Conditionally displaying elements of a repeater control

[Imran Aziz]

Hello all,

I am populating the contents of a repeater control using a database query.
In the repeater control I have a link , which I want to display or not based
on the current logged in user. I have a aspanel surrounding this link and
evaluate its value using the code below.

<aspanel ID="Panel5" runat=server Visible='<%#
((DataBinder.Eval(Container.DataItem, "nUserID")).ToString() !=
ViewState["intLoginUserID"].ToString() ) %>' Wrap="false" >



I have the user id of the logged in user in session and compare it with the
userid from the database, if both are same I need to show the delete link
otherwise not. Now the issue is that I cannot seem to reference with Session
variables or ViewSate variables in the front end aspx page. So how can I can
do the comparison then ?

Thanks a lot for your help.

Imran.

Try use the OnItemDataBound event in the repeater.

That way you can check the session

private void Repeater1_ItemDataBound(object sender,
System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
if(e.Item.ItemType != ListItemType.Header && e.Item.ItemType !=
ListItemType.Footer) //check its not the header or footer
{
string WotEver = (string)Session["MySession"];
}
}

Hi,

Try to comparasion on repeaters ItemDataBound Event instead of aspx page
becoz when you bind the repeater with datasource its ItemDataBound Event get
fired and and you will get the control of both session and your database
value as well.

Imran,

Try

<aspanel ID="Panel5" runat=server Visible='<%# IsLogged
(DataBinder.Eval(Container.DataItem, "nUserID")) %>' Wrap="false" >

and in the code

protected bool IsLogged (string id)
{ return id == ViewState["intLoginUserID"].ToString();}
