如何根据条件

推荐答案

更改gridview中的特定单元格颜色.1。对于ASP.NET项目，在网格视图中 RowDataBound 事件你可以像下一个例子那样做：

1.In the case of ASP.NET projects, in the grid view's RowDataBound event you could do it like in the next example:

protected void _yourGridView_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.Cells[0].Text == "someValue") //Here is the condition!
                {
                    //   
                    //Change the cell color.
                    e.Row.Cells[0].ForeColor = System.Drawing.Color.Red;
                    //
                    //Change the back color.
                    e.Row.Cells[0].BackColor = Color.Yellow;
                    
                }
            }
        }

2.对于Windows窗体，你应该使用DataGridView对象，并且使用 DataBindingComplete 事件更改您必须执行的颜色，如下例所示：

2.In the case of Windows Forms you should use DataGridView objects, and to change the colors you have to do it by using DataBindingComplete event like in the next example:

private void _yourDataGridView_DataBindingComplete(object sender,
    DataGridViewBindingCompleteEventArgs e)
{
 //...
 //
if(condition) //Your condition!
{
_yourDataGridView.Item(0, 1).Style.ForeColor = Color.Red;
_yourDataGridView.Item(0, 1).Style.BackColor = Color.Yellow;
}
}

你可以使用gridview RawDataBound事件做这件事

you can do this stuff using gridview RawDataBound event

protected void grdDoc _RowDataBound(object sender, GridViewRowEventArgs e)
{
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if ((string.IsNullOrEmpty(e.Row.Cells[3].Text) != true)
                  || (e.Row.Cells[3].Text != " "))
            {
                string result = Convert.ToInt32(e.Row.Cells[2].Text);
                if (result == "M.S")
                    e.Row.Cells[3].BackColor= System.Drawing.Color. Aquamarine;
                else
                    e.Row.Cells[3].BackColor= System.Drawing.Color. BlanchedAlmond;
            }
        }
    }
}

我通常使用CellFormatting事件。每次在Datagrid中显示一行时都会触发它。你有一个例子这里 [ ^ ]

I normally use the CellFormatting event. It's fired everytime a row is showed in the Datagrid. You've got an example here[^]
