如果用这个，平台上控件不支持

<asp:DropDownList ID="seletPageNum" runat="server" AutoPostBack="true"></asp:DropDownList>

下拉框触发查询按钮点击事件，控制页长值。

<script type="text/javascript">
$("#seletPageNum").change(function(){
document.getElementById("btnQuery").click();
})

</script>

protected void dataSource_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
dgDataSource.PageSize = Convert.ToInt32(seletPageNum.SelectedValue);

if (e.ExecutingSelectCount == false)
{
e.InputParameters["tempID"] = Template.Id;
WhereSqlClauseBuilder where = new WhereSqlClauseBuilder();

List<KeyAndValue> dataItems = new List<KeyAndValue>();
if (!hfQueryStr.Value.IsNullOrEmpty())
dataItems = JSONSerializerExecute.Deserialize<List<KeyAndValue>>(hfQueryStr.Value);

foreach (var item in dataItems)
{
var parameter = Template.Config.DataQuery.SearchParameters.Find(p => p.ParameterName == item.Key);

if (parameter != null)
where.AppendItem(item.Key, TSqlBuilder.Instance.CheckUnicodeQuotationMark(item.Value), "", parameter.FormatString, true);
}

if (!txtQuery.Text.IsNullOrEmpty())
{//【普通搜索】
if (Template.Config.DataQuery.DefaultWhereClause.Contains("=") == true)
where.AppendItem(Template.Config.DataQuery.DefaultWhereClause.TrimEnd('='), txtQuery.Text);
else
where.AppendItem(Template.Config.DataQuery.DefaultWhereClause, "%" + txtQuery.Text + "%", "LIKE");
}

if (!string.IsNullOrEmpty(Template.DefaultValue))
{ //没值查询所有时间的数据
if (Template.IsDefault)
{
if (!ddlReportInstance.SelectedValue.IsNullOrEmpty())
{//【普通搜索】
if (ddlReportInstance.Items.Count > 0)
where.AppendItem(ReportTimeName, ddlReportInstance.SelectedItem.Text);
}
}
else
{
where.AppendItem(ReportTimeName, DataFormTemplateQueryDataAdapter.Instance.GetReportTimeName(Template.DefaultValue));
}
}

this.datasource.Condition = where;

}
}

protected void btnQuery_Click(object sender, EventArgs e)
{
this.dgDataSource.DataBind();

}
