Hi I am trying to export a gridview to CSV except i am getting an error due to some of the columns in the gridview not being visible. Was wondering if anyone knows how to fix this or a different way to export to csv.
protected void gv_RowCreated(object sender, GridViewRowEventArgs e)
{
e.Row.Cells[0].Visible = false;
e.Row.Cells[1].Visible = false;
e.Row.Cells[3].Visible = false;
e.Row.Cells[8].Visible = false;
}
protected void export_Click(object sender, EventArgs e)
{
Response.ClearContent();
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "test.csv"));
Response.ContentType = "application/text";
gv.AllowPaging = false;
gv.DataBind();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < gv.Columns.Count; i++)
{
if (gv.Columns[i].Visible)
{
sb.Append(gv.Columns[i].HeaderText + ',');
}
}
sb.Append("\n");
for (int j = 0; j < gv.Rows.Count; j++)
{
for (int k = 0; k < gv.Columns.Count; k++)
{
sb.Append(gv.Rows[j].Cells[k].Text + ',');
}
sb.Append("\n");
}
Response.Write(sb.ToString());
Response.End();
