VS 2005 Datagridview AllowUserToResizeColumns Not Working?
Aug 10, 2011I have some code written by another developer(no, really). The datagridview has the AllowUserToResizeColumns property set to true, but at runtime the grid will not allow column resizing. I've checked the code to see if the property is being set in code and I can't find anything. Is there some other grid property that, if set to a certain value, will disable column resizing?

Nov 8, 2011I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?

Update Not Working For Everything?
May 25, 2012I'm running Microsoft Visual Studio 2010 SP1 and SQL Server 2008 R2 and I'm using vb.net coding. Any other information that you need to know, just ask.I've got a form in a master/ details setup that has one table in details view in the top half of a split container, and another table in a dgv in the bottom half of the container. Everything is working well except for one value. My dueDate value always reverts back to the date set when the record was made, which is the default value put in when a new record is made. It doesn't give me any errors to work off of, and I've even went and coded the update by hand with this code:
Dim Num, Contract, ID, Receive, Due, Notes, Inspect, SO, PO, Entry As String
Num = Order_NumToolStripTextBox.Text
Contract = Order_ContractTextBox.Text
[code]....
All that happens when I hit save is my due date will revert back to the old due date. I have no clue what would/could cause this. I've went through to see if anything that would store the original dueDate (from a check I set up in my coding) is coded somewhere it shouldn't be, but all it does is make the check that something had changed while on the form. it takes an array of all my text boxes and checks it with an array made before leaving the form. Nowhere else is the original dueDate saved.

After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.
LINQ To SQL Update Not Working Correctly
May 11, 2009I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?

DataGridView Update Is Ok, Second Update Fails
Feb 13, 2011I am beginning to work with .NET technology after several years of VB6 and C++ and I want to learn as fast as possible.
My problem is with a DGV. It shows the prices of several store items, and I intend to let the user modify those prices by entering a % in a textbox (radio button states if that % is positive or negative) or by editing cell by cell manually.
As editing prices is kind of sensitive, what I do is loop through the DGV, add or substract the % engtered in the corresponding column and ask for a confirmation after whole DGV loop is done. If user agrees, DB is updated with new values. No problem here.
If user denies (in case he/she made a mistake), I restore grid's DataSource to a copy I made before calculating new percentages and this automatically refreshes my grid to its original state.
The issue is that if a user denies the operation for a 2nd time, this 2nd execution of the code fails at showing the original values, disabling the pseudo-rollback function.
Here is the code:

remember this works OK if user denis once. What am I missing regarding DataSources or its Tables? Is there anything like .Redraw?
