Opening pages in new tab of the browser is something you can not control...It depends on the browser and the end user preferences...
Actually Response.Redirect not even support target information...
You may use Response.Write to create a client side JavaScript code to open the link with a specific target, something like this:

C#

Response.Write("<script>window.open('Add_Items.aspx?TestID=1234','_blank');</script>");

Of course this code too, can't ensure opening in new tab only in new window...

int ID = Convert.ToInt32(e.CommandArgument.ToString());
Response.Write("<script>window.open('Add_Items.aspx?TestID="+ID ','_blank');</script>");

Passing the Id throug commandArgument, i wrote somthing wrong in above code?.
if possible how to set the page size like popup

You have some errors (missing quote and + signs):
Response.Write("<script>window.open('Add_Items.aspx?TestID=" + ID + "','_blank');</script>");

You can pass every property a normal window.open can get - including size...

I hope you are understand that this code can not! ensure new tab, only new window...It is extremely important you understand that as tabbed-browsing is relatively new we have no support for it...

my problem is solved now, but in future reference which one is more recommended. and if possible please share the "window.open can get - including size". details.

Kornfeld Eliyahu Peter 23-Feb-15 6:03am

There is no 'more recommended' - it depends on the project and the needs...
See this link for parameters for window.open - http://www.w3schools.com/jsref/met_win_open.asp, it has all you need for setting the size...

Us this:

C#

string url = "Add_Items.aspx?TestID="  + ID;
 string fullURL = "window.open('" + url + "', '_blank' );";
               ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", fullURL, true);

Wrong! It is only a new window...There is nothing in this code about tabs...It opens in a new tab only because the current configuration of the browser. On different machine with different browser of different user it will not...
