So I have a page to edit employees.
Here is my view model:
[code]....
I'm not sure why this is happening. The dropdown is loaded correctly when I navigate to the page, but not when the view is redisplayed.
I have house_info table in database and I have dropdownlist in my page that bind it from Shoppingcenter columns from house_info table...
in Shoppingcenter column in some rows are data and some rows are NULL
now when I bind dropdown list it shows space in first Item after that it shows other Item that bind from house_info table I mean in dropdownlist shows NULL value (Space) that is in Shoppingcenter column
below is SP
ALTER procedure [dbo].[selectcentercityS]
@city nvarchar(30)
,@region nvarchar(5)
,@district nvarchar(30)
[Code] .....
I don't want it shows space in dropdownlist. What should I do?
I have a Gridview showing the MemberLastName, MemberFirstName, MemberBirthYear, MemberGender, MemberRelationship.
During Edit mode, I have managed to display a DropDownList for the Relationships.What I am trying to achieve now, is that, based on the Gender of the member I would like to limit the items in the Relationships dropdownlist.
e.g if the Gender is Male, then only display Male Relationships
What is the best way to achieve this scenario?Here is my snippet of code for the event. The code is commented out as it throws an exception.

I have a webForm which host a gridview and a formview. The formview is used for showing/editing a record which the user Select from the gridview.
In the formview Edit template I used DropDownList controls with
SelectedValue='<% bind("datafield")%>'
for enabling the user easier interface. A few of the DropDownList controls need to have a list of 100 items and I want to load the items from code behind and not from the aspx.
I tried to update the DDL's from FormView.Load, FormView.ModeChanging, FormView.PreRender but
nothing I am getting an error like this:
[code]....
How do I load the DropDownList controls with items BEFORE the form databinding occurs.
In the detailsview, I set a edit item template (a bounded dropdownlist control). But in database there are some data not set to a value (null). After clicking edit button in detailsview control I get the error about the value problem (Because after populating the dropdownlist, there is no item as null in it. )How to set dropdownlist selected index when the data is "null"?
View 6 RepliesI have a collection of items in a model that I am looping through to display a very simple editable grid like this

but the values typed in in the textboxes do not appear to be anywhere in the model post data , does anyone have any pointers , this mustbe a common scenario and just cant find solution.
I have the following codes and the test value is always null in the controller after the post. What is wrong and how can I correct it?
The values of Color, Size, Clothes are posted with the expected values. Though Data.test contains the values, I`m having Object {test=}, in firebug and test is null in the controller. why is that so?

I'm trying to pass post data from one page to the next but PreviousPage always equals null.This is what I have in the original page (inside an updatepanel
<asp:Button ID="mmGo" runat="server" Text="Merge" PostBackUrl="~/Default2.aspx?action=merge"/>
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<%@ PreviousPageType VirtualPath="~/Default.aspx" %>
[code]...
I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)

i have a web for and want to 'get' it to another page.. is there anyway to submit it without posting the viewstate and other bits i dont want? or should i be catching the submit button click and redirecting with a querystring i build myself

protected void Delete_Click(object sender, EventArgs e)

string strConnectionString = ConfigurationManager.ConnectionStrings["SqlServerCstr"].ConnectionString;
[code]...
Action method takes as id parameter and returns 2 lists (eg. List<object1> and List<object2>) of objects back to the view. In order to achieve this, the viewmodel is created as below;
ViewModel

Int id;

I have a page with two forms on it. The first form is a "Search" form and does not have the runat="server" attribute. It is merely meant to post some search criteria to another page on the site. The second form is the standard "aspnetForm". Inside that form I have a ModalPopupExtender... Within the ModalPopupExtender there are two buttons that should postback to the server when they are clicked by the user. My problem is that when the buttons are clicked the page posts back to the "Search" form... The only clue I have is that if I move the form to the bottom of the page (after my ModalPopupExtender), everything works fine. It seems that the extender uses the first form it can find on the page. Is there anyway to force it to postback to the correct form?

