從GridView ASP.NET C＃外部的按鈕更改標簽文本

Question

下面的代碼僅適用於GridViewCommandEventArgs但這次我想在單擊按鈕時使用這種方法。 我如何修改此代碼以便將其用於按鈕單擊。 即時通訊正在研究使用gridview外部的按鈕更改文本。

GridViewRow row = (GridViewRow)((Button)e.CommandSource).NamingContainer;
Label label = row.FindControl("lbl_reviewDate") as Label;
label.Text = DateTime.Now.Date.ToString("d");
Label labelID = row.FindControl("lbl_id") as Label;

Answer 1

我希望這有幫助：

  protected void btn_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow row in YourGridviewName.Rows)
        {

          Label label = row.FindControl("lbl_reviewDate") as Label;
          label.Text = DateTime.Now.Date.ToString("d");
          Label labelID = row.FindControl("lbl_id") as Label;
        }
    }
