NO, I want to modify the setting of 'Trigger Control' in the control panel in CE.

Hi,
I need to turn OFF the HTMLEncode property of a GridView Column dynamically i.e. when I'm reading from a Chinese database, i need to show "GB2312 Charset" characters.
I'm binding the GridView dynamically in code behind by its DataSource property. The only place where i could find access to the HTMLEncode property is when you explicitly create a Bound field (which i don't want to do). How do I turn off the HTMLEncode property of a Column in a GridView programatically??
Any help would be appreciated.
(if anyone knows how to display GB2312 characters in a Gridview by some other way ,that would be great too  )
Thank you
Sanjot.

Hello,
I need a textbox control that operates like the "To" control in many email programs, (Outlook etc). I've had a good look around, but can't seem to spot one anywhere. I know I've posted this in General Discussions, but haven't received a response there. Sorry for the cross post.
If you understand how the To: or CC: etc controls in an Outlook New Mail operates, then you've basically got the requirements right there. It displays a list of objects, each represented by some underlined text. You can select, double click on the object's text, and it will display more information etc. You can drag and drop them between two similar controls (eg. from To to CC etc). Most importantly, you can't split up the text of an object - to the user, the text IS the object
I've got a good start on developing such a control, but I'm concerned about the full amount of support required for it. For example, undoing, intellitext etc. etc.
Thanks in advance for any help or pointers
Phil

This is definately something you need to write yourself. Undo is easy, just keep a history of what the user types in a list

Well i've almost go this treeview finished, it looks good now, got icons for different types of nodes, but when i click on a node, its icon gets changed to that of imageindex 0, and when i click another it changes back.
I don't know why it's doing this, but is kind of annoying, its not a priority or anything so...

Hello
TreeNode.ImgageIndex => Unselected state (You've done that!)
TreeNode.SelectedImageIndex => Selected state (You've forgot that!)

Aww, that means more effort.
Well thanks, you've saved quite a bit of time there.

Well i got this:
void TreeView1AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
this.treeView1.SelectedImageIndex = this.treeView1.SelectedNode.ImageIndex;
}
but it redraws the whole treeview (redraw, not rebuild) with a nasty flash, every time the SelectedImageIndex is changed, any way around this?
or do i just have to find another icon for the SelectedImageIndex?

Hello
You should set the images when initializing the treeview for the first time only, not every time you select/unselect a node. Do this in your form's constructor, or the Form_Load event handler.
Besides you set the TreeNode.SelectedImageIndex, not TreeView.SelectedImageIndex. The latter is the default image displayed for any selected node, if the node doesn't have an images -will work fine if you have only one image for all selected nodes-.

Hi,
Does anyone knwo what the IsRequired property is supposed to do for the ConfigurationProperty attribute? If i omit a required property in the configuration file, it doesn't throw an exception nor does it go into OnRequiredPropertyNotFound -- what does setting IsRequired to true do then?
Thank you!

I know this sounds noob, but I'm missing something here and I can't figure out what.
I have a class (we'll call it myControl) that inherits from System.Windows.Forms.Control.
In myControl, I override OnPaint.
I then add an instance of myControl to a Panel, hoping to see it there. However, it doesn't show up. What am I forgetting?

Nevermind. I guess you can't set a Control's size in its own constructor (or, can you?). Anyway, I guess I need to look over my math...
Thanks anyway!

Sure you can!! Why not?

I guess you can after all. My math was wrong with what I was drawing, so I was drawing stuff outside the bounds of the control.

Is it visible ? I'd expect to see it, too.

Hello,
Maybe you forgot to path, the base.OnPaint(..) in your "overrided"??? OnPaint Method.
All the best,

Hi,
I'm having troubles finding information about drag&drop support for tray icons. I know you can drag&drop on a lot of controls in C#, but the events are not listed for the "notifyicon" (aka tray icon).
Has anyone tried this before ? Google didn't really help me on the matter either.

|

Hello
I guess you should handle the NotifyIcon.MouseUp event, but where to go from there is up to you
Regards
|
|
|
|
|
I don't think that'll work since you need to have something like the "DragEventArgs" to see which data is being drag&dropped.
And I don't know that much about changing controls to implement that into the notifyicon control
