Hi,
I am using repeater and i am pulling data from the datatable which itself is pulling data from the string arrays. My datatable and the repeater code is like this:
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Year");
and the repeater code is like this:
DataView dv = dt.DefaultView;
rpt1.DataSource = dv;
rpt1.DataBind();
where rpt1 denotes repeater.
The ascx code for repeater is like this:
<asp:Repeater ID = "rpt1" runat="server"
onitemdatabound="rpt1_ItemDataBound"
onitemcommand="rpt1_ItemCommand" >
<ItemTemplate>
<asp:Label ID = "lbl_Year" runat="server" Text='<%# Eval("Year") %>'/></li>
<asp:Label ID = "lbl_Name" runat="server" Text='<%# Eval("Name") %>'/>
<asp:Label ID = "lbl_ID" runat="server" Text='<%# Eval("ID") %>' />
</ItemTemplate>
</asp:Repeater>
There is no problem in the output. It is showing data. But Now I want these data based on the Year. Like "Year" as a title and under that Name and ID should display. Any ideas??

Not exactly sure what you want but if you want to show the name and id labels below the year then use the br tag not li.
If you want year to be an expandable section then you have a bit more work.

No not that kind. Well there are Year data like "2007", "2008","2009","2010" and the Name and ID are unique. So I want to show some think like this:
My datatable has data like this:
Year Name ID
2007 Architecture arc1
2008 Architecture arc2
2009 Architecture arc3
2010 Architecture arc2
2007 Engineering eng1
2008 Engineering eng2
2008 science sci2
2009 science sci3
2010 Engineering eng4
2010 science sci4
And i wanted to show like the one shown below:
2007
Architecture arc1
Engineering eng1
2008
Architecture arc2
Engineering eng2
science sci2
2009
science sci3
2010
Architecture arc4
Engineering eng4
science sci4

Hi Mark,
I got problems when using nested repeater. Well if i dont use nested repeater, the parent repeater is getting data from the datatable but when i use nested repeater under that parent repeater, data count in parent repeater is showing zero for the same user. i even break point in all the steps and the datacount is zero when i use the nested repeater. I dont know why is that happening ..

Without seeing what you are doing how can anyone possibly answer? The repeater doesn't change your data.

Ok. Let me show whatever I did so far.
I am using repeater and i am pulling data from the datatable which itself is pulling data from the string arrays. My datatable and the repeater code is like this:
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Year");
foreach (string se in sec)
{
DataRow dr = dt.NewRow();
Name[] sf = Name.FindByID(se.ID);
dr["ID"] = se.ID;
dr["Name"] = se.Name;
dr["Year"] = se.Term;
dt.Rows.Add(dr);
}
and the repeater code is like this:
DataView dv = dt.DefaultView;
rptParent.DataSource = dv;
rptParent.DataBind();
where rptParent denotes repeater.
The ascx code for repeater is like this:
<asp:Repeater ID = "rptParent" runat="server"
onitemdatabound="rptParent_ItemDataBound"
onitemcommand="rptParent_ItemCommand" >
<ItemTemplate>
<li>
<asp:Label ID = "lbl_Year" runat="server" Text='<%# Eval("Year") %>'/>
</li>
<asp:Repeater ID = "rptChild" runat="server" >
<ItemTemplate>
<ul>
<li>
<asp:LinkButton ID ="lnk_Name" runat="server" Text='<%# Eval("Name") %>' CommandName = "GoToPage" CommandArgument ='<%# Eval("ID") %>'/>
</li>
</ul>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
And corresponding databound code is:
protected void rptParent_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
RepeaterItem item = e.Item;
rptChild = (Repeater)item.FindControl("rptChild");
DataRowView drv = (DataRowView)item.DataItem;
rptChild.DataSource = drv.CreateChildView("rptParent");
rptChild.DataBind();
}
Now when i don't use rptChild repeater, all the data is showing . No problem with that. But when I use rptChild repeater as shown in above codes, data is not showing. I tried it using breakpoint too. No error but it is not showing any data count in rptParent repeater.I tried this using
rptParent.Items.Count .
The count is 4 when i run the program without child repeater but it is 0 when i run the program with the child repeater. Can you tell me why this happens and how can I get out of this error ?

Hey,
I found the error.
when i the cursor comes to this code
rptChild.DataSource = drv.CreateChildView("rptParent");
it throws the exception.
It said "The relation is not parented to the table to which the Dataview points" .
But what can be done in this case ? Any ideas ??

It helps quite a lot when you learn to use the debugger.
The exception is very obvious, you have not create a relationship. How does the framework know the data in a DataTable has any relationhip unless you tell it. Software development isn't magic.

