问题说明
我在gridview中创建列来显示值。
这是我的代码： -
i crate columns in gridview to display values.
this is my code :-
r = dt.NewRow();
r[0] = dt.Rows.Count 1;
r[1] = txt_Job_card.Text;
r[2] = txt_Value_Part.Text;
if (radioButton_Part.Checked == true)
{
r[3] = CB_Auto_parts.Text;
r[5] = x;
}
if (radioButton_repair.Checked == true)
{
r[4] = CB_Repair_type.Text;
}
r[6] = CB_Providers_desc.Text;
r[7] = CB_Hand_installation.Text;
r[8] = txt_Notes.Text;
r[9] = CB_Auto_parts.SelectedValue;
r[10] = CB_Repair_type.SelectedValue;
r[11] = CB_Providers_desc.SelectedValue;
r[12] = CB_Hand_installation.SelectedValue;
dt.Rows.Add(r);
dgv_Add_job_card.DataSource = dt;
ClearText();
txt_Total_Values.Text = (from DataGridViewRow row in dgv_Add_job_card.Rows
where row.Cells[2].FormattedValue.ToString() != string.Empty
select Convert.ToDouble(row.Cells[2].FormattedValue)).Sum().ToString();
}
我的尝试：
i尝试使用此代码，但它不起作用，我有错误，找不到第0列。
What I have tried:
i tried to use this code but its not work and i have error , Cannot find column 0.

我建议使用BindingList并将你的值放在一个类中，这是一个极简主义的例子：
I would recommend using BindingList and putting your values in a class, here is a minimalist example:
using System;
using System.ComponentModel;
using System.Windows.Forms;
namespace TestForm1
{
public partial class Form1 : Form
{
/// <summary>
/// The binding list reference.
/// </summary>
private BindingList<MyClass> masterBindingList;
public Form10()
{
InitializeComponent();
this.Init();
}
private void Init()
{
this.masterBindingList = new BindingList<MyClass>();
this.dataGridViewMaster.DataSource = this.masterBindingList;
}
private void ButtonAddRowClick(object sender, EventArgs e)
{
var rowIndex = this.dataGridViewMaster.RowCount;
this.AddRow(rowIndex);
// this.UpdateRow(rowIndex);
this.ScrollToRow(rowIndex);
}
/// <summary>
/// Add new row via the BindingList.
/// </summary>
private void AddRow(int rowIndex)
{
this.masterBindingList.Add(new MyClass { Title = "Row " rowIndex.ToString() });
}
private void ScrollToRow(int rowIndex)
{
this.dataGridViewMaster.ClearSelection();
this.dataGridViewMaster.FirstDisplayedScrollingRowIndex = rowIndex;
this.dataGridViewMaster.Focus();
}
/// <summary>
/// Simple class with one string.
/// </summary>
public class MyClass
{
public string Title { get; set; }
}
}
