Link One Row Cell Across Multiple Columns?
Jun 4, 2010
I am making a application that manages room availability in a building.I have seen a similar function in another application that I'm trying to duplicate. I want to have a control, which I assume is the DataGridView that shows the room numbers on the left hand side, and then on the right it shows a box in that room numbers row for every day that the room is occupied. If it is occupied for more than one day, the box is joined.What control are they using? How do I link one row cell across multiple columns?

I have a DataGridView that has been dragged over from the DataSource Tab. All works good.I need to have the background color of some of the cells changed based on other columns in that same row. Such as, have the background color of a cell Red if the Status column (not shown) relates to 90 days overdue. The next row may be different.

I want to make a certain column of my datagridview red based on values from 2 other columns. I have a "HI" column, a "LOW" column and a "Result" Column which are all strings. Now I want to make the result column red if it's values is less than the "LOW" columns value or if it's value is greater than the "HI" columns value. I tried the following code but something is wrong because cells that shouldn't be red are red:
Private Sub dgvTests_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvTests.CellFormatting
If dgvTests.Columns(e.ColumnIndex).Name.Equals("Result") Then
Dim RowValue As DataRow = TestTable.Rows(dgvTests.CurrentRow.Index)

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?

Using Visual Basic,change the backcolor of the upper left header cell (.rows(-1).columns(-1)) of a DataGridView? I would like to use a different color to indicate to the user that he/she can right click a row or column header to access the Context Menu Strip. Not all of my DGVs use a CMS, so I would like to highlight its availability for the specific DGV.

I am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.

I have a bindingsource that is connected to a table where tho fields determine uniqueness. During a refresh I would like to return to the row that the user was on when he clicked the refresh button. BindingSource.find only supports one column in so far as i have been able to infer. So how doi do it. Altering the table is out of the question. Besides searching on multiple fields is a common event. Like for example first and lastname or perhaps company and journal number.

How can I set up my WPF datagrid to sort on multiple columns similar to having two sortable columns, clicking on the header of the first column for a primary sort and then SHIFT clicking on the header of the second column for a secondary sort. I would like the multiple column sort to happen automatically when the user clicks on the header of the first column without having to SHIFT click on the second column header. Is there a way to do this entirely in the xaml? If not how can I do this in the code behind? Currently using VB.Net but a C# snippet is acceptable if you have one.

I have 3 related tables in a DataSet - Customers, Products and Orders.I am trying to create an "editable" DataGridView which, ideally, will contain columns from all the tables. I have tried creating the joins in the TableAdapter SQL, but this results in a read-only data grid.
Customers and Orders are joined in a 1:M relationship by CUSTID.
Products and Orders are joined in a 1:M relationship by PRDID.
When the user adds a new Order record they will key the ORDERID, CUSTID, PRDID and QTY.I would like the DataGridView to display the related CUSNAM and PRDDES as soon as the user has keyed the Order record.The data must be displayed on a single data grid row. I am not interested in drill down or multiple data grids.My data looks like this:
Orders: ORDERID, CUSTID, PRDID, QTY
Products: PRDID, PRDDES
Customers: CUSTID, CUSNAM
The data grid should look like this:
ORDERID, CUSTID, CUSDES, PRDID, PRDDES, QTY
My SQL would look like this:
SELECT Orders.ORDERID, Orders.CUSTID, Customers.CUSNAME, Orders.PRDID, Products.PRDDES, Orders.QTY
FROM (ORDERS
INNER JOIN CUSTOMERS ON Orders.CUSTID = Customers.CUSTID)
INNER JOIN PRODUCTS ON Orders.PRDID = Products.PRDID;

I have put my business logic in a partial class as suggested in best practices. One of the conditions is that one of four fields of a row has have a value. Setting the errorprovider has no problems when creating a new row in the new row event. All the textboxes in the form show the error condition.
Dim ErrorString As String = "A value is needed for at least one of the " & vbCrLf & "Gallon, Fuel, Oil, or Misc fields"
e.Row.SetColumnError("Gallons", ErrorString)[code]....
The logic that sets them back to a no error condition though only sets the currently focused control in the form to no error. When the error is corrected.
MyFuelRow.SetColumnError("Gallons", "")
MyFuelRow.SetColumnError("FuelCost", "")[code]....
How can you reset multiple column errors at once?

Does anyone know how I can go about concatenating multiple columns from a table to populate into a combobox? I have 4 columns from which I need the data to show up in 1 line when clicking on the dropdown/combobox list. I'm not sure if I have to deal with the display member or the value member.

Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best way to go about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.

i just finally got my code, with the help of you guys, working to fetch column values from my database and display it in a ComboBox.
Now i am thinking to myself that simply displaying a customer's surname just is not enough due to repetitive issues etc. What i propose that i should do is have multiple column values in a the combo box. For example
CustomerID, Surname, Firstname
My current code is:
con = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:My DropboxDocumentsTaxi Service ProjectDatabaseTaxiProjectDatabase.accdb;")
con.Open()
