title: Blazor - change value in child component but get it to update the parent interface to
body: <p>I have a Blazor Server app, I have a Blazor page which has some tabs in the tab heading I show the count of rows in the Grid, eg Tab1Name (RowCount), Tab2Name (RowCount), Tab3Name (RowCount)</p>
  <p>I have created a Grid component that shows the data.  This data is passed down as [Parameter] from my Page.  In that grid, the user can edit the data, eg add/edit/delete records.  This could change the count that appeared in the Tab heading.  So I want to refresh this count.</p>
  <p>Any idea how I could refresh the RowCount in the tab heading?</p>
  <p>Can I some how force the child control to refresh the parent page, without doing a full page reload?</p>
  <p>TIA</p>
