c# - How to use new window instead of new tab display gridview data on click event in .net? -

here code:

response.write("window.open('loginfo.aspx?id=" + btn.commandargument  "','height=200,width=200,alwaysraised=yes')");  

but still didn't work new window instead of new tab.

now got shows data in gridview in new tab, need show new window.

for should do?

update:

<asp:templatefield headertext="log info">       <itemtemplate>              <asp:button runat="server" id="btnloginfo" text="log-info" commandargument='<%# eval("book_id") %>' onclick="loginfo_click"/>            </itemtemplate>           <controlstyle backcolor="#ff0066" forecolor="white" />       </asp:templatefield> 

cs:

  protected void loginfo_click(object sender, eventargs e)         {             button btn = (button)(sender);                        scriptmanager.registerstartupscript(                  this,                  gettype(),                  "open_window",                  "window.open('loginfo.aspx?id=" + btn.commandargument + "','height=200,width=200,alwaysraised=yes')",true);                    } 

you need add script> tags , _blank open in new window:

response.write("<script>window.open('webform2.aspx?id=" + btn.commandargument + "','_blank', 'height=200,width=200,alwaysraised=yes')</script>");
