Forms Data Controls :: Button Event Inside ListView Is Not Triggering Correctly?

Mar 16, 2011

I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.

In the last column I have a button that calls my Search function and filters the records according to the inputs.


My Search function for now only displays a text inside a Label at the top of the page.

When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.

I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.

Forms Data Controls :: ListView Not Recognizing ItemType Correctly?

Sep 20, 2010

I thought I finally had this cracked but now I want iterate through the records in my listview and do different things depending on whether the record is displaying existing data or is a blank, new record. Easy, right? Here's my code:


The problem is that the listview doesn't seem to recognize the insertitem as such. Obviously I don't really want that message box in there but it was just to test whether the insertitem was being picked up. The message box is never displayed.I also tried a simple iteration through the listview items with a message box popping up on each item displaying the item type. It said 'DataItem' every time, never 'InsertItem', even though there is definitely and insert item there!!

Custom Server Controls :: Button Triggering An Event In A Custom Webcontrol?

Nov 16, 2010

I built a webcontrol showing a complex user interface with a lot of javascript. Basically my webcontrol is similar to : [URL]

Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.

Forms Data Controls :: Populating DropDownList Inside A ListView Inside A FormView

Jan 16, 2010

I have the following (abbreviated) code:

<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />

When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

Forms Data Controls :: Showing Linq Result Values Inside Dropdownlist Inside Listview

Jun 22, 2010

I have a listview that is showing its result by using a linq query. The linq query goes like this.


* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.


And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):


I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

Forms Data Controls :: Formview Button Visibility Not Working Correctly?

Apr 17, 2010

I have a formview that displays user info from a dropdownlist. One account may have many users, but one account Primary. I am trying to disable the Edit/Delete button in the formview if the selected ID is the account primary. The problem I get is this.

Step 1: page_load - the primary user is displayed by default, but the delete button is enabled - not right

Step 2: I use the dropdownlist to select another user (not the primary) - everything's fine

Step 3: I then select the Primary User, the Delete Button is disabled - perfect

Step 4: select another user, delete button still disabled - Not right.


1. As you can see my sqlSelect Parameters are bound to the DropDownList.SelectedValue, but is t seems like my if statement for comparing selecteduser to varAdminID doesn't work except once.

So to help debug, i added a label control that displays the selected userID, but on page load the label is blank. but it displays the first record on the list anyway. so if this is the reason for not disabling the delete button on page load then why later does it not reable the button when the user is not the primary, and the UserID is displayed on the label and it is not the primary userid?

Forms Data Controls :: How To Disable Button Inside EditItemTemplate Inside DetailsView

Jan 20, 2011

I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)

What I want is to Disable the button, if my boolean is 1 (true).

First I tried to convert my boolean value to text:

onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'

But got an error:

CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>

So another trial I did was to CAST the data from the database to be the text that I want, like so:

SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....

And my code changed to:

onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'

But got this error:

System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
at ASP.manager_aspx.__DataBinding__control74(Object sender, EventArgs e) in c:Documents and SettingsAdminMy DocumentsVisual Studio 2010ProjectsWebManager.aspx:line 219
at System.Web.UI.Control.OnDataBinding(EventArgs e)
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBind()
at System.Web.UI.Control.DataBindChildren()

So I wonder, is it possible to change the "Enabled" property based on by boolean value?
