If you see the bindingsource runtime, this user guide should help. The BindingSource part is intended to make it easier to manage the binding controls to the underlying data source. It provides a nice web link abstraction of your form data when routing commands to the person’s underlying data list.
I have good reason for a Winforms application to have a BindingSource bean and its DataSource to define the DataSource that I first created for the custom info object. It also shows several controls related to the various properties of the part provided by the BindingSource. Many of these controls are combo boxes and display values using enum padding, so I defined the data source for these controls as follows:
comboBox1.DataSource = new BindingSource(Utility.ToList(typeof(DataObject.EnumValues)), null); comboBox1.DisplayMember = "Value"; comboBox1.ValueMember is equal to "Key";
This all works fine, but I have two combo boxes and I also need the performance to change at runtime to display multiple different values (with different enum). In both of these cases, I create initial bindings in addition to the data source in the following code:
comboBox2.DataBindings.Add(new Binding("SelectedValue", this.bindingSource, "PropertyName1", true)); comboBox2.DataSource equals new BindingSource(Utility.ToList(typeof(DataObject.FirstSetOfEnumValues)), null); comboBox2.= Flag "Value"; comboBox2.ValueMember implies "key";
… and then when I need a ComboBox2 to be bound to different characters and displayed, I do this:
ComboBox2.DataBindings. Purely(); comboBox2.DataBindings.Add(new Binding("SelectedValue", this.bindingSource, True)); "property_name2", comboBox2.DataSource = null; comboBox2.DataSource equals new BindingSource(Utility.ToList(typeof(DataObject.SecondSetOfEnumValues)), null); comboBox2.= Flag "Value"; comboBox2.ValueMember = "Key";
I can say that doing law is the most rewarding thing, but it’s ugly and there should now be a much better way to do it, ideally? If you know what this thought is, I would like to hear this tool! Thank you!
What is the purpose of binding source in Ado net BindingSource source new BindingSource ();?
The BindingSource component serves several purposes. First, it makes it easy to bind contact form controls to data by providing currency management, change notification, and other services to Windows Forms controls and computer file sources.
In the Visual Studio 2005 designer, I have a grid, an anchor reason, and a
A dataset containing double data tables.
In the designer, I make the settings below. If I change DataMember to

For a binding source that supportsthere is no you in table 2, I see the data in table 2. Everything works
I should be able to remap the DataMember for the binding power source to

Has anyone been able to swap the DataMember destinations for the binding
source at runtime? If yes, is there any reminder I missed?
myGrid.DataSource = myBindingSource.
myBindingSource.DataSource is equivalent to myDataSet
myBindingSource.DataMember = myDataSet.Table1
myBindingSource.DataMember means myDataSet.Table2
