I have a datagridview with data in it, i have set it so you can only select the row and one at a time.However, i need to get the data from one of the cells in the selected row, i have tried this
View 2 RepliesI've been looking everywhere for an answer to a simple question, but i'm having issues, so i thought i'd join and post here. I'm having issues with a simple concept. I load information from a SQL database, and i want to add a 'Passport' link URL relating to column cells called 'name'. It basically selects the name, and inserts it into the link fields to be opened. But i cant find a way to work it. I thought i could do it with something like:

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."

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 problem with selecting a row in a datagridview. I want the user to press on the data rowheader of the data gridview of a particular row and then that rows first item are put in a string. But the problem is that if i Select an item another item is still selected. So If I press the mouse button on the row header the previous item is still selected and then the wrong data is in the string. Here is the code under the event of the datagridview mouse click:

I have a datagridview that is bound to a dataview. I use a textbox to sort the list of data in the datagridview. Once the list is sorted I want to click on a row to populate the textboxes in order to update the data. Problem is once I sort the data I click on say row 3 and it pulls up the orginal data before the data was sorted in the datagrid view. For instance:
Before Sort:
1. betsy
2. james
3. john
After sort:
1. john
2. james
3. betsy
If I double click row 1 it will pull betsy info into my textboxes instead of john. I currently refresh my datagridview after every letter is entered into my textbox. I also reload my dataview and rebind the dataview with the datagridview.
I have a bound datagridview containing 4 columns. All I want to do is click on a row and then assign the value for each column to other controls (in this case textboxes). My problem is, I'm not sure which Event to use. I don't know how many events I've tried the code below in several different events but none of them are working.[code]
View 5 RepliesI try to select the last row like this:
Dim lastRow As Integer = DGV.RowCount
MsgBox(lastRow)
DGV.Rows(lastRow).Selected = True
The messagebox returns the correct number, but when it comes to select that row it says:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
But if I assign it a row, example: DGV.Rows(5).Selected = True
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 have a strange problem with a DataGridView I'm using which is bound to a table in VB.net
I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required.
However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time.
EDIT: I forgot to mention this is a Windows form, not an ASP.net application.
I have a DataGridView that is being populated. What I'm trying to accomplish is when I select like 3 rows I click a button and it gives me the "row numbers" for those three rows.

View 2 RepliesIs there a way to make a column unselectable? I can make the column read-only but it would be easier if it was unselectable so the user won't be confused trying to enter data into a read only cell. So if I clicked on a cell in that column or moved into that cell in that column it would jump to the next column, or not focus on the cell at all.
View 4 RepliesWith the two lists (t1s and t2s), I want to display t1s in a DataGridView, and in one column show the T2 property as a comboBox column, which dropdown will show the t2s list such that a new list instance can be selected. T2 has a Name property that should be used for displaying it in the comboBoxColumn.
I'm able to display the dropdown, but remaining a few problems:
1. How to display the correct comboBox "selection" on "load"?
2. How to change the T2 child object instance when combobox selection is made?
3. This is a really basic problem, which suddenly happened and I just couldn't understand what I have changed; The code marked BLUE now just shows empty cells.. While the AutoGenerated columns do show values.. Shouldn't those "manual" columns work?

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...

I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.

I have a datagridview and some code that will seek out the appropriate row and select it programmatic.
For intIndex As Integer = 0 To ofrmMasterList.dgvMasterList.Rows.Count - 1

The above code works like a charm, except that my selecting of the right row does not fire the datagridview 'selectionchanged' event like it would normally do if I just clicked on it manually.
what I need to do to get the grid to fire off this event after selecting a row with code instead of a mouse click?
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 wish to have a list selection inside a cell of it. like when the cursor is placed in a particular cell and the user hits 'Tab' button in keyboard a list of names & no should be listed and they have to select a particular name, click a particular row in the list form, which in turn needs to fill the cell with the name value.m
