.net - Handle Null Nested Objects In RDLC Report That Is Bound To Custom Assembly Object Datasource?

Aug 27, 2009

I have an RDLC report that I am rendering directly to the Response Stream as PDF (rather than using the ReportViewer). In the code that renders the report, it's DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can't seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:

Public Class ClassA
Public Id As Integer
Public Name As String

[Code]....

the report displays "#Error" if TheNestedObject is null. If TheNestedObject is not null, it correctly displays the Name.

Change CSS File Dynamically?

Jun 1, 2011

I have close to 10,000 serverside pages, all of thse use the same stylesheet. I have created a new serverside page which is like a dynamic menu system to help find specific pages from the existing 10,000 pages quickly and easily.

The problem is, that if the serverside pages are accessed the old way using the old menu system, they should retain their old stylesheet. however, if they are accessed via the new menu system, they should use a new refreshed stylesheet.

Jan 19, 2011

I have a ReportViewer showing a report that is bound to a dataset. The dataset gets its data from a Access database backend. I have a separate form that allows the user to add/update/delete data. My problem is when the user makes changes to the data using the data entry form, the report does not reflect those changes.

Tables In A .rdlc File

Jun 12, 2011

There would be more than 8 table controls in the report(.rdlc) and each would hold records that has specific values on specific fields.The fields in my database table are;

1. Year
2. Semester
3. Subcode
4. Description
5. Units

What those tables in my report(.rdlc) contain would depend on their Year and Semester fields. That is, my first table (in my report) would display records whose Year value is "1st Year" and whose Semester value is "First Semester".

Change Datasource For Dataset?

Aug 19, 2010

I have a vb.net window application project that connect to Access database.

I use dataset for all Forms and Reports.

Now I would like to change back end from Access database to SQL Server 2000 database.

I change the connection string(Data source, Data Provider etc)to connect to SQL Server 2000.

But it is not convenience bcos Dataset Designer codes are still connect with OLEDB Provider instead of Sql Client Provider.

So I can't do my application with SQL Server database.

Change Datasource In CrystalReport - .NET?

Jan 27, 2009

I'm using VB.NET 2003 windows application.i'm trying to display Crystal Reports using CrystalReportViewer.

Code i'm using to display "ZTab.rpt" in CrystalReportViewer when Form_Load
Code: Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

[Code]...

for example: if we are using datasource "work.mdb" for "ZTab.rpt" when form_load. when i hit a button, how come i change the datasource to "Employee.mdb" for "ZTab.rpt" during run time using codes. so when form_load it will display ZTab.rpt with datasource "work.mdb" and when i hit a button, it will display ZTab.rpt with datasource "Employee.mdb".

Change Datasource In CrystalReport?

Jan 27, 2009

I'm using VB.NET 2003 windows application.

i'm trying to display Crystal Reports using CrystalReportViewer.

Code i'm using to display "ZTab.rpt" in CrystalReportViewer when Form_Load

Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CrystalReportViewer1.ReportSource = "ZTab.rpt"

[Code].....

so when Form_load, it displays "ZTab.rpt" and when i select one crystal report in combobox and hit button "Run", it displays corresponding crystal report. that works fine.

how can i change the datasource of a report during run time using codes (programming).

for example: if we are using datasource "work.mdb" for "ZTab.rpt" when form_load. when i hit a button, how come i change the datasource to "Employee.mdb" for "ZTab.rpt" during run time using codes. so when form_load it will display ZTab.rpt with datasource "work.mdb" and when i hit a button, it will display ZTab.rpt with datasource "Employee.mdb".

2008 DataSource Stored Procedure Change?

Jul 16, 2009

I have a vb.net project. I have used the GUI and wizard to create a DataSource pointing to a SQL Server Stored Procedure. It works great! However, a new column has been added to the stored procedure.In the GUI if I right click the data source name and refresh, nothing happens.If I right click the stored procedure name and refresh, nothing happens.If I preview data I can see the new column returned.If I choose edit with wizard there is a red exclamation point next to the name of the stored procedure and red X be each column name.

When I hover over the field name it says "Column ABC in the DataSet references a column missing from the Database".When I hover over the stored procedure it says "STORED_PROCEDURE is mapped to STORED_PROCEDURE in the DataSet. Element STORED_PROCEDURE in the DataSet contains columns that do not exist in the Database".I can't figure out how to get the new columnd in the dataset.

Winforms - .net, Combobox.datasource Will Change Selected Index?

Mar 1, 2012

Let me try to describe my problems in the simplest way: I have combobox1 and combobox2. I hope to achieve two things: Combox1 is bound to list1 (a list of string). When a user selects an item in list1, list2 (a list of string) will be obtained from database and combobox is bound to list2.If user specifies text1 in combobox1 and text2 in combobox2, then these two values will be shown in the comboboxes regardless of the bound lists.

[Code]...

So the results of above code is that goal 1 is achieved, but goal 2 is never achieved. combobox1.selected index is always 0 and combobox2.selected index is always 0 too.

Sql - Visual Studio - Change Datasource After Initial Database Server Is Down?

Aug 22, 2010

Ok, so I've got this Visual Studio 2008 Project I was working with about a year ago perhaps. And this project had a datagrid that was linked to an external database running on a server off the internet. Now, this databinding was all done using Visual Studio 2008's built in features. But how can I now change the binding to a different server, without destroying the project? I've noticed that a lot of the code that Visual Studio creates makes a mess. So manually trying to change the datasource has allways f*cked up the whole project for me.

I'm not all that good with this stuff, that's why I used the built in features of Visual Studio. But I noticed that several things appear, like a binding source, and a dataset. Is it possible to do this? Perhaps even better, making these settings be controlled after the program has been compiled. The way it is now, it's all hard coded after compiling, and that kinda sucks. I remember trying to do this about a year ago, trying to bind these settings to variables stored in settings. But I never got that to work. Just throwing around ideas here
