Dynamic update of comboboxes in datagrid

Atlemann2-Aug-05 1:28

Hi!

I have a datagrid with some custom DataGridComboBoxColumns. I have 3 columns that are supposed to be filled with different data according to what is chosen i the other comboboxes. It's kinda like this. 1st column is e.g. a list of box names. The 2nd column are item types inside a selected box. 3rd column contains names of the selected item type. If you have 2 items of type 'Car' in the box, the 3rd column will contain e.g. "Car 1", "Car 2".

I set the datasource for the comboboxes in a TableStyle. I need the data for each combobox to be updated dynamically and i need different values in the comboboxes for each row.

Is this even possible??

Thanks,
Atle

That's all the picture box does.

You can probably read the jpeg that you want and pass the stream into a constructor.

Substring.. How??

oneyard1-Aug-05 23:52

i have a very long text in one line... more than 1000 words...
my problem is...
i want to divide the whole line into a few lines...
a line can contain only 1033 character (including white space)...
and also... each line must have a header...
after dividing the line... then save it into a file...

my code doesnt work... Confused | :confused:

here is the method...

<br />
public void SaveCaptured(string savingFile,int count)<br />
		{<br />
			string fileName = countFileName.ToString() + ".rtf";<br />
<br />
			StreamWriter sx = File.CreateText(fileName);<br />
			DateTime myDate;<br />
			myDate = DateTime.Now;<br />
			string myTime = myDate.ToString("yyyyMMddHHmmff");<br />
			string lining;<br />
<br />
			int totalLine = count%1033;<br />
			MessageBox.Show("count%1033 = " + totalLine);<br />
<br />
			for(int i=1; i<=totalLine;i++)<br />
			{<br />
				<br />
				sx.Write("189000000000000000000023           000" + myTime + "000            01033                OBFT00xx x 30UG                                                                            ");<br />
				for(int j=0;j<1033;j++)<br />
				{		<br />
                                        lining = savingFile.Substring(j,1);	<br />
					sx.Write(lining);<br />
				}<br />
				sx.Write("\n");<br />
			}<br />
<br />
			sx.Flush();<br />
			sx.Close();<br />
<br />
			return;<br />
		}<br />

anybody can help me refining my code??

thanx in advance... Big Grin | :-D

% is the modulo operator. That means that totalLine will not at all contain the number of lines, but the number of characters on the last line.

As you don't remove the first 1033 characters from the string, you will be looping out the same characters time after time.

Try something more along this:

while (count > 1033) {<br />
sx.Write("189000000000000000000023 000" + myTime + "000 01033 OBFT00xx x 30UG ");<br />
sx.Write(savingFile.Substring(0,1033));<br />
savingFile = savingFile.Substring(1033);<br />
count -= 1033;<br />
}<br />
sx.Write("189000000000000000000023 000" + myTime + "000 01033 OBFT00xx x 30UG ");<br />
sx.Write(savingFile);

sx.Write("189000000000000000000023 000" + myTime + "000 01033 OBFT00xx x 30UG ");
sx.Write(savingFile.Substring(0,1033));
sx.Write("@ \n");
savingFile = savingFile.Substring(1033);
count -= 1033;
}
sx.Write("189000000000000000000023 000" + myTime + "000 01033 OBFT00xx x 30UG ");
sx.Write(savingFile);

just add one more line and it works...
but it save the characters directly...
i mean... it cut in the middle of a string...
eg: per //line 1
cent //line 2 <--continue from line 1...

issit posibble to make it recognize whether it is a whole string or not?? Confused | :confused:

Of course it is possible.

Use the LastIndexOf method to search for the first space before the last possible split point.

I use the same method here:

how to display/ show() form in a tab page?

2-Aug-05 2:17

You need to send the parts of the app individually, or create this shared class in a dll that both projects use, so their type is the same.

hi,

anyone noes how can i display/pop-up a form IN a tab page? instead of simply typing

form2 frm = new form2();
frm.Show();

wat codes do i write to tell the program to display the form at a certain place such as in a tabpage for my app?

thanks..

Christian Graus2-Aug-05 2:16

Why do you keep asking the same questions over and over ? Why would you want to do such a thing ?

The tab page has a controls collection, adding your form to that would be the only way, but it means the form needs to be written badly, if you want the tab page to have any access to it's properties.

It's a hack, I recommend against it. Just create tab pages, if that's what you want.

sorry, cos i was afraid nobody'll see n ans the older posts.. so i posted again.. also, i don get wat u mean sometimes cos im still tryin to grasp c# concepts.. i read articles n books but still hardly get it.. i really need hands on learning - exploring/learning c# in the process of doing this app.. i feel that i learn better n faster like this.. im v sorry that u've to tell me over n over again.. but im stressed... it's kinda rush as there a few parts to my app and i gt to make it neat n working in time.. so i really really do appreciate your effort..

i wan to let forms display in a window-like or panel-like format.. dat's y i chose to use tab page.. mayb that's not a wise choice but as long as i can get it workin n displayin the way i hope to, i wld like to move on wif my tasks already..

firstly, i wan to check wif u how to add my form to controls collection.. do i click on tab box > properties > controls collection? den frm there how do i add the form? i need some simple guidance here.. pls help me...

thanks a lot..

Perhaps you need to write some console stuff before you start trying to grasp how a GUI app works ? That's sure what I did when I learned C++, and I'm sure I'm all the better for it. Bite off a piece at a time, don't try to swallow it all at once.

nidhelp wrote:

It worries me how many people are asking questions that show a lack of basic knowledge, and at the same time talk about being worried for their deadlines. THere's nothing wrong with being a beginner, but why do you have a deadline ?

Dude, the deliberate bad spelling is just annoying.

That was a guess, I just tried it and it doesn't work. You CANNOT add a form to a tab page. You need to recreate the form in a tab page, you can just copy and paste in the designer to do this. The form class is useless to you if you want it to show in a tab page.
