Hi,

I am using kendo ui treeview for sort of selectable hierarchical menu. This menu can contain pretty much data with deep tree hierarchy.

Ever since we implemented it (few years ago), we used approach suggested here:
https://docs.telerik.com/kendo-ui/knowledge-base/filter-out-search-results

This was working fine so far. However, we finally started updating things to the newer versions, and after update to 2022.2.802 this method became 3-4 times slower than before.
For example same filtering method with exactly same dataset and the same search keyword has following values:

Before update:
measure filter 0.4153999999985099

After update:
measure filter 2.279300000000745

Even this piece of code gets slower

      if (data) {
        // Re-apply the filter on the children.
        dataSource.filter({ field: "hidden", operator: "neq", value: true });
      }

(same iteration)

Old:
measure dsFilter 0.001200000002980232

New:
measure dsFilter 0.013800000000745058

Unfortunately, we cannot update directly to the latest version to test if it is better. This is because of styling braking changes which we have to address and other constraints that we have. We have to do it gradually.

Could you please advise what to do, since depending on the dataset size, filtering can last more than 7-8 seconds, and reseting filtering even longer. This basically renders the feature unusable. 

Thank you very much.

I've had a look and haven't found anything that answers my specific need.

I have an app that has a bill of materials and an order. 

Bill of materials is a self referencing hirarchy of parts e.g.

• Widget 1
  • Assembly 1
    • screw type 9
    • ring type A
    • spring type 6
  • Assembly 2
    • doodah X
      • Bit 9
    • Thinkgy 33
• Widget 2
  • etc

If Assembly 1 gets added to an order then it should no longer be visible as an option in the bill of materials (nor should anything under it). Or if doodah X gets added then it and its child should no longer be visible. This is obviously a very simplified example to demonstrate the need.

Is there a way to filter out the child nodes of a treelist like this?

Hi,

I’m trying to create an MDI type interface with the following behavior.

1. Two column layout with Drawer widget on left.
2. Open window within visible portion of right column.
3. Window cannot move outside of the visible portion of right column.
4. Window maximizes only to fill the visible portion of the right column.

Are there some examples around that would help or could y’all give some advice on how to do this?

Thanks,

Given a filter control and associated grid:

Is there a way to catch the click event of the apply button?

So, I can format the cells in the resulting grid? I tried this code in the dojo with an alert ("...") and I couldn't see the alert popup on the click. I am assuming I have something really wrong here.

I'm trying to hide/disable the tooltip when you hover over a page number in pagination toolbar in the kendo grid:

I've spend several hours reading the documentation and forums, awnsers are either outdated or do not seem to work.

How do I hide this tooltip/popup?

Hi team,

Where can be seen the SVG icons?

Are they the same as web font icons in this page? https://docs.telerik.com/kendo-ui/styles-and-layout/sass-themes/font-icons

Furthermore, what is the SVG equivalent for web font icon .k-i-loading ?

Best regards,

Laurent.

Hi,

Thank you for your answer to my merged rows question previously. Now I have the problem of getting the grid contents to sustain the format if I use Filter, Clear buttons in the Filter pop up or Sort. Example:

After setting the filter say for "Equals"  John Smith I get:

Buuuut. I really want:

Is there a way to "bypass" or extend the function where I could use the same implementation to restructure the rows like the above.

javascript - Does Kendo Grid support cell merge or not? - Stack Overflow

I think maybe I could create a listener to catch the Filter/Clear/Sort command and capture the JavaScript array structure and implement a solution similar to the one in Stack Overflow where I loop though the array and merge the cells of the records when the text content is equal? Maybe I am imagining this?

Hi team,

Consider this dojo: https://dojo.telerik.com/uZOruWEY

The tooltip is initialised without the width property. In that case, on first mouse-in the text is not wrapped and seems the right behaviour for me.

On next mouse-in, the text is wrapped! 

Best regards,

Laurent.
