I have a drop downlist on server with a list of groups from the logged in user. When the user select a group from the drop down list I have to add a "Remove" link next to this drop down list and anohter link "Add to another group" down to this drop down list. If the clicks on this link then another drop down list with the groups except the one user selected in the above drop down list should be created on top of it. Does any one please tell me, how to do this and I have a sample image of my explanation in this link:
http://www.doxtop.com/Browse/3645e617/addtomultiplegroups.aspx?private_key=fca98fbb
Here is my code: I could add new drop down list on clicking the "Add another group" link but I need to get the items in the new drop downlist as items- the previous selected item.
<tr id="trGroups" style="display: none;">
<td class="tdUpload10">Groups:</td>
<td id="tdGroups"> <asp:DropDownList ID="ddlGroups" runat="server" CssClass="dropdown1" Width="50%">
</asp:DropDownList> <a href="" id="lRemovePub" runat="server" class="link1" style="display:none;vertical-align:top">Remove </a>
<div id="divDDLMore" style="display:none;vertical-align:top">
</div> <div id="div1" runat="server" style="display:none"> Attached successfully. <a href="" id="A3" runat="server" class="link1">Remove </a></div> </td> </tr>
<tr id="trMoreGroups" style="display:none;vertical-align:top" runat="server">
<td> </td> <td>
<a href="" id="lMoreGroup" runat="server" class="link1" onclick="AddToMoreGroups()">Add to another group</a> </td> </tr>
Here is my javascript code:
function AddToMoreGroups()
{
var tdGroups = document.getElementById(tdGroups);
var ddlGroupId = document.getElementById(ddlGroupsId);
var trMoreGroups = document.getElementById(trMoreGroupsId);
var ddlGroups = '';
ddlGroups += '<select class=\"dropdown1\" style=\"width:50%\" id=\"ddlGroups\" runat=\"server\">';
var groupsArray = allGroups.split(';');
if(groupsArray != '')
{
ddlGroups += "<option value = '" +emptyGroup +"'>Select Group...</option>"
for(var i =0; i <groupsArray.length; i++)
{
var grArr = groupsArray[i].split(',');
ddlGroups += "<option value='"+ grArr[0] +"'>" +grArr[1]+"</option>"
}
}
ddlGroups += "</select> <a runat=\"server\" class=\"link1\" style=\"display:none;vertical-align:top\">Remove </a> <br/>"
divDDLMore.innerHTML += ddlGroups;
divDDLMore.style.display = '';
trMoreGroups.style.display = 'none';
}
function SetAudience()
{
var ddlGroupId = document.getElementById(ddlGroupsId);
var trMoreGroups = document.getElementById(trMoreGroupsId);
var lRemovePub = document.getElementById(lRemovePubId);
// Get Selected Value
var GroupId = '00000000-0000-0000-0000-000000000000';
if(ddlGroupId != null)
{
for(var i=0; i < ddlGroupId.options.length; i++)
{
if(ddlGroupId.options[i].selected == true)
{
GroupId = ddlGroupId.options[i].value;
if(GroupId != '00000000-0000-0000-0000-000000000000')
{
trMoreGroups.style.display = '';
lRemovePub.style.display = '';
}
break;
}
}
}
}
Any Ideas please!!!

If you're adding them on the client, they won't appear in viewstate, but they will appear in the form that gets posted back to the server.

As you can see in my code I could store the selected groupIds in a variable and add the items by checking these groupIds.
I have another problem here. I created my other drop down lists on client side using javascript and all the html code for the to a but on the JS side if i want to get the items I am popping up with the javascript error.
Here the first line is breaking. Can't get the items of my drop down list created on client side.
for(var i=0; i < ddlGroups.options.length; i++)
{
if(ddlGroups.options[i].selected == true)
{
grId = ddlGroups.options[i].value;
break;
}
}

1 - put the datalist in the master page, what's the issue ?
2 - use target="_blank" to open a new page
Hard to say why you have an exception without seeing the code. Haven't you been asking this all day ?

