问题描述
嗨
我需要将所有值从DataGrid导出到Excel。下面是我的代码
Hi
I need to export all the values from DataGrid to Excel. Below is my code
Protected Sub btnExportExcel_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnExportExcel.Click
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=222222222.xls")
Response.Charset = String.Empty
Response.ContentType = "application/vnd.xls"
Dim StringWriter As New System.IO.StringWriter()
Dim HtmlTextWriter As New HtmlTextWriter(StringWriter)
dglist.ShowHeader = False
dglist.RenderControl(HtmlTextWriter)
Response.Write(StringWriter.ToString())
Response.[End]()
End Sub
我收到错误,因为控件''MainContent_dglist_ctl00_0''类型'' DataGridLinkButton''必须放在一个带有runat = server的表单标签内
尝试排序为false而其他人仍然得到同样的错误。
我们非常感谢您的帮助。
I am getting error as Control ''MainContent_dglist_ctl00_0'' of type ''DataGridLinkButton'' must be placed inside a form tag with runat=server"
tried sorting to false and others still I am getting same error.
Your help will be much appreciated.
推荐答案
使用以下代码。只需使用您的gridview即可完成。(: doh:将此代码转换为VB)
Use the below code.Just use your gridview and you are done.(:doh: Convert this code to VB)
protected void btnExcel_Click(object sender,EventArgs e)
{
GenerateExcel(Your GridView);//Pass your gridview to function
}
public override void VerifyRenderingInServerForm(Control control)
{
// Verifies that the control is rendered
}
public static void GenerateExcel(GridView gv)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment; filename=Leave_Report.xls");
HttpContext.Current.Response.ContentType = "application/ms-excel";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// Create a table to contain the grid
Table table = new Table();
// include the gridline settings
table.GridLines = gv.GridLines;
// add the header row to the table
if (gv.HeaderRow != null)
{
PrepareControlForExport(gv.HeaderRow);
table.Rows.Add(gv.HeaderRow);
}
//Make Header Coloruful
for (int j = 0; j < gv.Columns.Count; j++)
{
//Apply style to Individual Cells
gv.HeaderRow.Cells[j].Style.Add("background-color", "#4DB4EE");
}
// add each of the data rows to the table
foreach (GridViewRow row in gv.Rows)
{
PrepareControlForExport(row);
table.Rows.Add(row);
}
// add the footer row to the table
if (gv.FooterRow != null)
{
PrepareControlForExport(gv.FooterRow);
table.Rows.Add(gv.FooterRow);
}
// render the table into the htmlwriter
table.RenderControl(htw);
// render the htmlwriter into the response
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
}
}
private static void PrepareControlForExport(Control control)
{
for (int i = 0; i < control.Controls.Count; i++)
{
Control current = control.Controls[i];
if (current is LinkButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
}
else if (current is ImageButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
}
else if (current is HyperLink)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
}
else if (current is DropDownList)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
}
else if (current is CheckBox)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
}
if (current.HasControls())
{
PrepareControlForExport(current);
}
}
}
