like following.
In this post I am going to explain about reason for InProcsessionState was not working with IIS 7.5.
<configuration> <appSettings configSource="AppSettings.config"/> <connectionStrings configSource="ConnectionStrings.config"/> </configuration>
<asp:FileUpload ID="multipleFile" runat="server" AllowMultiple="true" /> <asp:Button ID="uploadFile" runat="server" Text="Upload files" onclick="uploadFile_Click"/>
protected void uploadFile_Click(object sender, EventArgs e)
{
if (multipleFile.HasFiles)
{
foreach(HttpPostedFile uploadedFile in multipleFile.PostedFiles)
{
uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),uploadedFile.FileName));
Response.Write("File uploaded successfully");
}
}
}
