Clearing a grid

[Jonathan Bleeker]

Hi

How does one clear a Grid control in WPF? Preferably in a way to reset it to what it was when it first initialized. The WinForms ClearCells method doesn't seem to exist in the GridControl in WPF.

Hi Jonathan, 

 

Thanks for using Syncfusion products.  

 

The GridControl works on how you define the styles, either through QueryCellInfo or manually setting those styles.  

 

1. Through QueryCellInfo, you would have an underlying store, which you could simply set it to NULL and reset the Model.RowCount and Model.ColumnCount.
2. Manually applying styles, then you can clear the internal lists maintained in the Model as,

this.gridControl.Model.VolatileCellStyles.Clear(); 

this.gridControl.Model.Data.Clear(); 

this.gridControl.InvalidateCells();

Invalidate by Range of cells: https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridControlBase.html#Syncfusion_Windows_Controls_Grid_GridControlBase_InvalidateCell_Syncfusion_Windows_Controls_Grid_GridRangeInfo_  

 

Please let us know if you need any further assistance on this.
