推荐答案

您好，Carlos，我知道您正在尝试从代码动态创建控件并将其设置为文本和命令参数. br/> 尽管我的回答不能直接说出您的代码为什么失败，但是我宁愿使用下面的代码(在vb.net中):

Hi Carlos, I understood that you are trying to create the controls dynamically from code and setting it text and command argument.
Although my answer is not straight to say why your code is failing, but I would rather prefer using the below code (in vb.net):

For I As Integer = 0 To 30
    Dim lb As New LinkButton()
    lb.Text = I.ToString()
    lb.CommandName = "Dia"
    lb.CommandArgument = I.ToString()
    lb.Command += New CommandEventHandler(lb_Command)
    form1.Controls.Add(lb)
Next
