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 placed one FormView and one GridView conrtrols on the same page with one linqdatasource that is connected to both controls via their DataSourceID properties. While the GridView works without any problem (on updating) the FormView doesn't update the record.I traced the FormView events and found that in FormView1_ItemUpdating the argument e.NewVaues.Count = 0 as well as e.OldVaues. Count (also zero). Getting items from e.NewValues[index] or [key] causes an obvious exception. However, all the bound contolsn this wa

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

View 6 RepliesI have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

The bindClientDropDownList, by the way, does not call SearchResultsGridView.DataBind() on its own, so that can be ruled out.
I have a web page with a nested grid. I bind the nested grid via the outer Gridviews RowDatabound. The problem I'm having is when a user click on a CommandField in the nested child grid the Page_Load event is fireing twice and reloading the grids, making it appear that the nest grid collapsed. I have tried using "If Not Page.IsPostBack" but because the page posts back twice the IsPostBack is false until the second time the Page_Load event fires.
Here is my Page_Load routine
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

View 5 RepliesI have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?

View 1 RepliesI'm using VWD 2008 and using an SQL database with a simple web app.
I've created a SQL query that pulls data from several tables. When I execute the query in
the query builder tester, it executes OK. I'm binding the DetailsView to an ObjectSource / DataSet / TableAdapter Querry with a variable that is bound to a listbox control.
Again, the query runs fine in the query builder.
When the detailsview or gridview gets built on the page it only displays columns from one database yet it executes ok within the query builder.
I can see the generated code for the detailsview does not create fields for every field returned by the sql query ?
I have one more time a problem with a DetailsView..I would like to fill a TextBox (or Label) with a function in my DetailsView and on the Update getting value contained in this control.

I have a set of 4 buttons which part of a gridview template and I load the gridview on page_load. The datasource for the gridview comes via my controller as I am using Microsoft's Model View Controller design pattern. I set 4 public properties for each of the 4 buttons, which I can access in my controller class/method. However, when I call the method for the gridview, which sets the datasource for it on page_load, I get an error message when I try to set the enable to false. It says "Object not set to instance of object". The objective I am trying to do here is a check on a returned value, which I can achieve, and based on the return of the value that is returned, to either set the button enable to true or to false.
Unfortunately, I am getting this Object not set to instance of object error message, and I do not know how to resolve it.
I have discovered something strange when using a ListView. I have a listview contained inside an uodate panel and everything works OK until I edit the editItemTemplate to use a LinkButton instead of a Button.When i use a LinkButton then the Page_Load event is fired.
