Jan 10, 2009I am working on my datagridview to get the current cell value from the column. I have three columns which I want to get the cell value from the second column.[code]...

View 7 RepliesI have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

So I've got 2 unbound datagridviews, and am providing a push/pull interface where the user can move records from one to the other.
Grid A is read-only and the selectionmode is set to FullRowSelect. Grid B has a read-only DataGridViewTextBoxCell, an editable DataGridViewComboBoxCell, and an editable DataGridViewComboBoxCell.
Because the grids have different columns, but represent the same records, my notion was to create the datagridviews with the same column structure but hiding certain columns, and then just move the DataGridViewRows back and forth between the two, which seams to work.
The problem is that if I go into column 2 or 3 in grid B, I get "Current cell cannot be set to an invisible cell".
I can select cells in column A and I'm fine. It should be noted that on grid B the hidden columns are 4-7.
I know there's a problem when the CurrentCell attribute is set to a hidden cell, but I'm clicking visible cells. I inserted a breakpoint on the CellClick event of the DGV, and again for column 1 that works fine, but on columns 2 and 3 it looks like the error is occuring before the event even gets fired.
Is something in the background setting CurrentCell to one of the hidden cells before firing the event?

View 18 RepliesI am using this code at the last line of my form load. I want the position 5,5 to have the cursor set at it. It works when then datagrid is already open:[code]However, when I use it on the form load, you can see that it was selected on the datagrid, but the cursor is set at textbox1...which happens to have the first tab order on the form, even though I have acceptstabs off. Can anyone tell me why this would happen? Basically, it is setting the cursor at the cell I want, but after the form loads, it jumps to textbox1 and highlights the text.
View 1 RepliesIn my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

View 4 RepliesI'm trying to use the errortext field on a cell to display a validation error. It works fine if I leave the cell, but I can't figure out how to display it while staying in the cell. I have seen examples where the code updates the row's errortext, but I really want to mark the cell in error.

View 1 RepliesI have a form with multiple datagridviews. On save the entire dataset will be serialized to a strongly typed property bound to a sql varbinary(max) Works fine. Of course the current "dirty" cell will not be saved as mentioned here :

My problem is the user could be coming from any one of 20 datagridviews when they click SAVE. Is there any way, short of checking for a dirty cell in each datagridview to commit any dirty cell before the save ( clicking another textbox control before the save does the trick but calling the focus() of that textbox prior to the save does not ) I was thinking perhaps catching the event of leaving the grid but it seems the base problem is clicking a button (for reasons I think I understand) does not fire lostfocus events for the current control and it doesn't seem the click handler args knows what the last current selected control is.
how can I create following thing with Visual basic?I would like my excel to check the date value in a cell and compare it to current date and if the value in the cell is older than 2 months compared to current date it would change the cell's colour.

View 11 RepliesI am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4.

Essentially what I'm trying to do is to save the value of a string() to a cell in the datagrid view. The problem is that when I close the program and reopen it the changed value isn't there... It's not saving properly.
Here is my code.
Dim BOCHURSTOTAL As Double = ((BochurimBindingSource.Current("Give_To_Bochur_Quant") * (bochurpr)) + _
(BochurimBindingSource.Current("Reg_Quant") * (regularpr)) + _
(BochurimBindingSource.Current("Priv1_Quant") * (private1pr)) + _
(BochurimBindingSource.Current("Priv2_Quant") * (private2pr)) + _
(BochurimBindingSource.Current("Priv3_Quant") * (private3pr)))
DataGridView1.CurrentRow.Cells("DGV1TotalColumn").Value = BOCHURSTOTAL
Me.Validate()
Me.BochurimBindingSource.EndEdit()

I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function. Checked it via a temp textbox i put on the form. What i actuall want to do is pass it back to another cell on the current row. Tried a few things but having no luck. Here's the code of what works. The name of the cell i'm trying to pass the result back to is called "BaseDec".

I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like
cell.value = string.substring(0,(whatever number I need it to be)).
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 was wondering the best method or code to Sum\total a bunch of cell values of an unbound column in a datagrid to a textbox string. this request is 100% genuine...im not some student trying to get you guys to finish my project, this is purely for educational and personal information for myself. im new to vb.net.

Is that possible to get current Enumerator (...or iterator? Don't know which tern is the correct one) in a LINQ query ?

View 1 Repliesin VB.NET DGVedit mode, after press ENTER to move the active cell into the desired cell, notdirectly move to the next line, how is it?
View 2 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
