c# - Binding a DataTable to Template Fields of a GridView -

i can bind datatable gridview auto generating columns, need display multi-lined cell 1 of columns. this, want use template field item template using textbox object. fill in datatable adding columns , adding rows. know datatable set right because shows data (except multi-lined cell) want it. issue getting gridview extract data based on column names , filling in template fields have set up. if turn autogeneratecolumns off 4 templatefield columns still appear (in correct amount according datatable too), blank, , if have set true, 4 blank columns appear 4 additional columns same headers contain data using defaults cell contains display information.

    <asp:gridview id="datagrid1" runat="server" autogeneratecolumns="false"     headerstyle-borderstyle="none" cellpadding="3" itemstyle-wrap="true" >     <columns>         <asp:templatefield headertext="code">             <asp:itemtemplate>                 <asp:label id="txtcode" runat="server" text='<%# eval("code") %>'>                  </asp:label>             </asp:itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="title">             <asp:itemtemplate>                 <asp:label id="txttitle" runat="server" text='<%# eval("title") %>'>                  </asp:label>             </asp:itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="class">             <asp:itemtemplate>                 <asp:label id="txtclass" runat="server" text='<%# eval("class") %>'>                  </asp:label>             </asp:itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="history">             <asp:itemtemplate>                 <asp:textbox id="txthistory" runat="server" isreadonly="true" text='<%# eval("history")%>'>                 </asp:textbox>             </asp:itemtemplate>         </asp:templatefield>     </columns> </asp:gridview> 

the above portion of asp.net code relates gridview in question. following how set datatable , bind it.

datatable table = new datatable(); table.columns.add("code", typeof(string)); table.columns.add("title", typeof(string)); table.columns.add("class", typeof(string)); table.columns.add("history", typeof(string)); (int = 0; < index; i++) {     table.rows.add(docs[i].code, docs[i].name, docs[i].class.name, history[i]); } datagrid1.datasource = table; datagrid1.databind(); 

change .aspx code below

  <columns>         <asp:templatefield headertext="code">             <itemtemplate>                 <asp:label id="txtcode" runat="server" text='<%# eval("code") %>'>                  </asp:label>             </itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="title">             <itemtemplate>                 <asp:label id="txttitle" runat="server" text='<%# eval("title") %>'>                  </asp:label>             </itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="class">             <itemtemplate>                 <asp:label id="txtclass" runat="server" text='<%# eval("class") %>'>                  </asp:label>             </itemtemplate>         </asp:templatefield>         <asp:templatefield headertext="history">             <itemtemplate>                 <asp:textbox id="txthistory" runat="server" isreadonly="true"                          text='<%# eval("history")%>'>                 </asp:textbox>             </itemtemplate>         </asp:templatefield>     </columns>
