Hi, I am creating a 5 star rating control using callbacks.
I am not able to send the value to the parent page and then save it. When I try to capture the click event of the image, I guess multiple events occur and then I loose the actual value. The actual value does not persists.
I have used five image controls and One hiddenField named 'hdn' and have written javascript functions for handling the OnMouseOver, OnMouseOut and Click Event. The functions are s follows:
--------Image Click Event----------
function onImgClick(strVal)
{
var countRec;
var imgName;
var message = strVal + ":" + "Click";
var context = "Click";
CallServer(message, context);
}
------------------------------------
----------OnMouseOver--------------
function callSwapImage(strVal)
{
var countRec;
var imgName;
for (countRec = 1; countRec<=parseInt(strVal); countRec++)
{
imgName = "imgStar" + String(countRec);
document.images[imgName].src = "images/starGold.gif";
}
}
---------OnMouseOut------------
function callSwapRedo()
{
var message = document.getElementById("rc1_hdn").value + ":" + "Redo";
var context = "Redo";
CallServer(message, context);
}
-------------------------------
In the code behind file of the user control I have written the following code in the Page_Load Event
protected void Page_Load(object sender, EventArgs e)
{
sCallBackFunctionInvocation = Page.ClientScript.GetCallbackEventReference(this, "message", "ShowSuccess",
"context");
String callbackScript;
callbackScript = "function CallServer(message, context)" +
"{ " + sCallBackFunctionInvocation + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
"CallServer", callbackScript, true);
HiddenField hdn = new HiddenField();
}
For the RaiseCallbackEvent I have written
public void RaiseCallbackEvent(string eventArgument)
{
string[] remCount = new string[2];
if (Rated != null)
{
if (eventArgument != "")
{
remCount = eventArgument.Split(':');
if (remCount[1] == "Click")
{
EventArgs args = new EventArgs();
Rated(this, args);
}
}
if (hdn.Value.ToString() == "" && remCount[0] == "0")
{
returnValue = "0";
totChecked = returnValue;
hdn.Value = returnValue;
}
else
{
returnValue = remCount[0];
hdn.Value = returnValue;
totChecked = returnValue;
}
}
RateVal = returnValue;
}
The below function is written to send the result back to the client end
public string GetCallbackResult()
{
return returnValue;
}
-----------------------------------
My problem comes now that I want to send the value for the image clicked to the parent page so that I can save the rating. For this I have declared the following event before the page load
public event System.EventHandler Rated;
and then I have declared the event handler for the same in my parent page
protected void Page_Load(object sender, EventArgs e)
{
rc1.Rated += new EventHandler(rc_fetchData);
//rc.Rated += new CommandEventHandler(rc_fetchData);
}
private void rc_fetchData(object sender, EventArgs e)
{
lblMsg.Text = ((HiddenField)rc1.FindControl("hdn")).Value.ToString();
//((HiddenField)rc.FindControl("hdn")).Value.ToString();
}

How can i use two filters in the following code
person pp = obj.Find(delegate(person p) { return p.name == "abc"; });
because there should be one return statement in a single block.
So how will i declare another filter to refine the record
Yesterday is a canceled check. Tomorrow is a promissory note. Today is the ready cash. USE IT.

Sonia - you asked this question below. Don't repost questions, continue threads instead as this is just plain rude.

You can write several statements and use logical operators to return the value according to your filter requirements.
Logical Operators in C#[^]

|
|

person pp = obj.Find(delegate(person p) { return p.name == "abc" && BUY_A_BLOODY_C#_BOOK_FOR_THE_HUNDREDTH_TIME; });

Possibly a little too subtle. I still don't think she'll get it.

Yes, I agree. I still have a lot to learn to achieve your level of sarcasm and wit

public partial class UserControl1 : UserControl
{
public object DataSource
{
get
{
return dgvSearch.DataSource;
}
set
{
dgvSearch.DataSource = value;
}
}
public string DataMember

get{ return dgvSearch.DataMember ;}
set { dgvSearch.DataMember = value; }
}
public UserControl1()
{
InitializeComponent() ;
}
and from parent form i am setting the datasources for my parent control
BindingSource datasource;
DataSet data=new C21_SecurityDataSet() ;
DataTable dt = data.Tables.Add();

Why not add order by [column name] ASC
Thanks

You could, but only with some extremely fancy logic. It's a string, so you have to abide by the rules of strings. Off the top of my head, I would think that you would have to remove the numeric type strings and sort them independently of the non-numeric strings and then combine the two together.

i can use the union query to first select the numeric and then an another union query to sort alphanumeric.
Am i doing right?

For the love of God Sonia, just try it. I'm not going to type your code out for you.

Convert the data type of the column on the fly using convert or cast then reorder the converted column using ORDER BY.
Make sure the converted type is integer!

Hi,
I don't think SQL offers the required ordering.
The "natural sort order" as used for file names by Windows Explorer is available through
P/Invoke, so you can implement an IComparer interface like this:
using System.Runtime.InteropServices;
public static int Compare(string s1, string s2) {
if (s1!=null && s2!=null) return StrCmpLogicalW(s1, s2);
else return string.Compare(s1, s2, true);
}
[DllImport("shlwapi.dll", CharSet=CharSet.Unicode, ExactSpelling=true)]
private static extern int StrCmpLogicalW(string s1, string s2);
I do not know how you could apply the above to database-based data; I would guess
you need to first fill a DataTable, then somehow get that sorted using the IComparer object.

Ordinarily I'd say left pad the numerics with SPACEs then sort, but SQL Server doesn't appear to have a PAD function?  I thought Oracle did. What Database system are you using?
Some ideas for SQL Server:
select * from PadTest order by
REPLICATE(' ',8-LEN(X))+X
or
select * from PadTest order by
case ISNUMERIC(X)
when 1 then REPLICATE(' ',8-LEN(X))+X
else X end

Hi,
I have a windows form with Ten Textboxes and I want to set text with Zero "0" using foreach loop.
Kindly tell me the method.
Thank you in advance

You can iterate through the controls on your form using Controls property and check whether the current control is textbox or not. If yes, set it's text to 0.

Hi,
I have to secure the HTTP communication between a client and a server which are placed on separate machines. Both client(C# appl.) and server(Java appl.) are desktop applications. I know that I have to create SSL on HTTP in order to obtain a communication over HTTPS. I don't know how to create the certificates and how to handle them. If you have any suggestions/links, write them here, please!
Thank you,
L.P.

The SSL certificate depends on what web server you are running. Try to Google "how to create https certificate" and you'll probably find an answer.

You can't!
Write to event log...

Thanks for the reply ..
but how does the general pop up ex: system connection, scan and etc pop up comes.
I think these are all services running in the system which on detecting the required thing generates an alert.
Isn't it???
Thanks

It can be done in round round way..
1) Create another application ie form application and create a property that will be displayed as the message.
2) When you require to show the message create the object of this Form and set the property to the message you want and call the Show() Method.
3) Now go to your service right click > Properties > In the first tab you will find some check box called "Allow the service to interact with desktop") and restart the service.
Note : It is highly discouraged to set the option "Allow the service to interact with desktop".
Thanks
