如何在c＃后面的代码中添加带有objectdatasource的gridview？

Question

I want to create gridview with code. My code is:

 GridView gdvList = new GridView();
 gdvList.ID = "gdvList" ;
 TemplateField tField = new TemplateField();
 BoundField dateBF = new BoundField();
 dateBF.DataField = "Date";
 gdvList.Columns.Add(dateBF);
 BoundField countResponse = new BoundField();
 countResponse.DataField = "CountResponse";
 gdvList.Columns.Add(countResponse);
 ObjectDataSource ods = new ObjectDataSource();
 ods.ID = "ods";
 ods.TypeName = "Project.BLLQuestion";
 ods.SelectMethod = "GetByGroupID";
 ods.SelectParameters["GroupID"] = new Parameter("inGroupID", DbType.Int32, "0");
 ods.DataBind();
 gdvList.DataSource = ods;
 gdvList.DataBind();    

this code does not work, and how to add TemplateField do :

<asp:TemplateField ItemStyle-CssClass="GridItemTemplateField">
    <ItemTemplate>
         <a href="Question.aspx?id=<%# Eval("ID")%>"><%# Eval("Content").ToString().PadRight(140).Substring(0,140).TrimEnd()+"..." %></a>
    </ItemTemplate>
</asp:TemplateField>

how can do it?

Answer 1

1. You need to set DataSourceID property of Grid, not DataSource .
2. There are no need to run DataBind() method of ObjectDataSource .
3. Ensure that both controls ObjectDataSource and GridView are added on Page .

Try this:

  ObjectDataSource ods = new ObjectDataSource();
  ods.ID = "ods";
  ods.TypeName = "Project.BLLQuestion";
  ods.SelectMethod = "GetByGroupID";
  ods.SelectParameters["GroupID"] = new Parameter("inGroupID", DbType.Int32, "0");

  Page.Controls.Add(ods);

  GridView gdvList = new GridView();
  gdvList.ID = "gdvList" ;
  gdvList.DataSourceID = "ods";

  BoundField dateBF = new BoundField();
  dateBF.DataField = "Date";
  gdvList.Columns.Add(dateBF);

  BoundField countResponse = new BoundField();
  countResponse.DataField = "CountResponse";
  gdvList.Columns.Add(countResponse);

  Page.Controls.Add(gdvList);

  gdvList.DataBind(); 

According to your second question. Try to replace TemplateField by HyperLinkField . Click here for details.
