Entity Selection In View Without Using Dropdownlist?

Aug 31, 2010

I have an EditTask View for editing the following properties for a Task that I am modeling.

[Task Name]
[Project Name]
[Assigned Employee]

Task Name and Project Name are just simple text boxes.

I want Assigned Employee to be a selection from all the available Employee's currently in the database. Dropdownlist is not really an ideal option because there could be hundreds if not more possible employees.

I'm thinking a link to show a select employee grid listing in either a popup or another page where filtering can take place (b/c employee has other properties such as Dept) and the selection is made and the EditTask view is updated would be ideal but not sure. I'm new to ASP.NET MVC so I'm a little lost on where to start to implement this.

What is the best way to handle this UI scenario in ASP.net MVC?

VS 2008 Dropdownlist Selection Disables / Enables Another Dropdownlist

Aug 1, 2013

I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.

Then there is a second ddl.

If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).

Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:

Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>

It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:

Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}

MVC :: Error In View While Looping Trough IQueryable(of T) Entity From A SQL View?

Jan 18, 2011

when I'm building a menu in a view I get following error when code reaches <% Next item%> :

System.InvalidOperationException was unhandled by user code

Message=The value of a property that is part of an object's key does not match the corresponding property value stored in the ObjectContext. This can occur if properties that are part of the key return inconsistent or incorrect values or if DetectChanges

Source=System.Data.Entity

My view: (its a userview)

My Model

I use this way of looping frequent the only thing is that this is that this entity has a view as source and not a table, so I think it has to be related with that.

How To Redirect Based On Selection Of DropDownList

Jul 26, 2010

I have a TextBox1 and a Search button in my application with this following code:
protected void Button1_Click(object sender, EventArgs e) {
Response.Redirect("~\searchpage.aspx?PatientNRIC=" + TextBox1.Text); }

Which means, if the user type ONLY IC NO:S1234567D, then when click it will show the patient detailview. So I now I'm doing almost the same thing but now I have a TextBox2 and a DropDownList1. Inside DropDownList1, I have "Name", "IC No", "Test_Date". So for an example, I type "S1234567D" in the textbox1, and I choose "IC No" in DropDownList1 it should redirect me to a page of the S1234567D's patient detailview. How could I do my code?

Web Forms :: Get A Dropdownlist Selection Cached And Used Later In An App?

Jan 11, 2011

I have a page that searches and displays records. Users enter a record number and then select the type of record to display from a dropdownlist control. They then edit some data on the page, and the app does some calculations based on the type of record that is selected from the drop down. How do i get to successfully pass the value from the dropdownlist to the method that does the calculation to ensure that the right formula is used? Here is the code that I currently have.

[Code]....

then the code behind to do the calculation looks like this...

[Code]....

After stepping through the code, i noticed that when it gets to the "foreach" block, the value selected by the ddlRecordType dropdownlist is always the default which is "select one" and not any of the other selections that might have been selected.How do I get this to work, so that it can maintain the value selected from the dropdown and used in the code behind?

Populate A TextBox From A DropDownList Selection Javascript

Feb 7, 2011

I have a DDL and ASP.NET Textbox. I would like to populate the text box with the option I choose from the DDL. I need this to be instant and not use postbacks so it would seem JavaScript would be the obvious choice here. I have done quite a bit of searching but everything I have found seems to be for standard HTML (Selects and Inputs) and these do not appear to work with ASP objects:

<asp:DropDownList runat="server" ID="DDLSalesPerson" DataValueField="keyid" DataTextField="FullName" />
<asp:TextBox runat="server" id="txtSalesPerson" />
My DDL is populated from SQL in the code-behind page.

MVC :: Read Values From A Multiple Selection Dropdownlist

Jun 3, 2010

I have two ListBox in my ascx file, I fill them with some data (no problem here), I make them multiple and increase the size, below is my code.

[Code]....

I use some jQuery code to exchange element between them (Here too, no problem). My problem begin when I post my form, I'm unable to get the data from the DropDownList with attribute multiple or size. I tried in my controler to add a FormCollection parameter, I can see every element in my form except those select tag with more options than id and name. I tested to put a manual select tag in my code with only an id and a name then add size and multiple attribute, when there is only id and name I can get the value but when there are more I can't get my select tag in the FormCollection

Also I need to get all the value in the ListBoxand not only the ones who were selected. I have been searching answer for 2 fays now... Without success, I only find resource on how to show ListBoxbut not how to get values from them in mvc web site and I don't find any resources who talk about multiple selection ListBox, I think I'm a bad searcher but....

Web Forms :: DropDownList Selection Doesn't Show?

Sep 29, 2010

I've got two DropDownLists that are filled using a couple of SqlDataSources, like so:

[Code]....

The third DataSource, dsCriterias, is used to present a set of dynamically added DropDownLists depening on what's selected in the second DropDownList, subcategories. The set of dynamic DropDownLists are presented using this code:

[Code]....

