In my PropertyGrid I have a combobox with a large amount of items. For filtering purposes I am trying to implement a combobox WITHIN the PropertyGrid that has an internet explorer address comboxbox behaviour, that is, as the user types into the combobox, the dropdown part is opening and the items are filtered alphabetically (according to the typed letters). For example, the user types "go" into the combobox field and the unterlying list items are limited to items that start with "go".
I tried 2 ways already: 1) derive from UITypeEditor and 2) implement a TypeConverter with StandardValuesSupported. In both ways I can nicely display the combobox but I did not find a way to extract the combobox control and to access it in any way. Any suggestions?

Hi,
why do you need to access the dropdown box if your TypeConverter is able to supply the right strings to be displayed...
|
|
|
|
|
So, how would you implement my requested feature using the TypeConverter?
|
|
|
|

well, if you answer a question by another question, it will be difficult to help. The reason I intervened is because I implemented such a feature in Smart PropertyGrid. But the framework is really different from the MS PropertyGrid so it may be difficult to implement it. Since you said you were successful in 1. the UITypeEditor and 2. the TypeConverter, I was unable to see why you needed access to the dropdown part of the combo... Also how did you do to intercept the keys typed in the textbox to restrict the possible values of the converter ? Did you succeed ? If I know where and why you feel stuck, I may be able to help...

Sorry, my first comment might have been misleading. I was NOT successful in implementing a combobox which drops down on typing keys into it (like the IE url-address text field). I implemented a regular combobox where the user is able to select an item from the list, but he is not able to type his own string. However, I can intercept the keys in the textbox by something like this:
<code>
private TextBox m_Textbox;
foreach (Control control in _propertyGrid.ActiveControl.Controls)
{
if (control.GetType().ToString() == "System.Windows.Forms.PropertyGridInternal.PropertyGridView+GridViewEdit")
{
if (control is TextBox)
{
m_TextBox = control as TextBox;
break;
}
}
}
</code>
This is how I access the text box in the PropertyGrid. Then I can attach the TextChanged event to the textbox and intercept the keys typed in. Now - as the user types his keys - I want the combobox to drop down and automatically restrict the values. Does this make sense to you?

OK, I see now, except that I'm not sure if you implemented your own UITypeEditor or not. Anyway, using your own one or the default one, you won't be able to show the dropdown box and at the same time to have the focus in the textbox to let the user continue typing. This is even the same in Smart PropertyGrid. So how did I implement it in SPG ? I used the autocompletetion feature of the textbox. It looks something like that in my code:
string[] displayedValues = propEnum.Property.Value.GetDisplayedValues();
if (displayedValues.Length > 0)
{
System.Windows.Forms.AutoCompleteStringCollection coll = new System.Windows.Forms.AutoCompleteStringCollection();
coll.AddRange(displayedValues);
tb.AutoCompleteCustomSource = coll;
tb.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;
tb.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend;
}
tb is the textbox, so since you have a hack to get access to your textbox, you could maybe do the same. I can assure you that this a waste of time to try to do it with the UITypeEditor in the MS PropertyGrid.

Oh dear, I think I have a lot of troubles dealing with common controls today..
tabControl1.SelectedTab.Font = new Font("Tahoma", (float)8.25, FontStyle.Bold);
The above line is simply not working! May I know how do you manage to do it?? "Changing the currently selected tabpage font"

Hello Muammar,
The Font of the Text you see in the Tab Selection is not a member of the TabPage itselve.
It is a member of the TabControl.
So if you set the Font property of the TabControl, all the TabPage writers will change.
If you whant to chenge only one (the active one), you better inherit you own TabControl and:
1)Set "this.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed;" in the Constructor
2)override OnDrawItem:
protected override void OnDrawItem(DrawItemEventArgs e)
3)set a Font variable accordingly to EventArgs index:
Font actFont;
if(e.Index != this.SelectedIndex)
{
actFont = e.Font;
}
else
{
actFont = new Font("Tahoma", (float)8.25, FontStyle.Bold);
}
4)write the Text (using System.Drawing)
using(StringFormat sf = new StringFormat())
{
sf.Alignment = StringAlignment.Center;
e.Graphics.DrawString(this.TabPages[e.Index].Text, actFont, Brushes.Black, e.Bounds, sf);
}
Hope it helps!
All the best,
Martin

Good evening truly people,
With all due respect, may I know how HOW THE HELL do I get a node selected using the right mouse button and then show the context menu..
I'm trying this
private void tree_Level_MouseDown(object sender, MouseEventArgs e)
{
tree_Level1.GetChildAtPoint(tree_Level.PointToClient(new Point(e.X, e.Y)).Select();
}
Then I managed to show the context menu but once that happens, it goes back and selects the old node

Use the AfterSelect event instead.

Hi Pete and thanks for the help.. Actually, it was already in the AfterSelect event and I had to move it to obtain the mouse location value form the passed arguments. If you tried to run the piece of code I just pasted, it will simply not work anywhere not just out of the AfterSelect event!

In the NodeMouseClick event:
treeview.SelectedNode = treeview.GetNodeAt(e.Location);

Hey! Thanx a bunch buddy, that was a great help!

Hi,
In my VS2005 Add-in i need the constructor and classname from a cs file. Now i run through all the lines of the file looking for a line containing "class" and not commented ofcours, but i was wondering if there is another way using the projectitem.document?
thx
Kurt

Just parse through them. Maybe use regular expressions

I was just wondering,..
if the VS studio editor could recognize them and mark them with a color, maybe the functionality is available also on the projectitem.documents. So i guess the parsing already exists but how can we use them?

i know the meaning
now i implemented it in the project
using the following code
protected void Page_Load(object sender, EventArgs e)
{
Session["Sonia"] = "11";
Session["Sonia1"] = "12";
Session.Abandon();
foreach (string ste in Session.Keys)
{
Response.Write(ste + ":" + Session[ste]);
}
}
initially i used the two session variables.
if i use the session.clear()
it leave me with 0 session count
but the session vaiables remain the same if using the sesssion.abandon()

Session.Abandon lets you access the session variables until the page goes out of scope (e.g. you redirect the user to another page). Session.Clear removes the variables instantly.
