my query
var data =
from b in re.wccs
join t in re.targetxyz on b.xyz equals t.dname
select new val { wcc = b, targetxyz = t };
return View(data);
my error
System.Linq.Enumerable+WhereSelectEnumerableIterator`2[db.Models.val,System.Int32]
i can load all the columns with sum but at the place of select command i get this error.
why any suggestion?
You will need to use First or Single to get that value, and possible some ordering on data (as not sure what you want to show here)
e.g.
#Model.Where(s=>s.wcc.xyz=="abc").Select(s=>s.targetxyz.wcc).FirstOrDefault()
#Model.Where(s=>s.wcc.xyz=="abc").Select(s=>s.targetxyz.wcc).SingleOrDefault()

I'm a beginner and I'm trying to write a Selenium web driver. I'm using eclipse and trying to locate a link available in next column. In each row I have different link. For example in my employee data table I have 2 columns and 10 rows in one page. The first column contains the name of person and second column contains its employee ID (ID is a hyperlink). I'm trying to select the hyperlink of any employee but I'm not able to do it.
I have below the HTML code and sample script.
<span id="37">
<div class="clear"></div>
<div id="FC_Schema.1021.WIP" type="DataCheckingList" name="FC_Schema.1021.WIP">
<input id="baseurl" type="hidden" value="/Web/" name="baseurl">
<input id="hdnDcCnt" type="hidden" value="13" name="hdnDcCnt">
<input id="PageNo" type="hidden" value="1" name="PageNo">
<meta content="width=device-width" name="viewport">
<style type="text/css">
<div id="DataCheckingLoad">
<div id="SupplyChainTabs">
<div id="gbo" class="InnerAlertsTabs">
<table id="one" class="draggable" width="100%">
<thead>
<tbody>
<tr>
<td valign="top" align="center">
<td valign="top">
<td valign="top">
<a onclick="return ButtonClick(this,'TxnyD.Communities.2.1','Org.2000476_Product.THQS|SMS|Questionnaire.WIP_Questionnaire_TxnyD.Communities.2.1_THQS_TxnyD.Operationaloffice.1.2');" href="#f">Axiom
Process LLC</a>
<div class="country-name">
<div class="CompanyInfoContactLinks">
</td>
<td valign="top">
THQS
<div class="clear"> </div>
<a id="Org.2000476_Product.THQS|SMS|Questionnaire.WIP_Questionnaire_TxnyD.Communities.2.1_THQS_TxnyD.Operationaloffice.1.2" onclick="RedirectToQuestionnairePage(id)" href="#">THQS</a>
<div class="clear"> </div>
</td>
In the above code first column contains company name i.e "Axiom
Process LLC" and second column contains company subcription name i.e."THQS". I have to select the THQS link of company "Axiom Process LLC"
Selenium script designed for it as below
public static void main(String[] args) throws Exception {
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get("http://XXX.XXX.XXX.XXX/Web");
Thread.sleep(1000);
driver.findElement(By.xpath("//input[#id='UserName']")).sendKeys("Gbouser.1");
driver.findElement(By.xpath("//input[#id='Password']")).sendKeys("****");
driver.findElement(By.xpath("//input[#name='Login']")).click();
driver.findElement(By.xpath("//a[contains(text(),'Task')]")).click();
driver.findElement(By.xpath("//a[contains(text(),'Data Checking')]")).click();
driver.findElement(By.partialLinkText("Axiom")).findElement(By.xpath("//a[contains(text(),'THQS')]")).click();
}
So basically these are dynamic tables and each time it will have different records. How can select the link available in column?
I also tried below script as well:
driver.findElement(By.name("*[id^='CLS'][id$='Demolition Limited']")).findElement(By.xpath("//a[contains(text(),'THQS')])[3]")).click();
welcome to Stackoverflow. Before answering your question, just a few pointers. Think that you had a downvote 'cause you didn't format your question well. Otherwise a perfectly legal question, and you would receive help much earlier.
Secondly, don't ever put the real Web site address, username and password :). I was able to login, and understand exactly what you need, but a malicious guy could do bad wonders there.
To answer your question, instead of the line that is causing you problems, try this
Thread.sleep(3000);
TablePageObject tablePageObject = PageFactory.initElements(driver, TablePageObject.class);
tablePageObject.clickLink("Axiom");
Where TablePageObject is
public class TablePageObject {
private WebDriver driver;
#FindBy(css = "table tr")
private List<WebElement> allTableRows; // find all the rows of the table
public TablePageObject(WebDriver driver) {
this.driver = driver;
}
public void clickLink(String companyName) {
for(WebElement row : allTableRows) {
List<WebElement> links = row.findElements(By.cssSelector("a"));
// the first link by row is the company name, the second is link to be clicked
if (links.get(0).getText().contains(companyName)) {
links.get(3).click();
}
}
}
}
An explanation, TablePageObject class will be your programmatic handle for the dynamic table you're trying to control. It follows a page factory pattern of selenium, which I heartly recommend, and you can learn more here https://code.google.com/p/selenium/wiki/PageFactory
It basically keeps a collection of rows of your table, which more or less looks like:
<tr>
<td valign="top" align="center">
// irelevant
</td>
<td valign="top">
// irelevant
</td>
<td valign="top">
<a>Axiom Process LLC</a>
<a>company details</a>
<a>web details</a>
</td>
<td valign="top">
<a>THQS</a>
</td>
<td valign="top" align="center" style="display: none">
// irelevant
</td>
<td valign="top">
//irelevant
</td>
<td valign="top">
// irelevant
</td>
<td valign="top">
</td>
<td>
</td>
</tr>
You collect all the links from the table, check the company name against the first link, and if matched, click the fourth link,
Hope it helps, best,

