更改 ListView 在 itemCreated 事件中创建的行的样式

发布于 2024-09-14 09:11:36 字数 477 浏览 4 评论 0原文

当渲染数据绑定 ListView 时,我想根据结果动态设置每行的背景颜色,在我的例子中为红色、橙色和绿色。

        protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
    {
        DataRow myRow;
        DataRowView myRowView;
        myRowView = (DataRowView)e.Item.DataItem;
        myRow = myRowView.Row;

        if (myRow[2].ToString().CompareTo("") == 1)
        {
          // Colour coding here..    
        }

    }

是否可以到达每一行的TR标签来更改样式?

非常感谢, 斯特凡

When render a databound ListView I want to dynamically set the background colour of each row depending on the results, in my case Red, Orange and Green.

        protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
    {
        DataRow myRow;
        DataRowView myRowView;
        myRowView = (DataRowView)e.Item.DataItem;
        myRow = myRowView.Row;

        if (myRow[2].ToString().CompareTo("") == 1)
        {
          // Colour coding here..    
        }

    }

Is it possible to reach the TR tag for each row to change the style?

Many thanks,
Stefan

TR 标签必须具有 runat="server" 才能使用服务器端代码;但是,您可以通过检查该项目的子项控件来注入它,而无需这样做; HTML 中可能有一个 Literal 或 LiteralControl,您可以使用字符串操作来注入...

The TR tag would have to have runat="server" to use server-side code; however, you may be able to inject it in without that by examining the controls that are the child of the item; there's probably a Literal or LiteralControl with the HTML, and you can use string manipulation to inject...

在布莱恩的大力帮助下,我找到了解决问题的方法。

我有一个 ListView,我添加了一个 id 标签(trRow)和标签 runat="server",如下所示:

<AlternatingItemTemplate>
            <tr id="trRow" runat="server" style="background-color:#FFF8DC;">

在它后面的代码中看起来像这样:

        protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
    {
        DataRow myRow;
        DataRowView myRowView;
        myRowView = (DataRowView)e.Item.DataItem;
        myRow = myRowView.Row;

        System.Web.UI.HtmlControls.HtmlTableRow myTR = (System.Web.UI.HtmlControls.HtmlTableRow)e.Item.FindControl("trRow");

        if (myRow[2].ToString().CompareTo("") == 1)
        {
            myTR.Style.Value = "background-color:#FF0000;color: #000000;";
        } else
            myTR.Style.Value = "background-color:#00FF00;color: #000000;";

    }

其中的一些逻辑仍然不正确等,只是为了展示我如何解决这个问题问题是动态更改每行的背景颜色。

I worked out a solution to my problem, with some good help from Brian.

I have a ListView and I added an id tag (trRow) and tag runat="server" like this:

<AlternatingItemTemplate>
            <tr id="trRow" runat="server" style="background-color:#FFF8DC;">

In code behind it looks like this:

        protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
    {
        DataRow myRow;
        DataRowView myRowView;
        myRowView = (DataRowView)e.Item.DataItem;
        myRow = myRowView.Row;

        System.Web.UI.HtmlControls.HtmlTableRow myTR = (System.Web.UI.HtmlControls.HtmlTableRow)e.Item.FindControl("trRow");

        if (myRow[2].ToString().CompareTo("") == 1)
        {
            myTR.Style.Value = "background-color:#FF0000;color: #000000;";
        } else
            myTR.Style.Value = "background-color:#00FF00;color: #000000;";

    }

Some of the logic in there is still not correct etc, just to show how I solved the issue to dynamically change the background color of each row.