I have a user control I am adding dynamically. It has a link button and a text area on it. The containing div is hidden via style sheet (client side), and I use some jquery to pop it up in a modal. It is getting added in the init and the button click event is firing on the server. BUT the textareas value is not being set. On further inspection the field value is not even being sent in the form POST data. why the value is not being sent. The rest of the form values are being sent with no problems.
View 1 RepliesI'm posting data to a page called process.aspx that handles some business logic with the following code:
<%@ Page Language="C#" %>
<%
MyData.process(Request);
Response.Redirect("")
%>
this page I will be calling from a variety of pages. Is there some way of knowing from which page my form was submitted? I was thinking something along the lines of writing:
<form id="frmSystem" method="post" action="process.aspx?page=<%= %>">
However I don't know what to write in between the <%= %> to get the current page name.
how can i update another dropdownlist without posting back. i've seen the sample somewhere but its not doing anything.
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="false" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
<asp:ListItem Value="0">----Select----</asp:ListItem>
<asp:ListItem Value="101">General Admin</asp:ListItem>

I have an application that needs to post data to a url on the web and then receive an xml response. I have an HTML form (provided by vendor) that posts the data correctly, however when clicking the submit button the page is redirected to the post url and the xml is displayed in the browser. I need to do this on a postback within an existing asp.net project. Basically, the user will fill out the form, the form data will post to the url, the xml response will be received, and the appropriate values will be displayed on the screen. I've found a bunch of examples for doing this but I just can't seem to get my head around it. Can anyone point me in the right direction or explain how I should go about this?
View 7 RepliesIn my ASP.NET MVC 2 web application, I allow users to create custom input fields of different data types to extend our basic input form. While tricky, building the input form from a collection of custom fields is straight-forward enough.However, I'm now to the point where I want to handle the posting of this form and I'm not certain what the best way to handle this would be. Normally, we'd use strongly-typed input models that get bound from the various statically-typed inputs available on the form. However, I'm at a loss for how to do this with a variable number of input fields that represent different data types.A representative input form might look something like:
My date field: [ date time input
control ]
My text field: [ text input
field ]
My file field: [ file upload
control ]
My number field: [ numerical input control ]
My text field 2: [text input field ]
etc...
Ideas I've thought about are:Sending everything as strings (except for the file inputs, which would need to be handled specially).Using a model with an "object" property and attempting to bind to that (if this is even possible).Sending a json request to my controller with the data encoded properly and attempting to parse that.Manually processing the form collection in my controller post action - certainly an option, but I'd love to avoid this.Has anyone tackled an issue like this before? If so, how did you solve it?Update:My "base" form is handled on another input area all together, so a solution doesn't need to account for any sort of inheritence magic for this. I'm just interested in handling the custom fields on this interface, not my "base" ones.Update 2:Thank you to ARM and smartcaveman; both of you provided good guidance for how this could be done. I will update this question with my final solution once its been implemented.
I have a form as
<form action="" method="post">
<input name="Descripcion" type="hidden" value="" id="Descripcion" runat="server" />
<input id="Submit1" type="submit" value="Comprar" />
Instead of clicking on submit button i want that the form should be posted without clicking submit button with hidden fields
I have view that dynamically adds multiple partial views with a foreach statement with the standard <%Html.RenderPartial("partialName", model); %> . The partial view control has just a label and textbox control. When I view the source html generated it correctly has a single form control around all the multiple labels and textboxes. My single submit button, inside the form though does not send any of the form data back to the controller though when using FormCollection.

For example in my datalist if Eval("OptionJ").Tostring = Null I would like the function GetVisible to set visibility of the radio button to false like so:
<input name="Q<%#Eval("ID")%>" type="radio" value="J" visible="<%# GetVisible(Eval("OptionJ").ToString()) %>">
<%#Server.HtmlEncode(Eval("OptionJ").ToString())%>
</option><br />
I then have a codebehind function like so:
Protected Function GetVisible(ByVal Evalresult As String) As String
If Evalresult = Nothing Then
Return "False"
Else
Return "True"
End If
End Function
I have also tried checking EvalResult = String.empty
In the outputted html the visible status is being set to false...
<input name="Q3" type="radio" value="J" visible="False">
But it is still displayed on the page!
I'm trying to update items in my SQL database from a ListView. It works, but all entries in the database update. Not just the one I'm working on. I backed up the database prior to testing, so there's not any issues there.This is how my SqlDataSource UPDATE command is setup:
SQL Code:
UPDATE entries SET duration = @duration, checkinDate = @checkinDate, receivedBy = @receivedBy, cosmeticDmgIn = @cosmeticDmgIn, STATUS = N'closed'
I don't have any code setup to update the database, which is probably the issue.When I load the ListView, select edit, type in my edits, and click "Update", all the rows in my database, for that column, are updated with that data.I tried inserting the parameters manually, within the ItemUpdating event, but it never works.
