设计部分在这里...

design part is here...

<asp:GridView ID="GridCall" runat="server" CssClass="Grid"

        AutoGenerateColumns="false" RowStyle-HorizontalAlign="Justify"

        ShowHeader="true" ShowFooter="false" AllowPaging="false"

        GridLines="Horizontal"

        onselectedindexchanged="GridCall_SelectedIndexChanged" AutoGenerateSelectButton="true">

<HeaderStyle BackColor="AliceBlue" BorderStyle="Double" Height="25px" HorizontalAlign="Center" VerticalAlign="Middle" />
<RowStyle BackColor="Wheat" BorderStyle="Solid" Height="20px" VerticalAlign="Middle" HorizontalAlign="Center"/>
<Columns>
<asp:TemplateField ShowHeader="true" HeaderText="Status" >
<ItemTemplate>  <asp:Label ID="lblStatus" runat="server" CausesValidation="false"  CssClass="txt" Text='<%# Bind("status") %>'></asp:Label></ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

推荐答案

// add RowDataBound event to your gridview
<asp:gridview id="GridCall" onrowdatabound="GridCall_RowDataBound" ...>
...
</asp:gridview>

//server side
protected void GridCall_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
         Label lblStatus= (Label)e.Row.FindControl("lblStatus");
         if(lblStatus.Text == "hold")
         {
              lblStatus.ForeColor = System.Drawing.Color.Yellow;
         }
         else if(lblStatus.Text == "unsolved")
         {
              lblStatus.ForeColor = System.Drawing.Color.Red;
         }
    }
}
