Workarounds
1. You can redirect user to someother page after clicking add button. Like "Thanks, values saved" is displayed on that page.
2. You can set an session variable, And increment that value, so if that value is set to 1, you can stop the value from entering into db.

I m using dataGrid control in my application. I want user to add records using Data Grid. Right now my Grid has 5 columns. Problem is that if user fills only one column and click add button, Grid does not add that row. Infact if i click on some other control that row from grid just disappeared. But if i fill all colums then a blank row appear down that row. and now if i click add button, this row will be added.
Now i just want a row to be added if i only fill one column. What should i do?

Hello,
This is because the new row has not been committed in the datatable/datasource which you are using with DataGrid. You can write code in CurrentCellChanged event handler to assure that the changes you made in the datagrid are saved when you leave the cell.
HTH. Cheers.

Hi
I hope you will call a function to load the html document on click of the TreeNode. You might be using Treeview_Afterselect or Treeview_click event. What you can do is You can put this code before calling that function.
this.Cursor =Cursors.WaitCursor ;
trv.Enabled=false;
// You will call the function to load html file here
trv.Enabled=true;
this.Cursor =Cursors.Default ;
Hope this helps

I am using Directory.GetFiles to get an array of all the files in a directory. As far as that goes all is well. But, I need to know just the name of the files, not the whole path to the file. I was trying to us RegEx to search each file path and remove the path but I don't know how to do so universally as I don't know the exact path of the files all the time. Any ideas would be great.
Thanks in advance!

Use Path.GetFileName(String path).
In namespace "Path" you can find many usefull functions 
|
|
|
|
|
OR you could just strip the directory info from the names...

I get an error with the compiler each time I try to do this:
public interface IBehavior
{
...
}
public interface IBehaviorActing
{
IBehavior Behavior
{
get;
}
}
public class Behaviorclass : IBehavior
{
...
}
public class Itemclass : IBehaviorActing
{
public Behaviorclass Behavior
{
get {...}
}
}
The compiler say the Itemclass does not implement interface (wrong return type - Meaning not defining explicitly public IBehavior Behavior in Itemclass). Is there a pattern or another way around this?
|
|
|
|

Well, you didn't mention your intention why you want to return Behaviorclass in Itemclass. But I would say that I think you can still do whatever you want, using IBehavior return type (instead of Behaviorclass).
If you want to use the return type as Behaviorclass (instead of IBehavior), you can up-cast it later, like: Behaviorclass bc = SomeInstanceofItemclass.Behavior as Behaviorclass;
Hope it helps

The problem is that the interface says the Property has to be of type IBehavior and not Behaviorclass. To have a typesafe accessor in Itemclass and still adhere to the interface do the following:
public class Itemclass : IBehaviorActing
{
public Behaviorclass Behavior
{
get {...}
}
IBehavior IBehaviorActing.Behavior {
get { this.Behavior; }
}
}
The compiler will call the normal Behavior property whenever you access Behavior via the concrete class. Whenever it is accessed via an interface variable it will access the interface implemenation (which in turn calls the typesafe one).
I regulary use these constructs. It's also extremely useful when working with the ICloneable interface.

I'm having a problem with scaling GIF images down without getting pixelation. I am using HighQualityBicubic interpolation with HighQuality smoothing.
Converting the images to JPG seems to work fine, but saving to their native format produces undesirable image quality.
Any ideas on how I might clear this obstacle?
Thanks,

We're working on a project that goes against another application that exposes it's API via web services. Pretty cool, except for the complexity of actually getting anything done due to the interdependacy of the calls.
So what we're doing is writing wrapper classes to abstract away the details to let people call a simple function that takes care of all the nitty gritty bits. Plus give us the future option of moving to another third party app by simply rewriting the wrappers.
Now for the problem area... we want to hide the actual web service calls from the application programmers using our wrapper. Basically we want to try to prevent someone from going outside the sandbox and using the API directly, potentially causing problems with the app or future portability. With them referenced in the assembly, you can see them by default. I know it's probably basic, but haven't worked out how to make them private or internal.
Someone got a pointer?
