Moving To The Next Cell Down In The Datagridview Control?
Dec 8, 2009
I have a datagrid control on my form that receives data from a device on the COM port. I strip out the data I need and put it into the currently selected cell. When I load the grid, I find the first empty cell and set the focus so each load presents the user with an empty cell to start receiving data. Once I get the measurement, I need to move to the next cell down (like hitting enter in the grid). This will allow the user to do measurements with the external device without having to move to the next cell.

I have a datagridview and it has 8 columns as textboxcolumns. I am handling their cell validation with cellValidating event.
My question is that if cell validation fails for 3rd column of the datagridview then the focus should move from 3rd column to 1st column of the datagridview. How can i do this?
I have tried datagridview.column(0).selected = true, when validation for 3rd column fails, but this is not working. Focus still moves to the next cell. I can stop the focus to the current cell with e.cancel=true but i want it to move to the very first cell of the datagridview.

I am updating my last post so hopefully someone will help. I have following code that will move a cell to the next column when hitting the enter key while doing an edit. It will even check the row at the last cell to validate data is present.
However, if there is no data in a cell and I press enter, the focus moves to the next line like it normally does. I need to prevent the user from moving or clicking on any cell until the cell they are on has data in it. Here is the coe I have used[code]...

I wanted to implement the use of Enter key when entering data and moving from cell to cell. How am i going to implement that?
For example:
Text Box 1: Date: 02/02/2009
Text Box 2: Name:
then after entering the date on the text box i wanted to move to Text Box 2using only the Enter key.

I 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:

I followed an example to add a custom control (multicolumnCombobox) to my datagridview.[code]Ok, this is fine and dandy, for it adds the custom control to column 2 and row X of that loop.... Now, when I actually use the control for lets say row 0, how do I get the row 0 cell 2 value to be the same as the custom control??I have no way to communicate between the custom control and the datagridview cell.

I'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.
My code is:

I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.

I've followed the tutorial on the MSDN for this subject to the T and I'm not getting the User Control to Display in the cell.
I don't think the InitializeEditingControl is ever getting called by the Cell for some reason.
Here are my classes:
This is the actual User Control Class:

Public Class CustomCheckBoxUC

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.

how could I get the text of a specific cell in a DataGridView control ? If it matters , in my case , all the cells contain strings or nothing . For example , in order to get the text from the cell on row 2 and column 3 , what code do I have to use ? I have tried the Value property but seems that's not it . I've found some examples on the web ,but they were all for C# ... I guess , though , it has to be easy .

How to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.

Have this code so that when a checkbox in a column of my datagridview is checked, then the corresponding cell in column 2 (of the same row the check box is in) will turn blue with font color white.
[code]...
I'd also like to add a line so that as well as the cell going blue, the bottom border of the cell disappears, so cellborderstyle = none.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I have a DataGridView where Cell_Validating is being done. I have a Cancel button on my form that allows the user to exit out of the DataGridView changes. The problem is that if a cell was currently flagged as in error, I cannot exit and remove columns from the DataGridView. I get the following error: Operation did not succeed because the program cannot commit or quit a cell value change. Is there a way to cancel the validation once the focus has been removed from the DataGridView? Here is my Cell_Validating

I have a form created which an unbound datagridview that has three columns. "Position", "ID", "Name". The data is being added at runtime into a database upon the forms completion. (I don't want to add unnecessary rows to the database in the event a person clicks Cancel.) What I need to do is on the deletion of a row in the datagridview, search through the rows "Position" for a "HJ" value. If it's not found, change the "Position" value of the first row to be "HJ".

dg.CurrentCell = dg.Rows(x + 1).Cells(0)
At end of last record it show Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index + visual basic 2008

I need to determine which tab the user is coming from, and going to, when they switch tabs, and possibly cancel the switch. I have tried the Deselecting, Deselected, Selecting, Selected events, and all of them show the e.TabPageIndex to be the same as the sender.SelectedIndex.
Is there an event, or property, that I can use so that I can determine both sides of this, or do I have to hack something together with caching it from one event and using that value in the new event.
I am trying to avoid handling the Deselecting/Deselected events and caching the value to use in the Selecting event. I already know I can do this, so I am asking if there is a cleaner way, without doing this.
I have tried in both C# and VB, with the same results (no surprise).
