总结 一、序言
这里使用的工具是VS2019.net版本使用的是4.5版本。素材插件使用的是materialDesign。分享是随缘更新
二、前期准备
1、现在Nuget里安装MaterialDesignColorsMaterialDesignThemes两个插件包。
2、在App.xaml文件里更改成下面代码部分
Application.ResourcesResourceDictionaryResourceDictionary.MergedDictionariesResourceDictionary Sourcepack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml /!--ResourceDictionary Sourcepack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml /--ResourceDictionary Sourcepack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml /ResourceDictionary Sourcepack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml /ResourceDictionary Sourcepack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml /!--ResourceDictionary Sourcepack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml /--ResourceDictionary Sourcepack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Blue.xaml//ResourceDictionary.MergedDictionaries/ResourceDictionary/Application.Resources
3、在所需要使用的界面里引用materialDesign在这个位置添加如下代码 xmlns:materialDesignhttp://materialdesigninxaml.net/winfx/xaml/themes 三、前端界面 前期工作做好了开始写前端。这里写的是用户组件
前端代码如下
UserControl x:ClassComponentLibrary.WPF.UserControls.PagingTUserControlxmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentationxmlns:xhttp://schemas.microsoft.com/winfx/2006/xamlxmlns:mchttp://schemas.openxmlformats.org/markup-compatibility/2006 xmlns:dhttp://schemas.microsoft.com/expression/blend/2008 xmlns:localclr-namespace:ComponentLibrary.WPF.UserControlsmc:Ignorabled GridBorder CornerRadius3 BackgroundTransparent BorderBrush{x:Null}Grid HorizontalAlignmentStretch Margin5 0 5 0 VerticalAlignmentTop WidthAuto Height30Grid.ColumnDefinitionsColumnDefinition Width150/ColumnDefinition Width150/ColumnDefinition Widthauto MinWidth500//Grid.ColumnDefinitionsGridGrid.ColumnDefinitionsColumnDefinition/ColumnDefinition//Grid.ColumnDefinitionsLabel Content每页显示: HorizontalAlignmentRight/ComboBox x:NamecomInt PreviewMouseDowncomInt_PreviewMouseDown Grid.Column1//GridTextBlock NametbkRecords Grid.Column1 ForegroundWhite Style{StaticResource PageTextBlock1} /StackPanel OrientationHorizontal HorizontalAlignmentRight Grid.Column2GridGrid.RowDefinitions RowDefinition Height50/RowDefinition/Grid.RowDefinitionsGrid.ColumnDefinitionsColumnDefinition Width50/ColumnDefinition Width50/ColumnDefinition Width*/ColumnDefinition Width50/ColumnDefinition Width50/ColumnDefinition Width50/ColumnDefinition Width30//Grid.ColumnDefinitionsTextBlock Grid.Column0 NamebtnFirst Text首页 IsEnabledFalse Style{StaticResource FancyTextBlockStyle2} /TextBlock Grid.Column1 NamebtnPrev Text上一个 IsEnabledFalse Style{StaticResource FancyTextBlockStyle2} /Grid Grid.Column2 Namegrid Grid.RowDefinitionsRowDefinition Height30 /RowDefinition/Grid.RowDefinitions/GridTextBlock Grid.Column3 x:NamebtnNext Text下一个 IsEnabledFalse Style{StaticResource FancyTextBlockStyle2} /TextBlock Grid.Column4 x:NamebtnLast Text未页 IsEnabledFalse Style{StaticResource FancyTextBlockStyle2}/TextBox Grid.Column5 x:NamepageGo VisibilityCollapsed MaxLength6 IsReadOnlyTrue Style{StaticResource PageTextBox} /Button Grid.Column6 x:NamebtnGo VisibilityCollapsed ContentGO IsEnabledFalse Style{StaticResource PageButton} //Grid/StackPanel/Grid/Border/Grid
/UserControl这是它的一个原型。
四、后台代码部分 这里后台写了两种数据模式一个是泛型数据类型一个是DataTable数据类型。两种下面代码会逐一分享给大家。
1、先定义些变量后面使用
private DataTable _dt new DataTable();
/// summary/// 每页显示多少条/// /summaryprivate int pageNum 10;/// summary/// 当前是第几页/// /summaryprivate int pIndex 1;/// summary/// 对象/// /summaryprivate DataGrid grdList;/// summary/// 最大页数/// /summaryprivate int MaxIndex 1;/// summary/// 一共多少条/// /summaryprivate int allNum 0;/// summary/// 声明一个泛型对象接受数据./// /summaryprivate Listobject obj;
2、先是按钮事件代码。 首页按钮
#region 首页/// summary/// 首页/// /summary/// param namesender/param/// param namee/paramprivate void btnFirst_Click(object sender, System.EventArgs e){this.pIndex 1;ReadLsitT();}/// summary/// 首页/// /summary/// param namesender/param/// param namee/paramprivate void btnFirst_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){e.Handled true;}#endregion
