How to get textbox widget inside grid to work property?

Question

I have placed a textbox widget inside grid cell by using formatter. However, I cannot move my cursor around nor select text inside the textbox.

E.g. http://jsfiddle.net/g33m9/69/

Does anyone know how to fix this?

Thanks

You need to set the column as 'editable' so that the Grid component will know how to handle keypressed events. So a modification to the layout is in order

from

var layout = [[
        {name: 'Column 1', field: 'col1'},
        {name: 'Column 2', field: 'col2', width:'200px', formatter: func}
    ]]; 

to

var layout = [[
        {name: 'Column 1', field: 'col1'},
        {name: 'Column 2', field: 'col2', width:'200px', formatter: func, editable: true}
    ]]; 

Edit state activates by doubleclick.

Now, OP wants it to be a fully bloated widget, popping up in the editable state. For this to be scaleable up with any number of rows/columns i will restrict this to the edit state, so that the value simply shows text but once double-clicked it will pop a FilteringSelect. Same principle goes with the dijit widget ValidationTextBox.

Currently (1.7.2) the possible celltypes are: dojox.grid.cells.Bool dojox.grid.cells.ComboBox dojox.grid.cells.DateTextBox dojox.grid.cells.Select

Catch me SEO:

example of custom dojox.grid cellType widget - semi-programmatic

First step - create some data

var i = 0,
data = {
    identifier: 'id',
    items: [
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++}
    ]
},
// The item label which holds visible value and which holds the value to represent
searchAttr = 'value',
valueAttr = data.identifier,
// The store to use for select widget
store = new dojo.data.ItemFileReadStore({ data: data }),
// And the options, reassembling the valid options we will present in dropdown
// Used when cellType is dojox.grid.cells.Select to name the allowable options
options = [];
dojo.forEach(data.items, function(it) { options.push(it[searchAttr])});

Tricky part - Define a cellType

Lets extend the existing dojox.grid.cells.Cell, it has two key features - an edit-state-formatter and the default-formatter. The default would work just fine. Last but not least, we'll override the '_finish' function allthough allow the Cell to process its own definition too.

var whenIdle = function( /*inContext, inMethod, args ...*/ ) {
    setTimeout(dojo.hitch.apply(dojo, arguments), 0);
};

var FilteringSelectCell = declare("dojox.grid.cells.FilteringSelect", [dojox.grid.cells.Cell], {
    options: null,
    values: null,

    _destroyOnRemove: true,
    constructor: function(inCell){
        this.values = this.values || this.options;
    },

    selectMarkupFactory: function(cellData, rowIndex) {
        var h = ['<select data-dojo-type="dijit.form.FilteringSelect" id="deleteme' + rowIndex + '" name="foo">'];
        for (var i = 0, o, v;
        ((o = this.options[i]) !== undefined) && ((v = this.values[i]) !== undefined); i++) {
            v = v.replace ? v.replace(/&/g, '&amp;').replace(/</g, '&lt;') : v;
            o = o.replace ? o.replace(/&/g, '&amp;').replace(/</g, '&lt;') : o;
            h.push("<option", (cellData == v ? ' selected' : ''), ' value="' + v + '"', ">", o, "</option>");
        }
        h.push('</select>');
        return h;
    },
    textMarkupFactory: function(cellData, rowIndex) {
        return ['<input class="dojoxGridInput" id="deleteme' + rowIndex + '" data-dojo-type="dijit.form.ValidationTextBox" type="text" value="' + cellData + '">']

    },
    // @override
    formatEditing: function(cellData, rowIndex) {

        this.needFormatNode(cellData, rowIndex);
        var h = (cellData == "W1")
            ? this.textMarkupFactory(cellData, rowIndex)
            : this.selectMarkupFactory(cellData, rowIndex);
        // a slight hack here, i had no time to figure out when the html would actually be inserted to the '<td>' so.. Use 'debugger' statement and track function to hook into
        whenIdle(function() {
            dojo.parser.parse(dojo.byId('deleteme' + rowIndex).parentNode);
            var w = dijit.byId('deleteme' + rowIndex);
            w.focus()

        });
        return h.join('');
    },
    // clean up avoiding multiple widget definitions 'hanging'
    _finish: function(inRowIndex) {
        this.inherited(arguments)
        dijit.byId('deleteme' + inRowIndex).destroy();
    },
    // needed to read the value properly, will work with either variant
    getValue: function(rowIndex) {
        var n = this.getEditNode(rowIndex);
        n = dijit.getEnclosingWidget(n);
        return n.get("value");
    }
});

Last bit, a new layout

var layout = [[
      { name: 'Column 1', field: 'col1' },
      { name: 'Column 2', field: 'col2', 
        cellType: FilteringSelectCell, options: options, editable: true
      }
]];
