I am trying to load a DataGridView with a XML file. I got that part pretty easily. But I am having an issue with changing a column to an image column and then converting the text string to the image. This is how my xml is laid out.
[Code]...
But I cannot figure out how to change the 2nd column to in image column. I need to change the {3}{G}{G} to images. Each number and letter would be a different image.
I have a program in which I am doing a sql select on two tables with an outer join. In one option of my search I need to show all items in both tables so some items in the row will come back with a null value. I am familiar with using the DefaultCellStyle.NullValue = which works great when replacing Null values with the same value.
I am in need of replacing the null value in column 0 with the value in column 10. I think I am close but have not had any luck researching this on my own. Here is what I have.
dgvInventory.Columns(0).DefaultCellStyle.NullValue = CStr(dgvInventory.Item(10, ???).Value) if I replace the ??? with any value I get that rows data but all null values become the same, what can I do to tell it to replace the current rows column 0 with the current rows column 10 if column 0 is null.
I created a hangman game and It works well when I debug, but when I publish and place it on my son computer, when you guess a letter wrong it shows an error and says it can't find the images. I just it is something that I'm doing wrong but I don't know what. Some of the thing that I have tried is including the images in resources. I believe that it has something to do with the startup path, the path that the images are looking for does not exist. The installer installs the program in the programs file
Private Sub ShowPicture()
Dim strImagePath As String
strImagePath = Application.StartupPath & "imagesfig" & intNumWrongTries + 1 & ".gif"

I currently have a sql command that inserts info into a table through one of my statements. One of the tables columns is defined as an integer. The integer value inside that columns cell's is one that I would like to retrieve, and then set it to a value my enumeration (a string value) and later display on my datagridview.
The problem I am having is that when I retrieve the column's value from the table(let's say 1) I can't set the value of the rows cell to my enumeration type, it tells me the table holds integer values only and so I can't change it to text. How can I accomplish retrieving my integer value, setting it to my enumeration type (a string value) and displaying it in my datagridview in the same cell that the integer was?
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.

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."

i have a problem in locating bookmarks which are defined inside the table cell. Each table cell in my word document can contain multiple textboxes. I need to fill text in each of these textboxes using word automation. I tried placing bookmarks inside these textboxes for each cell and tried to replace using Word Automation. But unfortunately, i cant locate / replace the bookmark using the following lines:
cell.Range.Bookmarks.get_Item(ref oBookmark).Select(); //this is throwing exception as it couldnt find bookmark in cell.Range.Bookmarks list.cell.Application.Selection.InsertAfter("New Text");

View 1 RepliesI 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.

View 13 RepliesI seen some threads about export to Excel, but I tried all of it and nothing worked.I need to export the data on a DataGridView to an Excel (97 if it's possible or 2003 if not) sheet, using VB2010.
View 10 RepliesI would like for my datagridview to automatically fill in the column's next row with the previous entry + 1 letter. So say my datagrid is like this:
ID NextField
15-3A xxxxx
15-3B xxxxx
15-3C xxxxx
Everything is working fine if I type it in but would be nice if the user didn't have to type this each time and just have it fill in the next consecutive ID automatically when you press down to start a new row. Also i need it to work no matter what gets typed in... so if I make another ID 15-4A it will start filling in 15-4B etc. on each new row.
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

How can I change the value of one data grid view's cell? I am trying to change the displayed value of an integer (0-5) into one of my enumeration value.
i.e. the current cell displays 3 and I want to change the displayed 3 into the fourth value in my enumeration.
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).
When I add the first item in the datagridview its ok but when i add the second one it replace the last item being added.
here's my code
Private Sub add()
Dim i As Integer
For i = 0 To DataGridView1.Rows.Count - 1
