DataGrid列表绑定序号自增

Posted 2020-08-21 小柒~

思路：

在每个datagrid的第一列加上一个模板列，里面只定义一个textblock

之后在datagrid的行加载事件中，给每个行的textblock加上一个编号。

xaml代码：

                        <sdk:DataGridTemplateColumn  CanUserSort="False" Header="序号">
                            <sdk:DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                </DataTemplate>
                            </sdk:DataGridTemplateColumn.CellTemplate>
                        </sdk:DataGridTemplateColumn>

cs代码：

        // 加载控件值
        /// <summary>
        /// 加载控件值
        /// </summary>
        private void InitControl()
        {
            try
            {
                #region 控件赋值

                this.OtherTechnique_Infos_Schema = null;

                this.tbTEXT.Text = string.Empty;


                this.dgList.ItemsSource = null;

                this.dgList.ItemsSource = this.listOtherTechnique_Infos_Schemas.OrderBy(t => t.CODE);
                this.dgList.LoadingRow += dataGrid_LoadingRow;

                #endregion 控件赋值
            }
            catch (Exception)
            {
                throw;
            }
        }

        /// <summary>
        /// 序号
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        public void dataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            var index = e.Row.GetIndex();
            var cell = this.dgList.Columns[0].GetCellContent(e.Row) as TextBlock;
            if (cell != null) cell.Text = (index + 1).ToString();
        }

大功告成！
