Forms Data Controls :: Hiding ListView Until Submit / First Navigate To The Page, The EmptyDataTemplate Is Shown?
Apr 9, 2010
I often have some controls (like TextBoxes) for input parameters at the top of a page followed by a ListView to show the results.
When submit is hit, the LIstView shows the results using ControlParameters in the SqlDataSource.
My problem is when you first navigate to the page, the EmptyDataTemplate is shown. This can confuse users.
What is the Best Practice for not showing the ListView or EmptyDatatemplate until there has been a Submit button press?

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?

There have been a few datapaging questions tonight, but mine is a bit different..
I have a regular datapager, in a seperate project it seemed to work fine with the same query and templates, but when I use it in my page, whenever the I try to page I get the emptydatatemplate when there should be data..
Here is my current ListView
[Code]....
I have tried binding data OnPreRender and setting the page properties under the OnPagePropertyChanging events.. still only getting my empty template whenever i navigate through the pages when there should be plenty of data..

I have a ListView control that only displays one record at a time. I have a LinqDataSource that can return one or more records. I have a function that determines the number of records and returns a psuedo random number between 1 and the number of records returned. When the page first loads, I want to display a random record. After that, I want the datapager to move the user normally through the records.
In my Page Load Event, if Page.IsPostBack is false, I get the random number. Let's say for simplicity I have 15 records and the randon number generated is 6. How do I tell the LinqDataSource to display the record at index 6?

I have the selected DataKey in session from the ListView. I am able to set the selection back when I comeback to this aspx page containing listview. But when the selected item in the listview belongs to some other page (not the first listview page) then I need to also set the selected listview page to the one, where my item belongs. I use a listview and a datapager (with template paging) How can I find, in which page my item to be selected exists?

I have a gridview which has paging enabled in it.
In my gridview I have a button which adds a new row to the grid. The problem i am having is that when the user clicks this add row button, it needs to go to the last page and add a new row there.
At the moment when I click the button i get an error saying - Index was out of range.
I'm sure this is because the method i am using doesn't know how to get to the last page... it needs to do this no matter what page the user is on
The method i use to add a new row is as follows: how i can adapt it to recognise the last page and row position in the gridview?

I have two tables: Book and author and they have one to many relation.One book may have more than one authors. Book table has Title column and Author table has AuthorName Column.
I have search page contains two textboxes: Title Textbox and AuthorName textbox to search the record.
When the user type something and hit the search button it display the Title when click the title ; it redirect to detailsPage.aspx Passing value ID.
[Code]....
Then in the Details page there are: Title, authors and other more from these table column.
My problem is:
When the user search and hit the search button, it display the number of matches Title only. I want to display authors related to this title in this page and other are same(when click the title go to detailspage.aspx)
How can I display the related Authors to each title in search display page (Not in details page, I know in details page) ?
If user search "The Letters and life" in the Title textbox and hit enter data should looks like:
1. Author: Payne Paddy, sed ran, der virma and Caroline Barron.
Title: The Letters and Life of Elizabeth Despenser, Lady Zouche (d. 1408) [her letters and will provide a glimpse of her personal
2. Author: ayne manu, edd saan and fer wertu.

I'm extracting data from a webserivce.
This is my select statement to retrieve the data:
string cmdstr = "select title, titlefr, racpnr, racpmodeltype from onl_wgn where show = 1 order by onl_kl, racpnr";
I got 4 groups of onl_kl. Now I want to show each group in a tab of the jquery tabcontainer.
I can pass the data in a dataset from my webservice to my webapplication and databind it to a listview, but I don't know how to seperate the data into the 4 tabs? Is this possible in a way with a listview or using other datacomponents?
If not, should I make 4 select statements in my webservice and send 4 datasets to my webapplication and bind it to 4 listviews each in 1 tab? If so how I can pass a list of datasets from a webservice to a webapplication?

I also have a working application that popukates my datagrid with valid data rows from my DataBase. What I cant figure out is how to get each of the hyperlink lables to NAVIGATE to the correct and corresponding aspx page!
For example I have 5 rows in the datagrid and each row has its own hyperlink, each row contains contact and a short profile on 5 diffrent companies. For example when i click on let say row 3 that has (eg) Jimmy's Big Prawn's Restaurant listed in the the datagrid, I want to be navigated to a webform page dedicated to Jimmy's Big Prawn Restaurant.
[Code]....
I am guesing it has to do with the bolded text above, but "details.aspx" is just an empty webform, I would like the hyperlink to point to (eg) JimmBigPrawnRestaurant.aspx.

