程序内部生成的LinkButton，怎么增加一个Onclick事件？（在线等待）

[jackiedlh]

我根据数据库表的记录生成一些linkButton，但不知如何相应用户的点击进行一些处理？
谁有自定义事件的经验？高分求救！！

VB.net
Dim btn As New Button()
btn.Text = "Button1"
Me.Controls(1).Controls.Add(btn)
AddHandler btn.Click AddressOf Button1_Click

C#

LinkButton.Onclick += new System.EventHandler(处理函数名);

[luckysusan]

sorry!

C#

LinkButton.Click += new System.EventHandler(处理函数名);

[rabbitwy]

控件生成后加上（假设控件名为lb）
lb.Click += new System.EventHandler(this.lb_Click);

在private void lb_Click(object sender, System.EventArgs e)
{
}
添加你的处理代码,sender.ToString()就是你所点击的LINKBUTTON控件的名字。

protected System.Web.UI.WebControls.Label Label1;
public void Page_Load(object sender, System.EventArgs e)
{
LinkButton myLinkButton = new LinkButton();
myLinkButton.ID = "myLink";
myLinkButton.Text = "myLink";
myLinkButton.Click += new EventHandler(this.Process);
this.Controls[1].Controls.Add(myLinkButton);
}

private void Process(object sender,EventArgs e)
{
Label1.Text = "点击了连接按钮";
}

Sub getACC(ByVal strAA As String)
Dim lbtnAA As New System.Web.UI.WebControls.LinkButton()
lbtnAA.Text = strAA
lbtnAA.ForeColor = System.Drawing.Color.Blue
AddHandler lbtnAA.Click, AddressOf ButtonClickHandler
Table2.Rows(0).Cells(0).Controls.Add(lbtnAA)
End Sub

Private Sub ButtonClickHandler(ByVal sender As Object, ByVal e As System.EventArgs)
Dim lbtnMy As LinkButton = CType(sender, LinkButton)
Label1.Text = lbtnMy.Text
End Sub

谢谢大家！

我试了一下，点击linkbutton没有进入事件处理，怎么回事？

[jackiedlh]

贴源码

for (int i=0;i<dt.Rows.Count;i++){
cellItem = new TableCell();
btnItem = new LinkButton();
btnItem.ID=dt.Rows[i]["CategoryId"].ToString();
btnItem.Text = dt.Rows[i]["Description"].ToString();
btnItem.Click += new EventHandler(ShowSubItem);

cellItem.Controls.Add(btnItem);
rowItem.Cells.Add(cellItem);

this.tblPermission.Rows.Add(rowItem);
}

private void ShowSubItem(object sender, System.EventArgs e)
{
string s=sender.ToString();
}

单步调试，没有进入事件呀！

要把下面代码写在Page_Init过程中




for (int i=0;i<dt.Rows.Count;i++){
cellItem = new TableCell();
btnItem = new LinkButton();
btnItem.ID=dt.Rows[i]["CategoryId"].ToString();
btnItem.Text = dt.Rows[i]["Description"].ToString();
btnItem.Click += new EventHandler(ShowSubItem);

cellItem.Controls.Add(btnItem);
rowItem.Cells.Add(cellItem);

this.tblPermission.Rows.Add(rowItem);
}

[kknew]

btnItem = new LinkButton();
btnItem.Attributes.Add("onclick","javascript:window.alert('')");
