I have a WinForms app, with each forms having many Text-boxes that bind to a
DataTable.

Associate with each Textbox would be a (text) label. Is there any simple
way such that I can "bind" the Text labels to the TextBoxes, so I can
dynamically set each Label.Text property rather than having to hard-wire the
Label.Text for each Label for textbox?

Hi Patrick,

You can create a custom control to combine in it other controls.

Can you elaborate a little bit more?

I have
1) created a .Net 2TestCustomControl in VS2005
2) Dragged a Label into the Component designer
3) Dragged a Textbox into the Component designer

What I want is to be able to do something like
MyTestControl.DataBinding.Add("Text",myDataTable["myTable"],"myField");

And for the CustomControls Label.Text and TextBox.DataBindings to be updated
automatically.

What code do I have to write within the Custom Control to achieve this?

Hi Patrick,

If you override Text propery of user control (or create another property)
you can put the code to update other controls. Or create two properties for
both databindings.

P> updated automatically.
But, do you want to update other bindings by setting only one?

Where (within the CustomControl) should code to wire up base on the Custom
Property for the Label.Text and TextBox.DataBindings be inserted?

Hi Patrick,

Anywhere add something like.. this (as example):

public void ApplyBinding(DataSet dataSet)
{
DataBindings.Add("TextBox", dataSet, "Table1.Column1");
DataBindings.Add("TextLabel", dataSet, "Table1.Column2");
}, where TextBox and TextLabel are properties onto edit box and label.

Certain example depends on real needs.
