Accessing Datagrid Selected Row's First Cell Value?
Feb 18, 2009
I would like some help for getting a value out of a selected row of a datagrid. I am beginning ti find out that it is not very intuitive in VB2003 which is what I have to program in.
after editing my cell in the datagrid . i am sorting then i select the next record the selection was do to the 1 cell on the row .i don't know what is the problem
The 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 have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:
I have searched alot but can only find info on moving entire rows bound between 2 datagrids, but noting on moving single cells. I have some code below that works ok from DGV to textboxes but not from DGV1 to DGV2.
Dim i As Integer i = DataGridView1.CurrentRow.Index Form3.DataGridView1.Item(1, i).Value = DataGridView1.Item(0, i).Value
How do I access the new value that a user has entered into a DataGridView cell? I've tried using the "e" parameter in several event types including CellLeave and each time I can only reference the old value.
I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.

I have a winforms application that uses a datagridview. When I access the EditedFormattedValue of a cell while it is in edit mode, sometimes, but not always, the whole cell turns black. Is this a feature of the datagridview, perhaps some sort of validation feature I need to turn off? Also, changing the background color doesn't remove the black background for me.
I've got a form with a FlowLayoutPanel (flpPhotos) containing several PictureBoxes that are created on-the-fly based on the photos in the specified directory. What I'm trying to do is right-click on any photo and select an option to delete that photo, view a larger version, etc. When I right-click on an image and select Delete in the PictureBox's ContextMenuStrip, I'm getting a NullReferenceException in the deletion method. When debugging, _selectedImg is Nothing, for reasons I don't understand, as a reference is saved to it in the selected PictureBox's MouseDown event. Incidentally, _selectedPB is also Nothing.
Private _selectedImg As String ' The file path of the image in the selected PictureBox Private _selectedPB As PictureBox ' The PictureBox whose ContextMenuStrip has been instantiated
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
I am creating a game with VB2005. On Form2 I have placed a textbox containing the Rules for the Game. When I click on Rules from the Menu in Form1, Form2 opens and displays the information, but the text is selected (highlighted blue) what have I done?
I am trying to get the cell value from a particular cell in a DataGridView table but am having a little problem with the syntax.My research suggests that I need to use the command:
DataGridView.Rows.Item("Index of Row").Cells.Item("Name of Column").CellValue but when I create the command: x = DataGridView1.Rows.Item(0).Cells.Item("Dec").CellValue
I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
am converting a old vb.net program to WPF and am having trouble. I imported some data to a datatable and dumped that into a datagrid. I now need to go row by row and extract the cell values and use them to update the appropriate database record. This was working in my old program using:
For i = 0 To DataGridView1.Rows.Count - 1 cellvalue = Me.datagrid.Items(i).Cells(8).Value).ToString (insert to database) etc
