I have a datagridview that is bound to a datatable. When the form is displayed, the column headers have no sort glyphs and the columns will not sort.
I don't see a property on the form that controls column sorting - at least not one that's obvious. This is an area of the code that another developer wrote originally, so maybe there's something going on that I'm not aware of.
I'm trying to allow users to resize columns of my datagridview, but it's not working. I have this line:
DataGridView1.AllowUserToResizeColumns = True
I want users to be able to resize columns the same way they would if in excel.

I have an unbound datagridview with a whole bunch of columns.I need to sort based on 4 columns, the first three are simple strings, the fouth is a date string (which in itself presents a problem, since it wants to sort lexically but I need them in date order).
View 3 RepliesAll fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer. I haven't been able to figure out how to stop the designer from auto-adding all of the fields found within the bindingsource object.
View 6 RepliesI have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.

I have an application that converts one database to another and one of the functions I use is insert_Note below. This application has multipule threads all inserting diffrent data into the new database. The code below works for a number of inserts ranging between 24 and 120 but then fails with the error:There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.I you look at the code you will see that this cannot be the problem as the code works for some inserts but not all. What else can cause this error in a multithread applicationuld be welcome as I have spent three days on this and got no where!

There are plenty of SELECT (...) VALUES (...) statements and Parameters phrases to go with the VALUES. Those appear unhelpful to me as I have no form fields or datagrids and will be working with all the rows in a DataTable in a DataSet. Once started, this application will run to completion, writing as few as 10000 rows or as many as 250000 rows
My Task is to write out the contents of each specified DataColumn in the DataTable, one DataColumn at a time. The insert will also include the key columns and use the datetimestamp of the records as a criterion. Nulls in the specified columns are included.
My source is a DataTable, my target for the Insert is a "tall-skinny" table in an Access database. There is a smaller DataTable that is related to the source DataTable, if I was writing from within the AccDB I would use Joins. I have created a DataRelation, but have no idea how to use it in this context..
I have tried many different SQL statements but they all fail on Select. Here are snippets of the code:

View 3 RepliesI'm using the follow code to grab values when a row is selected on my datagridview:
Me.DataGridView1.CurrentRow.Cells(0).Value
in this case for the first column. I am doing this for several columns. What I would like to do is switch to specifying the columns by name so the code won't have to be changed if columns are moved around. I have tried several things that didn't work. Can anyone supply me with the code to retrieve the value of a column on a selected row by the name of the column?

View 2 RepliesI am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
