Two different formats in the datagridview column

问题

I have a column called Discount Value in DataGridView which has two different formats namely Currency and Percentage.

Is it possible to do a different format on one column of the DataGridView? Thanks.

I tried using the code below but the output is not as expected. Problem in RegulerDiscount_DataGridView_CellFormatting

	namespace WinFormsApp1
	{
		public partial class Form1 : Form
		{
			public Form1()
			{
				InitializeComponent();

				List<RegulerDiscountModel> regulerDiscountModelList = new List<RegulerDiscountModel>();

				RegulerDiscountModel regulerDiscountModel1 = new RegulerDiscountModel();
				regulerDiscountModel1.RegulerDiscountID = 1;
				regulerDiscountModel1.RegulerDiscountProductId = 1;
				regulerDiscountModel1.RegulerDiscountProductName = "Product 1";
				regulerDiscountModel1.RegulerDiscountName = "Disc1";
				regulerDiscountModel1.RegulerDiscountValue = 1000;
				regulerDiscountModel1.RegulerDiscountStrTypeId = "Rp";
				regulerDiscountModelList.Add(regulerDiscountModel1);

				RegulerDiscountModel regulerDiscountModel2 = new RegulerDiscountModel();
				regulerDiscountModel2.RegulerDiscountID = 1;
				regulerDiscountModel2.RegulerDiscountProductId = 1;
				regulerDiscountModel2.RegulerDiscountProductName = "Product 1";
				regulerDiscountModel2.RegulerDiscountName = "Disc2";
				regulerDiscountModel2.RegulerDiscountValue = 2000;
				regulerDiscountModel2.RegulerDiscountStrTypeId = "Rp";
				regulerDiscountModelList.Add(regulerDiscountModel2);

				RegulerDiscountModel regulerDiscountModel3 = new RegulerDiscountModel();
				regulerDiscountModel3.RegulerDiscountID = 1;
				regulerDiscountModel3.RegulerDiscountProductId = 1;
				regulerDiscountModel3.RegulerDiscountProductName = "Product 1";
				regulerDiscountModel3.RegulerDiscountName = "Disc3";
				regulerDiscountModel3.RegulerDiscountValue = 10.5;
				regulerDiscountModel3.RegulerDiscountStrTypeId = "%";
				regulerDiscountModelList.Add(regulerDiscountModel3);

				RegulerDiscountModel regulerDiscountModel4 = new RegulerDiscountModel();
				regulerDiscountModel4.RegulerDiscountID = 1;
				regulerDiscountModel4.RegulerDiscountProductId = 1;
				regulerDiscountModel4.RegulerDiscountProductName = "Product 1";
				regulerDiscountModel4.RegulerDiscountName = "Disc4";
				regulerDiscountModel4.RegulerDiscountValue = 20.1;
				regulerDiscountModel4.RegulerDiscountStrTypeId = "%";
				regulerDiscountModelList.Add(regulerDiscountModel4);

				CtechGroupedDataGridView.DataSource = regulerDiscountModelList;
				CtechGroupedDataGridView.CellFormatting += CtechGroupedDataGridView_CellFormatting;
			}

			private void CtechGroupedDataGridView_CellFormatting(object? sender, DataGridViewCellFormattingEventArgs e)
			{
				try
				{
					if (e.RowIndex >= 0 && e.RowIndex <= CtechGroupedDataGridView.Rows.Count - 1)
					{
						DataGridViewRow row = CtechGroupedDataGridView.CurrentRow;
						if (row != null)
						{
							// ID ProductId ProductName DiscountName DiscountValue DiscountType
							// 0  1         2           3            4             5

							if (row.Cells[4].Value != null && row.Cells[5].Value != null)
							{
								String? strDiscountValue = row.Cells[4].Value.ToString();
								String? strDiscountType = row.Cells[5].Value.ToString();
								if (!String.IsNullOrEmpty(strDiscountValue) && !String.IsNullOrEmpty(strDiscountType))
								{
									switch (strDiscountType)
									{
										case "Rp":
											CtechGroupedDataGridView[4, e.RowIndex].Style.Format = "N0";
											break;

										case "%":
											CtechGroupedDataGridView[4, e.RowIndex].Style.Format = "P1";
											break;
									}
								}
							}
						}
					}
				}
				catch (Exception ex)
				{
					MessageBox.Show(ex.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
				}
			}
		}
	}

Current Output:
Two different formats in the datagridview column

When I clicked on DataGridView, I get Output as follows:

以下是您提供的代码的翻译部分：

```csharp
private void CtechGroupedDataGridView_CellFormatting(object? sender, DataGridViewCellFormattingEventArgs e)
{
    try
    {
        if (e.RowIndex >= 0 && e.RowIndex <= CtechGroupedDataGridView.Rows.Count - 1)
        {
            // 这里有一个错误
            //DataGridViewRow row = CtechGroupedDataGridView.CurrentRow;
            DataGridViewRow row = CtechGroupedDataGridView[e.ColumnIndex, e.RowIndex].OwningRow;

            if (row != null)
            {
                // ID ProductId ProductName DiscountName DiscountValue DiscountType
                // 0  1         2           3            4             5

                if (row.Cells[4].Value != null && row.Cells[5].Value != null)
                {
                    String? strDiscountValue = row.Cells[4].Value.ToString();
                    String? strDiscountType = row.Cells[5].Value.ToString();
                    if (!String.IsNullOrEmpty(strDiscountValue) && !String.IsNullOrEmpty(strDiscountType))
                    {
                        switch (strDiscountType)
                        {
                            case "Rp":
                                CtechGroupedDataGridView[4, e.RowIndex].Style.Format = "N0";

                                break;
                        }
                    }
                }
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

希望这有助于您理解代码的翻译。

英文: 
private void CtechGroupedDataGridView_CellFormatting(object? sender, DataGridViewCellFormattingEventArgs e)
{
try
{
if (e.RowIndex &gt;= 0 &amp;&amp; e.RowIndex &lt;= CtechGroupedDataGridView.Rows.Count - 1)
{
// Bug in here
//DataGridViewRow row = CtechGroupedDataGridView.CurrentRow;
DataGridViewRow row = CtechGroupedDataGridView[e.ColumnIndex, e.RowIndex].OwningRow;
if (row != null)
{
// ID ProductId ProductName DiscountName DiscountValue DiscountType
// 0  1         2           3            4             5
if (row.Cells[4].Value != null &amp;&amp; row.Cells[5].Value != null)
{
String? strDiscountValue = row.Cells[4].Value.ToString();
String? strDiscountType = row.Cells[5].Value.ToString();
if (!String.IsNullOrEmpty(strDiscountValue) &amp;&amp; !String.IsNullOrEmpty(strDiscountType))
{
switch (strDiscountType)
{
case &quot;Rp&quot;:
CtechGroupedDataGridView[4, e.RowIndex].Style.Format = &quot;N0&quot;;
break;
case &quot;%&quot;:
// Bug in here
//CtechGroupedDataGridView[4, e.RowIndex].Style.Format = &quot;P1&quot;;
CtechGroupedDataGridView[4, e.RowIndex].Style.Format = &quot;F1&quot;;
break;
}
}
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString(), &quot;Error&quot;, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

Output

Two different formats in the datagridview column
