question about databind in user control

[¥øÃZ½Þ]

Dear All

I have write a user control which is uses to popup a new browser and
inherited ImageButton

It have a user defined property named url

and in the aspx page, the code like this

<ctlopupImageButtonControl id="ctlButton"
runat="server"

url='page.aspx?parameter1=<%# DataBinder.Eval(Container,
"DataItem.Parameter1")%>&parameter2=<%# DataBinder.Eval(Container,
"DataItem.Parameter2")%>&'/>

In above case, if i pass <%# DataBinder.Eval(Container,
"DataItem.Parameter1")%> only, it can bind, however, if i bind the data with
some other string, it cannot bind the data to the property, is it possible
to bind the data to the property with string appended?

Thanks

When you're databinding a property....you can only have a databinding
expression or a string expression....not a combination of both.

so.....try this:
url='<%# "page.aspx?parameter1="+DataBinder.Eval(Container,
"DataItem.Parameter1")+"Parameter2="+DataBinder.Eval(Container,
"DataItem.Parameter2") %>'
