String Format Specifier in C# for with fixed length of strings in Gridview -

-

i trying display string fixed length (say 10 digits of strings) in grid view item template while binding, not find format specifiers string itself.

i can format specifiers (numbers{0:n}, floats & decimal (d), currency{0:c}, , date{1,8:yyyy} , percentage {0,3:p1},temperature: {0:f}, exponential, hexadecimal ... but not string itself)

i tried links: click here didn't work me.

my grid view have template field (item template)

<asp:templatefield headertext="notes">      <itemtemplate>       <asp:label id="label_note" runat="server" text='<%# string.format("{0}", eval("defect_note").tostring()) %>'  ></asp:label>         </itemtemplate>  </asp:templatefield>

i need display 'notes column' in below grid max 10 digits. if exeeds should not show (can show on tooltip) if less 10 can show content.

enter image description here

i wanted display notes columns printf(" %8s" ,&note) in c#. (in binding single line)

don't forget check null values.

notes.substring(0, math.min(notes.length, 10))
