How to open page in new tab using the response. redirect at asp.net

Question

I want to open a new tab or a new page by using Response.Redirect in a button click handler. I'm using a query string to pass some values. How can I open he page in a new tab?

protected void btnSave_Click(object sender, EventArgs e) {     ...//some code to insert records     Response.Redirect("NewQuote.aspx?val=" + this.txtQuotationNo.Text);//displaying gridview in other page to print what needed }

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>"); }
