VB 2008 Link One Combobox To Another On Datagridview
Dec 10, 2009
I have a datagridview for the transactions table. On the datagridview there is a combobox column for the type id field in the transactions table. This combobox displays the transaction type name from the transaction types table and puts the transaction type id into the transactions table. That much is okay. But each transaction type belongs to one of several categories. I have a categories table. The category id field in the transaction type record points to the id of the categories table. The category id is not in the transactions table, it is in the transactions types table. I need to know how to link the categories combo box on the datagridview to the category id in the transactions types combobox, which isn't even there right now. At present the transaction types combobox does not display the category id. It displays the transactions type name. Do I need to add another combobox to link the categories combo to the types combo?
I need to have it first and foremost so it will display the correct category when existing records are pulled up. I think I could do this with a join to the transactions type table in the categories combobox. But that wouldn't cause the transaction type combo to filter by category when a new entry is made.
Can someone advise as to the correct way to link comboboxes in this type of heirarchy?
how to create a datagridview with the "main" datasource one table, and one column of this table it's a column (combobox) related with another table.I'm doing this all by code, but i have several doubts how to achieve this.First i had allready created the datatables in memory, the first one have only 3 fields (pk,info,size) the size field it's the field that's related to the the other table (id_size,size_text). Then i inserted the only roms that i need in the second table (dtUni)...In the previous steps i don't have any problem, but now if i try to add a constraint to relate the columns, something like this:VBdsTemp.Relations.Add("fkRel", dtAcess.Columns("id_size"),dtUni.Columns("size")) I get an error saying that the column doesn't exists in dtAcess.
I have tried searching on if it is capable to do autocomplete in a combobox in the datagridview control. I was planning to use the combobox in the grid itself. There is a property to set autocomplete true/false but I cannot get the cb to let me enter text to find. It only selects on the first character of items in the list.
I have a form with a DGV bound to a SQL database. the DB has three colums: ItemCode, ItemName, Status. The Itemcode field is a combobox complex binded (if this matters). How can I have the ItemName colum auto insert the text for the ItemName colum when I select the associated ItemCode with the combo box.
So i have a datagridview with two combos, when the form it's created i fill the first one with all the MainValues, and the second one with all possible values for the MainValues (called SecondValues) (1..N).Now my issue, when the user selects one value from the first combo i want to fill the second combo with all values related to the selected MainValue, i can do this for example by filling the datatable again with a parameter that filters the data, but if the previous rows have different main values, the dgv throws errors because it doesn't find the binded ones in the new filtered datatable.
How can i handle this? One datatable for each line?! Other thing, i'm using the SelectionChangeCommited event for handling the values change (in theEditingControlShowing), but if the user uses the keyboard to select the values the event doesn't behave in the same way or the way that i need. The values in the combo are numeric values (1001,1020,2010,3010), when the user select one of the values, i need to fill another cell in the same row with the number selected plus some string, example combo:1001 cell:1001XPTO. So if the user presses 1 in the keyboard the combobox selects the 1001 and fills the cell with 1001XPTO, but if i keep pressing the keyboard to select the 1020, by pressing 0 and 2, i get the 1020 selected in the combo, but the cell remains with the 1001XPTO.
I have a form with a DataGridView and ComboBox, both of which are populated with data from an Excel spreadsheet, the source is unbound. My problem is in repopulating the DataGridView with data from another worksheet in the same Excel file when the user selects the corresponding value from the ComboBox. For example if they were to select January from the ComboBox then the DataGridView would load in and display the data contained on say Sheet2, selecting February would load Sheet 3 and so on. I am running Visual Studio 2008.
I am working with an Unbound DataGridView. I would like to vary the contents of a second combobox based on what is selected in the first. I have code to add the columns and populate the first combobox, but I can't figure out how to do the second one since it can (and usually will) have a different list for each row AND the list must change when the selection in the first is changed.
I just spent over an hour looking up on the internet how to fill a combobox for each row in a datagridview that is unbound. I am adding the rows manually by code. The columns are already there and one of them is set to a combobox.
how to add two items to the combobox? Each row will have the same items available in the combobox.
I have a datagridview and a bindingsource. The first column is a comboboxcolumn which is bound to a table field and then the rest of the items are populated from another datatable. What I have on my other forms is a textbox called txtfilter and on the textchanged event I have this
Me.ProductBindingSource.Filter = "BatchNo LIKE '" & txtFilter.Text & "*'" that works great. Now I want to filter the combobox columns just like this.
How do I link my ComboBox (Which Contains Folders) to show the relevant files in my list view.
