inserting CR when user types ALT-ENTER

[Eric Weber]

Similar to Excel, when a user is editing a cell in a GGC, how can I get the ALT-ENTER keystroke combination to insert a carriage return?

thanks!

Hi Eric,

You need to have a custom engine that supports saving row heights. The custom engine allows resizing of rows independent to know more on that refer the sample in :\Program Files\Syncfusion\Essential Studio\4.1.0.10\windows\Grid.Grouping.Windows\Samples\ResizableRows.

The custom engine should be added this way in the form''s ctor before InitializeComponent call.
GridEngineFactory.Factory = new GroupingEngineFactory();

Then using TableControlCurrentCellActivated and QueryCellStyleInfo setting these properties mentioned in the code snippet below you can use Enter key to create a new line within a cell.

private void gridGroupingControl1_TableControlCurrentCellActivated(object sender, GridTableControlEventArgs e)
{
e.TableControl.AllowTextBoxAutoSize = true;
e.TableControl.WantEnterKey = false;
}

private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
e.Style.AutoSize = true;
e.Style.AllowEnter = true;
}

Best regards,
Stanley

Thanks for the advice Stanley. My grid is already using syncfusion''s custom row height engine, and I have already experimented with WantEnterKey and AllowEnter. Here''s what I''ve noticed so far, and why I asked the question...

In my editable GGC (without doing any special coding) if I am editing a cell and then press the ENTER key, the cell editing ends. This is great...just like Excel...so far so good.

If I implement WantEnterKey and AllowEnter, then, as you said, I''ll be able to enter blank lines into the cell when I press the ENTER key. But then how does the user end their cell editing session (w/o touching the mouse)?

Just like with Excel, I want ALT-ENTER to add blank lines to a cell, not ENTER. ENTER should be used for ending cell editing.

Thanks!

Hi Eric,

It is not that necessary to use a mouse interaction to come out of the cell. Tab, Shift+Tab or the arrow keys also helps in navigating and there by ends the editing. I will also update this thread if a sample could be made working with Alt+Enter.

Why won''t something like this work?

But instead of inserting a "hello", I could enter a new line.

private void TableControl_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
if (e.Alt == true && e.KeyCode == Keys.Enter)
{
GridCurrentCell cc = this.TableControl.CurrentCell;
TextBoxBase tb = ((GridTextBoxCellRenderer)cc.Renderer).TextBox;
tb.Text.Insert(0, "hello");
}
}

And unfortunately this code doesn''t work, why not? What am i missing? Replacing the last line with tb.SelectAll() works just fine.

Thanks!

Hi Eric, This works for me. this.gridGroupingControl1.TableControlCurrentCellKeyDown += new GridTableControlKeyEventHandler(gridGroupingControl1_TableControlCurrentCellKeyDown); private void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlKeyEventArgs e) { if((Control.ModifierKeys & Keys.Alt) != 0 && e.Inner.KeyCode == Keys.Enter) { Console.WriteLine("alt+enter"); e.Inner.Handled = true; GridCurrentCell cc = this.gridGroupingControl1.TableControl.GetNestedCurrentCell(); TextBoxBase tb = cc.Renderer.Control as TextBoxBase; if(tb != null) { tb.SelectedText = Environment.NewLine; cc.BeginEdit(); this.gridGroupingControl1.TableModel.RowHeights[cc.RowIndex] += 17; } } } Here is a sample.
