DataGridView cell text and cell value
提问by C??ngTV
I have a problem with a readonly C# Winform DataGridView.
我有一个只读 C# Winform DataGridView 的问题。
I have a DataSourcefor a DataTableand assign it to DataGridView1.DataSource. I want to display cell text by cell value without changing the DataSource.
我有一个DataSourcefor aDataTable并将其分配给DataGridView1.DataSource. 我想按单元格值显示单元格文本而不更改DataSource.
Ex:
前任：
cell value=1 => cell display text="one",
cell value=2 => cell display text="two"
I want that, if I get:
我想要那个，如果我得到：
DataGridView1.Rows[rowIndex].Cells[columnIndex].Value
Then it must be 1(or 2, or 3) not "one" (or "two", or "three").
那么它必须是1（或2，或3）不是“一”（或“二”，或“三”）。

You can use CellFormatting event handler.
您可以使用 CellFormatting 事件处理程序。
private void DataGridView1_CellFormatting(object sender,
DataGridViewCellFormattingEventArgs e)
{
DataGridView dgv = (DataGridView)sender;
if (dgv.Columns[e.ColumnIndex].Name == "TargetColumnName" &&
e.RowIndex >= 0 &&
dgv["TargetColumnName", e.RowIndex].Value is int)
{
switch ((int)dgv["TargetColumnName", e.RowIndex].Value)
{
case 1:
e.Value = "one";
e.FormattingApplied = true;
break;
case 2:
e.Value = "two";
e.FormattingApplied = true;
break;
}
}
}

my solutions is to put the value in DataGridViewCell.Tag property.
我的解决方案是将值放在 DataGridViewCell.Tag 属性中。
Like this :
像这样 ：
DataGridView1.Rows[rowIndex].Cells[columnIndex].Tag = 1;

you can create class for it:
你可以为它创建类：
public class Item
{
public int Id { get; }
public string Name { get; }
public Item(string name, int id)
{
Id = id;
Name = name;
}
public override string ToString()
{
return Name;
}
}
Then
然后
DataGridView1.Rows[rowIndex].Cells[columnIndex]=new Item("One", 1);
