我如何做到这一点？我想使用客户端脚本实现这一点。请帮忙。在编辑列单元格时隐藏另一列也可以。谢谢。示例
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
this.Store1.DataSource = new object[]
{
new object[] {},
new object[] {},
new object[] {}
};
}
}
</script>

</Listeners>
</ext:TextField>
<ext:Button
runat="server"
ItemID="AddButton"

受保护的无效页面加载（对象发送方、事件参数e）
{
如果（！X.IsAjaxRequest）
{
this.Store1.DataSource=新对象[]
{
新对象[]{}，
新对象[]{}，
新对象[]{}
};
}
}
Ext.NET v2示例
顺便说一句，这里有一个TextField的RightButtons集合，您可能想用它来代替。这是一个。在我这方面，你的代码没有显示任何内容？？！好的，我已经为store和codebehind添加了代码。
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
this.Store1.DataSource = new object[]
{
new object[] {},
new object[] {},
new object[] {}
};
}
}
