Asp ModalPopupExtender Not Displaying Detail View?

Jul 26, 2010

am using a ModalPopupExtender within an updatePanel to show a detailView when a user selects a "Details" Button within a GridView.The problem is that when the button is selected the popup is not being displayed. I have stepped through the code and the mdlPopup.Show() method is being executed but the popup does not "Show" Could someone perhaps help me out with what is happening?Here is my Code:

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetRequests"
TypeName="RequestDAL" SortParameterName="SortExpression"></asp:ObjectDataSource>
<asp:ObjectDataSource ID="ObjectDataSourceDetails" runat="server" SelectMethod="GetRequestsDetail"

MVC :: 3 Master / Detail View Inserts New Detail Records Instead Of Updating Existing

Feb 6, 2011

article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object

[Code]....

The form collection comes back with the expected prefixes:

[Code]....

And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)

[Code]....

I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.

[Code]....

I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!

AJAX :: ModalPopupExtender Editing Rows In DetailsView (Master/Detail)?

Jan 23, 2010

I am at a stand still here. I have a GridView in which I'm moving the DetailsView (bound to a sqldatasource) to the ModalPopupExtender for Updating. DetailsView for the selected row is contained in an updatepanel with the UpdateMode set to Conditional. My Select function works properly, filling in the fields of DetailsView, but I cannot figure out how to get the Update function to work properly. I think what I am missing is a method to get the the key values and control values into the SqlDataSource UpdateParameters.

AJAX :: Modalpopupextender Not Displaying Correctly

Aug 3, 2010

I have a user control I created in asp.net 3.5. The user control has some buttons and a modal popup extender inside of it. I have added the control to one of the columns of my gridview. The propblem I am having is when I click on any other button in my control, then click on the button that displays the modal popup(client side), the grayed out modal popup area appears behind the grid, and I cant see nor access my panel. Here is my source for my user control.(I have tried playing with the z-index and other things, but nothing seems to work).

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ucParcels.ascx.cs" Inherits="UserControls_ucParcels"</textarea></p>

Gridview Not Displaying In Panel Associated With A ModalPopupExtender

Apr 4, 2011

I have two imagebuttons which are associated with a modalpopupextender. When I click imagebutton1, it opens up the panel and within that panel there is a grid which loads with the information. However, when I click Imagebutton2 it opens up the panel but does not display the gridview even though that gridview tag is under that panel.

find the code below:

<asp:Panel ID="PNL" ScrollBars="Auto" runat="server" Style="border: 2px solid Black; display: none; width: auto;
background-color: White; padding: 20px; text-align: center;" Height="444">
<asp:Label ID="LabelCount" runat="server" Text="Label" Font-Size="Large"
style="text-align: center"></asp:Label>
<asp:Button ID="ButtonOK" Text="OK" runat="server" />

AJAX :: Displaying UpdateProgress From Button In ModalPopupExtender?

Apr 29, 2010

I have a webform that displays a panel through the ModalPopupExtender. This panel has a button that will start a lengthy process, so I have an UpdateProgress attached to the button in the panel.

How can I hide the panel (displayed through the ModalPopupExtender) so that I can then display UpdateProgress? Currently, Button_getName will display Step2Panel. Then clicking on Button2 will display UpdateProgress behind Step2Panel. I tried hiding the panel in Button2_Click with ModalPopupExtenderStep2.Hide, but it didn't do anything.

AJAX :: ModalPopupExtender Displaying Behind A Listview Control ?

May 18, 2010

I have a web form with a modalpopupextender and a listView control that opens for editing and adding records. One of the columns on the listview is a linkbutton that makes a serve side call to show the modaldialpopupextender. At first, when clicking on the linkbutton in the listview the modalpopup displays over the listview, the page fades (via a CSS class) and it works great. When I open and close the listview for editing or change pages on the listview, and then try to show the modalpopup via the linkbutton, the modalpopup displays under the listview and the fading does not work properly. I am not too sure if this is a postback/javascript issue or maybe CSS?

Display List Of Values In MVC Detail View?

Feb 2, 2010

I am new to web apps, MVC, and LinqToSql. I created an MVC web app using the NerdDinner tutorial as a guide. I'm now adding many-to-many relationships to it. And am just running into walls at every step. I have a multiselect list in the Edit and Create views. For the Detail and List views I would like to list the selected values.

I have 3 tables: Company, Subcontract, and a link table CompanyToSubcontract. I have code which gets the guid of my selected companies from the CompanyToSubcontract table which is used elsewhere in my code. I do not know how to display it.

Should I write another function to get the Company names from the Company table? Do I pass the list of names to the SubcontractDetail view and then somehow loop through it there?

Same questions with the SubcontractIndex view. The Index view is in table format, I'd like to have a "Company" column which has a comma separated list of the companies for each subcontract row.

[Authorize]
public ActionResult Details(string id)
{
subcontract subcontract = subcontractRepository.GetSubcontract(id);
IEnumerable<Guid> cmpny = subcontractRepository.GetSubcontractCompanies(subcontract.subcontract_id);
if (subcontract == null)
return View("NotFound");
else
{
return View("Details", subcontract);
}
}
[Authorize]
public ActionResult Index()
{
var subcontracts = subcontractRepository.FindAllSubcontracts().ToList();
return View("Index", subcontracts);
}

Forms Data Controls :: Moving From One Field To Another In A 'Detail View' Form?

Jul 1, 2010

I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.

Is there someway that I can control the action of the "Enter" key so that this will not happen?

Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?

Forms Data Controls :: Master / Detail With Additional Detail Paging

Aug 6, 2010

I'm trying to setup is a News module with article listing paging and article detail paging. I have a GridView with paging that lists my articles just fine. In that list, some article titles have links that direct to an article detail page by passing in the articleID to the details page. I was able to setup my details page, which uses a DetailsView control, to use paging by using an ObjectDataSource with pageIndex and pageSize parameters from the querystring. Once on my detail page, I can use my navigation arrows to move through Next and Previous articles just fine.

No matter which article I click in my article list, my detail page always starts with pageIndex 0 and thus not the article I clicked on. I understand why that is because it's going by pageIndex value instead of articleID. What I need it to do is, set the detail to whatever articleID i pass in, then allow me to navigate Next and Previous to THAT particular article instead of starting me off from pageIndex 0.
