DataGrid stopping user interaction.

[JasonShaw]

I am currently trying to create a form with a variable number of TextBoxes and a single DataGrid that is used to display historical data. I have programatically set up any number of TextBoxes and a DataGrid with the appropriate number of columns showing.

As the DataGrid is only for showing data I do not want the user to be able to select anywhere on the grid so I added an event handler for the Enter event

metDatagrid.Enter += new EventHandler(metDatagrid_Enter);
...
 
void metDatagrid_Enter(object sender, EventArgs e)
        {
            //metDatagrid.SelectNextControl(btnCancel, true, true, false, true);
            btnConfirm.Select();
        }
 

First I tried the "SelectNextControl" command (now commented out) which did not have any effect. Then I tried to force the issue by Selecting an existing button on the form, this seems to work once but any subsequent action allows the user into the DataGrid.

What am I doing wrong ?

Thank you
Jason

I think you might be able to change this behaviour by setting the DataGridView's EditMode to "EditProgrammatically".

When the DataGridView is set to this mode, editing begins only when the BeginEdit method is called.

If you never call the BeginEdit method then one could assume that your DataGridView will never be editable.

Not entirely sure this will work because I haven't tried it but in theory it makes sense to me :)

Hi Frinny

I am using a DataGrid not a DataGridView which does not have that method available to me.

Thanks anyway
Jason

Please take a look at the MSDN documentation for the DataGrid. That article tells you how to do what you want.

In the future please try to research the problem a little more before asking for help. A great place to start researching is the MSDN Library. I recommend bookmarking this link and using the MSDN library as your primary resource whenever you are developing .NET applications.

I must be missing something. Have read through page twice and not found any solution. Setting read-only to True avoids any updating occurring but the user is still able to select various cells. What I was looking to achieve was a table of historical data but not allow user to do anything but use the scroll bar if necessary.

Just to clarify...this is a desktop application, right?

Not quite sure what to answer to that.

It is a windows application using windows forms. The form I am trying to use is in a separate class which is launched as a dialogue box. I am developing in a Citrix environment though.

Hope this is the answer you wanted.

Thanks
