I am new to .NET and MVC, so this is most likely a simple question: How can I have a default value appear for an Html.TextBox or TextArea field, for example if the code is currently - <%=Html.TextBox("ApplyToFax", Model.Competition.ApplyToFax, New With {.class = "regular", .maxlength = "50"})%>. I am looking to have a default fax number appear in the box when the page loads, for example (999) 999-9999.

.NET newbie. I know there has to be a way to do this.I have a details view with it's default mode set to Insert. This is to be used as a form for users to enter records into a database. For two of the fields, I want to pre-populate the field with information. Specifically, I have a vb script with a few functions to query Active Directory to return the user's name based upon their user id. This script works fine.I call the functions for the user name like this:
<InsertItemTemplate>
<asp:TextBox ID="txtUserID" runat="server" Text='<%#CurrentUID() %>'></asp:TextBox>
</InsertItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="txtUserName" runat="server" Text='<%# GetUserName(CurrentUID()) %>'></asp:TextBox>
</InsertItemTemplate>
When the page loads, this populates the text boxes with the user id and the user name.But when the form is submitted, the values in the text boxes are not inserted in to the database.How can I set default values for the fields when the values come from functions?
I have a column in my database which contains null value. Now after retrieving value from database i want to store that value in my txtbox. I am getting
[DBTableFieldIsNullException: Field 'Title' is NULL] exception.
The strongly typed helpers are now written like this -
<%= Html.TextBoxFor(model => model.State) %>
I need to add a default value to a textbox. In the prior version of Asp.Net MVC it was easy to assign a default value. I thought doing the following would work in MVC 2-
<%= Html.TextBoxFor(model => model.CountyId, new{ value = 840 })%>
This, however, does not work for me in Asp.Net MVC 2. The value is still blank for the textbox. I want to make sure that this isn't some random error that I am having. Has anyone else encountered the same problem? I have searched and searched to find more information on the default property for the html helpers in MVC 2, but I can't find anything. Does anyone out there know how to correctly assign a default value to a textbox in Asp.Net MVC 2?
I am inserting html into textbox. And whenever I enter anything into the textbox, I want it to see same as i entered in it. e.g. if i type
<b>bold text</b>
then it should show me exactly the same as follows

View 5 RepliesI am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
View 9 RepliesI have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1
View 3 RepliesThe following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
Many WebSites where we asked in textbox to enter text for search, such as above you see "Search Entire Site" in this Microsoft ASP.net website page. Once we click inside the textbox the default message vanishes. So tell me how can i do this?
View 4 RepliesI am trying to add a bit field with a default value of false to an existing table using VWD 2010 Express. With the allow nulls checkbox turned off and no data in the table, any value I attempt to enter into the default value box (0,(0), ((0)), False) all produce an error when exiting the field. What's the secret?
View 13 RepliesI have a FormView that is in Insert mode and at page load I assign the current date to a field in the FormView. This works. But after I click Insert, the default date gets cleared out of the FormView and does not come back.I have stepped through the code in debug mode and even though there is a post back and the page load code runs again, the default field is not populated. For one thing, during this postback, the FormView still contains it's field values.
While stepping through in debug mode, the last thing to happen is the InsertTemplate section of the included code, below. After the last text box is referenced within the InsertTemplate, the FormView values go blank and the GridView that it feeds gets a new row. But processing does not come back to the code behine file and the default date field stays blank.I have been trying to find an event that happens after the FormView empites itself of it's values so that I can set the date field the same way I am setting it on page load, but so far nothing works.
Code:
<asp:FormView ID="FormView_Discussion_Input" runat="server" CellPadding="4"
DataKeyNames="Discussion_ID" DataSourceID="DataSource_Discussions_Input" DefaultMode="Insert"
ForeColor="#333333" Width="695px" BorderStyle="Groove" BorderColor="Black"
BorderWidth="1px">
<FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
<RowStyle BackColor="#FFFBD6" ForeColor="#333333" />

This may be a simple question but here it goes. I have an insert form that captures the current date of entry. What I would like to do is not cause the user to enter or select the current date but have it display on page load and capture to the field in the table on submit.I am rather new to ASP and am using Visual Web Studio 2008.
View 4 RepliesI have this code setup currently:
TreeView tree;
TreeNodeBinding treeNodeBinding = new TreeNodeBinding();
treeNodeBinding.TextField = "Name";
treeNodeBinding.DataMember = "Address";
treeNodeBinding.ValueField = "Zip";
treeNodeBinding.ToolTipField = "FileName1";
tree.DataBindings.Add(treeNodeBinding);
tree.DataSourceID = "Customers";
tree.DataBind();
The datasource (XML) may or may not have an optional attribute called IsPremium. If it exists, then I have to add custom business logic that determines what the treeNodeBinding.ToolTipField is going to be. The custom business logic will generate a string which needs to be set as the value of the ToolTipField.
My web-based app allows users to override values in certain textboxes. If they don't override the value, the system will display (and use) a default.
I would like to support a scenario where the user has overridden the value, but now wants to revert back to the system default value, but doesn't know what value to enter. I would like to provide an intuitive UI for causing the system to revert the field's value back to its default.
Fields occur both on edit forms (where space is plentiful), as well as on edit grids (where space is scarce).
Requiring the user to clear the field is not an option, as sometimes the user's override is an empty value. Would rather not use a keystroke, like Ctrl-Z or ESC.
Best thing I can think of is the user hovers over the field and a popup displays giving the user the option to use the system default. I could use the same popup to capture/display a comment related to the override.

View 3 RepliesSo question from a Newbie !So I have a web page with a Details View component for Inserting data into a table.One of the fields is a date/time which I want to be now().SO I guess there are 2 ways of doing it - either I populate the date/time field in the form with a variable that represent now() and make it Read Only so the user can't change it or I somehow make a hidden variable (ie not displayed in the form) that writes a date/time of now() into the database whenever an INSERT takes place.What is the best way and how do I do either of them ? How do I make one of the fields in the INSERT form of the Details View a preset variable ?

I am using DetailsView to INSERT new records. I have a field "Paid Date"(date) that needs to be pre-populated with the current date. 90% of the time, the user will use the default date, however, there are times when the user will need to change the data as needed. I want to add this default in the code-behind. I DO NOT want to use template item.