上一页按钮 #region 上一页/// summary/// 上一页/// /summary/// param namesender/param/// param namee/paramprivate void btnPrev_Click(object sender, System.EventArgs e){if (this.pIndex 1)return;this.pIndex--;ReadLsitT();}/// summary/// 上一页/// /summary/// param namesender/param/// param namee/paramprivate void btnPrev_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){e.Handled true;}#endregion
下一页按钮 #region 下一页/// summary/// 下一页/// /summary/// param namesender/param/// param namee/paramprivate void btnNext_Click(object sender, System.EventArgs e){if (this.pIndex this.MaxIndex)return;this.pIndex;ReadLsitT();}/// summary/// 下一页/// /summary/// param namesender/param/// param namee/paramprivate void btnNext_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){e.Handled true;}#endregion
末尾按钮 #region 未页/// summary/// 未页/// /summary/// param namesender/param/// param namee/paramprivate void btnLast_Click(object sender, System.EventArgs e){this.pIndex this.MaxIndex;ReadLsitT();}/// summary/// 未页/// /summary/// param namesender/param/// param namee/paramprivate void btnLast_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){e.Handled true;}#endregion
画每页显示等数据 #region 画每页显示等数据/// summary/// 画每页显示等数据/// /summaryprivate void DisplayPagingInfo(){if (this.pIndex 1){this.btnPrev.IsEnabled false;this.btnFirst.IsEnabled false;}else{this.btnPrev.IsEnabled true;this.btnFirst.IsEnabled true;}if (this.pIndex this.MaxIndex){this.btnNext.IsEnabled false;this.btnLast.IsEnabled false;}else{this.btnNext.IsEnabled true;this.btnLast.IsEnabled true;}this.tbkRecords.Text string.Format(每页{0}条/共{1}条, this.pageNum, this.allNum);int first (this.pIndex - 4) 0 ? (this.pIndex - 4) : 1;int last (first 9) this.MaxIndex ? this.MaxIndex : (first 9);this.grid.Children.Clear();for (int i first; i last; i){ColumnDefinition cdf new ColumnDefinition();this.grid.ColumnDefinitions.Add(cdf);TextBlock tbl new TextBlock();tbl.Text i.ToString();tbl.Style FindResource(FancyTextBlockStyle3) as Style;tbl.MouseLeftButtonUp new MouseButtonEventHandler(tbl_MouseLeftButtonUp);tbl.MouseLeftButtonDown new MouseButtonEventHandler(tbl_MouseLeftButtonDown);if (i this.pIndex)tbl.IsEnabled false;Grid.SetColumn(tbl, this.grid.ColumnDefinitions.Count - 1);Grid.SetRow(tbl, 0);this.grid.Children.Add(tbl);}}#endregion
每页显示多少条 #region 每页显示多少条.private void comInt_PreviewMouseDown(object sender, MouseButtonEventArgs e){// 获取点击的 ComboBoxItemComboBoxItem clickedItem FindAncestorComboBoxItem((DependencyObject)e.OriginalSource);if (clickedItem ! null){// 获取点击项的内容显示的文本string clickedText clickedItem.Content.ToString();this.pageNum int.Parse(clickedText);SetMaxIndexList();ReadLsitT();}}/// summary/// 鼠标点击到combobox选项事件./// /summary/// typeparam nameT/typeparam/// param namecurrent/param/// returns/returnsprivate T FindAncestorT(DependencyObject current) where T : DependencyObject{do{if (current is T ancestor){return ancestor;}current VisualTreeHelper.GetParent(current);}while (current ! null);return null;}#endregion
判断是否为数字的事件 private static Regex RegNumber new Regex(^[0-9]$);#region 判断是否是数字/// summary/// 判断是否是数字/// /summary/// param namevalString/param/// returns/returnspublic static bool IsNumber(string valString){Match m RegNumber.Match(valString);return m.Success;}#endregion
分页数字的点击触发事件 #region 分页数字的点击触发事件private void tbl_MouseLeftButtonUp(object sender, MouseButtonEventArgs e){TextBlock tbl sender as TextBlock;if (tbl null)return;int index int.Parse(tbl.Text.ToString());this.pIndex index;if (index this.MaxIndex)this.pIndex this.MaxIndex;if (index 1)this.pIndex 1;ReadLsitT();}void tbl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e){e.Handled true;}#endregion
