Good.
Check the line
Processor.Data.WebsitePageDownload.AcceptChanges() Set the cursor on the AcceptChanges method, hit F12. Set breakpoints there, and make sure that the method does not swallow the changes.

not sure what you mean swallow, but the data is updated but there seems to be a problem when it returns to the UI

I'm expecting a try-catch in that method that hides the exception that is thrown.
Rhyde Marsh wrote: the data is updated but there seems to be a problem when it returns to the UI
Is the data updated beyond the 350-char mark? How do you know there's a problem? Do you have an exception and a stack-trace?

yes it updates but then i get a nullrefference exception. so before the 350 mark it updates and refresh fine but anything after that i get the error

I assumed that was fixed, based on your previous post.
Can you post the entire stacktrace from the exception?

That could be tested easily by giving the columns a fixed width

yes, but cannot be limited because the length of the url entered is unknown

This is not helping much, we're talking about different things.
If you can fix the size of the column in the grid in where it is displayed to 100 pixels, then you can still enter long strings. It would prove whether or not the observed behaviour is caused by the internal resizing, or somewhere else.
If fixing the width helps, then you'll need to look for other alternatives or find a fix. If fixing the width does not help, then the error is occurring somewhere else.

Hi everybody!
I hope I am posting this question on the correct forum but anyway, I'm having some difficulty getting a Legend on a Chart Control to behave in the way I would like it to.
I want the legend to be placed under the chart, and legend items for each series to be added to the legend in the order the series are added to the chart.
Say I have 6 series which are added to the chart in order: A, B, C, D, E, F.
Suppose that the chart area in which the legend is docked is such a size that the legend has 3 columns.
I want the legend to be filled like so:
A B C
D E F
i.e. columns first, then rows.
Frustratingly, this is not the behaviour I am getting.
As I add the first three series all is fine, and I get a legend with 3 columns and 1 row filled like so:
A B C
But when I add a 4th series, instead of getting:
A B C
D
as one might expect, the legend looks like this:
A C D
B
Then when I add the next series I get:
A C E
B D
And when I add the final series I get:
A C E
B D F
This is really frustrating me as I have trawled the internet and cannot find any mention of this issue, let alone an answer. Surely wanting the legend to be filled columns first, then rows, would be the most logical way of doing it, so I can't believe that the .NET guys haven't allowed for this possibility.
Anyway, my legend is set with the following properties:
Legend legend = new Legend("Legend1");
legend.LegendItemOrder = LegendItemOrder.ReversedSeriesOrder;
legend.Alignment = StringAlignment.Center;
legend.Docking = Docking.Bottom;
legend.LegendStyle = LegendStyle.Table;
legend.TableStyle = LegendTableStyle.Wide;
legend.IsEquallySpacedItems = true;
legend.AutoFitMinFontSize = 6;
legend.IsTextAutoFit = true;
chart.Legends.Add(legend);
Can anyone please help me?
Thanks, Nick

I'm sure you have searched plenty
http://stackoverflow.com/questions/1917798/ms-chart-control-change-the-order-of-series-in-a-legend[^]
I don't know the complexity of your chart, but I do know that the order in which you load the series to the chart is important, and what type of chart you select as well such as a series chart with plot lines.
I guess take a pie chart, now you have a legend to explain the pieces of the pie, there really is no order to it. Unless the largest pieces of the pie down to the smallest are the order.
I've always had to experiment for hours to get them right, and after 100's of them, narrow down which charts to stay away from.
I'm not sure if you can do multiple legends, and display them in rows or columns.
Not the answer you want, but your going have to take to pencil and paper and record your results based on what you get, or try the Microsoft Forum for Chart Control at asp.net

Hi all,
I am very new to windows form and facing a problem with infragistics numeric editor. I need to allow user to input the value max "100.00%" or below (like 45.78, 99.00, 99.99). I am setting following propety for this:
MaskDisplayMode =IncludeBoth
MastInput= {LOC}nn.nn%
MaxValue= 100
MinValue = 0
It allows user to input 100.99% but i need to restrict so that user cann't input more than 100.00
Help really appreciated.
Thanks,
Sri

Ask the infragistics support team. It's not a generic control, not part of the framework.
srinandan.. wrote: It allows user to input 100.99%
Sounds like a bug where one only checks the integer-part for the max, not the decimal.
You could easily do this without infragistics; there's quite some material out there on "validation".

