Suppose I have a data source supplying fields x, y, z and I use
$('#grid').kendoGrid ({
...
  columns: [
    { field:'x', title:'X Coordinate', width:'40px' }
  , { field:'y', title:'Y Coordinate', width:'40px' }
  , { field:'z', title:'Z Coordinate', width:'40px' }
  ]
...
})
and get everything looks ok.

Now suppose there is a button that when clicked should set all the column widths to 80px.

$('#button').click(function() {
??? what goes here ???
})

This is what I have come up with, not sure how robust it is.  Feedback is appreciated.

Presume
grid is id "grid"
getSettings returns a JSON such as
{ field-name-1: width-1
, field-name-2: width-2
...
, field-name-n: width-n
 }

$.ajax({url: getSettingsUrl, data:{property:"column-widths"}})
.done (function(data){
    var
        field, th, index,
        headerTable = $('#grid'.k-grid .k-grid-header table'),
        contentTable = $('#grid'.k-grid .k-grid-content table'),
    ;
 
    for (field in data) {
        th = $(headerTable).find('th[data-field="'+field+'"]');
        if (th.length) {
            index = $.inArray(th[0], th.parent().children(":visible"));
            col = headerTable.find('colgroup col:eq('+index+')')
                .add (contentTable.find('colgroup col:eq('+index+')'))
            ;
            col.css('width', data[field]);
        }
    }
});

Hi Richard,

This functionality is not supported out of the box.

Currently the Grid provides opportunity to resize the columns only by drag-n-drop (demo). Generally speaking in order to change the width of the column with JavaScript you should modify the width of the corresponding <col> element of the content and header table. Here is a small example.

Alexander/Telerik,

Is your statement from Feb 2013: 

"This functionality is not supported out of the box. "

still correct?

If so is the example you provided still the recommended way to resize columns from JavaScript?

Thanks,

Greg.

I look forward to hearing if there is a better way, but just this week I solved this using code similar to the above.  First, I added a new value to every column definition called minWidth, for example:

{
    field: "Comment",
    title: "Comments",
    required: false,
    width: 150,
    minWidth: 80,
    attributes: { class: "editable-cell" },
}

 

And then I set resizeable true, and defined the columnResize listener like this:

columnResize: function(e)
{
    var columns = $("#grid").data("kendoGrid").columns;
 
    var headerTable  = $('.k-grid .k-grid-header table');
    var contentTable = $('.k-grid .k-grid-content table');
 
    var columnDefs = $(".k-grid-content colgroup:first col");
 
    for (var i = 0; i < columns.length; i++)
    {
        var minWidth     = columns[i].minWidth;
        var currentWidth = parseInt(columnDefs[i].style["width"], 10);
 
        if (minWidth > currentWidth)
        {
            // Reset the headers and columns to the same minimum width
            var col = headerTable.find('colgroup col:eq('+i+')')
                          .add(contentTable.find('colgroup col:eq('+i+')'));
 
            col.css('width', minWidth + "px");
        }
    }
}

Hello Greg,

Yes my statement from Feb-2013 is still correct. There is no build-in API method that will allow you to resize the columns via JavaScript.

Will this ever be implemented? I have a grid, which I autosize all columns on the databound listener. After this, some of my columns are not too small, as grid.autoFitColumn does not take into account a row filter box. Thanks!

Hi Marc,

The implementation of this feature is not in our immediate plans. I suggest to submit a feature request at Kendo UI Feedback portal. In this way the idea will be reviewed by other users, if it turns out to be popular we will consider it for one of our future releases.
