Forms Data Controls :: How To Add Dynamic Templates And Edit Templates In Gridview
Feb 1, 2011
i am using two tables for salary components like bonus,hra,ta,da.one is salary lookup table for viewing which components are chosen and according to this salary table is created dynamically.i want to view data fields of salary table in gridview and update thier value.
now problem is that how to create template field and edit template field for updating fields of salary table because field of the salary table changing every time as it is creating dynamically.
I would like to change the layout of the edit and insert templates to show multiple columns (instead of the default 1), and make the required fields show in the first column. Please point me in the direction I need to go.
I am using a formview on main web page and the Item template displays my data correctly but I get and error when I try and link to the edit or insert templates.This happens on our remote tesing server only.On my local machine running the page on the local server in VS 2010 everything works fine.But then doesn't it always work on your local machine.I might also mention that I am compiling for asp.net 4.0. Here is the stack trace :
System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'MYCORPABIGWEB01$'. at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()
I have recently found this snippet of code but I am unable to get it to work. Does anybody know if the $index syntax has changed in the latest version of the client templates?

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate() If Not Page.IsValid Then e.Cancel = True End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating Page.Validate() If Not Page.IsValid Then e.Cancel = True End If End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I added a RequiredFieldValidator to my InsertItemTemplate, and it seems to be working fine. The problem I am having, however, is that now I cannot do anything else in the ListView (like edit or delete items) UNLESS the required field has a value. Is there some way I can manually do the validation when the user clicks the 'Insert' button on the InsertItemTemplate, or some other little trick I can perform so the user doesn't have to first type in a value just to delete something else in the list?
i am working on a project in which i have to create newsletters. We wish to give user functionality of editing the complete layout ( drag and drop if possible) I am able to achieve drag and drop with web parts but can't customise them much like adding richtext box and saving multiple copies of same page with different layouts. I then wish to enable user to send the html only part of page which contains dynamic layout.
I need to display the data using listView. I want the data to be displayed like this:
Student Name: John
Exam Grade MidTerm1 A MidTerm2 B
I want each item to looke like that. For this, I created a 'Student' class which has the Name and Exams(A list of Exam class objects) Properties. And the Exam class has ExamName and Grade properties. how I should specify the ItemTemplate and LayoutTemplate for the ListView??
All the writeups on ListView's EmptyDataTemplate say that it's for displaying the fact that no data records exist, which is logical; but the bad thing is that I've found nothing as a follow-up. In other words, I haven't been able to find any "now what?" once you (as the site user) find that there aren't any data records. I am led to then ask what the real purpose of the EmptyDataTemplate is if you can't do anything with it.
I added a button called "Add Your Photo" on the EmptyDataTemplate, which activates a ModalPopupExtender with an AsyncFileUpload. All this works fine in terms of uploading the file but nothing happens after that. I wonder if I should be starting instead in the InsertItemTemplate.
So, I need to know how to accomplish a couple of options: I need to start out in either the InsertItemTemplate or the EmptyDataTemplate. If I do the latter, I will need to know how to get from there to the ItemTemplate so the rendering can be displayed.
What code should I use to display the data--that is, how do I move from the EmptyDataTemplate to the ItemTemplate?
I have a Listview that is connected to an EntityDataSource. What I'm having trouble doing is showing fields of an association in the Item Template rather than just the id.
For example, what it currently shows:
Name: John Doe Race: 3
What I wish it would show
Name: John Doe Race: Caucasian
Some example code:
[Code]....
Obviously, I'm getting the number because Race_ID is an integer. What I'm less sure about is how to bind it or Eval it in some manner that will let me match that id to a name in the other table (which is associated). I've tried <%# Eval("Race.Name") %>' and a few other things to try to get a name rather than an ID but I always get either the id or nothing at all.
This is probably a dumb question, but I have to ask because I spend so much time editing my formviews and listviews. Is there a way to edit the default template setup for these controls, in the code or somewhere? When you drag them over you get the default text with textbox column names; then I spend over 30 mins editing each to look the way I want it to.
