asp.net c＃在gridview超链接中显示几个字符

Question

Sorry in advance for the bad title!

I have a gridview where i use sqldatasource

The gridview has a field called cover letter and it is a link button The title of the link button is view cover letter

<ItemTemplate>
 <asp:LinkButton ID="cat" runat="server" CommandName="cat" CommandArgument='<%# Bind("Id") %>' >View Cover Letter</asp:LinkButton>
 </ItemTemplate>

when i click on the view cover letter link a new window popup displaying the content of the cover letter

Now what i want to do is change the text of the link button from View Cover Letter so it display like the first 10 or 20 characters of the cover letter and when i click on the link it will show the full content of the cover letter in the new window.

so it will be something like this:

How can I do such a thing?

Answer 1

You can Use this: But make sure that you have some content in your cover letter content.. that was the reason you get the error.

     <asp:TemplateField HeaderText="Cover Letter">
        <ItemTemplate>
            <a href='../Pages/CoverLetter.aspx?ID=<%# Eval("cover_id")%>' target="_blank" style="color: blue; text-decoration: underline"><%# Eval("cover_content").ToString().Length>10 ? Eval("cover_content").ToString().Substring(0,10):Eval("cover_content")%></a>
           </ItemTemplate>
 </asp:TemplateField>

Answer 2

所以你的代码会像

<ItemTemplate> <asp:LinkButton ID="cat" runat="server" CommandName="cat" CommandArgument='<%# Bind("Id") %>' Text='<%#Eval("coverLetter").ToString().Substring(0,20)%>'>View Cover Letter</asp:LinkButton> </ItemTemplate>
