您需要将数据绑定到网格.DataBind();上以刷新它。

protected void FilterButton_Click(object sender, EventArgs e)

{
    if (string.IsNullOrEmpty(this.FilterTextBox.Text))
    {
        this.GridView1.DataSource = db.Yetenekler.Local.ToBindingList();
        this.GridView1.DataBind();
    }
    else
    {
        var filteredData = db.Yetenekler.Local
                             .Where(x => x.adi.Contains(this.FilterTextBox.Text));
        this.GridView1.DataSource = filteredData.ToList();
        this.GridView1.DataBind();
    }
}
