How do i make sure that the changes "done" by a user interacting with a DataRepeater control are reflected in the corresponding database source table? I have used DataRepeater in VirtualMode, do I have to supply my own code that will "actually" make corresponding changes to the actual tables, or is there a way of "configuring" or "binding" the controls on the DataRepeater to the "dataSet" so that the changes made by the user are reflected automatically in the underlying table? Whatever I have tried so far has yielded no results; whenever i edit the data on the control, the actual data is not updated. I attach a file showing the only events under which i have put some code: Load event of the Windows form, and the ItemValueNeeded event of the Repeater Control.

View 29 RepliesI have two Datagridviews, Datagridview1 populates from and excel workbook the user selects. After that the user does a verification on the data. The Requirement I have is for the two grids to mark any records in yellow that are the same so the user knows what needs to be done.
I did the code to match the Cell Contents as there was no other way.Datagridview2 is the sartting point, the value in colum 9 is what needs to be found in Datagridview1 so i loop through the rows, colums by column, It finds the first lot and marks them yellow but then stops with the error. It does not run through all the entries.
My Sample code:'Button click event calls te public sub Datagridview2RowCounter
'Declare Current row position of grid 2
Dim Datagridview2CurrentRow as integer
'What text it should find and mark
Dim BookData as string
[Code]...
This is basicaly what i did but it stops after the 7th or so time it passes through all the code. I have more that 3500 rows of data to verify each time the workbook is opend, that is why i need to mark the Cells in yellow so i know what has been done.im stuck, everything works fine in the whole app, from importing data from excel into datagridview to the marking of other fields for some other reason, This is the ons that does not want to work.
i tried getting rid of a few "dim msearch as new" etc. which is what the error msg comes up with. but it just keeps making it worse.[code...]

View 6 RepliesI am writing a serial application using VB .net Framework V4 , where I use a background worker to Read a file and send it to a serial port using SerialPort1.writeLine method. The BackgroundWorker1.ProgressChanged Event handler sub Updates the Line Number to a TextLabel and adds each line sent to a RichTextBox using RichTextBox1.AppendText() method on main form (Form1).
The problem arises at 115200 Bauds (and higher),may be because now the text is updated real fast on the form an unhandled Exception in BackgroundWorker1.ProgressChanged Event handler sub occurs. Otherwise at lower baudrates ex: 9600,19200 etc. Application Runs Perfectly Fine.

I am getting a stack overflow exception during the process of my program. yes I have used recursion method in my application and can't see any other logic to get the data. Scenerio is I need to present the data in the grid as BatchNo|Parent|Date|Qty|Cost columns. I have stock history and old stockhistory table(17 million records).

I am Using Visual Studio 2008 Express edition (.NET Framework 3.5) ... I got this Error when Using A recursive Call To a Function .. I have 3 Background Workers Which Select Data From Database With Status =0 , Take The file Name And File Path Asssosiated With That record, and Then Copy it to other place and on successful completion update the status to 2 otherwise to 3 . and again searech for other record having Status 0 and so on ..
i made a method for selection of record from database every worker call this function . Now I have a check when dataset is filled i checked is there any row ? if yes then it do the rest of work otherwise agin call it self to search for the record...ECURSION.. In Case of records with status zero , It works Fine But in Case of no records Which have status zero it recursively calls itself For approx 1.5 mints and then throws The Exception That " System.StackOverflowException occured in mscorlib.dll at line "DataAdapter.Fill(Dataset,Table)" . I have no Idea what to do with this ..
Eventhough I have Encloesd It in Try...Catch Blocks but It didnt Cath It .. I serached The Internet and msdn social help for it and i found that it occurs most with infiniteloop or Infinite Recursive calls. i know it is due to my recursive call to the SelectData Function But i have no option without it?And One thing more that this project i mean the exe of this project is concurrently runs with another project Which add data to the databse about Filename Filepath and status =0 for Fresh entry..
I am working on a multi-form code. For some reason, this randomly began happening just about the time I finished my code. The intial form loads just fine, but when I go to click on any of the selected buttons, the code crashes. and I get an unhandled exception of type 'System.stackoverflowexception' occured. Does anyone have any ideas? I have checked for any subs calling subs that call subs and I don't have anything of that nature. It is breaking at the point that is bolded and underlined.

