The print button prints out four different reports depending on the value of the three textboxes.Here is the Print button code:if (Page.IsValid) { int iTextBoxFTE40 = Convert.ToInt32(TextBoxFTE40.Text); int iTextBoxHC50 = Convert.ToInt32(TextBoxHC50.Text); int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050); if (iTextBoxFTE40 > 40) { TextBoxINST_ID.Text = Session["inst_id"].ToString(); ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE40.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>"); ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true); } else if (iTextBoxHC50 > 50) { TextBoxINST_ID.Text = Session["inst_id"].ToString(); ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE50.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>"); ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true); } else if (iTextBoxFTE4050 > 90) { TextBoxINST_ID.Text = Session["inst_id"].ToString(); ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE4050.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>"); ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true); } else { TextBoxINST_ID.Text = Session["inst_id"].ToString(); ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>"); ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true); }When the Print button is clicked this error comes up:Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'.What does this mean? It happens on this line:int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050);How can I fix this? 解决方案 If you'd bothered to read Chill60's answer[^] to your previous copy of this question[^], you'd know the answer:int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050.Text); 这篇关于尝试打印不同报告时出错的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
