Web Forms :: Lock A TextBox In A FormView?
Dec 3, 2010
I have a FormViewwith several bound textboxes whose values (text) are generated in code. The textboxes are bound to the data with Bind("<FieldName>"). Because there values are generated in code, I'd rather not let my users change their values. I have tried making them read only. However the values of the text boxes did not update when the form was updated. I tried disabling the textboxes but that grayed them out. I tried replacing the textBoxes with labels while keeping Bind("<FieldName>") but that didn't update either.
(1) Am I doing this right? (2) Is there any way to lock the value of a text box without graying the textbox?

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 need to set the value of TextBox in a FormView when the mode changes to Insert. But when I was trying to get it to work, neither one of the code blocks below worked. The value was not set, despite the TextBox being found. Furthermore, the 'test' label text wasn't being set. I know for certain that both events are firing. I had added the test label to disploay the mode or newmode of the FormView but the label wasn't being set at all.

I have a textbox within a formview that is binded to some data. The only problem is that the size keeps changing if the page is zoomed or screen size is changed.
Is there any way to set the the textbox to utilise the enitre width of a page regardless of zoom or screen size as currently on 75% zoom it remains about half way however on 100% zoom it fills the entire screen.

I trying to save clients IP address who are submitting the data on my website. I have downloaded an example and implemented. That scrip displays IP address on the webpage. I can submit this to sql table through code behind. Now I want to use same script in FormView and I am unable to bind this with the text box as it is showing an error "The name IPaddress does not exist in the current context". My code is as under :
<script runat="server">
protected void Page_Load(object sender, EventArgs e) {
string IPAdd = string.Empty;
IPAdd = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (string.IsNullOrEmpty(IPAdd))

I need to set the defaulfocus for a webpage that will be used for scanned input.
The page needs to start with focus on a textbox in a formview and remain there as each item is scanned. I have already setup the default button to update data on enter which will happen as each item is scanned. There is only one text box and the update button in the formview.

I have a webform that has a formview (fvwContract) and inside itemtemplate there is a Tabcontainer with three tabs (invoice (spanish: factura), receipt (spanish: recibo) and beneficiary (spanish: beneficiario). I have another formview inside invoice tab (fvwFactura) with many textboxes that I need to manipulate in code behind. The thing is that I can´t reference any of them like the following:
protected void DropDownList1_SelectedIndexChanged2(object sender, EventArgs e)
{
AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)fvwContract.FindControl("TabContainer1");
FormView myforma = (FormView)container.FindControl("fvwFactura");
TextBox txtdos = (TextBox)myforma.Row.FindControl("txt2");
Label lbldos = (Label)myforma.Row.FindControl("lbl1");
lbldos.Text = "sample1";
txtdos.Text = "sample2";
}
I just don't know how to reference any control inside frwContract.TabContainer1.fvwFactura

I have a formview containing an insert template. One of the fields you can insert is a multiline textbox. When i update or insert, i write the value to an SQL database. The next time i edit the record, everything shows up in the multiline textbox as it was when i inserted it. This includes the newlines(or break rules, or whatever you call it in english) i've entered.
For my itemtemplate, i want to use a label to represent this value. But when i do so, it doesn't use newlines, it just puts the text in one line.
How does the multiline textbox save these 'new lines' to the database? and how can i retrieve them when using a label?

I have a Formview where students put their information in such as name, address, etc. The text boxes are bound to my database, so once they are done, they choose to update, and my database is updated with their information. My problem is that the students often use All Caps to enter in their information.
I think I need the StrConv somehow, but I just can't seem to get this done. I've seen where it could be done with text boxes, but not when they were in a Formview using parameters.

Here my question is very simple. That what I want to do is to select a date using asp.net calender control and insert into textbox. Both the controls are in the InsertItemTemplate of the FormView.
1. Page1.aspx has a textbox and an image for calender.
2. Calendar.aspx is to select any date and with the help of session it should go back to its parent page in the text box and dispose itself.
Achievement:1. From Page1.aspx when i click Calender image, perfectly a new page Calendar.aspx opens.
2. On Calendar.aspx page, date selection is also OK.
3. Using Session, the date is perfectly transfering to next page.
Problem: 1. When I select date from Calendar.aspx it is not transfering back to Page1
in textbox.
2. Secondly when I select date from Calendar.aspx it is not disposing itself after date selection.

I am using a textbox and button to get the user input (account number), this will be used as input to a data access class object (SQL) when the button is clicked. This action should populate the Formview control. I have bound the Formview control to the SQLdatasource and configured the SQLdatasource control to the textbox.TEXT property. What am I missing? What do I need to add to button_clicked event to get all this to work? One other thing, the textbox is in a table area separate from the formview control. I have each of the templates inside of the formview control in tables. The input textbox and button are displayed but the formview control is not, all of this is in a master/detail object.

I want to preset the value of a textbox within a databound formview. Tried it within codebehind on onModeChanging and onItemInserting. Method onModeChanging was fired but the textbox.text shows not the expected text. Method onItemInserting was not fired at all.
Thought to use inlinecode like
<asp:TextBox ID="txt_CREATOR" runat="server" CssClass="txtTask" Text="<%=giSessionHandling.UserName %>"/>
in the aspx but don't know how to ...
<asp:FormView
ID="frmViewDetail"
runat="server"
DataSourceID="dsrcDetail"

I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

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 created a formview that I am using for data input (DefaultMode=Insert)
One of the objects I have is a text box (see below)
[code]....
When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?

I have an email contact form that I have successfully populated the account users Username and email address into text boxes
I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
The thing I am having an incredibly hard time figuring out is how to populate a single textbox with the data from any of those fields. or the whole control as a single summary.
Just for starters I am actually an IT Manager and NOT a coder so this is entirely a hack job if there ever was one...
