Error - Property Access Must Assign To The Property Or Use Its Value

Sep 10, 2010

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.

<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox>
<a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">

However, I keep getting this error:

Property access must assign to the property or use its value.

How would I be able to accomplish this?

DataSource Controls :: Assign A ParameterPrefix Property To A GridView?

Feb 23, 2010

I have a GridView that displays records based on a SQLDataSource, which gets it's data from a very simple stored procedure. I want to use stored procedures to update & delete records in the GridView, which I have done in the past.

Our organization requires that the names of the parameters within our stored procedure start with "@p" to differentiate between passed parameters and internal variables. This is causing me my issue. If I change the stored procedure code to reference the fields without the "p", everything works properly. This is because the SQLDataSource parameters use the default ParameterPrefix of "@" and correctly references the stored procedure parameters. Here is the relevant code:


I found a MS article describing how to override the default ParameterPrefix, but I am unable to implement it. I can add their example code, but how do I "assign" this property to my GridView?

How To Dynamically Assign The ImageUrl Property Of An Image Using Data Binding

Nov 11, 2010

I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.

How To Assign A Control Property Value From A Global Variable In Page Code

Aug 31, 2010

I have a control and list of variables and I want in the control property to be assigned to the variable value directly in the page not from the back code, something like this

My global variables

public string Banana = "banana_pie";
public string Apple = "apple_pie";

in my custom control instead of:

<uc:LoadPie id="pieBanana" type="banana_pie" />

To this

<uc:LoadPie id="pieBanana" type="<%=Banana %>" />

so is there a way or just assign the property in page back code.

Forms Data Controls :: Cannot Assign Values To Checked Property Of Checkbox At Runtime

Apr 22, 2010

I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.

When page loads,I get error - Specified cast is invalid!

The code is as follows...

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />

Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.

Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.

I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.

I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.

Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.

how i can edit and update Checkbox.

where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.

So what I'm trying to accomplish is this

Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.

Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.


As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

C# - Why Does ReSharper Need To Scan All Files When Converting A Property To An Auto Property

Mar 4, 2011

Is there any difference between accessing a property that has a backing field

private int _id;
public int Id
get { return _id; }
set { _id = value; }

versus an auto-property?

public int Id { get; set; }

The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.

I can't see any reason why there should be any difference between the two from outside the class. Is there?

C# - Difference Between Timeout Property Specified In Web.Config And ExpiryDate Property Of FormsAuthenticationTicket?

Jul 3, 2010

In the Web.Config we have a timeout property. Ex:

<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>

When loggin in, we can specify a ticket expiry date. Ex:

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);

Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?