Why are you using Master Page ?
Do you need to display datalist in each page ?
If yes do one thing instead of putting directly in Master Page
Put the DataList in the ASP.Panel and give it height and width.
You can't put the datalist directly in Contentplaceholder
Thanks and Regards

Just remove the ContentPlaceHolder and have your datalist in the Panel
give proper height and width to your Panel
I don't understand why you are using Master Page ?
you should explain the necessity of using the master Page as it is common for all pages to show common Layout
Thanks and Regards

If you are using Masterpage to display it in every page you should you use a common methods class instead. You can put your datalist in there and then call it from each page.
A masterpage is generally used to create a global layout for your application.

Masterpage is generally used to create a layout for your website.
To create a common methods class just add a new class to your project in the app_code folder and add in your datalist code. Then you just write the name of the class followed by the function name and that will call it from your desired page.

Having got a 1 for giving a useful answer, I feel compelled to ask what the hell you're doing struggling with this if you're a 'new user of ASP.NET'. Have you bought some books and worked through them ? Read some articles ? Or is someone paying you to bumble through this with our help ?

You asked, asked again while your question is visible, ( which is very rude ) and then give me a 1 vote for trying to help. So, screw you, and your 'thanks'.
I assume this means I am right, you've bought no books, done no research and you're blindly flailing by asking poorly worded questions over and over. Good luck with that.

This is the code. how do i fix it??
Public Function getData(ByVal strSplzCD As String, ByVal strSplzName As String) As clsHrmSplzAreasInfo()
Dim cnn As clsConn
Dim ds As DataSet
Dim dt As DataTable
Dim al As New ArrayList
Dim row As DataRow
Dim arr As Array
Dim str As String
Try
cnn = New clsConn
str = "Select * from HRM_SPLZ_AREAS "
ds = cnn.GetData(str)
dt = ds.Tables(0)
For Each row In dt.Rows
Dim objSplz As New clsHrmSplzAreasInfo
objSplz.SPLZCD = IIf(IsDBNull(row("SPLZ_CD")), "", row("SPLZ_CD")).ToString()
objSplz.SPLZNAME = IIf(IsDBNull(row("SPLZ_NAME")), "", row("SPLZ_NAME")).ToString()
objSplz.ACTVNSTS = IIf(IsDBNull(row("ACTVN_STS")), "", row("ACTVN_STS")).ToString()
objSplz.FNLZSTS = IIf(IsDBNull(row("FNLZ_STS")), "", row("FNLZ_STS")).ToString()
al.Add(objSplz)
Next
arr = al.ToArray(GetType(clsHrmSplzAreasInfo))
Return (arr)
Catch ex As Exception
Throw ex
End Try
End Function

The error states you have too many cursors open. Are you sure this is the code that creates the error ? If so, I assume HRM_SPLZ_AREAS is not a table, but a view, and that it uses cursors. I am imagining perhaps it doesn't deallocate it's cursors and this is the reason for the issue over time ?

No HRM_SPLZ_AREAS is a table.
The following code is to get the rows.
Public Function GetData(ByVal commandar As String) As DataSet
Dim ds As DataSet
Dim AD As OdbcDataAdapter
Try
If conn.State = ConnectionState.Closed Then
conn = New OdbcConnection("dsn=HurmisSystemOra;UID=hurmisplus;PWD=hurmisplus;")
conn.Open()
Dim Mysql As String
Mysql = "alter session set nls_date_format='DD/MM/YYYY'"
command = New OdbcCommand(Mysql)
command.Connection = conn
command.ExecuteNonQuery()
command = New OdbcCommand(commandar)
command.Connection = conn
Else
Dim Mysql As String
Mysql = "alter session set nls_date_format='DD/MM/YYYY'"
command = New OdbcCommand(Mysql)
command.Connection = conn
command.ExecuteNonQuery()
command = New OdbcCommand(commandar)
command.Connection = conn
End If
ds = New DataSet
AD = New OdbcDataAdapter(command)
AD.Fill(ds, "DataGrid")
AD.Dispose()
Return ds
Catch ex As Exception
Throw ex
End Try
End Function