The code works but there's little thing that's bugging me. When the page is first loaded the criterias belonging to the subcategory is not presented. I expect it to show the criterias but ther won't show until I make a choice in the categories-DropDownList meaning if I wan't the first subcategories criterias I have to choose different subcategory and then go back to the first one. It's a bit hard to explain.

An example: When the page is first loaded I get a category presented, eg. Vehicles. In the subcategories I get the alternatives "Bicycles", "Cars" and "Motorcycles". "Bicycles" will be the one presented when the page loads since the stored procedure used by dsSubcategories sorts the data by the subcategory names. The problem is that I don't get the criterias for the "Bicycles" subcategory at page load. To get them I first need to select "Cars" or "Motorcycles" and then choose "Bicycles".

I've tried putting a subcategories.SelectedIndex = 0 in in the OnLoad but nothing seems to do the trick.

Web Forms :: Dropdownlist Doesn't Remember The Value After New Selection

Apr 29, 2010

I have already spent two day to solve this on my own but for some reason I can't. Maybe I'm missing the live cicle of the dropdownlist. I hve a three dropdownlist that filter a gridview and the other two dropdownlists One is "Year" the other is "Country" and the other "Species" Each one of them is filter by the other two. So if I filter for one year it will only show me the species and countries that have records on that year. So I have to reload the gridview and all the dropdownlist.

What happend is that since I'm filling again the dropdownlist with less values he can't remember the previous one. I have tried with the events: DataBinding, Load Unload and Init of the dropdown list to force it to remember. The conclusion I have reach is that the databinding and the load have the dropdown list of the previous page. So if I do

String strYears = ddlYears.SelectedValue.ToString();
ddlYears.SelectedIndex = ddlYears.Items.IndexOf(ddlYears.Items.FindByValue(strYears));

And the year was on the index 4 but after changing the country the year is now index 3 he mantains the index 4 showing me another year.............................

AJAX :: ModalPopupExtender Warning On DropDownList Selection?

Nov 12, 2010

Is there a way that if certain items are selected in a DropDownList to fire up a ModalPopupBox. Basically if any value except for one value is selected, I want a popup warning them, are you sure?

I have the Popup Frame, I have the Popup Extender. I just don't know how to wire the two together using the TargetControlID. I don't want the popup to just automatically come up when the dropdownlist is selected but only if its not value "X".

I figured instead of doing this in parallel, I could check it after the fact when the form is posted using the extender.show() command but my program is crashing because the targetcontrolid for my modalpopupextender is null. I don't have a targetcontrolID in that case?

C# - Changing Dropdownlist Selection Causes Full Postback?

May 6, 2010

I have a search page with a TextBox that allows someone to type in a search term and press enter. (Which fires TextChanged). I have a DropDownList that specifies the kind of search that will be performed. It is defined in the markup as follows:

<asp:DropDownList ID="lstSearchType" runat="server" AutoPostBack="false">
<asp:ListItem Value="0">Last, First</asp:ListItem>
<asp:ListItem Value="1">Last</asp:ListItem>
<asp:ListItem Value="2">First</asp:ListItem>
<asp:ListItem Value="3">Liberty ID</asp:ListItem>
<asp:ListItem Value="4">E-mail</asp:ListItem>
<asp:ListItem Value="5">Telephone</asp:ListItem>
<asp:ListItem Value="6">Birthday (exact m/d/yyyy)</asp:ListItem>
<asp:ListItem Value="7">SSN (exact ###-##-####)</asp:ListItem>
<asp:ListItem Value="8">Address</asp:ListItem>
</asp:DropDownList>

As you can see, AutoPostBack is set to false, and there is no event hookup.

Pressing enter fires the OnTextChanged event for the TextBox, which performs a search and updates a GridView in an UpdatePanel. This UpdatePanel has its UpdateMode set to conditional and has one trigger: the TextChanged event of the search TextBox.

It's very simple.

And it works beautifully, almost.

Whenever I change the search type, the very next search does a full postback. All subsequent searches do partial postbacks (as desired) unless I change the search type again.

There is one exception to this rule: if I load the page and immediately change the search type, it doesn't do a full postback. So the first change of the DropDownList before any postback (full or partial) does not trigger a full postback.

Full Disclosure: I'm doing a lot of JavaScript to change the appearance of the gridview during async requests. I don't detail it here because it seems unrelated. This problem only occurs when a DropDownList with no JavaScript wired up is changed.

Web Forms :: Dropdownlist Selection Changes To First Item On Postback

Oct 19, 2010

I have been having some trouble with dropdown lists reverting back to selecting the initial item in the list after a postback once a selection has been made from the dropdown list. I have read up on this and found out that a "if not ispostback then" is required.This works fine when I add in all the items in the dropdown list manually like:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
ddl1.Items.Add("Select...") [code]....

However, I have over 250 items and so it is far more efficient for me to load then in by using part of a multidimensional array which is created from a text file - Definitive database.txt. I have been using the following code to do so:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
'loads the definitive database array[code]...

This loads all the items into the dropdown list perfectly, but now every time a selection is made, it reverts back to the inital item on postback even though i have included the "if not ispostback then" part.
