how to control the number of text displayed in a label in a datalist???
can anyone suggest the code for this problem...if length of description exceeds 100 characters and a "show more" link to appear ("show less" is not necessary). Once "Show more" is clicked the full description should appear on the next page...

Have you done anything so far? Show some effort (code or searching)! As is it ain't a question...

<asp:DataList ID="DataList1" runat="server" Width="627px" BorderColor="Black"
BorderStyle="Solid" BorderWidth="1px">
<alternatingitemstyle bordercolor="Black" backcolor="#F7F7F7">
<itemstyle forecolor="Black">
<itemtemplate>
<tr>
<td>
<asp:Image ID="imgEmp" runat="server" Width="120px" Height="100px" ImageUrl='<%#Eval("photo") %>' style="padding-left:40px"/>
<asp:Label runat="server" CssClass="ShortDesc" Text='<%# Eval("news")%>' id="Label2" Font-Names="Trebuchet MS" Font-Size="Small" style="height: 138px; width: 400px" >

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/sub editor/subeditor_editor.aspx" Text="Read more..." ForeColor="red" />
</td>
</tr>

i tried this, but not helped me:
Text='<%# Eval("news").ToString().SubString(0,Math.Min(200,Eval("news").ToString().Length)) %>'

tried these too..
Eval("news").SubString(0,100)

word-break: break-all; word-wrap: break-word;
but 2.1 doesn't contain these properties

Use Item data bound event of data list .
Try to do some thing like this code.

C#

protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e) {
   if (e.Item.ItemType == ListItemType.Item) {
        Label lbl =(Label)e.Item.FindControl("panelPostDetails").FindControl("lblMorePictures");
        string tempString = lbl.Text;
        if(tempstring.length>100)
        {
          tempString=tempstring.subString(0,100);
          tempstring=tempstring+"...";
          lbl.Text= tempstring;
        }
   }
}

I have written this code as text. So if there is any syntax problem, please correct it.
