Hi FGGamboa,  

   

Thank you for using Syncfusion controls.   

   

SfDataGrid supports the scrolling events. You can use the ValueChanged and Scroll event for both Horizontal and Vertical scrolling in SfDataGrid. Please refer the below code snippet.  

C#:   

  this.sfDataGrid1.TableControl.VerticalScroll.ValueChanged += VerticalScroll_ValueChanged;   

  this.sfDataGrid1.TableControl.VerticalScroll.Scroll += VerticalScroll_Scroll;   

  

this.sfDataGrid1.TableControl.HorizontalScroll.ValueChanged += HorizontalScroll_ValueChanged;   

this.sfDataGrid1.TableControl.HorizontalScroll.Scroll += HorizontalScroll_Scroll;   

   

   

   private void VerticalScroll_Scroll(object sender, ScrollEventArgs e)   

   {   

       MessageBox.Show("Scroll event");   

   

   }   

   

   private void VerticalScroll_ValueChanged(object sender, EventArgs e)   

   {   

       MessageBox.Show("Scroll value changed event");   

   }   

   

   

         private void HorizontalScroll_Scroll(object sender, ScrollEventArgs e)   

  {   

      MessageBox.Show("Horizontal Scroll event");   

  }   

   

  private void HorizontalScroll_ValueChanged(object sender, EventArgs e)   

  {   

      MessageBox.Show("Horizontal Scroll value changed event");   

  }

For further and immediate clarity, is there any difference between ValueChanged versus Scroll events ?

[Vijayarasan Sivanandham]

Hi Yvo G,

Yes. Scroll events are only triggered while scrolling on UI Interaction in SfDataGrid. but ValueChanged event trigger for both UI Interaction and changing the scroll value programmatically in SfDataGrid.

Please let us know if you have any concerns in this.

M. Sivanandham, thanks a lot.

So far we've looked at :::

• sfDataGrid.TableControl.VerticalScroll.Scroll
• sfDataGrid.TableControl.VerticalScroll.ValueChanged
• sfDataGrid.TableControl.HorizontalScroll.Scroll
• sfDataGrid.TableControl.HorizontalScroll.ValueChanged

For even more clarity perhaps, I noticed there's also :::

• sfDataGrid.TableControl.WindowScrolled

Can anything be explained about this latter event, compared to the other four handlers ?

Hi Yvo G,

sfDataGrid.TableControl.WindowScrolled event occurs after the window has been scrolled. This event trigger for both UI Interaction and changing the scroll value programmatically in both Horizontal and Vertical scrolling in SfDataGrid.
