Limiting Character Data

Question

I have problems in limiting my character data and adding a 'read more' in it.

I am using this code

<%--<asp:Label ID="Label1" runat="server" Text='<%# Eval("BookSynopsis").ToString().Length>=100) ? Eval("BookSynopsis").ToString.SubString(0,100) :Eval("BookSynopsis") %>'></asp:Label>--%>

but it doesn't work at all..

I want my book synopsis to be a limit of 100 characters and if it exceeds the 'read more' will be shown and be directed in 'details page'.

,.please help me. Thank you..

HI try like this. it may help you Text=' ' Tooltip=' '> Text=Read More Visible=' ' OnClick=ReadMoreLinkButton_Click> And code-behind protected bool SetVisibility(object Desc int length) { return Desc.ToString().Length > length; } protected void ReadMoreLinkButton_Click(object sender EventArgs e) { LinkButton button = (LinkButton)sender; GridViewRow row = button.NamingContainer as GridViewRow; Label descLabel = row.FindControl(Label1) as Label; button.Text = (button.Text == Read More) ? Hide : Read More; string temp = descLabel.Text; descLabel.Text = descLabel.ToolTip; descLabel.ToolTip = temp; } //including the original helper from the question with changes in signature protected string Limit(object Desc int length) { StringBuilder strDesc = new StringBuilder(); strDesc.Insert(0 Desc.ToString()); if (strDesc.Length > length) return strDesc.ToString().Substring(0 length) + ... + [Read More]; else return strDesc.ToString(); }

Hi Hanna See your code: ------------------------------------- =100) ? Eval(BookSynopsis). ToString .SubString(0100) :Eval(BookSynopsis) %>'> --%> ------------------------------------- Probably you've missed to put () after ToString which is causing the issue. You can modify it to ToString().Sub... and it will work. EDIT 1: Try this code: ------------------------------------- =100) ? Eval(BookSynopsis).ToString(). SubString(0100) :Eval( BookSynopsis) .ToString() %>'> ------------------------------------- Happy Coding :)
