Filter Datagrid With Combobox And Prevent Doubles
Mar 15, 2012
I'm trying to create a Select Distinct query, but i'm getting stuck with either an empty combobox either a filled combobox that displays all the doubles.or a message "System. Data. DataViewManagerListItemTypeDescriptor".I have a form (form5) with 1 combobox and 1 datagrid. The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname".[code]I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles.I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i chooses but doesn't filter.[code]I use the "Me.EmployeesTableAdapter.Fill" method so mu question is, is it possible that i don't need to use the OLEDB connection or do i still need this to correctly connect to the DB (access)? I changed the script that i brewed together as displayed above, but this did not do the trick.

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?

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 dataset (imported from a XML file) with double records (clientname), and I want only the records with the most recent date (datetime field) written to a SQL database. Now I sort the dataset ("clientname ASC, DateTime ASC"), so the newest entry is written to the database.

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.

using strongly-typed ms access 2007 database , vs 10 i have a problem with datagridview filter i have 4 columns and allowDBnull is true , null value is empty my problem is that i need to have 4 textbox to filter the columns so i used in the texchanged
Me.PartsBindingSource.Filter = "Convert(partsn, 'System.String') LIKE '%" & TextBox1.Text & "%'" & " and Convert(description, 'System.String') LIKE '%" & TextBox2.Text & "%'" & " and Convert(Position, 'System.String') LIKE '%" & TextBox2.Text & "%'" & " and Convert(model, 'System.String') LIKE '%" & TextBox4.Text & "%'"
which works just fine , except for the rows which contains any null value as those rows are hidden all the time once i change the text, even when i clear the textbox they keep hidden i can only see them once the form is loaded to cut it short, i need to make a filter to the datagridview , that filter should show the rows even if one of the cells is null?

how to filter the datagrid view? what i mean is, the data that will only show in the datagridview depends on the date selected on the DateTimePicker(dtpDate) example if the value of Date is march 20 2012 the data that will only show on the datagrid view is the event that is save on the march 20 2012. also to arrange it ascending based on time.

Is there a way to prevent a user from entering data into a ComboBox, rather then selecting, or can anyone suggest a routine to catch and prevent entries so the user can be made aware the they are not acceptable?

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 have 2 comboboxes, textbox and a cmdbutton. When the user makes a selection in one combobox I want it to filter the choices in the second combobox. Then when the user clicks the button it passes the values from the comboboxes to a stored procedure and populates a datagridview. I am using VB.net 2005 and sql server 2005.

i have a form with a textbox, datagridview, tabcontrol. I use the tabcontrol to create an indexed view of the datagrid using the alphabet to filter the records to show the respected fields according what tab was selected. The textbox I have on the form is databinded to a field of a table in the database. The datagrid is also databinded to the same table in the database. The binding on the textbox breaks when I press on a tab to change the filter type. On the tabcontrol.selectedindex event I have this code to filter and fill the datagrid is: conn.Open()
