将 Infragistics UltraWinGrid 的特定列设置为只读
我陷入了一种情况，除了新添加的行之外，我需要禁用每行中的几列。
也就是说，网格中有 10 列，前 3 列是数据绑定的，并且来自数据库，处于禁用或只读状态。其余的可以编辑。
如果我添加新行，则必须启用新行的所有列，直到保存为止。
我的现有行或新行没有任何 DataKey 或主键。我必须检查一些布尔值，例如 IsNewRow。
在我当前的场景中，我使用此代码块：
Private Sub dgTimeSheet_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles dgTimeSheet.InitializeRow
''if either column key is Project, Class or Milestone
'' Activation.NoEdit = Disable and Activation.AllowEdit = Enable
Dim index As Integer = e.Row.Index
If e.Row.IsAddRow Then
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.AllowEdit
Else
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.NoEdit
End If
CheckRows()
End Sub
问题是，如果我单击禁用/只读行，则新添加的行也会被禁用，这是我不希望的。
I am stuck in a situation where I need to disable a few columns in each row, except for the newly added row.
That is, I have 10 columns in the grid and the first 3 columns are databound and come from the database as disabled or read-only. The rest are editable.
If I add a new row, then all the columns of the new row must be enabled until it is saved.
I don't have any DataKey or primary key for my existing row or the new row. I have to check for some boolean value like IsNewRow.
In my current scenario I am using this code block:
Private Sub dgTimeSheet_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles dgTimeSheet.InitializeRow
''if either column key is Project, Class or Milestone
'' Activation.NoEdit = Disable and Activation.AllowEdit = Enable
Dim index As Integer = e.Row.Index
If e.Row.IsAddRow Then
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.AllowEdit
Else
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.NoEdit
End If
CheckRows()
End Sub
The problem is that if I click on disabled/read-only rows, then newly added rows also get disabled, which I don't want.

我正在与 C# 中的类似问题作斗争，所以这是在黑暗中钓鱼...在您的情况下，是否可以添加 IgnoreRowColActivation = true 语句以防止行恢复？
I am fighting with a similar problem in C#, so this is fishing in the dark... Is it possible, in your case, to add an IgnoreRowColActivation = true statement to keep the rows from reverting?
此示例为客户使用的界面创建只读列，
示例为具有三列的行。将两列设置为只读，将第三列设置为用户可编辑。
设计器中定义的三列：
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn1;
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn2;
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn3;
设置第 1 列和第 1 列2 直接
仍然可以更新源代码中的所有列。客户只能编辑第三列。
This examples create read only columns for the interface a customer uses
Example for a row with three columns. Set two columns as readonly and the third as editable to the user.
the three columns defined in the designer:
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn1;
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn2;
System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn3;
set column 1 & 2 directly
You can still update all columns in the source code. The customer will only be able to edit the third column.
