ItemDataBound C#ASP.net上的方法用法

本文关键字：方法 用法 C#ASP net ItemDataBound | 更新日期: 2023-09-27 17:58:58

我有一个方法可以在ItemDataBound上使用；

 static void getPhoto() {
    Fonksiyonlar vt=new Fonksiyonlar();
    DataTable SeriFoto = vt.GetDataTable("select foto from seriFotograf where seriilanID=" + DataBinder.Eval(e.Item.DataItem, "ilan_id") + " and kapak=true" + " order by seriilanID desc");
    if (SeriFoto.Rows.Count < 1)
    {
        DataRow nullPhotoRow;
        nullPhotoRow = SeriFoto.NewRow();
        nullPhotoRow["foto"] = "0.png";
        SeriFoto.Rows.Add(nullPhotoRow);
    }
    Repeater rptReddedilenFoto = (Repeater)e.Item.FindControl("rptReddedilenFoto");
    rptReddedilenFoto.DataSource = SeriFoto;
    rptReddedilenFoto.DataBind();
}

但是我得到一个错误：

名称"e"在当前上下文中不存在

这些代码运行正常，但它不在方法中。

最简单的方法是，将DataGridItem传递给此方法（如果是GridView，则传递GridViewRow）：

static void getPhoto(DataGridItem item) {
    DataRowView view = (DataRowView) item.DataItem;
    Fonksiyonlar vt=new Fonksiyonlar();
    DataTable SeriFoto = vt.GetDataTable("select foto from seriFotograf where seriilanID=" + view["ilan_id"] + " and kapak=true" + " order by seriilanID desc");
    if (SeriFoto.Rows.Count < 1)
    {
        DataRow nullPhotoRow = SeriFoto.NewRow();
        nullPhotoRow["foto"] = "0.png";
        SeriFoto.Rows.Add(nullPhotoRow);
    }
    Repeater rptReddedilenFoto = (Repeater)item.FindControl("rptReddedilenFoto");
    rptReddedilenFoto.DataSource = SeriFoto;
    rptReddedilenFoto.DataBind();
}
