TextBox中搜索值，因此它发现它在位于GridView中数据 [英] Search value in textBox so it finds it in the data located in gridView

问题描述

有curently我正在打开一个.xls文件，通过在文本框中输入该文件的位置，我想通过在文本框中输入它来搜索某个值，并删除其中的价值所在的行。

Curently i am opening a .xls file, by entering the file location in a text box and i want to search a certain value by entering it in a text box and delete the row in which the value resides in.

下面是code为Form1，包含在DataGridView：

Here is the code for Form1, that contains the dataGridView:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.OleDb;

namespace Plan_de_lucru_1._0
{
    public partial class frPlanMain : Form
    {
        public frPlanMain()
        {
            InitializeComponent();
        }

        private void frPlanMain_Load(object sender, EventArgs e)
        {

        }

        private void GoButton_Click(object sender, EventArgs e)
        {
            string constr = "Provider = MicroSoft.Jet.OLEDB.4.0; Data Source=" + locTBox.Text + "; Extended Properties =\"Excel 8.0; HDR=Yes;\";";
            OleDbConnection con = new OleDbConnection(constr);
            OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [" + shTBox.Text + "$]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            dGVPlan.DataSource = dt;
            new SearchWindow().Show();
            this.Show();
        }
    }
}

这是窗体2包含在其中，我想进入搜索价值的文本框和按钮。

This is Form2 that contains the textBox and button in which i want to enter the search value.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Plan_de_lucru_1._0
{
    public partial class SearchWindow : Form
    {
        public SearchWindow()
        {
            InitializeComponent();
        }

        private void SearchButtonW_Click(object sender, EventArgs e)
        {
            String str = "select * from searchBox where ( Name like '%' + @search + '%')";
            BindingSource bs = new BindingSource();

        }
    }
}

感谢您的帮助。

推荐答案

这为我工作：

namespace Plan_de_lucru_1._0
{
    public partial class SearchWindow : Form
    {
        public frPlanMain refTofrPlanMain;

        public SearchWindow(frPlanMain f) //<<Edit made here 
        {
            refTofrPlanMain = f;
            InitializeComponent();
        }

        private void SearchButtonW_Click(object sender, EventArgs e)
        {
            {
                (refTofrPlanMain.dGVPlan.DataSource as DataTable).DefaultView.RowFilter = string.Format("Vodic = '{0}'", searchTBoxW.Text);
                foreach (DataGridViewRow item in refTofrPlanMain.dGVPlan.Rows)
                {
                    if (item.Visible)
                    {
                        item.Selected = true;
                        break;
