Hi,
Generally speaking, ListView doesn't support custom styles for the rows. The best way to customize the rows is using GridPanel.
But see how can you could achieve the requirement in the context of ListView.
Example
<%@ 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)
{
Store store = this.ListView1.GetStore();
store.DataSource = new object[]
{
new object[] {"r"},
new object[] {"g"},
new object[] {"b"},
new object[] {"none"}
};
store.DataBind();
}
}
</script>

switch (color) {
case "r": s += "red;"; break;
case "g": s += "green;"; break;
case "b": s += "blue;"; break;
default: s += "yellow;"
}
return s;
}
</script>
<style type="text/css">
.my-listview .x-list-body dt em {
padding: 0;
}
</style>
</head>
<body>
<form runat="server">
<ext:ResourceManager runat="server" />
<ext:ListView ID="ListView1" runat="server" AutoHeight="true" Cls="my-listview">
<Store>
<ext:Store runat="server">
<Reader>
<ext:ArrayReader>
<Fields>
<ext:RecordField Name="test" />
</Fields>
</ext:ArrayReader>
</Reader>
</ext:Store>
</Store>
<Columns>
<ext:ListViewColumn Header="Test" DataIndex="test">
<XTemplate runat="server">
<Html>
<tpl for=".">
<div style="{[getColor(values.test)]} height: 20px;">{test}</div>
</tpl>
</Html>
</XTemplate>
</ext:ListViewColumn>
</Columns>
</ext:ListView>
</form>
</body>
</html>
