Question

我试图通过点击放置在gridview内的ImageButton来从gridview中删除行。我正在获取行索引，但不知道如何删除。我的gridview从会话绑定，我不想重新绑定gridview。

这是我的代码：

protected void GVDetail_RowCommand(object sender, GridViewCommandEventArgs e)
  {
    if (e.CommandName.Equals("Remove"))
    {
      List<Class1> list = (List<Class1>)Session["value1"];
      int index = Convert.ToInt32(e.CommandArgument);
      GridViewRow gridRow = gvDetail.Rows[index];// (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);

      ((List<Class1>)Session["value1"]).RemoveAt(index);
    }
  }

如果有人对此有任何想法，请帮助我..

Answer 1

使用gridview删除方法。

void GVDetail_RowCommand_RowCommand(Object sender, GridViewCommandEventArgs e)
{
if(e.CommandName=="Remove")
{
     var id = Int32.Parse(e.CommandArgument);
     GVDetail.DeleteRow(id);

 }
}

protected void GVPurchaseOrderTax_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    try
    {
        if (dt.Rows.Count > 0)
        {
            dt.Rows[e.RowIndex].Delete();
            GVPurchaseOrderTax.DataSource = dt;
            GVPurchaseOrderTax.DataBind();
        }
    }
}

如何在行命令事件中从gridview中删除行？
