Question

我想用3个文本框过滤DataGridView，我正确地得到了值，但它只适用于第一列（'Surname'），当我输入'Name'或'Phone'时它不会过滤：

protected void btnRic_Click(object sender, EventArgs e)
        {
            if (!string.IsNullOrEmpty(txtSurname.Text) || !string.IsNullOrEmpty(txtName.Text))
            {
                isPhoneNumber = false;
                if (txtCell.Value.Length >= 8)
                {
                    string phoneNumber = txtCell.Value;
                    isPhoneNumber = true;
                }
                DataTable dt = ViewState["dTableGrid"] as DataTable;
                DataView dv = dt.DefaultView;
                if (!isPhoneNumber)
                {
                    dv.RowFilter = string.Format("Surname LIKE '{0}%' OR Surname LIKE '% {0}%' OR Name LIKE ' {1}%' OR Name LIKE '% {1}%'", txtSurname.Text, txtName.Text);
                }
                else
                {
                    dv.RowFilter = string.Format("Surname LIKE ' {0}%' OR Surname LIKE '% {0}%' OR Name LIKE ' {1}%' OR Name LIKE '% {1}%' OR Phone LIKE ' {2}%' OR Phone LIKE '% {2}%'" , txtSurname.Text, txtName.Text, txtCell.Value);
                }
                Grid.DataSource = dv.ToTable();
                Grid.DataBind();

Answer 1

if (!isPhoneNumber)
{
  dv.RowFilter = string.Format("Surname LIKE '{0}%' OR Surname LIKE '%{0}%' OR Name LIKE '{1}%' OR Name LIKE '%{1}%'", txtSurname.Text, txtName.Text);
 }
 else
 {
   dv.RowFilter = string.Format("Surname LIKE '{0}%' OR Surname LIKE '%{0}%' OR Name LIKE '{1}%' OR Name LIKE '%{1}%' OR Phone LIKE '{2}%' OR Phone LIKE '%{2}%'" , txtSurname.Text, txtName.Text, txtCell.Value);
  }

<强>更新检查'% {0}%'之间的空格是否导致问题。
