DataGridView Image Cell Losses Resolution If Cell Size Is Smaller Than The Image Size?

Apr 30, 2012

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).

Show Image In Datagridview Cell Tooltip?

Oct 15, 2011

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)

VS 2008 : Display Text And Image In DataGridView Cell?

Mar 24, 2010

My program parses chat room text. In the room there are smileys that get displayed. What I'm trying to do is parse out the image URL, download the image and put the smiley in the correct spot between the text of the message.I can do the parsing and downloading of the image into the datagridview but this only works of the column is set as an image column. Obviously due to the nature of the program I need to be able to put both text and images into the same cell. How can I do this?

DataGridView Cell Formatting To Display Image Based On Another Column Value?

May 7, 2012

I 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?

VS 2010 Click DataGridView Cell - Change Its Background Image

I would like to make it so that you can click one of many buttons to set which new image the grid cell will be set to when you click it. I've set up pretty much everything except that I can't figure out how to set the background image of the cell that I clicked.

How To Link Cell Value At Specific Location In The Datagridview Table To Image Source

Jan 13, 2012

As I have no idea on how to retrieve access data at the specific location in the table, so I wrote VBA code t export the entire access database to a datagridview which is located in the form1. There's a column of datagridview contain complete address information of a image. I'm thinking a way to link image source (of form 2 or xaml file) to the the column so that the image will be displayed. is there any code to get cell value at the specific location in the table? In excel VBA, sheets("Sheetname").Cells(rownumber, columnnumber).value is used to get the cell value, but how about code for this case?

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)

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.

Reading Cell Values In An Image?

Mar 10, 2011

I want to read the values of the 8 neighboring cells in an image as shown on the attached file. For example, the green cell is the home cell and it has 8 neighbors (cells from 1 to 8 as seen on the attached image). It will read all 8 neighboring cells then it will move one cell to right (now pixel 4 will be home pixel). Again it will read its neighboring cell values and then it will move to next pixel etc. It will continue till to the end (the last cell or pixel of the image).
