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.
I have a stored procedure and a function. I am connecting my FormView to the function and I am trying to insert a new record. I am not sure if the problem is the stored procedure, the fucntion or the FormView.
Hello all i have this little issue getting this to work, i have a dropdownlist in asp.net inside a formview and jquery cant find the control im guessing because its inside a form, this is what i got and it works on another page without a formviewi get this errorName 'Country' is not declared
let me know if some body tried to use a cascading dropdownlist inside a formview to be used in update and insert templates.known that my tables are like this:
Section: SecID SecTitle Category: [code]...
I need to create a formview to insert and update all my news but I need a cascading Dropdownlist to select a section and generate the related categories Note that I need to display the Sectoin and the Category Titles
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:
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
I have a dropdownlist inside a formview and I'm trying to do something on the selectedindexchanged event. but I'm getting the following error:
It looks like it can't find the dropdownlist because it is inside the formview. How can I find the event?- if there is such a thing.

I have a dropdownlist1 control in footer template, but when i go to edit command for editing an existing row. at that time. the footer dropdownlist box showing exact index which is selected in edit template dropdownlist box.

same datagrtid i am using for adding new rows via footer template and editing existing rows via edititem template.
how to make dropdownlist1 which is in footer template to selectedindex "0", when i go to editcommand. tried using itemdatabound but not working.
im having a quizz (a question and multiple answer related to the question) , i use an asp repeater to display the questionand a nested radiobuttonlist inside the item template for the related answer:
I do bind the the radiobutton on itemDatabound, i need to store the answer selected by the user, for that i used the following method:
but the rptAns referring to the radiobuttonlist (there is only one quiz at a time), the selectedindex always remain at the first index even when the user does change the selected radio button.i have made a check when on item databound to see if the page is a postback before opulating the radiobuttonlist.
In the website I'm building, I have a form that allows new users to register. Part of this page has mandatory address fields, and I use a postcode lookup field which returns a SuburbID and FullSuburbName (Suburb, State & PostCode) to a RadioButtonList inside an UpdatePanel.
I then handle the insert process in codebehind, and all this works perfectly on my New Account page.What I'm trying to do now, however, is replicate this functionality in the Edit Template of a FormView on my Manage Account page. The idea being that the user can view their current details in the ReadOnly view, then switch to Edit view to change their address (amongst other details of course). When the FormView changes to Edit mode, it should display the user's current PostCode in the textbox, and the RadioButtonList should display the available Suburbs for that PostCode, with the user's current SuburbID as the initial SelectedValue. If the user changes the PostCode and hits search, this refreshes the RadioButtonList with the new list of Suburbs, and once they have selected a new SuburbID this should get written back to the DB with the rest of the form (when they click Save I mean), using the SQL Data Source Update element. However, I simply cannot get this to work inside the FormView Edit Template and
So far, I have tried to handle the FormView's ItemCreated event and populate the RadioButtonList with the Suburbs that match the user's current PostCode, but if I do this with SelectedValue='<%# Bind("SuburbID") %>' in the RadioButtonList, I get the error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."If I then change it to have the SelectedValue populate from the codebehind, this works on the initial switch to Edit mode, but when the user changes the PostCode and hits search, I get a different error "'rblSuburb' has a SelectedValue which is invalid because it does not exist in the list of items."My thinking was that rather than binding the RadioButtonList I would just add the new SelectedValue in the SQLDataSource_Updating method, but it doesn't seem to like that either.
I am trying to capture the SelectedIndexChanged event for a drop down list I have put inside of a gridview control. It posts back fine, but does not go into my SelectedIndexChanged event handler. Here is my code
it is still not going into my myddl_SelectedIndexChanged() eventhandler.
Hi, i am newbie to asp.net. In my page there is a formview with sqldatasource. In which there is a dropdownlist wrapped with an updatepanel. What i'm trying to do is the re-bind ddlStudents after adding new row to the students table (using gridview and ajax popup extender-both working fine, i'm being able to add new )
<asp:UpdatePanel ID="ddlUpdatePanel" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:DropDownList ID="ddlStudents" runat="server" DataSourceID="sdsStudents" DataValueField="studentID" DataTextField="name" SelectedValue='<%# Bind("studentID") %>' > asp:DropDownList> </ContentTemplate> </asp:UpdatePanel> <asp:SqlDataSource ID="sdsStudents" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>" SelectCommand="SELECT studentID, name FROM tblStudents"> </asp:SqlDataSource> after closing the popup, Protected Sub btnClose_Click(ByVal sender As Object, ByVal e As EventArgs) If IsPostBack Then ddlUpdatePanel.Update() ddlStudents.DataSourceID = "sdsStudents" ddlStudent.DataBind() modalPopupPanel.Hide() End If End Sub
I am getting error;
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
One of the fields on my formview is a dropdownlist. When I go into edit mode the dropdownlist gets set to the correct value and works fine up to this point. Problem is I just can't see how to get the newly selected value of the dropdownlist to persist to the database when update is clicked. The DDL is a category list and I want to allow changing of the category for each record. Like I said I have it working so it displays the correct category for the record but if I change the DDL (change category) the new selected value doesn't get updated in the database. It just keeps using the binded value that was originally assigned to the selected value of the DDL. see code snippit
The above snippet is how I am binding the DDL. Now to not bore you with a ton of code paste I use various events of the formview to make sure the value displayed in the DDL is correct for the record that I am viewing at the time. All that works just fine. Where I need some pointers is the when I enter edit mode and change the DDL from say fire to ice it isn't getting persited to the database, all other info in the record gets updated just fine but the DDL never changes. I have tried several angles to getting this working and TBH my brain is yelling BREAK TIME.
I have added a table to my FormView Edit template for structure and a button that pops up a form for information.
When the button is clicked I want a check box in neighboring cell to become checked. But I am having problems in the VB code behind, establishing the name of the check box to change its state. Its something like this....
I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).
I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.
So I have tried both the Ajax Control Toolkit (which didn't work -- page didn't even display, got an error message about assemblies not registered.
AND implement use of the JQuery datepicker. Which I do have working OUTSIDE of FormView. Once I put it in FormView it doesn't display. Spent all day on this crap and have absolutely nothing to show for it but a bunch of code that doesn't do what I want it to....grrr...my inadequacies are irritating me (can you tell?)
Any help to get it working inside the Formview and bound to the Date field for my insertemplate. The FormVendorVisit is only used to insert the following fields: vendor_visit_id (identity / pk / not even visible on the formview inserttemplate), vendor_id, time_spent, date(this is where I am running into problems getting a popup calendar to select the date. My "ButtonInsert" in the formview takes care of the rest and works perfectly if I enter a date manually.
Here's my code on my aspx page:
My code behind vb page doesn't have too much in it yet and nothing with the datepicker: [Code]....
