I have one problem solved, properly converting text to numbers. Now I want to use that conversion as a selection parameter in a FillBy statement.I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US. This is what I used for the Table Adapter Configuration Wizard for the combobox "State". [code] ST_UID is an Integer. I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5). The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state. [code] Problem is I'm not getting any results, the "County" combobox is blank. I've tried a lot of variations on the code, such as % StUID %, etc., but no luck. I have experience with VB 6 but am a beginner with .NET.
Is there a way to update source combobox to printer combobox selection?So going from printer1 to printer2 the source will update according to what that printer has to offer.
I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.
I have two comboBoxes, one is CountryCombo and second is StateCombo.What I want is the that when i the clicks country combo and select a one country then the States of that the country should get populated in the State Combo.I have tried things many many many but nothing working.

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range Dim data, i As Long, j As Long With Sheet1

I have put all of the items from my Database into a Checkbox Selection, I now want to take the selection that the user makes from the checkbox and turn that into a string that I can then COMPARE through antoehr table.[code]...
I know this seems like a .Net 101 question but everybody has their own way of programming and I'm curious as to what is the preferred event for checking a ComboBox when a user makes a selection?
Is it possible to have a different selection of values in the 2nd combobox depending what was picked on the first combobox? For example an American state is picked in the first combo box and the second combo box loads the cities in that state? I'm just using a basic form in Visual basic 2010 there is no database behind it.
I have a vb application sitting on an sql server with 4 different tables. I want a scenario where when I select any table from the combobox, every query I will run should use that table as a reference.
E.g. ComboBox values(tables)=A,B,C,D
If A is selected then SQLQuery="Select * from A "
If B is selected then SQLQuery="Select * from B " etc
On my form I have three fields and a datagrid view.One field is a combo box.All fields are databound.The datagridview is a detail grid, bound in the "normal" way. Scrolling through records, etc., all work fine.What doesn't work is when a selection is made using the combo box.The underlying table has a self-join of one-to-many: ParentID, ChildID. ChildID is the main ID for the underlying table.Children may have a parent This is just by way of example.So, the combo box's Value is bound to ChildID, and the SelectedValue is bound to the ParentID.On the form one chooses the Parent with this combo box.When I test this arrangement, I select a Parent, then click Save (using the default toolbar actions). However, the combobox seems to "reset" the selection to the first in the list.
I have a ticketing system that reads a MS 2003 MDB. I can easily fill the DataGrid view with all of the items on the data set How ever I need to be able to have agents filter the rows by login(key)

I cannot seem to load the saved .rtf document into the richtextbox when i click on that file in a combobox. I checked msdn and tried what it suggested, but got no results.
I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
How can i bind a comobox selection to a datagridview without writting code...
i Need to select an item from a combox and based on that item refresh the datagrdiview. I did something like that in Access but i don't know how to make it work in visual studio 2008.
once i select the datagridview itme that i want to edit i'd like to be able to update back to the database. I know i need to write code for this but at least i'll have the data refreshed on the datagridview.
I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.
Here is the code for the Save button: 'Save changes to Locations db Private Sub btnSaveClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Private Const LuxuryRate As Double = 74.84 Private Const FullSizeRate As Double = 48.44 Private Const MidSizeRate As Double = 44.91 Private Const CompactRate As Double = 30.46
And a combobox that lists each option. How can I set an if statement that uses these values if the option is chosen from the combobox? This is going to be part of a calculation performed when the button is pressed.

I have a DataGridView with two columns. One is DataGridViewComboBoxColumn and other is DataGridViewButtonColumn. To capture the button click from the DataGridViewButtonColumn, i have written the CellClick event and it is working fine. However, this is not making my selection from the DataGridViewComboBoxColumn 'smooth'. What i mean is that i have to click on the combo-box twice for it to show the drop-down list. I have noticed that at every click, CellClick is fired. But only after the second click the drop-down pops out. What is the work-around for this?
I have a combobox on a form with the dropdownstyle set to drop down. Users can either salect a value from the list, or type in any value they wish. This all works fine. However, when one particular item in the list is selected I wish to set a different value. Unfortunately I don't appear to be able to set the combobox Text property from within any of the events that fire when the selected item is changed.
i'm new here and a little bit of a noob anyways i'm using VB.NET 2008 what i'm trying to do is list about 7 items in combobox1 and then depending on the selection list certain items in combobox2 but if the selection in combobox 1 changes then combobox 2 items need to change as well.
