Keep the select all option when filtering

Hi,

Hopefully you can help us out with this!

On Kendo Grid, when filtering, we have an option 'Select All' as you can see below.

 

Now if we run a search for 'B' we get the below:

Now the select all option has disappeared and in some cases we would have a lot of options to enable.

 

Any ideas?

Thanks

Mark

Hi, Mark,

I have converted this to a Public Feedback item and added the votes from the people who were asking about this functionality.

Hello, Mark,

Thank you for the provided explanations.

Currently, there is no built-in way in which we can keep the  'Select All' checkbox, however I think this would be a great enhancement to the FilterMultiCheck. If you do not mind it, I would like to convert this thread to a public Feedback Portal item so others can upvote it. I found a forum thread where others have asked for this functionality, so I believe it has a reasonable chance to become popular.

Meanwhile, if you want to achieve it, you will need to override some Kendo internal functions that will help keep the select all checkbox visible and its state updated accordingly:

kendo.ui.FilterMultiCheck.fn.checkAll = function(){
            var state = this.checkBoxAll.is(":checked");
            this.container.find(":checkbox:visible").prop("checked", state);
          }

          kendo.ui.FilterMultiCheck.fn.updateCheckAllState =  function() {
            if (this.options.messages.selectedItemsFormat) {
              this.form.find(".k-filter-selected-items").text(kendo.format(this.options.messages.selectedItemsFormat, this.container.find(":checked:not(.k-check-all)").length));
            }
            if (this.checkBoxAll) {
              var state = this.container.find(":checkbox:not(.k-check-all):visible").length == this.container.find(":checked:not(.k-check-all):visible").length && this.container.find(":checkbox:not(.k-check-all):visible").length !==0;
              this.checkBoxAll.prop("checked", state);
            }
          }

And styles:

 <style>
      .k-multicheck-wrap .k-item:first-child {
        display:inline-block !important;
      }
        .k-multicheck-wrap {
          overflow-x: hidden;
        }
      </style>

Here is a runnable example for your reference:

Let me know what you think.
