C# 4.0 如何在C中根据条件更改GridView行颜色#

我想根据某些条件更改gridview的特定行颜色，我正在使用ASP.NET和c#。 以下是示例输出：

提前感谢

正如蒂姆所说，使用RowDataBound

Html:

数据层类

    public class DataStructure
{
    public string BusinessIdentifier { get; set; }

    public string SLA { get; set; }

    public DataStructure()
    {


    }
}

public class DataForGrid
{
    public DataForGrid()
    {
        this.Stuff = new List<DataStructure>();

        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName1", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "Taskname2", SLA = null });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName3", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName4", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName5", SLA = "1.2" });

    }
    public List<DataStructure> Stuff { get; set; }

    public List<DataStructure> Get()
    {




        return this.Stuff;
    }
}

公共类数据结构
{
公共字符串BusinessIdentifier{get；set；}
公共字符串SLA{get；set；}
公共数据结构（）
{
}
}
公共类DataForGrid
{
公共数据格式（）
{
this.Stuff=新列表（）；
this.Stuff.Add（新数据结构{BusinessIdentifier=“TaskName1”，SLA=“1.2”}）；
this.Stuff.Add（新数据结构{BusinessIdentifier=“Taskname2”，SLA=null}）；
this.Stuff.Add（新数据结构{BusinessIdentifier=“TaskName3”，SLA=“1.2”}）；
this.Stuff.Add（新数据结构{BusinessIdentifier=“TaskName4”，SLA=“1.2”}）；
this.Stuff.Add（新数据结构{BusinessIdentifier=“TaskName5”，SLA=“1.2”}）；
}
公共列表内容{get；set；}
公共列表Get（）
{
归还这个东西；
}
}

使用

行数据绑定

事件。您可以使用这些行来获取底层的

数据源

：

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // modify it accoording to your datasource, use the debugger if you're not sure
        DataRow row = ((DataRowView)e.Row.DataItem).Row;
        // just an example:
        bool redCondition = row.Field<string>("SomColumn") == "Some Value";
        e.Row.BackColor = redCondition ? Color.Red : GridView1.RowStyle.BackColor;
    }
}

受保护的无效gridview1\u行数据绑定（对象发送方，GridViewRowEventArgs e）
{
如果（e.Row.RowType==DataControlRowType.DataRow）
{
//根据您的数据源修改它，如果您不确定，请使用调试器
DataRow row=（（DataRowView）e.row.DataItem）.row；
//举个例子：
bool redCondition=row.Field（“SomColumn”）=“Some Value”；
e、 Row.BackColor=redCondition？Color.Red:GridView1.RowStyle.BackColor；
}
}

这是一个ASP.NET网格

    protected void TaskNameGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        var d = (DataStructure)e.Row.DataItem;

        if (string.IsNullOrEmpty(d.SLA))
        {
            e.Row.BackColor = System.Drawing.Color.Red;

        }
    }
}

    public class DataStructure
{
    public string BusinessIdentifier { get; set; }

    public string SLA { get; set; }

    public DataStructure()
    {


    }
}

public class DataForGrid
{
    public DataForGrid()
    {
        this.Stuff = new List<DataStructure>();

        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName1", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "Taskname2", SLA = null });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName3", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName4", SLA = "1.2" });
        this.Stuff.Add(new DataStructure { BusinessIdentifier = "TaskName5", SLA = "1.2" });

    }
    public List<DataStructure> Stuff { get; set; }

    public List<DataStructure> Get()
    {




        return this.Stuff;
    }
}

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // modify it accoording to your datasource, use the debugger if you're not sure
        DataRow row = ((DataRowView)e.Row.DataItem).Row;
        // just an example:
        bool redCondition = row.Field<string>("SomColumn") == "Some Value";
        e.Row.BackColor = redCondition ? Color.Red : GridView1.RowStyle.BackColor;
    }
}
