Web Forms :: RequiredFieldValidation Codebehind - Return The Page Data With The Missing Fields
Jan 19, 2011
I am putting a C# asp.net web form together that has a number of fields that we want to ensure data is inputted in them. I have added the RequiredFieldValidation control, but I am unsure what to put in the Button_Click event. I want the click event to check the fields and if not filled in, preserve the fields that already have data and then return the page data with the missing fields so that they user can take corrective action.
there I have a situation where I need to make to call to a normal .aspx page from asp.net mvc web application. How can I make this request and get data back from the page. the data will be returned on on the page_load event of the .aspx page
Im not sure what i could have done wrong here but i created a dataset (ran a query and it returns the correct data) - created my BLL class - bound the ObjectDataSource to the control using the BLL - ran the site and all the data is showing as expected. Now i click edit columns (from DetailsView smart tag) and the selected fields are empty. I refresh the schema and this makes no difference. What could i be doing wrong?
I have a page with 1 RequiredFieldValidation control on it. This same page also displays a popup. The popup has a linkbutton on it. When the link button is clicked the validation control displays that a value is required on the underlying page. To be clear the validation control does not display on the popup. It displays on the page where it belongs.
It seems that I would need to disable the validation control when displaying the popup.
I am starting a new project in Asp.net MVC 2.I have been mostly a webforms developer and have limited exposure to Asp.Net MVC and hence this is probably a noob question.
My situation is as follows:
I have a create page for saving some data to the DB. The view for this page is not strongly bound / typed - so the way I am extracting the data from the view is by looking at the POST parameters.
Incase there is an error (data validation, etc), I need to send the user back to the previous page with everything filled in the way it was and displaying the message.
In one of the steps of a wizard control are 2 dropdownlist which data come from 2 distinct queries and cascade from the 1st one to the 2nd one. Where and how can code for that data binding and cascading be placed since it seems codebehind window for both of the dropdownlists cannot be found in VS property or event windows?
<WebMethod()> _ Public Shared Function GetDate() As String Return DateTime.Now.ToString() End Function
I need this to populate the inside of the div with the string returned by the GetDate() function. I think this should use code similar to this:
[Code]....
I've pulled this example from this site: [Code]....
However, I simply cannot get it to work. Nothing happens. This is just a regular asp.net web project. I haven't done any sort of Ajax-enabling business other than including script tags in my markup to reference jquery.
Here's what the firebug console tells me when I click on the div:
POST http://admin/Default.aspx GetDate 404 Not Found -18ms
Edit: Note: test.aspx/GetDate must match your aspx page name and function name!
I have a method in my button code to run the query, it returns a value and save it to a Session variable to be used later, this code works.Dim connString As String = ConfigurationManager.ConnectionStrings("DBConnectionString").ConnectionStringUsing myConnection As New SqlConnection(connString)
Const sql As String = "SELECT Rate1 FROM Rates WHERE (LayerID = '01')" Dim myCommand As New SqlCommand(sql, myConnection) myConnection.Open()
I have a form for registering customers, with RequiredFieldValidations that each are bound to a specific textbox. My problem is that I would also like to bind them to one specific buttonclick, since I have other buttons which I don't want to trigger the validations. Is that possible?
the page form has a hidden slide-in on click of a div, section allowing the user to 'make a reservation'. The jQuery used to animate the slide works fine, and happens on click on the ticky check-box (id="rescheck"). The problem is, instead of all the fields contained within the hidden div displaying on click of the checkbox, and thus sliding into view along with their labels, only one text field input shows, and nothing else. Checking the source code shows that these missing labels & fields are not even in the source code, dispite being in the page code when viewed (and edited) within MS Visual Studio 2008. As you can see, the fields and their labels seem to just disappear in the browser! I have NO idea whats causing this, and am not sure where to go with it next.
