Installed products are Telerik UI for ASP.NET + Kendo UI for jQuery. Version R1 2018 (Version number: 2018.1.117)
I'm trying to use embedded Export to Excel function and... possible I'm wrong but it looks like this function does not support columns filtering in the right way.
I have not so simple grid, ny grid has dynamic columns, as we can see below 'columns' - is incoming parameter for grid creation.
You can see my examplebelow (with most important functions)
And when I have grid data and trying to apply just some simple filter, for example - by simple text field 'Surname', grid filters my records and this is absolutly Ok.
But when I press 'Export All' button - generated file is not correct. It generates either just only header or quite 'random' result, but not the correct one ... which is presented on UI.
Can you suggest something?
ps I've attached 2 images to do my question more clear.
1st: if I play with columns visibility and try to export -> all is ok
2nd: if I play with column filter and try to export -> unexpected result
