Repeater multi-template implementation

Description: it is similar to dynamic things. Different Types use different templates, different styles, and different fields.

For example:

A certain person published the log "study every day"

A certain person posted a photo of Qinghai Lake.

XXXXX

XXXXX

XXXXX

 

(The above XXX is the image position)

Implementation: ① SQL: Associate the required data with a view to a table

② C # :( the most critical, provided by the fruit er http://nonlyli.cnblogs.com/, the key point is to put different templates with placeholer, and then remove unnecessary templates in the onitemcreated event)

< ASP: Repeater ID = "Rptlist" Runat = "Server" Onitemcreated = "Rptlist_created" >
< Itemtemplate >
< ASP: placeholder ID = "Recordtype1" Runat = "Server" >
< Li > <% # Eval ( " Name " ) %> Published logs <% # Eval ( " Title " ) %> </ Li >
</ ASP: placeholer >
< ASP: placeholder ID = "Recordtype2" Runat = "Server" >
< Li >
<% # Eval ( " Name " ) %> Posted Images <% # Eval ( " Title " ) %>
< IMG SRC = "<% # Eval (" Imgpath ") % > "/>
</ Li >
</ ASP: placeholer >
</ Itemtemplat >

 

Protected   Void Repeaterincluitemcreated ( Object Sender, repeateritemeventargs E)
{
If (E. Item. itemtype = Listitemtype. alternatingitem | E. Item. itemtype = Listitemtype. item)
{
Datarowview Dr = (Datarowview) E. Item. dataitem;
Control C = E. Item. findcontrol ( " Recordtype "   + Dr [ " Type " ]);
E. Item. Controls. Clear ();
E. Item. Controls. Add (C );
}
}

 

In fact, visible may be better.

 

Code < ASP: Repeater ID = "Rpttest" Runat = "Server" >
< Itemtemplate >
< ASP: placeholder ID = "Itemname" Visible = '<% # (String) eval ("type") = "name" % > 'Runat = "server">
Name: <% # Eval ( " Content " ) %>
</ ASP: placeholder >
< ASP: placeholder ID = "Itemage" Visible = '<% # (String) eval ("type") = "Age" % > 'Runat = "server">
Age: <% # Eval ( " Content " ) %>
</ ASP: placeholder >
</ Itemtemplate >
</ ASP: Repeater >
