BindingSource CancelEdit问题 [英] BindingSource CancelEdit Problem

问题描述

我在winform C＃应用程序中使用了绑定源。

我对其他表格和表格没有任何问题。

但现在我无法解决我的问题问题：

My Binding是：

BindingSource BS_ART = new BindingSource（Parametres.DS_GESPI，ARTs）;

BS_ART.CancelEdit（ ）在控件绑定后不起作用。当我在Create Void之前测试它时，它运行良好。但是我无法理解。

我的控件的绑定是：

我正在使用一个名为TextBoxCalcul的用户控件，其中有一个名为TEXTBOX_AVEC_CALCULATRICE的TextBox。 br $>

I'm using the Binding source in my winform C# application.
I had no problems with other Forms and Tables.
But now i can't solve my problem:
My Binding is :
BindingSource BS_ART = new BindingSource(Parametres.DS_GESPI, "ARTs");
the BS_ART.CancelEdit() doesn't work after the controls bindings. When I test it before the Create Void, it's well working. But I' can't understand.
The bindings to my controls is:
I'm using a usercontrol named TextBoxCalcul where there is into it a TextBox named TEXTBOX_AVEC_CALCULATRICE.

推荐答案

我找到了解决方案：

对于Checkboxes上的绑定，我们必须添加：

，true，DataSourceUpdateMode.Never））;

示例：



FartcheckBoxACTIF.DataBindings.Add （new Binding（Checked，BS_ART，Parametres.DS_GESPI.Tables [ARTs]。Columns [ACTIF_ART]。ToString（），true，DataSourceUpdateMode.Never））;

I found the solution:
For the bindings on Checkboxes we have to add:
, true, DataSourceUpdateMode.Never));
Example:

FartcheckBoxACTIF.DataBindings.Add(new Binding("Checked", BS_ART, Parametres.DS_GESPI.Tables["ARTs"].Columns["ACTIF_ART"].ToString(), true, DataSourceUpdateMode.Never));
