Changing Datalist items at run time

[sanju]

Hi ,

I am displaying 5 photos of a user(getting image path from database) and
binding them to hyperlink control and adding that Hyperlink control to
Datalist container in code behind file.

Now I want to change last 2 photos of user with another image while loading
the page.

My situation is "I want to hide/mask photos of user depending on the
permission level of who accessing the website.if one is paid member i want
to display all or for free members i need to display few.

............... . code ......

try

{

DataList1.ItemT emplate = new DatalistHyperLi nkColumn();

DataList1.DataS ource =ds1;
DataList1.DataB ind();

}

catch (Exception ex)

{

Response.Write( ex.ToString());

}

finally

{

PhotosConnectio n.Close();
}

}

public class DatalistHyperLi nkColumn : ITemplate

{

public DatalistHyperLi nkColumn()

{

//Add constructor stuff here

}

public void InstantiateIn(C ontrol container)

{

HyperLink hpl = new HyperLink();

hpl.DataBinding += new EventHandler(th is.BindLabelCol umn);

container.Contr ols.Add(hpl);

}

public void BindLabelColumn (object sender, EventArgs e)

{

HyperLink hpl1 = (HyperLink)send er;
DataListItem container = (DataListItem)h pl1.NamingConta iner;

String strVals =
Convert.ToStrin g(DataBinder.Ev al(((DataListIt em)container).D ataItem,
"ThumbImagePath "));

String lImagePath =
Convert.ToStrin g(DataBinder.Ev al(((DataListIt em)container).D ataItem,
"LargeImagePath "));

int pCount1 =
Convert.ToInt32 (DataBinder.Eva l(((DataListIte m)container).Da taItem,
"photocount1")) ;

hpl1.ImageUrl = "Photos/"+strVals;

hpl1.NavigateUr l = "Photos/web/" + lImagePath;

}

You need to handle ItemDataBound event. In the event handler you can check
the permission level and hide/mask the photos in the item accordingly.
