I am trying to get the value out of an ASP.Net form view but keep hitting errors. My code is as below which currently gives a

error.
I searched and it was suggested to use

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

View 3 Replies Can a query output made in MS ACCESS be accessed as a database in Visual Studio 2008?
I have a Parent and Child Table in MS Access with a one-to-many relationship. I created a query in Access that would produce a result table and I want the contents of this Query to be displayed in a Data Grid in Visual Studio 2008.
I am trying to do dependent dropdown in a formview. I am getting this error when I select the DDL1. I ma using VS2008 and with code behind in VB.
[code]....
Below is a line I have in my ItemTemplate of a FormView. The value in the table is null rather than true/false. Is there any way I can set the default for this to be false if it is null? Or can I do this in my stored procedure in the Select statement to return false if null?
Code:
<asp:CheckBox ID="chkCharges" runat="server" Checked='<%# Bind("MCOverrideCharges") %>'
Text="Yes" Enabled = "False" />
I have a dropdownlist in my eidtItemTemplate of my formview which gets displayed in a modalpopup.
I try to get the ddl object like this:
Code:
Dim rateddl As DropDownList = CType(Me.fvTimeSheetDetail.FindControl("ddlRateType"), DropDownList)
but I get nothing. weirdly I can find a textbox like this:
Code:
CType(Me.fvTimeSheetDetail.FindControl("txtNewTSTimestamp"), TextBox).Text
howcome the ddl doesn't get detected? what am I doing wrong? the ddl is definitely there and it gets populated
I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
In FormView (insert) I have a number of textboxes into which number will be inputted. I need all these textboxes to add up and display the total in a Label which I can then insert into the database with all the individual values. I expected this to be a simple thing... Then it appears that the best way to do this is to use javascript, which I have never used! SO this is my attempt which is a combination of things I found on the net, In the head (Clientapp is the name of my form)
<script type="text/javascript" language="javascript">
function Add1(Clientapp) {
var a, b, c;
a = document.Clientapp.BondRepaymentTextBox.Value;
b = document.Clientapp.PropertyRentalTextBox.Value;
c = eval(a) + eval(b);
document.Clientapp.ceTotalTextBox.Value = c;
}
</script>
Code behind on Page Load
PropertyRentalTextBox.Attributes["onchange"] = "javascript: Changed( this );";
I'm working in a web application and my page is using a databound formview control. When i first enter the page via my code, I am unable to retreive a value from any of my controls -e.g. when i debug, i see that tbDate.text has no value (see code below). How can I retreive the values from the controls on my page e.g text boxes?
Code:
if (!this.IsPostBack)
{
TextBox tbDate = (TextBox)FormView1.Row.Cells[0].FindControl("txtDate");
}
I have a formview where DefaultMode="Insert". Underneath, I have a gridview that displays the information from the inserts. Is there a way to update the information as well as insert? Maybe there is a better way to do what I'm trying to do.

View 2 RepliesI have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End Sub
I've started to figure this out based on other questions I looked up on here, but all of them were in C# instead of VB, so this is as far as I got:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
End If
End Sub
So yeah I'm not sure exactly how to finish it. here's my code now:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
CheckBox checkGenEd = formview1.FindControl("checkGenEd");
Panel panelOutcome = formview1.FindControl("panelOutcome");
End If
End Sub
It's also saying that checkGenEd and panelOutcome are not declared. I changed my code to this but it still doesn't work:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
Dim checkGenEd As CheckBox = FormView1.FindControl("checkGenEd")
Dim panelOutcome As Panel = FormView1.FindControl("panelOutcome")
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End If
End Sub
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.
I have a formview on my aspx page containing various controls arranged using table. There is a DDL "cboClients" which i need to enable or disabled depending upon role within Edit mode.
The problem here is that i am not able to get that control using FindControl() method.
I have tried following code -
DropDownList ddl = null;
if (FormView1.Row != null)
{
ddl = (DropDownList)FormView1.Row.FindControl("cboClients");
ddl.Enabled=false;
}
Even I ave used the DataBound event of the same control -
protected void cboClients_DataBound(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Edit)
{
if ((Session["RoleName"].ToString().Equals("Clients")) || (Session["RoleName"].ToString().Equals("Suppliers")))
{
DropDownList ddl = (DropDownList)sender;
ddl.Enabled = false;
}
}
}
But this databound event occurs only once, but not when formview mode is changed.
I'm using an access database that has an AutoNumber field as the primary key. After adding a record I'd like to retrieve the ID for the record that was just entered, however, I'm not able to figure out how to do this in ASP.NET using standard AccesDataSource and FormView functionality. My goal is to retrieve the ID so that I can then use it to add an additional record in a child / sub table.
I could do it strictly using vb.net and forget about using the InsertCommand for the AccessDataSource and it's built in functionality. However, that would require a complete rewrite of some other items, accomplish this using the standard AccesDataSource functionality.
Below is a sample of something I've tried to do using "Direction='Output'" on one of the ID field for one of Insert paramaters (source: http://www.4guysfromrolla.com/articles/050207-1.aspx). The plan was to then caputre that "output" using the my "_OnInserted" sub procedue. However, apparantly I'm not able to use this with AccessDataSource. Did some research and saw that I'd have to switch to SqlDataSource which I'd rather not do cause all other pages use AccessDataSource and I'm having problems defining my connection string with it.

I have 2 sessions I need to populate a formview textbox value on Insert, session1 is set on pageload, session2 is set after a button has been clicked.
The button is outside of formview.
I have:
page load
TextBox txtTodayDate = (TextBox)(FormView1.FindControl("txtTodayDate"));
The new values entered by a user are lost when a error occurs.
I tried to solve this by catching the error in the item updated event as per the code below
[Code]....
however the data in the form gets set back to the original values.
It seams as though the object data source is rebinding the form. How can i determine if this is the case? Is there a way to stop the datasource from rebining?
I have a web app I'm creating and a form that has a formview control on it. The form's default is set to insert and when the user enters data and clicks save, the data gets saved to the database; only problem is that the form then clears all the data out of the controls.
Upon saving after updating or inserting, I'd like to set the form mode to edit and also have it retain the values they input into the form. I've tried a few things and have not had any luck.
e.g.
Code:
Protected Sub frmCustomerInformation_ItemInserted(sender As Object, e As FormViewInsertedEventArgs)
' Make sure record inserted properly.
If e.Exception Is Nothing Then
If e.AffectedRows > 0 Then
litMessage.Text = "Customer Information saved."
'GETTING THE NEW quoteCustomerInformationId FROM THE SAVED RECORD AND PLACING IT INTO A SESSION VAR.
[Code] ....
What mode does the formview control have by default after it executes the ItemInserted method? Also, what is the prper way to do this?
I am somewhat new to ASP.Net and the interesting ways to build forms that edit data. I am working on a FormView and have come to a hurdle that I can't seem to figure out how to get past.
This link will open the form and a dummy record where ID=2. [URL] ....
The ID is the variable to open a specific record. That's pretty obvious. Clicking the Edit button switches the FormView from ItemTemplate to EditItemTemplate. My problem is that after changing some values then clicking Update, the record is not updated.
I need to have the record updated and return to the ItemTemplate view. I believe there are issues with the fmvData_ItemUpdating and fmvData_ItemUpdated functions. I am not sure what has to go in there.
I also want the Inspection Date field to be formatted to mm/dd/yyyy when switching to the EditItemTemplate.
My TableAdapters are creating using the App_Code/DataSet.xsd method.
I am using Eval("fieldname") in the ItemTemplate for values and Bind("fieldname") in the EditItem template.