I know I can create standard templates for WebForms and save them as Exported Templates.
And is it possible to edit the default control when you drag them on to the page, to list certain attributes automatically. example (validation controls you always have to add ControltoValidate I would like to drag mine onto the page and it say controltovalidate="" and then all I do is fill in the blank. Intellisense is fine, but sometimes you get brain freeze after hours of web design and forget the needed attribute and you have all to go through all of the errors and mistakes.
The ultimate would be, to drag a FormView Control and when you Refresh the Schema, you get textboxes, label controls instead of text for column name, and divs for forms, and Image Buttons , I am sure there is an XML file that runs the code that you can edit or something.
OR
ASP Developers, When you develop the next ServicePack allow us to edit or create default templates to customize the default templates, in VS and VWD.
to force a table width in Formview control templates? I have created a table in the ItemTemplate that works fine but I can't seem to get the table to fill the entire width of the display area. I tried wrapping the entire FormView in a div tag and setting the width to 98% but it didn't work either. Aplogies in advance if this has already been asked. I found a lot of references to GirdView (which didn't help) and nothing helpful r/e FormView except the div tag suggestion.
Here is the code I am using for the ItemTemplate (VS 2008, VB [preferred], in a master page):
I extended gridview control to add some new features and it is working fine. However, when i come to asp.net page and add the control declaratively, the templates of the parent control that is GridView are not visible.
I declare like following and then i cannot see all templates provided by GridVeiw itself such Columns, HeaderTemplate etc .
i am trying to load images from the northwind database (categories table, images that are stored in the database) into grid view control. But it dosenot seems to work.
As apart of my learning, I want to learn more about the data controls in asp.net.I have used the gridview in situations where it is specifically bound to an sql data source and handles updates and deletes really easily, but I have thought of something that I want to model, however am not sure which control is best to use.
The situation I have thought about is a bank statement. Most bank statements have the transaction name/details in one column, then two columns for debit and credit and then a third column for a running balance.I have read about using a footer row for insertion records, but I imagine you would not have the same about of columns in a footer (insertion) row. I.e. A transaction would not have a debit and a credit entry field, only an entry field for the amount and a dropdown for debit/credit.
Would the gridview be the best control to model this situation on? Or is there another control that would be best used? The control won't be talking to a sql datasource, but probably a datatable in the codebehind.
What is the best way to use jQuery Templates with GridView to achieve similar functionality of an UpdatePanel, such as add/edit/delete data without PostBack?
I'm having trouble retrieving the value of a cell in a gridview.
I think it may have something to do with the item template calling a function since I am able to retrieve the values of cells that are not calling a function in the same gridview.
How can i extract the displayed value from this cell?
I am currently evaluating the use of asp.net and MVC for a new project (vs. web part or web form pattern). While I really like the MVC pattern and the ability to abstract the code from the UI. I have a specific requiremt to create a custom control that returns data in a pre-defined format. As an example for this project I need to have data returned in a listbox control where there listboxt items contain an image and then values from the DAL. I want to have control over where the image and values from the DAL appear in the listbox control. Using WPF I have done this using Data templates. Is this possible using ASP.NET and the MVC pattern or is this only possible using a web form/ web part pattern?
Update In doing some more reading it appears that I can control how the data would be rendered in the view using markup: As an example if I have a collection (products) that returns image, name, description, price I can render this in the view by writing:
I have a dynamically built gridview in which every row in editing mode has 2 dropDownLists, i set autoPostBack property of first list to true in order to change the other list values according to the first, but upon postBack, the gridview is not in edit mode any more.
I find the repetition of sets of controls for each of the EditItemTemplate, InsertItemTemplate, and ItemTemplate templates of a FormView to be tedious and risky, in terms duplicating layout and code etc. I would much rather create a xxxDetails user control, and use this in each template, cutting layout and code location down to one location.
However, this introduces several complexities for data binding scenarios. Are there any extablished patterns or practice guides for using user controls in these scenarios?
