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?
I want to display image next to the text in each row in a datagridview. I have searched the net in the past 1 hour, but no big success. I know, that I must override the cellpaint event, but how?
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?
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).
i'm using this code to display datagrid cell value in rich text box
Code
Dim rowtoselect = DataGridView1.CurrentRow rowtoselect.Selected = True rowtoselect.Cells(1).Selected = True
[Code].....
but i want to the richtexbox to display the cells 0 , 1 not only cell 1 i want the rich text box to display the whole cells of the row not just one cell of it
how could I get the text of a specific cell in a DataGridView control ? If it matters , in my case , all the cells contain strings or nothing . For example , in order to get the text from the cell on row 2 and column 3 , what code do I have to use ? I have tried the Value property but seems that's not it . I've found some examples on the web ,but they were all for C# ... I guess , though , it has to be easy .
I am using vb.net. I have following weird problems:If I comment DGVCusClient.Rows.Add(), the cell in ("column1",0) does not display data. But in debug, I can see that the first cell has data assigned.If I do not comment DGVCusClient.Rows.Add(), the cell in ("column1",0) displays its data correctly. However, it adds the row on the top for the first time. Except for the first row, it adds rows to the bottom as usual.
Dim i As Integer = DGVCusClient.CurrentRow.Index If Not ContainRecord(tempCusid, tempCltid) Then Dim i As Integer = DGVCusClient.CurrentRow.Index DGVCusClient.Item("Column1", i).Value = "a"
Since the results have some fields as NULL, I want to display a zero "0" wherever the value is null. I saw a single line of code yesterday on the forum which does the job, I'm unable to find it now though.
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)
does somebody know the user will be able to press enter within a datagridview cell without moving to the next cell. Also i want that the carriage return symbol, i mean a symbol that represents the new line , to be displayed.
I have a datagridview that is scrollable due to number of columns necessary.When I edit a cell, I display a multi-column listview that shows the item that will fill the cell in the first column and some form of description or other information in the second and sometimes third column (this should answer why I didn't use a combobox in the column in the first place).When I display the listview, when I scroll the datagridview, the listview stays put (as is the obvious). Is there a method to anchor, for want of whatever the proper term is, the listview object to the datagridview cell associated with it so when I scroll, the listview also moves? Or do you have to do calculations and adjust the positioning and repaint the object?
I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like
cell.value = string.substring(0,(whatever number I need it to be)).
I'm trying to make a visual map editor, and figured that a DataGridView would be the best way to go. 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.
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?
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 am new in VB2008. How I can programmtically delete/remove/clear the content of a cell of DataGridView? Say, for example, I have the following code that populates with data in DataGridView. Now,how can I clear/delete the "Test4" text from the cell of DataGridView? The GridView is not bound to any database.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim dt As New DataTable dt.Columns.Add("income") [Code] .....
Im doing a mini project and i need to display an image in picture box control when a cell clicked in datagrid view control .the image is linked through the database ms access and im using vb.net frame work.
So i have 1 form with 1 datagridview with many rows, and one picture box, i want to know how to select for exemplo the row number 2, and an image appear in picturebox, and if i select the row number 3, the image3 appear in the same picture box.
I'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String For Each dgvr As DataGridViewRow In myDataGridView.Rows customer_name= dgvr.Cells(2).Value '.... next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
i am developing an application with vb.net incorporating a Datagridview control. i know that we can make a particular column as checkbox column or text colum or button column. Is there any property/method to make one cell as checkbox cell, other as text cell and another as buttton cell for particular column within the DGVW?
Does anyone know how to highlight or change the color of text inside a datagridview cell? Not change the back or fore colors of the whole cell, but only for a particular word inside the cell. This is to make the search results more visible to the user.I tried doing it in the Cell_Formatting event of the datagridview but I'm only seeing options to change values of the entire cell (e.CellStyle). If there was only a way to select text inside the cell and set the selected text's properties. Or if I could use some formatting tags around the text.
At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp") InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred. By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:
[Code]...
Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?
I'm adding a textbox to my grid as follows and formating it as a date.But reagrdless it doesn't seem to want to format it as a date.Further how would I prevent, for just a single column, the user from entering anything but numbers and "/"'s?[code]
I am trying to do a blinking cell with red and yellow text in my data grid view. The cell may blink when certain condition meet.May I know how should I write the VB script in VB2008?
i have a column item-code, inside my database which i have bound to a datagrid view. The item-code comes in this format "A-B-C", i wish only to show the "B" part of the code, i have bound this column to the gridview and now wish to make it show the substring. I tried defaultcellstyle.format but don't know how to get a substring for it.
