One option is to use template-based columns. Eg:
<asp:DataGrid.. .>
...
<ItemTemplate >
<%# ShowQDescriptio n (DataBinder.Eva l(Container.Dat aItem, "QID"),
DataBinder.Eval (Container.Data Item, "QDescription") ) %>
</ItemTemplate>
...
</asp:DataGrid>
In your code-behind, define a function named ShowQDescriptio n() as
protected string ShowQDescriptio n (int qID, string qDesc)
{
string linkTag = null;
if (qID == 1 || qID == 4 || qID == 5 || qID == 6)
{
linkTag = "<a href='answers.a spx?QID=" + ownerID.ToStrin g() + "'>" +
qDesc + "</a>";
}
else
{
linkTag = qDesc;
}
return linkTag;
}
Other option is to have the hyperlinkcoulmn as you have now, but enable or
disable it based on the QID. Use the above-shown technique to determine the
value for Enabled attribute of the hyperlinkcolumn
<asp:HyperLinkC olumn Enabled=<%#
IsEnabled(DataB inder.Eval(Cont ainer.DataItem, "QID")) %> />
IsEnabled will return True of False based on the QID passed to it.
Yet another option is to handle ItemDataBound event of the grid and handle
enabling hyperlink in the event handler.
Hope this helps.
