Title: can't copy the text from the datagrid cell when extend cell edit.
Post by: frankgao on March 05, 2016, 02:43:58 AM
I saw the datagrid extension method from the web. I used this extension method, If datagrid has two cell,when I select all the MatCode cell text and loose the mouse left key, the select text turn unselect,so I I can't copy the cell text. May be this extension function disturbed, when I click the Quantity cell first, and copy the MatCode cell text,it's perfectly normal. I don't know how can I fix this problem. If you don't understand my description I will do better description. Thanks. { field: 'ma_code', title: 'MatCode', width: '110px', sortable: true },
{
field: 'qty', title: 'Quantity', width: '100px', editor: {
type: 'text', options: {
required: true
}
}
}
