Make DataGridView TextBox Cell A ComboBox Cell When It Has Focus

Dec 23, 2011

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)

Nov 7, 2009

I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.

I have tryed :

DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect
DataGridView1.CurrentCell = DataGridView1.Item(4, e.RowIndex)

DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells(4)

And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

IDE :: Force The Cell Value To Be Blank And Focus Back On That Particular Cell And Try Again?

Jul 28, 2010

Datagridview . in cell validated handler and I have the column,row for the cell that I just checked on.  If the cell contents are bad, I want to force the cell value to be blank and focus back on that particular cell and try again.The code i've tried simply moves to the next cell in the grid instead of staying where I want it to be.  Surely there is a command to focus and put the 'cursor' back in a particular cell.Some sample code I'm working with:

If Not datagridview_TagAssignment.CurrentRow Is Nothing Then
[Code] .....

I am always ending up on row(0) and never the row I right clicked on.

If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex >= 0 Then

Setting Focus In A DataGridView's Cell?

Mar 16, 2010

I am trying to set the focus in a datagridview's cell after the user enters some data and tries to tab out of the cell. I can't seem to get the focus in the cell they just edited. I can change the background color, but the focus goes to the next field in the grid. I am trying to do this in the _CellValidating event. Here is my code :

Private Sub dgvFish_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvFish.CellValidating

[Code]....

The function CheckSampleNumber() takes the value of the cell just entered, and checks to see if it has been entered either in the current grid, OR in the database.

Setting The Focus To A Particular Cell In Datagridview?

Mar 11, 2009

I am having trouble setting the focus to a particular cell in datagridview.

I have a timetable and on initialisation of the program, it compares the time in the datagridview with the current time. If the time has passed, the row is displayed in grey, if not then it is shown in black. I then want to scroll through the datagridview to focus on the first black line.

Here is the

"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" with the note about infinite recursion.

What have I done wrong and how do I scroll through to automatically set the focus?

I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really).

Custom Control And Datagridview ComboBox Cell Back Color

Jun 5, 2009

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.

In DataGridView, Moving From One Cell To Other Cell

Mar 2, 2009

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.

TextBox Connection To Datagridview Cell Or Database?

Aug 16, 2009

I have two forms in my program,on Form1 there's DataGridView and it shows the content of my database,on my Form2 there's few textboxes and listboxes. Wen you select row on Form1.DataGridView and double click the row header it pops up Form2 and shows the info of that previously selected row in those textboxes and listboxes.

Now with some help,i've managed to understand how to do that,but how to make those textboxes and listboxes connected to that row also?
I mean when i enter something in textbox it brings back the value to corresponding cell(to that cell of which value was shown in the textbox). Or how to make that textbox connected to the same row directly in my database itself(probably worse scenario,since any time i type new vallue and hit enter ir will connect to database,other way the value in DataSource will only be changed,it would take less resources and time probably?)

I need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.

How can I stop the scrolling of the text inside the cell/textbox.

Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.

sample settings:
DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None
DataGridView1.AllowUserToResizeRows = False
