我有個問題要問。我在我的應用程序中有一個下拉列表。但下拉列表是用層次結構格式填充的。請c中的圖片粗體和下劃線下拉列表菜單項asp.net
如上圖片。我該如何大膽和強調母菜單項，如男,女和不適用另一方面，也不允許父項選擇。
這裏是我的編碼
private void createDDLCategory()
{
ddlCategory.AppendDataBoundItems = true;
ddlCategory.Items.Insert(0, new ListItem("All","A"));
ddlCategory.SelectedIndex = 0;
var ddl1 = dropdownlist.ddlCategoryWithoutGroup();
foreach (var value in ddl1)
{
if (value.P_CATEGORY_ID == null)
{
this.ddlCategory.Items.Add(new ListItem(value.CATEGORY_NAME, value.CATEGORY_ID.ToString()));
this.ddlCategory.Items.FindByValue(value.CATEGORY_ID.ToString()).Selected = false;
this.ddlCategory.Items.FindByValue(value.CATEGORY_ID.ToString()).Attributes.Add("disabled", "true");
this.ddlCategory.Items.FindByValue(value.CATEGORY_ID.ToString()).Attributes.Add("style", "font-weight:bold;");
foreach (var valueChild in ddl1)
{
if (valueChild.P_CATEGORY_ID == value.CATEGORY_ID)
this.ddlCategory.Items.Add(new ListItem(" " + valueChild.CATEGORY_NAME, valueChild.CATEGORY_ID.ToString()));
}
}
}
foreach (ListItem item in ddlCategory.Items)
{
item.Text = HttpUtility.HtmlDecode(item.Text);
}
}
烏爾幫助appreciate.Thanks
