我有一个下拉式cboVendor,其中供应商名称正在其中
我希望背景颜色为红色,其fullyAgg
列(dt contains 11 columns in which fullagg is the 11th column
)即将为零。当前我正在执行以下代码所示的操作,但它将所有这些都设为零(这不应该发生)
.aspx
<asp:DropDownList ID="cboVendor" runat="server" AppendDataBoundItems="True"
AutoPostBack="true"> <asp:ListItem Value="0">- Select Vendor -</asp:ListItem>
</asp:DropDownList>
C#代码
DataTable dt = default(DataTable);
cboVendor.DataSource = dt;
cboVendor.DataTextField = "SupplierName";
cboVendor.DataValueField = "SupplierID";
cboVendor.DataBind();
cboVendor.SelectedIndex = 0;
foreach (ListItem item in cboVendor.Items) {
if (dt.Rows(10)("fullyAgg") == 0) {
item.Attributes.Add("style", "background-color:red;");
}
}
最佳答案
找到了解决方案
DataView dv = dt.DefaultView;
dv.RowFilter = "fullyAgg=0";
foreach (DataRowView dr in dv) {
foreach (ListItem item in cboVendor.Items) {
if (dr("SupplierID").ToString() == item.Value.ToString()) {
item.Attributes.Add("style", "background-color:red;");
}
}
}
