how to bind a listview to my .mdf dataset. how would i also manipulate the binding navigator that comes with datagrid view or details view when you put the fields on the form with buttons i want to add apart from the ones on the navigator itself?
I am trying to bind my SQL param's qurey to bind to a table. My problem is i get this error "Fill: SelectCommand.Connection property has not been initialized."
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click If RadioButton3.Checked = True Then Dim connectionGrid As SqlConnection = New SqlConnection("Data Source=BST;Initial Catalog=dsfs;uid=dfsdf; pwd='dsfsf'") Dim commandgrid As SqlCommand = New SqlCommand()
I use a dbDataAdapter to populate a DataTable from an unlinked oracle database.I have a dbDataAdapter that I want to insert rows into an SQL Server table using SQLCommandBuilder.I have been trying all day to update the DataTable that references the SQL Server table with the data from the Oracle DataTable so that I can insert the rows.
In my vb6 I bound my data directly to the database but I think it might be better to use the the dataset in the updated version.[code]...
I can do a for each statement on the quary now but how can I set it to a variable as to use the move first, next ect. Also, does anything need to be closed/dumped after the execution of the quary?
I am looking for a vb.net example of how to bind a dataset/datatable to data repeater and have the data elements bound to the columns of the dataset/datatable?
I have a module where i have specified the connection string as below:
Public Function Connection() As String Return "Data Source=192.168.0.1,1433;Network Library=DBMSSOCN;Initial Catalog=test;User ID=sa;Password=123456" End Function
Then i have a form which has two textboxes. What i am trying to do is bind the two textboxes to a dataset in the following way:
Imports System.Data.SqlClient Public Class Form1 Inherits System.Windows.Forms.Form
I'm using Visual Basic 2010. I have my dataset in my program. I'm have several combo boxes on the form that I was able to bind the particular table with the information from each table to most of the combo boxes by dragging and dropping them onto the combo boxes. However, one combo box in particular must be populated by code. When a user selects, let's say "a" from one combo box, I need the next combo box to display information in certain tables only, based upon their choices in the previous combo box.
it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)
I am using Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items
This is my first post here so forgive me if I am not following any correct protocols. I am attempting to generate a DataSet and bind it to a datarepeater object. I had been doing this at Design Time and was getting an error message when filling the dataset when the form loaded. So I am basically createing the dataset in my code now when the form loads and binding it to the datarepeater. However, when I attempt to bind the dataset I get a NullReferenceException - even through I know that there are 60 rows of data in the dataset table.
[Code]...
As you can see i have several debug messages in there. I get the error on the last line when setting the datarepeater data source. I try and get data for a specified lot - if it doesn't return any values I create some values in the datatable and add them to the DB. On first load when there is no data this works perfectly. If I then close the form and reload it, it will display fine. However, if I change any of the data (database is updated) and then go back in again, I get the error above.
I think my subject sums up what I am interested in knowing. I am looking to create a chart where Series1 is from Table1, Series2 is from Table2 in the given Dataset. My code below doesn't throw any errors, but it appears to be grabbing the data for each series from the first table.
Imports System.Windows.Forms.DataVisualization.Charting Public Class Form1 Public Sub New(ByVal ChartData As DataSet) ' This call is required by the designer. InitializeComponent() [Code] .....
Is this code correct to fill this table? If not, why? Honestly, I've found several perspectives on how to do this sort of thing, some of which are linked below:

I want to Bind a BindingNavigator to a table using OLEDB or any other method (excluding the automatic stuff for increased complexity of my CW). I bound the Data Grid to the data using the following code
Try Dim DA As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter("SELECT Question.Question_ID, Question.Question_no, Question.Question FROM Question INNER JOIN Quiz ON Quiz.Quiz_ID = Question.Quiz_ID WHERE Question.Quiz_ID =" & GetID(combQuiz_Title.SelectedItem), myConnection.GetConnection)
[code]....
Then I created my own delete and save commands. But I dont how to do the same using BindingNavigator
I had a previous thread asking how to make an unbound column work, but quickly found that this causes huge performance issues. I have a table called TieIns, it contains a column TieIn_ID and some other various information.
is there a way to caputre the values in a datagrid and bind them to a sql table? I have a datagrid bound to a sql query with some editable cells and I wanted to know if the updates could be sent back to the sql table. is there a way to set the updated datagrid to a new dataset and bind the new data to the existing sql table?
I have a large form that is set up from master-detail datasets in Visual Studio 2008.I havene master table with a large amount of detail tables. Several of the detail tables also have detail tables linked.Now I need to add a master table that sits on top of my existing master table making it a detail table.
I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable" Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
but now i have another problem in datasource property that is i want to binding more than one table so that all table's data rows can be displayed in datagridveiw control. suppose i have two table as per order no..
I have a DataSet with many tables and a single DataGridView. I need to select a value from a combobox and then pressing aButton to show the selected table to the DataGridView. For example if I select from combobox "Selection1" I would like to show to the Datagridview the contents of the table called Selection1. I paste the event that I thought might work but doesnt show a think: Private Sub aButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles aButton.Click
I have the following overloaded functions I use to fill a combobox.The first function works the way I want it to except for the fact that I pass a combobox in. I wanted to create a simpler function, thus my second attempt.For some reason the line:tempCombobox.DataSource = tempTable does not bind the data table to the tempCombobox. What am I doing wrong?
i want to read the data from the table to textbo.below is my code when i try to run it it shows the error following are error.IndexOutOfRangeException was Unhandled
Make sure that the max row on a list is is less than list size...
How do I set ListView data through the codebehind instead of using the Bind() function in the Text attribute?Right now I'm doing the following, but I'd like to have it retrieved and set in the codebehind. I'm using VB..
see i have a form in that i have following controls
.combobox .textbox .listview
the combobox contains all the column names of listview like docid,firstname,surname etc
when the form is loaded the listview is populated with some data from the database.
is there is anyway to autopopulate the listview control based on search term entered on the textbox.i heard about the "onchange event",but i'm not sure how it works .
