filter button disabled in grid filter menu popup

[Chahid]

Hello, I am currently facing an issue with the "Filter" button in the filter menu popup of my grid.

I implemented a grid with a customized filter menu where I have set the [extra] option to false so I have to fill only one input, as following:

<kendo-grid-column field="ProductName" title="Product Name">

   <ng-template kendoGridFilterMenuTemplate let-filter let-column="column" let-filterService="filterService">

     <kendo-grid-string-filter-menu [extra]="false" [column]="column" [filter]="filter" [filterService]="filterService">

     </kendo-grid-string-filter-menu>

   </ng-template>

</kendo-grid-column>

I used the same code to create other grids in my application and I am not facing this issue. Here when I open the filter menu popin, the "Filter" button is first disabled which is normal as I must type something in the filter input to enable it, but even if I do, the "Filter" button stays disabled, and I couldn't figure out what am I missing.

Is there any generic bad implementation that can cause this behavior and that I can fix? Or can I at least make the "Filter" button always clickable (I tried to remove the [disabled] option from the template in the kendo-grid-string-filter-menu file but I still have the same issue)?

Thank you in advance for you reply and tell me if you need some further informations.

Hi Chahid,

Thank you for the provided details.

The markup looks valid and produces a working filter:

https://stackblitz.com/edit/angular-wsmorg

Please ensure that the filter descriptors are passed to the Grid filter input and  the data is correctly filtred on filterChange (dataStateChange) event:

   <kendo-grid
      [data]="gridData"
      [filter]="filter"
      filterable="menu"
      (filterChange)="filterChange($event)"
      [height]="400"

  public filter: CompositeFilterDescriptor;
  public gridData: any[] = filterBy(sampleProducts, this.filter);

  public filterChange(filter: CompositeFilterDescriptor): void {
    this.filter = filter;
    this.gridData = filterBy(sampleProducts, filter);
  }

I had the same issue. I updated it all to the latest version of Telerik and it worked.

I am having the same issue, none of the solution works.
Here is the stackblitz:
https://stackblitz.com/edit/angular-2vd3ci?file=src%2Fapp%2Fapp.component.ts

import { Component } from '@angular/core';
import { sampleProducts } from './products';
import { Product } from './model';
import { paperclipIcon } from '@progress/kendo-svg-icons';
import { CompositeFilterDescriptor } from '@progress/kendo-data-query';

@Component({
  selector: 'my-app',
  template: `
        <kendo-grid [kendoGridBinding]="gridData" filterable="menu" 
        [height]="250" [style.width.px]="400">
        (filterChange)="dataGridFilterChange($event)"
        [filter]="filter"
            <kendo-grid-column field="ProductID" title="Product ID" [width]="150" [filterable]="true"> 
            <ng-template kendoGridFilterMenuTemplate let-column="column"
        let-filter="filter" let-filterService="filterService">
              <kendo-textbox textField="text" placeholder="" class="custom-fill-mode"            
              (valueChange)="onTextFilterChange($event,column)">
              </kendo-textbox>
        </ng-template>
        </kendo-grid-column>
            <kendo-grid-column field="UnitPrice" title="Unit Price" filter="numeric"
            [filterable]="false">
        </kendo-grid-column>
        </kendo-grid>
    `,
})
export class AppComponent {
  public icons = { paperclip: paperclipIcon };
  public gridData: Product[] = sampleProducts;
  //Filter
  public filter: CompositeFilterDescriptor;
  ngOnInit(): void {
    try {
      this.filter = {
        logic: 'and',
        filters: [],
      };
    } catch (er) {}
  }
  dataGridFilterChange(filters: CompositeFilterDescriptor) {
    this.filter = filters;
    console.log(filters);
  }
  public onTextFilterChange(value, col) {
    let idx = this.filter.filters.findIndex(
      (filt) => filt['field'] == col.field
    );
    if (idx > -1) {
      this.filter.filters.splice(idx, 1);
    }
    this.filter.filters.push({
      field: col.field,
      operator: 'eq',
      value: '123',
    });
    this.dataGridFilterChange(this.filter);
  }
}

Hi Yamunadevi,

Thank you for the provided code snippet.

In order to enable the Filter button, and filter the Grid correctly, provide the filterService to the onTextFilterChange event handler:

 <ng-template kendoGridFilterMenuTemplate let-column="column"
        let-filter="filter" let-filterService="filterService">
              <kendo-textbox textField="text" placeholder="" class="custom-fill-mode"            
              (valueChange)="onTextFilterChange($event,column, filterService)">
              </kendo-textbox>
        </ng-template>

Inside the event handler use the filter service, to filter the Grid data like:

  public onTextFilterChange(value, filterService: FilterService) {
    filterService.filter({
      filters: [
        {
          field: 'ProductID',
          operator: 'eq',
          value: value,
        },
      ],
      logic: 'or',
    });
  }
