如何在行中绘制单元格(Telerik)？

Question

接下来我将编写处理fowFormatting my cells的代码：

private void gridViewRaces_RowFormatting(object sender, RowFormattingEventArgs e)
    {
        foreach (var cellColumn in e.RowElement.Data.Cells)
        {
            var cellInfo = cellColumn as GridViewCellInfo;
            if (cellInfo != null)
            {
                cellInfo.Style.DrawFill = true;
                if (cellInfo.ColumnInfo.Name == "columnContactProducerName")
                {
                    cellInfo.Style.DrawFill = true;
                    cellInfo.Style.BackColor = Color.Yellow;
                }
                else if (cellInfo.ColumnInfo.Name == "columnTransport")
                {
                    cellInfo.Style.BackColor = Color.Yellow;
                }
                else
                {
                    cellInfo.Style.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
                }
            }

        }
        //e.RowElement.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
    }

但我的细胞不会画画。如何在dataBinding上画一些行中的单元格？

Answer 1

看起来做这件事的合适事件是ItemDataBound事件。请看这里：

http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/appearance-and-styling/conditional-formatting

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
//Is it a GridDataItem
if (e.Item is GridDataItem)
{
    //Get the instance of the right type
    GridDataItem dataBoundItem = e.Item as GridDataItem;

    //Check the formatting condition
    if (int.Parse(dataBoundItem["Size"].Text) > 100)
    {
        dataBoundItem["Received"].ForeColor = Color.Red;
        dataBoundItem["Received"].Font.Bold = true;
        //Customize more...
    }
}
}

或者更好的方法是使用自定义的CSS类，这样以后就可以进行更改，而不必重新构建项目：

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e){
if (e.Item is GridDataItem)
{
    GridDataItem dataItem = e.Item as GridDataItem;
    if (dataItem["Country"].Text == "Mexico")
        dataItem.CssClass = "MyMexicoRowClass";
}
}
