View 4 RepliesI have a code for populate a combobox with the text from a txtfile.[code...]
But i have about 20 comboboxen en i want all of them with this text from the txtfile.
(Every Combobox in the Form).How do i do that ?
I am using a Class_SQL that gets the table, creates the DataAdapter and DataTable.I have a combobox named cboFullname. I can fill the combobox with data from the database, ie: Dim sqlcmdtext As String = "SELECT *, Firstname + ' ' + Surname AS Fullname From Contacts". I can display full records in a datagridview.
I would like to be able to select a name from the combobox and have the record text boxes display the data and be changed with the cbofullname index changed subroutine. Here is my current code to date:
Public Class frmMain Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm trying to assign a datasource to a ComboBox control during runtime. When I do so, I get the attached message. Here is my
cmbAddressDesc.DataSource = dbDataSet4.tblAddressCodes.addrDescColumn
dbDataSet4 is a typed dataset. I want to learn how to use an Interface. The error message is suggesting using an IList. How would I do this. I'm having trouble finding good documentation on this.
I have create a table called Employee and tried to create a link from DataGrid (in ASP .NET ) control to the datasource. I have created and added the connections tring as all using the wizard. When I need to check generate insert, update, delete statements and pessimistic concurrency the check boxes displayed "disabled".

View 2 RepliesIf I used a generic list Class to hold data objects that I am pulling from SQL Server using Linq to sql to populate a datagridview would I need to make any modifications to the datagridview control to accomodate multiple columns or would I need to make any modifications to the generic list class to accomodate the multiple columns in a row that is typical of a record in SQL Server? And one more thing which I believe is the easy part. To bind the list to a datagrid view would I just use the datasource property of the datagridview control.
View 2 RepliesI have a form where I have to use control arrays to create a multiple input form i.e. rather than processing one transaction at a time up to 16 transactions must be processed. The following really havent given me much problems at this moment labels and textboxes. I use a for construct to create all the controls including a combobox. This is where my question comes in this form combobox has to be linked to a table in a database. But furthermore and this is where it gets complicated for me anyway each seperate combobox must move independly if i select row 5 in the table in combobox 4 combobox 5 which is havent touched should still be on row 1. How do I accomplish this. I'm using a webservice. I have tried passing a loaded dataset . The code that loaded the dataset is as follows
Dim DSInfo As New Project1.localhost4.AccInfo
DSInfo.Credentials = System.Net.CredentialCache.DefaultCredentials
InformationData.Merge(DSInfo.GetBusinessJournals)
[Code].....
this code doesnt however provide a link to the table equallly creating a dataset in the combobox method ,loading it and then setting it as datasource also provides no link. I know i'm missing something.
I have a list of customers (over 50k) that I am trying to change the way my users search and interact. Presently, they fill in parts of a first name, last name, home phone field(s) and then click a button and it searches and presents a listview list to the user for selection of the one they are trying to find. Fairly straight forward behind the scenes with a customers object making the call to the sql server on the network and returning customer objects as indicated. I want to add a datagridview control and display all customers and then have a textbox for the user to type their selection into and have the datagridview update accordingly.
I want the filter to be dynamic as the user is typing. What I have so far is the datagrid loaded with data and the text box. I also have a stored procedure that takes a string(the text box) and returns the customers collection object as the "new" datasource. But as you are guessing, that is to many calls to the database over the network. Just not very efficient. Once I have the original collection object, how can I filter it dynamically in memory as the user inputs characters into the textbox.
I need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.

Is there anyway to carry one combo box from one form to another without the use of loops? I'm trying to figure out if it would be easier to represent a comb box in a new form, or if it would be easier to show it in a print preview window....
View 2 RepliesI have a couple of texbox and combobox controls that are bound to a dataset. I can scroll this with the a bindingnavigator. But I want to have the combobox do autocomplete from the dataset. For example, if i type a "D" in the combobox bound to the 'ClientName' column of the 'ClientInfo' table,i want the comcobox to display all (or maybe the top 20) names that start with a "D". If i then type an "E" I would like the list to show all names starting with "De" and so on.
I have tried to bind the 'autocompletesource' of the combobox to the 'ClientName' column, but that did not appear to do anything.I am reasonably experienced with VB .Net, but totally new to database and data centric applications.
