I know several ways to hide individual properties, and in something I'm working on I do it using a Designer, more specifically by overriding the PreFilterProperties method
protected override void PreFilterProperties(System.Collections.IDictionary properties)
{
properties.Remove("Dock");
properties.Remove("TabStop");
properties.Remove("TabIndex");
properties.Remove("Visible");
properties.Remove("Enabled");
properties.Remove("Locked"); <===========================================================
properties.Remove("Anchor");
properties.Remove("Name"); <===========================================================
properties.Remove("AutoSize");
properties.Remove("AutoSizeMode");
properties.Remove("Location");
properties.Remove("Size");
properties.Remove("MaximumSize");
properties.Remove("MinimumSize");
properties.Remove("BorderStyle");
properties.Remove("GenerateMember");
properties.Remove("Modifiers");
properties.Remove("Design");
base.PreFilterProperties(properties);
}
The two properties marked still show up however. 
They are both in the 'Design' Category, so even if the code above worked, I would still be left with an empty Category. So
1) anybody got any ideas about why the two properties remain and/or how to get rid of them.
2) any ideas on how to remove the 'Design' Category. If you look at either of the Panels in a SplitContainer, they don't have a Design Category, so presumably it is possible.

Hello Sir Henry,
my undercover informant told me the secret of SplitContainer panels is in this line:
[EditorBrowsable(EditorBrowsableState.Never), Browsable(false), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
Hope that helps.

Hi Luc,
Thanks for that. I had completely forgotten EditorBrowsable, so this was a useful reminder. Unfortunately these attributes are of no help in my case.
I have discovered, through experimentation and reading the documentation that Locked, certainly, and Name must be guilty by association, is not a Property of Panel, which my class descends from. It therefore must be provided by an Extender Provider in the host designer. I vaguely remember reading this about Name somewhere anyway. So it's another round of googling and reading, unless your good self or A.N. Other has a solution.

I got some more info for you:
1. Locked is not a run-time property of most Controls; only a few (ToolStripPanel) have it.
It seems to exist inside VD only.
2. Name is completely different; it is a property of Control, public and not virtual. It is Browsable(false) so the "(Name)" you see in VD isn't the real thing.
And some specialized controls have their own Name property, not new, not override, not virtual?????
That will be all from me on this subject.

Hello, I'm working on a developing a windows application which displays file names as link labels on a form. The files are saved in an Oracle database table as BLOBs. The files can be of any format .jpg, .gif, .pdf, .tiff, .htm, .pdf, .zip etc. When the user clicks on a link label, I am retrieving the corresponding BLOB from Oracle and have converted into byte array. I'm stuck on how to stream this byte array for the user to save in his desktop. If there is a way to even save and open the file systematically also, that would be great.
Any help from you is greatly appreciated.

You can do this using the FileStream class. Like this:
FileStream oFileStream = new FileStream("FilePath", FileMode.OpenOrCreate);
oFileStream.Write(YourByteArray,0,YourByteArraySize);
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

Hello D@Nish, thank you very much for your response. Is there a way to open the file systematically as soon as the save is complete? Thanks again for your help.
|
|
|
|

Use Process.Start method once the save is complete. It will open the file in the associated program.

Thanks in Advance,
While debugging anything in Visual Studio cannot see in debugging mode that whats going on the application
lets say i have a Text Box control and i wrote code for it
TEXTBOX1.text ="Hello World"
now while debugging i want to see the values on my application that ok it has set this value now or not
Any alternate or suggestion
Best Of Regards ,

The application is halted when it hits a breakpoint. Hence, it will not paint the form.
You can add a "watch" in order to inspect the value though
|
|
|
|
|
Yes you are right but any other way instead of adding watch window because my scenario involves so many controls and grids any how thanks for Helping
|
|
|
|

Call Application.DoEvents() after setting the textbox value.
while (e) { Coyote(); }

Hello All,
I have list that is globally declared and i have add button which will add one object to the list once it clicked .
I am binding this list to grid .
for the first time when i click add button item is added to the list and binded to grid too.
when i again click the same then it added the item to the list but still not reflected to grid and then i have done some modifictions and get the result.
please find the code
private void btnAdd_Click(object sender, EventArgs e)
{
objSapient.Add(new SapientDetails(txtName.Text,txtSapientID.Text,txtProjectName.Text,txtPhoneNumber.Text,txtExpr.Text));
if (objSapient.Count != 0)
{
grvDetails.DataSource = null;
}
grvDetails.DataSource = objSapient;
}
why do i need to set as datasource to null ?
why just grvDetails.DataSource = objSapient; is not sufficeint .
Please tell the reason for the same
|

Not sure about this behaviour.
But to avoid setting the datasource to null, use a BindingSource object to set the datasource of the DataGridView. Set the DataSource of the object as your list. And on button click, just add the item to the BindingSource object. This will add item to both the List and the DataGridView.

When I code a Setter for a property, I usually do it like this
public int SomeProperty
{
get
{
return this.someField;
}
set
{
if (this.someField != value)
{
this.someField = value;
this.Invalidate();
}
}
}
and this is probably what is happening in your case. Setting a field to the value that it already holds, results in nothing actually happening.
To solve your problem you really need to use the more complex version of DataBinding which includes change management. So that changes you make to objSapient are automatically reflected by the binding.
Take a look at the documentation for BindingSource, or Google for complex databinding to objects (or similar)
