Hi,

I am facing the following problem :
In the <mobile:selectionList> control though
I have specified the items as -
<mobile:SelectionList runat="server" >
<item text="abc" value="abc"/>
<item text="efg" value="efg"/>
</mobile:SelectionList>
When I try to access it in code behind page
the selected item's Value gives me '0' for
item abc, '1' for item efg ..and so on ...
Is there any way by which I can access the values
I have supplied in the code.

Thanks & regards,
Mayur

Mayur,

Please post the relevant code that you are using to access the list value.. Looks like you are getting the index and not the value.

Anil

Hi,
Sorry for the delay in sending the code ...
The code is as follows :
// add the list items from the enumerator
while(keys.MoveNext() && values.MoveNext())
{
selaccessories.Items.Add(new
MobileListItem((String)keys.Current,(String)values.Current));
}

for retrieving, using the following code --

String strValue =
selaccessories.Items[selaccessories.SelectedIndex].Value;
String strText =
selaccessories.Items[selaccessories.SelectedIndex].Text;

so here in strValue it gives me the index as you said
and not the value passed in the while loop ...

Thanx,
Mayur

Mayur,

I tried a similar chunk of code (see below), and it seems to work as
expected.

Have you verified that the enumerator you are originally using is
returning the correct values, rather than just indices? One way you can
check this is to also bind the text to the value, i.e. change the
constructor to=20

new MobileListItem((String)values.Current, (String)values.Current)

and see what you get.

Thanks,
Shanku

Here's the code I tried. When you run this, the label gets set to "Value
0".

<script runat=3D"server">

void Page_Load(Object sender, EventArgs e) {

for (int i =3D 0; i < 5; i++) {
theSel.Items.Add(new MobileListItem("Item " + i, "Value " + i));
}

theLabel.Text =3D theSel.Items[0].Value;

}

</script>

<mobile:Form runat=3D"server">

<mobile:Label runat=3D"server" id=3D"theLabel" />
<mobile:SelectionList runat=3D"server" id=3D"theSel" />

</mobile:Form>
=20
=20

=20

=20

=20

Hi Shanku,

I tried adding MobileListItem with hardcoded values
instead of using the values from enumerator as
follows :
theSel.Items.Add(new
MobileListItem("Item1","Value1");
theSel.Items.Add(new
MobileListItem("Item2","Value2");

The HTML output is -
<select name="theSel">
<option value="0">Item1
<option value="1">Item2
</select>

and the WML output is -

<select iname="theSel">
<option>Item1</option>
<option>Item2</option>
</select>

So What may be the problem ?
Is it because I am using .NET Framework v1.0.2914
and MMIT v1.0.1722 ?

Thanks and Regards,
Mayur

Did you check theSel.Selection.Value on postback after selecting a list
item, or are you concerned about the value attribute in the markup?

The value attribute output on the client will always be the index of the
item. But when you postback, if you get the MobileListItem, it's Value
property will be the value you set.

E.g. on client side, sel.options[0].value =3D "0"
But on server side, sel.Items[0].Value =3D "Value1"

Mayur,

I assume that you are using the RTM versin of the Framework and the MMIT?

Please post both the COMPLETE aspx page and the codebehind. It might help if we can replicate your problem completely.