Dim myDir As New System.IO.DirectoryInfo(My.Settings.FolderPath) For Each myFol As System.IO.DirectoryInfo In myDir.GetDirectories("*.*") FoldersComboBox.Items.Add(myFol.Name)
I have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.
Also if there are 50 values in my combobox and 2 of them are: jacky, jacson When I type jac, I want the combobox to only give me the options starting with "jac"
Here is the code that I'm currently using: Dim dt As DataTable Dim dsNewDataset As New DataSet() Dim i = 0, intSetArray As Integer = 0 Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable [Code] .....
I have ComboBoxes and DatagridViews for which I've written code to automatically adjust the width of the ComboBox dropdown list or DataGridView columns depending upon the available space for them and certain conditions.The problem is when a vertical scrollbar appears. I then need to adjust for the width it takes, but am not able to find how to detect this using code.Ive been looking at .ScrollBars, but with this I can only set/get for them to be able to be there or not.
For the ComboBox:
-How can I detect if it has a vertical scrollbar before opening its dropdownlist, if at all possible?
-If not, how do I check using code if it has a vertical scrollbar?
For the DataGridView:
-How do I detect using code if it has a vertical scrollbar

I have 2 datagridviews on different tabs of a tabcontrol.The user can input names into datagridview1 column1.I want these names to automatically appear in datagridview2 column1, in such a way that when rows in datagridview1 are added and removed the same rows are added and removed in datagridview2.I also want the column sort function to effect datagridview2.
DataGridView TIPs has TextBoxes and ComboBoxes in it and the data comes from an SQL table. I see how to get or set the cell values that come from the ComboBoxes using Item, but how do I access the actual ComboBox events and properties?
figure out a way to link datagridviews to other controls like a combobox, list view or even another datagridviewBecause much of the code is managed by the IDE, I was expecting an IDE approach to linking controls. Is this the case or do I have to modify the generated code to do what I want.An example would be to use a combobox to limit the number of entries in a datagridview etc
I even have it set up so I can filter through the DataGridView by sorting though a specific company in the database. However, now I want to link specific cells from the DataGridView to other VB features such as a text box and check box. I am a bit lost as to the coding. In the DataGridView, there are numerous columns that contain a check box and I need them to correlate to actual check boxes I have in the form. I can do it through binding the check box on the form to the data source and it works but if I run a filter or sort through the company, the check boxes from the DataGridView no longer carry over to the actual check box on the page.
I would like to know how is it possible to link two datagridview control together. Say I have two dgv control on a form and anything I do on dgv1 will also modify the data on dgv2.
I have a datagridview and I have set the highlight property to full row, I also have a link column in my grid. my problem is, when I click on a row it get highlighted blue, but the link color is also blue so it becomes very hard to read. is there a way other than manually setting the cell forecolor to handle this issue?
How do I put a large amount of data (we are talking of a datatable with probably 50 columns and maybe 500 rows) from the access database that is bound to a datagridview in my program into textboxes depending on the row of the datagridview row I am clicking on.
What I have in the access database is countries and companies that are attached to several different dates to each company. these dates are supposed to be filled into the textboxes automatically when I click on the company row in the datagridview and also when i fill in a date in the textboxes it is to be written to the access database when I save the update.
I have used the below load code to fill my datagridview. Is there another way or can I use this?
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TCOMHRVT2TableAdapter.Fill(Me.TCOMHRVT2DataSet.TCOMHRVT2) End Sub
I successfully connected a remote MySQL database and it is listed in the Data Connections. My database has two tables, inventory and history, both work and I can retrieve the data from each.The problem is when I try to link the inventory table to a datagridview object. As soon as I enter the configuration wizard a red x appears in my data connections. Regardless of this, however, I can still successfully add my history table. The problem is that the inventory table name isn't visible and I get this error:<``>Could not retrieve schema information for table or view ``.The inventory table is what I need and I don't understand why it blanks out.
As I have no idea on how to retrieve access data at the specific location in the table, so I wrote VBA code t export the entire access database to a datagridview which is located in the form1. There's a column of datagridview contain complete address information of a image. I'm thinking a way to link image source (of form 2 or xaml file) to the the column so that the image will be displayed. is there any code to get cell value at the specific location in the table? In excel VBA, sheets("Sheetname").Cells(rownumber, columnnumber).value is used to get the cell value, but how about code for this case?
I just want to display data in a DataGridView (from SQL - already made the connection) based on what is selected in a ComboBox (data that is also coming from SQL). The 2 are separete on the form. I am using VB 2010.
This doesn't work for me: objCommand2.CommandText = "SELECT ProductID, Name, Color, Size, ListPrice FROM SalesLT.Product WHERE ProductCategoryID = " & cbCategory.SelectedValue
