Binding A Single Column To A DataGridView?
Nov 24, 2009
In previous versions (VB.NET 2003) I would do
datagrid.datasource = dataset.tables(0)
datagrid.datamember = "Column1" 'Where this is the name of the column
This would show me just that column in the grid regardless of the number of columns in the dataset.
In VB.NET 2008 I do: datagridview1.datasource = dataset.tables(0)
I see all the columns.I then add:
datagridview1.datamember = "Column1" 'Where Column1 is the column name
I then have an empty grid.How does one get only a single column to show in the grid from a multi-column data source? I am using internal code to populate the datasets and tables.

With the DataGridView I'm used to just populate them with a list of some object, using the DataSource property. Now I want to just display properties from a single object, and I'm a bit confused on how to do it.. The object is updated through an API event, and I want to select some of the properties for displaying in the DataGridView, to look like this:.where "ValueX" is the name of the properties.Now, what would be my options for binding this to the DataGridView, such that property changes are automatically updated. Since an update also must invoke the control, does that mean I must reassign all bindings, or what logic is necessary in this case?
should I bind to an array, arrayList, stringList, dataTable etc? I guess I'm not sure which type of source will allow binding. Or if I should perhaps build the columns and cells of the grid and populate them "one-by-one" to the properties of the object?

I have two database tables in SQL Server Express 2008 with the following layouts.
DATA
-------
id
fundKey
amount
fiscalYear
FUNDS
-------
fundKey
fundDescription[code]....
These two tables are related on fiscalYear and fundKey. So if you were to look at the first line in the DATA table you would get:
1,General,2700,2008
I'm trying to create a front-end for this using VB2008. I thought a DataGridView (DGV) would work well for this. So I create a small app to test out my theory. I put a DGV on it and setup a data source to the DATA table using the designer and it works great. Then I change the fundKey column to be databound to the FUNDS column, looking up the fundDescription based on the fundKey. I also change it to a combobox column because in the future I would like other users to easily change the value. And all of this works well.My problem is in that combobox column, all the fund values are listed as options.So it lists: General, Indirect, General, Sponsored. I would like it to list only the values for the appropriate fiscal year. So if that row is for fiscalYear 2008, the fund options should be General and Indirect. And if it's 2009 the options should be General and Sponsored.What is the best way to do this? I thought about setting up views on the SQL Server side and having two datasets in the app and switching between them.

I have a datagridview with a datasource from a MySQL query. Works fine. However, I want to add an extra column and generate some data into the cells. This works fine too and shows up as intended. However, I cannot sort on that extra column and the contents of the cells in the column are cleared out if I sort on the other colums. I realize this is all because of the original datasource, but Im hoping there is a way to "connect" the extra column in somehow?
Grid_SearcherResults.DataSource = dbconnection.bSource
Grid_SearcherResults.Columns.Add("Location", "Location")
'Then some code to set the value of the cells in the new column.. etc

I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.
I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

I have a winforms app access a database with 6 tables. Out of 6, I am showing 3 tables on three different tabs on my Form. However, I want to do it using a single binding navigator that will use / change the respective binding source dynamically, depending on the tab that is activated by the user. I have separate binding source for each of the three tables.

What I'm looking to do is to update add a value to the given value already in the row. for instance:
id name value
1 peter 8
2 paul 10

I just want to add a specific value to each row, such as "8"
id name value

It 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?

I am working on DataEntry Forms in VB.NET There are two controls are having in a present window. One is Combobox and one is Textbox. Combobox values are Mobile, FAX, E-mail. By the mistake some one enter the values like , In the combobox-E-mail and in the Textbox-9987453434. Finally these are saved on the Database. But i want to Re Enter the values.
For this i was selected in the Combobox-Mobile and in the Textbox-9987453434. These are the right values i want to save on the database.
But here the problem is that Phone number column(Textbox) is Indexed. (Unique) or No Duplicates in the database. Now i want to update only one column which is coming from Combobox in the database.

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
