For the life of me, I can't figure out what the problem is with this:
tempData= from a in dx.SomeTable select a;
string searchField="ItemName";
string searchString="BoxPkg";
object[] parameters=new object[]{searchField,searchString};
tempData = tempData.Where("@0 like @1", parameters);
I get this error " {"Expression of type 'Boolean' expected"} "
I am getting an Identifier expected error under the closing tag of this expression but the code seems to be ok.

<asp:Button ID="btnDetail" OnClick=<%#"javascript:return Detail(DataBinder.Eval(Container.DataItem,"Description"));"%> runat="server" Text="View Detail" />

I'm having issues when trying to run my web app. I'm getting an expression expected error at runtime on the portion of my code that is designed to retain the screen position of multiple drag panels.
Code:
var target = $this).attr("id");
should return the id of the uniquely named panel so it can be used later in code to identify the _DragPanelExtender.BehaviorID
Code:
$find('<%=' + target + '_DragPanelExtender.BehaviorID%>').set_location(new Sys.UI.Point(parseInt(temp[0]), parseInt(temp[1])));
I haven't been able to verify if the dragPanel's id name is being used, it just errors out here. In the following code, I am attempting to preserve the position of multiple dragPanel's after postback?
Code:
function pageLoad() {
//get element id name of button clicked
var target = $(this).attr("id");
// call the savePanelPosition when the panel is moved
$find(target).add_move(savePanelPosition);
var elem = $get("<%=HiddenField1.ClientID%>");

In my VB.Net code I am using boolean type and it is later stored through a stored procedure to a MS SQL database table. I have so far allways been using "int" as the column type in database table because there is no Boolean type to choose from when designing the columns of a table in the MS SQL Express? Is it correct to use the column type int for storing Boolean values?
View 2 RepliesI have a datagrid control, the first column is Revno, currently presenting info in linkbutton. i want to do a condition based on another field docid, which gets true or false value from database. if true then present Revno in linkbutton otherwise show the revbnno just as a label., thatway users does'nt have ability to clickit.
<ItemTemplate>
<asp:LinkButton ID="lblRevision" runat="server" CssClass="Textboxes" Text='<%# DataBinder.Eval(Container.DataItem, "RevNo")%>' CommandName="FileDownloadRecord"></asp:LinkButton>
</ItemTemplate>
this docid field has flag true or false.
if true meaning show the revno as LinkButton, otherwise show the revno as label.
GetDocdetail(DataBinder.Eval(Container.DataItem, "Docid")
on the codebehind side i can use this function.
Public Function GetDocdetail(ByVal DocID As boolean) As String
If DocID = "true" Then
Else
End If
End Function

I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names. So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.
I am writing a bit of code to store about 100 (yes/no) answers about hotels. I have about 7000 records so I need to try and get this right the first time.At the min I have 4 * int32 values stored in SQL and I use a structure containing names boolean values like swimming pool, bar etc etc. In my BLL I have a method that tests the bits in the int 32 and sets the boolean value to try or false.
I have not had any problems with this way, but was thinking about the performance as this would currently have with about 100 if statements in the BLL to set all of the boolean values.The only other ways as I see it are..
1) have 100 boolean columns in the sql table, which I feel would be messy.
2) to have all the int32 sql values populate another text field that is stored in the DB so that the int32 value creates a text string when the hotel owner populates the click boxs in the first place. - then I just display the text value which would have been created something like "pool, bar" My way of lots of ifs does work, I was just worried about the performance

I have a XMLDataSource somewhat like:

I am storing these in a asp:formview. I am able to store author and publication values but not sure how can I store the value of book/name based on some condition? Actually I just want to use condition that I need to store the value of "name" if "genere=Romance". something like this. I tried using XPath expression bookstore/book/genre[. ='Romance'] but not sure how to access the value of tag. Checked the following resource:

I am trying to call a Page Method using AJAX.
See the code
<asp:Button ID="btn_upload" runat="server" CssClass="btnEffects" Text="Upload"
onclick="btn_upload_Click" OnClientClick="return Validate();" />
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript">
function Validate()
{
var filename = $get('<%= txt_filename.ClientID %>').value;
PageMethods.IsValidFile(filename,OnSuccess, OnFailure);
// IsValidFile is a Page Method of bool return type
}
function OnSuccess(result)
{
if ( !result)
{
alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist');
return false;
}
else
{
return true;
}
}
function OnFailure(error)
{
}
</script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
I have a large existing stored procedure who's interface I cannot change that has several parameters of type boolean. ODP.NET doesn't support a boolean type and I get an error when trying to access this proc via .NET using a different data type.
