在网格视图中查找控件

Question

我有代码在gridview中找到标签,我检查了它,s标签文本,它给了我索引而不是文本和这个错误apear对象参考不设置为.....所以我想给CU.Username = LBL.文本; 文本没有控制代码索引

protected void GridView1_RowUpdated(object sender, GridViewUpdatedEventArgs e)
{                
    LblRseult.Visible = true;
    LblRseult.Text = "Successfully Process";
}

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    cUser CU = new cUser(this);

    LBL = (Label)GridView1.Rows[e.RowIndex].Cells[1].FindControl("Label1");
    CU.Username = LBL.Text;
    if (CU.BasiclyExists())
    {
        LblRseult.Visible = true;
        LblRseult.Text = "This user already exists";
    }     
}

您可以通过以下方式访问TemplateField中的控件:

Label lbl = GridView1.Rows[e.RowIndex].FindControl("Label1") as Label;
