.NET Forum / Windows Forms / WinForm General / October 2004control data binding not happening when data entered from app
I have a textbox, which is bound to a class member: textBoxDataServerhostname.DataBindings.Add("Text", localOptions, "DataServerHostname"); The text can be entered by the user, or sometimes generated from code, for example: textBoxDataServerhostname.Text = anotherTextBox.Text; When text is entered by the user, the class member is updated correctly; when it's generated from code, the member is unchanged. How do i get this to work (I want the member to change when the textbox is changed from code)? I have tried setting Modified = true, and setting ReadOnly = false (in the case where the text is generated by code, the control is read only). Thanks in advance for any help... Try adding this line of code after setting the text throught code textBoxServerhostname.Bindings["Text"].BindingManagerBase.EndCurrentEdit(); Sijin Joseph http://www.indiangeek.net http://weblogs.asp.net/sjoseph > I have a textbox, which is bound to a class member: > [quoted text clipped - 15 lines] > > Thanks in advance for any help...

Cheers... for anyone reading this thread who is as paste-happy as me: textBoxDataServerhostname.DataBindings["Text"].BindingManagerBase.EndCurrentEdit(); So... anyone game to explain the underlying reason why this is the case? > Try adding this line of code after setting the text throught code > [quoted text clipped - 23 lines] > > > > Thanks in advance for any help... Another less critical question... All the controls on the form are bound like so: textBoxDataServerhostname.DataBindings.Add("Text", localOptions, "DataServerHostname"); numericUpDownPort.DataBindings.Add("Value", localOptions, "Port"); [etc] Is there a way, (e.g.) when the form is closed, to EndCurrentEdit on all of them? e.g. something like: Formclass.BindingContext.EndCurrentEdit() Should I be setting up the bindings in a different way to make an operation like that possible? cheeeers again, Rua HM. > That has gotta be a record!

Well the thing is, that the data gets sent to the source only when EndCurrentEdit() is called. Typically this gets called in the OnValidating() event of the control when you move focus away from the control. Try moving focus away from the control and see if the data gets commited, you may also use reflection to call the control.OnValidating() method to get a similar effect.
