How to get textbox widget inside grid to work property? - dojo

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.

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, '&').replace(/</g, '<') : v;
o = o.replace ? o.replace(/&/g, '&').replace(/</g, '<') : 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
}
]];
