GridView資料欄條件式變色機制

• 這個欄位放在GridView1的第1個欄位的地方

<asp:TemplateField HeaderText="變色用判斷條件">
	<ItemTemplate>
		<asp:CheckBox ID="IsACheckBox" runat="server" style="display:none" Checked='<%# Eval("IsA") %>' />
		<asp:CheckBox ID="IsBCheckBox" runat="server" style="display:none" Checked='<%# Eval("IsB") %>' />
		<asp:CheckBox ID="IsCCheckBox" runat="server" style="display:none" Checked='<%# Eval("IsC") %>' />
	</ItemTemplate>
</asp:TemplateField>

• 在 GridView1 需使用 RowDataBound 事件處理函數

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
	{
		//TODO: GridView1_RowDataBound
 
		//變色相關
		switch (e.Row.RowType)
		{
			case DataControlRowType.EmptyDataRow:
			case DataControlRowType.Header:
				break;
 
			case DataControlRowType.Footer:
				break;
 
			case DataControlRowType.DataRow:
				{
					TableCellCollection tcDataRow = e.Row.Cells;
 
					//多加變色判斷用欄位, 所以所有的欄位邊號都加1, 最後再移除欄位0
 
 
					//IsA勾選(原欄位2,白底藍字)
					if ((tcDataRow[0].FindControl("IsACheckBox") as CheckBox).Checked == true) 
					{
						Style StyleColor = new Style();
						StyleColor.BackColor = System.Drawing.Color.White;
						StyleColor.ForeColor = System.Drawing.Color.Blue;
						tcDataRow[3].ApplyStyle(StyleColor);
					}
 
 
 
					//IsB勾選(原欄位3,白底紅字)
					if ((tcDataRow[0].FindControl("IsBCheckBox") as CheckBox).Checked == true) 
					{
						Style StyleColor = new Style();
						StyleColor.BackColor = System.Drawing.Color.White;
						StyleColor.ForeColor = System.Drawing.Color.Red;
						StyleColor.CssClass = "NoWrap";
						tcDataRow[4].ApplyStyle(StyleColor);
					}
 
 
					//IsC勾選(原欄位0~10,黃底紅字)
					if ((tcDataRow[0].FindControl("IsCCheckBox") as CheckBox).Checked == true)
					{
						for (int x = 1; x <= 11; x++)
						{
							Style StyleColor = new Style();
							StyleColor.BackColor = System.Drawing.Color.Yellow;
							StyleColor.ForeColor = System.Drawing.Color.Red;
							tcDataRow[x].ApplyStyle(StyleColor);
						}
					}
 
 
					tcDataRow.RemoveAt(0);	//移除顏色判斷用欄位
				}
				break;
 
			//case DataControlRowType.EmptyDataRow:
			//	break;
		}
 
	}
