Answer 1

if you are using http then use below code

Response.Write("<script>window.open ('URL','_blank');</script>");

this code cannot be used for https for https do below

javascript in page

function shwwindow(myurl) {
    window.open(myurl, '_blank');
}

in c# code behind

 string URL = ResolveClientUrl("~") + "**internal page path**";
    ScriptManager.RegisterStartupScript(this, this.GetType(), "show window", 
    "shwwindow('"+URL+"');", true);

this code cannot bybass the browser popup blocker. user must allow it to run. for ie it opens in new window or new tab up to ie version in firefox and chrome it opens new tab

enjoy it!!

You can change your design element as below : OnClientClick

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button"  OnClientClick ="document.forms[0].target = '_blank';"  />

Javascript code :

 Response.Write("<script>");
 Response.Write("window.open('NewQuote.aspx' ,'_blank')");
 Response.Write("</script>");

Answer 3

You can use ScriptManager to do the needed:

private void Redirect_New_Tab(string url_To_Open)
{    
    string modified_URL = "window.open('" + url_To_Open + "', '_blank');";
    ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", modified_URL , true);
}

I encountered this same problem today.

Response.write didn't work for me, to solve it I used instead System.Web.UI.ScriptManager.RegisterClientScriptBlock.

This is how your btnSave click event should be:

protected void btnSave_Click(object sender, EventArgs e)
{
    ...//some code to insert records
    System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "openModal", "window.open('NewQuote.aspx?val= "+ this.txtQuotationNo.Text+"' ,'_blank');", true);
}

NOTE: I'm using ScriptManager.RegisterClientScriptBlock because the button is inside an UpdatePanel, if that's not your case you should try:

protected void btnSave_Click(object sender, EventArgs e)
{
    ...//some code to insert records
    Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "openModal", "window.open('NewQuote.aspx?val= " + this.txtQuotationNo.Text + "' ,'_blank');", true);
}

Answer 5

Try this. This works sure for me...

protected void btnSave_Click(object sender, EventArgs e)
{
    ...//some code to insert records
    Response.Write("<script>window.open ('NewQuote.aspx?val=" + txtQuotationNo.Text+"','_blank');</script>");
}

Worked for me when I left the Double Quotes off of target ='_blank';
