Question

在Windows应用程序中，我有一个Datagridview和Textbox控件。我正在使用存储过程在datagridview中显示一些数据。问题是，当我尝试在datagridview中搜索时，什么也没发生，而且输入到文本框时也很漫长，我发现了

CustomersList.DataSource = dt;

是原因。我对使用存储过程很陌生。我希望有人能够帮助我。

这是用于搜索的代码

Datatable dt;
private void txt_usersearch_TextChanged(object sender, EventArgs e)
{
    using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["SalesInventoryManagement.Properties.Settings.Setting"].ConnectionString))
        {
            using (var cmd = new SqlCommand("usp_GetCustomers", con))
            {
                cmd.CommandType = CommandType.StoredProcedure;                   
                dt.DefaultView.RowFilter = "Full_Name LIKE '%{txt_usersearch.Text}%'";
                CustomersList.DataSource = dt;
            }
        }
}

这段代码是将我的数据显示到datagridview

public class Display 
{
    public static void Display_Customer(DataTable dt, DataGridView dgv)
    {     
        using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["SalesInventoryManagement.Properties.Settings.Setting"].ConnectionString))
        {
            using (var cmd = new SqlCommand("usp_GetCustomers", con))
            {               
                con.Open();
                cmd.CommandType = CommandType.StoredProcedure;

                using (var sda = new SqlDataAdapter(cmd))
                {                        
                    dt = new DataTable();
                    sda.Fill(dt);
                    dgv.DataSource = dt;
                }

                con.Close();
            }
        }
    }  
}

表格加载

private void ManageCustomer_Load(object sender, EventArgs e)
{
        Display.Display_Customer(dt, CustomersList);
}

为什么要使用“文本更改”事件。那不是一个好方法。我曾经在Dgv EdiitingControl事件上进行实时搜索。您应该在Dgv上进行实时搜索，然后向我展示您编写的存储过程

private void dgv_sales_EditingControlShowing(object sender, 
    DataGridViewEditingControlShowingEventArgs e)
        {
        try
        {
            if (dgv_sales.CurrentCell.ColumnIndex==0)
            {
                TextBox prodname = e.Control as TextBox;
                if (prodname!=null)
                {
                    prodname.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                    prodname.AutoCompleteCustomSource = ClientListDropDown();
                    prodname.AutoCompleteSource = AutoCompleteSource.CustomSource;
                }
            }
            else if (dgv_sales.CurrentCell.ColumnIndex==7)
            {
                TextBox prodname = e.Control as TextBox;
                if (prodname != null)
                {
                    prodname.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                    prodname.AutoCompleteCustomSource = BatchNoDropDown();
                    prodname.AutoCompleteSource = AutoCompleteSource.CustomSource;
                }

            }
            else
            {
                TextBox prodname = e.Control as TextBox;
                if (prodname != null)
                {
                    prodname.AutoCompleteMode = AutoCompleteMode.None;

                }

            }

        }
        catch (Exception)
        {


        }
    }

解决了：）

DataView dv = dt.DefaultView;
dv.RowFilter = string.Format("Full_Name like '%{0}%'", txt_usersearch.Text);
CustomersList.DataSource = dv.ToTable();
