Disappear row on IE 11

[Mariusz]

Hello,

I have a problem with show data in locked column on Internet Explorer 11. The problem appear for example when I expand some row or I added new to structure. When I use Chrome or Mozzila treelist behave good. I'm using the latest version 2015 Q1 (2015.1.429).

001.//this function get datasource and answer for expand rows
002.$getDataSource: function (opt) {
003.            var ds = opt.dataSource.transport,
004.                that = this;
005.
006.            return new kendo.data.TreeListDataSource({
007.                transport: {
008.                    read: function (options) {
009.                        var id = options.data.id,
010.                            data = that.$get.call(that, id);
011.                        if (isNullOrEmpty(data)) {
012.                            var params;
013.                            if (ds.expand.data && isFunction(ds.expand.data)) {
014.                                params = ds.expand.data.call(that);

Has anyone idea how fix this problem?

I've noticed another problem, in version 2014 Q3 combobox doesn't scroll top after read new data, in version 2015 Q1 always after read scroll is on top. I need the same solution  in version 2015 Q1 as this (topic from forum ).

Thanks.

Hello Mariusz,

 

We are not aware of such issue neither we can reproduce it on the online demos. We will need a runnable example or dojo which demonstrates the behavior in order to assist you further.

 

Regarding the ComboBox behavior in question please open a separate ticket as it is not related to the main theme in this thread.

You can see solution as this link.

Instruction to redo error:
- Expand row with ID 1
- Expand row with ID 2
- Expand row with ID 4
- Select row with ID 4
- Click „Add” buton
- Click „Refresh” buton
- The last row (Position 1.1.3) will no longer show its ID.

 Thanks.

Hello Mariusz,

 

The widget must have height set when using frozen columns. It is required when frozen columns are enabled.

Hello Nikolay,

Thanks for answer, but I've set height and the problem still appear. I've noticed that the problem disappear when I remove template from column.

Hello Mariusz,

I could not reproduce the problem in this reduced example. Please note that custom widgets are not supported, so please reproduce the problem with the official widget.
