Hi All,
I want to create a datagrid with 4 columns. The third column should have a combo box and the last column should have a checkbox. Its easy to get the checkbox column but how can I create a combo box column. The combo box should be visible always not only when it is selected.
Can any one tell me, how do I place combo box for each cell in third column of a windows datagrid contorl?
Any help is appriciated. Thanks in advance.
Regards

This is answer is without having VS in front of me and I didn't program ASP.net for some months so my memory of the terminology is a bit rusty.
Turn your datagrid column into <asp:templatecolumn>, then add an
<itemtemplate></itemtemplate> within the itemtemplate you can add your <ASP:DropDownList>, make sure to add the right events to the dropdownlist. If you want to fill the dropdownlist on runtime, you have to hook up to the itemdatabind (or something like that) event, there every row of the datagrid is being filled.

I overlooked the "windows" part in the title.
There is a way, but since I don't have VS in front of me, its kind of hard for me to help you. I believe there is already a .NET object made by somebody that does this. I would use reflector and check how the other columns (checkbox, textbox etc) are made, and then in the same way create a dropdownlist column.

Searching for DataGrid ComboBox[^] gives several results. I think one of those should match your needs.

Hi.
My application opens xml reports from command line, which generated and executed by another C# programm. So I get file from "main args[]" to open. How to make my application to open new document if it is already launched and new commandline command with arguments executed?

When your application opens, indicate it somewhere, like a creating a temporary file, with a well-known name, containing the process id of the currently running instance of your program.
When you execute the command line, your program checks for the presence of the file. If it exists adn the process id it contains is still running, use some interprocess communication to tell it to open the new file, then exit from the new command line.

Don't forget to call Dispose() on the ReportDocument object too.

hi all,
i am trying to load a page in a webbrowser.
how can i be sure that the page i am trying to open is completely loaded ?
then again i want to refresh that page for couple of times. (but it must be loaded completely before each refresh)
how can i check this ?
help please.
thanks in advance,
bye.

Monitor the ProgressChanged event, the DocumentCompleted event isn't that reliable I've found, sometimes kicks in too early. Once you've decided the whole page has loaded then you can refresh it and start monitoring again.

In the solution explorer you can right click on the name of the project and click "Add Reference". I believe that you can also go to the Project item in the menu and select "Add Reference"/

I am making a form that will will Generate a report. It will display the report from the reporting services.
From that form, I have a preview and print buttons. Preview will display the report.
and print will print the report. Printing of reports would be possible even if the report isn't displayed yet.
How will i print the report though it hasn't beens shown yet?
What could be my possible code for it?

Hi I've never really understood the use in this peice of code, ive been told its good practice/programming to use it and its been mentioned it had somthing to do with security but personaly i cannot see why.
<br />
private int x;<br />
public int X()<br />
{<br />
get {x}<br />
set {x = value;}<br />
}<br />
(the code might be slightly wrong doing this on the fly)
whats the use in it though surly unless your only using one of the get or the set you might as well just use a public variable that way u decrease on the code thats needed to be written, compiled and read.
any comments would be apreciated

Yes it is definately good practice. There is a slight mistake in it, it should be
get
{
return x;
}
And no () parentheses after X.
X is called the property of x and the reason it is good practice is because in the GET and SET section you can write code to perform any operation you want. For example, you might have a boolean variable (call it 'ready') in your class and you would only allow users to retrieve the value of x if 'ready' is true. So you could do the following:
get
{
if (ready) return x;
else return 0;
}
The same thing can be applied to the SET section, where you could for instance only allow writing of a value if 'ready' is true:
set
{
if (ready) x = value;
else x=0;
}
Now, if a variable only has a get property, it's said to be read-only. Obvsiously, since you cannot set its value to anything.
I hope this helps a bit.

i realised that you could enter other code into the get and set but i hadn't thought of using it in that way, which makes alot of scence.
but that was well explained thx
so as far as good practice gose its good to use it on a normal variable without any aditional code just so if somone comes along in the futre they dont have to adjust a ton of code?
|
|

|

yes, it is a good idea to always have your class variables as protected or private and expose them to the user by mean of properties.
Another common practice is to have the propery name the same as the variable name but with a capitalized first letter. i.e. roleName and RoleName.

It is just usefull when u want to trace a code where u can use value of 'x' and change value of 'x'. And it is more usefull for large project.
