找不到内部进行的GridView事件FormView的编辑模式控制面板 [英] Can't find panel control inside formview Edit mode with Gridview event
问题描述
我有一个面板可见=假。我有逻辑，应该使面板可见，如果条件得到满足。
我无法找到面板我猜这是因为它是不可见的。也许我会尝试另一个事件，看看我应该使面板可见那里。像数据绑定的事件吗？
更新****************
每在注释下使用显示：无
很好的建议。我想肯定有人会解决我的问题。做几件事情后，但是，我不能让面板风格=显示：无，甚至隐藏面板。我知道我在编辑正确的面板，因为我改变了文本中。
我已经做了几件事情，如在ItemCommand事件的顶视图状态禁用硬codeD在code前面板风格，add.attribute（风格，块），在放一パ思考我有莫名其妙的东西覆盖的知名度....
更新＃2 ***************
我完全难倒......这一切都应该工作......于是，我做了一些进一步的谷歌搜索。现在，我可能已经离开了一些重要的信息，不知道它重要的。
- 我有一个网格视图
- 下面的表格是由selectedIndex事件产生
- 我试着从以下职位，但没有喜悦实施
<一href=\"http://stackoverflow.com/questions/3862397/i-cannot-change-controls-visibility-on-c-sharp-$c$c\">I不能改变C＃code 控制的知名度
测试结果：
- 编辑命令是越来越正常解雇
- 我删除比这个地区之外的任何控件
- 外UpdatePanel的一个面板可以改变
- 我改变了更新面板的UpdateMode为条件，以确保没有别的覆盖
尽管我知道这个面板只存在在这一点上，因为我只是说了。
那么，这事与GridView的？这是我补充它在下面

解决它。该形式是在生命周期为时尚早。在数据绑定事件，检查如果CURRENTMODE是编辑，然后我做了我的数据检查

I have a Panel visible=false. I have logic that should make the panel viewable if condition is met. I can't locate the the panel I'm guessing it's because it's not visible. Maybe I'll try on another event and see if I should make the panel visible there. Like the Databound event?
UPDATE**************** Per the comment below on using display:none excellent suggestion. I thought for sure it was going to fix my issue. However after doing several things, I cannot get the panel style="display:none" to even hide the panel. I know I am in the correct panel on edit as I changed text inside.
I've done several things such as disabled viewstate, hardcoded the style in the code front panel, add.attribute("style",block) at the top of the itemcommand event, put in a testPanel thinking I had something overwriting the visibility somehow....
UPDATE #2*************** I'm totally stumped... This all SHOULD work... So, I did some further googling. Now I may have left out some important information not knowing that it mattered. - I have a grid view - The form below is produced by the selectedindex event - I tried to implement from the following post but no joy I cannot change control's visibility on C# code
TESTING RESULTS: - The Edit Command is getting fired properly - I removed any controls other than this pacific one - A panel OUTSIDE the updatepanel can be changed - I changed the Update Panel "UpdateMode" to Conditional to make sure nothing else was overwriting even though I know this panel only exists at this point since I just added it.
So is it something with the gridview? Which I added it in below

Resolved it. The form was too early in the lifecycle. in the Databound event, checked if the currentMode was in edit, then I did my checks on the data
protected void fvWasteCollected_DataBound(object sender, EventArgs e)
{
FormView formview = fvWasteCollected;
FormViewRow row = fvWasteCollected.Row;
DataRowView rowview = (DataRowView)fvWasteCollected.DataItem;
Panel pnlOtherContractor = (Panel)fvWasteCollected.FindControl("pnlOtherContractor2");
if (fvWasteCollected.CurrentMode == FormViewMode.Edit)
{
var s_contractorId = rowview["MRWContractorId"].ToString();
if (s_contractorId == "0")
{
pnlOtherContractor.Visible = true;
}
else
{
pnlOtherContractor.Visible = false;
}
}
}
