问题描述
我正在实现两种形式的功能。在form1中选择任何datagridviewcheckboxcolumn并在单击按钮关闭时显示form2，在form1 datagridviewcheckboxcolumn中将为false？
请帮忙。
命名空间WindowsFormsApplication1
{
公共部分类Form1：表格
{
Form2 Frm2 = new Form2（）;
public Form1（）
{
InitializeComponent（）;
DataGridViewCheckColumn（）;
Frm2.newEvent + = new FrmCheckbox（Frm2_Event）;
}
public void DataGridViewCheckColumn（）
{
dataGridView1.ColumnCount = 6;
dataGridView1.AllowUserToAddRows = false;
DataGridViewCheckBoxColumn colCB = new
DataGridViewCheckBoxColumn（）;
colCB.Name =chkcol;
colCB.HeaderText =选择;
colCB.Width = 40;
dataGridView1.Columns.Add（colCB）;
dataGridView1.Columns [0] .Name =C0;
dataGridView1.Columns [1] .Name =C1;
dataGridView1.Columns [2] .Name =C2;
dataGridView1.Columns [3] .Name =C3;
dataGridView1.Columns [4] .Name =C4;
dataGridView1.Columns [5] .Name =C5;
dataGridView1.Columns [0] .HeaderText =C0;
dataGridView1.Columns [1] .HeaderText =C1;
dataGridView1.Columns [2] .HeaderText =C2;
dataGridView1.Columns [3] .HeaderText =C3;
dataGridView1.Columns [4] .HeaderText =C4;
dataGridView1.Columns [5] .HeaderText =C5;
dataGridView1.Columns [0] .Width = 40;
dataGridView1.Columns [1] .Width = 40;
dataGridView1.Columns [2] .Width = 40;
dataGridView1.Columns [3] .Width = 40;
dataGridView1.Columns [4] .Width = 40;
dataGridView1.Columns [5] .Width = 40;
dataGridView1.Rows.Add（new string [] {A1，B1，C1，
D1，E1 ，F1}）;
dataGridView1.Rows.Add（new string [] {A2，B2，C2，
D2，E2，F2}）;
dataGridView1.Rows.Add（new string [] {A3，B3，C3，
D3，E3，F3}）;
dataGridView1.Rows.Add（new string [] {A4，B4，C4，
D4，E4，F4}）;
dataGridView1.Rows.Add（new string [] {A5，B5，C5，
D5，E5，F5}）;
dataGridView1.Rows.Add（new string [] {A6，B6，C6，
D6，E6，F6}）;
dataGridView1.Rows.Add（new string [] {A7，B7，C7，
D7，E7，F7}）;
dataGridView1.AutoResizeColumns（）;
}
void Frm2_Event（）
{
// for（int i = 0; i< = dataGridView1.Rows.Count - 1 ; i ++）
// {
// if（Convert.ToBoolean（dataGridView1.Rows [i] .Cells
[chkcol]。Value） == true）
// {
// dataGridView1.Rows [i] .Cells [chkcol]。Value = false;
//}
//}
foreach（DataGridViewRow中的dataGridView1.Rows行）
{
if（Convert.ToBoolean（row.Cells [ chkcol]。值）== true）
{
row.Cells [chkcol]。值= false;
}
}
}
private void dataGridView1_CellContentClick（object sender，
DataGridViewCellEventArgs e）
{
for（int i = 0; i< = dataGridView1.RowCount - 1; i ++）
{
if（Convert.ToBoolean（dataGridView1.Rows
[ e.RowIndex] .Cells [chkcol]。Value = true））
{
Frm2.ShowDialog（）;
休息;
}
}
}
}
}
使用System;
使用System.Collections.Generic;使用System.ComponentModel
;
使用System.Data;使用System.Drawing
;
使用System.Linq;
使用System.Text;
使用System.Windows.Forms;
命名空间WindowsFormsApplication1
{
public delegate void FrmCheckbox（）;
公共部分类Form2：表格
{
公共事件FrmCheckbox newEvent;
public Form2（）
{
InitializeComponent（）;
//button1.Click + = new EventHandler（button1_Click）;
}
private void button1_Click（object sender，EventArgs e）
{
if（newEvent！= null）
{
newEvent（ ）;
}
}
}
}
解决方案
I'm implementing a function of two forms. While choosing any of datagridviewcheckboxcolumn in form1 and show form2 when click button to close , in the form1 datagridviewcheckboxcolumn will is false ?
Please help on this.
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
Form2 Frm2 = new Form2();
public Form1()
{
InitializeComponent();
DataGridViewCheckColumn();
Frm2.newEvent += new FrmCheckbox(Frm2_Event);
}
public void DataGridViewCheckColumn()
{
dataGridView1.ColumnCount = 6;
dataGridView1.AllowUserToAddRows = false;
DataGridViewCheckBoxColumn colCB = new
DataGridViewCheckBoxColumn();
colCB.Name = "chkcol";
colCB.HeaderText = "Select";
colCB.Width = 40;
dataGridView1.Columns.Add(colCB);
dataGridView1.Columns[0].Name = "C0";
dataGridView1.Columns[1].Name = "C1";
dataGridView1.Columns[2].Name = "C2";
dataGridView1.Columns[3].Name = "C3";
dataGridView1.Columns[4].Name = "C4";
dataGridView1.Columns[5].Name = "C5";
dataGridView1.Columns[0].HeaderText = "C0";
dataGridView1.Columns[1].HeaderText = "C1";
dataGridView1.Columns[2].HeaderText = "C2";
dataGridView1.Columns[3].HeaderText = "C3";
dataGridView1.Columns[4].HeaderText = "C4";
dataGridView1.Columns[5].HeaderText = "C5";

dataGridView1.Columns[2].Width = 40;
dataGridView1.Columns[3].Width = 40;
dataGridView1.Columns[4].Width = 40;
dataGridView1.Columns[5].Width = 40;
dataGridView1.Rows.Add(new string[] { "A1", "B1", "C1",
"D1", "E1", "F1" });
dataGridView1.Rows.Add(new string[] { "A2", "B2", "C2",

"D6", "E6", "F6" });
dataGridView1.Rows.Add(new string[] { "A7", "B7", "C7",
"D7", "E7", "F7" });
dataGridView1.AutoResizeColumns();
}

// }
//}
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (Convert.ToBoolean(row.Cells["chkcol"].Value) == true)
{
row.Cells["chkcol"].Value = false;
}
}
}
private void dataGridView1_CellContentClick(object sender,
DataGridViewCellEventArgs e)
{
for (int i = 0; i <= dataGridView1.RowCount - 1; i++)
{
if (Convert.ToBoolean(dataGridView1.Rows
[e.RowIndex].Cells["chkcol"].Value = true))
{
Frm2.ShowDialog();
break;
}
}