Reading the documentation and understanding the tools you are working will help great deal.

Hi,
I having trouble with assigning dynamically checkbox's Checked value using values from a datatable.
Here's my code
<asp:checkbox runat="server" id="chk1" checked="<%# (DataBinder.Eval(Container.DataItem,"Enable")) %>">
How can i automatically convert the field Enable which is from datatable so it will be assigned as Checked's value?
That field's type is bool and values 0 or 1.
Many Thanks!

Checked='<%# IIF(ISDBNULL(Eval("dbFlg")),0,Eval("dbFlg")) %>'>

i made a Web Service project in visual studio 2008.
then added 2 "Web Service" files to the project.
Service1.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <system.web.script.services.scriptservice()> _
<system.web.services.webservice(namespace:="http://tempuri.org/")> _
<system.web.services.webservicebinding(conformsto:=WsiProfiles.BasicProfile1_1)> _
<toolboxitem(false)> _
Public Class Service1
Inherits System.Web.Services.WebService
<webmethod(true)> _
Public Function HelloWorld() As String
Session("foo") = "bar"
Return "Hello World"
End Function
End Class
Service2.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <system.web.script.services.scriptservice()> _
<system.web.services.webservice(namespace:="http://tempuri.org/")> _
<system.web.services.webservicebinding(conformsto:=WsiProfiles.BasicProfile1_1)> _
<toolboxitem(false)> _
Public Class Service2
Inherits System.Web.Services.WebService
<webmethod(true)> _
Public Function HelloWorld() As String
If Session("foo") <> "bar" Then
Throw New UnauthorizedAccessException
End If
Return "Hello World"
End Function
End Class
After i made a windows application, where i made a "Service Reference" to both web service classes/files.
The problem is that Service1.asmx doesn't share it's session with Service2.asmx,...
I get the thrown "UnauthorizedAccessException" on calling "Service2.HelloWorld()" because the session is not created in Service2.asmx after calling Service2...
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim bhp As New System.ServiceModel.BasicHttpBinding
bhp.AllowCookies = True
Dim x As New ServiceReference1.Service1SoapClient(bhp, New ServiceModel.EndpointAddress("http://localhost/ImsBrowserWebService/Service1.asmx"))
Dim y As New ServiceReference2.Service2SoapClient(bhp, New ServiceModel.EndpointAddress("http://localhost/ImsBrowserWebService/Service2.asmx"))
MsgBox(x.HelloWorld)
MsgBox(y.HelloWorld)
' Dim x As New localhost.Service1
' MsgBox(x.HelloWorld())
' Dim y As New localhost1.Service2
' MsgBox(y.HelloWorld())
End Sub
End Class
How to share the session between those files,... In Visual Studio 2003 it works fine when calling the service from javascript,... Now in visual studio 2008 with the soap client wizards it doesn't...
Any help would be welcome,
...

Having problems with free PDF library sharpPDF and allowing it to write PDF file to child directory within ASP.NET application. The PDF is created just fine in my development environment but when deployed to production application (on same computer just separate folder) I receive the below exception.
I tried several different things such as:
- adding <trust level="Full"> to my web.config file for the application.
- verifying NTFS security settings on app directory. Added IIS_WPG with modify privileges. IIS_USRS had modify access already. As well NETWORK SERVICE has modify privileges.
Let me know any suggestions.

ASP.NET has it's own user-account, called ASP.NET[^]. Does that one have the appropriate rights?

Just tried that. Didn't notice that user account, but it doesn't work. Still receive exception.
|
|
|
|

My apologies, simply assumed that the account lacked read/write rights. You could try changing the trust level[^]

The error says "please contact your system administrator or change the application's trust level in the configuration file"
Did you do that?
|
|
|
|

Yes. I tried that with the below excerpt from my web.config file...The articles on this subject were very confusing, so I was hoping someone could shed light on if this is the proper direction for fix.
Regarding the below config file excerpt there were some articles that had a blank "originalurl" attribute. I tried that as well, and till same exception.
Could it be a trust level associated with the specific library?
<system.web>
<trust level="Full" originUrl="" />

Hi
I am showing some data from the database in the repeater like this.
<ItemTemplate>
<asp:Label ID = "lbl_CourseName" runat="server" Text='<%# Eval("Name") %>'/>
<asp:Label ID = "lbl_SectionID" runat="server" Text='<%# Eval("ID") %>' Visible="false"/>
</ItemTemplate>
So now what i want is when i click the Name, it should go to the "admin.ascx" page along with the corresponding ID. Any ideas ??
