基于Gridview的RowDataBound事件中的行数据的单元格条件输出 [英] Conditional output in cell based on row data in Gridview's RowDataBound event

问题描述

我有一个位值(黑色)我想在gridview中显示它的状态，好像它是真的，行显示是"，否则行显示否"，这是我的代码，但结果不正确，因为我的代码显示所有行是"如果一个值为真，我想显示每一行状态

i have a bit value (Black) i want to display its status in gridview as if its true, the row display "Yes", otherwise the row display "No", this is my code, but the result is not right, cuz my code display all rows "Yes" if one value is true, i want to display each row status

    protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataTable dt = GetData();
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                Boolean bitBlack = Convert.ToBoolean(dt.Rows[i]["Black"]);
                if (bitBlack)
                {
                    e.Row.Cells[7].Text = ("Yes");
                }
                else
                {
                    e.Row.Cells[7].Text = ("No");
                }
            }
        }
    }

推荐答案

您始终可以使用 DataItem 获取底层DataSource:

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRow row = ((DataRowView)e.Row.DataItem).Row;
        bool isBlack = row.Field<bool>("Black");
        e.Row.Cells[7].Text = isBlack ? "Yes" : "No";
    }
}
