VS 2010 Dynamically Bind Datasource To ReportViewer
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. I have to close the entire program and reopen it before the changes take effect on my report. This piece is used to bound the report to the dataset

I'm running CR XI, and accessing .RPT files through a ReportViewer in my ASP.NET pages.I've already got the following code, which is supposed to set the Report Datasource dynamically.
rptSP = New ReportDocument
Dim rptPath As String = Request.QueryString("report")
rptSP.Load(rptPath.ToString, 0)

I have a form with a single Report Viewer control on it. I wish to use this single form to display ALL of my application's reports. I am looking for a method that will allow me to assign the rdlc file / table adapter and rebind the datasource at runtime. I've tried various methods but cannot get it working. It sounds simple enough but is now driving me crazy!!

I'm currently using a combo box to select one of many alternatives. From 5 alternatives only 1 works, when i click on any other it gives me the following error:"Cannot bind to the property or column 'xyz' on the DataSource.Parameter name: dataMember" Why is this error caused? What are the possible solutions to this error?

I created a master - detail form . I changed the name of one datacolumn in the dataset (not the source) from "alert_name" to "alert_name_new" and i saved all files.I checked the file <dataset>.xsd in the directory and i found the change was made... as expected.When i try to run the application the following error message appears: "Cannot bind to the property or column ALERT_NAME_NEW on the DataSource."
Note: I use vb 2010 express edition

When I try to use the following line of code:
cboSite.DataBindings.Add("Text", _dtSite.Select("Site <> 'ALL'"), "Site")
I get the following exception:
EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember
details I am connecting to an Access database and using .net 3.5 and writing the code in VB. In this database I have a table named Sites with a column named Site and when I try to use the line of code above I get the exception noted. I was under the impression that I could explicitly name the column that I need to use in my control (combo box).

I have an app that has a DataGridView with a few buttons. My intent is to have the DataGridView populate with the data associated with the button clicked. So if you click the States button it'll fill the DataGridView with the DataSet I have created with a link to a SQL table with a list of States.

I am stuck at a task. What I want is, I am creating a table in the database on the fly in the code behind using the below code(in VB).Now my main problem is I want to display this table which is created in step 2 of a wizard, in step 3 using a GRIDVIEW. But as we all know a GridView needs a sqldatasource for values to be displayed, however what I need for achieving this is dynamically assign a datasource to the GridView, but I am not figuring out HOW?
Dim NewTable As String
Dim FullName2 As String = "Dynamic" + "_" + lblCompanyName.Text + "_" + tbCustomerFileName.Text
'Get Row Headers and map to Fields
readerXML.ReadHeaders()

Using VB 2008. We have an app with a third party grid on it works well enough. This is a small utility within a bigger suite, and adding/updating it involves a simple EXE copy. The issue I am trying to address is that not all customers will have the 3rd party controls on their systems, and we want to avoid deploying them if we can.
Can I build the app so that if the controls are present, the app uses them. But if they are not present, I use a simpler control? I picture using a 'launcher' form that tries to load Form2 with 3rd party. if it errors, then just load Form3 with common controls. But can I even get to that point? With missing controls, will the app even load? I understand Late Binding for objects, but this is a control right on the form. Can I late bind a control and add it to form dynamically perhaps?

my application uses a login form to connect to a remote SQL database, which uses SQL authentification. Normally, I define a connectionstring at design time which I complete with the username and password at run time.I now need to implement a ReportViewer which needs a connectionstring. I want it to use the existing connection however it obviously does not see the coded connectionstring, so I decided to add the connectionstring in app.config.

1. I get an empty page at the end of a report. I have 4 pages instead of 3, 8 instead of 7 and so on. I see and print these empty pages. The report width less than the page width minus margins, so this cannot be the reason of my problem. How can I get rid of these pages?
2. If I have a few controls ReportViewer then to print the report I must to press each print button on each ReportViewer, and each ReportViewer prints with a new page. Have I possibility to print all the ReportViewers consequently pressing one button and to continue the report?

I am creating some reports using object datasources.in my software the user can create a list of products specifying a code, the product name, the price and the vat rate (this last two attributes will be used as suggestions when the user will place the product inside an order).When a user creates an order he can place products within it by specifying for each product the quantity and he can also override the suggested price and the vat rate.So basically i have two models to represent the products:
ProductModel (used to define product name, product code and the default suggestion for price and vat rate)OrderProductModel (used to place products within an order, specify the quantity and override the default product suggestion for price and vat number)
ProductModel:
id
code
name
[code]...
(suppose orderProduct is an instance of OrderProductModel)Now the question is "how to define the report rule to access to code and name?"...I am using visual studio 2010 and by reading here:[URL]they says that the syntax: =Fields!Object.Value.attribute no longer works...

I am currently working on a asp.net page coded via Visual Basic.On the page I have these image buttons that are dynamically generated based on the SQL Data the page retrieves.Unfortunately I could not figure out how to bind a click function to each of these buttons.the [Control Name].onClick = "Function Name()" is for clientSide scripts.and I need to bind
Protected Sub Button_InsertNewTextBox_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_InsertNewTextBox.Click
to the dynamically allocated buttons.

Where can I find resources on authoring Reports. Say, I have a VB project and I want to add reports to it, do I have to add a ReportViewer for each report or can I use one ReportViewer for all?
What is the difference between a Report created using the Report Server Project of the Business Intelligence Projects and one created using the Visual Basic/Reporting Project tab? Which one is more suited for creating reports?Only performance counts!

I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor

I have a ComboBox which is bound with a DataSource from (obviously) a Database. However, there are 659 different entries inside this Database and I was hoping to tack on AutoComplete.
I tried setting the Source to the ListItems since, after initialization and the data is bound, all the items necessary are in fact inside the ComboBox so I had assumed that it would pick that up. I was wrong. I tried using a Custom source but VS errored out saying that I couldn't do that since the ComboBox was bound.
My question is, how can I utilize AutoComplete's "Suggest" mode with a bound ComboBox?

I'm having an issue wherein my combobox is populated from a datasource (access database >> [URL] and unwanted duplicates are shown.
-Example- [URL]
How can I make it so no duplicates arise?
Also on another note...I'm having difficulties linking the 2nd combo (model) to the first (make).
I would like the program to function in such a manner that
>makeCombo is populated from the database
>the user selects the Make of the vehicle from makeCombo
>modelCombo is populated from the database according to the make selected
>the user selects the Model of the vehicle from modelCombo
>user hits search
>datagrid is populated with appropriate vehicles
