Forms Data Controls :: How To Pass A FormView Value To Another Datasource On The Same Page
Apr 19, 2010
I am trying to create a page which uses formview to display an existing record
I want to add a gridview to the same page which will display records related to one of the fields in the formview.
In the select criteria for the datasource of the Gridview how do I reference the field from the formview?
for example something like this: Select * from table2 where table2.IDinstance =formview1.editbox1.tostring

I have created a simple dataset with my ObjcetDataSource to my SQL table named Invoices and a new FormView. My form inserts are working 100% correctly, however after some testing i noticed the insert happens again if i hit the refresh button on my browser after an initial insert. I am currently submitting the form back to itself with a success/fail message returned on the page so that the user can keep inserting more records if they choose. This is done in my Inserted behaviour.
In my ObjectDataSource_Inserting code i am setting the values of a date prior to my insert. How do i stop a second INSERT from happening when the user refreshes the browser? I thought it was what IsPostBack was used for? Here is my code:

I have a Formview to add new record to a sqlsource. This Form in Edit mode has New button for adding new records so this is perfect.
However in some case, this source could be refreshed and all records deleted and then ready to accept new records. However, I found once there is no record returned from sqlsdatasource, this Formview does not display at all, including that New button and so the whole page is blank.
how to make sure the Formview display that New button even when their is not yet record from the database.

Does anyone have an example of a formview and a gridview master detail relationship in c# ?
The gridview datasource is a datatable and the gridview is inside of the edititemtemplate of the formview.
In what event of the formview do you bind the gridview datasource?

I have a master page with a textbox that I want to use for a search, and display the results on the content page.
I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.
The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.
How do I set this master page search box as the parameter for my datasource?

I have a formview with both edititem template and item template as following:
<asp:FormView ID="PFTFormView" runat="server"
DataKeyNames="PFTId"
EnableModelValidation="True" Width="90%"
OnItemUpdating="PFTFormView_ItemUpdating"
onmodechanging="PFTFormView_ModeChanging" >
<EditItemTemplate>
<table>
<tr><td class="style1">PFTId</td><td class="style3"><asp:Label ID="lblPFTId" runat="server" Text='<%# Eval("PFTId") %>' /></td></tr>
<tr><td class="style1">Last Name</td><td><asp:TextBox ID="txtPFTLastName" runat="server" Text='<%# Bind("PFTLastName") %>' Width="200px" /></td></tr>
<tr><td class="style1">First Name</td><td><asp:TextBox ID="txtPFTFirstName" runat="server" Text='<%# Bind("PFTFirstName") %>' Width="200px" /></td></tr>
<tr><td class="style1">Home</td><td><asp:TextBox ID="txtPFTHome" runat="server" Text='<%# Bind("PFTHome") %>' Width="200px" /></td></tr>
</table><br />
<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True"
CommandName="Update" Text="Update" />
<asp:LinkButton ID="UpdateCancelButton" runat="server"
CausesValidation="False" CommandName="Cancel" Text="Cancel" />
</EditItemTemplate>
<ItemTemplate>
<table>
<tr><td>PFTId</td><td><asp:Label ID="lblPFTId" runat="server" Text='<%# Eval("PFTId") %>' /></td></tr>
<tr><td>Last Name</td><td> <asp:Label ID="lblPFTLastName" runat="server" Text='<%# Bind("PFTLastName") %>' /></td></tr>
<tr><td>First Name</td><td><asp:Label ID="lblPFTFirstName" runat="server" Text='<%# Bind("PFTFirstName") %>' /></td></tr>
<tr><td>Home</td><td> <asp:Label ID="lblPFTHome" runat="server" Text='<%# Bind("PFTHome") %>' /></td></tr>
</table><br />
<asp:LinkButton ID="EditButton" runat="server" CausesValidation="False"
CommandName="Edit" Text="Edit" />
</ItemTemplate>
</asp:FormView>
on my code behind, I have:
Sub PFTFormView_ItemUpdating(ByVal sender As Object, ByVal e As FormViewUpdateEventArgs)
Dim PFTObj As New PFT
Dim PFTDST As New Data.DataSet
Dim newPFTLastName As String = DirectCast(PFTFormView.FindControl("txtPFTLastName"), TextBox).Text
Dim newPFTFirstName As String = DirectCast(PFTFormView.FindControl("txtPFTFirstName"), TextBox).Text
PFTObj.PFTLastName = newPFTLastName
PFTObj.PFTFirstName = newPFTFirstName
PFTObj.PFTHome = DirectCast(PFTFormView.FindControl("txtPFTHome"), TextBox).Text
If PFTObj.UpdatePFT(Session("PFTId")) Then
Me.lblErrorMessage.Text = "PFT Update Successfully"
Else
'
Me.lblErrorMessage.Text = "PFT Update UnSuccessfully"
End If
PFTDST = Nothing
PFTObj = Nothing
end sub
The problem is:
PFTObj.PFTLastName = newPFTLastName
PFTObj.PFTFirstName = newPFTFirstName
PFTObj.PFTHome = DirectCast(PFTFormView.FindControl("txtPFTHome"), TextBox).Text
are not returning the updated value from the form.

