Web Forms :: Access And Set Value In TextBox Inside FormView Control
Aug 20, 2013
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))

Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...

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 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 the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. 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 checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End Sub
I've started to figure this out based on other questions I looked up on here, but all of them were in C# instead of VB, so this is as far as I got:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
End If
End Sub
So yeah I'm not sure exactly how to finish it. here's my code now:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
CheckBox checkGenEd = formview1.FindControl("checkGenEd");
Panel panelOutcome = formview1.FindControl("panelOutcome");
End If
End Sub
It's also saying that checkGenEd and panelOutcome are not declared. I changed my code to this but it still doesn't work:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound
If FormView1.CurrentMode = FormViewMode.Edit Then
Dim checkGenEd As CheckBox = FormView1.FindControl("checkGenEd")
Dim panelOutcome As Panel = FormView1.FindControl("panelOutcome")
If checkGenEd.Checked = True Then
panelOutcome.Visible = True
Else
panelOutcome.Visible = False
End If
End If
End Sub
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.

VS2008 c#, asp.net 3.5, ms sql 2008How do I validate user input in TextBox inside a FormView [Insert Mode] with MS SQL 2008 Database?* FormView #fvInsertProjectInfo* TextBox #txtProjectNameCurrently, user could insert a new project using the FormView, but will only be found out that the project is already existed when pressing the INSERT button. To make it more user friendly, I would like to check that the database does not contain a record of the project the user trying to insert (by comparing value in txtProjectName with the Projects table in the database)

How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

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 have tried to use CreateUserWizard control inside Formview to avoid manual coding. CreateUserWizard control is a member of InsertItemTemplate of FormView control, I have bounded all the input controls inside CreateUserWizard to database fields but when I click on create user button I get following exception
SQLBindParameter not used for all parameters
after getting through some links I got to know that this may be beacause of mismatch between no of ? marks with specified insert paramters.

I have a fairly simple form:
[code]....
However, once the update is finished (and I call e.Cancel = true), the LoginView control does not databind its children... so they are all blank. The FormView's viewstate is still fine, as all the rest of the controls outside of the LoginView appear fine. I even handle the FormView_DataBound event and a Trace shows that the FormView is being databound on postback.
Why then is the LoginView not keeping its ViewState/being databound? Here's a sample code snippet showing the flow:
