Filter Combobox Contents By Text In Another Combobox
Jun 22, 2010
Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. 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" SELECT ST_UID, ST_NAME FROM STATE
For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY 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.
I then tried to convert the value in the st_uid label to an integer:
CODE:
This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name
What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.

I think my question is discriptive, or as Microsoft in the Documentation for Data Grid the question is, How do I have a combo box column display a sub set of data based upon the value of a different combo box column?

But now my task is when i Type the text in the Combobox the related data should be filter in the DataGridView.If i type any letter in the Combbox the datagridview rows starts filter.
For Ex: Names are like 'Mali', 'Malu','Maal','Mouli'.

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.
This is for VB.NET Windows Application

I got my regular fields like firstname,lastname, gender, birthyear, street, city, zip, phone. Which i can search through by just entering one of these fields.
Then i got a dropdown box which i was hoping to use a filter on. Every file is in a cabinet, but since those are somewhat alphabetically i have more then 1 cabinet for certain letters. This is why i wanted to use a filter to get a list of all people in a certain cabinet.
So i want my dropdownbox to automatically show the cabinets that are in the database(for example A...Z). If i choose B from the dropdownbox i want to see all the names that are in that cabinet in my datagridview.

I am making a combobox dropdown to filter a report. I am using the table adapter to query the data and fill the report from the selected item in the combobox. However, if the user select index 0 (which is "-Select User-") , then the query should disable the filter and select all users in the database. How would I go about doing this with these 2 conditions?

who can clearify more about how to link the relationship between a Local database to ComboBoxes as an example below:
1. ComboType: it will show only kind of audio file extension
2.ComboCompany: will show only the music company name we added
3.ComboVolt: will show of album volt
How it work
If we've selected the ComboType Ex: mp3 file then in the ComboCompany After we have selected with any album name.
The last result is in ComboVolt the number of volt will show up base on we have selected the name of any company name in ComboCompany.

I have a CombBox and a data grid view on a form, when the form loads, the data grid view is loaded with data from the database. I want to filter that data with a selection from the combobox (which is loaded with data from another database). The code i have is as follows:
ContactsBindingSource.Filter = "Company Like '%" & Me.cmbSelectCompany.Text & "%'"but when I select an option from the drop down list the DGV gets cleared down as if my selection has no equivilant data in teh DGV.

Kinda new to working with wpf apps (and vb.net). Looking for a way to filter a datagrid using a combobox (to select the field that the user wishes to search) textbox (to input search terms for specific records). The datagrid loads fine as does the combo containing the fields, however my filter simply does not work.
Code for loading data (works fine)
Dim obj = Me._dataManager.Collections.ReturnCollectionByID(tableSelectionCombo.SelectedItem.TableID)
Me.DataGrid.ItemsSource = obj
obj.Load(New DataManagementDataRequest(Nothing, Nothing))
Code for filtering (not working)
If Me.searchTxt.Text IsNot Nothing Then
obj.filter = selectFieldCombo.SelectedItem.ToString Like searchTxt.Text.ToString
Else
obj.filter = ""
End If

I have a combobox (cbKeyWords). I want to make sure tbAddEdit.Text does not already exist before I save. To me I should be testing for a False result not True. But the above code, goes to the msgbox if findstringexact=false and saves the data if it's true.
