How to Perform search functionality in Master-Details of WinForms DataGrid?

In WinForms DataGrid (SfDataGrid), the Master-details view enables searching of data through SearchController.Search method in the GridViewDefinition.DataGrid. Additionally, navigation to the previous and next cells matching the search text is supported using the SearchController.FindPrevious and SearchController.FindNext methods.

SfDataGrid detailsViewGrid;
this.sfDataGrid1.AutoGeneratingRelations += OnAutoGeneratingRelations;

private void OnAutoGeneratingRelations(object sender, AutoGeneratingRelationsEventArgs e)
{
    // To get the DeatilsView dataGrid
    detailsViewGrid = e.GridViewDefinition.DataGrid;
}

private void OnTextChanged(object sender, EventArgs e)
{
    // To perform search in DetailsView DataGrid
    detailsViewGrid.SearchController.Search(this.textBox1.Text);
}

private void previousButtonClick(object sender, EventArgs e)
{
    // To navigate the previous cell match with search text
    if (detailsViewGrid.SearchController.FindPrevious(this.textBox1.Text))
    {
        var detailsViewGrid = sfDataGrid1.GetDetailsViewGrid(this.sfDataGrid1.SearchController.CurrentRowColumnIndex.RowIndex);
        detailsViewGrid.MoveToCurrentCell(detailsViewGrid.SearchController.CurrentRowColumnIndex);
    }            
}

private void nextButtonClick(object sender, EventArgs e)
{
    // To navigate the next cell match with search text
    if (detailsViewGrid.SearchController.FindNext(this.textBox1.Text))
    {
        var detailsViewGrid = sfDataGrid1.GetDetailsViewGrid(this.sfDataGrid1.SearchController.CurrentRowColumnIndex.RowIndex);
        detailsViewGrid.MoveToCurrentCell(detailsViewGrid.SearchController.CurrentRowColumnIndex);
    }
}
