Forms Data Controls :: Binding CheckBoxList In FormView?
Jul 22, 2010
I have a FormView which will bind values from the database using a ID parameter from queryString. In my database, I have a field named CategoryList which can store multiple CategoryID (From Category table) in CSV format (eg: "1,3,4,5"). I'm using SQLDataSource as my datasource.
So, I want to show the selected category in CheckBoxList. Meaning that, the checkbox will be checked (on page load) if its ID is in the CategoryList. Also, I want to allow the user to check/uncheck the CheckBoxList and updates to the database in CSV format. How can i do that?

im learning webforms and asp.net in general and what i have so far is a formview that displays data being pulled from a sqldatasource, but i also want a checkboxlist that can be used to input information and display information. this checkboxlist is insode the formview. the problem im having is that my formview is calling a datasource with an specific stored procedure with one table and my checkboxlist needs to called another stored procedure that has a different table. formviews does not allow you to have tow different datasources so how can i make this possible? ill paste the front end code and the backend code so you guys can see what im trying to do.

I can insert a checkboxlist selected value as comma delimited string into the database. But I have hard time to reload it in formview edit mode. I added a hidden label to retrieve the comma delimited string and try to use checkboxlist databound event, but it doesn't work. I don't know what problem is in my code.

<asp:RadioButtonList ID="RadioButtonList2" runat="server" selectedvalue='<%# Bind("FieldNameTbl") %>' RepeatDirection= "Vertical" RepeatLayout= "Table">
<asp:listitem value="0">I</asp:listitem>
<asp:listitem value="1">T</asp:listitem>
</asp:RadioButtonList>
This is how it works for a radio button list in a formview insert template.

I have a sql-bound formview with three DDL's bound to individual SQL datasources. In edit mode, I want to set the selected value to the formview's value, and this works:
<asp:DropDownList
ID="ddl2"
runat="server"
DataSourceID="ddl2lDS"
DataValueField="Name"
SelectedValue='<%# Eval("Name") %>'
/>
But it only works when there's a match between what's in the formview's DS and the DDL's DS.
Unfortunately, there may be instances where the the formview's DS may return a null value or a value different from the DDL's datasource...and when that happens I receive a compilation error like:
'ddl2' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
What do I need to do to trap that condition before attempting to set the selected value? Do I need to set the selected value of the DDL in formview's dataBinding or dataBound event, by looping through the DDL and checking for a match first?

I have a formview bound to an entitydatsource and it is working fine. here's the scenario though
If the querystring contains a "memberID" , I have setup an object datasource to fetch the results corresponding to the memberid from the database.
I want the name and email id fields in the formview to default to these values in the objectdatasource. How can you do this?

I have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.

I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?

In an vwd2005 aspx page, I have a formview, dropdownlist and 2 sqldatasources. My markup is below
[Code]....
When the dropdownlist causes the postback, the formview does not display the data (it's there, I've double checked using query analyzer). Also, the OnIndexChanged only makes a button visible and has nothing to do with the data. What am I missing?

FormView custom data binding problem
View 7 Replies
Sep 29, 2010
Okay, here's something that I could easily do the hard way and manually wire up each form element and save it to a datatable in memory, but there has to be a more efficient way to do it.
Here's what I have:
1. A strongly typed datatable and tableadapter in a XSD name Orders
2. A formview control which currently is connected to an ODS connected to the Orders tableadapter, this makes it easy to wire up the databindings for each form field in design view
I would like to:
- bind the the formview to an instance of the strongly typed datatable, and then save the dt to a session object without interacting with the actual database
- load forms on subsequent pages from the dt in session
- ultimately save the dt info to an actual database table on the third page
I've read some solutions where a custom class is created, but to me this seems like almost as much work as wiring up the form field to the table columns manually in code.

I don't much care for the template rigmarole of the ASP.NET FormView web forms control. It seems the only way to access template defined controls is to 'capture' module level references to the wanted controls in the ItemCreated data binding event, for use in other tasks and event handlers. Ideally I would just like to be able to call set this.DataSource and call this.DataBind on a page, but only the latter is possible through inheritence, and doesn't achieve any of my normal data binding needs. What else is there besides the hairy, scary FormView control?

I have the follow form view:
<asp:FormView
DefaultMode="Edit"
ID="FormView1"
runat="server"
onitemupdating="FormView1_ItemUpdating">
<EditItemTemplate>
<asp:TextBox
ID="txtPrimerNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("PrimerNombre") %>'></asp:TextBox>
<asp:TextBox
ID="txtSegundoNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("SegundoNombre") %>'></asp:TextBox>
</EditItemTemplate>
</asp:FormView>
<asp:Button
ID="Actualizar"
runat="server"
Text="Button"
CommandName="Update"
/>
This formview is bound in this way:
protected void Page_Load(object sender,
EventArgs e)
{
Persona _persona =
new
Persona();
_persona.ObternerPersonaByUserIdApp(1);
List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona =
new
List<SILPA.AccesoDatos.Generico.PersonaIdentity>();
persona.Add(_persona.Identity);
FormView1.DataSource = persona;
FormView1.DataBind();
}
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs
e)
{
}

