当在GridView中单击更新按钮时，将激发RowEditing

我创建了一个GridView，如下所示：

protected void Page_Load(object sender, EventArgs e)
{
    GridView gv = new GridView();
    gv.ID = pId.ToString();
    gv.AutoGenerateEditButton = true;
    gv.DataKeyNames = ids;
    gv.RowEditing += gv_RowEditing;
    gv.RowUpdating += gv_RowUpdating;
    bindGv(pId, gv);
}

我还写了以下方法：-

RowUpdating:

void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    GridView gv = sender as GridView;
    GridViewRow row = (GridViewRow)gv.Rows[e.RowIndex];
    ProductCategory pc = context.ProductCategories.First(s => s.Name ==gv.ID );
    TextBox txtName = row.FindControl("txtName") as TextBox;
    pc.Name = txtName.Text;
}

RowEditing:

void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
    GridView gv = sender as GridView;
    gv.EditIndex = e.NewEditIndex;
    bindGv(Convert.ToInt32(gv.ID), gv);
}

但是，当我在调试模式下运行代码时，单击更新按钮会调用gv_RowEditing方法，而不是gv_RowUpdating。问题出在哪里？

当在GridView中单击更新按钮时，将激发RowEditing

当您单击编辑按钮更新它调用的任何记录时，触发gridview的事件的顺序，之后当您单击更新按钮时，它调用rowupdateing事件。rowiting事件总是先调用，然后再调用rowupdateing。
