问题描述

大家好，

我是新的ASP.NET开发人员.我现在正在使用DetailsView从数据库中分发一些数据.我需要突出显示DetailsView中的某些两行.两行都是VARCHAR数据类型.

Hello everybody,

I am a new ASP.NET developer. I am using a DetailsView now to dispaly some data from the database. I have the need to highlight certain two rows from the DetailsView. Both rows are VARCHAR data type.
SO HOW TO DO THAT?

推荐答案

重写数据绑定事件并设置e.Row.BackColor = System.Drawing.Color.Red;.或任何一种颜色，如果您需要执行一些逻辑来查找需要突出显示的行.

Override the databound event and set the e.Row.BackColor = System.Drawing.Color.Red; or what ever color, if you have some logic to execute for finding the row that needs to be highlighted.

protected void detailsView_RowDataBound(object sender, 
GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if(...)//some condition for selection of row to be higlighted
        {
           e.Row.BackColor = System.Drawing.Color.Red;
        }
}
}

如果您需要一个垂直的行，比如说要突出显示第4行，然后将其固定，那么您可以直接这样

If you need a perticular row, say 4th row to be highlighted and that''s fixed then you could directly like this

detailsViewGrid.Rows[2].Row.BackColor = System.Drawing.Color.Red;

您唯一需要记住的是，此代码仅在 DetailsView_rowdatabound事件(如预渲染)之后发生的那些事件中编写.

The only thing you need to keep in mind that this code would be written in only those events which would come after detailsView_rowdatabound event(Like pre-render)
