I have a combobox that is databound to my webservice. Code works perfect.

My issue is I need to be able to call that function from another form. I have a form that I add a new customer with and want to refresh the data in the combo box, and select it has the selected item. How do I do this? I have tried several ways, and it just does not work.

I'm trying to bind data to a combo box but it does not appear to be working. I've setup the DataSet and the DataSetBindingSource and all this appears to be working, within the form design I can expand the little arrow in the ComboBox control and preview the data. This appears to be working but when the application is run, nothing appears in the drop down box.
I have the following code in place:
Code:
cmbSelectCompany.DataSource = ContactsDBDataSet.Company()
cmbSelectCompany.DisplayMember = "CompanyName"
cmbSelectCompany.ValueMember = "CompanyName"

i try to bind database to combo box but having (Object reference not set to an instance of an object) error during the running.
I've done data binding to my Combos and it works fine but my data base has over 260 000 entries, so I can't let user to move trough it, one by one entry until finds a match.What I am looking for is that user select value from Combo Boxes and Text Boxes get filled in with a matching values from the same row.Auto Complete helps in selection but I still can't work it out how to get values to my text boxes.

View 3 RepliesI am having a problem setting up my combo box to pull its menu from a SQL Server table and store to the main data table.Currently my drop down list displays correctly but saves 'System.Data.DataRowView' to the data table. My main data table is called 'Survey' with staffname as a column, then I have another menu table of staff member names which populates the drop down menu.I found that when I remove the DataSource and populate the Items collection instead the combo box saves the correct value as expected but when I use the datasource it saves the words ''System.Data.DataRowView',[code]

You have a pseudo-table class and a pseudo-row class. The row is somewhat generic and has no strongly-typed fields. It follows the typical dictionary interface
Dim age As Object = person("Age") 'accessed via default property Item
vs
Dim age As Integer = person.Age 'an actual property typed as an Integer
What's the pattern to use so that we can bind our pseudo table and its rows to a grid or combo box?
Dim rs As New clsResultSet(tblPeople)
Dim id As Object = rs(0)("Id") '913
Dim name As Object = rs(0)("Name") 'Ted[code].....

Basically I'm using the following code to access a php file I created that creates an XML formatted page.
xmlFile = XmlReader.Create("http://www.serysoft.com/webservice.php", New XmlReaderSettings())
The purpose of webservice.php is simply to access my MySQL DB and put the relevant data in tags. Then I use:
Dim ds As New DataSet
ds.ReadXml(xmlFile)
vi.user_version = currentVersion
[Code]....
To stick the information in a dataset then read that information into a Public Structure I have created. This is all contained inside a DLL which is being referenced by my main program.
The issue I'm having is that in the SQL DB, the "notes" field is a BLOB. I have information that needs to retain line feeds. However, when put into the XML format, it loses the line feeds and becomes one line.
Do I need to talk to someone about PHP to get this done? Or is there some known way to handle such a thing as far as XML goes?

how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

View 7 RepliesData binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

View 1 RepliesI have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that. If I use the data visualizer I can see the name I am after, I cannot figure out the call to extract it
Bindingsource1.DataSource = GetData("Select * From PURCHASE_ORDERS WHERE PURCHASE_ORDER_NUMBER =" & REQ_NUM.Text)
.DataSource = Bindingsource1

View 2 RepliesI have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.
View 4 RepliesI have produced an Access database and a dataset linked to the database, and am working on a form in VB to enter data to this database. This form was produced by dragging the required fields from the data sources manager to automatically bind to the dataset.
I am attempting to use some radio buttons to allow users to select their gender on a form. I do not know how to take the results of selecting either radio button and upload the user's selection to the dataset, which would then be uploaded to the database.I also attempted to use a ListBox and ComboBox for some other fields, but they do not seem to work as they should, since when I attempted to press the handily provided "Save" button, I was provided with an error to the effect that the boxes appeared to be empty.
i make this code to bind combobox and i insert the item to the combobox

I have developed a form for Windows VB.Net that uses a number of text boxes that are indidivually bound to separate columns in a database. When one of the textboxes (let's call it XYZ.Text) is bound to the database, it prevents the data from any of the other bound text boxes to enter the database. When the binding for this one text box (XYZ.Text) is removed, then all the other text boxes work fine.
