Filtering Using Combo Boxes And DataGridView?
Mar 20, 2010
I am building a simple GUI to view data within a database. I am getting stuck when it comes to filtering data. I have followed Beth Massi's video entitled How Do I: Filter data on the client?
However my datagridview will not filter, it simply moves the highlighted cell down to the location of the item selected in the combo box. The items in the combo box are also repeated as opposed to grouped by what they they are called, for instance I have a column called region and every cell contains the text "West" and the combo box just shows a list of all the cells as opposed to just one.I followed the video several times and every time this happens. Even with a new project. Could it be because my data isnt a table but a query of several tables? I can filter on this data in excel and access easily.

I am pretty new on programing and for the past 2 days Iīve been trying to paint a table grid based on the selection made on 5 combo boxes. My problem is that I am trying to fill the combos based on the selections made on the other combos and really I am going insane. I have found a couple of examples that show how to do this using JavaScript but I donīt think this is the best solution. i would like to do this using a stored procedure which I think is more efficient. My db is on SQL 2000 and I am using asp for server script.At the moment all i have is this, which really doesn't do very much, all it does is composing the where clause so that whe i call the stored procedure if filters the results based on the combos, but ofcourse the combos are at the moment static: [code]

i am using a couple bound comboboxes in a bound datagridview. It seems though, when the combo's are changed, and the tableadapter is filled again, the changes are not being saved to the table. Is there a special trick to getting the data in the combo boxes to saved when the values are changed?

I have a datagridview bound to a bindingsource. This datagridview contains one column which is a combo-box.
Upon a click on a button,I change the underlying datasource. The selected values of the combo-boxes change.
But the change doesn't appear on the screen ! To make the changes visible (refresh each combo-box), I have to hover on the datagridview with the mouse or use the scrollbar !
Question 1 : why do I see this ?
Question 2 : what should I do to make the changes immediately visible ?

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.

I am having trouble filling my datagridview from a separate combobox selection.On my form, I have a datagridview that displays all the contents from my tab delimited text file (customers.txt). Also, on the same form I have a combo box that displays all the customers names.
Once a user selects a name, the datagridview should populate details about the selected customer. I figured out how to fill a multiline textbox; however,I want to fill a datagridview instead but am unsure how to go about doing so.Code for filling mutiline textbox with customers details

I need some advice I have a bound datagrid and a bound combobox lookup on a form. What i want to do is filter the combo box so it only shows the items left that are not in the datagrid already.
I have managed to achieve this already.But when the program runs, and there are items displayed in the data grid the combo box items are now filtered.The program crashes as it can't display the combobox item as i have filtered them out. The program runs fine if the datagrid is empty (IE combobox items not filtered). But as soon as there is a record in the datagrid when i save the database and refresh the combo box the program falls over is the items it is looking for is not in the combo box items list.
What would a work around be. I have thought of a separate combo box that is hidden and use the datagrid combobox events to show it in the correct position.Just to be tedious the displayed item is not the stored item value

I am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.

I was having a heck of a time populating a gridview combo box.I learned a ton in the last 48 hours but would really like to know the answers to the bottom three questions.You guys are the experts, so I'm hoping you will enlighten meBut the summary of it is below:I was never able to get the ComboBox to bind to the data source. I tried everything until I turned blue. So I went to the basics and coded all the automatic stuff. I'm curious as to why the automatic binding didn't work. Perhaps its because my gridview datasource was LINQ.Here is how I pulled it off. I hope someone down the road benefits from the last 48 hours of my delima:First of all, know that I have two drop down lists on my form, one is the GPField and the other is the BankField. These are already populated DDLs that are static. So I used them to cheat on the values instead of using enums.
Sub fillGPFieldListDDL(ByVal obj As Object)
Dim db As New CompanyDataDataContext
Dim myConn As New Connection With {.ConnCls = ConnCls}

I have two combo boxes: cboRepairCategory (plumbing, landscaping, etc) and cboVendors. I am using Stored Procedures in SQL to store the data from my database and then load them into the combo boxes.The cboRepairCategory will be loaded first. Once the user has selected what type of repair it is I want it to restrict the amount of vendors that can be selected, so instead of saying:CREATE PROCEDURE dbo.up_Fill_Vendor_Combo
AS
SELECT VendorID, CompanyName
FROM Vendors
[code].....
I would select only the vendors that have the RepairType of say Landscaping, so thecboVendor would load now only Vendors with Landscaping instead of all vendors.My question is this: Is this done in SQL in my Stored Procedure or is it done in VB in my functions for my combo boxes. I've never tried this before I am totally lost on it. I have fiddled with the code on both ends but to no avail.

I have a school project where i have a form that works as a class registration. There is cboGradeLevel and cboCourse and cboNumber. If cboGrade level is freshman i only want the numbers that start with 1 in cboName to be displayed, sophomore =2, junior =3, senior =3. Then i want cboCourse to work the same for the second number in cboNumber. english=1, history=2, math=3, science=4. So if freshman and history were selected i only want the numbers that start with 12- to be displayed. What can I use to make this happen?

I am using the following code for populating the combo boxes in my application. It is really nice. If any one requires, may use this. It takes three parameters. The first, the name of the Combo Box and the second, the SQL Statement to populate the combo box and the third is the number of column to be displayed (from the SQL statement)

I need to know how to clear what is currently in the combo box with a 'Clear' button. Basically, I have a combo box with a list of destinations for the user to choose from. Say the user selects Australia, when I click a clear button, I need this selection to disappear, and be ready for the next user to select a destination.

I am trying to get this Program to print. Most of it is working correctly except for the part of the Fragrance. When it prints it is printing the whole list not what I selected. The exterior and interior are printing correctly and I tried to set the combo box up the same way. I did the debugging and I can see it loop thru the printing process over and over to get all the names in my list. I just don't see why it is doing it or how to stop it.

In my program, I have recently found it necessary to include a settings window. Here, there are two "Combo Boxes" which the user can click on and decide what to select. For example, in FireFox, under Startup and "When Firefox starts: you have a selection. This is what I want integrated into my program. Also, when the preferences have been selected, they can click an "apply" button in which their input can be recorded into a settings file. At this point I do not know where to go. Another important thing you should know is that all of the input is based on "Yes/No (Boolean).
