Answer 1

页: 1

<%# CutString(Eval("Description").ToString(),50) %>

c)

public string CutString(string value , int len)
{
       // ....
}

Answer 2

在百页上,你可以直接发挥以下作用:

<%# Convert.ToString(Eval("Description")).Substring(0, 50) %>

“或”

In aspx page and make ProjectDataBound activity for the ListView

<asp:Label ID="lblDescription" runat="server" Text=""></asp:Label>

In code behind, create ItemDataBound

protected void lvData_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    if (e.Item.ItemType == ListViewItemType.DataItem)
    {
        Blog blg = (Blog)e.Item.DataItem;
        Label lblDescription = (Label)e.Item.FindControl("lblDescription");
        lblDescription.Text = blg.Description.Substring(0, 50);
    }
}
