Forms Data Controls :: Populate A Textbox With The Contents Of A Formview (or Even A Single Field)?
Jun 24, 2010
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...
I have a listview that has been constructed using tables. I have set the DataKeyNames="SomeTextField" among others. This column is currently not visible in the ListView.
I'd like to populate a textbox on the click of any listview record with the contents "SomeTextField" column.
I have a gridview that had a field called "GenericNameHepDrug" within the row. It's not the key field. I have an insert button that opens a formview in insertmode. How can I get the selected value of generichepdrug into the formview that opens when the button is clicked? I am using VB.NET 2.0.
here is some code from the source:

Here is what I tried to do in the code nehind of the button3_click:

CLearly I am lost. I have been working with ASP.NET VB for 2 months. I'm in over my head with figuring this one out - I've been at it for days.
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 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 am simply trying to get a querystring value and pass it to a textbox in a formview with the default view set to edit mode.
Protected Sub fv_Detach_Engine_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles fv_Detach_Engine.DataBound If fv_Detach_Engine.CurrentMode = FormViewMode.Edit Then Dim tbx_IDProfileAccount As TextBox = TryCast(fv_Detach_Engine.FindControl("tbx_IDProfileAccount"), TextBox) If tbx_IDProfileAccount Is Nothing Then tbx_IDProfileAccount.Text = Request.QueryString("IDProfileAccount") End If End If End Sub
I would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
I have a column in a table that contains a message and I want this message to be displayed in a label. Here is my code which currently doesn't populate the label.
Protected conString As String = ConfigurationManager.AppSettings("sqldirectory") Dim cnn As New SqlConnection(conString) Dim cmd As New SqlCommand("select message from [database].[dbo].[table]") Dim dr As SqlDataReader Try cnn.Open() dr = cmd.ExecuteReader() lblMsg.Text = dr(0).ToString Catch ex As Exception dr = Nothing Finally cnn.Close() End Try
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.
Im trying to populate my formview from a dataview in the codebehind and the order in which things are happening is causing it to fail.my formview itemtemplate is setup with some eval("fields") which is initially not populated (nothing bound to it) and the page loads ok. i think click on my graph which generates a query and populates a dataview.i then assign that dataview to the formview and run the bind.what happens when i actually run the app is that it says no data is bound to it.i set the debugged to stop at the point where my DV is assigned to my FV and the FV shows a data item count of 1 (as expected) if i keep stepping it puts me in to the eval statements on the aspx page says the data isnt bound. the error i get is
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have a parts table (ID, PartName, Category). I have an Engine table that has 10 columns to specify the 10 main parts that comprise the engine (EngineID, PartA_ID, PartB_ID, PartC_ID...).
I want to make only one trip to the DB to pull all the rows, then filter by category for each PartA, PartB, etc ddl. how to do this?
I have a ddl inside the formview that I can't figure out how to wire up properly. The formview contains detail info, but the ddl needs to list the entire set to items. Then I want the ddl's selected value be set from the recordset intended for the formview. I think it's just a timeing issue s I would like your help. Thanks, - EJM.
I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.
With a Gridview, if I have a boundfield or templatefiled with visible="false" I can't get the data. I need access to some data of a field, but don't want to have it showing up in the gridview.How do I do that?
I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
I have no problem when paging my FormView, the dropdownlist does not read the next record and keep the value of the first loaded record? All other textbox control behave normally and move from record to record excepted the ddl??Here the code.
Public Sub DoData() Dim myConn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString) Dim myCommand As SqlCommand = New SqlCommand("SelectSupplier", myConn) myCommand.CommandText = "SelectSupplier"
I am inserting 4 fields into a table trought an SqlDataSource and a FormView element. These fields are ID (autopopulated), date(selected from calendar and/or todays date as default), Company name(user input), and UserID (taken from LoginName?).
I am able to inser the data in to the table when typing it, but I would like to have the UserID fiel auto completed and the date as well, or filled with the selected calendar date.
This is my part of my code.-------------------------------------------
My problem i am facing is that i do not know if it's possible to access a single field in my case sold from the following code.
[Code]....
What i want to do is have the checkbox true if the value of sold = yes and false if the value = no I have the checkbox ready on the asp.net side but just need for the checkbox to recognise the datafield, sold, and do and if check statement, is this possible if not i will work around it.
I am trying to bind two values "start_time" and "end_time" to a text property of a label that is inside of a gridview template field. Below is the html. I must keep the values separate so that I can pass them into a function in code beheid in order to calulate the time difference. When I bind the code below I get "The server tag is not well formed." Time is in format HH:MM AM or PM
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.
