I have a search function in my application which gets me customers. Therefore I got an complex "Customer" object. So the list is of type Customer.
This list is filled properly on button click. But when I want to clear the list on Button click a error is thrown in my browser console:
TypeError: Cannot read property 'length' of undefined
What is the correct way to clear a list of complex object? Currently I am using a General Service which does the following:
tw.local.searchResults = new tw.object.listOf.Customer();
This throws me the above error.
Any Ideas?
Do a check on the length of the list such as if its length is not undefined and then read the results inside the if-block.
I am new to ASP.Net DataGrid, I have a grid which has linkbutton on each row!!
On Itembound event I am getting the object which I am binding to the grid!! On button click, I need to send this object data to webservice!!
How do I get object on button click? CommandArgument is of string type, is there a way to pass object to CommandArgument?
No, there is no such way. This object basically exists only during the data binding period. And button click handling happens on a next request, so this object does not even exist anymore.
Your options are:
Best and most common. Pass the object id as an argument, and in the button click handler do a query (to the database, I presume) to get the object by id.
No so common and weird. Implement serialization and deserialization of your object. This way you can pass the whole serialized object string as an argument, and deserialize it on button click.
I have followed this tutorial for the most part to explain what I am doing. http://www.asp.net/data-access/tutorials/creating-a-business-logic-layer-vb
What i need to do is figure out the best way to approach to be able to update my formview. I do not understand what the tutorial is trying to explain to me so i tried it the way i have updated a gridview before. But I am receiving "No parameterless constructor defined for this object." I tried to debug and view the callstack but it does not really tell me much.
I have my sql stored procedure to update which when executed works fine.
I also have another class in which i reference the application details class
applicant.vb
This is the code in order for when you click the view details link on the gridview it passes you off to another page that shows that applicants details it is within the same applicant.vb class
I am trying to update using the following method on the .aspx page but i receive the following error "No parameterless constructor defined for this object."
Memberdetails.aspx
Without knowing which line of code is causing that error, I can't say for sure, however, my guess is that your error is on this line of code.
_applicantadapter = New applicantTableAdapter
Put an open parentheses after applicantTableAdapter to see the different constructor signatures available to you for that type. I bet you'll see none of the options allow no parameters.
That error means that the object type you are trying to instantiate requires that you include parameter(s) (and you are not).
I am getting these weird runtime errors. I am using Flex 3.5 SDK with flash player set to 10.0.00.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.flash::UIMovieClip/removeFocusEventListeners()[E:\dev\flex\sdk\frameworks\projects\flash-integration\src\mx\flash\UIMovieClip.as:2368]
at mx.flash::UIMovieClip/focusOutHandler()[E:\dev\flex\sdk\frameworks\projects\flash-integration\src\mx\flash\UIMovieClip.as:2411]
I get this errors when I click on any other control in a popup. I am using buttons, textarea,textinput,and a list. I dont know how to fix this ... It would be great if someone pull me out this problem?
Without the code it's gonna be hard to pinpoint. This error could occur if you are trying to 1) access the property of an object that hasn't been created by the time the focus out handler is called, or 2) access the property of an object that ins't referenced in the focus out handler.
Make sure any non-local variables in the focus out handler reference an object that has been created somewhere in your application before the call to the focus out handler. Also, make sure a reference to each object gets passed into the focus out handler by declaring those variables globally, or passing the object to the function as a parameter.
Post the code if you can.
Seems you have to remove focus from your UIMovieClips before removing them from the stage:

Or just target flash player 10 where this bug is fixed.
Add this code to the top of any function that may remove a UImovieClip from the display list:
if (stage)
{
stage.focus = null;
}
I have created a Telerik report and I am setting the datasource on runtime to an object with some properties and a List. I am using the properties in the page and report header sections and i want to use the list as the details. Now the problem is binding to the List's item properties in the details section. I have played around with the expression builder and it seems that i should access the properties like this :
[=Fields.myList.Item.myProperty]
when i run the program i get a nice big red rectangle with the following error :
An error has occured while processing TextBox 'textBox28':Common Language Runtime detected an invalid program.
I have tried to change different variants of expression which also gives me other errors
[=Fields.myList.myPropery]
An error has occured while processing TextBox 'textBox28': The expression contains object 'myProperty' that is not defined in the current context.
The closest i have gotton was with the object it self, which outputs the object.toString()
[=Fields.myList]
I found a working solution although not what i was looking for, I created my own class with properties and made a List. I then retrieved the data from the db did the changes i wanted to do in the class and set the datasource of the report to the list. This is working quite well.
I struggled with this error:
An error has occured while processing TextBox 'textBox28': The expression contains object 'myProperty' that is not defined in the current context.
The solution I came up with was to make my model object inherit from List. For example:
public class MyReportModel : List<MyEntityDto> {
}
The look of the report wizard makes it seem like this isn't necessary, but I found no other way around this error.
