您需要将数据绑定到网格.DataBind();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();
}
}
