Paging index does not display when rebinding to search results

C#

The paging index is not displayed when rebinding to search results making it impossible for user to see all the search results in the rest of the pages.

What I have tried:

Below is the code i use to load data when it has been filtered

private void BindGrid(string searchTerm = "")
{
    var data = GetData();
    int totalEntries = data.Count;

    if (!string.IsNullOrWhiteSpace(searchTerm))
    {
        data = data.Where(d => d.GetType().GetProperties()
            .Any(prop => prop.GetValue(d, null)?.ToString().IndexOf(searchTerm, StringComparison.OrdinalIgnoreCase) >= 0)).ToList();
    }

    int filteredEntries = data.Count;
    int entriesPerPage = GridView1.PageSize;

    GridView1.AllowPaging = true;

    // Adjust PageIndex if it exceeds the number of available pages
    int totalPages = (int)Math.Ceiling((double)filteredEntries / entriesPerPage);
    if (GridView1.PageIndex >= totalPages)
    {
        GridView1.PageIndex = totalPages - 1; // Set to last page if current exceeds total
    }

    // Ensure PageIndex is reset if no results are found
    if (filteredEntries == 0)
    {
        GridView1.PageIndex = 0;
    }

    GridView1.DataSource = data.Skip(GridView1.PageIndex * entriesPerPage).Take(entriesPerPage).ToList();
    GridView1.DataBind();

    LabelEntryCount.Text = $"Showing {GridView1.Rows.Count} of {filteredEntries} entries";

    GridView1.Visible = filteredEntries > 0;
    GridView1.PagerSettings.Visible = filteredEntries > entriesPerPage;
}

The below is what i use to load data when its not filtered

private void BindGrid()
{
    var data = GetData();
    int totalEntries = data.Count;

    GridView1.DataSource = GetData();
    GridView1.DataBind();

    int currentPageEntries = GridView1.Rows.Count;
    LabelEntryCount.Text = "Showing " + currentPageEntries + " of " + totalEntries + " entries";

}
