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.
I have a type that is derived from an Entity generated by the Entity Framework 3. How do I assign one Customer's Order property to the Derived Customer's Order property?
derivedCustomer.Orders = customer.Orders
I'm not actually trying to swap orders; this is just an example of what I am trying to achieve. Has anyone done tried this and succeed?
When I open an ASP.NET 3.5 project using VWD2010, I get a prompt error message,"The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place."however, my project works successfully.
foreach (DataGridViewRow item in dataGridView1.Rows) { if (Convert.ToBoolean( item.Cells[0].Value) == true) { foreach (DataGridViewColumn col in dataGridView1.Columns) { **class oclass=new class(); oclass.property = item.Cells[col.Name].Value.ToString(); Collection.add(oclass);** } } }
In the above syntax,i want to fill class property dynamically.I also add my class in collection.Is it possible in C#,fill class property dynamically?My grid contain more than one column.My grid's column name are same as class property name.I want to do the bellow thing:
foreach (DataGridViewColumn col in dataGridView1.Columns) { **class oclass=new class(); oclass.col.Name= item.Cells[col.Name].Value.ToString(); Collection.add(oclass);** }
I have a custom class downloaded from internet. In this class, there is a properties where by the value can be either 0, 1 or 2 only and I MUST assign it during run-time. But some how, this assignment only work using VB, and not C#.
[Code]....
In C#, it the compiler said "missing cast or conversion...". But in VB, it works perfectly.
I have a list <Department> say Company.Departments with object Manager and ManagerId, ManagerName as property of Manager. I would like to fill the dropdownlist with managers as below
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:
[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?
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.
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.
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!
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.
I am trying to use Rounded Corner buttons in my ASP.NET website using AjaxControlToolkit's RoundedCornerExtender. When I use this on a Buton control, I get an error saying "htmlfile: Unexpected call to method or property access" to which I can Break/continue.
When I run the sites, it gives me an error "Unexpected call to mathod or property access".Here's the screenshot:
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
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.
[code]....
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.
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?
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
Can we write property in property?IN the page load event we have page property and we can find another page property in that page property.Pls let me know how this is happening
