If you're trying to interact between two already loaded instances of different user controls I would possibly use an event. For example, when u2 button is clicked raise an event to the calling page, the calling page can then call the method in u2 as it already knows about it.
Alternatively, you can create a property on u2 of type u1 and the consuming page could set the property on u2 to the instance of u1 on the page, u2 will then have access to u1 and its methods.

I have table like that:
wel here is Event
void grid_RowCreated(object sender, GridViewRowEventArgs e) {
if (e.Row.DataItem == null) {
return;
}
LinkButton cmdCity = (LinkButton)e.Row.FindControl("cmdCity");
if (cmdCity != null) {
int id = (int)grid.DataKeys[e.Row.RowIndex].Value;
cmdCity.CommandArgument = id.ToString();
}
}
and this event retrieves from data only one field concrete ID
I want to retriwe another ID's to like countryid, regionid or etc.
How do that??

It isn't very clear to me what you are asking?

The obvious way is to create a string datakey which is an amalgamation of ids. There's only one data key value, so it needs to contain the values you want, or give you what you need to look them up

I have not written whole code but
when This Event will rise, corresponding row from data binds to e.Row.DataItem
and this line
int id = (int)grid.DataKeys[e.Row.RowIndex].Value;
retrieves only one field from data and it's PK ID.
I want to retrieve aother values too.
there is grid.DataKeys[e.Row.RowIndex].Values too, but i didn't understand ho do it.

Hello Everyone,
I want some of my website pages secure (SSL enabled) because I need to transmit sensitive information.
I read some of the articles on WEB, but none of them seems to give me accurate and step by step instructions on doing it.
Please help me out regarding this.
Thank you.

For this you need a certificate that must be installed on IIS.Even you generate the certificate request from IIS also and get the certificate from.For detail step see the Link

I have created a very powerful web-based software as part of my thesis. Though, nobody helped me in my project, yet I have to submit my software with full source code. Some of the features of my software are unique & even not available in SAS or SPSS. However, some of the scientists at my Instt. will publish & commercialize it without mentioning my name anywhere and all my effort will so far, would become futile.
Is there, any way that I can make the source code uneditable or encrypted, so that nobody can edit it except me. Or is there any way that I put my name in the source code such that nobody will be able to remove afterwards.
Please help

I beleive you have developed your project is layer architecture manner like BLL, DAL and UI . and for BLL and DAL you haev your own dlls. So try to obsfucate the dll using some tool and Before giving the site, give the published version of your site, DO NOT give the website by just as copy paste. Give the Published Version.
And have a look around the google, you will also find some alternative solution.

By the way navaneeth, Here is my latest one. Have a look

One thing you can,you can obfuscate the code,so that nobody will be able to understand.For this you can use visual studio obsfucator.You can also find list of obsfucator here

If they can read it to mark it, they can copy it. Therefore, you have no options. I believe most schools basically assume they own your code. Is it really that great ? I mean, should you consider leaving to commercialise it ?

I've never tried this with a Web application, but you can create native images of your .NET libraries using NGen.exe[^]. As long as their processor is the same as yours, the DLLs/EXEs will run. Again, don't know how well that works in a Web-based application. YMMV.

I have a web form with a table control. No. of columns & no. of rows are asked by user and table is generated with cells filled with textboxes dynamically. The id of textboxes are generated dynamically. User enters the values in textboxes in table & click calculate button, on which I want to supply a set of results based on input data. Can anybody tell me how to fetch the value entered in a textbox at runtime. I am using following code.
public void CreateTableRawData(int rows)
{
for (int i = 0; i < rows; i++)
{
TableRow tr = new TableRow();
TableCell td = new TableCell();
TextBox txt = new TextBox();
td.Controls.Add(txt);
txt.ID = "txt" + i.ToString();
tr.Cells.Add(td);
Table1.Rows.Add(tr);
Table1.Caption = "Raw Data Form";
}
}
protected void Button2_Click(object sender, EventArgs e)
{
int rows = Convert.ToInt32(TextBox_rows.Text.ToString());
double[] data = new double[rows];
string [] dataText = new string[rows];
Table tbl = (Table)Panel1.FindControl("Table1");
for (int i = 0; i < rows; i++)
{
data[i] = Convert.ToDouble(Table1.Rows[i].Cells[0].Text.ToString());
}
data[0] = Convert.ToDouble(Table1.Rows[0].Cells[0].ToString());
Label lbl = new Label();
double sum = DistributionFitting.Statistics.Sum(data);
lbl.Text = sum.ToString();
}
I am getting following error at runtime.
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index

As exception shows,you must be accessing some array's index that doesn't hold.Debug it ,you'll be able to get the problem

Try to debug your application and check which line is throwing the exception. check the index of the array.
One more important thing, you are creating the textboxes runtime. You need to create the textbox before Page_load(). Because in ASP.NET Page life cycle, ViewState Data and PostBack data loads just before the Pageload. So if you create any control after page load you can't restore the postback and view state data.
The best option, try to create your controls in Page_PreInit() Event.
