Changing a column's mask from a keypress in the editor

[Bill]

I have a grid containing a GridViewMaskBoxColumn.  I want the mask on the cell to change when I hit the F4 key with the cell editor active.  Unfortunately when I change the column's Mask in the RadMaskedEditBoxEditorElement's KeyUp event handler while the editor is open it doesn't have an immediate effect; I have to switch to a different cell before the new mask takes effect.  How do I get the mask change to take immediate effect in the editor?

Hello Bill,

Thank you for contacting Telerik support.

I was able to change the mask when user press the F4 key while the editor is active. Please refer to the code below:

//Add the column

GridViewMaskBoxColumn mbc = new GridViewMaskBoxColumn("Value");

mbc.FieldName = "Value";

mbc.Name = "Value";

mbc.HeaderText = "Value";

mbc.MaskType = MaskType.Standard;

mbc.Mask = "###";

radGridView1.Columns.Add(mbc);

 

//wire to the event

private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

{

            if (radGridView1.CurrentColumn.Name.ToString() == "Value")

            {

                RadMaskedEditBoxEditor cmb = radGridView1.ActiveEditor as RadMaskedEditBoxEditor;

                if (cmb != null)

                {
((RadMaskedEditBoxEditorElement)(cmb).EditorElement).KeyUp -= new KeyEventHandler(Editor_KeyUp);



                    ((RadMaskedEditBoxEditorElement)(cmb).EditorElement).KeyUp += new KeyEventHandler(Editor_KeyUp);

                }

            }

        }

 

//Change the mask

void Editor_KeyUp(object sender, KeyEventArgs e)

{

            if (e.KeyCode == Keys.F4)

            {

                RadMaskedEditBoxEditorElement editor = (RadMaskedEditBoxEditorElement)sender;

                if (editor.Mask == "###")

                {

                    editor.Mask = "########";

                }

                else

                {

                    editor.Mask = "###";

                }

            }

 }

I hope this will help. Please let me know if you need any further assistance. All the best,