In my webpage I have a Formview bounded by sqldatasource. I can perfectly Update data from it. In the same page I have a gridview bounded by some other sqldatasource. I have to give user new record option from gridview.
I know that there is no default property to insert new record with the help of gridview until we provide some other way by coding but I don't want to do that.
Therefore I have taken a textbox with the validation field and a button outside the gridview to insert new record into gridview and refresh it.
I don't want to allow user to add empty text using textbox thatswhy I have validated that textbox.
Problem:
If user has the scenario to update only the Formview then he cannot because there is a validation there with the textbox.
If I remove the validation then user is able to update FormView perfectly but may add empty text from the textbox.
if the user allowed to update FormView and to add data with the help of textbox and gridview get refresh. If user can do only one task also either to update FormView or to add data from textbox to refresh gridview.
The task is most important for me and I have only 12 hours to complete this task or you can say the time limit is going to expire.

I have 4 buttons and 1 FormView.
The FormView has AllowPaging = true.
When you click on a button SQLDataSource1 is bind to the FormView.
So you always have 4 pages.
The data in the FormView has an ID.
When you click Button1 you know you want to see the data with ID=4.
When you click Button2 you know you want to see the data with ID=1.
When you click Button3 you know you want to see the data with ID=2.
When you click Button4 you know you want to see the data with ID=3.
What I want is: when you click on a Button you get the page in the FormView
that corresponds with the ID of the data.
So page 1 isn't ID=1!
What do I have to program to get this working?

I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

I have 2 dropdownlist(ddlCategoryFooter and ddlItemCodeFooter)inside my gridview. I want to set ddlItemCodeFooter 's datasource to my getItemList(decimal categoryID) method. The selecteditem of ddlCategoryFooter will serve as the paramter which will be passed to my getItemList Method. Basically,ddlItemCodeFooter is dependent on ddlCategoryFooter's selectedItem.
I know it can be done in code behind approach but i prefer to place it in my asp page.
This i what i want to acheive:
DataSource ='<%# getItemList(Convert.ToDecimcal(ddlCategoryFooter.seletectItem))%>'/>
Source code for my Gridview:

I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?

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.

So, I'm trying to use form view in insert mode on a dedicated aspx page. So when a user clicks "Add New" from the main GridView page, it will take the user to an Insert.aspx page that will be in Insert mode ready to collect information.
Here's what I have so far, and all I get is a blank page when I try to run it.

I have a FormView at the very bottom of the page in insert/edit mode. When I click insert/update button, the whole page reload and the pointer does not keep within the Formview but go to the very top of the page far away from the desired FormView.
What can I do here to prevent cursor going outside the Formview ? Is it I can use update panel ? What and where I should use the tags ? Or there are other better way ?