I would like to ask a question about hiding a drop down in my gridview. I have a gridview and I have a drop down list to control the page size of that gridview. when there is data in that gridview, it is fine for user to see the drop down list. But when there are records in the gridview, I do not want the user to see this drop down list. How can I hide it when there is no data?

I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.

Working on a site where a user does a search, it takes the input from the user and then runs an SQL command to return the data in a gridview for the user to see. I also have a button where the user can see all the results from the DB (this will be taken out later but for now the DB is pretty small) This is all working fine, but the problem I am having is that when you look at the page source the gridview populates everything in tables on the page. This makes it really easy to just copy and paste and get everything from my database. How can I go about displaying the information to the user in a gridview, but hiding the table information in the html page source?

The situation: a FormView with an EditItemTemplate and an Insert Item Template. When the page is entered and a record exists in the datasource, everything is fine with the Formview in Edit mode and the Edit ItemTemplate being used. But when no record is present, the FormView uses the EmptyDataTemplate even though it was switched it to Insert mode. Here is the code used to switch modes, fired in the OnDataBound event:
protected void SetModeAndHeadings(object sender, EventArgs e)
{
if (FormView1.DataItemCount == 0)
{
FormView1.ChangeMode(FormViewMode.Insert);
}
else
{
FormView1.ChangeMode(FormViewMode.Edit);
}
etc...
}
Is the problem that it switched to Insert mode too late? What has to be done differently here to automatically switch between Edit and Insert modes?

There is user selected search criteria used to display both a FormView (Invoice header information such as ship_id, vendor, date, store, etc...) and cooresponding GridviewDetails (product details such as upc, description, unit cost, qty ordered, qty received, etc...) There is a one to many relationship between 1 invoice (formview) and many product details (gridview). I need to add the ability to insert product details to a particular invoice (ship_id is the link between the 2 tables) if an invoice currently doesn't have any. I have the emptydatatemplate programmed with dropdownlists and textboxes to capture the user entered information along with a submit button. However the insert doesn't occur.
I know the problem is how I am (incorrectly) using the findcontrol, but for the life of me I can't seem to find the correct syntax (been searching the forums for nearly a weeks implementing different syntax and testing to no avail!)
I have successfully implemented the ability to insert a new row using the footertemplate and was banking on some of that code to assist me with the insert of new details in the emptydatetemplate. Grrrrr....still not working. Below is the current version of the test page programming.
Code behind for the OnClick button in the emptydatatemplate "submit": (note: I know at least part of the problem is in how I am attempting to find the controls. Here is where I can not find a syntax that works and I have tried several dozen versions...)
[Code]....
GridviewDetails EmptyDataTemplate programming is below:
[Code]....
I've also included my entire GridViewDetails programming just in case it helps to read what it is that I am trying to do:
[Code]....
And here's the entire code behind that I have so far to make everything else function as desired:

I can't seem to get either EmptyDataTemplate or EmptyDataText of a GridView to work. I'm fetching the GridView contents in de codebehind and attaching them with using DataBind(). I've tried having them as null and as an empty List, and in both cases the text I put intoEmptyDataTemplate or EmptyDataText is not displayed. What am I doing wrong?
EDIT (Code snippet) This is my GridView:
<asp:GridView ID="grid" runat="server" EmptyDataText="EMPTY"></asp:GridView>
And I've tried these two for binding the data:
grid.DataSource = new List<object>();grid.DataBind();grid.DataSource = null;grid.DataBind();

I have a grid view (using sqldatasource & C#) which returns no rows. By design asp.net does not show header/footer. I looked at couple of sites and suggestions and found it to be too complex. Nothing was simple. The one I found was to create a empty datatable, insert rows and bind it to the gridview. But that code does notwork for me because I am using sqldatasource and using datatable gives error.I decided to just add the following to empty item template.
<EmptyDataTemplate>
<div>
<asp:Label Text="No details found." runat="server"> </asp:Label>[code]....
THe link shows up in the bottom but the event gridview_RowCommand is not fired as the grid view is not created or it does not have rows
How do I call a function on click the add new link and put all my code in there to insert possibly using a modal popup. I cannot use onclientclick because it is javascript.
