Hello there,
I've created UserControl which is used as a menu. It is populated dynamically and has two levels.
The weird thing is though that second level controls' click event is fired but it the code executed in it seems to have no effect at all:
public void SubCourseRoundMenuClick(object a, CommandEventArgs e)
{
pnlCourseEvents.Visible = false;
pnlCourseSubEvents.Style["display"] = "block";
}
Both properties changes to their old values when observed in any event fired after SubCourseRoundMenuClick.
All menu items and subitems are populated at the same order on every postback. EnableViewState=false on UserControl (though i've tried other way round as well).
For suspect ViewState is playing tricks on me.
This issue is really driving me bonkers so any advice or guidance would be much appreciated.
Best Regards,
Dave

Do you modify these values in page_prerender, which fires afterwards ?
I am not sure how viewstate factors into it. Or are you saying that the control resets to it's default state on the next postback ? Perhaps you need to store something in the viewstate to tell you the state of this control ?

Hi Christian,
What I'm saying is that anything I change in click event handler of UserControl doesn't seem to work. I've even tried adding private variable
private int test; . I've changed it in click event handler and it's back to 0 in any event fired afterwards. Bear in mind that it's the same postback!!!. And that is very very weird 
Regards,
Dave

what is the purpose of repeater control in asp.net
|
|
|
|
|
|
The Repeater control displays data items in a repeating list. Similar to DataList, the content and layout of list items in Repeater is defined using templates.
Unlike DataList, Repeater has no built-in layout or styles.You must explicitly declare all HTML layout, formatting, and style tags within the templates of the control.
i hope below link will give enough info

Is it not, to some extent at least, implicit what a repeater control would do?

Here I give you sample code.
This helps you.
Bitmap b = new Bitmap(500, 100);
Graphics g = Graphics.FromImage((System.Drawing.Image)b);
//g.FillRegion(Brushes.Red,
string message = "This is the string to highlight a word in.";
// Declare the word to highlight.
string searchWord = "string";
// Create a CharacterRange array with the searchWord
// location and length.
CharacterRange[] ranges =
new CharacterRange[]{new CharacterRange
(message.IndexOf(searchWord), searchWord.Length)};
// Construct a StringFormat object.
StringFormat stringFormat1 = new StringFormat();
// Set the ranges on the StringFormat object.
stringFormat1.SetMeasurableCharacterRanges(ranges);
// Declare the font to write the message in.
Font largeFont = new Font(FontFamily.GenericSansSerif, 16.0F,
GraphicsUnit.Pixel);
// Construct a new Rectangle.
Rectangle displayRectangle = new Rectangle(20, 20, 200, 100);
// Convert the Rectangle to a RectangleF.
RectangleF displayRectangleF = (RectangleF)displayRectangle;
// Get the Region to highlight by calling the
// MeasureCharacterRanges method.
Region[] charRegion = g.MeasureCharacterRanges(message,
largeFont, displayRectangleF, stringFormat1);
// Draw the message string on the form.
g.DrawString(message, largeFont, Brushes.Blue,
displayRectangleF);
// Fill in the region using a semi-transparent color.
g.FillRegion(new SolidBrush(Color.FromArgb(50, Color.Fuchsia)),
charRegion[0]);
b.Save(Server.MapPath("MyImage.png"), System.Drawing.Imaging.ImageFormat.Png);

I'm not sure what the other guy was saying, but you need an OCR library to find text in an image. Then you need to work out where that text is ( which is a different thing ) so you can highlight it. A far from trivial task.

Hi,
I want that my query automatically runs in google and the output list of all the sites on first page get added to my sql database.
i am able to run my query get the output but dont know how to pull it into database.

Hi,
how does the output from google look? Do you have the concrete URL's or the content of the search results?
Somewhere in the code is the point where you have the result of the google query. There you have to implement a database access: Open the connection, building an insert command, executing the command and last but not least closing the connection.

Hi,
Actually i got data entered into a text box.
Send that data to google using a hyperlink to google.
In that fashion i got the second page from google ,its the normal search page you got when u submit ur query in google .

Hi,
I think you have to get the google page by sending an HTTP-Request programmatically. Then you are able to retrieve the response within your code. There you could extract all URLs and store them into a database.

Hi,
it is easy to get the client IP-Address with
<br />
Request.ServerVariables["REMOTE_ADDR"]<br />
If the client pc is a part of your intranet than you could try to use DNS to resolve the computer name from the IP. If this is not the case, you could try to accomplish this by using JavaScript, to get the name on the client side and then send this information to your server.
Hope this helps.

Sebastian

I don't think so that you will able to retreive computer name. YoU will just get the IP Address.

Well that's what I said.

try this one...
Dim strcomputername As String
Dim host As System.Net.IPHostEntry
host = System.Net.Dns.GetHostEntry(Request.ServerVariables.Item("REMOTE_HOST"))
strcomputername = host.HostName

You must be the stupidest person on the internet. You have been asked over and over how to get client information from a server. You have been told over and over that this is not possible. Why do you keep asking ?

Hello,
okay, let's first try to sort. You are building a reservation website, am I right? And you want to show if a room is full or not?
So what are the missing functions? What do you want to know exactly? I didn't get the question.
Regards
Sebastian

Sorry, either this is a college assignment, in which case if you cannot do it go back to your tutor, or you are being paid to do it, in which case don't lie about your abilities.
