DataGrid 查找控件

发布于 2024-08-13 17:23:47 字数 912 浏览 3 评论 0原文

嗨，

我有一个 DataGrid （是的，如果它是一个 gridview 会更好，但我对此无能为力）

在 itemDataBound 事件中我在每行的第一个单元格中添加一个隐藏字段我根据某些内容设置其 ID，然后将其 clientID 保存在列表中，以便稍后尝试从中获取值，

但尝试使用 findcontrol 找不到任何内容，

尝试过

这里是 itemdatabound 位

foreach(page in datasource){
HiddenField hidOrder = new HiddenField();
hidOrder.ID = "order_" + page.Id.ToString();
hidOrder.Value = page.Ordering.ToString();
e.Item.Cells[0].Controls.Add(hidOrder);
idList.Add(hidOrder.ClientID);
}

，然后这是一个按钮单击活动..

int numRows = FrontEndDataGrid.Items.Count;
for (int i = 0; i < numRows; i++){
  foreach(string hidID in idList){
    HiddenField hf = FrontEndDataGrid.Items[i].FindControl(hidID) as HiddenField;
    //ssadly this never finds anything
    //have also tried looping around the cells for each 'row' - no luck there either
  }
}

有什么想法吗？

谢谢纳特

原文

I have a DataGrid (yes would be nicer if it was a gridview but nothing i can do about that)

in the itemDataBound event i am adding a hidden field into the first cell of each row
I am setting its ID based on something, and then saving its clientID in a List for later attempts to get the value from it

but try as i might i cant find anything with findcontrol

have tried

here is the itemdatabound bit

foreach(page in datasource){
HiddenField hidOrder = new HiddenField();
hidOrder.ID = "order_" + page.Id.ToString();
hidOrder.Value = page.Ordering.ToString();
e.Item.Cells[0].Controls.Add(hidOrder);
idList.Add(hidOrder.ClientID);
}

then this is a button click event..

int numRows = FrontEndDataGrid.Items.Count;
for (int i = 0; i < numRows; i++){
  foreach(string hidID in idList){
    HiddenField hf = FrontEndDataGrid.Items[i].FindControl(hidID) as HiddenField;
    //ssadly this never finds anything
    //have also tried looping around the cells for each 'row' - no luck there either
  }
}

any ideas?

thanks
