Feb 17, 2011
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.

I'm still building). After loggin in, users are presented with 3 radio buttons (they work), and 3 cascading drop downs (they work). Below that is an AJAX Accordion with 5 panes, each pane has a tabpanel with 4 tabs, 2 of the tabs have gridviews that change based on who is logged in and the radio buttons and dropdowns above

I am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?

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)

I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?

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

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?

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 have two asp.net buttons inside a template (Expand and Collapse) I want to implement a simple client side javascript function to hide the expand button after press it and show the collapse button and vice versa.
<asp:Button ID="btnExpand" runat="server" CommandName="Expand"
CommandArgument='<%# Container.DataElement("Id")%>' Text="+" />
<asp:Button ID="btnCollapse" runat="server" CommandName="Collapse"
CommandArgument='<%# Container.DataElement("Id")%>' Text="-" />
I tried OnClientClick event but I didn't know how to get the sender button and the second button from javascipt because they're in a template and their IDs will be generated.
I tried also to change their visibility from the code behind in the server (by Visible property) but the problems is the event handler will be fired after the postback and the changes will not be applied in the client.

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

Other than that I wanted to put in the Edit, Update and Cancel functionality so I also put in this from the Gridview Smart Tag.
Following is the gridview aspx code can anyone tell me what I am missing here?

I have a GridView. I allow editing using:
[Code]....
As I allow editing of row, so I have GridView:RowUpdating(). In it, I check if the entered value is valid. If not, I have e.Cancel = true.
[Code]....
After I see the message box comes up, the textbox still stays the same. I expect the textbox will disappear just as if I have pressed the Cancel button. (By the way, the ClientUtil is a class someone has written for me.)
How do I make the e.Cancel = true works as if I press the Cancel button.

A TemplateField of a DetailsView can be assigned a value easily at any of many event handlers such as Load, PreRender, etc. when the page is loaded. However, after Insert or Cancel is clicked, all the fields are cleared. I cannot figure out how to assign a value to the field again in code-behind.
