Forms Data Controls :: Get FormView To Use InsertItemTemplate Instead Of EmptyDataTemplate?

Jul 30, 2010

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?

Forms Data Controls :: FormView.EmptyDataTemplate Hide Controls

Jan 21, 2010

I would like to hide several checkboxes if the FormView EmptyData Template is visible. How would I do that? My EmptyData Template has a message to the visitor that states "Sorry no records found", so when it is displayed I would like for my CheckBoxes to be hidden. Here is the code behind that I've started with and of course it doesn't work.

If FormView2.EmptyDataTemplate IsNot Nothing Then
CheckBox1.Visible = False
CheckBox2.Visible = False
CheckBox3.Visible = False
CheckBox4.Visible = False
CheckBox5.Visible = False
End If

Forms Data Controls :: Load FormView Data From Backend Using Dataset

Sep 19, 2010

I was searching for my problem for last couple of days. But coudn't find a better solution. So here I go again. What I did which worked great: I was going to a asp page with pre populated Dataset (dataset is already loaded with data), for a GridView. If I do the following .... the GridView shows all the data (with the fields Dataset comes with).

[Code]....

Now what I am trying to do: I am trying to do exact same thing but instead of using GridView, I would like to display data in a FormView. So now I tried to do this

[Code]....

PROBLEM: I can see the FormView Header with text "Test Dataset With FormView" and below the Header it displays the page numbers. I know that I have 3 data in the data set and I can see 3 page link in the FormView. But PROBLEM is it doesn't display any Field / Data. Not sure why it is doing this

Note that I wouldn't know what field to display in the FormView. Whatever I have in the Dataset I need to display. Is there any work around to accomlish my work (maybe by not using a FormView, but other conrol ?). My original goal is to Display Data in a Form View Format (One data at a time

Forms Data Controls :: FormView Data Source Calling Select Function On Page Load

Mar 24, 2010

I have a GridView and a FormView on the same page. They both have separate DataSources. This is a simple Master Details configuration, when a someone clicks on the Select link in the GridView, the FormView brings up the Details data. But for some reason the FormView's DataSource is trying to retrieve data when I load the page. This is causing an error because no ID is passed from the GridView.

Forms Data Controls :: DropDownList Bind Error - Force Order Of FormView And Child Controls Load?

May 4, 2010

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:

<asp:FormView
ID="fvTicketUpdate"
runat="server"

[code]...

The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:

public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)

[code]...

The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:

Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.

Web Forms :: How To Load Image Before Completion Of Code Behind In PageLoad

Dec 27, 2010

Forms Data Controls :: Using GridView's EmptyDataTemplate To Insert New Row?

Jul 6, 2010

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...)

GridviewDetails EmptyDataTemplate programming is below:

I've also included my entire GridViewDetails programming just in case it helps to read what it is that I am trying to do:

Forms Data Controls :: FormView/GridView Back And Forth Causes "Failed To Load Viewstate"?

Jun 12, 2010

I have a FormView and a GridView connected to the same datasource inside of a MultiView where one view is for the grid and the other for the form. The GridView has selection enabled and when the user selects a record in the GridView I make sure that the same record is selected in the FormView.mv.ActiveViewIndex = vIndexForm; // causes the MultiView to change views from the grid to the form
fv.PageIndex = gv.SelectedIndex + (gv.PageIndex * gv.PageSize); // causes the FormView to use the same selected record as the GridView

This should cause a PageIndexChanged event (it doesn't), so I called by event handler explicitly. In the event handler I change the mode to FormViewMode.Edit. This should cause a ModeChanged event (again it doesn't), so again I called it explicitly.Finally in the ModeChanged event I get the DataItem for the FormView so that I can update some special fields that require some special formatting, however fv.DataItem is null which means I can't do any special formatting. At this point the FormView shows and the regular fields are fine. If I now hit the Cancel button the FormView fires the ChangedMode event at which point I changed the MultiView's ActiveViewIndex back to the view with the grid. The grid displayes just fine, but if I do a select of a row within the GridView again I get the "Failed to load viewstate" error.I can only assume that I'm either doing something in the wrong order or at the wrong time and it's tripping me up.

Forms Data Controls :: How To Navigate From EmptyDataTemplate To Other Templates In ListView

Oct 1, 2010

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?

Forms Data Controls :: EmptyDataTemplate And EmptyDataText Not Working In GridView

Jun 9, 2010

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();

Forms Data Controls :: GridView: Adding Links To EmptyDataTemplate?

Aug 17, 2010

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.

Forms Data Controls :: Getting A Gridview To Generate Thead And Tbody While An Emptydatatemplate Is Being Used?

Dec 17, 2010

I have a curious issue,I am using a combination of asp.net controls with Jquery and am using the JQuery plug called datatables. Instead of applying this to a html table, I applied it to an asp.net gridview. To get it to work, I had to add the thead and tbody tags to the grid like so in the c#:

tablename.UseAccessibleHeader = true;tablename.HeaderRow.TableSection = TableRowSection.TableHeader;

The issue is, is when data is filtered in the table, often there are no results and the emptydatatemplate is used. When this occurs the thead and tbody tags are not in the source outputted by the browser, and an occur occurs and the jquery does not function. Error: 'asSorting' is null or not an objectDoes anyone know a solution? I need to use both the gridview and the jquery datatables ideally.

Forms Data Controls :: Can Do Javascript Validation On Gridview Emptydatatemplate Controls

Sep 22, 2010

The requirement is like the users should enter data and should be able to see the entered data before final save. So, I've taken a gridview and binded it to a temptable which will don't have any data initially, so on the first page load the datasource will be empty and the emptydatatemplate will be shown to the user. On this EmptyDataTemplate I've prepared a dataentry screen where the user can give the information and can save the data. After saving the data the data will go to the temptable and the gridview will get populated with the data the user has entered. For next go, the user can enter records through the gridview footer row. In this way I'm doing my things.

Now I haven't done the validation yet, I wanted to do a validation of the user input on gridview emptydatatemplate and gridview footer as well. In order to do that I've created one Button object on RowDataBound and assigned the gridview emptydatatemplate save button against it and also binded one javascript function with this button like below.

[Code]....

The javascript is working fine and returning boolean values based on the validation done.

But the problem is after I did this validations the RowCommand event of my gridview is not firing. I'm inserting this records on this event only based on the commandname of the button. But if I remove this javascript validation everything works fine for me.

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?
