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.
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 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.
in one of my datagridview controls , All the cells of a single column can have any one of the following controls :
textbox
LinkButton
Combobox

I have a bunch of columns in a datagrid view (date, transaction type, amount).If the amount in a row is '150.00', I want to make that cell red.I made a Private Sub and run this after the datagridview is filled.
Private Sub ColorCells()
Dim ColumnCount As Integer
ColumnCount = dgvLedger.ColumnCount - 1[code].....
However it seems to have two bugs. When it is first run the first time when the form is loaded, it doesn't put the rows with 150.00 in it in red.If I have a button on the form and set it to run this Private Sub, then it runs through it again and will color the ones in 150 as red.If I resort the datagridview by clicking on a column, they all return to green again, and it looses the formatting.

In DGV, if the contents of the cell is truncated, the DGV shows ellipses (three dots) (...); but as the font is set to a Gujarati font, it displays a Gujarati alphabet "ઈઈઈ" instead of "..." because the Gujarati character "ઈ" is coded with the English "." (dot) character.In Gujarati font, "." can be generated with the English character "P".So, How can I change the ellipses to English "P" character? OR How can I remove the ellipses completely?I have found a similar solution by berc on Tuesday, August 31, 2010 1:33 PM :but I am not sure it is the perfect and/or the only way to do so, AND it will really work or not
