这是布局，我有一个 FormView 控件，其中包含来自 SQL 服务器的动态数据。我正在使用 FormView 的只读模式。如何调整 PrepareFormViewForExport 方法以删除文本框并将 FormView 中的值留在后面？现在输出显示标签，但忽略了文本框中的值。
这是单击导出按钮时的 C# 代码。
protected void Bexport_Click(object sender, EventArgs e)
{
//Clear the Response object
Response.Clear();
//set Response header to the Excel filename required (.xls for excel, .doc for word)
Response.AddHeader("content-disposition", "attachment;filename=ReportOuput.xls");
Response.Charset = "";
// If you want the option to open the Excel
// file without the save option then un-comment out the line below
//Response.Cache.SetCacheability(HttpCacheability.NoCache);
//FOR EXCEL
Response.ContentType = "application/vnd.xls";
//FOR WORD
//Response.ContentType = "application/vnd.doc";
//Declare new stringwriter and html writer
StringWriter stringWrite = new System.IO.StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
//Strip out controls from FormView ?takes data too?
PrepareFormViewForExport(FormView2);
//render controls data as HTML
FormView2.RenderControl(htmlWrite);
//Clean out the Javascript postbacks etc.
string html = stringWrite.ToString();
html = Regex.Replace(html, "</?(a|A).*?>", "");
StringReader reader = new StringReader(html);
//Write xls document
Response.Write(html);
//end current Response
HttpContext.Current.Response.End();
}
这是在渲染它以供导出之前从 FormView 中删除控件的方法。
private void PrepareFormViewForExport(Control fv)
{
LinkButton lb = new LinkButton();
Literal l = new Literal();
string name = String.Empty;
TextBox TB = new TextBox();
for (int i = 0; i < fv.Controls.Count; i++)
{
if (fv.Controls[i].GetType() == typeof(LinkButton))
{
l.Text = (fv.Controls[i] as LinkButton).Text;
fv.Controls.Remove(fv.Controls[i]);
fv.Controls.AddAt(i, l);
}
else if (fv.Controls[i].GetType() == typeof(TextBox))
{
l.Text = (fv.Controls[i] as TextBox).Text;
fv.Controls.Remove(fv.Controls[i]);
fv.Controls.AddAt(i, l);
}
else if (fv.Controls[i].GetType() == typeof(DropDownList))
{
l.Text = (fv.Controls[i] as DropDownList).SelectedItem.Text;
fv.Controls.Remove(fv.Controls[i]);
fv.Controls.AddAt(i, l);
}
else if (fv.Controls[i].GetType() == typeof(CheckBox))
{
l.Text = (fv.Controls[i] as CheckBox).Checked ? "True" : "False";
fv.Controls.Remove(fv.Controls[i]);
fv.Controls.AddAt(i, l);
}
if (fv.Controls[i].HasControls())
{
PrepareFormViewForExport(fv.Controls[i]);
}
}
}
