How Can I Customize DataGridView Row Colors Based on Cell Value Comparisons?

DataGridView row color customization

To improve user experience and data clarity, many applications require customizing the appearance of the data grid. A common need is to change the color of a specific row based on a specific data value. This article will explain how to implement this customization in the DataGridView control.

Scene:

Suppose you have a DataGridView and you want to change the color of the row if the value of column 7 is less than the value of column 10. This visual cue helps users quickly identify rows that meet certain criteria.

Solution:

To change the color of a row based on cell value, follow these steps:

1. Iterate over rows: Use a foreach loop to iterate over each row in the DataGridView.
2. Compare cell values: For each row, use the Cells[index] property to retrieve the values ​​for columns 7 and 10. These values ​​are compared to determine whether the condition is met.
3. Set row color: If the condition is true (less than in this case), set the current row's DefaultCellStyle.BackColor property to the desired color, for example Color.Red.

Code example:

<code class="language-csharp">foreach (DataGridViewRow row in vendorsDataGridView.Rows)
{
    if (Convert.ToInt32(row.Cells[7].Value) < Convert.ToInt32(row.Cells[10].Value))
    {
        row.DefaultCellStyle.BackColor = Color.Red;
    }
}</code>

By implementing this method, you can dynamically adjust row colors to highlight specific data patterns and make your DataGridView more informative and visually appealing.
