Thanks. I haven't mastered things in jsfiddle yet, sorry.
I have managed to recreate the problem using your examples, perhaps you could check it out for me...or spot what I'm doing wrong.
I've changed two lines in your "Grid Parts" demo so that the obj variable is now as follows...
var obj = {
width:'100%',
height: 360,
showTop: false,
showBottom: false,
//collapsible: false,
showHeader: false,
roundCorners: false,
rowBorders: false,
columnBorders: false,
selectionModel: { type: 'cell' },
hoverMode: 'row',
// numberCell: { show: false },
numberCell: { show: true, resizable: true, title: "" },
stripeRows: false,
title: "Grid Constituents",
toolbar: {
items: [
{ type: "button", label: 'button on toolbar' }
]
}
};
The changes are to include hovermode as row, and enable the number cell. Then I clicked "Edit and Run" and it showed the same behaviour as I get (remember only with IE11 not with Chrome).
Then double click a cell to edit the cell text contents, but before typing move the mouse outside the text box and you may find the cursor and text vanish and a tiny text box and cursor appear in the very top left position of the grid.
Let me know if this recreates with you as well and I look forward to your advice on which element I've got wrong or missed when setting the grid up in this way.
Many thanks.
Tony
