How can i use a checkbox to represent a boolean bit field in an MVC View? Out of the box, it defaults to a textbox..There is no boolean datatype in SQL Server 2008 so i used a bit datatype. I guess its a custom template but i cant seem to get the syntax right.
View 2 Repliescreated a create view for an entity in my Linq model which had a bit field in it but it turned out a textfield..can you give me an example of an ascx that will enable me use a checkbox for this instead of a textbox, which the create view template uses for ALL the fields.Also, how can i get the template to use html.displayfor() instead of html.textbox?
View 5 RepliesI know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

When on the view the validation doesnt fire stating that it is required - where as the other values do (such as strings or integer fields )- how does this work for Booleans?
I don't know how to bind nullable boolean field to RadioButton in ASP.net.
Following code works well for non-nullable field
<asp:RadioButton ID="rbStatus" runat="server" Text="Accepted" Checked='<%# Bind("Status") %>' />
how I can bind nullable boolean field to RadioButton?
I'm having problems passing values from the controller to the view. I created a boolean variable to use as a flag and want the view to render some html based on whether its true or false.
Unfortunately ViewData doesn't look like it can pass boolean values. I should be able to pass any datatype to a view (string, int, bool, etc...)
What i would like to accomplish is that a partiel view contains a form. This form is posted using JQuery $.post. After a successfull post javascript picks up the result and uses JQuery's html() method to fill a container with the result.
However now I don't want to return the Partial View, but a JSON object containing that partial view and some other object (Success -> bool in this case).
I tried it with the following code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(int id, Item item)
{
if (ModelState.IsValid)
{
try
{
[Code].....
However I don't get the HTML in this JSON object and can't use html() to show the result. I tried using this method to render the partial as Html and send that. However this fails on the RenderControl(tw) method with a: The method or operation is not implemented.

I am trying to tie the Visible property of two textbox controls in a gridview to the value of a property. One I want to be visible is the property is true and one I want to be visible is the property is false. I have not been able to figure out how to express this. I have tried the following, with the non-working line in red.:

The "Not IsInEditMode" does not work as desired. The property code in the VB code behind is:

What is the proper way to code the Visible= property?
I remember being told that you can add some syntax to the end of a statement that will do something if the field is null. Pretty vague, but I cant seem to find anything about it via google.
I definitely isnt how to set a field to be nullable. I know that.
Here is an example of what I want.
int? field1 = 0;
field1 = int.parse(string2); (where string2 is a passed value, that could be null)
I thought there was something you could put at ?? if it is a null, such as:
field1 = int.parse(string2) ??;
Or do I have to check every if every string2 is null before making that statement.
n a grid view I have a column named REQUIRED which has a value of either 0 or 1.I added a checkbox templated field to show the above as checked or unchecked instead of0 or 1. I decoded the value Y or N to 1 or 1 in the sqldatasource
<asp:GridView>
<asp:CheckBoxField DataField="BOARD" ReadOnly="True">
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
heckBoxField>
When I tried to add the following "Checked='<%# Eval("BOARD") %>' it does not like it and gives an error.How do accomplish the same for the above checkbox field and the exact syntax to be used
When using the "add view" dialog in vwd is there a common practice for presenting any primary key fields as readonly to the user in the view?
By default it appears the user could change the key field value (as it is presented in a textbox) and overwrite data for that record for which the key was accidentally changed to.
Do we have to store the original record's key and then make the key presented as a label and then on the update subtitute the original key value back in for the record? Or is there something simpler?
Where i can find documentation about expressions and syntax of WebForms view engine?And what is the difference between <%: expression %> and <%= expression %>
View 2 RepliesThis question appear when I worked with partial view (MVC3/Razor), but I am sure - it's clear Razor Syntax question, not related direct to partial view. So - I have partial view Menu.cshtml with full markup as:
@model IEnumerable<SportsStore.WebUI.Models.NavLink>
@foreach(var link in Model)
{
@Html.RouteLink(link.Text, link.RouteValues);
}
No problem - "parent" view call it @{Html.RenderAction("Menu", "Nav");} and all work as magic.
But, if I will edit the Menu.cshtml as:
@model IEnumerable<SportsStore.WebUI.Models.NavLink>
@foreach(var link in Model)
{
Html.RouteLink(link.Text, link.RouteValues);
}
(see - NO '@' before Html.RouteLink!) all just broke: now @{Html.RenderAction("Menu", "Nav");} output is totally empty, no one HTML tag. Want to know - what is the difference between two piece of code? I assume @ before foreach also automatically "drop into" and apply to Html.RouteLink as well? So - am I wrong?
I am gettinga syntex error. Is Primary field is a bit data type in the database.

The following CLR syntax works fine in my aspx page:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>
But this C# syntax does not:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>
Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:
public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
{
get { return (TModel)HttpContext.Current.Items["model"]; }
}
}
For reporting we used report RDLCs and displayed using an ASPX form. We implemented using the route as shown below. This resulted in forcing us to use the page route below and also to use the hyperlink instead of the normal Action Link. The question is how do we convert the asp:hyperlink ASPX syntax to Razor syntax.
//Custom route for reports routes.MapPageRoute( "ReportRoute", // Route name "Reports/{reportname}", // URL "~/Reports/{reportname}.aspx" // File );
<li><asp:HyperLink ID="hypReport" runat="server" NavigateUrl="<%$RouteUrl:routename=ReportRoute,reportname=StaffRpt%>">Staff Report</asp:HyperLink></li>
When I put a part of my form in a partial view, all form parts get unobstructive syntax except the form elements in the partial view. The only way I found how to "apply" the unobstructive syntax, is by starting another form inside the partial view.
@using (Ajax.BeginForm("SubmitHandler", new DefaultAjaxOptions()))
{
@Html.EditorFor(m => m.Name)
@Html.Partial("MyPartialView", Model)
}
PartialView:
@Html.TextBoxFor(m => m.SomeContent)
<input class="text-box single-line" data-val="true" data-val-required="This field is required." id="Name" name="Name" type="text" value="">
<input id="SomeContent" name="SomeContent" type="text" value="0">
So only the input element from the View has the unobstructive syntax and the partial view hasn't... Is there a way to apply unobstructive syntax inside a partial view, wich doesn't require you to begin a new form?

This is probably a simple question, but I can't seem to find an answer. One of my web pages has an ASP.NET FormView and two SqlDataSource controls. I need to show data from both datasource controls in the FormView. Most of the data will come from datasource1, with 2 or 3 items coming from datasource 2. The way I am trying to do this is by adding a label to the formview, then use custom data binding to get the data from datasource2. However, I can't seem to figure out the syntax for the bind statement
View 2 Replies.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 am working with a sql server database with about 50 stored procedures. The database and stored procedureswere not created by me. The stored procedures all begin with a number in their name.
Example: 17P_Comsetter
The problem I am having is that if I try and execute the stored procedure at the command line in Query Analyzer,the query analyzer appears not to like that the stored procedure begins with a number. For example:
If I try an run the stored procedure as follows:
EXEC 17P_Comsetter
Then I get the following error message:
Msg 102, ..... Incorrect Syntax near '17'
I am using SQL server 2005. Does anyone know why I am getting this error message?
I have the following returned in my store proc:
Key, Name, IsReadonly.
What I would like to do is show only the Name and IsReadonly and hide the Key field .
I think u can use a it as a Date Key or something because i then want to delete a record (using autogeneratedeletecolumn)and use that Key in the where clause.
