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)

View 2 RepliesI 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.

How do I show the error icon and ToolTip when the user is editing the cell in dataGridView?
View 8 RepliesI 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 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).

View 4 RepliesI have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?

In excel VBA, sheets("Sheetname").Cells(rownumber, columnnumber).value is used to get the cell value, but how about code for this case?

View 1 RepliesI 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.

View 1 RepliesI have a small application in which I need to show alerts if a particular condition is met. I have an mdi form and several child forms. Now the best way to show an alert is to show a tooltip on the right side corner of my mdi form. Though this works, but the problem is I want user to close the tooltip once he has read. Now the tooltip that vb.net provide does not support click events. If I give a long time duration the tooltip would be open all the time and if I give a short duration then it will close quickly. What can I do ?

Is there something I am missing or do I just need to create my own MouseEnter event?
