我通过数据绑定填充了一个datagrid:

this.dataGridInfo.SetDataBinding(m_DataSet,m_TableName);

可以正确显示数据，也可以用dataGridInfo[i,j].ToString()来读某单元格的内容，但this.dataGridInfo.TableStyles.count确等于0，也就是无法用this.dataGridInfo.TableStyles[0].GridColumnStyles[i].Width来设置宽度，该这类情况该如何设置列宽？窗口为winform.

DataGridTableStyle dgStyle = new DataGridTableStyle();
dgStyle.MappingName = dtExamset.TableName;
DataGridColumnStyle dcEnddate = new DataGridTextBoxColumn();
dcEnddate.MappingName = "enddate";
dcEnddate.HeaderText = "结束时间";
dcEnddate.Width = 75;
dgStyle.GridColumnStyles.Add(dcEnddate);

this.dgExamset.TableStyles.Add(dgStyle);
