In my datagridview you have to double click it (putting it into editing mode) in order to delete the contents of the cell. Is there a way to program it so i can delete the contents by just pressing the delete button when it is highlighted?
View 5 RepliesWhat i have: I have five Textboxs (1 to 5) I have a Button I have a Datagrid with five columns (1 to 5)What i want to do: on a button click put whatevers in the 5 textboxs in the specified columns create another row below and so on..
I don't know why its not a easy as:
DataGridView1.CurrentRow.Cells("Column1").Value = TextBox1
Etc, then create another row and repeat.
I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.
What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.
clearing cell contents within a DataGridView?I have a column with a list of names and would like to be able to make the whole column blank.I can currently achieve this (not the greatest) by clicking on individual cells and doing this ..
DataGridView1.CurrentCell.Value = " "
But rather than doing this I would like to be able to do every cell in the column, all at once. I'll put the code behind a button, so it can all be achieved by a single click.
I have a DGV I am working on, and I have many columns.
For example I have Columns colIsDayOff (Checkbox), colStartTime(Time), colEndTime(Time)
What I need to do is if when my DGV loads the data if colIsDayOff is checked, then make the value of the Start and End time columns blank, invisible, or something.
I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.
How can I delete a cell value in DataGridView?
View 3 RepliesI want to be able to delete records from my database and have this piece of code to do so:

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."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown

This is the code snippet posted on the site, anyway i tried various diffrent delete contents of a folder methods, but none could skip a file if it was in use or undeletable (but the reason is mostly due to it being in use)
I have a multi user application that stores temporary files in a folder that the users are using, but i want all unused temporary files deleted in it. So how do i go about doing this?

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.
