Question

I have a repeater that displays data from my Projects table. There are projectId, name and description. I use Substring(1, 240) on description. But sometimes the string is shorter than 240, so I get ArgumentOutOfRangeException. Can you tell me how to display the whole text if I get the exception. This is my code.

    <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:Panel ID="pnlDisplayProjects" runat="server" Visible="true">
    <center><h2><b>Проекти</b></h2></center>
        <asp:Repeater ID="rptrProjects" runat="server">
            <HeaderTemplate>
                <table border="1" cellpadding="2" cellspacing="2" align="center" width="80%" style="background-color:#F7F6F3;">
            </HeaderTemplate>
            <ItemTemplate>
                <tr>
                    <td align="left" style="width:40px">
                        <asp:Label ID="LblProjectId" runat="server" Text='<%# Eval("ProjectID") %>' />
                    </td>
                    <td align="center">
                        <asp:Label ID="LblName" runat="server" Text='<%# Eval("Name") %>' />
                    </td>
                </tr>
                <tr>
                    <td colspan="2">
                        <asp:Label ID="LblDescription" runat="server" Text='<%# Eval("Description").ToString().Substring(1, 240) + "..." %>'/>
                        <asp:HyperLink ID="HlMore" runat="server" NavigateUrl='<%#"~/Project/ViewProject.aspx?projectId=" + Eval("ProjectID") %>' Text="More" />
                    </td>
                </tr>
            </ItemTemplate>
            <FooterTemplate>
                </table>
            </FooterTemplate>
        </asp:Repeater>
</asp:Panel>

 protected override void OnPreRender(EventArgs e)
    {
        var table = Projects.GetTableWithProjects();

        if (table.Rows.Count > 0)
        {
            rptrProjects.DataSource = table;
            rptrProjects.DataBind();
        }
        else
        {
            pnlDisplayProjects.Visible = false;
            Master.PrintMessage("There are no projects.");
        }
    }

Answer 1

string dec = "description";
string result = dec.Substring( 0, dec.Length > 240 ? 240 : dec.Length )
