其ID可以直接绑定 ToolTip属性,如
DataTable dt = workLogic.GetPersonID(PersonId); //DataTable dt = new DataTable(); StringBuilder sbName = new StringBuilder(); StringBuilder sbSNO = new StringBuilder(); sbName.Append(dr["USER_CNAME"].ToString().Trim() + ","); this.labelID.text = sbName; this.laeblID.ToolTip = sbSNO ;
myDropDownList.Items[0].Attributes.Add("title", "text").
foreach (ListItem toolTip in <span style="font-weight: bold;">CheckBoxList</span>.Items) { DataRow[] dRows =<span style="font-family: Arial, Helvetica, sans-serif;">CheckBoxListID</span>.Select("USER_CNAME = '" + toolTip.Text.ToString() +"'"); if(dRows != null && dRows.Length>0) { //this.<span style="font-family: Arial, Helvetica, sans-serif;">CheckBoxListID</span>.Items[i].Attributes.Add("",""); this.<span style="font-family: Arial, Helvetica, sans-serif;">CheckBoxListID</span>.Items[0].Attributes.Add("title", dRows[0]["USER_NAME"].ToString()); toolTip.Attributes.Add("title", dRows[0]["USER_NAME"].ToString()); } }
foreach (ListItem item in ckl_EditRole.Items)
{
item.Attributes["title"] = GetRoleTooltip(item.Value);
}
一、DropDownList:
1、选项值保存到数据库:
Hashtable ht=new Hashtable();//这里用Hashtable
ht.Add("字段名",DropDownListID.SelectedItem.Text.ToString());//保存选项Text
ht.Add("字段名",DropDownListID.SelectedItem.Value.ToString());//保存选项Value
2、选项值由数据库绑定到DropDownList:
首先DropDownListID.ClearSelection();//清除选项
DropDownListID.Items.FindByText(dr["字段名"].ToString()).Selected = true;//选项Text
DropDownListID.Items.FindByValue(dr["字段名"].ToString()).Selected = true;//选项Value
二、RadioButtonList:
1、选项值保存到数据库(同DropDownList):
Hashtable ht=new Hashtable();//这里用Hashtable
ht.Add("字段名",RadioButtonListID.SelectedItem.Text.ToString());//保存选项Text
ht.Add("字段名",RadioButtonListID.SelectedItem.Value.ToString());//保存选项Value
2、选项值由数据库绑定到RadioButtonList
string SelectItem = dr["字段名"].ToString();//将数据库中的选项值从DataRow中读出赋给变量SelectItem
for (int i = 0; i < RadioButtonListID.Items.Count; i++)
{//用for循环判断那项被选种
if (RadioButtonListID.Items[i].Text == SelectItem)RadioButtonListID.Items[i].Selected = true;
}
三、CheckBoxList:
1、选项值保存到数据库
string str1= "";//声明一个变量来接受选项
for (int i = 0; i < CheckBoxListID.Items.Count; i++)
{//用for循环将所有选项用","隔开连接起来
if (CheckBoxListID.Items[i].Selected)
{
str1= str1+ CheckBoxListID.Items[i].Value + ",";//选项后加","隔开
}
}
ht.Add("字段名",SelectItem.ToString());
2、选项值由数据库绑定到CheckBoxList
string SelectItem = dr["字段名"].ToString();
string[] arrStr = SelectItem.Split(",");//字段是以","隔开
foreach (string str in arrStr)
{
for (int i = 0; i <CheckBoxListID.Items.Count; i++)
{
if (this.CheckBoxListID.Items[i].Value == str)
{
this.CheckBoxListID.Items[i].Selected = true;
}
}
}