New to VS C# and inherited a partially developed C# Winform project. Need some guidance.
Windows Form displays SQL results in a tree view with the intent of the user selecting item(s) from the list. You have to scroll the list and find item(s) you want to select.
Items have a # and a name and most users know one or the other.
Question: Is there a way to include a text box or something that would move the tree display to characters typed in the box? If yes how is it done in VS C#?
Anyone have a sample project I could download? Doesn't have to be SQL data, could be a windows directory or something.

Thanks but very few Winform samples in C# and none related to my question.

Are you saying you don't know how to handle text input, and use the content to change the focus of your TreeView?

As a newbie I'm not sure what your response means. I want the display to scroll based on user input in a textbox rather than using the scrollbar and mouse. If that's what you mean by your response, than yes, I don't know how.

I am still not sure what you are getting at. A textbox is used for text input, and your program can capture that text as it is entered or when it is complete. It then makes use of that text in whatever way necessary. Scrolling of a view is a separate issue and would require some code to be written to move a certain tree item to the top of the form (or area of the form). The suggestion at http://stackoverflow.com/questions/457932/c-sharp-how-do-i-scroll-selected-treeview-node-into-view[^] should help you to figure out how to ensure the selected node is visible.

Quote: Hi Hawk73ku,
According to your description, you'd like to find the specified treenode from the TreeView.
I wrote a sample for you, Here are my steps.
Step1: create a form with a textbox, a button and a treeview.
Step2: set the button click event handler like this.
List<treenode> tnlist = new List<treenode>();//collect the result nodes
int count = -1;//used to record the index of the selectnode
private void button1_Click(object sender, EventArgs e)
{
this.treeView1.Focus();
tnlist.Clear();
this.getallTreeNode(this.treeView1.Nodes, tnlist);
if (tnlist != null && tnlist.Count > 0)
{
count++;
if (count >= tnlist.Count)
{
count = 0;
}
this.treeView1.SelectedNode = tnlist[count];
}
}
private void getallTreeNode(TreeNodeCollection nodes, List<treenode> ltn)
{
foreach (TreeNode tn in nodes)
{
if (tn.Text.ToLower().Contains(this.textBox1.Text.ToLower()))
{
ltn.Add(tn);
}
if (tn.Nodes.Count > 0)
getallTreeNode(tn.Nodes, ltn);
}
}
the getallTreeNode method in my code is used to collect the result treenodes to a list.
Results:
#TreeNode Class

If you have any other concern regarding this issue, please feel free to let me know.
Best regards,

Unfortunately you did not make it clear that you did not know the fundamentals of writing a WinForms application. Had you done so you would have received somewhat different responses. Although these forums are designed to help people with specific questions (see http://www.codeproject.com/Messages/3137519/Forum-Guidelines-PLEASE-READ.aspx[^]), rather than teach them how to program. If you want to learn from the beginning then there are many websites that offer beginners' tutorials, including here at CodeProject; but you are expected to go and find them for yourself.

Pardon me. Had I known English wasn't understood here I would have made it painstakingly clear but thought my first sentence, "Quote: New to VS C# and inherited a partially developed C# Winform project. Need some guidance.
said it all. Also I didn't see anywhere that you don't take kindly to folks learning. I'll make a note of that. But if my opening statement didn't work for you I would have thought an intelligent being such as yourself would have surmised my skill level based on the question. (go figure)
It's very presumptuous of you to think I haven't gone through numerous tutorials and articles on the topic and while I've learned how to build the tree from a SQL source and update it, I did not find anything addressing my question and is why I came here hoping for some guidance. I'm so sorry I did that. I'll think twice about asking another.
Have a good day.

I presumed nothing, but I can only base my responses on the information you provide. If it's not clear then I ask for clarification, which I did in several responses. If you can't understand my questions then you can do the same. I'm sorry that I could not provide all the information you wanted, but I did (I thought) make it clear on my part that I did not fully understand what you were asking for. And I'm sorry that you seem to think that you are not getting the value for money that is your due, but we do this in our own time and at no cost to you.

And no, there's very little chance that anyone has done "exactly" what you need, so you search for an example that comes close and start there. Start here[^]