View 3 RepliesI am having some trouble getting some code to work. Here it is:
[Code]...
Using the walkthrough from [URL], I implemented a DatagridView in virtual mode, totally unbound, in VB 10 Express (we are talking WinForms).
I understand that CommitEdit (DataGridViewDataErrorContexts.Commit) commits the current cell's contents to the data cache.
The example uses row-level commit, i.e. it pushes the values into a row buffer until the current row is left. Only then the row is added to (or updated in) the data store. That's exactly what I do, too.
Question -- how can I commit the current row programmatically without leaving it? (I want to commit the whole row, not just the current cell.)
If the user leaves the row, there is a RowValidating, RowValidated, RowEnter event sequence where the datastore update is taken care of. So one idea (currently my only one) was to simply re-set CurrentCell to Nothing, for example.
But I cannot just set the DataGridView's CurrentCell property to Nothing (or any cell outside of the current row) since I want to commit from within an event handler of a custom edit control created by a custom column, and I see an System.InvalidOperationException exception when setting CurrentCell there.
In fact, it is a tiny button right to a combo box, i.e. I create a DataGridViewComboBoxCell descendant which is a DataGridViewComboBoxColumn descendant's edit control. My special ComboBox cell adds a tiny button which should commit the current row. Unfortunately, that button's _Click event handler cannot change CurrentCell since DetachEditingControl throws the exception then.
Obviously, I must delay the CurrentCell re-assignment until the whole _Click event has been processed. Or what? How would I do that -- register a custom Windows message, SendMessage that one to me, and override the windows procedure of the form so it re-sets CurrentCell when this message is received? (Hello?)
There should be a rather easy way to let DataGridView commit all changes by firing the events that I handle to perform the datastore update, no?
I'm trying to create a toolstrip using the system render mode, but the split button control doesn't look right in Windows 7 It's almost like the drop down button is offset to the right by 1 pixel, or part of the border is missing.

View 5 RepliesThis should be something simple, but I just cant make it work. I have a DataGridView with a "Technician" column that I would like to have a dropdown box, allowing the user to select and assign that row to X technician. It works, however with the default edit mode, you have to click the box THREE times to get the dropdown. If the edit mode is changed to "Edit On Enter", it works FIRST click, but this ruins the way I want some of my other columns to work.
Questions:
1. Can I enable/disable editing of ONLY certain columns?
2. Can I set the edit mode for ONE column?
3. My "Unassigned" section (the last line) no longer works after adding my "With" section to add my combobox. I thought the "DataPropertyName" would allow this to work. Whats the deal?
4. Can I edit the visual style of the combo box? It does not match AT ALL
[Code]...
When the cell is selected but not open for editing a right click will open the ContextMenu. If the cell is open in edit mode a differnt list is displayed (cut, copy, paste, etc.). Is there a way to append the ContextMenu to this menu or turn that menu off and use the ContextMenu?
View 4 RepliesI have a DataGridView in which one column has data that the user needs to align by adding spaces. For example, the first two rows might contain:
kumbu
kuimbiu
And the user needs to be able to line up the letters that match by adding spaces. Something like this:
ku mb u
kuimbiu
Now in order to do that with the DataGridView, the user must enter edit mode in the top cell, add spaces, hit enter, re-enter edit mode in the bottom cell, and then add spaces. Our users would like to be able to, while in edit mode in the top cell, hit the down arrow and advance to the second cell while staying in edit mode, saving clicks or F2 hits.
Is there a good way to do this? I have tried trapping the down arrow key press, leaving edit mode, advancing a cell, and then entering edit mode with the grid's BeginEdit method, but this does not do what I want.
