Set The AutoPopDelay For A Tooltip In A DataGridView Cell?
Aug 26, 2011
I 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?

I'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)

How can you show the tooltip for datagridview when cell is selected, not from mouseover but from using the arrow keys?

I 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

I'm adding a ToolTip to a ListViewItem. However, the ToolTip only shows up when the user hovers over the first cell in the row to which the ToolTip has been applied.[code]Any idea how I can make the ToolTip show up on a specific cell in a row, or even the entire row?

I 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 and hide the tooltip for error
Private Sub ChuteSinglesDataGridView_CellMouseMove(ByVal sender As Object, ByVal e As DataGridViewCellMouseEventArgs) Handles ChuteSinglesDataGridView.CellMouseMove
If cellInError.X = e.ColumnIndex AndAlso cellInError.Y = e.RowIndex Then
Dim cell As DataGridViewCell = ChuteSinglesDataGridView(e.ColumnIndex, e.RowIndex)

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)

I have an unbound data grid view. Every cell that has text will display ToolTipText for that value. I'd like certain cells to have no ToolTip and others to have a ToolTip that provides instruction on what the "X" button is for rather than just having "X" display. If anything, for this particular cell, I'd probably rather have no ToolTip. I've tried setting the ToolTip.Text ="" for the cell immediately after creating the row. On other cells, if I change the underlying text value, I try altering the displayed tip text, but only get the text value for that cell.
How can I remove/modify unwanted ToolTips in my DataGridView?

I have a datagridview that displays text from a cell in a tooltip when text is too long to be viewed in the cell itself. The default length of time, however, is not long enough for me to read all of it.
How can I make the tooltip display for a longer period of time?

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 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).
