View 1 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."

View 5 RepliesI was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?

I handle the validation in the CellValidating event, and if the cell is invalid display an error message, then cancel the exit of edit mode. However I would also like to erase the content of the cell currently in edit mode.

I have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.
I have a comboboxcolumn in a DataGridView. I have loaded int with string data that appears in the dropdown box. I have added an event to it for an SelectedIndexChanged. What I am trying to do is autosize the width of the cell in the column based on the string chosen in the drop-down box within this SelectedIndexChanged event. This seems to work but it does not work off the initial selection change. When I select the desired string in the dropdown box the width of the cell does not autosize. I am not sure why.
I was trying to get around this by wrapping an IF stmt around the autosize logic by saying if cell value = "" then cell.width = Max Width of all loaded strings/ However, I can't figure out how to access the string array loaded into the dropdown list

I also have a bunch of event handlers set up for each item in the context menu.

is it possible to raise EditingcontrolShowing event when we try to change the value of a combobox cell in datagridview
[Code]...
I'm afraid this is a very simple question, but I can't figure it out... I hardly ever use the DataGridView (usually use a third party grid) so I never needed to do this before.Anyway, I have a DataGridView that is data-bound to a List(Of SomeClass). The grid is not ReadOnly, but I made every column ReadOnly except the very first, which is a boolean column so it displays a checkbox. This way, the user cannot edit any cell value, but he can check/uncheck the checkbox in the first column.
What I need now basically is an event that is raised when the user (not programmatically) changes the value of this checkbox. I also need to be able to retrieve the bound item from that event (from the row number I think?) but that should be no problem, I hope.Anyway, there's a bunch of events that looked promising but all have something I don't want:
1. CellBeginEdit - Fires before the checkbox value has changed, so can't use this.
2. CellEndEdit - Only fires after the edited row loses focus. I want to save it back to the database as soon as the user changes the checkbox value!
3. CellValueChanged - Same problem as nr 2.
I'm sure it must be possible for me to react as soon as the user changes the value of the checkbox? How can I do this?
I have a Datagridview called DgvReturns. which contains two fields,
1) Yes - checkbox (boolean)and
2) Received Date - textbox (DateTime)..
What I want to do at run time is that when a user Checks the Yes checkbox Received Date is populated with the current Datetime.
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.

View 2 RepliesI 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).
in VB.NET DGVedit mode, after press ENTER to move the active cell into the desired cell, notdirectly move to the next line, how is it?
View 2 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.
