I am trying to display data in a formview based on the value selected from the drop down list. FormView does not respond or display any data.
<b>Select a vendor:</b>
<asp:DropDownList ID="vendorDropDownList" runat="server"
DataSourceId="SqlDataSource1"
AutoPostBack="True" DataTextField="CO_Vendor_Name"
[Code]....
I have a FormView which is used to insert a record into a database. Outside of this formview i have a drop down list, I want to grab the value from that drop down list and set one of the text fields within the formview to it's currently selected value. I've tried the following code, but the dynamic categorytextbox line is what seems to not be working.
[Code]....
I have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.
I have a table Person (in my database) which has fields like PersonID, PersonName, PersonSurname, etc. What I'd like to do is to bind the PersonName + PersonSurname (e.g. Mark Black) as values for displaying the data in drop down list and PersonID as the data identifier.
As I'm still new with Entity Framework I'm not sure how to manage to do it.
I have an XML file structured as follows:
<Levels>
<Level Code="T" Text="Test">
<SubLevels>
<SubLevel Type="9" Text="Nine"/> [code]....
What I want is two drop down lists, one linked to /Levels/Level and one to the SubLevels for the selected level. Currently, I have the main one bound as follows:
<asp:XmlDataSource ID="XmlLevelInfo" runat="server" DataFile="~/Levels.xml">
</asp:XmlDataSource>
<asp:DropDownList ID="cboLevelFilter" runat="server"
DataSourceID="XmlLevelInfo" DataTextField="Text" DataValueField="Code">
</asp:DropDownList>
This works fine, but I can't work out how to link the Sub Levels to the second drop down list. Is this possible using data binding?
I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?
I keep getting this error and i just can't figure it out:
The ViewData item that has the key 'CampaignId' is of type 'System.Int32' but must be of type 'IEnumerable<SelectListItem>'.
My Controller:
//show empty form
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Index(int? CampaignId)
[Code]....
I do need to have "CampaignId" in there because I'm populating some "partial views' based on this "CampaignId" that is selected (drop down)
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 have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.

This is how it works for a radio button list in a formview insert template.
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?
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 want to bind an object to a form view.

Now, is it possible to generate a new object on update, without getting and reading each textbox with findcontrol?
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 select a item from gridView and trying to show/update/delete in From view. In Form View I am using the dropdownlist filling it in Code behind. Then i bound the list. But the problem is it is not showing the slected value. Here is the code

AutoGenerateColumns="False"
Width="525px" PageSize="20" DataKeyNames="intPKCountry_DetailID" [code]....
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 RepliesOkay, 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.
when i am using dropdownlistin asp.net when i amselect the value from the list it cannot that the selected value but it can take only the first value of list.
How can i select the value in the dropdownlist.
I have a gridview with a drop down list. When I do the update I try to get the value from the drop down list, but I get an error saying that the drop down list control 'ddlType' can't be found.
Here's the code.

In this code you can see the select statement that the customers are selected for display to the user. Order by is at least being used to disply in name order. but this example here is one of several similar dropdowns. I would like that if they picked one customer then the next view show should be the same customer

I've built my own CMS using vb. It displays the pagetitle, summary and body from a database, depending upon what parameters are passed in the url.
Some pages require a drop down list where users can select a document from a list.
Is there a way to add this to the page?
something like:
