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 a gridview table and i need to select one record and insert the Datakey of the selected record to a formview textbox control. I'm completely lost...
When a FormView control is in insert mode, a data entry form is shown where the user will type a value into each textbox corresponding to a table column.
How do I disable data entry for one of these textboxes and instead, assign a system-calculated value to that text box?
how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.
I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time.
I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do?
i have a dropdownlist control in asp.net which resides in a user control .The yuser control has a updatepannel .I want to set the dropdown selected value to a hidden field .How will i do this in javascript /Jquery .I don't want to use server code?
A TemplateField of a DetailsView can be assigned a value easily at any of many event handlers such as Load, PreRender, etc. when the page is loaded. However, after Insert or Cancel is clicked, all the fields are cleared. I cannot figure out how to assign a value to the field again in code-behind.
Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?
I have a Formview where user is selecting the date and time via dropdown values. I am trying to set the value of the field when the record is being inserted for some reason my database still displays a null value.
Protected Sub FormView1_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewInsertEventArgs) Handles FormView1.ItemInserting CType(FormView1.FindControl("txtActivityDateTime"), TextBox).Text = CType(FormView1.FindControl("ddlMonth"), DropDownList).SelectedValue + "/" + CType(FormView1.FindControl("ddlDay"), DropDownList).SelectedValue + "/" + CType(FormView1.FindControl("ddlYear"), DropDownList).SelectedValue + " " + CType(FormView1.FindControl("ddlHour"), DropDownList).SelectedValue + ":" + CType(FormView1.FindControl("ddlMinute"), DropDownList).SelectedValue + " " + CType(FormView1.FindControl("ddlAMPM"), DropDownList).SelectedValue End Sub
I have done this before but for the life of me I can not figure out why this is not working. I am trying to use a calendar extender on a field in Formview Insert.The page will load fine but no calendar.
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.
I have created a formview with 4 dynamic controls fields that LINQ to a database.

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 have a Gridview with ID "GVSeasonsOfResort" which has selectable rows.
One of the fields in that gridview is RSLinkID which is an ID field of the table from which ths SQLDataSource driving the gridview gets its data.
I have a textbox outside the gridview with ID TxtBxRSLinkID and when I select a row of the Gridview, I want to assign the value of the RSLinkID field of the selected row to the TxtBxRSLinkID.
I've seen this before, I fixed long time ago and now cannot remember how I did :) My store procedure won't update the record because the sql field 'itemId' is being passed as ZERO always.
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 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 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)
This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then Try If pasDate <= System.DateTime.MinValue Then Return Nothing Else Return CType(pasDate, DateTime) End If Catch ex As NullReferenceException Return Nothing End Try Else Return Nothing End If End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
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?
