Show Tooltip When User Editing Cell In DataGridView
Nov 23, 2009I am trying to trigger a tool tip when a user enters a cell in a DataGridView and starts editing it. The idea being that I want the user to know to hit the Return key after they are finished typing in a string in the cell. I only want the tool tip to show when the user is editing a cell in columindex 1.
The following below does note seem to be working.
Private Sub dataGridView14_CellEnter(ByVal sender As Object, _
ByVal e As DataGridViewCellEventArgs) _
Handles DataGridView14.CellEnter
'Only care about columnIndex 1
If e.ColumnIndex = 1 Then

Apr 1, 2009I am working on implementing cell level error indication in my app and I have it set up to where it shows the error icon correctly and I tried using the datagridview FAQ sample code to show an errortooltip as well. I can watch as I set the errortooltip to have the proper data and display control (in mousemove event), yet the second I finish my mousemove event it fires the mouseleave event and resets my tooltip before the user ever has a chance to see it.
Here's my:

Show Image In Datagridview Cell Tooltip?
Oct 15, 2011I'm aware that the tooltip object can contain an image. I am unable to make an image popup when the mouse hovers over a datagridview cell, since it is not possible to attach a tooltip object to a cell ( myTip.SetToolTip(gridCell, "Hello") generates a compile error)

View 2 RepliesSet The AutoPopDelay For A Tooltip In A DataGridView Cell?
Aug 26, 2011I have a dataGridView that I programatically create where I want to set the toolTipText differently for each row by setting the toolTipText in the first column/cell of each row. I know I can do that by doing the following:
myDataGridView.Rows(n).Cells(0).ToolTipText = varContainingText
This works fine. However, it only displays for the default period of time (5 seconds I believe). I'd like to set the autoPopDelay but can't seem to figure out how. I can't seem to do something like:
myDataGridView.Rows(n).Cells(0).autoPopDelay = 10000
This is not a valid reference. How do I set the autoPopDelay for this?

View 4 RepliesC# - After Which Event Should Perform An Action After Editing A Cell In A DataGridView
Mar 24, 2010I have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.
DataGridView Cell Editing With Decimal/hexadecimal Formatting?
Jun 16, 2010I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF
Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value

Saving Value Of DataGridView Cell Before Editing For Undo Purpose
Sep 12, 2011I am adding an undo feature for a DataGridView using the Command Design Pattern. To create the EditCommand, I have to know what was the previous value of the cell, so I can re-enter it in case the user hits undo. I'm doing it using the CellBeginEdit and CellEndEdit events. With the CellBeginEdit, I save the value of the cell in a private variable and at the CellEndEdit function, I use the saved value to create the EditCommand. It's working fine, but I wonder if there is a more saner way to do it. Maybe a event that holds together the previous and the new cell value. Bonus points if I could actually prevent the DataGridView from updating itself and let the EditCommand do it.
View 1 RepliesUse A Custom Control For Editing The Contents Of A Cell In A DataGridView
Nov 30, 2011I 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.

View 12 RepliesBalloon Tooltip Info Icon?
Oct 18, 2009 I have a notifyicon in my VB.NET application. At the start of the programm it goes to the system tray and adds some global hotkeys. If one of this keys is pressed, then a balloon tooltip appears. At design time I have set up the balloon icon as 'Info'. But when the balloon tooltip appears, no 'Info' icon comes up, only the standard balloon tooltip. However, when the icon type is set up to 'Error' or 'Warning', it works. Why this behaviour? (on Vista)
An another problem is, that I set the timeout property f.i. to 500 milliseconds, the balloon tooltip is even visible after some seconds too.
Draw A Custom Icon Into A Tooltip?
Apr 4, 2010Not a single site anywhere, and I have even tried the MSDN, that details in any specific language how to draw a custom icon into a tooltip.
I have tried using every format of image I can produce, including (but not limited to) ICO, PNG, GIF, BMP, JPG etc... But every time, the app debugger clouts me round the head in defiance.. Windows Vista CAN do it.. and as in the image above.. StarDock figured it out..
I know your policy is to have the askee produce their code first, but the thing for me is
Also, I wonder if it would not be possible to take the code that does do the whole shabang, and compile it into a DLL or something that I can just embed for future projects - again this can be uploaded for others to refer to.

Balloon Backlog - Activating Notify Icon Tooltip?
Feb 9, 2010Every six minutes, my program talks to an instrument. Then, it activates a notify icon's tool tip for half a second to say what it did and when. According to the databases, everything's been going great, but the balloon tip text is a week behind and still trying to catch up. I'm getting text after text about stuff that happened last week. You should know that no one's touched the machine for at least a week. Because the program talks to the instrument every six minutes, the computer never hibernates, never shuts down, and the screen saver is off.
