我正在使用 Telerik 网格，因为我必须在 javascript 中找到过滤控件及其值。请帮我。这是aspx的示例代码

    AllowPaging="false" AllowSorting="True" AutoGenerateColumns="False" Width="815px"
    PageSize="5" Height="430px" AllowFilteringByColumn="true" OnItemDataBound="grdQtmItemDetails_ItemDataBound"
    OnNeedDataSource="grdQtmItemDetails_NeedDataSource">
        <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>
        <MasterTableView GridLines="None" Width="250%">
             <Columns>

           <Selecting AllowRowSelect="false" />
       </ClientSettings>
       <FilterMenu EnableImageSprites="False">
       </FilterMenu>
 </telerik:RadGrid>

现在我该如何编写javascript函数

function test(sender,args)
{
//please write some code here to find filter items;
}

写一些东西来找到我的过滤器项目。提前致谢。

请尝试下面的代码片段。

ASPX：

<asp:HiddenField ID="hidden1" runat="server" />

C＃

protected void grdQtmItemDetails_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridFilteringItem)
    {
        GridFilteringItem item = (GridFilteringItem)e.Item;
        TextBox txtslno = (TextBox)item.FindControl("txtslno");
        hidden1.Value = txtslno.ClientID.ToString();
    }
}

JS

function test(sender, args) {
            var hidden = document.getElementById("hidden1").value;
            var txtslno = document.getElementById(hidden);
            if (txtslno != null) {
                // Access Your TextBox here
            }
 }

注意：如果您得到隐藏变量的值为空，请尝试使用下面的代码片段。

 var hidden = $find("<%= hidden1.ClientID %>").val();
 var hidden = $('#<%= hidden1.ClientID %>').val();
