c# WinForm 编程总结

1、清空DataGridView

 1 /// <summary>
 2         /// 清空DataGridView
 3         /// </summary>
 4         /// <param name="dg">DataGridView</param>
 5         public void ClearDataGridView(DataGridView dg)
 6         {
 7             try
 8             {
 9                 if (dg == null || dg.DataSource == null)
10                 {
11                     return;
12                 }
13
14                 DataTable dt = (DataTable)dg.DataSource;
15
16                 dt.Rows.Clear();
17
18                 dg.DataSource = dt;
19
20             }
21             catch (Exception e)
22             {
23                 string errorMsg = string.Format(@"清除{0} DataGridView数据时出错，错误原因：{1}", dg.Name, e.Message);
24
25                 Platform.Log(LogLevel.Fatal, errorMsg);
26
27                 AlifMessageBoxShowError(errorMsg);
28             }
29         }

2、清空C1FlexGrid

 1 /// <summary>
 2         /// 清空C1FlexGrid
 3         /// </summary>
 4         /// <param name="c1FG">C1FlexGrid</param>
 5         public void ClearC1FlexGrid(C1.Win.C1FlexGrid.C1FlexGrid c1FG)
 6         {
 7             try
 8             {
 9                 if (c1FG != null)
10                 {
11                     c1FG.Clear(C1.Win.C1FlexGrid.ClearFlags.Content);
12                 }
13             }
14             catch (Exception e)
15             {
16                 string errorMsg = string.Format(@"清空{0} C1.Win.C1FlexGrid.C1FlexGrid数据时出错，错误原因：{1}", c1FG.Name, e.Message);
17
18                 Platform.Log(LogLevel.Fatal, errorMsg);
19
20                 AlifMessageBoxShowError(errorMsg);
21             }
22         }
