I have a datagridview control on a form that is filled programatically (dataadapter, dataset ) from a database table (access).
Some of the columns in this table are foreign keys to other tables. Is it possible to have these
columns as combo box columns so the values can be selected directly from the other tables?
in item Search form i can search the item that i want, if i found the item that i need i will select the entire row and fill this row in DataGridView in frmSWSfromGrid.i been able to achieved this same scenario but it uses textboxes.the ff. COde

I've been trying to use lookup tables to display names instead of ID's in a DataGridView using a DataGridComboBoxColumn and have even copied the example shown in the Forms over Data videos produced by Microsoft but still get the following error message:System. =Argument Exception:DataGridView ComboBoxCell value is not valid..Everything was done in the designer and the problem only occurs with the DataGridView; lookups work fine using a combo box when displaying single records.Also the error message only pops up when I close the form. Prior to that all the names are displayed correctly for each record, the drop down list shows the names correctly and I can edit, add and delete rows and save all my edits with no problems. Its just when I close the form that the problem occurs.Each time I press OK in the message box the names in the combo boxes are removed, one by one.
View 5 Repliesi have a master detail form with databound datagridviews.my detail datagridview is bound to FKFieldSubFieldLookupTableBindingSource and it shows the linked sub-fields when the main field changes. This datagrid has only one column which is the sub-field names column. this column type is ComboBox.here are this combobox details
DataSource = subFieldLookupBindingSource
DisplayMember = sub_field_name
value Member = sub_field_id
No Problem until here.When i click on the Cell combobox I get the list of all the sub-fields. I don't want this. because once a sub-field has been associated with a Master field, it should not be available for other Master fields.What i did was, In the SubFieldLookup Dataset, i added a query to get all those sub-fields which haven't been associated yet.but this clears up the detail datagrid and shows blank comboboxes where it is supposed to have the sub-fields.
I simplly want the master-detail mechanism to work and when i want to add a new sub-field, and click the combobox in sub-fields datagrid, i want to have only those sub-fields which are marked False in database in the column 'alreadyAssociated'.

How to add a checkbox column at first column of datagridview including column header?After adding, how to code to "check all" or "uncheck all"?
View 27 RepliesAdd persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

I have:
- Table1 with columns: PK_ID1, LOCATION, DIRECTOR, SELLER, SELLERID, WORKTIME (relationship), WORKCODE
- Table2 with columns: PK_ID2, WORKCODE (relationship) & WORK_DESCRIPTION
My DataGridView do a SELECT * FROM Table1;How can I replace WORKCODE with WORK_DESCRIPTION in DataGridView, please?
Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
Is there a way to find the column index of a datagridview column using the columns DataPropertyName?I currently use a loop (shown below in the class) which is kind of ugly, but it works. I'd like to do something like this, which seems more elegant.My goal is this, I store the users DataGridView column settings (i.e. DisplayIndex, Visible, & Width).When the user opens the form that contains the datagridview I want to get those settings from the database and apply the settings to the datagridview.[code]
View 5 RepliesI have a data gridview on my windows form with 4 columns. Now I identify a column as followed:

View 17 RepliesI have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?

i am using the LookupEdit control from DevExpress fairly heavily in my projects. It is like a combobox, but it is bound to a datasource and can display multiple columns from the datasource. A single column is identified as the "value" column and a single column is identified as the "Display" column.
I use the LookupEdit control on my forms to give users a pick-list of appropriate values for a particulat database field. Each field has its own table in the database holding said values, commonly referred to as a lookup table, and each lookup table is used as the datasource for each paired LookupEdit control. Of course when a form is being filled-in by the user this works great. And it works good when the user opens a saved record into the form and I set the EditValue of the LookupEdit based on the value stored in the database. Pretty basic stuff right?
Now here is the problem... Let's say a lookup value is no longer an appropriate entry and so it is removed from the lookup table. Say I sell cars and one of the fields in the Cars table is Color. And I have a lookup table called CarColors and the selections are: Black, White, Red, and Silver. Now let's say we sold some Red cars in the past, but now we no longer carry Red as an option and we probably never will. So I remove "Red" from my lookup table, and now when I load an old Order into my form the LookupEdit for Car Color value now shows NULL. What is the best way to handle this situation? ProcessNewValue? Set NullText property? Use a bit field in my lookup table for IsActive, and set to FALSE for Red instead of deleting it?
Obviuosly I want to retain the historical values while maintaining a currently valid lookup list. And I know this question goes deeper as there are probably database design considerations like whether or not to put a constraint on the foreign key relationship between the lookup and child table, etc... I should also mentioin I am using LookupEdit control rather than a ComboBox becasue a lot of my lookups have other information like Description, Sort Order, or are coded and thus require a multiple column display.
I have an Access 2003/2007 application that pulls computer names from my network along with their last know TCPIP address. This data is created by another application. I am trying to use the IP Adresses to install software via a push application that accepts a list of IP Addresses.My app has a history table of every comuter that has been checked to see if the software is installed. I use the Fully Qualified Domain Name to make this verification. I then populate my text file with the IP address of the computers that have not been installed.This all works well if the last know IP address is still valid for that computer.What I am trying to find is a function that I can pass the FQDN to and have it do a NetBios lookup to return the current IP Address from our DNS Servers so I can be sure that the IP addresses I am populating the text file with match the FQDNs of the computers I am trying to push the software to.I found some info on System.Managment.dll. For some reason Access will not let me add it to my library references.Does anyone know of a standard library function I can use to achive this.[code]

I am converting a DTS update lookup to an SSIS lookup with an update query. So far it doesn't seem to work.

In SSIS:

I am almost finished building my application. All the data need is being inputted from various locations. I have a form that is suppose to consolidate all this data into a specific format. There are 47 fields that have to be populated and/or calculated based on two fields, the Username and a date range (this part is done). I was trying to set each of the TextBoxes equal to the SQLCommand that would return the proper value, but i am not calling it correctly. Would somebody please take look, is there something i am missing, do i need to write it in a function? I have had to use the Select statement itself in a couple of filters so I'm pretty sure that is correct, but i need help getting it to run the sqlcommand.[code]
