TabPage inside TabPage中的Controls.Find

Question

我在TabControl1中有一个TabControl2。TabControl2在TabControl1的所有TabPages中。在TabControl2的TabPage是DataGridView，我需要与此DataGridView工作(Add.Rows等)。所有内容都是通过编程添加的。

我正在寻找找到合适的DataGridView的最佳方法，所以我需要类似这样的东西：

DataGridView xxx = TabControl2.SelectedTab.Controls.Find("data_grid_view_name", false).FirstOrDefault() as DataGridView ***in TabControl1.SelectedTab***
Find this DataGridView by more :

Foreach (var y in TabControl1.Controls.OfType<Tabpage>())
{
//looks like a dirty code for me
}

Answer 1

此Linq查询返回嵌套TabControls中的第一个DataGridView

var gridViews = from tp in this.tabControl1.TabPages.Cast<TabPage>()
                from tc in tp.Controls.OfType<TabControl>()
                from tp2 in tc.TabPages.Cast<TabPage>()
                from grid in tp2.Controls.OfType<DataGridView>()
                select grid;
DataGridView firstGrid = gridViews.FirstOrDefault();
// if(firstGrid != null) ...

Answer 2

我认为最直接的方法是：

tabControl1.Controls.Find("data_grid_view_name", true);

Answer 3

另一个例子：

string dgvName = "data_grid_view_name";
if (tabControl1.SelectedTab != null)
{
    var nestedTabControl = (from TC in tabControl1.SelectedTab.Controls.OfType<TabControl>() select TC).FirstOrDefault();
    if (nestedTabControl != null && nestedTabControl.SelectedTab != null)
    {
        Control[] matches = nestedTabControl.SelectedTab.Controls.Find(dgvName, true);
        if (matches.Length > 0 && matches[0] is DataGridView)
        {
            DataGridView dgv = (DataGridView)matches[0];
            // ... do something with "dgv" ...
        }
    }
}
