winform DataGridView-----2
上一篇对Data'gridView做了简单的封装,基本能满足正常开发了,后来我发现一个单元中同时会又左边图标右边文字的情况,这次就把这个也加上。所以我自定义歌一个组件。
自定义 DataGridView 组件:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 | public partial class GridList : DataGridView { private Dictionary< int , Image> dic { get ; set ; } public void SetHeader(List<dataGridViewModel> viewModel) { dic = new Dictionary< int , Image>(); this .CellFormatting += Grid_cellFormartting; foreach ( var item in viewModel) { switch (item.colType) { case ColType.文本: this .AutoGenerateColumns = false ; TextAndImageColumn ColumnRoleID = new TextAndImageColumn(); ColumnRoleID.DataPropertyName = item.colName; ColumnRoleID.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft; ColumnRoleID.Name = item.colName; ColumnRoleID.HeaderText = item.colTitle; this .Columns.Add(ColumnRoleID); break ; case ColType.图标: //单独一列显示图标 this .SetImage(); break ; case ColType.图标文本: //单独一列显示图标 SetCellImgOrText(item.cell); break ; case ColType.按钮: this .SetButton(item.TitleData); break ; default : break ; } } } /// <summary> /// 设置图标文字 /// </summary> /// <param name="cellType"></param> private void SetCellImgOrText(CellType cellType) { dic.Add(cellType.ColIndex, cellType.ImageType); } /// <summary> /// 列表添加图片 /// </summary> private void SetImage() { DataGridViewImageColumn Imange = new DataGridViewImageColumn(); Imange.ImageLayout = DataGridViewImageCellLayout.Zoom; // Imange.HeaderText = "图标"; this .Columns.Add(Imange); } /// <summary> /// 列表添加操作按钮 /// </summary> /// <param name="gridView"></param> public void SetButton( Title title) { if (title == null ) { return ; } DataGridViewButtonColumn select = new DataGridViewButtonColumn { Name = title.headTitle, Text = title.Text, UseColumnTextForButtonValue = true , DataPropertyName = "operate" , FillWeight = 5, HeaderText = title.headText }; select .FlatStyle = FlatStyle.Flat; select .Width = 20; select .DefaultCellStyle.ForeColor = string .IsNullOrEmpty(title.color) ?

Model:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | public enum ColType { 文本, 图标, 图标文本, 按钮 } public class dataGridViewModel { public string colName { get ; set ; } public string colTitle { get ; set ; } public ColType colType { get ; set ; } public Title TitleData { get ; set ; } public CellType cell { get ; set ; } } /// <summary> /// 图标,文字 /// </summary> public class CellType { public int ColIndex { get ; set ; } public Image ImageType { get ; set ; } } /// <summary> /// 按钮 /// </summary> public class Title { public string headTitle { get ; set ; } public string Text { get ; set ; } public string headText { get ; set ; } public string color { get ; set ; } } |
实现:
从心编译工程,工具箱中会出现自定义控件:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 | //设置行表头的颜色 //dataGridView_Mark.SetHeadColor("#F5F5F5"); gridList1.SetHeadColor(250, 250, 250); //表头文字颜色 // dataGridView_File2.SetHeadFontColor("#F5F5F5"); gridList1.SetHeadFontColor(95, 95, 95); //行表头文字类型 gridList1.SetHeadFontType( new Font( "楷体" , 8, FontStyle.Bold)); //改变标题的行高 gridList1.SetHeadRowHeight(30); //去除第一列空列 gridList1.SetRowHeadersVisible(); //行占满 gridList1.SetCellRowFull(); //去除最后一行空行 gridList1.SetAllowUserToAddRows(); //标题居中 gridList1.SetHeadCenter(); List<dataGridViewModel> viewModel = new List<dataGridViewModel>() { new dataGridViewModel(){colType=ColType.图标}, new dataGridViewModel(){colName= "title" ,colTitle= "标题" ,colType=ColType.图标文本,cell= new CellType(){ColIndex=2,ImageType=Properties.Resources.excel } }, new dataGridViewModel(){colName= "title1" ,colTitle= "标题" ,colType=ColType.文本}, new dataGridViewModel(){colName= "title2" ,colTitle= "标题" ,colType=ColType.文本}, new dataGridViewModel(){colName= "title3" ,colTitle= "标题" ,colType=ColType.文本}, new dataGridViewModel(){colName= "title4" ,colTitle= "标题" ,colType=ColType.文本}, new dataGridViewModel(){colName= "title5" ,colTitle= "标题" ,colType=ColType.文本}, new dataGridViewModel(){ colType = ColType.按钮,TitleData= new Title(){ headTitle= "btnfile4" ,Text= "按钮" ,headText= "操作" } }, }; gridList1.SetHeader(viewModel); //设置某列隐藏 // dataGridView_ReportList.SetColVisible(new string[] { "PKID", "customer" }); Dictionary< int , int > colWidth = new Dictionary< int , int >() { [0] = 30, [6] = 60, }; ////设置列宽 gridList1.SetColWidth(colWidth); for ( int i = 0; i < 30; i++) { gridList1.Rows.Add(Properties.Resources.excel, "dsf" , "dfsfs" , "dsfsdf" , "dfsf" , "dfsf" , "dfsfs" ); } |
