I have some ASP.NET code that dynamically generates rows and cells for a Table control on the page.
我有一些ASP.NET代码,可以为页面上的Table控件动态生成行和单元格。
I have specifically set the ID of each cell, but I am having trouble getting FindControl to actually find them.
我已经专门设置了每个单元格的ID,但是我无法让FindControl实际找到它们。
Here's the code that I use to create the cells:
这是我用来创建单元格的代码:
tbc = New TableCell
tbr.Cells.Add(tbc)
tbc.ID = String.Format("tc_{0}-{1}-{2}", curStartDate.Day, curStartDate.Month, curStartDate.Year)
Just below that, I try to find the control with the following:
就在下面,我尝试使用以下内容找到控件:
Dim ctlName As String = String.Format("tc_{0}-{1}-{2}", curStartDate.Day, curStartDate.Month, curStartDate.Year)
Dim ctl As Control = tblAllocations.FindControl(ctlName)
I have tried swapping the line that declares the ID, with the line that adds the cell to the Cells collection of the TableRow, and that makes it work. But throughout my application, I have the statements in the order as above, and they works fine (FindControl can find the control with the correct ID).
我已经尝试交换声明ID的行,以及将单元格添加到TableRow的Cells集合中的行,这使它工作。但是在我的应用程序中,我按照上面的顺序进行了语句,并且它们工作正常(FindControl可以找到具有正确ID的控件)。
Is there something obvious I am missing?
有什么明显的东西我不见了吗?

When you say "just below that" have you added the tbr to the tblAllocations.Rows yet? If not that would be the reason it can't be found.
当你说“只是低于那个”时你已经将tbr添加到了tblAllocations.Rows了吗?如果不是那就是它无法找到的原因。
