Get List<TableViewRow>

[JLBLU]

Hi Ahmad,

I want to programmaticaly set a tooltip on some rows.
To do that (ToolTipService.SetToolTip(tvr, toolTip)), I need to loop on TableViewRow collection. How can I get the list of TableViewRow ?
thanks

I would suggest that you should use ContainerContentChanging event of the ListViewBase. You will be able to access TableViewRow along with its content.

Thanks, but it only works halfway. I get each TableViewRow, but I can't assign them a tooltip right away.
Then I tried using ContainerContentChanging only to fetch a list of TableViewRows and then using this list with a Task.Run(() =>
{
...DispatcherQueue.TryEnqueue(
Microsoft.UI.Dispatching.DispatcherQueuePriority.Low ...

But it only works for the first few rows.
It would be nice to have a GetListTableViewRows function in next release.

best regards

not sure how you are trying to set ToolTip to the rows. I tried blow code in SampleApp and it works fine.

<tv:TableView ItemsSource="{Binding Items}" 
              ContainerContentChanging="TableView_ContainerContentChanging" />

private void TableView_ContainerContentChanging(ListViewBase sender, ContainerContentChangingEventArgs args)
{
    if (args.Item is ExampleModel model && args.ItemContainer is TableViewRow row)
    {
        ToolTipService.SetToolTip(row, $"{model.FirstName} {model.LastName}");
    }
}

Oh great thanks.
The issue was that : I tried to retrieve the model from row.Content, and not from args.Item.
Then I had a shift in the display of tooltip.
Now, it works fine !! Thank you very much !!!
best regards
