I'm trying to print a GWT widget as follows,
String html = DOM.getElementById("id").getInnerHTML();
Print.it(html);
I'm not getting the entire html content of the widget. So i'm not able to print the expected result.
Can you help me? Or tell me the alternative way of printing a particular GWT widget from the view.
Thanks in advance,
Gnik
Well, it should print the HTML code. Calling DOM statically may generate 2 problems for you:
The ID you are trying to use isn't the right one. There is another element with the same ID and you are retrieving the element for that ID.
The ID you are using doesn't exist, as a framework may be changing this ID.
You can try to retrieve the HTML code with this widget.asWidget().getElement().getInnerHTML();
That should give you the correct HTML representation of the widget.
And make sure you are calling those methods after the elements are loaded (onLoad()) into the document, or you may recieve a JavaScriptException due to the element being null (check here for more info).

using Ajax I filled Country, State and city dropdownlist. On land change state is filled and on state change city is filled properly.
Then when I try to save page I face this :Invalid postback or callback argument.
Searched and found out that this is due to change in ddl.selectedvalu change from initial value that is assigned by asp.net.
Now my question is that how can I let asp.net know that the new ddl value is valid?
Thank you.
In many pages it is recommended to use EnableEventValidation="false", but I prefer not to use it.
Some say that use Render and add value to notify .Net like this:
protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
ClientScript.RegisterForEventValidation("ddlLanguages ", "English");
ClientScript.RegisterForEventValidation("ddlLanguages ", "Tamil");
ClientScript.RegisterForEventValidation("ddlLanguages ", "Hindi");
base.Render(writer);
}
but how to use it? where to put it?
for a better understanding I put here a sample code including Database script :
hesab20.com/DownLoad/Ajax.zip
in this sample Javascript is used to fill drop-down list . But when click button is executed and a post back occur, error happen.
Please help if you have experience with this.
Regards.
Please run the sample code and change the drop down lists , automatically the other is filled , meaning that list item text and value is completely changed. finally click button for a post back.
you must see that error happens:
Invalid postback or callback argument. Event validation ....
and note : EnableEventValidation="true"
Thanks
I need to find any extra links and print them out. I started by doing:
get_xpath_count('//li/a')
and comparing it to the size of an array that holds the name of all the links for the sidebar. When the count is too high/low, I need to print out all the extra/missing links. I would like to make a list of the names so I can compare it to the array. I've tried a few things like get_text('//li/a'), which returns the name of the first. get_text('//li/a[1]) does the same, but any other index returns nothing.
Any ideas? Also, I need the name that's displayed on the link, not the actual href.
Edit* Also, i'm pretty new to selenium and Xpath. Please let me know if there's info I let out that is needed, or just any suggestions towards thew way I'm going about this.
I have been able to get this to work using CSS element locators. Since I use CSS selectors far more often than Xpath, I find it easier to always use them with Selenium as well.
$selenium->get_text("css=li a:nth-child(1)")
$selenium->get_text("css=li a:nth-child(2)")
$selenium->get_text("css=li a:nth-child(...)")
$selenium->get_text("css=li a:nth-child(n)")
Use:
(//li/a)[$someNumber]
this will get you the text of $someNumber-th //li/a in the XML document.
In order to know what values to use to substitute the $someNumber with, you need to know the total count of these elements:
count(//li/a)
This is in JAVA. You can use the same concept in perl
int totCountInPage=selenium.getXpathCount(//li/a);
for(int count=1;count<=totCountInPage;count++)
System.out.println(selenium.getText("xpath=//li[count]/a"));
This should print text inside the anchor links under all li tag.
My SSRS report contains 7 input parameters and while running my report the size of the parameter(i.e. length) is increasing.
One of my input parameter(drop down list) may contain 100 characters so the size is not constant but i want to place all parameters in 2 lines or 3 lines(in a row).
Now it is coming 2 parameters per a row
Please advice
As gbn indicates, it's not easy to change the built in report server method of presenting the parameters. SSRS likes to always use two parameters per line, presented in the order that they exist in the report (which must match the dependency order.)
So the alternatives that gbn mentions: Both involve building a "Wrapper" application: some custom code or a web page that you can code however you like to get the parameters. Then you call Reporting Services, either in code or by passing a formatted URL with your parameters. The report can be displayed in a frame, new window, or passed as a stream to where ever you'd like.
The URL access is pretty straightforward and reliable: I often use it either by hand (to create "favorites") or in code.

For what you are looking for, these might be more work than you expected, but they will be extremely flexible for your interface.

You can certainly do that, just right click on the RDL file in the solution explorer and select view code. then move the XML tags named <ReportParameter Name="Nameofparameter"> under <ReportParameters> according to where ever you want to position. And then save it. thats it!!!
The report parameters are kind of floating in values of 2, so if u have 4 report parameters then it will be shown as 1,2 next line 3,4. Best of luck!!
Use ASP.NET for the paramaters and a ReportViewer control or URL access to render. Seriously.
I don't know of any option to present parameters any way other then the default
I believe you could try using jQuery. The report parameters are rendered in a table under a div tag with class sqlrv-ParameterContainer. Write a jQuery or JavaScript function that will extract the full innerHTML from this div ie. the table content and then extract the table row information like the <label> or <input> tags.
Create your desired table structure with <table><tr><td>{extracted sections}</td><td></td></tr></table> or leave it to your requirement...
Then just append this new HTML structure in place of the original default structure.
In jQuery it will be like
$(".sqlrv-ParameterContainer").html();
which will give you the entire table structure that comes inside the parameter. Use XML parsing and get the input controls and all. Extract these controls as-is, don't change anything.
$(".sqlrv-ParameterContainer table").remove(); // it will remove the SSRS rendered default table from DOM
$(".sqlrv-ParameterContainer table").appendChild('<table><tr>......</tr></table>'); // Append your custom html structure here....
This was something that came to my mind quickly... I would suggest you test it... :)
This doesn't help the OP with SSRS-2008 but in case it helps others - Microsoft have improved this in SSRS 2016 - parameters can now be easily managed via the GUI in Report Builder / Visual studio:

I already know how to parse XML Elements that contain content (<this> Content </this> in Objective C but I am currently using a web service that returns the content I need in between two closed elements (<begin-paragraph/> The content I need <end-paragraph/>) I have been looking online for any examples of anyone else doing this, but I could not find anything. If anyone knows how to read between the two empty elements and would care to share, I would appreciate that very much.
I have to say I regard that as an abuse of XML.
But I've checked and sadly it is well formed so NSXMLParser (which I assume is what you are using) should be able to cope with it.
You basically need to check which element you are in by handling the start element and end element events in your NSXMLParserDelegate. Then after receiving the –parser:didEndElement:namespaceURI:qualifiedName: message for begin-paragraph grab all the text you receive in -parser:foundCharacters: until you receive –parser:didStartElement:namespaceURI:qualifiedName:attributes: for end-paragraph
I don't know what the DOM conformance on the iPhone is like, but the general procedure would be:
Navigate to <begin-paragraph /> in your DOM.
Get the next sibling of that node. That is the content you need. (Node::nextSibling property)
If there are other elements in there that you want, keep collecting them by the same method, until you reach <end-paragraph />
I want get html id of input field & icon field of a TextItem widget, how can i do this ???
(no getId methos is available for TextItem widget & seems that setAttribiute("id", "foo") has no effect)
since everything is on a single page, i wouldn't dare to set any IDs yourself, the probability that you create two items (by mistake) with the same id is quite high.
why would you need it anyway?
you may get the html element by name
textItem.setName("foo");
DOM.getElementsByName("foo")
