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);
}
