Forms Data Controls :: FormView Keys Count Is Always Coming Zero?
Aug 11, 2010
I have a very simple formview which opens fine with FirstName and LastName as the values in it. But when I click on the update button and inside the onitemupdating method the Keys count is always coming Zero. I have failed to understand why?
Here is my simple Forview:
<asp:FormView ID="_fvSuitableApplicant" runat="server" DefaultMode="Edit" Width="100%"
OnItemUpdated="TempApplUpdated" onitemupdating="TempApp_ItemUpdating" DataKeyNames="OpportunityKey">
<EditItemTemplate>

I 'm trying to use a gv with a modal formview to edit the row details
my first problem is: i can't get the Gv data keys there are actually two but i im trying to go one at a time. the data keys will be 1=rideid & 2=rideleg ... the combination of these two fields make all rows unique.
Secondly: after the row has been edited i need to change the data source so it can be saved in a second table.
these are the errors i'm getting with the code below
Error 65 The best overloaded method match for 'System.Web.UI.WebControls.ParameterCollection.Add(string, string)' has some invalid arguments
Error 66 Argument '2': cannot convert from 'object' to 'string'

I have a DataGrid that I need to be able to use to delete records form a file
[Code]....
[Code]....
I use
((TextBox)GridMenuOptions.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
To access the data in the Grid for updating, but it doesn't work for deleting
I can use
string id = GridMenuOptions.DataKeys[e.RowIndex].Value.ToString();
but that only returns the first key.
How do I access the rest of the keys?

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;

In the GridView_RowUpdated event the e.OldValues.count <> e.NewValues.Count. 1 out of 5 columns has been converted to a template field.

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

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 gridview with a select button. There are 181 records in the gridview all coming from the same database table. When I select the first 5 rows the details view comes up, but after that it doesn't show... The information that it is pulling is the same for the first 5 rows as the other 176 rows. Why won't it show the detailsview?!

I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?

My current project has many peripheral systems and many different environments (testing, integration, development etc). As expected, we're using .config files to dynamically manage everything.
Instead of updating each relavant key when deploying to an environment, I was hoping there was a way to change 1 key only. Such as:
<add key="Environment" value="Development"/>
<add key="WebServiceLocation" value="http://<<Environment>>/text.asmx"/>
I've done some searching and haven't come up with an elegant solution. I'm aware that .config files can make use of system variables, but this seems like a bit of a high wire act.

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.

I have a form which has some dropdownlists (ListItems "Yes" "No"). I use my form to Enter data & submit to database and use same form to Edit aswell. Like I redirect to this form from another page with a QueryString. If there is a QueryString then SELECT * FROM Table WHERE ID = QueryString's value & fill all the controls in the form like
[URL]
I have certain things to do when DropDownList.SelectedValue = "Yes" so I can use SelectedIndexChanged event handler & AutoPostBack="true" when submitting form for the first time. Now when I edit the information(Data filled from table as stated above). How can i automatically fire all events like DropDownlist SelectedIndexChanged in the page_Load iteslef so that all the things that are supposed to be done when DropDownList.SelectedValue = "Yes". I'm posting my test code for reference to explain what I'm trying to do. This is just the Idea. I have something else to deal with if i can get this stright. I need to dynamically add controls based on the values of DropDownList. please suggest some thing guys.
