wpf treeView指定选中项

wpf中指定data对应的treeViewItem为选中项，使用递归

treeView.ItemContainerGenerator.ContainerFromItem(item); treeView这里递归时需替换成子项

 foreach (var item in treeView.Items)

{

var tvi = (TreeViewItem)treeView.ItemContainerGenerator.ContainerFromItem(item);

SetSelect(tvi, data);

}

bool SetSelect(TreeViewItem tvi, PollingGroupModel data)

{

 if (tvi.Items.Count > 0)

{

foreach (var item in tvi.Items)

{

var tviChild = (TreeViewItem)tvi.ItemContainerGenerator.ContainerFromItem(item);

var model = (PollingGroupModel)item;

if (data.DevID == model.DevID && data.ChannelID == model.ChannelID)

{

tviChild.IsSelected = true;

return true;

}

else

{

SetSelect(tviChild, data);

return true;

}

}

}

}
