Literally the first result on Google for "html div onblur":
For blur event to fire on an element, the element needs to receive focus first. But <div> elements do not receive focus by default.
You can add tabindex="0" or contentEditable to your div so it will receive focus.

ok but focusout event fire without set tabIndex=0 to div element , and this means that div has focus in this scenario!!!!
i set "tabIndex=0" to div element for fire onblur and doesn't work!
|

The blur event fires when focus is lost. By default, a div element cannot have the focus in the first place so it can not be lost.
If you give the div a tabindex attribute, it will be able to accept focus:
<div id="divid" tabindex="0">Test content here</div>
then attach focus and blur event handlers:
document.getElementById("divid").onfocus = function() {
alert('focus is hit');
}
document.getElementById("divid").onblur = function() {
alert('blur is hit');
}
Hope this helps !!

Hopefully, I am posting on correct forum.
I have a report with a parameter called loc.
The intended purpose of the report is to allow users to select a location from the dropdownlist and then records associated with that location are displayed to the users.
The dropdownlist is getting populated with values just fine.
However, when I select a location from the dropdownlist, I get an error that says:
Value cannot be null. Parameter name: reportParameters
Everything works fine when I pass a value as textbox but not as dropdown.
Any ideas what I am doing wrong?
Below are relevant code.
'---Dropdownlist control
<asp:Panel runat="server" ID="pnlLoc" Font-Names="Calibri" BorderStyle="Solid" BorderWidth="1" Style="margin: 0 auto; width:300px;">
<table>
<tr>
<td>
<asp:Label runat="server" ID="lblLoc" Text="Location: " />
</td>
<td>
<asp:DropDownList runat="server" ID="ddLoc" DataSourceID="dslocator6" AutoPostBack="True">
</asp:DropDownList>
</td>
</tr>
</table>
</asp:Panel
--Report viewer control
<rsweb:ReportViewer ID="ReportViewer1" runat="server" AsyncRendering="true" SizeToReportContent="true" Font-Names="Arial"
Height="675px" Width="750px">
<LocalReport EnableExternalImages="true" ReportPath="">
</LocalReport>
</rsweb:ReportViewer></center>
<asp:ObjectDataSource ID="LOC" runat="server" SelectMethod="GetData" TypeName="ManageReportsTableAdapters.searchBylocationsTableAdapter">
<SelectParameters>
<asp:ControlParameter ControlID="ddLoc" Name="Location" DefaultValue=" " />
</SelectParameters>
</asp:ObjectDataSource>
--This code populates the ddLoc dropdownlist
Protected Sub btnLoc_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnLoc.Click
ReportViewer1.LocalReport.ReportPath = ""
pnlLoc.Visible = True
which.Value = "P"
dslocator6.SelectCommand = "SELECT location FROM Locations ORDER BY [location]"
ddLoc.DataTextField = "location"
ddLoc.DataValueField = "location"
End Sub
Sub Run_Report(ByVal sel As String)
ReportViewer1.Reset()
ReportViewer1.LocalReport.DataSources.Clear()
Dim params(0) As ReportParameter
ReportViewer1.LocalReport.DataSources.Add(New ReportDataSource("locs", LOC.ID))
ReportViewer1.LocalReport.ReportPath = "locations.rdlc"
ReportViewer1.LocalReport.Refresh()
params(0) = New ReportParameter("loc", sel, False)
ReportViewer1.LocalReport.SetParameters(params) '<-- error points to this line
End Sub
I have been stuck on this for two days. Your assistance is greatly appreciated.

This means sel is null. If you debug you should find the issue.

<asp:DropDownList runat="server" ID="ddLoc" DataSourceID="dslocator6" AutoPostBack="True">
</asp:DropDownList>
in your dropdownlist add listitems
<asp:listitem value="location">Location

Hi All, i'm after a bit of advice on the homepage of my app there is one particular section (Repeater) that queries the DB to provide a high level overview of the latest version of an application. Loading the data into this repeater is having an impact on the load time of the homepage so my thought on this is to is to add a checkbox to the page and on the initial page load do not populate the repeater but if the user checks the checkbox to display the data then go an query the DB to populate the repeater. Aside from only loading this data on request what other way could I control the populating of this repeater so that is not impacting performance?

AM trying to integrate an online payment system, where the secure payment gateway will send a notification to a specified URL on my site - I have given a generic handler (.ashx) address. I can read the data they send (it's a simple POST), but they require that I send back:
a notification with a response of: "HTTP/1.1 200 OK".
I am not sure what they want... Is a simple
context.Response.ContentType = "text/plain"
context.Response.Write("HTTP/1.1 200 OK")
enough? Perhaps necessarily preceded with
context.Response.StatusCode = 200
?
Or is something more sophisticated required, along the lines of
Dim req As System.Net.HttpWebRequest = System.Net.WebRequest.Create("https://secure-gateway-url")
req.Method = "POST"
req.ContentType = "application/x-www-form-urlencoded"
req.Accept = "HTTP/1.1 200 OK" ?????
req.Headers .Add ( ?????
Dim param As Byte() = context.Request.BinaryRead(HttpContext.Current.Request.ContentLength)
Dim strRequest As String = Encoding.ASCII.GetString(param)
req.ContentLength = strRequest.Length
Dim streamOut As System.IO.StreamWriter = New System.IO.StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII)
streamOut.Write(strRequest)
streamOut.Close()
with what needed at the lines flagged ????
I’d be very grateful for any advice... thanks

Thanks - Google doesn't like me, I've decided  I did try and Google this myself....

I've written that before years ago, it was just easier for me to find it through search and post a link. Took me a while to find the right one.

You'll need to debug it and see what is happening.

Hi,
I have a pretty long and complex logic that needs to be run when the page loads.
The logic can't be changed.
What happens is that while the logic is executed, the page is of course stuck.
It involves drawing on the canvas element.
What options do I to work around this issue?
|
|
|
|
|
|
Thanks, I'll go over this info.
|
|
|
|
|
Thanks for your feedback.
I went through those links.
It looks something that could handle my problem but I need to draw a very complicated structure on the canvas + perform some interactions on it later and to do that, I need an access to the DOM + window which I don't
have through the web worker.
Any ideas how can I get around this?

I am writing to seek help, in regards to figuring out, how can I verify my email address using mx record. I am currently new into using MX records and so far, I have method which returns a mx record for specific domain (as shown below):
public static string mailMX()
{
string domainName = "#######.com";
string mail = "";
var response = DnsClient.Default.Resolve(domainName , RecordType.Mx);
var records = response.AnswerRecords.OfType<MxRecord>();
foreach (var record in records)
{
return (record.ExchangeDomainName).ToString();
}
return mail = records.ToString();
}
My desire goal is to create a method, which can verify the email address "info@reply.####.com" has a valid mx record and return the email address. I am slightly struggling in this area, as I am not to sure how to structure this task.
Any hints would be most appreciated. Thank you
