Question

我有一个现有的datagridview和一个搜索文本框。

当我输入搜索文本并根据以下方法点击搜索按钮（使用存储过程）时，我希望让它自动使用搜索结果重新加载datagridview。

我怎样才能做到这一点？

public static void searchAny(String searchFields, String tblName, String connectionString, SqlCommand tblscmd, SqlDataAdapter tbldataadaptor, DataTable tbldatatable, SqlCommandBuilder cmbuilder, DataGridView DataGridViewName)
{
    using (SqlConnection tblconn = new SqlConnection(connectionString))
    {
        tblconn.Open();
        SqlCommand tblcmd = new SqlCommand();
        tblcmd.Connection = tblconn;
        tblcmd.CommandType = CommandType.StoredProcedure;
        tblcmd.CommandText = "usp_searchany";
        tblcmd.Parameters.Add("@stringToFind", SqlDbType.NVarChar);
        tblcmd.Parameters["@stringToFind"].Value = "%" + searchFields + "%";
        tblcmd.Parameters.Add("@table", SqlDbType.NVarChar);
        tblcmd.Parameters["@table"].Value = tblName;
        cmbuilder.DataAdapter = tbldataadaptor;
        tbldatatable.DefaultView.AllowDelete = true;
        tbldatatable.DefaultView.AllowEdit = true;
        tbldataadaptor.Fill(tbldatatable);
        DataGridViewName.ReadOnly = false;
        DataGridViewName.DataSource = tbldatatable;
        tblconn.Close();
    }
}


private void SearchButton_Click(object sender, EventArgs e)
{
    tbldatatable.Clear();
    String searchFields = SearchTextBox.Text;
    GeneralMethods.searchAny(searchFields, "tblClients", connectionString, tblcmd, tbldataadaptor, tbldatatable, cmbuilder, dataGridView);
    dataGridView.DataSource = tbldatatable;
    dataGridView.Refresh();
}

您必须过滤DataGridView的DataSource ...就像以下方式一样......不需要清除，绑定或刷新datagridview ......

从CellEndEidt开始，这是可能的......

只需过滤DataGridView的DataSource

即可

private void MyDataGrid1_CellEndEdit(object sender, System.Windows.Forms.DataGridViewCellEventArgs e)
{
    if (e.RowIndex == 0)
       {
        if (myDataGrid1.CurrentCell.Value.ToString().Trim().Length > 0)
        {
            MyFilterString="Field1=Feild2 and Field3>Field4";
        }
        MyDtb1.DefaultView.RowFilter = FilterString;
    }
}

搜索并重新加载datagridview