I am testing out angularJS.
In app.js I have
function ListCtrl($scope, Restangular) {
Restangular.all("employee").getList().then(function(employee) {
$scope.employee = employee;
console.log($scope.employee.emp);
});
}
and in html I have
<table class="table table-striped table-condensed">
<thead>
<tr>
<th>Emp No</th>
<th>Name</th>
<th><i class="icon-plus-sign"></i></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="employee | filter:search | orderBy:'ename'">
<td>{{employee.empno}}
</td>
<td>{{employee.ename}}</td>
<td>
<i class="icon-pencil"></i>
</td>
</tr>
</tbody>
</table>
Problem I am facing is there are empty rows being displayed with no data being displayed.
What could be the reason for this?

Based on the JSON you've included it looks like $scope.employee should contain a one key called "emp", which is what you print to the console. You might need to change your ng-repeat to work with that.
Also, I'm unfamiliar with the form of your ng-repeat expression. I believe they are supposed to follow a form similar to "something in somethings" so in this case instead of just employee you may want that to be employee in employee.emp.
In a more general sense, the Angular Batarang plugin for Chrome is infinitely helpful for solving these sorts of problems.
Is it possible to create table using Repeater control which has rows wrapped in ItemContainer controls? Something along the line:
<table id="products">
<thead>
<tr>
<td>Name</td>
<td>Description</td>
<td>Type</td>
<td>Billing Periodicity</td>
<td>Average Life Time (in months)</td>
<td>Is default</td>
</tr>
</thead>
<tbody id="tableBody" data-win-control="WinJS.UI.Repeater" data-win-bind="winControl.data: products">
<tr data-win-control="WinJS.UI.ItemContainer">
<td data-win-bind="textContent: name"></td>
<td data-win-bind="textContent: description"></td>
<td data-win-bind="textContent: type"></td>
<td data-win-bind="textContent: costPeriodicity"></td>
<td data-win-bind="textContent: averageLifeTime"></td>
<td data-win-bind="textContent: isDefault"></td>
</tr>
</tbody>
</table>
Given example throws exception at runtime:
Unable to get property 'children' of undefined or null reference
I' d like to use ItemContainer's functionality to make table rows clickable. Is my approach to the issue invalid? Is ItemContainer control wrong to use in that scenario?
Side note - if I apply ItemContainer control to table cells (td), evertything runs smoothly (they behave like windows8 - like clickable objects).
You incorrectly declared data source for repeater, it should be declared as win-options not -win-bind, when you change it to:
<tbody data-win-control="WinJS.UI.Repeater" data-win-options="{data: products}">
it should work with no problems.
I'm trying to dynamically update a HTML table via Comet. I've got something like the following:
class EventsComet extends CometClient[Event] {
def server = Event
def render = {
println("Binding on: " + defaultHtml)
data.flatMap( event =>
bind("event", "name" -> event.name.toString, "date" -> event.startDate.toString)
)
}
}
And:
<lift:comet type = "EventsComet">
<table>
<thead>
<tr>
<th>Name</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<tr>
<td><event:name />Test Name</td>
<td><event:date />Oct. 25, 2012</td>
</tr>
</tbody>
</table>
</lift:comet>
This prints out the entire table over and over again, one for each event rendered by EventsComet. The println statement outputs the entire table node.
So I tried variations:
<table>
<thead>
<tr>
<th>Race</th>
<th>Track</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<lift:comet type = "EventsComet">
<tr>
<td><event:name />Test Name</td>
<td><event:date />Oct. 25, 2012</td>
</tr>
</lift:comet>
</tbody>
</table>
As expected, the HTML5 parser strips out the [lift:comet] tags and no binding occurs.
So I tried switching the rows to:
<tr lift:comet = "EventsComet">
<td><event:name />Test Name</td>
<td><event:date />Oct. 25, 2012</td>
</tr>
...as is shown in a snippet example here, but with this syntax my CometClient is not being instantiated at all.
Can anyone advise on the proper syntax?
EventsComet itself works fine; it can keep lists of events up to date without problem. I only run into issue using tables (and presumably other highly-nested structures I've not tried yet?).
Thank you. This is all rather frustrating for such a simple problem, and makes me want to just start implementing my templates in a strongly-typed templating language instead of using bindings.
The proper syntax seems to be:
<tr class="lift:comet?type=EventsComet">
<td><event:name />Test Name</td>
<td><event:date />Oct. 25, 2012</td>
</tr>
From this thread:
https://groups.google.com/forum/?fromgroups=#!topic/liftweb/NUDU1_7PwmM
Sometimes I'm getting duplicate rows (inserted above the table header at that), but I'd imagine this is related to my comet actor itself.
