我有这个 C# 事件处理程序,它假设根据列表视图的值更改文本的颜色
这是代码:
protected void YourListView_Load(object sender, EventArgs e)
{
Label theTWALabel;
int theTWAValue;
foreach (ListViewItem item in YourListView.Items)
{
theTWALabel = (Label)item.FindControl("TWALabel");
theTWAValue = Convert.ToInt32(theTWALabel.Text);
if (theTWAValue >= 0)
{
if (theTWAValue < 90)
theTWALabel.ForeColor = System.Drawing.ColorTranslator.FromHtml("YellowThis");
else
theTWALabel.ForeColor = System.Drawing.Color.Red;
}
}
}
这是列表视图行:
<asp:ListView id="YourListView" runat="server" DataSourceID="SqlDataSource3" OnLoad="YourListView_Load" EnableViewState="False">
这是我的列表视图代码:
<asp:ListView id="YourListView" runat="server" DataSourceID="SqlDataSource3" OnLoad="YourListView_Load" EnableViewState="False">
<ItemTemplate>
Plant Name:
<asp:Label id="PlantLabel" runat="server" Text='<%# Eval("Plant") %>' />
<br />
Department #:
<asp:Label id="column1Label" runat="server" Text='<%# Eval("column1") %>' />
<br />
Department Name:
<asp:Label id="GroupLabel" runat="server" Text='<%# Eval("Group") %>' />
<br />
Job Code:
<asp:Label id="Job_CodeLabel" runat="server" Text='<%# Eval("Job_Code") %>' />
<br />
TWA:
<asp:Label id="TWALabel" runat="server" Text='<%# Eval("TWA") %>' />
<br />
Job Classification:
<asp:Label id="Job_ClassificationLabel" runat="server" Text='<%# Eval("Job_Classification") %>' />
<br />
Job Function:
<asp:Label id="Job_FunctionLabel" runat="server" Text='<%# Eval("Job_Function") %>' />
<br />
Job Description:
<asp:Label id="Job_DescriptionLabel" runat="server" Text='<%# Eval("Job_Description") %>' />
<br />
<br />
</ItemTemplate>
<LayoutTemplate>
<div id="itemPlaceholderContainer" runat="server" style="font-family: Verdana, Arial, Helvetica, sans-serif; text-align:center; border:3em; border-color:black;">
<span runat="server" id="itemPlaceholder" />
</div>
</LayoutTemplate>
</asp:ListView>
问题是虽然它会正确输出我的列表视图值,但颜色都没有改变,我不知道为什么。任何帮助都会很棒
编辑:可能是因为我的布局模板控制了所有样式吗?
