Scrolling in DoubleTextBox

[Denig]

Hi

i had a DoubleTextBox in the SfDataGrid with scrolling for the values.
But when i scroll, the value add 1 and also the whole DataGrid is scrolling, so that this Row is over my cursor.
Can i stop scrolling the Datagrid when the Mouse is on the Field ?

greets

Hi Greets, 

 

Thank you for contacting Syncfusion support. 

 

Can you make sure, you are setting AllowScrollingOnCircle property as True as show the like below code, so DataGrid won’t get scrolling when mouse wheel over the Numeric Column editor. 

 

Code Snippet: 

<Syncfusion:SfDataGrid x:Name="dataGrid" Grid.Column="0" 

                        AllowEditing="True" ItemsSource="{Binding Path=EmployeeDetails}" AllowFiltering="True" AllowSorting="False"  

                        ShowRowHeader="True"> 

    <Syncfusion:SfDataGrid.Columns> 

        <Syncfusion:GridNumericColumn MappingName="EmployeeId" AllowScrollingOnCircle="True"/> 

        <Syncfusion:GridTextColumn MappingName="EmployeeName"/> 

        <Syncfusion:GridTextColumn MappingName="City"/> 

        <Syncfusion:GridTextColumn MappingName="MailId"/> 

    </Syncfusion:SfDataGrid.Columns> 

</Syncfusion:SfDataGrid>

Hi Greets, 

 

Thanks for the update. 

 

We have analyzed your query. You can achieve your requirement by overriding ProcessPointerWheel  method in GridSelectionController class as shown like below code, 

 

Code Snippet: 

 

this.dataGrid.SelectionController = new GridSelectionControllerExt(this.dataGrid); 

 

internal class GridSelectionControllerExt : GridSelectionController 

{ 

    public GridSelectionControllerExt(SfDataGrid datagrid) : base(datagrid) 

    { 

 

    } 

    protected override void ProcessPointerWheel(MouseWheelEventArgs args, RowColumnIndex rowColumnIndex) 

    {            

        var currentCell = CurrentCellManager.CurrentCell;            

        var prop = DataGrid.GetVisualContainer().GetType().GetField("SuspendManipulationScroll", BindingFlags.NonPublic | BindingFlags.Instance); 

       if (currentCell.GridColumn.MappingName== "EmployeeId" && (currentCell.GridColumn is GridTemplateColumn) 

            &&  CurrentCellManager.CurrentRowColumnIndex.RowIndex == rowColumnIndex.RowIndex) 

        { 

            prop.SetValue(DataGrid.GetVisualContainer(), true); 

        }  

        else 

        { 

            prop.SetValue(DataGrid.GetVisualContainer(), currentCell.IsEditing); 

        } 

    } 

}
