我想在 WPF 中创建一个与 windows 应用程序相同的应用程序。当我在 wpf 中使用 treeview 事件时，我没有找到任何类似于 WIndows 应用程序的 treeview_NodeMouseClick 的事件。
//Windows 应用程序代码
private void tv_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
if (e.Node != null)
{
GetAllchield(e.Node, e.Node.Level);
}
}
// GetAllchield
public void GetAllchield(TreeNode clickednode, int indexDepth)
{
if (clickednode.Nodes.Count > 0 && !clickednode.IsExpanded)
{
clickednode.Collapse();
return;
}
string[] FullPath = clickednode.FullPath.Split('\\');
string rootnode = FullPath[0].ToString();
//get all market for root event type
int eventTypeID = DictionaryAllActiveEventTypes[rootnode];
string[] allMarkets = GetAllMarketForEventID(eventTypeID);
//selecting unque chield node and populating in tree
for (int i = 0; i < allMarkets.Length; i++)
{
if (allMarkets[i].Contains(clickednode.Text))
{
string[] marketDetails = allMarkets[i].Split('~');
int marketID = Convert.ToInt32(marketDetails[0]);
string MarketName = marketDetails[1].ToString();
string MarketStatus = marketDetails[3].ToString();
string EventHeirarchy = marketDetails[6].ToString();
string Menupath = marketDetails[5].ToString();
string[] Arrmenupath = Menupath.Trim(':').Split('\\');
string chieldText = "";
if (indexDepth == 0)
{
if (rootnode == "Cricket" || rootnode == "Tennis" || rootnode == "Golf" || rootnode == "Rugby")
{
if (Arrmenupath[2].Contains("Group") && Arrmenupath[2].Length == 7)
{
if ((indexDepth + 3) <= Arrmenupath.Length - 1)
{
chieldText = Arrmenupath[indexDepth + 3].ToString();
}
}
else
{
if ((indexDepth + 2) <= Arrmenupath.Length - 1)
chieldText = Arrmenupath[indexDepth + 2].ToString();
}
}
else
if ((indexDepth + 2) <= Arrmenupath.Length - 1)
chieldText = Arrmenupath[indexDepth + 2].ToString();
}
else
{
if (Arrmenupath[Arrmenupath.Length - 1] == clickednode.Text)
chieldText = MarketName;
else
{
if (allMarkets[i].Contains(clickednode.Text) && allMarkets[i].Contains(clickednode.Parent.Text) && allMarkets[i].Contains(rootnode))
{
if (rootnode == "Cricket" || rootnode == "Tennis" || rootnode == "Golf" || rootnode == "Rugby")
{
if (Arrmenupath[2].Contains("Group") && Arrmenupath[2].Length == 7)
{
if ((indexDepth + 3) <= Arrmenupath.Length - 1)
{
chieldText = Arrmenupath[indexDepth + 3].ToString();
}
}
else
{
if ((indexDepth + 2) <= Arrmenupath.Length - 1)
chieldText = Arrmenupath[indexDepth + 2].ToString();
}
}
else
if ((indexDepth + 2) <= Arrmenupath.Length - 1)
chieldText = Arrmenupath[indexDepth + 2].ToString();
}
}
}
//check whether node is already added
//if (chieldText.Contains("MiWay"))
//{ }
if (!string.IsNullOrEmpty(chieldText))
{
if (clickednode.Nodes.Count >= 1)
{
bool doesNodeAlreadyExist = false;
foreach (TreeNode node in clickednode.Nodes)
{
if (node.Text == chieldText)
{
doesNodeAlreadyExist = true;
break;
}
}
if (!doesNodeAlreadyExist)
{
clickednode.Nodes.Add(chieldText);
}
}
else
{
clickednode.Nodes.Add(chieldText);
}
}
}
}
clickednode.Expand();
}
我想在 WPF 中使用相同的。请帮助我，或者如果你明白了。