This is my PAGE code, from Visual Studio:
<fieldset id="resreq"> <legend>Make a Reservation?</legend> <label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label> <input id="rescheck" type="checkbox" class="rescheck" runat="server" /> <div id="reservationfields"> <div id="res_when"> <div> <asp:Label ID="lblDate" runat="server" AssociatedControlID="txtDate">On which date would you like us to reserve your table?</asp:Label> <asp:TextBox ID="txtDate" runat="server" CssClass="res_date" /> </div> <div> <asp:Label ID="lblTime" runat="server">and for what time?</asp:Label> <asp:TextBox ID="txtTime" runat="server" CssClass="res_time" /> </div> </div><!-- close res_when --> <div> <asp:Label ID="lblBranch" runat="server">At which restaurant would you like to make your reservation?</asp:Label> <asp:DropDownList ID="ddlBranch" runat="server"> <asp:ListItem Text="Select a Restaurant" Value="" /> <asp:ListItem Text="Restaurant 1" Value="Restaurant 1" /> <asp:ListItem Text="Restaurant 2" Value="Restaurant 2" /> </asp:DropDownList> </div> <div> <asp:Label ID="lblPeople" runat="server" AssociatedControlID="txtPeople" Text="Number of Guests:" /> <asp:TextBox ID="txtPeople" runat="server" /> </div> <div> <asp:Label ID="lblDOB" runat="server" AssociatedControlID="txtDOB">Date of Birth:</asp:Label> <asp:TextBox ID="txtDOB" runat="server" /> </div> </div><!-- close reservation fields --> </fieldset> ...and this is the Source Code when you 'view source' in the browser: <fieldset id="resreq"> <legend>Make a Reservation?</legend> <label for="rescheck" class="rescheck">If you would like to reserve a table at Madrasi check here:</label> <input name="ctl00$cpcMain$rescheck" type="checkbox" id="ctl00_cpcMain_rescheck" class="rescheck" /> <div id="reservationfields"> <div id="res_when"> <div> <input name="ctl00$cpcMain$txtDate" type="text" id="ctl00_cpcMain_txtDate" class="res_date" /> </div> <div> </div> </div> <div> </div> <div> </div> <div> <span id="ctl00_cpcMain_rvDOB" style="color:Red;visibility:hidden;">You have entered your Date of Birth incorrectly (dd/mm/yyyy).</span> </div> </div><!-- close reservation fields --> </fieldset>
if i have string with "1,2,3,5" how can i have another record at least to have "1,2,3,5" in new data if it is "1,2,3,4,5" then it is true. if the new data is "1,2,3,4,6" , then return false becuase it is missing 5.
I have selected the tables using the wizard, but for some reason CR doesn't display all the fields in the tables, so there are some tables in Field Explorer that lack some fields. The fields that aren't shown are both int, and varchar, some of them allow nulls and some of them don't, I can't seem to find a pattern as why some fields aren't loaded into Field Explorer.
i want to read lbl_TotalCount value after changes value's.i when click on the client Button with named Button1,the lbl_TotalCount value increase.but,when i click the server Button with named btn_saveForm, value of lbl_TotalCount is zero.
I have an ASP.NET TextBox with TextMode = TextBoxMode.MultiLine that is used within an AJAX Update Panel. The .Text value has been pre-set to a value that has multiple lines.
When using Chrome(7.0.517.41) or Firefox(3.6.11) working with the controls posted back value on the server the carriage return is lost if the user hasn't edited the pre-set value.
The application.aspx page contains a multiview, and the applicant1 user control is in one of the views. The button continue takes the visitor to the next view which contains another user control of text boxes.
I want to write validation code on the continue_Click event which is in the application.aspx.cs page. Ideally, from the application.aspx.cs code behind page, I want to get the user input from a text box in applicant1.
Intellicense cannot seem to find any of the text boxes in applicant1 from application.aspx.cs.
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
im using listview to display my products and also use pager and count 10 item per page. my problem is, when i click one of the products to see big image and info about the product (in new page) i have some back button to return to the products page its return to number 1 even if i select product from pager 8, how can i return to the page were the last product was (like: 8 or 14) and not to the first pager?
