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 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 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.
Is it possible to make a datafiled of a detailsview inti a dropdownlist bound to a data source?
View 6 RepliesI'm trying to get a drop down list to select a field from a table.
Below is the code for my existing datagrid. I need the maintenance column on the end to be a drop down box fetching values from a datasource. I can sort the datasource bit myself i think

I want to get a additional information (Other than DataTextField, DataValueField) in a drop-down list for each record.
how i can get this functionality?
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 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 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.
View 2 RepliesI have a dropdownlist that is bound to an objectDataSource and the dropdownlist is populated with dates, from records obtained in the database. But I need to have the default value of the dropdownlist as text saying PLEASE SELECT, however the populated list are dates.I tried adding appendbounditems to true and manually adding a list item as PLEASE SELECT but it says it is not of date type.Is there any way I can have a dropdownlist with the first one text saying PLEASE SELECT, and the remaining collection of dates obtained from the database (objectdatasource / sql query)?
View 14 RepliesI am trying to get the required field validator to work. I have given it an initial value of the first index value in the dropdown list. I is just not working. Will my contrrols residing on a View of a Multiview control effect anything. I am using all drop down lists?
View 2 RepliesI'm using an ASP.net 3.5 FormView. I wanted to add an unbound text box with the ID="tbxEditFormMode" and set it to "EDIT" when a user selects an existing record from a dropdown list control. Here is my code
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
Dim tbxFormMode As TextBox = FormView1.FindControl("tbxEditFormMode")
tbxFormMode.Text = "Update"

When I run it I get the following error message.
Object reference not set to an instance of an object

I now can reference a field in the formview, but, assigning it a value is fighting me.
I want to assign the UserName field in the formview with the login name from the Master (HttpContext.Current.User.Identity.Name).
(A) I tried the likes of: FormView1.FindControl("UserName").DefaultValue = username but of course that doesn't work.
(B) Alternatively, I tried to edit the SQL so that I passed it the HttpContext.Current.User.Identity.Name but didn't have any luck.
InsertCommand="INSERT INTO [TechUserName] ([CertName], [CertLevel], [CertLast], [CertFreq], [CertDue]) VALUES (@temp1, @CertLevel, @CertLast, @CertFreq, @CertDue)"
temp1.text=(HttpContext.Current.User.Identity.Name)

I have created a formview with 4 dynamic controls fields that LINQ to a database.
rentfoodutilitytotal
There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'totalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.
I'm used to Dreamweaver where this is possible. I find it hard to believe that I would need to use a 1 column gridView control.
Is there a way to drag one field from the db Explorer window onto my page and NOT get a grid view?
Or alternatively, I used to be able to put something like this in ASP classic (years ago!) <%= Eval("User") %>
I aggressively googled around, but could not find the information I am looking for. I know how to populate a dropdownlist using my view model andHtml.DropDownListFor helper method.
Suppose the drop down list contains U.S. stateId and stateName key value pairs. Suppose my ViewModel looks like
public class MyViewModel
{
public IList<State> States {get; set;}
public int SelectedStateId {get; set; }

Do I have to change my implementation of my view model? In any case, how to get the selected item text of the drop down list?
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
<
order by customername
"
asp:SqlDataSource
ID="Customers"
runat="server"
ConnectionString="<%$
ConnectionStrings:SecurityDB_20101025ConnectionString %>"
SelectCommand="SELECT
* FROM [Customers] WHERE ([CustomerId] = ISNULL(@CustomerId, '') OR @IsSuperAdmin = 1 )

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.

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...
here is my aspx code

Using C# and SQL as the database.I have a page with a gridview and some text boxes and drop down list boxes. A user selects a record from the grid view I query the database and fill the text boxes and drop down list boxes.
Some fields get updated periodincally thus there is no data in those fields in the database until some time.
A strange thing happens.When filling data some text boxes gets a one tab spacing .
