            {
                if (DataBinder.Eval(e.Row.DataItem, "TotalLeave") != null)                
                {
                    if (DataBinder.Eval(e.Row.DataItem, "TotalLeave").ToString() != "0")
                    {
                        Label lblTotalLeave = (Label)e.Row.FindControl("lblTotalLeave");
                        lblTotalLeave.Text = DataBinder.Eval(e.Row.DataItem, "TotalLeave").ToString();
                    }

                if (DataBinder.Eval(e.Row.DataItem, "colorcode").ToString() != "0")
                {
                    Label lblTotalLeave = (Label)e.Row.FindControl("lblColour");
                    lblTotalLeave.Text = System.Drawing.Color.FromName(DataBinder.Eval(e.Row.DataItem, "colorcode").ToString());
                }
            }
        }

推荐答案

您可以使用设置标签的背景颜色以下电话：

You can set the background color of the label by using below call:

lblTotalLeave.BackColor = System.Drawing.Color.FromName( DataBinder.Eval( e.Row.DataItem, "colorcode" ).ToString() );

lblTotalLeave.Text = System.Drawing.Color.FromName( DataBinder.Eval( e.Row.DataItem, "colorcode" )).Name.ToString();

我相信这会解决你的问题问题。

I am sure this will solve your problem.

protected void gvAbsenceTypes_RowDataBound（object sender，GridViewRowEventArgs e）

{

if（e.Row.RowType == DataControlRowType .DataRow）

{

if（DataBinder.Eval（e.Row.DataItem，TotalLeave）！= null）

{

if（DataBinder.Eval（e.Row.DataItem，TotalLeave）。ToString（）！=0）

{

标签lblTotalLeave =（标签）e.Row.FindControl（lblTotalLeave）;

lblTotalLeave.Text = DataBinder.Eval（e.Row.DataItem，TotalLeave）。ToString（）;

}

}



if（DataBinder.Eval（e.Row.DataItem，colorcode）。ToString （）！=0）

{

标签lblTotalLeave =（标签）e.Row.FindControl（lblCo lour）;

lblTotalLeave.Style.Add（background-color，+ DataBinder.Eval（e.Row.DataItem，colorcode）。ToString（）+）;

lblTotalLeave.Style.Add（color，+ DataBinder.Eval（e.Row.DataItem，colorcode）。ToString（）+）;

lblTotalLeave.text = DataBinder.Eval（e.Row.DataItem，colorcode）。ToString（）;

}

}

}

protected void gvAbsenceTypes_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (DataBinder.Eval(e.Row.DataItem, "TotalLeave") != null)
{
if (DataBinder.Eval(e.Row.DataItem, "TotalLeave").ToString() != "0")
{
Label lblTotalLeave = (Label)e.Row.FindControl("lblTotalLeave");
lblTotalLeave.Text = DataBinder.Eval(e.Row.DataItem, "TotalLeave").ToString();
}
}

if (DataBinder.Eval(e.Row.DataItem, "colorcode").ToString() != "0")
{
Label lblTotalLeave = (Label)e.Row.FindControl("lblColour");
lblTotalLeave.Style.Add("background-color",""+DataBinder.Eval(e.Row.DataItem, "colorcode").ToString()+"");
lblTotalLeave.Style.Add("color",""+DataBinder.Eval(e.Row.DataItem, "colorcode").ToString()+"");
lblTotalLeave.text=DataBinder.Eval(e.Row.DataItem, "colorcode").ToString();
}
}
}

不需要行数据绑定只需将backcolor绑定到标签，因为它是数据库中的一个字段

。在gridview模板字段中，您可以在标签道具中执行此操作。将哈希值放在数据库中的colorcode之前或（如果db中没有带颜色代码的哈希符号，则使用String.Formate）。这是简单的方法

喜欢这个

no need in row databound just bind the backcolor with label as it is a field in database
. In gridview template field you can do it in the label props. put hash before the colorcode in database or (use String.Formate if there is no hash symbol with colorcode in db). this is the easy approach
like this

<asp:label id="lblColour" backcolor="<%#Eval("colorcode") %>" runat="server" xmlns:asp="#unknown"></asp:label>
