How do I de-select a row after it's selected?

[Mark]

I'm currently using a SFDataGrid in WPF and I was wondering how do I de-select a row after it's selected?

Is there a row selected event so I can do like a 'if old selected row == new row selected then row selected = null?

Hi Mark, 

 

Thank you for using Syncfusion controls. 

 

We have analyzed your query, SfDataGrid supports different types of SelectionMode (Single, Multiple, Extended and None). By default, you can able to de-select the selected row in Multiple selection mode. So, could you please share which SelectionMode is you have used in your application, that will help us to provide the better solution.

Hi Mark, 

 

Thank you for your update. 

 

We have analyzed your query, currently we don’t have a support for de select the selected row in Single SelectionMode in SfDataGrid, but you can achieve your requirement by set the SelectedItem as null in PreviewMouseUp event in SfDataGird. 

 

Please refer the below code example 

 

dataGrid.PreviewMouseUp += dataGrid_PreviewMouseUp; 

void dataGrid_PreviewMouseUp(object sender, MouseButtonEventArgs e) 

{ 

    var record = this.dataGrid.GetRecordAtRowIndex(dataGrid.SelectionController.CurrentCellManager.CurrentRowColumnIndex.RowIndex); 

    if (dataGrid.SelectedItems.Contains(record)) 

        dataGrid.SelectedItem = null; 

}

We have considered to provide support for “Support to deselect a record in single selection mode” in WPF and logged feature request for the same. We will implement this feature in any of our upcoming release.  

 

At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know when this feature is implemented. We appreciate your patience until then. 

 

Thank you for requesting this feature and helping us define it. We are always trying to make our products better and feature requests like yours are a key part of our product growth efforts.

Thanks but unfortunately it's not working the way I need it to, it sets the selected item to null NO MATTER WHERE I do the mouse up event instead of just working if I mouse up on top of the selected row.

Hi Mark, 

 

Sorry for the inconvenience caused. 

 

You can get the row index from PointToCellRowColumnIndex method and set the SelectedItem as null, instead of get the row index from CurrentCell. 

 

Please refer the below code example 

 

dataGrid.PreviewMouseUp += dataGrid_PreviewMouseUp; 

void dataGrid_PreviewMouseUp(object sender, MouseButtonEventArgs e) 

{ 

    var rowIndex = dataGrid.GetVisualContainer().PointToCellRowColumnIndex(e.GetPosition(dataGrid.GetVisualContainer())).RowIndex; 

    var record = this.dataGrid.GetRecordAtRowIndex(rowIndex); 

    if (dataGrid.SelectedItems.Contains(record)) 

        dataGrid.SelectedItem = null; 

}
