Forms Data Controls :: Referencing Control In Javascript For Both EditItem And InsertItem?
Jan 3, 2011
I am using a CustomValidator to compare two textbox control values in the form view. These values are not required but must be compared if a valuue is entered. The same two controls are defined in both Edit Item Template and Insert Item Template. The formview default mode is Edit.
The javascipt for the custom validator works when in Edit mode. However, when the form view is Insert, the javascript throws an error of NullReferenceException. how I can adjust my code so that the client-side javascript works for both Edit and Insert mode?
The form view is in a content page. The script is in the Head content placeholder
<script type="text/javascript">
<!--
function cvSecondaryEmail_Validate(source, args)
{

Im going to attempt to explain this as short as possible.I have a student registration page.There are two ways you can add a new student:1)'Add New Student' button in the emptydata template field of a detailsview )When the detailsview is actually populated just click the 'insert' linkProblem is I need two cancels buttons that do different things depending on which scenario above is enacted. I tried to state: When "Add New Button" is clicked show one cancel button and not show the other.I have both cancel buttons showing as of now, and they are both setup to do the different things that I want them to do just cant get them to be visible or not visible depending on which button is clicked.

My displaycloud.aspx page contains two databound data lists, each for displaying a tag cloud. The datalists have an EmptyDataTemplate that holds an empty label if nothing is retrieved from the db. I am trying to display the message 'Please Log a Story', by using the code below on the companyadmin page, but I am getting an error (the controls are not on the same page). How can I reference the labels positive_tags and negative_tags from displaycloud.aspx in companyadmin.aspx? Also, I want to redirect if the EmptyDataTemplate is not executed as shown at the very bottom of the page.displaycloud.aspx:
<EmptyDataTemplate>
<asp:Label ID="positive_tags" runat="server" Text=""></asp:Label>
</EmptyDataTemplate>

I have a simple EditItem Template within a Formview that I am using to add a record to a table. There is one field in the form that I would like to assign a variable to. I cannot figure it out. I do not see any properties in VS2008 that allow me to assign the value.
The value that I am assigning is an item number, wich is the primary key in the table that I supply on the form.

I want to use a dropdownlist control as paging options (50, 100, 150, 200) for a GridView control so I can reuse the user control on other pages that uses paging.The dropdownlist control will be in the user control page and the GridView will be on the host page. How do I reference the GridView control generically from the dropdownlist in the user control to set the PageSize property of the GridView control upon selecting one of the dropdownlist options. Any advice and if there are other means to accomplish such tasks to allow reusability.

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

I've looked all over for this answer and had to resort to several resources. I wanted to post this here because it was so hard for me to find a simple example. If it exist other places then please excuse my post and put references to it on a reply.
So, How do I return the Primary Key Identity when I click the control with the 'Insert' command on a FormView? (With very least minimal code) Help me if there's a quicker way.
<InsertItem>
<SqlDatasource ID="sqlSource">
<InsertCommand = "INSERT INTO ... ; SELECT @ID = Scope_Identity()">
<InsertParameters>
<asp:Parameter Name="ID" Direction="Output" Type="Int32" />
</InsertParameters>
</SqlDatasource>
</InsertItem>
Protected Sub sqlSource_Inserted()
Dim cmd as System.Data.Common.DbCommand = e.command
Dim strID as String
sqlSource.InsertParameters("ID").DefaultValue = cmd.Parameters("@ID").Value.ToString()
strID = sqlSource.InsertParameters("ID").DefaultValue.ToString()
lblResults.Text = strID
End Sub

How can I work around that? Should I put all my scripts and CSS files into the root directory, is that a preferred solution?

I have a DataList with controls in the Header that are used to filter the DataList. Everything works correctly until I try and edit the filtered DataList. Having set the EditItemIndex, I then need to read the values from the header filter controls to ensure the Bind returns the same collection of rows. I am calling a function that should return the Header DataListItem so I can get the filter values if set. The problem is the DataList Item collection does not seem to have the HeaderItems in it.

I have a dropdownlistbox which references a specific column for a table in my database. After I select the proper id from the dropdownlistbox, I should press the submit button to see the name of the customer populated in a text field who references the id number for the dropdownlistbox. However, I am having trouble referencing a different column within the table. I can only view the selected value from the dropdownlistbox in the text box.

I' working on an Office Supplies website for a college course I'm doing. I have most of the website created, I'm just working on the shopping cart element of it now.
When the user goes to check out, I have a Gridview displaying the items the user wishes to buy as follows, it contains 3 columns, REF NBR, Product Name and Quantity, when the user clicks on the 'BUY NOW' button I want to take all the reference numbers from the Gridview and search teh database and deduct the Quantity from the number of items in stock.
I know I'll have to have a loop to read through the gridview, but how do I reference the contains of the Gridview REF NBR cell ?

I thought this would be easy but i cant find what i am looking for online
I have 2 pages, the first 1 has a button that opens another page. On this 2nd page the user selects a picture. When the user selects a picture the form closes. When they select a picture i want the image control on the first page to change.
I'm not sure how to do this, i guess i could set the image path as a session variable and reload the first page but again i'm faced with the problem of how to reference the first page from the 2nd

We are currently developing an ASP.NET MVC application which will be deployed on a corporate intranet, with a slightly-modified customer facing version available on the public internet.We're making use of a number of external javascript libraries (e.g. jQuery) and a discussion has come up regarding referencing the libraries - should we reference them from an external source (e.g. via the Google load jQuery method) or keep our own version locally and reference from there?The project manager is a little concerned about having a 'dependency' on Google (or whoever) if we reference from there, and thinks that having our own copy of the library makes us more independent. On the other hand, I have heard there are a number of advantages to letting someone else host the library - for example, they handle versioning for us, Google aren't going anywhere anytime soon...
(for the purpose of the discussion assume the intranet we're hosting on has external access - obviously if it turns out it doesn't the decision is very much made for us!)So. Does this matter? And if so, what should we do and why?(I appreciate this is subjective - but it would be very useful to get advice from anyone with experience or thoughts on the matter. Not sure if this is a candidate for community wiki or not, let me know if I should have put it there and I'll know for future!)

I have created a class within the App_Code called shared_methods.vb where I use methods that are frequently used within several pages.
I have a hyperlink control within the masterpage that i want to change the NavigateUrl depedning on what page. Just for better coding i would like to define the variable holding the hyperlink with my shared_method.vb.
I have:
Dim hl_back As HyperLink = CType(Master.FindControl("hl_master_back"), HyperLink)
This works within a page but not within shared_methods.
