Hi everybody,
I'm trying to get a class to appear in a property grid control, and I can do all the basic stuff (assign descriptions to properties etc and get the object to appear in the property grid), however I also want a more complex form to pop up when I click on a more complex property.
Not sure if the above makes sense (if I knew the correct word for what I'm looking for I would have found it on Google by now!), so an example to help:
For example, a font dialog appears when changing the font on a control, by clicking on "..." in the Properties window next to "font"
What I want is to have a property which when clicked gives a "..." button, and when clicked pops up a form to help the programmer/user to set up the object properties.
Hopefully this makes some sense to somebody.
Any help would be appreciated.
Thanks,
Chris

Look at TypeConverter and UITypeEditor 
|

UITypeEditor seems to be exactly what I need!
Thanks (esp for the quick reply!),

I know of ways to format text in a BoundColumn to decimals, numbers, etc but what I am after is a way of passing the text in a cell to a method I have created. Is there a way of doing this?
Many thanks.

Hello,
Could you explain your requirement on how and when you wish to pass the value to your
method. Is there any specific action after you wish to pass the data. The normal procedure
to pass the data could be in either of the given forms. For example:
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
<br />
<br />
<br />
int row, col;<br />
row = 3;<br />
col = 2;<br />
<br />
mymethod(this.dataGridView1[col, row].Value); <br />
<br />
}<br />
public void mymethod(Object obj)<br />
{<br />
MessageBox.Show(obj.ToString());<br />
}
I hope this helps.
Regards,
Allen

What I wish for is a method to be called each time a row is created that will take the text in a specific column and convert it.
Table:
Row Name Id
1 Ric 123
2 Lou 456
3 Matt 789
As a row is created a method takes the Id, runs it through a custom method I have (for converting ID's into Usernames) and then displays the username instead. I am using a SPGridView (SharePoint Grid View).
|
|
|
|
|
I think there is an event called OnItemDatabound that gets called for every row as they are populated.

Hi All,
I created a web application which creates(for the first time) and writes to a log file using Log4Net tool.
Now my requirement is to clean the data for 60 days old log data.
Can any tell me how to do this.
Thanks in advance,
urs friend

Did you look if Log4Net havent got this option already?
|
|
|
|
|
Thanks for the response
but i did not find the option in log4net ( i am new to log4net)
|
|
|
|

If you set your log file to be a rolling file appender, then you could just archive off any data in a log file that is older than 60 days.

Can you explain how to set(or what are the settings need to be set) the log file to be a rolling appender, to archive the data in a log file which is older than 60 days
Thanks,

I have a method which takes a DataRow as an out argument. The method fills out the DataRow with data, and returns it.
So,
public CreateTheFancyTable()
{
DataTable dt = new DataTable();
DataColumn dc1 = new DataColumn("First_Column", System.Int32);
DataColumn dc2 = new DataColumn("Second_Column", System.String);
dc1.AllowDBNull = false;
dc2.AlllowDBNull = false;
DataRow dr = dt.NewRow();
bool fSucceeded = FillOutMyRow(dr);
}
public bool FillOutMyRow(DataRow dr)
{
dr["First_Column"] = 1;
dr["Second_Column"] = "";
}
Please don't focus on the bugs in my quick sample here, the real code is a lot more complex than this.
Now, the last line is going to fail, because dt.Columns[dc2].AllowDBNull is false.
How, in the code of FillOutMyRow(), can I find out the properties of the columns in the row that was passed to me? I only know how to get the column properties of a table, and I don't have the table.
Can I refer directly to the column properties of a row (and if so, how?)? Or do I need to get the parent container of the row (the table), and if so, how?
Thanks,
Joe

DataRow has a Table property.
|
|
|
|
|
Thanks for the help. Of course, I figured that out about 5 seconds after clicking "Post" 
I always assume the more complex answer first (I was starting to research "parent containers" when I noticed Table sitting there...)

 No it wont, you're setting the value to an empty string not DbNull.Value.
Anyway, you should be able to go back to the table/columns from the datarow.
dr.Table.Columns
so you could do if(dr.Table.Columns["Second_Column"].AllowDBNull) { ... }
|
|
|
|
|
Meanwhile, I'm stuck on the fact that I can't test the passed in DataRow to see if it's null or not..
given
public bool FillOutMyRow(out DataRow dr)
{
if (dr == null)
{
return false;
}
dr["first_column"] = 1;
return true;
}
The compiler is complaining: "use of unassigned parameter dr"
What's the problem here?
