后台代码：

protected void btnAddNewRow_Click(object sender, EventArgs e){

//首先，恢复数据源

DataTable dt = DefineDataTableSchema(hfRptColumns.Value);

foreach (RepeaterItem item in rp_List.Items)

{

DataRow newRow = dt.NewRow();

newRow["id"] = ((HiddenField)item.FindControl("hidid")).Value;

newRow["Contentzh"] = ((TextBox)item.FindControl("txtCountentzh")).Text;

newRow["Contenten"] = ((TextBox)item.FindControl("txtCountenten")).Text;

newRow["photo"] = ((TextBox)item.FindControl("txtPhoto")).Text;

newRow["orderby"] = ((TextBox)item.FindControl("txtOrder")).Text;

newRow["maxsecond"] = ((TextBox)item.FindControl("txtMaxsecond")).Text;

newRow["IsHave"] = ((Label)item.FindControl("lblsound")).Text;

newRow["soundsize"] = ((TextBox)item.FindControl("txtSoundSize")).Text;

dt.Rows.Add(newRow);

}

//添加一行

DataRow row = dt.NewRow();

row["Contentzh"] = "";

row["Contenten"] = "";

row["photo"] = "";

row["orderby"] = "0";

row["maxsecond"] = "1";

row["IsHave"] = "未上传";

row["soundsize"] = "1";

dt.Rows.Add(row);

rp_List.DataSource = dt;

rp_List.DataBind();
