Question

我在asp.net项目中使用gridview控件的自动编辑按钮。我单击编辑按钮时会遇到问题，它会触发gridview的rowcommand事件和rowediting事件，但是当我再次单击编辑按钮时，网格行却未进入编辑模式，现在网格行进入了编辑模式问题是为什么我需要单击两个编辑按钮次。

这是我的html（aspx）代码。

将.DataBind添加到GridView1_RowEditing中：

protected void Page_Load(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    dt.Columns.AddRange(new DataColumn[1] { new DataColumn("empno", typeof(int)) });
    for (int i = 0; i < 10; i++)
    {
        DataRow dr;
        dr = dt.NewRow();
        dr["empno"] = i.ToString("00");

        dt.Rows.Add(dr);

        GridView1.DataSource = dt;
        Session["dt"] = dt;
        GridView1.DataBind();
    }
}

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
    GridView1.EditIndex = e.NewEditIndex;
    GridView1.DataSource = Session["dt"] as DataTable;
    GridView1.DataBind();
}
