Automatically add character to editing cell, but dont fire Cell Update
posted

Hi there,

I have this scenario: Client can define many sub-packs in Grid A, each being identified with a letter (sub code)

In grid B, client can build packs based on sub-packs, and in any combination.

The pack code must be constructed using the sub pack codes concatenated with a plus sign (+) e.g.

A

A+B

A+B+C

B+C+D

I would like the + sign to be automatic i.e. the user must type AB to get A+B, and BCD to get B+C+D, however duplicates are not allowed. I would like the + sign to be added without firing the cell update events, where the duplicates are tested.

Can this be accomplished? I have had no luck - Text property is read-only and cannot be set, and setting Value property fires Update.

Thanks

Deon

    Hello Deon,

    Please take a look at the UltraGridCell.EditorResolved. By setting the EditorResolved.Textbox.Text you will not fire Update(). The following snippet demonstrates inserting "+" into the Editor's text:

    private void UltraGrid1_KeyUp(object sender, KeyEventArgs e)
            {
                if (ultraGrid1.ActiveCell.IsInEditMode)
                {
                    EditorWithText editor = (EditorWithText)ultraGrid1.ActiveCell.EditorResolved;
                    string text = editor.CurrentEditText;
                    if (text.Length > 1)
                    {
                        for (int i = 1; i < text.Length; i += 2)
                        {
                            if (text[i] != '+')
                            {
                                text = text.Insert(i, "+");
                            }
                        }
                        editor.TextBox.Text = text;
                        editor.SelectionStart = text.Length;
                    }
                }
            }

    Please let me know how I can be of further assistance.
