c# - 如何从客户端脚本访问参数

我有一个Gridview并在rowDatabound上单击该行创建
显示模式弹出窗口。我想要的是当单击该行时，应该传递该行的ID。

protected void grdOrderProduct_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#ceedfc'");
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''");
        e.Row.Attributes.Add("style", "cursor:pointer;");
        e.Row.Attributes["onClick"] = Page.ClientScript.GetPostBackClientHyperlink(btnPop, "12");
    }
}

我如何在服务器控件上获取此“ 12”。我已经把12作为静态演示。但它会改变。

最佳答案

要知道单击了哪一行，必须使用Row的GridViewRowEventArgs属性。

    protected void grdOrderProduct_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#ceedfc'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''");
            e.Row.Attributes.Add("style", "cursor:pointer;");
            e.Row.Attributes["onClick"] = Page.ClientScript.GetPostBackClientHyperlink(btnPop, e.Row.RowIndex.ToString());

        }
    }

RowIndex将作为参数传递给btnPop。为了接收它，btnPop应该实现IPostBackEventHandler。

像这样：

public class MyControl : Button, IPostBackEventHandler
  {

    // Use the constructor to defined default label text.
    public MyControl()
    {
    }

    // Implement the RaisePostBackEvent method from the
    // IPostBackEventHandler interface.
    public void RaisePostBackEvent(string eventArgument)
    {
      //You receive the row number here.
    }
  }
