Here are some methods that you can use
SelectNextControl
GetNextControl
I don't know if they will scroll the form to the control or not. Use the ScrollControlIntoView method to scroll to the desired control.

I'm finishing(some small issues to solve) c# RTP implementation, off course compiled dll can be used in vb.net too.
Before releasing all code in codeproject, i'm looking testers, also if some volunteers to write some docs or contributing in coming article, let me know.

I think you'll find that the language support has to be installed. There's a whole load of code pages and things thtat different langauges need. So unless they are fully installed, they can't properly be installed.

Japanese, specifically, I know needs special fonts as well and everything needs to be unicode based for it to work.

Panic, Chaos, Destruction.
My work here is done.

Hi all,

I read a file and send streams to another method. It's working fine. But all messages are feeding very quickly. So I want to delay within each message. So I do the following

public void ReadFile()<br />
{<br />
  // Do the processing of the file and get the stream<br />
<br />
  Thread.Sleep(20);<br />
<br />
  AnotherMethod(stream); // Sen to another method<br />
}

All those things start on a button click event. Once started the process, my GUI get freeze until finish the process. After that I can drag it and so on. Without the thread I use, there is no any issue.

Can someone tell me what should I do to fix this.

Thanks a lot.

I appreciate your help all the time...

Problem is you are running the file streaming and sending in the same thread where UI is hosted. Create a new thread and execute the job on it. If you need to update UI from this thread, use Invoke/BeginInvoke. You can also use BackgroundWorker class which makes all these easy.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Yes, I read more about threads and found that the issue here is working on the same thread in UI and the process. So I have to do the process in background. Smile | :)

Event handler for check box

Hi all

I have 20 check boxes in my page and i need to fire the checkbox checked event for all check boxes.
Instead of writing the checked event for each and every checkbox is there any way to fire the checked event with only one function.i need to get check box id if it is checked.

I'm doing in C#.Net web application

Thank you.

Write something like this in the constructor or the form's Load event or whatever.

checkBox1.CheckedChanged += checkBox_CheckedChanged // the checkBox_CheckedChanged function
//now handles the CheckedChanged event of checkBox1
checkBox2.CheckedChanged += checkBox_CheckedChanged
checkBox3.CheckedChanged += checkBox_CheckedChanged
//...

Or you can simply set the CheckedChanged handler function from the Properties window (the Events section) for the checkboxes.

And to know which fired the event, it's the sender argument of the handler.

CheckBox Sender = (CheckBox)sender; //unbox to checkbox

Binding to a DataGridView problem

Richard Blythe15-Sep-08 17:33

15-Sep-08 17:33

Hello all,
I just found out that I can't bind a DataGridView to an array of DataRows. The reason for wanting an array of DataRows is because I'm performing so very complex filtering that can't be done with the DataTable.DefaultView object. My question is, why does the datagridview accept a dataTable as a dataSource but won't accept an array of dataRows, even though they contain a reference to the dataTable. Is there a way I can create a custom class that implements IListSource and contains datarows from the dataTable? As you well know, an exception is thrown is you try to add a existing row to another dataTable. I want a memory reference instead of the actual values (DataRow.ItemArray) to save memory overhead.

Thanks,
Richard

I've used up all my sick days, so today I'm calling in dead.

Like what? and how are you filtering it?

The reason i ask is becuase the DataView class is built for filtering from a DataSet, and you can bind it to the DataGridView.

If you really cant use the DataView, why not build your own dataSet up with your DataRow[]? something like....

DataTable table = new DataTable;
foreach(DataRow currentRow in myDataRowArray)
{
    table.Add(currentRow);
}
DataSet.Add(table);

This was done off the top of my head, it might not be 100% correct but the idea of what you need to do is there

Hope this helps

How Do I Force Out ToolTips on DataGridViewCells?

That Asian Guy15-Sep-08 16:57

That Asian Guy

15-Sep-08 16:57

How do I make the tooltip appear on a datagridviewcell (textBox column) even if the user doesn't move their mouse over it and while it is editing.

I am trying to implement a auto-complete feature that will show a tooltip with a match and ask the user to press a key if it is the correct match. It is identical to Visual Studio when one presses form1.FormClosed += and the tooltip box appears with an auto-complete of the event.

Thanks in advance.

Hi,

Actually, you don't need to think about locations and positions, just design your reports, you can use the preprinted form as a background (temporary) for alignments, and the printer will take care about the rest. Hope this will help.
