You mean like in the django admin ui ;).
I'm currently trying to implement that feature, i'll post the code here if I get it to work.
EDIT:
Ok, I got that to work, complete django style... It's kinda long to explain but simple in fact.
Files to create:
A admin_popup.master to have a nice popup page (copy the admin.master without the header).
A popup_Insert.aspx with admin_popup.master as master. (copy the Insert.aspx)
Modifications
To your admin.master.cs:
add this:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "refresh_fks", @"
var fk_dropdown_id;
function refresh() {
__doPostBack(fk_dropdown_id,'refresh');
};", true);
}
In your admin_popup.master, add these attributes to the body tag (it's used to resize the poup)
<body style="display: inline-block;" onload="javascript:resizeWindow();">
In your admin_popup.master.cs
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "refresh_fks", @"
var fk_dropdown_id;
function refresh() {
__doPostBack(fk_dropdown_id,'refresh');
};", true);
System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "resize_window", @"function resizeWindow() {
window.resizeTo(document.body.clientWidth + 20, document.body.clientHeight + 40);
window.innerHeight = document.body.clientHeight + 5;
window.innerWidth = document.body.clientWidth;
}", true);
System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "update_parent", @"function updateParent() {
window.opener.refresh();
}", true);
}
In popup_Insert.aspx.cs, replace these two functions:
protected void DetailsView1_ItemCommand(object sender, DetailsViewCommandEventArgs e) {
if (e.CommandName == DataControlCommands.CancelCommandName)
System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Close_Window", "self.close();", true);
}
protected void DetailsView1_ItemInserted(object sender, DetailsViewInsertedEventArgs e) {
if (e.Exception == null || e.ExceptionHandled) {
System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Close_Window", "window.opener.refresh(); self.close();", true);
}
}
In ForeignKey_Edit.ascx, add a LinkButton (ID=LinkButton1) and in ForeignKey_Edit.ascx.cs, replace that function
protected void Page_Load(object sender, EventArgs e) {
if (DropDownList1.Items.Count == 0)
{
if (!Column.IsRequired) {
DropDownList1.Items.Add(new ListItem("[Not Set]", ""));
}
PopulateListControl(DropDownList1);
LinkButton1.OnClientClick = @"javascript:fk_dropdown_id = '{0}';window.open('{1}', '{2}', config='{3}');return false;".FormatWith(
DropDownList1.ClientID,
ForeignKeyColumn.ParentTable.GetPopupActionPath(PageAction.Insert),
"fk_popup_" + ForeignKeyColumn.ParentTable.Name, "height=400,width=600,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,directories=no,status=no");
}
if (Request["__eventargument"] == "refresh")
{
DropDownList1.Items.Clear();
if (!Column.IsRequired)
{
DropDownList1.Items.Add(new ListItem("[Not Set]", ""));
}
PopulateListControl(DropDownList1);
DropDownList1.SelectedIndex = DropDownList1.Items.Count - 1;
}
}
And finally the two extentions functions I use (put it where you want to):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Web.DynamicData;
using System.Web.UI;
public static class Utils
{
[DebuggerStepThrough]
public static string FormatWith(this string s, params object[] args)
{
return string.Format(s, args);
}
public static string GetPopupActionPath(this MetaTable mt, string action)
{
return new Control().ResolveUrl("~/{0}/popup_{1}.aspx".FormatWith(mt.Name, action));
}
}
In your global.asax, register the new route by changing that line:
Constraints = new RouteValueDictionary(new { action = "List|Details|Edit|Insert|popup_Insert" }),
Ok I hope i didn't forgot anything... It certainly could be improved, but it works.
Ok I hope some people will fint that useful, it makes ASP.NET Dynamic Data a lot more better ;). I'm goind to take a look at many-to-many relationships now.
