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).

Dynamically Make Image Invisible In Datagrid Without Change The Size Of The Cell

Aug 22, 2009

I have a datagrid where the first column is for image button for expand purpose. The visibility of the image depends on some conditions row by row. I am trying to handle this in ItemDataBound event, and using e.item.cell(0).findcontrol("imageButton").visible = false. The first cell of this row therefore disappears even that the size is specified in the ItemStyle tag.

VS 2008 Stop Textbox And Datagridview Cell From Scrolling (fixed Size)

Aug 16, 2011

I need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.

How can I stop the scrolling of the text inside the cell/textbox.

Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.

sample settings:
DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None
DataGridView1.AllowUserToResizeRows = False

WMI WIN32_DiskDrive.Size 5MB Smaller Than Win32DiskPartition.Size On The Same Disk?

Apr 8, 2012

Try it yourself: Plug in a USB flash drive (just a normal one with a single primary partition on it, as is the manufactures configured) to your computer.

Run WIM "Select * From Win32_DiskDrive"

Note the USB drive's size (in my case, it is a Kinston DataTraveller G3 2GB drive):

Win32_DiskDrive instance

Why the partition is bigger than the disk on which the partition is created and just a part of the disk?

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?

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.

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

Send Image Over Tcp, Image Size?

Mar 27, 2009

I'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?

Here's the client code

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)

I have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.

I tried:

picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)

But this just changed the the size of the whole picturebox, rather than the image within it.

Way To Change Image Size

Jan 21, 2011

I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:

- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)

I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.
