i具有一个动态生成的GridView，其中列数量未知。单元格中的数据为1和0（矩阵类型值）。有没有一种方法可以使绿色1s和0s为白色的细胞上色？
asp.net中的代码：

这是我表的示例：
具有1NS的细胞 - 应为绿色具有0s的单元格 - 应为白色
______________________________________
COLUMNS n1 n2 n3 n4 n5 n6 ... n
VALUE1 1 0 1 0 0 1 ... 0
VALUE2 0 0 1 0 1 1 ... 1
VALUE3 0 1 1 0 0 1 ... 1
VALUE4 1 1 1 0 0 1 ... 0
..... . . . . . . ... .
VALUEn 1 0 1 1 0 1 ... 0

您可以为此使用OnRowdDataBound事件。如果您不知道数据集中的列数量，则必须循环每个单元格并检查其值。
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//check if the rowtype is a datarow
if (e.Row.RowType == DataControlRowType.DataRow)
{
string lastLetter = string.Empty;
//check if cell 1 actually contains data, otherwise substring will fail
if (!string.IsNullOrEmpty(e.Row.Cells[0].Text))
{
//get the last letter of the string in cell 1
lastLetter = e.Row.Cells[0].Text.Substring(e.Row.Cells[0].Text.Length - 1, 1).ToUpper();
}
//loop all the cells in the row
for (int i = 0; i < e.Row.Cells.Count; i++)
{
int value = 0;
//try converting the cell value to an int
try
{
value = Convert.ToInt32(e.Row.Cells[i].Text);
}
catch
{
}
//check the value and set the background color
if (value == 1 && lastLetter == "H")
{
e.Row.Cells[i].BackColor = Color.Green;
}
else if (value == 1 && lastLetter == "N")
{
e.Row.Cells[i].BackColor = Color.Blue;
}
else
{
e.Row.Cells[i].BackColor = Color.White;
}
}
}
}
在rowdatabound事件上，尝试。
{
if (DataBinder.Eval(e.Row.DataItem, "n1") == 0)
{
e.Row.Cells[1].BackColor = System.Drawing.Color.Green;
}
else
{
e.Row.Cells[1].BackColor = System.Drawing.Color.White;
}
}
