Customizing The DatagridView - Navigating The Cursor Into A Particular Cell?
Jan 11, 2010
We are using the DataGridView Control for our projects. The Applications we are developing is the replacement for the Existing CLI (Command Line Interface Applications) written using FoxPro.The users are much more familiar with the Keyboard Navigations ratherthan using Mouse and all.Here What we need is, how can we handle the Keyboard Operations in the Data Grid View. Some of the Operations i am listing below.When we hit Enter Key :
1. Navigating the Cursor into a particular Cell (It will be in the Same Row, but Different Order), after getting focus the cell should become editable
2. Navigating the Cursor to the Next Row and First Column (Once i finished the editing in the Last Column )
3. Focusing the Cursor into a Specifc Row and a column. (With Editable)

I have second column as datagridviewTextBoxColumn column in the datagridview, after opening dot net form runtime, in first cell of this column , I am populating �-� character at third position with remaining everything blank. Requirement is cursor should be at first position in this cell.
But now what is happening is, as my second column�s first cell should have cursor after opening form, we are sending tab key from first column to second column runtime with SendKeys.Send("{TAB}") as result cursor is located after �-� which is not requirement , cursor should be at first position in cell.

I have a Datagrdiview control that is populated from values in a table. ie: One column would have a check box for weather a record has been processed using a Posted field as a boolean Check box. My problem as that I need this field to also show the results if the record is rejected or not. [B]I am trying to have the box unchecked if the record has not been posted. Checked if the record has been posted Or be Marked with a red X if the record has been rejected.The rejected field is of course in another column in the table.

I have set the datagridview.cellvalidating events. I want the user inputing in the cell and when error, the cursor cannot leave the cell when user key "TAB" or click in other where in the first time.But I find that it does not work in the first time. Until when I click the same cell in the second time, it trigger the action preventing user from leaving the cell and show the error message.

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)

how can I put the blinking cursor inside a specific cell on form load? I want the effect to be kind of like when you have a form with text boxes and when you set the tab order correctly, the first textbox will automatically have the focus and you can start typing right away. On a related question: how can I make the enter key activate the form's accept button when you're inside a 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 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 DataGridView control in my Windows Forms Application. I am adding rows to the grid using a background thread. I change the form's cursor to Waitcursor when the process starts and back to Default when it ends. This works well for the form, but not for the grid. When the form's cursor is changed back to default, the grid's cursor does not change, although the cursor over the rest of the form does.
I am updating the grid from a background thread? (The cursor is being changed from the UI thread directly). The background process raises an event, the handler checks the InvokeRequired property of the grid and decides if it needs to "Invoke" the method again from the main thread. So, in effect the actual UI update happens from the appropriate thread. I am not sure if this means that I am "using a background thread" or not.

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).

I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]

sample_form.rtf (1.48MB). Number of downloads: 36. I have a working form to give specific choices to the user and retrieve the user's choice. (See code below and attached image in WordPad file.) I know I can use a global ("Public") variable to pass the text of the three choices from the calling form to the called form, but is there a way to pass these from one form to the other exclusively? Of course, my main objective is to have as little memory being used as possible. I would like to make the form in my example (frmDialogChoice) a generic form that can display any set of three choices.
code within calling form:
Dim intSwitchToMake As Integer
Dim insFrmDialogChoice As New frmDialogChoice
insFrmDialogChoice.ShowDialog()

Trying to create a custom button to reside on the desktop at:
Me.Height = PictureBox1.Height
Me.Width = PictureBox1.Width
Me.Top = My.Computer.Screen.WorkingArea.Height - Me.Height
Me.Left = My.Computer.Screen.WorkingArea.Width - Me.Width
The trouble is all the arrows point to right, and the menus open variably depending on size.
Is there anyway to make the arrows point left and make all menus open to left in same direction?
Also, Is it possible to make the width of my form autoresize to the size of a label and the image box, while keeping the imagebox at the bottom right of the screen showing the populated label to the left?
