Forms Data Controls :: Error / OnRowUdating Is Not A Member Of Asp?

Dec 14, 2010

when my application start, browser stops saying that onRowUpdating = "GridView1_onRowUpdating" is not a member of asp:default.apsx.

How can I fix this problem?

I'm using VisualStudio 2010.

Here is the html:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" CellPadding="3"
DataKeyNames="codice" DataSourceID="SqlDataSource1"
EmptyDataText="Non ci sono dati da visualizzare." Font-Names="Verdana"
Font-Size="Small" ForeColor="Black" GridLines="Vertical" BackColor="White"
BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" OnRowUpdating="GridView1_OnRowUpdating">

Forms Data Controls :: GridView.DataKey Error: No Default Member Found For Type 'DBNull'?

Sep 16, 2010

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"

I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:

No default member found for type 'DBNull'. I am using the code below.

What object types are stored within DataKeys (I thought it was just integers or strings)

How to handle a NULL datakey value to prevent this error occurring?

MVC :: Model With List As Member: Member Always Null After Submit?

Nov 25, 2010

I have following model class:

public class WebModel
{
public List<ArticleModel> Articles { get; set; }
}
public class ArticleModel
{
public int ID { get; set; }
public double ValueParam { get; set; }
}

Then I have the controller with the two actions:

[Authorize]
public ActionResult Index()
{
WebModel model = new WebModel();
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
[Authorize]
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(WebModel model, string saveButton)
{
ModelValidation.ValidateWebModel(model, ModelState);
if (ModelState.IsValid)
{
return RedirectToAction("Create", "Article");
}
ModelConverter.ConvertToModel(model, controller);
return View(model);
}

And this is my view:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Web.Models.WebModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<%var controller = Session["controller"] as Web.Code.SessionController; %>
<%Html.BeginForm(); %>
<div>
<table width="100%">
<%foreach (var article in Model.Articles)
{%>
<tr style="text-align: right">
<td>
<%:Html.DropDownListFor(m=>m.Articles.FirstOrDefault(f=>f.ID == article.ID).ID, new SelectList(controller.CurrentProdukt.Articles.AsEnumerable(), "ID", "Name", article.ID)) %>
</td>
<td>
<%:Html.TextBoxFor(m => m.Articles.FirstOrDefault(f => f.ID == article.ID).ValueParam)%>
</td>
</tr>
<%} %>
</table>
</div>
<table style="width: 100%">
<tr>
<td>
<input type="submit" name="saveButton" value="Save" />
</td>
</tr>
</table>
<%Html.EndForm(); %>
</asp:Content>

If I press the submit button, I get to the second action method in the controller (the one with the HttpPost attribute). In this action, the object model itself is not null, but the "Articles" list inside is null.

After Upgrading / Getting Contains Is Not A Member Of System.array Error

Aug 17, 2010

I have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.

I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.

Here is my linqkit query:

Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))

Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.

My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.

AJAX :: AutoCompleteExtender - Cannot Refer To An Instance Member Of A Class / How To Fix Error

Dec 7, 2010

I am using the Ajax AutoCompleteExtender control, and employing a public shared function to act as a web service without actually creating a web service. This approach works perfectly, however I would like to take this one step further and filter my query from a drop down list, however I am unable to accomplish this. Whenever I attempt to reference the drop down list from within the public funtion, I get:

"cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class."

I have found very limited documentation on resolving this error. Pretty much every solution includes removing the shared reference instead of handling it.

When I remove the Shared reference and just make it private, the AutoCompleteExtender ceases to function completely (i.e. functions a a regular textbox). Here is my code:

If you notice that I am not referencing the @YRQ parameter in my query, that is intentional. I will replace the subquery with that parameter when I am able to get this working.