I have a FormView that I user for updating a record. There is a link button that when fires should perforom the updating via BLL and DAL. I am not using built-in ODS and I will not condsider using it. I have all my grids and formviews populated manuualy by calling methods that fetch the data from the database. For instance my details view is populated like this:
protected void DlMembers_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Select")
{
DlMembers.Visible = false;
lblError.Text = string.Empty;
lblError.Visible = false;
fvMemberDetail.Visible = true;
fvMemberDetail.ChangeMode(FormViewMode.Edit);
MemberBLL getMemberInfo = new MemberBLL();
int Ident = Convert.ToInt32(e.CommandArgument.ToString());
fvMemberDetail.DataSource = getMemberInfo.GetMemberByIdent(Ident);
fvMemberDetail.DataBind();
}
if (e.CommandName.ToString() == "DeleteSelected")
{
DlMembers.Visible = true;
lblError.Text = string.Empty;
lblError.Visible = false;
fvMemberDetail.Visible = false;
fvMemberDetail.ChangeMode(FormViewMode.ReadOnly);
}
What I want to do if to capature my linkbutton on click event and do this (except that the runtime never reaches this method):
protected void MemberInfoUpdating(object sender, EventArgs e)
{
TextBox id = (TextBox)fvMemberDetail.FindControl("txtIdent");
if (id.Text != string.Empty || id.Text != "")
{
TextBox txtFN = (TextBox)fvMemberDetail.FindControl("txtFN");
TextBox txtLN = (TextBox)fvMemberDetail.FindControl("txtLN");
DropDownList ddlAddress = (DropDownList)fvMemberDetail.FindControl("ddlAddress");
TextBox txtEmail = (TextBox)fvMemberDetail.FindControl("txtEmail");
TextBox txtHPhone = (TextBox)fvMemberDetail.FindControl("txtHPhone");
TextBox txtWPhone = (TextBox)fvMemberDetail.FindControl("txtWPhone");
TextBox txtMPhone = (TextBox)fvMemberDetail.FindControl("txtMPhone");
DropDownList ddlPos = (DropDownList)fvMemberDetail.FindControl("ddlPos");
DropDownList ddlIsAdmin = (DropDownList)fvMemberDetail.FindControl("ddlIsAdmin");
bool blIsAdmin = false;
if (ddlIsAdmin.SelectedValue == "True") blIsAdmin = true;
TextBox txtComments = (TextBox)fvMemberDetail.FindControl("txtComments");
MemberBLL updateMemberInfo = new MemberBLL();
bool UpdateOK = updateMemberInfo.UpdateMemberByIdent(
txtFN.Text,
txtLN.Text,
ddlAddress.SelectedValue,
txtEmail.Text,
txtHPhone.Text,
txtWPhone.Text,
txtMPhone.Text,
blIsAdmin,
txtComments.Text,
Convert.ToInt32(ddlPos.SelectedValue),
Convert.ToInt32(id.Text));
}
else
{
//Display error - no user id cannot update record
}
}
The linkbutton looks like this:
<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True"
OnClick="MemberInfoUpdating" Text="Update" />

I have a Formview binded in the code file to a generic list. Now, upon editing of a record, I wish to access the Keys and NewValues out of the FormViewUpdateEventArgs parameter of the ItemUpdating event handler method. From what I've tried and searched over the internet as of now, I've come to know that updated values are only available if the Formview is set a data source control on the markup page else they'd be null. Is this true?
Secondly, at this moment I am casting the sender object to formview and individually filling each object property by using FindControl method to find and retrieve values present in the controls. Is this the best way to do this task? As an example, this is what I am doing atm:
FormView currentForm = (FormView)sender;
ListObject.ID = new Guid(((HiddenField)(currentForm.FindControl("hdnID"))).Value);
ListObject.Name = ((TextBox)(currentForm.FindControl("txtName"))).Text;

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 a Formview that is bound to an SQL database, and in its item template I have added an image button.
That image button on selection needs to postback a primary key Value (VoucherID) to be used in a second control on the same page. In VWD I can get it to post back but I can't get it to post back with the VoucherID parameter.
I can easily get it to send a querystring parameter, but I don't want to do it this way.

I have a situation where I need to databind a string array to a CheckBoxList. The decision if each item should be checked, or not, needs to be done by using a different string array. Here's a code sample:
string[] supportedTransports = ... ;// "sms,tcp,http,direct"
string[] transports = ... ; // subset of the above, i.e. "sms,http"
// bind supportedTransports to the CheckBoxList
TransportsCheckBoxList.DataSource = supportedTransports;
TransportsCheckBoxList.DataBind();
This binds nicely, but each item is unchecked. I need to query transports, somehow, to determine the checked status. I am wondering if there is an easy way to do this with CheckBoxList or if I have to create some kind of adapter and bind to that?

I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
