i want to add items to a gridview in asp.net from a custom class. The class has Properties X and Y. Does anyone know if im able to add special attributes to these properties so i can just add the class and not have to muck around?eg..
[Column("Name")]
public string Name { get; set; }
Ideally i can then write something like..
this.gridview.datasource = instanceOfMyClass;
Say I have a class:
public class TestClass
{
public String Str1;
public String Str2;
private String Str3;
public String Str4 { get { return Str3; } }
public TestClass()
{
Str1 = Str2 = Str 3 = "Test String";
}
}
Is there a way (C# .NET 2) to iterate through the Class 'TestClass' and print out public variables and attributes?

How do I specify size,maxlength,class and other attributes for the
<%= Html.TextBoxFor(model => model.XXX) %>
I know this is kind of obsessive, but is there a way to control the order that the TagBuilder class renders the attributes of an HTML tag when you call ToString()?
i.e. so that
var tb = new TagBuilder("meta");
tb.Attributes.Add("http-equiv", "Content-Type");
tb.Attributes.Add("content", "text/html; charset=utf-8");
tb.ToString(TagRenderMode.SelfClosing)
will return
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
not
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
Changing the order that you add the attributes doesn't change it, it seems to be rendering in alphabetical order
I have a fck editor in which the user enters some text. And in the code i want to strip the class,id attributes of the text posted. I know this can be done through regular expressions And i have written some code to do so but unfortunately it's not working.
private string RemoveScripts(string input)
{
string re1 = "(.*?"; // Non-greedy match on filler
string re2 = "(class)"; // Word 1
string re3 = "(=)"; // Any Single Character 1
string re4 = "(".*?"))"; // Double Quote String 1
string re5 = "(id)";
Regex regClass = new Regex(re1 + re2 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
Regex regID = new Regex(re1 + re5 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
input = regClass.Replace(input, new MatchEvaluator(ReplaceClassID));
input = regID.Replace(input, new MatchEvaluator(ReplaceID));
return input;
}
private string ReplaceClassID(Match m)
{ return ""; }
I have found hints that MVC 2 recognises the 'buddy class' type of property metadata, where data annotation attributes are applied to a 'buddy' metadata class, and the MetadataType on the actual entity class points to that buddy class, as below. However, as below, it seems the only attribute that makes any difference to the rendered UI is DisplayName. Why are the other attributes like DataType, Required, and ReadOnly not working? I.e. why can I enter text in a read only field? Why do I not get an error when a required field is empty? Why does the DataType attribute have no apparent effect? Why does EditorForModel not include validation messages?
[MetadataType(typeof(CustomerMetadata))]
public partial class Customer
{
public class CustomerMetadata
{
[ScaffoldColumn(false)]
public object CustomerId { get; set; }
[DisplayName("CustomerNo.")]
[ReadOnly(true)]
[Required(AllowEmptyStrings = false, ErrorMessage = "Customer No. is required.")]
public object CustomerNo { get; set; }
}
}
I find behaviour the same whether I use an explicit LabelFor and TextBoxFor for each model property, or a single EditorForModel for the whole model.
I have a menu generated by my cms:
<ul>
<li><a href='default.aspx?pageid=2' id='link2'>rrr</a></li>
<div runat='server' id='menu2'>
<a href='default.aspx?subpageid=8'>rrr</a>
<a href='default.aspx?subpageid=9&siteid='>rrr</a>
<a href='default.aspx?subpageid=10&siteid='>rrr</a>
<a href='default.aspx?subpageid=11&siteid='>rrr</a>
</div>
<li><a href='default.aspx?pageid=3' id='link3'>Your Services</a></li>
<li><a href='default.aspx?pageid=4' id='link4'>rrrrrr</a></li>
<div runat='server' id='menu4'><a href='default.aspx?subpageid=1'>Single Equality Scheme</a>
<a href='default.aspx?subpageid=2&siteid='>Diversity Strands</a>
<a href='default.aspx?subpageid=3&siteid='>Equality Impact Assessments</a>
<a href='default.aspx?subpageid=4&siteid='>Quality and Safety Committee</a>
</div>
<li><a href='default.aspx?pageid=9' id='link9'>Contact Us</a></li>
</ul>
I would like to change the link that has been clicked, to class="active". I would like to add a class to the div if the page above is clicked too.
If (Len(Request.QueryString("pageid")) <> 0 and Request.QueryString("pageid") = 4) Then
menu & Request.QueryString("pageid") & .Attributes.Add("class", "active")
link & Request.QueryString("pageid") & .Attributes.Add("class", "activelink")
end if

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use
Body.Attributes.Add("class","value")
So I need to check if the class attribute exsists and if it already contains the value Im going to add.
If Not Body.Attributes("class").Contains("value") Then
Body.Attributes.add("class", Body.Attributes("class") + " " + "value")
End If

I have added a Command Field in a Gridview Dynamically. And I have added the OnClick Attribute in the
RowDataBound event
[code]...
and ProceedAction() function have confirmation message. When i click the Delete button, the confirmation message is shown. But the Row Command is not fired (even if i click Ok/ cancel in the confirmation message).
I have analysised Little bit. If i have '\' or '{, }' or '*' in the javascript function, the behavior is improper (as i said above). If i remove it, it is working fine.
Since i need to ask two confirmation, i need to put '{, }' in my javascript. So how can i resolve the above issue.

View 2 RepliesI have a gridview, and I want to change the backcolor of any row that has the column checkedin = false.
I have this working fine, except that it will not change the backcolor of the first row and only the first row. Matter a fact if I sort the columns by clicking on the header rows the order changes and the backcolor highlights the row that was the first row before it was sorted so long as it is not the first row. I actually removed all formatting from my gridview and still the same issue.

I think the title pretty much says what I'm trying to do. I'm trying to make several applications with C#, ASP.NET, and active directory. Right now, I'm trying to create a report for my manager that shows all the active directory attributes of the current user. Could someone show me the code for this. I would want to add a new row into a datagridview for each attribute.

it returns an error , cannot convert single result to queryable!! in " blo= DB.MarketList(TypeID);"

i added this GridView on Toolbox. Every Thing is ok . İ want to add my own CSS design to my GridView. But if i drow this gridView from toolbox to aspx page. if i bind my datasource ; Datasource is not show himself.
Like that Main program:
protected void Page_Load(object sender, EventArgs e)
{
LoadData loaddata = new LoadData();
DataTable dt = loaddata.LoadSQL("conn", "sp_GetAllCategory");
MyGridView1.datas.... -----> i can not see DataSource why?
}
i want to see My GridView DataSource. if i write Binding datasource. MyGridView1.DataSource -----> i can not see DataSource why?
I have the following classes (pseudocode):
Item ( int Field1 )
ItemDetail : Item (int Field2, string field3)
If I set ItemDetail as the datasource for an asp.net gridview:
grid.DataSource = new List<ItemDetail>();
grid.DataBind();
Can I use Field1 in the GridView? If so, what is the correct DataBinder syntax? The following code blows up trying to cast to an Item:
<%# DataBinder.Eval(Container.DataItem, "Field1") %>
EDIT: And I'm a moron. I had copied the gridview and was calling a RowDataBound event handler for a different grid... Sorry to have wasted everyones time, but there is some good info here regardless if anyone has the same question. In the end, the public properties of the base class are binding correctly.
I have a class Person that represents a person in my database. This class has a CategoryId property (int) and a Category property (type Category).
Category is a class that represents a category in my database. csharp Code:
public class Person{ public int Id {get; set;} public string Firstname {get; set;} public string Lastname {get; set;} public int CategoryId {get; set;} public Category Category {get; set;}} public class Category{ public int Id {get; set;} public string CategoryName {get; set;}}
[code]....
I am displaying a list of these Persons in a GridView, and I would like to display the name of the Category (the CategoryName property to be precise). So I define this markup;
xml Code:
<asp:GridView runat="server" ID="personsGrid" AutoGenerateSelectButton="True" AutoGenerateColumns="False" DataKeyNames="Id"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" /> <asp:BoundField
Usually I would solve this problem by one of two ways:Override the ToString method of the Category class and return the name.
Add a readonly 'CategoryName' property to the Person class, where I return 'this.Category.CategoryName' (and then bind the column to this property instead).
In this case however, I am using the Entity Framework, and the Person and Category classes are automatically generated by the database model. I suppose I could edit the generated code manually, but I don't like that, since any change in the model will cause VS to re-generate the code and my changes would be lost. So these two methods are not going to work...
The simple question remains: how do I make the Category column show the CategoryName property of the object it represents, rather than just the type name?In a DropdownList for example (which I am already using for the user to select a category when creating a person), I can set the DataTextField (to "CategoryName") and DataValueField (to "Id") properties and it displays the right name and uses the right value (the Id). I can't find anything similar for a BoundField though... Am I overlooking something obvious?
Another solution would be if I could tell the Entity Framework model to add another property to my Person class which returns the CategoryName of the Category. I can't find any way to do that though (I am a compleet noob in EF),
I've built a control that inherits from a Gridview. I also have a class where I extended DataControlField, so I can make a custom Gridview column.
Everything works great on a normal aspx page that gets refreshed everytime I load tha page or paginate through the gridview.
The code always goes through the extended DataControlField Class and rebuilds the gridview columns etc.
I tried adding my gridview inside an updatepanel today. set the updateMode to conditional(currently have a normal asp gridview in it and that works well).
the grid loads fine on the initial load, but if I try to page it breaks. It never goes through the extended DataControlfield class. I place a breakpoint there. and because of this my code in the gridview class gives me errors.
what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.
View 1 Repliesi have a list of contacts (generic list) and i bind a gridview to it, i get the list displayed on the griview that fine, now i'm trying to get a contact object when i click a button on the gridview (button is a template field) i want to get the object back from the generic list, not just an ID using data key names, even the index of it in the generic list will do.
View 6 RepliesDoes anyone know if it is possible to create a gridview from a class on a seperate webpage?
So I have webpage 1, that calls Class 1, in Class one there will be a Select Query that will call some info from a database and then return it to a gridview. The gridview wont work obviously as it is in the class and not on webpage 1.
Is there anyway to reference the fact I would like the gridview created on webpage1?
I am trying to set a focus on a dropdown within GridView(gridViewDropDown class) when page loads:
if ($('select.gridViewDropDown').length)
{
alert("Found my dropdown");
//$('select.gridViewDropDown:first').focus();

}
I can see the alert which means that dropdown is found but it never gets a focus. What do I need to change here? I am using IE 6/7.
i try to increment value from class and display in a gridview as a number for the row.
