Add rows to DataGridView programmatically

Adding rows to a DataTable is simple, just use the NewRow and Add methods. So, how to achieve the same operation in DataGridView?

Create new row

To add a new row to the DataGridView, you can clone the existing row's structure and assign values ​​to its cells individually.

Method 1

<code class="language-c#">DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "单元格1的值";
row.Cells[1].Value = "单元格2的值";
yourDataGridView.Rows.Add(row);</code>

Method 2

If you know the column names, you can reference them directly in the clone.

<code class="language-c#">DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column1"].Value = "单元格1的值";
row.Cells["Column2"].Value = "单元格2的值";
yourDataGridView.Rows.Add(row);</code>

Other methods

Add method

Use the Add method to specify values ​​directly in parameters.

<code class="language-c#">this.dataGridView1.Rows.Add("Column1 Value", "Column2 Value", "Column3 Value");</code>

Insert method

The Insert method allows you to add a row at a specific index.

<code class="language-c#">this.dataGridView1.Rows.Insert(0, "Value1", "Value2", "Value3");</code>
