How Can I Programmatically Add Rows to a DataGridView?

Programmatically Adding Rows to a DataGridView

Several methods exist for adding new rows to a DataGridView control. Let's explore the most common approaches.

Method 1: Cloning an Existing Row

This approach creates a new row by duplicating an existing one, preserving the column structure.

<code class="language-csharp">DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);</code>

This ensures consistency in the new row's column layout.

Method 2: Utilizing Column Names

This offers more precise control by specifying column names directly.

<code class="language-csharp">DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);</code>

This method is particularly useful when dealing with a large number of columns.

Method 3: Direct Row Value Addition

This allows for adding multiple rows simultaneously, supplying values for each column as parameters.

<code class="language-csharp">this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");</code>

Rows.Add appends rows, while Rows.Insert inserts at a specific index. This is efficient for bulk row additions.
