[英]Changing text color of specific column based on value of cell in datagridview
[英]Changing Row Color of DataGridView Based on Cell Value
我有兩列即文件名和狀態的 Data Gridview DataGridview有這樣的數據源設置
var bs = new BindingSourceAsync();
bs.DataSource = data;
dataGridView4.DataSource = bs;
使用async-await方法更新“狀態列”的值。當“狀態值”為“無效”時,如果其“有效”,我需要將相應的行顏色更改為紅色和綠色。
為此,我嘗試掛鈎到DataGridView的CellValueChanged事件
dataGridView4.CellValueChanged += DataGridView4_CellValueChanged;
但是該事件從未觸發過。我該如何解決此問題。請提出建議。
是的,在RowDataBound中獲取gridview
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
// check if it is the DataRow not the header row
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Cell[1] is the cell contain the value for the condition
if (Convert.ToInt16(e.Row.Cells[1].Text) < 10)
{
e.Row.Cells[0].BackColor = System.Drawing.Color.Yellow;
e.Row.Cells[1].BackColor = System.Drawing.Color.Yellow;
}
else if (Convert.ToInt16(e.Row.Cells[1].Text) < 30)
{
e.Row.Cells[0].BackColor = System.Drawing.Color.Blue;
e.Row.Cells[1].BackColor = System.Drawing.Color.Blue;
}
}
}
