推荐答案

您可以建立的OnClientClick 的全部内容为code括号内的字符串，并将其会喜欢你的输出是期待的。

You can build the entire contents of OnClientClick as a string within the code brackets and it will output like you're expecting.

<asp:LinkButton runat="server" ID="lbtnEdit" Text="edit" 
    OnClientClick='<%# "msgDisp(" + Eval("LocationId") + ");" %>' /> 

这是假设LocationId是一个有效的号码 - 没有引号来包装你的价值，当它呈现，所以输出像 msgDisp（你好）; 将要打破。我不知道如何解决，在这种方式下，所以如果你有这样做，我会建议设置的OnClientClick 在服务器端的的ItemDataBound 事件。下面是它想什么如果母公司是转发控制。

This is assuming LocationId is a valid number- there are no quote marks to wrap your value when it renders, so outputting something like msgDisp(hello); is going to break. I don't know how to address that in this manner, so if you have to do that I would recommend setting OnClientClick server side during the ItemDataBound event. Here's what it would like where the parent is a Repeater control.

protected void notesRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    MyClass item = (MyClass)e.Item.DataItem;
    LinkButton lbtnEdit = (LinkButton)e.Item.FindControl("lbtnEdit");
    lbtnEdit.OnClientClick = string.Format("msgDisp('{0}');", item.LocationId);
}
