We have the Auto-hide task bar unchecked. When my window is displayed, the bottom portion is hidden behind the taskbar. Is there a way to avoid this problem and let my form be fully displayed?
I tried setting the "TopMost" property to True, but then every other window is displayed behind my window. i.e. you can not display any other window such as outlook once my window is displayed, they all pop up behind my window.
What other options do I have?

Like ASP.NET/web form, do the windows form also have validation controls?
If not wht is the alternative option?
Thanks

I think they do, but either way, the obvious option is to have a label and write text to check if required values are present.

Don't you have to allocate screen space for labels in Windows Forms? What I am doing on my app is using a custom ValidateInput() method to check all my required fields/check for valid data, then create an error message based on what's wrong and display that to the user in a Dialog window.

Yes, it's the easy option. But I find it's hard to test when you follow TDD. I do this in other way by using ErrorProvider control and using data binding features of the input controls. Please take a look at this[^] article, it's worth reading.

ASP.NET validation controls can't be used with windows forms. You have to take a look at using IDataErrorInfo interface and it's relationship with ErrorProvider control. Use data binding features of the controls, bind your business objects with it. If it implements, IDatErrorInfo, it can validate and show the error provider for the respective controls. Take a look at here[^]

Hi all,

Hi Ashwini,
You may try the following code snippet on Click event of Add Button:
BEGIN CODE
DataGridView1.Item(RowIndex, ColIndex).Value = Me.TextBox1.Text
Or
DataGridView1.Item(RowIndex, ColIndex).Value = Me.ComboBox1.Text
END CODE
Hope this help

I've tried searching to see if this question has been asked before, but the search is not working for some reason.
Does anybody know of an easy way to detect if a displayed record has been altered by the user? When we display a screen to the user with data from the DB, we want to know if they have altered any data so if they close the screen without saving we can prompt them to save. My first though was to wire up each control's "value changed" event and set a custom property to show that the record had been altered. That's not bad except I've got an average of 30 controls per form and am dealing with around 20 forms. There's got to be an easier way. Is there some kind of form-wide "value change" event that I can catch?

There is.

No. But if you used DataBinding then the Data Source you are bound to would actually keep track and you can use a method/property of the DataSource to find out if it has been modified.

Is there some reason you are not using controls like tree/list/grid/PropertyGrid? These can greatly reduce the number of forms and controls needed to allow users to modify data.

I'm curious as to how this would work. I did a datagrid once that I bound to a table in a DataSet and kept track of modifications that way. That was thrown back into my face by the standards review committee at work. They said we don't do data binding on controls but specifically set their text based on fields contained in a "business" object. I haven't used data binding since. I'll do some looking on this and see what I can figure out. Thanks.
The forms I'm dealing with are mainly contract detail forms. There are tons of fields in the contracts and each field has its own field in the record. When the detail is displayed, each field has to have its own control.

You can bind to a "business" object, and have the business object keep track of changes (by having a _old value).
DataBinding has their pro and con
Pro: You get to have the value changed in business object as soon as the value is changed.
Con: Due to the pro, sometime you need to be very careful of the sequence of change, especially is the changes triggers calculation which trigger changes, etc
Setting and Saving values manually
Pro: Doesn't has the DataBinding con:
Con: Quite a lot con. Data changes is not populated back to the BO, so you may have code that manually repopulate part of the data to do some processing, aka, data out of sync between UI and BO.

Well, think about what's on a contract. Just the first little section, purchaser's Last Name, First Name, Address 1, Address 2, City, State, Zip-Code, Home Phone, Work Phone, Cell Phone is 10 textbox controls. Plus, this is taking the place of a very old Access application and the end users are very adament about it looking exactly like what they currently have.

Or 1 PropertyGrid control.  You can edit almost any data using a single PropertyGrid control. Furthermore you can use things like trees etc., to navigate the hierarchy of your data and at each navigation point you can edit that subset of the data in the same PropertyGrid control. Do you use Visual Studio? Did you not notice how the same control provides editing for all the data in your project?

Sorry, I don't know anything about PropertyGrids. This is the first Windows app ever developed by my company (and it's for internal use only). Furthermore, this is the first coding project I've been involved with. Up until now my career as a "programmer" (programmer in title only) has been limited to writing documentation for old web apps. But I'm enjoying my freedom with this one. I'm learning a lot.

A code-saving technique that few developers seem to be aware of is that you can wire multiple events to a single event handler. You can make each control's Changed event call the same function.
Visual Studio's designers don't make this very easy, but you can enter the same function name in the Events part of the Properties pane for each control.
