Group: StrataFrame Users Posts: 430, Visits: 507	Iseem to have this fully working now..many thanks for all contributions. I did run into one little issue. When I amneded the SF Source Code for the Inherited textEdit, I 'noticed' that there was not a MaxLength property. So. ok I wrote the code to 'Create' a new Maxlength property in the subclassed TexEdit control. Of course this made no difference when Iran the code . I then went back and noticed that ther was a Maxlength property already there , but it was in a 'Property' property. Just for lurkers may save a bit of time !!

Take a look at the AutoAdjustMaxLength property and the UpdateMaxLength() method. You can copy that to the TextEdit class in the SF DevExpress Wrapper source, then recompile and all should be good.

Group: StrataFrame Users Posts: 430, Visits: 507	I am trying to SubClass the DevEx TextEdit control and use the AutoAdjustMaxLength property thats in the SF TextBox. If this is now included as standard, could someone point me in the right direction, if not , some pointers to where the code is in the SF Source Code, or if somebody has already done it in C#, that would be very useful

It is not much different than where I started before attempting to recreate the SF code. using MicroFour.StrataFrame.Business; using System; using System.Data; using System.Drawing; namespace Aspire.SubclassedControls.DevEx { public class TextEdit : MicroFour.StrataFrame.UI.Windows.Forms.DevEx.TextEdit { public TextEdit() { InitializeControl(); } private void InitializeControl() { Properties.AppearanceDisabled.BackColor = Color.FromName("Info"); Properties.AppearanceDisabled.ForeColor = Color.FromName("InfoText"); Properties.AppearanceReadOnly.BackColor = Color.FromName("Info"); Properties.AppearanceReadOnly.ForeColor = Color.FromName("InfoText"); } protected override void OnBindingContextChanged(EventArgs e) { base.OnBindingContextChanged(e); if ((BusinessObject != null) && (BindingField != String.Empty)) { if (((BusinessLayer)BusinessObject).FieldDbTypes[BindingField] == DbType.AnsiString) Properties.MaxLength = ((BusinessLayer)BusinessObject).FieldLengths[BindingField]; } } } }

As far as the copy/paste routine....yup, that is what I do. I lose all of the indentation, though. Perhaps, it a Google Chrome thing.

Group: Forum Members Posts: 785, Visits: 3.6K	btw, how do you get your posted code to have the indentation...I knew once how to do it. I've forgotten.

Group: Forum Members Posts: 785, Visits: 3.6K	Thanks for working this out with me. Here is the code that I am using: using MicroFour.StrataFrame.Business; using System; using System.Data; using System.Drawing; namespace Aspire.SubclassedControls.DevEx { public class TextEdit : MicroFour.StrataFrame.UI.Windows.Forms.DevEx.TextEdit { public TextEdit() { InitializeControl(); } private void InitializeControl() { if ((BusinessObject != null) && (BindingField != String.Empty)) { Properties.AppearanceDisabled.BackColor = Color.FromName("Info"); Properties.AppearanceDisabled.ForeColor = Color.FromName("InfoText"); Properties.AppearanceReadOnly.BackColor = Color.FromName("Info"); Properties.AppearanceReadOnly.ForeColor = Color.FromName("InfoText"); if (((BusinessLayer)BusinessObject).FieldDbTypes[BindingField] == DbType.AnsiString) Properties.MaxLength = ((BusinessLayer)BusinessObject).FieldLengths[BindingField]; } } } } Looks quite similar to your's, eh?
