i already have a DataList, and i get any information from the rows i need by adding code such as:
[code]....
Well what i am doing there is using the values from the items that the DataList has obtained from the rows, now, what i need to do is EXACTLY the same, but for the FormView, i realised that this code does not work for the FormView, but only DataList control.
give me the code for doing exactly as shown, but for the FormView control.
I have a very simple form that contains a FormView Control Bound with a SqlDataSource, The DefaultMode of the FormView control is "Insert". I noticed that when I run the page for the first time, the databinsing and databound events of the FormView Control occurs after the PreRender Event of the page ! I know very well the life cycle of a page, but I dont know when the data binding occurs in the life cycle of a page and if it can differ from a control to another.
Is there an article or a tutorial explaining all those things.
I have a page that has a formview on it. Client info, name, address, usual stuff. The formview is populated by a DataSource, that calls a SQL stored procedure for the client info. It all works great.Within the formview, I have a dropdownlist for the Staff assigned to the client (StaffId is a member of the Client record called during the Formview binding). When the formview is in Item mode, the Staff name appears in a label, when in Edit mode, the dropdownlist is bound and populated by another DataSource that calls a stored procedure of ActiveStaff. When the assigned staff exists, the StaffId is correctly bound to the DDL SelectedValue and the current staff name appears selected in the DDL when in edit mode, as it should.
I'm working in a web application and my page is using a databound formview control. When i first enter the page via my code, I am unable to retreive a value from any of my controls -e.g. when i debug, i see that tbDate.text has no value (see code below). How can I retreive the values from the controls on my page e.g text boxes?
Code:
if (!this.IsPostBack) { TextBox tbDate = (TextBox)FormView1.Row.Cells[0].FindControl("txtDate"); }
I am "trying" to switch my form from SqlDataSources to ADO.NET data sources. So I have a DAL setup, and ObjectDataSources in my form referencing these DALs. These data sources are bound to the form's objects. So far so good. In the InsertItem Template of one of the form's FormViews I have a list box that I am trying to populate with a value pair (ID, TechName) from a database table and I get the following error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." Apparently, one of the two workarounds involves programmatically loading the listbox. The code below shows one of my attempts, resulting in the above mentioned error:
Code: Protected Sub TestFillDefaultValueInFormView() Dim vInspectorList As DropDownList If (FormViewHydInspection.CurrentMode = FormViewMode.Insert) And Not IsPostBack Then vInspectorList = DirectCast(FormViewHydInspection.FindControl("DDlstInspBy"), DropDownList) vInspectorList.Items.Clear() Dim vInspectorDA As New DataSetHydrantsTableAdapters.TechnicianTableAdapter() Dim vInspectors As DataSetHydrants.TechnicianDataTable = vInspectorDA.GetTechnician() Dim vInspRow As DataSetHydrants.TechnicianRow Dim vInspectorHT As New Hashtable vInspectorHT.Add("0", "Select Technician") For Each vInspRow In vInspectors If vInspRow.TechID <> 0 Then vInspectorHT.Add(vInspRow.TechID.ToString, vInspRow.TechName) End If Next vInspectorList.DataSource = vInspectorHT vInspectorList.DataTextField = "value" vInspectorList.DataValueField = "key" vInspectorList.DataBind() End If End Sub
I tried populating the listbox directly using the Listbox.Items.add() method (which is the way I have it now so I could continue solving other problems, and it works!) but I could not find a way to add a value pair. I did try:
vInspectorList.DataTextField = "Select Technician" vInspectorList.DataValueField = "0" but that left a listbox without any data.
I get the Subqueries are not allowed in this context. Only scalar expressions are allowed - i am going to run into this quite alot so I figuredI'd better see what the right way is!
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
i have a FormView, and i already have a Label control that gets the value of theselected propery inside the FormView, so each time the FormView displays data, i have a Label control that displays individual values, according to the value of the FormView, here is the code:
[code]....
What i would like to do is to know how i could add a DataList instead of a Label, and then each time the FormView databinds an item, to show the value of the DataList How would i go about doing that?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
On my main page I have a repeater that pulls the last 3 entries from the database. I want to be able to add pictures to the database and show those in the repeater, but only if the column is set to true. I can't seem to get past the part about have the image show only if its supposed to.
Here is the code for my page:
[Code]....
Code Behind:
[Code]....
SP:
[Code]....
So my questions are: Is the repeater the correct control to use?
How do I only show the image control if the column "NewsImgShow" is true?
I have a listview, that shows 8 rows until creating another page to navigate to to see the rest. I can't figure out where the limitation of the number of rows is coming from
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)
My filter Expression was working fine with filtering by Control Parameters.When I added the Phone Parameter it went nuts - with the Phone Parameter the GridView just Comes out blank upon loading the page (without it would show Select * from Individuals)Is it because the phone field is populated with numbers? Don't get it.... In the SQL server the 'phone' field is set to 'varchar(30)' and nulls are allowed.here is my code:
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'm parsing a few .net resource files (.resx).In that, i have this piece of data:informaciónThis works in my .net app, but when i try to load this file in my xml document
XDocument xmlDoc = XDocument.Parse(s);
i get this error:Reference to undeclared entity 'oacute'.
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I am working on this form and I am having a difficult time trying to insert data into the database without having to use gridview, or something like that. I have textboxes and and dropdown lists all over the place and i want enter/selected values to be sent to the DB.
Heres some code:
[Code]....
I understand this code fairly well, but from what i can gather is that is used with DataBound controls. how do i set something like txtProvider.Text to @Provider and also execute the Query?
While writing a web application Using MS Web Developer 2010 Express, I noticed a rather disconcerting behavior of the asp:DropDownlist control.When using databinding and you assign a DataValueField the selectedIndexChanged does not fire or change unless the value of the DataValueField changes no matter what the value of the DataTextField. This means that if I have several different text values(States/Provinces) with the same datavalue (US/Canada) I cannot fire an event if the text changes (the textchanged does not fire either) as long as the datavalue doesn't change (all States are US all Provinces are CA). This would seem to be a counter intuitive behavior?
