How to customize the isEnable property in PART_OkButton of filtertogglebutton - From 178541

Question

When I click the filtertogglebutton, I am seeing a popup for changing filters. I want to affect " PART_OkButton"'s isEnable property. If filter popup has elements inside, it can be isEnable = true but if it has not any element inside, it must be isEnable = false. I tried to do binding but I saw an error about "cannot find the binding value".

Hi Kivanc Yilmaz,

Your requirement to customize the isEnable property in PART_OkButton of the filter
toggle button in SfDataGrid by customizing the FilterItemsPopulating event.
Refer to the below code snippet,

//Event subscription
  this.AssociatedObject.FilterItemsPopulating
  += OnFilterItemsPopulating;
   
  //Event customization
  private void OnFilterItemsPopulating(object sender, GridFilterItemsPopulatingEventArgs e)
  {
      if (e.FilterControl != null)
      {
          //Here gets the PART_OkButton by using reflection in SfDataGrid
          var okButton =
  (Button)e.FilterControl.GetType().GetField("OkButton", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(e.FilterControl);
   
          //Here get the SfDataGrid
          var sfDataGrid = sender as SfDataGrid;
   
          if(sfDataGrid != null && okButton != null && sfDataGrid.View != null && sfDataGrid.View.Records != null)
          {
              //here checks the condition based on your scenario
              if(sfDataGrid.View.Records.Count == 0)
              {
                  //Here disable the PART_OkButton of filtertogglebutton
                  okButton.IsEnabled = false;
              }
              else
                  //Here enables the PART_OkButton of filtertogglebutton
                 
  okButton.IsEnabled = true;
          }
      }
  }