跳转到多少页 #region 跳转到多少页/// summary/// 跳转到多少页/// /summary/// param namesender/param/// param namee/paramprivate void btnGo_Click(object sender, RoutedEventArgs e){if (IsNumber(this.pageGo.Text)){int pageNum int.Parse(this.pageGo.Text);if (pageNum 0 pageNum this.MaxIndex){this.pIndex pageNum;ReadLsitT();}else if (pageNum this.MaxIndex){this.pIndex this.MaxIndex;ReadLsitT();}}this.pageGo.Text ;}#endregion
3、泛型数据集合 /// summary/// 定义一个泛型来接受数据/// /summary/// typeparam nameT/typeparam/// param nameparameter/param/// returns/returnspublic void GenericMethodT(ListT parameter){var data parameter;obj parameter.Castobject().ToList();}#region 返回泛型集合/// summary/// 初始化数据./// /summary/// typeparam nameT对象/typeparam/// param namedataGrid数据展示表格/param/// param nameparameter泛型/param/// param nameNum数量/parampublic void ShowPageTT(DataGrid dataGrid, ListT parameter, int Num){if (parameter null || parameter.Count 0)return;if (parameter.Count 0)return;this.grdList dataGrid;this.pageNum Num;this.pIndex 1;obj parameter.Castobject().ToList();SetMaxIndexList();ReadLsitT();if (this.MaxIndex 1){this.pageGo.IsReadOnly false;this.btnGo.IsEnabled true;}}/// summary/// 画数据/// /summarypublic void ReadLsitT(){try{int first this.pageNum * (this.pIndex - 1);first (first 0) ? first : 0;this.grdList.ItemsSource obj.Skip((this.pIndex - 1) * pageNum).Take(pageNum);}catch{MessageBox.Show(错误);}finally{DisplayPagingInfo();}}#endregion
上述的GenericMethod方法已经我这里没用使用你们可以参考使用扩展。
设置页面多少
#region 设置最多大页面/// summary/// 设置最多大页面/// /summarypublic void SetMaxIndexList(){//多少页int Pages this.obj.Count / pageNum;if (this.obj.Count ! (Pages * pageNum)){if (this.obj.Count (Pages * pageNum))Pages--;elsePages;}this.MaxIndex Pages;this.allNum this.obj.Count;}#endregion
4、DataTable数据类型的 #region 初始化数据/// summary/// 初始化数据datatable类型/// /summary/// param namegrd/param/// param namedtt/param/// param nameNum/parampublic void ShowPages(DataGrid grd, DataTable ds,int ss){if (ds null || ds.Rows.Count 0)return;if (ds.Rows.Count 0)return;ds.DefaultView.Sort Date DESC;DataTable dt ds.DefaultView.ToTable();this._dt dt.Clone();this.grdList grd;//this.pageNum Num;this.pIndex 1;foreach (DataRow r in dt.Rows)this._dt.ImportRow(r);SetMaxIndex();ReadDataTable();if (this.MaxIndex 1){this.pageGo.IsReadOnly false;this.btnGo.IsEnabled true;}} #endregion#region 画数据/// summary/// 画数据/// /summaryprivate void ReadDataTable(){try{DataTable tmpTable new DataTable();tmpTable this._dt.Clone();int first this.pageNum * (this.pIndex - 1);first (first 0) ? first : 0;//如果总数量大于每页显示数量if (this._dt.Rows.Count this.pageNum * this.pIndex){for (int i first; i pageNum * this.pIndex; i)tmpTable.ImportRow(this._dt.Rows[i]);}else{for (int i first; i this._dt.Rows.Count; i)tmpTable.ImportRow(this._dt.Rows[i]);}this.grdList.ItemsSource tmpTable.DefaultView;tmpTable.Dispose();}catch{MessageBox.Show(错误);}finally{DisplayPagingInfo();}}#endregion5、用户组件初始化 this.Loaded delegate{//首页this.btnFirst.MouseLeftButtonUp new MouseButtonEventHandler(btnFirst_Click);this.btnFirst.MouseLeftButtonDown new MouseButtonEventHandler(btnFirst_MouseLeftButtonDown);//上一页this.btnPrev.MouseLeftButtonUp new MouseButtonEventHandler(btnPrev_Click);this.btnPrev.MouseLeftButtonDown new MouseButtonEventHandler(btnPrev_MouseLeftButtonDown);//下一页this.btnNext.MouseLeftButtonUp new MouseButtonEventHandler(btnNext_Click);this.btnNext.MouseLeftButtonDown new MouseButtonEventHandler(btnNext_MouseLeftButtonDown);//末页this.btnLast.MouseLeftButtonUp new MouseButtonEventHandler(btnLast_Click);this.btnLast.MouseLeftButtonDown new MouseButtonEventHandler(btnLast_MouseLeftButtonDown);this.btnGo.Click new RoutedEventHandler(btnGo_Click);};
五、效果及使用方法
使用方法
这是我只展示泛型的使用方法
public void LogData(){try{LogDal logDal new LogDal();GlobalVariable.GlobalLog logDal.QueryByIdLogTable().OrderByDescending(m m.Date).ToList();this.Page.ShowPage1(this.logDataGrid, GlobalVariable.GlobalLog, 20); //这里是调用设置分页的函数}catch (Exception ex){throw ex;}}
只需要把你数据源和数据显示datagrid传递过去即可填写一个默认的每页显示的条数。 别忘了引用你的用户组卷目录。
效果 总结
到此分享结束源代码都在文章中简单整理即可使用。分享及随缘下次什么时候分享看缘分吧。
