hi Rod,

I have some questions

1. I want to shift the focus to the next cell or a particular cell in datagridview while i press the Enter key

2. Is there any way to color the entire row (which the currenct cell is on editing) (that too was temporary, while i left the row the color become tobe its original)

3. How can i remove a particular row

for now, that's all

thanks

and one more

how can i set the color of the editing cell . whatever i set the color of the current cell is changed to white while im in edit mode

thanks

an another one

how can i trace the text (which was typed by the user) - like in textbox's textchange. all i need is i want to know the each character - the user typed.

and the last one (!?)
when i was in edit mode, while i press the ENTER the focus shift to the below cell, i want to shift it to the adjacent cell, any tips?

thanks

When you are navigating in the control, intercept the KeyPress event. If the key is Return, select the next cell that you want and set e.Handled = True to tell the control not to process the Return key.

Unfortunately when you are editing a value, the DataGridView control doesn't have focus, the editing control (normally a DataGridViewTextBoxEditingControl--now that's a mouthful!) does so you cannot catch the Return key as easily. When you press Return, the editing control hides and focus moves to the next cell down.

To handle this, catch the EditingControlShowing event that occurs when the editing control is displayed and save the current row number. In the SelectionChanged event handler, restore the row if we were just editing. Here's an example:

> 2. Is there any way to color the entire row
> (which the currenct cell is on editing)

In the SelectionChanged event handler, set the current row's DefaultCellStyle property. If you want it to look just like the selected cell, set BackColor to SystemColors.Highlight and set ForeColor to SystemColors.HighlightText (although then the user won't be able to tell which column is selected). Here's an example:

> 3. How can i remove a particular row

Try using the Rows collection's Remove or RemoveAt method. See:

    http://www.vb-helper.com/howto_2005_...elete_row.html

> how can i set the color of the editing cell.

In the EditingControlShowing event handler, set e.Control.ForeColor and e.Control.BackColor. See:

    http://www.vb-helper.com/howto_2005_...ing_color.html

> how can i trace the text (which was typed by the user)

In the EditingControlShowing event handler, add an event handler to the editing control. See this example:

thanks Rod,

i ihave one more question

how can i find the caret position in a cell while editing. so that if the position is in first(0) i want to do some process.

thanks for the help

is there any to have a footer (like col-header)

Sorry but I don't know how to do either of these last two. I don't think the editing control has a SelectionChanged event to tell when the caret position has changed. You could poll it with a timer but it would not be very efficient and might miss something.

I also don't think the control provides a footer, although I think you can place labels below the control and line them up when the columns resize.

Hi Rod,

   I have similarly one problem while editing a grid. I want to process data when user press UP or DOWN arrow of keyboad. We can handle Left & Right arrow through your mention EditingControlShowing events but How can we handle UP & DOWN Arrow?

Thanks in advance...
Yogesh Shah

I think the DataGridView control automatically handles up and down arrows. Try it with this example:
