[bushi]

hi !
i have following code to display some text on a web form,after
getting it from database.

<asp:DataList ID="DataList1" runat="server"
DataSourceID="S qlDataSource1">
<ItemTemplate >
<asp:LinkButt on ID="links" runat="server" Text='<%#
Eval("links") %>' OnClick="LinkBu tton1_Click"></asp:LinkButton> <br />

<asp:Label ID="textLabel" runat="server" Text='<%#
Eval("text") %>' ForeColor="Dark SlateBlue"></asp:Label><br />

<asp:Label ID="urlsLabel" runat="server" Text='<%#
Eval("urls") %>' ForeColor="Dark SeaGreen"></asp:Label><br />

<asp:HiddenFiel d ID="page" runat="server" Value='<%#
Eval("page_ref" ) %>'></asp:HiddenField ><br />
<br />
</ItemTemplate>
</asp:DataList>

and i want to access the value of hiddenfield in my aspx.cs file for
some manipulation.fo r this purpose i'm using the following code:
for(i=0;i<DataL ist1.items.coun t;i++)
{
HiddenField hd = (HiddenField)Da taList1.Items[2].FindControl("p age");
string s = (hd.Value) as string;
}

selected item against my record.
any one have idea about it,plz rply me.

Good morning Bushi,

Take a look at your code again. You're looping through the items accessing
third item (Item[2]) ein every iteration. In addition to that, there is no
need for that as datalist has a property to check which item is currently
selected, it should be as following:

int index = DataList1.Selec tedIndex;
string value = String.Empty;

if (index >= 0)
{
HiddenField hidden = (HiddenField)
DataList1.Items[index].FindControl("p age");
value = hidden.Value;
}

Howdy,

There is no need to use hidden fields for this purpose. Use DataKeyFields
property to specify which column should be used as row identificator and get
its value via SelectedValue property and SelectedIndexCh anged event:

<script runat="server">
protected void DataList1_Selec tedIndexChanged (object sender, EventArgs e)
{
// i assumed page_ref type is string
DataList dataList = (DataList)sende r;
string pagerRef = (string) dataList.Select edValue;
// use the selected page ref value here...
}
</script>

<asp:DataList ID="DataList1" runat="server" DataKeyField="p age_ref"
OnSelectedIndex Changed="DataLi st1_SelectedInd exChanged">
<ItemTemplate >
<asp:LinkButt on CommandName="Se lect" ID="links" runat="server" Text='<%#
Eval("links") %>' /><br />
<asp:Label ID="textLabel" runat="server" Text='<%# Eval("text") %>'
ForeColor="Dark SlateBlue" /><br />
<asp:Label ID="urlsLabel" runat="server" Text='<%# Eval("urls") %>'
ForeColor="Dark SeaGreen" /><br />
<br />
</ItemTemplate>
<SelectedItemSt yle BackColor="red" />
</asp:DataList>

Hope this helps
