Checkbox Problem

[JIM]

Hello,

I would like to solve the following problem :

I've a web site with ex. 5 checkboxes
Each checkbox contains the name of a certain task
ex.
asp:Checkbox 1: Task 1
asp:Checkbox 2: Task 2
...
asp:Checkbox 5: Task 5

Each time a task is finished on the server I would like to
inform the user that the task is finished by checking the checkbox to true
(Checked = True)
But I only see those checkboxes checked when the last tast is finished
(Then I see all 5 checkboxes checked)

How can I force my website to show each checkbox checked when a task
is finished ?

I'am using asp.net with Visual Studio 2003

Many thanks !

It depends on how you are using the code..
usually if I am trying to do something like this, I dont think there will a
problem..
what I will do in the most simplest way, is to chek the box and make a
postback, and its done!
Maybe you can tell us a bit more about how YOU are trying to achieve this by
posting some code or putting ur concept down here...
Hth...

I have a system that lets admin users select from a list of reports what
certain users can see. They do this by ticking checkboxes, this then enters
permissions into a database table. My problem now is that I need to let admin
edit the permissions. I'm a little stuck how to go about doing this so any
help would be great. Here is my code DB etc. <!--- Reports Table, this
produces a list and the admin can tick if they want a user to see the report
---> <CFquery name='Get_dirs' datasource='tns'> Select * from directories_tbl
Where Parent_id = 2 </CFquery> <!--- We then output this so the admin can pick
what user has access to what report ---> <cfoutput> <input type='hidden'
name='user_id' value='#url.user_id#'></cfoutput> <cfoutput query='get_dirs'>
<tr> <td width='20'><input type='checkbox' name='dir_id' value='#dir_id#'></td>
<td> <div align='left'>&amp;nbsp;#ucase(DIR_NAME)#</div></td> </tr></cfoutput>
This then gets inserted into the permissions table, this all works fine, the
problem is when I want to edit. <cfloop index='i' from='1'
to='#ListLen(form.dir_id)#'> <!--- Now insert each permission into the database
for the user. ---> <cfquery datasource='TNS'> INSERT INTO
static_perm_tbl(user_id, parent_id) VALUES (#form.user_id#,
#ListGetAt(form.dir_id, i)# ) </cfquery> </cfloop> So now I want to output
the first query and populate it with the results from the static_perm_tbl . . .
.. any ideas? Regards Craig

Hi everyone,

How to loop through the checkbox which is inside a datagrid?

Thanks,
May

What are you looking to do? Just a though. I use a class for the lineItem (
that I write with an member variable for each column ) and a list of those for
the dataprovider. That way I can dig through the data without dealing with the
datagrid at all. It also make moving the data around easier. Instead of reading
out each line into something else, you just send the list of lineItems.

Hi,

Thanks for your reply. What I want to do is shown below. And the datagrid is
shown below:

|---------|----------------|----------------|
| id | Checkbox | TextInput |
|---------|----------------|----------------|
| 1 | false | |
| 2 | true | Create |
| 3 | true | Update |
|---------|---------------|----------------|

What I want to do is loop through the checkbox which is inside a datagrid. If
it is true, then get the id value and TextInput value out from the datagrid.
And then update the database.

Thanks,
May

Hi,

One solution to your problem could be:
- Create a class "myItem" representing one line of information with 3
attributes: id (int), checked(boolean) and textValue(String)
- Create an arrayCollection which will be the dataprovider of your datagrid.
This arrayCollection will contains object of type "myItem".
- In the item renderer of the column with the checkbox, on the CheckBox
object add a change listener like this id="chkbox" change="(this.data as
myItem).checked = chkbox.selected"

When you want to check if there is something checked, you don't use the
datagrid anymore but simply go through the arrayCollection you gave as a
dataprovider.

Hope it's clear.

Hi David,

Thanks for your help! I am new to Flex. If possible, please give me sample
code. Thanks again!

Hi,

I did the following quick and didn't test it but I guess it should work.

Good luck,
David


// FIle MyItem.as
package
{
public class MyItem
{
public var itemId:int;
public var checked:Boolean;
public var textValue:String;

public function MyItem()
{
}


}
}

//Your main application .mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
xmlns:local="*">

<mx:Script>
<![CDATA[
import mx.controls.Alert;
private function displayChecked():void {
var res:String = "";
for each ( var item:MyItem in myDataProvider) {
if ( item.checked ) {
res += item.itemId + " " +item.textValue + "\n";
}
}
Alert.show(res);
}
]]>
</mx:Script>

<mx:ArrayCollection id="myDataProvider">
<local:MyItem itemId="1" checked="false" textValue="text value 1" />
<local:MyItem itemId="2" checked="false" textValue="text value 2" />
<local:MyItem itemId="3" checked="false" textValue="text value 3" />
<local:MyItem itemId="4" checked="false" textValue="text value 4" />
<local:MyItem itemId="5" checked="false" textValue="text value 5" />
</mx:ArrayCollection>

<mx:VBox width="100%" height="100%" horizontalAlign="center"
verticalAlign="middle">

That's great. Thanks a lot David. I will try your code later.
