Hello,
I am working on a school result processing project. I have one checkedlist control which have 3 options:(To choose paper code)
All
First
Second
to select the paper code option. All stands for all papers i.e. paper1 and paper2; while if any of other than "All" option checked by user; the respective action should be taken place. Suppose, user checked on option First, then all records whose papercode <> 1; will be deleted by command.ExecuteNonQuery() and if user checked on Second, then all records whose papercode <> 2; will be deleted by command.ExecuteNonQuery(). If user checked on All or any of First/Second; no action is needed; because All option means no action required.
Kindly help to code this requirement or let me know, if i am not clear to explain my question.
Thank and Regards
Girish Sharma

Your problem is not very clear.Can you explain a bit?
What I understand, you need to delete the record if user selects first or second and dont need to do anything if user selects all. if yes then have check at serverside and take the action accordingly.

Hi Brij,
Thanks for your reply and time given to my problem. Let me once again clear it more:
If user selected "All" option with/without First/Second option then no action is required.
If user selected First only then
deleted those records whose papercode <> 1
Endif
If user selected Second only then
deleted those records whose papercode <> 2
Endif
If user selected First and Second
No Action required
Endif
If user selected All+First+Second
No action required
Endif
Means, only action required on selection of single "First" or "Second" option and wish to perfrom some delete operation on table.
Its vb.net 2005 project please.
Regards
Girish Sharma

hi, iam using asp.net2.0 with c#
in my gridview 1st column is checkbox control in template fileds
and iam using paging also. when user clicks the button ,all selected no of check boxes data has to be send in mail
can you give example which helps me
|
|
|
|
|
So what problem you are facing,on button click, iterate throgh the gridview rows and check the checkbox status and accordingly send the mail to all checked.
if facing any problem in sending mail then have a look
|
|
|
|
|
while iterating how i have to take that data and print as it is
can you give example which helps me
|
|
|
|
|
See, you need to prepare the format of mail as you already have all the data or you can read all the data from grid.So create mail body accordinly and send mail. and if you want the same html as grid then you can get the html as
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
HtmlTextWriter textWriter = new HtmlTextWriter(sw);
grid1.RenderControl(textWriter);
string gridHTML= sb.ToString();
Now you have the html of grid as gridHTML and now use as you need.

hello all,
I have made a project in asp.net, in which there is need to have countDown timer using javascript .So, I have made a code for it. But it resets after very postback or you can say on every page refresh, Timer reset .
There must be static timer that should display some minutes and secs to remain .
Could anyone know the code of reverse timer for minutes and seconds that should not reset after page refresh.???
Thanks in advance
|
|

|
|
You must save the timer count on postback
and restore timer count when page reloads,
Use hidden field or cookie or the query
string to store the timer count value.
|
|
|
|
|
When the page loads, it checks for a particular cookie. If it is not found, it is the first time the page has been loaded: figure out the time to which you are counting down and set the cookie. If it is found, load it and start counting down again.
An alternative would be to store the time server-side -- the session object might be a good choice. If Session("Deadline") does not exist, the page is being generated for the first time; if it does, it contains the time. Use it to set a hidden field in the code that your Javascript will reference.
There are problems with either approach, but they should usually work.

hi, iam using asp.net2.0 with c#,
in my textbox property textmode=multiline, so user can enter 4to 5 email ids
iam validating this textbox through regular expresiion validator but it is giving error message, so how to check for 4 to 5 email ids in textbox
can you give me example which helps me.
|
|
|
|
|
if there are multiple mailids and you donno the actual count then another way, go for custom validator and in the jas function you can validate each mail id using regex.
|
|
|
|

For Help please click on below link,

|
|
|
|
|
If every address is on its own line, you can use the textbox's Lines property, like so:
For Each Line As String In TextBox1.Lines
If Not IsValidEmail(Line) Then
...
End If
Next

I have image control on my asp.dot page, i want to print that image. how can i do it? help please
|

You know 'window.print()' function will print the HTML content of the current page in the browser window.
Put the image in a DIV tag and then use the following code. The content of the DIV is written to a new window and then printed in this code.,
<script type="text/javascript">
function ClientSidePrint(idDiv)
{
var w = 600;
var h = 400;
var l = (window.screen.availWidth - w)/2;
var t = (window.screen.availHeight - h)/2; var sOption="toolbar=no,location=no,directories=no,menubar=no,
scrollbars=yes,width=" + w + ",height=" + h + ",left=" + l + ",top="+t;
var sDivText = window.document.getElementById(idDiv).innerHTML;
var objWindow = window.open("", "Print", sOption);
objWindow.document.write(sDivText);
objWindow.document.close();
objWindow.print();
objWindow.close(); }
</script>

Store all "checked item" before you are rebinding the data for next page. Use a javascript function to get those "checked item"'s id and store in hidden field. In the new page you get this hidden fieldds id value to know which have been checked.

Hi,
you could also subscribe to the CheckedChanged event of your checkbox and save some identifying
information to ViewState for Checkboxes with chkXY.Checked = true.
Use the index of the row or whatever if you dont have a identifying key for that row.
That means:
- Use CheckedChanged event of your checkbox (which is inside a column template)
- if checked = true, add it to a (your) collection saved in ViewState
- if checked = false, remove it from a (your) collection saved in ViewState
- On "Do-My-Saving-To-DB-Stuff-Button-Click":
Iterate through your "selectedItemsCollection" which is saved in ViewState and add the records
