Question

以下是将gridview转换为CSV的代码。 Gridview值不是自动生成的列，它来自数据库作为模板字段。

 try
            {
                DataTable dt1 = new DataTable();
                Response.ClearContent();
                Response.AddHeader("content-disposition", "attachment;filename=MyCsvFile.csv");
                Response.ContentType = "application/text";
                StringBuilder strBr = new StringBuilder();
                strBr.Append("\n");
                for (int j = 1; j < GridView1.Rows.Count; j++)
                {
                    strBr.AppendLine("");
                    for (int k = 0; k < GridView1.HeaderRow.Cells.Count; k++)
                    {

                        strBr.Append(GridView1.Rows[j].Cells[k].Text.Replace(",", "") + ",");

                    }
                    strBr.Append("\n");
                }
                Response.Write(strBr.ToString());
                Response.Flush();
                Response.End();
            }
            catch (Exception ex)
            {
                throw ex;
            }

这里GridView1.Rows [j] .Cells [k] .Text，这个“Text”包含空值。请帮忙......

您需要在单元格内搜索控件，因为列为TemplateField。

GridView1.Rows[j].Cells[k].FindControl('ControlId').Text

Gridview Cell文本为null转换为CSV
