DataGrid 获取某行某列的值

Question

我想获取syncfusion的DataGrid中某个单元格的值

像这样：

<dataGrid:SfDataGrid x:Name="sfDataGrid">         
</dataGrid:SfDataGrid>

C#:

           Sfdatagrid\[i,j\] is useless.

如何获取此单元格的值。

https://help.syncfusion.com/winui/datagrid/overview 文档在这个官方文档中，我没有找到如何根据行和列的索引获取这个单元格的值。

我想根据行和列的索引得到这个单元格的值

Column A	Column B
Cell 1	Cell 2
Cell 3	Cell 4

比如我想根据行和列的索引得到这个单元格的值

我应该如何用c#编写代码

你需要根据SfDataGrid中的行列索引获取该单元格的值，可以通过SfDatGrid中的View.GetPropertyAccessProvider.GetValue方法实现。请参考下面的代码片段，

   private void OnGetCellValueClicked(object sender, RoutedEventArgs e)
   {
        // Get the cell value for RowIndex = 5 and ColumnIndex = 2            
        int rowIndex = 5;
        int columnIndex = dataGrid.ResolveToGridVisibleColumnIndex(2);

        object record = null;

        if (columnIndex < 0)
            return;

        var provider = this.dataGrid.View.GetPropertyAccessProvider();           

        var mappingName = dataGrid.Columns[columnIndex].MappingName;

        var recordIndex = this.dataGrid.ResolveToRecordIndex(rowIndex);

        if (this.dataGrid.View.TopLevelGroup != null)
        {
            var displayElement = this.dataGrid.View.TopLevelGroup.DisplayElements[recordIndex];

            if (displayElement == null)
                return;
            if (displayElement is RecordEntry)
                record = ((RecordEntry)displayElement).Data;
        }
        else
        {
            record = this.dataGrid.View.Records[recordIndex].Data;
            if (record == null)
                return;
        }            
        var cellValue = provider.GetValue(record, mappingName);

        //here display the cell value for RowIndex = 5 and ColumnIndex = 2
        if (cellValue != null)
            txtGetCellValue.Text = cellValue.ToString();
   }
