View 6 RepliesI have a DataGridView with cells from a database file that contains data. Basically, I want to get the text from the selected cells in the DataGridView and display it in a textbox at the click of the button. The code for the button click event is:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SelectedThings As String = DataGridView1.SelectedCells.ToString
TextBox1.Text = SelectedThings
End Sub
However in TextBox1 I get:
System.Windows.Forms.DataGridViewSelectedCellCollection

I would like to copy only the selected rows, but not all cells, only the ones I set in the sub, from one datagridview to another datagridview.

If MonthDGV.Rows(selectedRowIndices(0)).Cells(selectedColumnIndices(2)).Style.BackColor = Color.White Then but that is no use. As there could numerous selected cells all over the place, how would I check the BackColor of all the selected cells.
Ok I'm handling the RowPostPaint event so I can have the row's bounds so I can draw over that row in a custom manner.It looks good when it first loads, but as soon as I start scrolling, things get all wacky and aren't drawing.So when I first load the form, the grid looks like so:Looks good so far.But when I scroll to the bottom, it looks like this:It looks like the rows that aren't initially visible never get drawn, but don't even get drawn (the text anyways) even after the the row has been drawn.When I scroll back up to the top after this, it's looks like:Here is my RowPostPaint code, it's a little long but I tried to comment it so things wouldn't be too confusing.

I've a datagridview with a multiline textboxcolum, if the cell content is small (one line) the scroll works fine and I can see the content of all rows. But, if a row cell content is very large (ten lines), only is visible the top of the cell and if I try scroll down, the scroll goes to the next row without can see the rest of the cell text, even using the arrows for move inside the cell, the bottom is not visible.I was searching in the web and the only solution is use panel and put inside the datagridview. It looks me a fix more than a solution.
View 1 RepliesVB 2010 form has 1 panel, 1 DGV in the panel, 1 TabControl with 3 tabs in the panel each tab has a DGV all 4 bound to the same DataSet through code.
I have a form that has multiple Datagridviews on it, 1 in the main portion of a panel and the other 3 in a tabcontrol. If I click on cell 0,4 of DGV1 cell 0,4 of DGV2 is also "hilighted" and the same goes in the reverse order. If I click on cell 1,4 in DGV 1, cell 0,1 is hilighted in DGV2 (basically it stays with the last selected col and what ever row for that DGV).
This isn't the functionality I'm really looking for here, when I single click or change cells on any of the DGV's I don't want any of the others doing anything.
As you can see there are 2 cells selected this was created by a single click in the 4th cell of Param0
Is there anyway to turn on/off selected cells on a dbgrid. I know you can change the background color but I want all cells to lose "focus" completely as I think they are interfering with the visible property of the rows when I try and hide certain rows.

View 1 RepliesI have a DataGridView. I'd like the user to be able to select multiple cells using ctrl/shift. Then, as they type, I want the contents to update in all the selected cells. I'd prefer it if this happened as they type but I'd live with it updating the other selected cells when they leave the current cell.
I've tried hooking in to various events to to this but in each case there seems to be one problem or another that stops me doing it.

Is it possible to replace the selected NumericUpDown controls with ComboBoxes?
I understand that not all properties can be conserved but the only properties I need are the location and the size. The workflow I have in mind is as follows:
Select certain NumericUpDowns Click replace with... and then select ComboBoxes (or any other approach) Where the NumericUpDowns were, there are now ComboBoxes of the same size
The reason I want to do this is that I have to put together a GUI with multiple tabs. Each tab page has a list of Labels with either NumericUpDowns or ControlBoxes next to it. The order of the controls changes per tab. I just want to copy the items on the first tab and paste them on the other tabs. Then per tab I only have to change certain NumericUpDowns into ComboBoxes.
Replacing selected ONLY text in a string
View 3 RepliesI am selecting text using SelectText method in my string.I want to replace this text but only the selected area. When I use Replace method, it replaces all words in the string.

View 2 RepliesI am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.
i would like to know the syntax for this.i wanna add the values of 2 cells and then i will display their total in textbox.i have been trying to use datagridview.rows.cells but i cant just use it to add to cells values.
