向RowDataBound中的gridview行添加第二个类 [英] Adding second class to gridview row in RowDataBound

问题描述

我希望以编程方式向GridView添加一个附加类.我知道我可以使用以下代码来做到这一点:

I wish to add an additional class to a GridView programatically. I know I can do this using the following code:

public void RowDataBound(object sender, GridViewRowEventArgs e)
{
    DataRow row = ((DataRowView)e.Row.DataItem).Row;
    if (!row.Field<Boolean>("IsActive"))
    {
        e.Row.Attributes["class"] += "InActive";
    }
}

，它工作正常.但是，在交替的行上添加了"IsActive"类，最终得到了以下HTML:

and it works fine. The class "IsActive" is added, however, on alternating rows I end up with this HTML:

<tr class="gvAlternatingStyle" class="InActive"
    onmouseover="gvMouseOver(this)" 
    onmouseout="gvMouseOut(this)" style="cursor:pointer;">

两个类定义不是我想要的.我希望有这样的东西:

Two class definitions is not what I want. I would prefer to have something like this:

<tr class="gvAlternatingStyle InActive"
    onmouseover="gvMouseOver(this)" 
    onmouseout="gvMouseOut(this)" style="cursor:pointer;">

这当然更有效.

我似乎无法弄清楚在何处/如何调整此html.可能在OnPreRender()中，但是我看不到哪里.谁能给我指点?

I cannot seem to figure out where/how to adjust this html. Possibly in OnPreRender() but I don't see where. Can anyone give me a pointer?

推荐答案

对此进行了一段时间的摸索，并在VDWWD的帮助下，我研究了如何结合上述和OnPreRender()来实现这一点:

After muddling with this a while and with help from VDWWD I worked out how to accomplish this with a combination of the above and OnPreRender():

    public void RowDataBound(object sender, GridViewRowEventArgs e)
    {
            DataRow row = ((DataRowView)e.Row.DataItem).Row;
            if (!row.Field<Boolean>("IsActive"))               {
                e.Row.Attributes["class"] += "InActive";                
    }


    protected void PreRender(object sender, EventArgs e)
    {
        foreach(GridViewRow row in GridView1.Rows)
        {
            if ((row.Attributes["class"] == "InActive")&& 
                (row.RowState == DataControlRowState.Alternate)){
                row.RowState = DataControlRowState.Normal;
                row.Attributes["class"] = "gvAlternatingStyle InActive";

            }

        }
    }
