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?
How to bind nullable bool to checkbox in MVC 2. I try with this code in view:
<%: Html.CheckBoxFor(model => model.Communication.Before)%>
But show me compilation error.
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.
I have a textbox that I use to gather a date. I would like to have the database store a null if this field is left blank by the user when submitting. I am using the following on my aspx page:
<div class="col-md-3">
<strong>Date Submitted to TDI</strong><br />
<asp:TextBox ID="sub_tdi_dt" runat="server" Enabled="true"></asp:TextBox>
<asp:ImageButton ID="sub_tdi_dt_cal_popup" Enabled="false" ImageUrl="Images/calendar.png" ImageAlign="Bottom" runat="server" />
<ajaxToolkit:CalendarExtender runat="server" BehaviorID="sub_tdi_dt_CalendarExtender" PopupButtonID="sub_tdi_dt_cal_popup" TargetControlID="sub_tdi_dt" ID="sub_tdi_dt_CalendarExtender"></ajaxToolkit:CalendarExtender> </div>
I have tried using the following in Page_Load, but it doesn't work - I still get '1/1/1900':
DateTime? sub_tdi_dt = null;
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 RepliesI have this in my Model
[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?
created 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?

I 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:

I have a data table that has several columns, one of which is an xml field. I want to bind a column in the gridview to a single node in the xml based on an xpath. The binding only needs to be read only, it won't be used to update. How would I do that?
So, given this data:
IDField, XMLData
1, "<Person><Name>FunkyD</Name><Age>110</Age></Person>"
2, "<Person><Name>Maurice</Name><Age>16</Age></Person>"
I want bind the first column of the grid to IDField - that's easy. I also want to bind the second column of the grid to the Name node of the XMLData field. The xpath would be Person/Name.
I'd want the grid to display:-
1 FunkyD
2 Maurice
NB, the node will only appear once in the xml field of each row. I want a row on the grid for each data row. What I don't want (and all I seem to be able find examples of on google) is to bind a grid to nodes that repeat within the same xml doc.
Is it possible to display the result of a function instead of the value of a property in a DetailsView Field?

I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.
For example, I have 4 textboxes currently that have Address, City, State, Zip. I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID.
How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
I got the difference between Bind and EVal from here. Bind will do both way reading and writing. And Eval do only reading. So any function only for writing?
View 1 Repliesif I am binding a list of users to a dropdown list - how do bind it so that the display value is their FirstName and LastName (with a space between them)?
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

I have been at this for two weeks now without any success but I know I have to get a solution to move forward with my design. Is there any way to bind data from a SQLDataSource to a Hiddenfield or Textbox WITHOUT binding via the data controls like gridview, formview, datalist, etc. I do not want to use any of those controls. I need to do inline binding. Please provide the working code example. The hiddenfield or textbox would be named eid. The SQLDataSource name is GetDataEid. Again, if you reply and you submit code I can try please provide the full working solution. These do not work. They have already been attempted:
<asp:HiddenField ID="HiddenField1" runat="server" Value="<%#Container.DataItem("FieldName") %>" />
<input type="hidden" id="hdnId" name="hdnId" runat="server" />
and write the following code in your page load method
hdnId.Value=yourDbValue.ToString();
asp:HiddenField ID="hid" runat="server" Value='<%#Eval("column name") %>' />
I'm using the below code to populate a label inside my insert template with the logged in users' name...
<asp:Label runat="server" Text="<%# Membership.GetUser().UserName %>" id="Label1">
</asp:Label>
Now that my label gets the UserName how can I also bind this label to the field "name" in my database when the user submits?
