Brandon is right in his assertion that there are easier ways to do
this... For instance, if you were using a DataGrid you would have
access to the HyperLinkColumn field which would allow you to assign a
DataNavigateUrlField and a DataNavigateUrlFormatString to a "select"
hyperlink declaratively. The GridView control offers a HyperLinkField
for the same functionality.
However, since you are using a DataList (a lighter, but less powerful
control), you have other options. What you are presently doing is
handling the Click event of the LinkButton. This same eventhandler
will be executed for each "Select" button in every row. There will be
no way of distinguishing (atleast directly) which row's Select button
was clicked. For this reason, the Button and LinkButton controls have
CommandName and CommandArgument properties which can be used when
handling the ItemCommand event of the DataList. The ItemCommand event
has a parameter called DataListCommandEventArgs which can tell you the
index of the LinkButton that was clicked in the DataList.
Something like the code below :
---
ASPX code:
-------------------
//In the DataList ItemTemplate:
..
..
<asp:LinkButton ID="lnkSel" runat="server" Text="Select"
CommandName="Select" />
Code-behind:
-------------------
protected void DataList1_ItemCommand(object source,
DataListCommandEventArgs e)
{
if(e.CommandName == "Select")
{
string bID;
// Get the index of the row from which this event was raised.
int idx = e.Item.ItemIndex;
// Get the DataKey with the same index.
object thisKey = DataList1.DataKeys(idx);
if(thisKey != null)
{
bID = thisKey.ToString();
Response.Redirect("~/BookDetail.aspx?BId=" + bID);
}
}
}
