How to prevent DataGrid cell editing ?

[Guest]

I have a DataGrid on my Form, and I wish to disable any cell editing.
For example; when the user clicks on a cell, the cell become editable by
changing its color to gray and context menu is shown on muse right mouse
click.
I do not want the enable this cell context menu (I have my own context menu)
and I do not want the cell to change it's color. I want that on any click -
the entire row will be selected.
There are some other cases where the cell become editable, and I want to
prevent them all.
I did not find any event that I can hook to for that.

Can any guru in here tell how to prevent any kind of cell editing in the
DataGrid?

Hi Sharon,

I think most of your problems could be resolved by George Shepherd's
Windows Forms FAQ:
http://www.syncfusion.com/FAQ/WindowsForms/FAQ_c44c.aspx

The corresponding items is as the following ones:

5.7 How do I prevent a click into the grid highlighting a cell?

5.11 How can I select the entire row when the user clicks on a cell in the
row?

5.18 How can I prevent a particular cell from being editable?

5.41 How can I make my grid never have an active edit cell and always
select whole rows (as in a browser-type grid)?

5.87 How can I prevent all the cells in my DataGrid from being edited
without deriving GridColumnStyle?


Thanks!

Best regards,

Thanks Gary for your replay,
I setting my dataGrid with the dataSet by:
m_DataSet = new myDataSet();// myDataSet is created by a XSD schema.
DataTable defectsTable = m_DataSet.Tables["Defects"]
myDataGrid.DataSource = new DataView(defectsTable);

All my cells are not editable, but in same cases the TexBox cells get in
edit mode while the text can not be changed, but the cell become gray and a
default context menu is shown overriding my own.

For the Windows Forms FAQ:
5.7 - Not good for me because then the user can do nothing with the grid.
5.11 - Doing that.
5.18 - Done that, not solving my problem,.
5.41 - Like 5.18, not solving my problem.
5.87 - Why should I do that?! and in my case the rows are added on runtime
so this function will have to used at any row adding. I did it but the
Control.Count is always 2 and this 2 are the scrollbars.

I'll be very happy if you have any more suggestions.

Since the highlightening of the selected cell is a built-in feature of the
standard Winform datagrid control, I am afraid I don't have another idea
than the above one

Thanks for your understanding!

Hi Gary,

If the highlighting of the selected cell is a built-in feature of the
standard Winform datagrid control, maybe I can drived from this control and
do something about it by overriding some functionally.

Maybe you have any suggestion in that direction ?

Hi Sharon,

If you would like to implement your own custom datagrid control, I suggest
you consult it in a more appropriate managed newgroup, you'd get better and
quicker help there:

microsoft.public.dotnet.framework.windowsforms.controls


Thanks for your understanding!
