在gridview行文本框中获取模态弹出窗口值

Question

我有一个带有动态控件的gridview。资源名称是我从Active Directory中选取的东西。搜索过滤器的工作方式是，您必须输入姓氏，名字和搜索字词，然后搜索。如果有多个记录，则会显示一个modalpopup，并在下拉列表中显示可供选择的选项。

的问题是，我无法得到填充到文本框出现在gridview的下拉值。我需要在正确的选定行的文本框中使用此下拉列表值。

后面的代码：

protected void gvProjectResource_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     if (e.CommandName == "Lookup") 
     { 
      GridViewRow clickedRow = ((LinkButton)e.CommandSource).NamingContainer as GridViewRow; 
      TextBox t2 = ((TextBox)clickedRow.FindControl("t2")); 

      DataTable dt = globalObj.FindPersons(t2.Text.Split(',')[0].Trim(), t2.Text.Split(',')[1].Trim()); 
      if (dt.Rows.Count > 1) 
      { 
       mpFindPerson.Show(); 
       ddlPersons.Items.Clear(); 
       ddlPersons.Items.Add(new ListItem { Value = "0", Text = "-Select User-" }); 
       ddlPersons.DataSource = dt; 
       dt.Columns.Add("FullName", typeof(string), "DisplayName + ' | ' + MSID"); 
       ddlPersons.DataTextField = "FullName"; 
       ddlPersons.DataValueField = "MSID"; 
       ddlPersons.DataBind(); 
      } 
      else 
      { 
       t2.Text = dt.Rows[0].ItemArray[0].ToString(); 
      } 
     } 
     if (e.CommandName == "Del") 
     { 

     } 
    } 

protected void btnSelectPerson_Click(object sender, EventArgs e) 
    { 
     TextBox t2 = (gvProjectResource.SelectedRow.FindControl("t2") as TextBox); 
     t2.Text = ddlPersons.SelectedItem.Text; 
     mpFindPerson.Hide(); 
    } 

ASPX代码：

Answer 1

行，所以，没有什么太多的事情。

必须添加此。

protected void btnSelectPerson_Click(object sender, EventArgs e) 
    { 
     TextBox t2 = (TextBox)gvProjectResource.FooterRow.FindControl("t2"); 
     t2.Text = ddlPersons.SelectedItem.Text; 

     mpFindPerson.Hide(); 
    }
