View 1 RepliesI have been using this code to find the value of the cell in a datagrid view
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
MessageBox.Show(dgv.Item(0, eRow).Value)
This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
There is a DataGridView, I find I can only edit controllers of cells by column.I have set one column as Combox, but I want to change one of cells in this column as Button, and add then add left-click and right click event on this button.

View 7 RepliesHave 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."
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)

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 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

View 2 RepliesI wanted to create a module / tool similar to MS word where user should be able to add controls, resize controls, drag and drop controls.Anyway, I have got lot of references on how to resize control, drag and drop add control etc...my main requirement is i need a way to add grid and should be able to add cells to it. When i resize the grid control, the cell height & width should get extended and compressed accordingly. Also i need to save position of the controls to a text file.Saving positon of other controls is easy but most importantly i need to save each cell position of the grid.

View 1 RepliesOn my VB excel macro, I am trying to create a code to search a key word on a specific row and to display the adjuscent 5 cells values in a text box. That keyword will be repeated here and there on that same row. But the adjuscent 5 cells value will be differ each time when the keyword matches.
For example: Row 20 has a word "We gave" (key word) in cell D20. I want a textbox to display the values of E20, F20, G20, H20, I20 in a text box. Then on cell M20, there will be another "We Gave". Then it should keep the value that it displayed in the text box earlier and to show the newer values of N20, O20, P20, Q20, R20.
i have a column in datagridview composed of numeric as well as aphanumeric. What i want is when the user sorts the column, it will be sorted according to its number value, 1,2,3,4,5,6,7,8,9,10. However it my current module, the program sorts basing the first digit of the column. like 1,10,11,12,2,3,30,31.
i was thinking of converting the type to number so that it will be arrange properly, is this possible in the datagridview to covert type? because i saw only a readonly property celltype? i have also tried casting it in the sql query itself to INT but it did not work.
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");

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).
is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?
