if statement

I have dataRepeater.

How can I do:

<ItemTemplate>
<asp:TableCell >
<%If viewState("type") = "3" then%>
<%# writeLine(DataBinder.Eval(Container.DataItem,
"name")%>
<%else%>
<%# writeLine1(DataBinder.Eval(Container.DataItem,
"name1")%>
<%end if%>
</asp:TableCell>
</ItemTemplate>

The problem is that when viewState("type") =3 then I have different
dataSource.

If statement doesn't work like I write.

Any idea?

Thanks,S

It is possible to do inline formatting, but as the formatting gets more
complex, it's better to do it in codebehind hooking into the ItemDataBound
event.

You can learn more on both methods at:
http://openmymind.net/index.aspx?documentId=8#4

basically though, to do it your way, I would do:

<asp:literal runat="server" visible='<%# (ViewState("type") = "3")'
id="x"><%# DataBinder.Eval(Container.DataItem, "name") %></asp:literal>
<asp:literal runat="server" visible='<%# (ViewState("type") <> "3")'
id="x"><%# DataBinder.Eval(Container.DataItem, "name1") %></asp:literal>

As you can see, each literal will be visible based on whether the condition
is true or false.

Again, I would urge you to look into doing this in the ItemDataBound event.

Thank you Carl.

Do you know when to use databinding control event?

Or you always use item_dataBound event?

Simon

Hi Karl,

I choose ItemDataBound event

In your example you declare dataItem as new owner:
Owner owner = (Owner)e.Item.DataItem;

In my example, how can I read the value of the first column, for example:

string column1;

column1=e.Item.DataItem(1);

or something similar?

regards,S

Well, you can use DataBinder.Eval() in your code behind like you would in
your aspx, such as DataBinder.Eval(e.Item.DataItem, "Blah")

or, you can cast DataItem to the specific type. If you are binding from a
dataset, datatabele or dataview, you would do:

DataRowView dv = ctype(e.Item.DataItem, DataRowView)

dv("Column1")
dv(0)
