Possible column index bug with ShowRowHeader

[Sam Chan]

Hi,

If ShowRowHeader="False", I can lookup the index of a column using SfDataGrid.Columns.IndexOf() and then use that index in a call to SfDataGrid.MoveCurrentCell() to make a cell in that column current. However, if ShowRowHeader="True", the same call to MoveCurrentCell() would make the cell to the left of the intended cell current. This may be problematic because you have to check the current state of ShowRowHeader in order to offset the column index properly when setting a cell current.

Or should a different API be used to achieve selecting a current cell based on a column index independent of ShowRowHeader?

Sam

Hi Sam, 

 

Thank you for contacting Syncfusion support. 

 

We have checked your query.  You can achieve your requirement by two way as shown below. 

 

Way 1: You can resolve and get the appropriate column index by considering the ShowRowHeader  column as shown in the below code, 

 

Code Snippet: 

private void Button_Click(object sender, RoutedEventArgs e) 

{ 

    var colIndex = this.dataGrid.Columns.IndexOf(this.dataGrid.Columns["QS1"])+(this.dataGrid.ShowRowHeader?1:0); 

    this.dataGrid.MoveCurrentCell(new RowColumnIndex(1, colIndex), true); 

} 

 

Way 2: Also, you can use ResolveToScrollColumnIndex method to get the column index as shown below, 

 

Code Snippet: 

private void Button_Click1(object sender, RoutedEventArgs e) 

{ 

    var colIndex = this.dataGrid.Columns.IndexOf(this.dataGrid.Columns["QS1"]); 

    var index1 = this.dataGrid.ResolveToScrollColumnIndex(colIndex); 

    this.dataGrid.MoveCurrentCell(new RowColumnIndex(1, index1), true); 

}
