start editing and cursor to the end of a word Posts

Hi,

I have a problem with editing cells. Is there any way to set the cursor to the end of the word so that when you start editing has not been marked text in a cell,but the cursor was on the end of words just?

Thank you for your help.

Hello Jane,

This can be achieved through a custom editor. In the demo Custom Column Editor modify the first column as follows:

columns: [
    {
        text: 'First Name', columntype: 'template', datafield: 'firstname', width: 80, createeditor: function (row, cellvalue, editor, cellText, width, height) {
            // construct the editor.
            var inputElement = $("<input/>").prependTo(editor);
            inputElement.jqxInput({ source: getEditorDataAdapter('firstname'), displayMember: "firstname", width: width, height: height });
        },
        initeditor: function (row, cellvalue, editor, celltext, pressedkey) {
            // set the editor's current value. The callback is called each time the editor is displayed.
            var inputField = editor.find('input');
            inputField.val(cellvalue);
            inputField.jqxInput('selectLast');
        },
        geteditorvalue: function (row, cellvalue, editor) {
            // return the editor's value.
            return editor.find('input').val();
        }
    },

and your required functionality will be implemented.

Thanks, it works well. I still needed to advise how to do the editing with key F2, after which the word is again selected.

Hi Jane,

As I understand, you wish to enter edit mode and select all text in the cell on pressing F2. If this is the case, please take a look at the further expanded example:
