问题描述
大家好,
我需要一些帮助来构建vb.net服务器端的下拉列表。
我发现我可以从
Hi Everyone,
I am in need of some help with constructing a drop down list within vb.net server side.
I have found i can start with something like
Dim dl As New DropDownList
但我仍然坚持如何继续,我在网上寻求帮助,但这看起来很混乱。
我需要使用存储过程中的数据填充DropDownList
如果您需要更多代码或信息请询问
谢谢
我尝试使用以下代码填写DDL但是没有填充
but iam stuck as of how to continue, i have search online for help but it all looks confusing.
I need to populate the DropDownList with data from a stored procedure
if you need anymore code or info please ask
Thank you
I have tried filling in the DDL in with the following code but nothing is populated
If Request.QueryString("userid") <> "" Then
Dim ddlResult As New DataSet
ddlResult = GetUserName.ddlData(Request.QueryString("userid").ToString)
sysDDL.DataSource = ddlResult
sysDDL.DataValueField = "description"
sysDDL.DataTextField = "description"
sysDDL.DataBind()
sysDDL.Items.Insert(0, New ListItem(String.Empty, String.Empty))
sysDDL.SelectedIndex = 0
End If
新密码...
包含DIV DDL
New Code...
DIV containing DDL
<div id="dUserSystems" runat="server" >
<u>Systems user has access to</u><br />
<div id="dUserData"></div>
<br />
<div id="ddlSysData" runat="server" >
<u>Add new system to users account</u><br />
<asp:DropDownList ID="sysDDL" runat="server"/>
</div>
<br />
<input type="button" id="butAdd" value="Add" runat="server"/>
<input type="button" onclick="butClose()" value="Close" />
</div>
我的函数从隐藏页面调用数据来为'dUserData'创建一个表,我想我可能需要在这里添加一些东西让DDL工作?
My function that calls data from a stealth page to create a table for 'dUserData' and i think i may need to add something in here for the DDL to work?
function viewSystems(myUserid) {
var link = 'fetchData.aspx?userid=' + myUserid;
$.get(link, function (data) {
$("#dUserData").empty().append(data);
$("#ContentPlaceHolder1_dUserSystems").css("left", "200px");
$("#ContentPlaceHolder1_dUserSystems").css("display", "block");
});
}
function butClose() {
$("#ContentPlaceHolder1_dUserSystems").css("display", "none");
}
推荐答案
.get(link, function (data){
.get(link, function (data) {
( #dUserData)。empty()。append(data);
("#dUserData").empty().append(data);
( # ContentPlaceHolder1_dUserSystems)。css( left, 200px);
("#ContentPlaceHolder1_dUserSystems").css("left", "200px");
