Greetings,
Does anyone knows how to invoke (programatically) the different dialog boxes that VS has, for example the CellStyle Builder Box or the Add Columns dbox, Edit Columns dbox for the DataGridView, The Items Collection Editor for the Menus?
I know I can use EditorAttribute for properties, but the problem comes when dealing with the DataGridView and its columns, i'm using a PropertyGrid to modify the DGridV at run time but the columns do not appear.
I have this code:
public partial class UserControl1 : DataGridView
{
.....
public new DataGridViewColumnCollection Columns
{
get
{
return base.Columns;
}
}
public DataGridViewColumnCollection MyColumns
{
get
{
return base.Columns;
}
}
......
}
The funny/strange thing is that Columns doesn't show the Editor but MyColumns does show it.
I have done a search for DataGridViewColumnCollectionEditor but i just can't find it. Are these dialog boxes available somehow for developers?
Any hint or orientation is well appreciated.
Thanks

Well after doing more and more research i found that the EditorAttribute is making the difference between both properties, so in order to override it i had to do something like this:
[Editor("", typeof(UITypeEditor))]
public new DataGridViewColumnCollection Columns
{
get
{
return base.Columns;
}
}
But this still does not answer my original question...
Is there a way to use the editor from the code? I guess not...
Any hint or orientation is well appreciated.

Fairly new programmer, please excuse me if this is kinda newbie but I couldn't find an answer by searching. I have a windows form, and I was messing around with its properties. Now when I run it, all the white backgrounds are now transparent(you can move icons on the desktop through them). I need help figuring out how to make them function like default again. Thank you in advance for any help

In design mode, click on your form to select it. In the properies window for the form find the Transparency Key property and set it back to transparent. You must have set it to white instead.

Hi,
I'm curious what control(s) you use when you have a simple data input tasking involving rows and columns when :
1. you are not concerned with data-binding
2. you don't want to use a datagrid
3. you don't want to use a listview and muck about with non-editable run-time sub-items.
In other words you want a bunch of organized input fields, but want a very light-weight implementation. And you do want to use some control or combination of controls; i.e., you do not want to "hand-roll" a custom solution with a fixed number of textboxes in a panel or some such.
thanks, Bill

I am not up to date with the variations of Direct<whatever> but most of it is available to the .NET platform[^]. I imagine there are plenty of articles and tutorials for it.
Also for managed C++ development questions there is a forum titled Managed C++/CLI

I have a little SQL query editor, with a TextBox and a DataGridView, for the query text and the results, respectively. I have these on a SplitContainer. I have no timers, nothing else.
My text in the TextBox keeps disappearing! If I highlight it, it's there, and sometimes when I click in the TextBox, it reappears, but much of the time it remains invisible. Any suggestions as to the cause of this will be most appreciated.

Hi,
maybe something is wrong with your selection colors?
|
|
|
|
|
All standard. Everything else works.

Is your textbox multiline? This can cause no end of fun if you expect single line behaviour.
Alan.

|

|

It is multiline, and large. The text literally just becomes invisible!
|
|
|
|
|
This is quite strange. I deleted and recreated the TextBox in question, with exactly the same configuration, and the problem disappeared.
|

See that come from holding your tongue correctly when adding the textbox. Peice of cake.

Hard to say, based on this. Is there a column in common you can use to do a join ? If not, how do you know which 4 goes with which 1 and 2 ? Is 3 a column in common you can join on ?

If you get the SQL right you will have one table with the two lots of data merged.

What you need is a single query:
select drug_name,drug_no, type
from table1 t1 inner join table2 t2 on t2.type_no = t1.type_no
where table1 is the drug_name/number tabler and table2 is the type_no/type table
and then
dim sql as string="{as shown above}"
cmd.connection= con.....
cmd.commandtext= sql
dataAdapter.fill(dataset,"drug")
txdrug_name.databindings.add("text",dataset,"drug.drug_name")
txdrug_no.databindings.add("text",dataset,"drug.drug_no")
txdrug_type.databindings.add("text",dataset,"drug.type")
Its called a table join. I suggest yuo try reading up on sql, otherwise your application is really going to suffer.
