Hi Hossein, 
 
Thanks for using Syncfusion products.  
 
We would like to le you know that you can set width of the columns based on the cell content by setting SfDataGrid.ColumnSizer as Auto. But we are little unclear about your requirement “extra space  set to all columns not to one column.”. We suspect that you need to increase the width of all the columns in addition to the default width set by the ColumnSizer. Kindly confirm this and revert to us with more details about your requirement with illustrations, if we have misunderstood your requirement.

Thanks for your responseThere is some sample of Extra space that is my mind. I want column space computed same as Auto , but extra space set to all column not to one column.

Hi Hossein, 

Thanks for the update.  

You can achieve your requirement to add extra space for the columns when the ColumnSizer is set as Auto by creating custom GridColumnSizer as shown below.  

Code example :  





this.dataGrid.GridColumnSizer = new GridColumnSizerExt(dataGrid); 
 
public class GridColumnSizerExt : GridColumnSizer 
{ 
 
    public GridColumnSizerExt(SfDataGrid dataGrid) 
        : base(dataGrid) 
    { 
 
    } 
 
    protected override double CalculateAutoFitWidth(GridColumn column, bool isAuto = false) 
    { 
        var width = 100 + base.CalculateAutoFitWidth(column, isAuto); 
 
        return width; 
    } 
}
