Question

我有一个带动态控件的gridview。资源名称是我从Active目录中获取的内容。搜索过滤器的工作方式是您必须输入它将搜索的查找的lastname，firstname和onlclick。如果有多个记录，将显示带有下拉列表的modalpopup，其中包含可供选择的选项。

问题是我无法将填充的下拉值填充到gridview中的文本框中。我需要在正确选中的行的文本框中显示此下拉值。

代码背后：

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

好的，所以，没有什么可做的。

必须添加此内容。

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

        mpFindPerson.Hide();
    }

在gridview行文本框中获取模态弹出值
