我的datatable
看起来像这样:
Row1 Row2 Row3 Row4 Row5 Row6
Gold Gold
Pink Pink
#FB7703 #FB7703
Red Red
Yellow
Green
#0B93E1
Purple
如何将gridview中单元格的背景颜色设置为单元格中的颜色?
我知道我需要使用RowDataBound
。
gridview的标记:
<div>
<asp:GridView ID="GridViewClicks" runat="server"
onrowdatabound="GridViewClicks_RowDataBound">
</asp:GridView>
</div>
填充数据表的代码隐藏:
DataTable dataTable = GetColors();
DataTable gridTable = new DataTable();
gridTable.Columns.Add("Row1", typeof(string));
gridTable.Columns.Add("Row2", typeof(string));
gridTable.Columns.Add("Row3", typeof(string));
gridTable.Columns.Add("Row4", typeof(string));
gridTable.Columns.Add("Row5", typeof(string));
gridTable.Columns.Add("Row6", typeof(string));
for (int i = 0; i < 8; i++)
{
var r = gridTable.NewRow();
gridTable.Rows.Add(r);
}
foreach (DataRow r in dataTable.Rows)
{
int rowNum = Convert.ToInt16(r[1]) - 1;
int colNum = Convert.ToInt16(r[3]);
gridTable.Rows[rowNum][colNum] = r["color"].ToString();
}
GridViewClicks.DataSource = gridTable;
GridViewClicks.DataBind();
感谢。

您可以检查RowDataBound
事件中每个单元格的值,并根据单元格的值为单元格着色。
protected void GridViewClicks_RowDataBound(object sender, GridViewRowEventArgs e)
{
//check if the current row is a datarow
if (e.Row.RowType == DataControlRowType.DataRow)
{
//loop all the cells in the row
foreach (TableCell cell in e.Row.Cells)
{
//check if the color is hex or a string
if (cell.Text.Contains("#"))
{
cell.BackColor = ColorTranslator.FromHtml(cell.Text);
}
else
{
cell.BackColor = Color.FromName(cell.Text);
}
}
}
}
