## Description

How can I exclude certain columns from the exported PDF file in a Telerik UI for ASP.NET Core  Grid?

## Solution

#### Using the `k-pdf-export` Class and CSS

To hide a Grid column only during the PDF export, use a CSS rule and reduce the width of the target column to zero. This approach is implemented because the Kendo UI Drawing API adds [the `k-pdf-export` class](https://docs.telerik.com/kendo-ui/framework/drawing/pdf-output/custom-appearance#using-the) on all elements of the exported content and you can target specific elements in the following way.

```
<style>
  .k-pdf-export colgroup > col:nth-child(4) {
    width:0; /* hides only the 4th column during PDF export */
  }
</style>

```

For example refer to this [Telerik REPL Project](https://netcorerepl.telerik.com/mGEbbFlv24kGE8ul49)

#### Using the `showColum()` and `hideColumn()` Grid Methods

1. Hide the columns by using the [`hideColumn`](https://docs.telerik.com/kendo-ui/api/ui/grid/methods/hidecolumn) method within the [`pdfExport`](https://docs.telerik.com/kendo-ui/api/ui/grid/events/pdfexport) event handler.
2. When the export is done, display the hidden column by using the [`showColumn`](https://docs.telerik.com/kendo-ui/api/ui/grid/methods/showcolumn) method.

```
<script>
    var exportFlag = false;
    function onPdfExport(e){
             if (!exportFlag) {
              e.sender.hideColumn(1);
              e.preventDefault();
              exportFlag = true;

              e.sender.saveAsPDF().then(function(){
                e.sender.showColumn(1);
                exportFlag = false;
              });

            }
    }
</script>
```
