I added some javascript to fill in a dropdown and it works wonderfully. However, when I try to access the value in codebehind to submit the data, the value shows as null. (string strValue = ddlName.SelectedValue;).
[Code]....
in my proj i have a grid view which consists of name and droppown list as shown below:
<asp:GridView ID="gvJobs" runat="server" AllowPaging="true" AllowSorting="true" AutoGenerateColumns="False" OnRowDataBound="gvJob_RowDataBound" OnRowCommand="gvJobs_RowCommand" >
<Columns>
<asp:TemplateField HeaderText="Jobs" SortExpression="name" HeaderStyle-HorizontalAlign="Left">
[Code]....
when i click the dropdown list it is postbacking(since i made auto postback=true). on that time i am unable to get the selected value from dropdown list.
In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery. Don't know how to invoke the needed one based on the browsers javascript availability
View 1 RepliesI have created profile objects in my web.config file:
[Code]....
[Code]....
In all tutorials I am finding on the net it says in order to read/write from these properties I just need to use the syntax with C#:
Profile.Surname = "Surname";
But this does not work on my web site code when I'm using C# it underlines and recommends I change to System.Web.Profile.Surname (which I do) but then Intellisense and the compiler do not recognise Surname. What am I doing wrong? I am using Visual Studio 2010 and .Net V4.
I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.

In my current project (ASP.Net 2.0) I have a lot of web user controls, among them "Office.ascx". Office.ascx is loaded into another controls using this line:
guide_controls_display_Office o = (guide_controls_display_Office)LoadControl("Office.ascx");
The control I am loading it into has Office.ascx registered using this line:
<%@ Register TagName="office" TagPrefix="uc" Src="Office.ascx" %>
But I get this error upon launching the web page: Unable to cast object of type 'ASP.guide_controls_display_office_ascx' to type 'guide_controls_display_Office'. Why do I get this message? I can see that the first type has "ASP." in front of it. Is that normal?
I am getting an error when i call the button id which is inside GridView Item template.

I had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.

Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting

Dim dbDelete As New pbu_housingEntities

The specific line erroring out is: remove_bed.First.occupant = ""
on a server, I am trying to deploy a website. Originally, the page styles did not work and the some of the .gif and .jpg images didnt show up. I fixed the css problem by adding a http handler mapping through IIS. I tried the same thing to get the images to work but that didn't fix the problem. If the website was fully deployed im pretty sure the images would work so I dont want to change their paths (same with css). The handler mapping i added for css was for "*.css" of type system.web.staticfilehandler. This is the same type i tried for .jpg and .gif. I don't know specifically the purpose of system.web.staticfilehandler because msdn info is very short.
View 5 RepliesI have created a user control which is inside a folder called Controls and the class is a partial class which inherits from Web.UI.UserControl. Now from my page which is one level up I just try to access the method inside the usercontrol and so trying to cast it as the type of user control. But I get build errors. It just cannot recognize that class. I get Type not defined error. But at times it has recognized the class. Dont know why it does that.

View 4 Repliesas seen from the title my sql doesnt update the data that has been inserted by my function. But in my function it works perfectly as it returns '1' when i executenonquery. however it only works when i insert a record which has a date later than today's date. which is weird as there is no validation in that page and if there were to have a validation, it would not run the function.

I have a checkbox which in some cases may be disabled and checked using javascript, i.e:
var cbTest = document.getElementById("CheckBoxTest");

cbTest.checked = true;
However, when sending a postback, CheckBoxTest.Checked is false on the server side.
Is it possible to disable the checkbox and still have the server side recognize it as checked?
I receive this error message: LINQ to Entities does not recognize the method 'System.Guid GetUserId()' method, and this method cannot be translated into a store expression. This is my code:
DB.Users user = db.Users.FirstOrDefault(u => u.Id == BOL.GetUserId());
BOL.GetUserId() returns a GUID of the current logged-in user (and this works works).
How can I make this LINQ code line work? Or, what is the shortest alternative? In the mean time I found out that there is a difference between LINQ to SQL and Entities. I use Entities because of the TailspinSpyworks example... but my code is using LINQ to SQL. My current solution is to use a var:
var userId = BOL.GetUserId();
DB.Users user = db.Users.FirstOrDefault(u => u.Id == userId);
Is this a good solution? And, is the execution time of Entities faster than SQL?
