Enter key for moving to next cell on a new row when the cell is set to ReadOnly

[Avi]

Hi,

I use RadControls for WinForms Q2 2011.

I've set a column on my grid to ReadOnly for both EnterKeyMode and NewRowEnterKeyMode.

When navigating through cells with either Tab or Enter keys - it works fine and it jumps to the next editable cell. But, When navigating with Enter key on a new row through the read-only column - it stays on that cell and doesn't move on. I need to use Esc, arrows or mouse to release it.

Is it the right behavior? If so, is there some workaround for that?

Best Regards,

Boaz

Hi Avi,

Thank you for writing and sorry for the late response.

When you press the Enter key in EnterMovesToNextCell we always move to the next cell and we consider this behavior as normal. In case that the cell is read-only you cannot edit it and should press enter again.
You can easy workaround this behavior. You  should CurrentColumnChanged event and skip the column if the column is ReadOnly:

this.radGridView1.CurrentColumnChanged += new Telerik.WinControls.UI.CurrentColumnChangedEventHandler(radGridView1_CurrentColumnChanged);
        }

        void radGridView1_CurrentColumnChanged(object sender, Telerik.WinControls.UI.CurrentColumnChangedEventArgs e)
        {
            if (e.NewColumn.ReadOnly)
            {
                int nextIndex = e.NewColumn.Index + 1;
                if (nextIndex >= this.radGridView1.Columns.Count)
                {
                    nextIndex = 0;
                }

                this.radGridView1.CurrentColumn = this.radGridView1.Columns[nextIndex];
            }
        }

Please, refer to the attached project.
I hope this helps.

Hi
1 ) I want to change position tab between cells by enter key but I can't
2)  if tab was last cell, by enter key create new row and tab go to first cell in new row

tnx alot....

Hello Taha,

Thank you for writing.

1) In order to change the current cell with Enter key instead of the Tab key, you should set RadGridView's EnterKeyMode property to EnterMovesToNextCell:

radGridView1.EnterKeyMode = RadGridViewEnterKeyMode.EnterMovesToNextCell;

2) You should set RadGridView's NewRowEnterKeyMode property to EnterMovesToNextCell

radGridView1.NewRowEnterKeyMode = RadGridViewNewRowEnterKeyMode.EnterMovesToNextCell;

I hope this helps. Do not hesitate to contact us if you have other questions.

Hi
i 'm taha
About Question 2 , So i could't create new row by enter key when tab

please help me.
tnx

Hi,

You should set RadGridView's AllowAddNewRow property to true.
When set to true an empty row is added in which the user can enter data for the new record.

radGridView1.AllowAddNewRow = true;

I hope this helps. Kind regards,

When I edit a cell on the RadGridView and then tab to any other cell (not hit Enter), my application "bombs" (just shuts down).  My code only implements the CellFormatting and CellValueChanged events of the RadGridView.  If I remove (comment out) both events, I can edit a cell and tab to any other cell without the application shutting down.

Hello Curtis,

Thank you for writing.

I have to debug your custom logic in the CellFormatting and CellValueChanged events in order to find what causes this behavior. It is possible to send us a small build-able project where the issue can be reproduced? You can do that in a new support ticket.

A bit of topic, I would kindly ask you to open a new thread for each question that is not related to the main topic of the existing threads. This will avoid mixing several different topics in one thread, hence our community will be able to find information for the topics more easily in case it is interested.

Thank you for the understanding.

Hello, Peter

I figured out what was causing the problem.  In the CellValueChanged event, I called a method I wrote that sets the gridview's DataSource property to Nothing before reassigning it to a DataSet (in effect, clearing the gridview first).  When I deleted the code line that assigned Nothing to its DataSource property, the problem was eliminated.

Thanks for your prompt reply, Peter.

Hi Peter,

I'm facing a similar kind of issue when I try to enter a value in the cell and either use Tab or Enter. It works fine for both, but when I come back to the same cell and wants to change first entered value. I can change that value, but can't get out from that cell either by using Enter or Tab command or by clinking with mouse to another cell.
I have to use Escape key or F2 command to get out from that cell, but I lose my change, I don't want to use this Escape or F2 option.

Is there any solution via using Tab or Enter as it works first time?

Many Thanks
Ali
