Open new window with Response.Redirect() in Asp.net

Today I want share with you a very interesting tips using Response.Redirect(). In asp.net there are various ways to move from one page to another. Mostly used.
  1. Response.Redirect()
  2. Server.Transfer()
 But unfortunately you cant open a new window with those two methods. Which is possible with anchor link like <a href="#" target="_blank" >. When goggling I find that most of the answer is it is not possible or to make it possible you would add JavaScript method to using it. But I don't want this, at last I found two approaches. Now I want to share with these two approaches with asp.net  Response.Redirect() and  Server.Transfer().

First approach(easiest way):

Just use the OnClientClick event of the button. 
<asp:Button ID="btnHome" runat="Server" CssClass="button" Text="Go home"
OnClick="btnHome_Click" OnClientClick="aspnetForm.target ='_blank';"/>
protected void btnHome_Click(object sender, EventArgs e)
{
    Response.Redirect("Home.aspx");
}

If you want to access the form inside the Master page to Child page level

Button1.OnClientClick=string.Format("{0}.target='_blank';",((HtmlForm)Page.Master.FindControl("form1")).ClientID);

This code will find the controls collection and find your form and allow you to get access to the client id so you can be sure you have proper naming of it for the JavaScript to function correctly. Make sure you replace "form1" with whatever you have your parent form id="name" set to inside your Master’s page markup.

For multiple buttons on a single page and only want a specific button to launch into a new window.

<asp:Button ID="btnHomePage" runat="Server" CssClass="button" Text="Your home"
OnClick="btnHomePage_Click" OnClientClick="aspnetForm.target ='_self';"/>

protected void btnHomePage_Click(object sender, EventArgs e)
{
   //Do normal code for postback
}

For more details.visits

In next post I will share with you another approach to open new window using response.redirect() insha Allah.

Presentation @ Microsoft Talkz in AIUB

Yesterday I had joined a nice seminar at AIUB(American International University Bangladesh) arranged by Microsoft which is titled by "Microsoft Talkz". I amazed to see the interest of students at that seminar. Huge crowd in  the auditorium some students were waiting outside the hall for entrance but no single space is available for accommodate them.Really a new experience for me. I feel lucky to get the opportunity to participate that event.

Microsoft student partner(MSP) did a very good job to organize the whole event very nicely. There were also some expert technical guys discuss with new Microsoft technologies.

Razor new view engine in asp.net was my presentation topic. One can download it from here: Razor view engine in asp.net .
