C# - Abort Sorting In Datagridview When Row Has Been Edited?
Dec 2, 2010
I have datagridview with 2 columns. SortMode of first is set to Automatic.
In this grid is a lot rows, and when I change value in the row, for example from xyz to abc I still in position where this row WAS. Edited row jumps to top.
I want to abort this automatic sorting and I want call sorting by left click on column. Be
I found some solution (code below + I set SortMode to Programmatically), but my row still jumping :/ Has anyone solution to tackle with this issue?
I have two grid view controls one is temporary and another is simple grid view control.in the simple grid view control it includes the edit button on its command name edit i want to edit this grid and also to show values in the temporary grid. How it can be possible?
using the latest bits for MVC 3 i'm looking at the code for a Controller (Northwind products), specifically my 'Edit'Action.
there are two methods, one for diplaying the item to edit, and one for posting back changes made on the UI.
My question is : how do i get a reference to the currently edited product. The method takes 2 arguments; the id of the product and a formcollection which is a dictionarly of product proerties by the looks of it. mvc 2 had slightly differentt arguments compared to mvc 3 beta.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
what are the possible cases/causes for a thread abort exception? and how can we re-produce the same scenario if such exceptions can only be found on live production environment?
is it possible to access session variables when such exceptions occur or will session variables also get flushed and no longer be available? if we are able to manage/handle such exceptions, then will our application will continue to provide us a log for success/failure case of any particular task/process from where it was stopped?
I've got this ActionFilter, and it's suppose to end the connection immediately and return a 401 Unauthroized:
public class SignInRequired : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext)[code]....
I learned how you can cancel the action from executing by setting 'context.Result = new EmptyResult()` here, but I'm not sure if this is the best way to flush the response and close the connection.
I have a common base class from which all my ASMX webservice classes will inherit. In the constructor, I want to do some common authentication checks; if they fail, I would like to halt processing right away (subclass's code would not get executed) and return a 401-status-code response to the caller.
However, the common ASPX-like ways of doing this don't seem to work:
Context.Response.End(); always kicks back a ThreadAborted exception to the caller, within a 500-status-code response. Even if I explicitly set Context.Response.StatusCode = 401 before calling End(), it is ignored. The result is still a 500-response, and the message is always "thread-aborted-exception". MSDN suggests I use HttpContext.Current.ApplicationInstance.CompleteRequest() instead. However, this does not stop downstream processing: my subclass's functions are still executed as if the constructor had done nothing. (Kind of defeats the purpose of checking authorization in the constructor.) I can throw a new HttpException. This is a little better in that it does prevent downstream processing, and at least it gives me control over the exception Message returned to the caller. However, it isn't perfect in that the response is still always a 500. I can define a DoProcessing instance var, and set it to true/false within the constructor. Then have every single WebMethod in every single subclass wrap its functionality within an if (DoProcessing) block... but let's face it, that's hideous!
Is there a better / more thorough way to implement this sort of functionality, so it is common to all my ASMX classes?
edit: Accepting John's answer, as it is probably the best approach. However, due to client reluctance to adopt additional 3rd-party code, and some degree of FUD with AOP, we didn't take that approach. We ended up going with option #3 above, as it seemed to strike the best balance between speed-of-implementation and flexibility, and still fulfill the requirements.
AjaxControlToolkit.ToolKitScriptManager.OnInit() throws thread abort exception for every aspx page. I have an asp.net 2.0 Ajax application, where I have set the following properties of ToolScriptManager on my pages.
I have this configuration on all the aspx pages in my application. When I checked the .NET CLR exception Performance counter I figured out a large number of exceptions, mainly one exception per page load is occuring. On running windbg I was noticed that
AjaxControlToolkit.ToolKitScriptManager.OnInit() has the following code block which is getting executed. The OutputCombinedScriptFile() returns true. But since I am setting my controls on DesignTime still designmode is set to false for toolkitscriptmanager.
if (!DesignMode && (null != Context) && OutputCombinedScriptFile(Context)) { // This was a combined script request that was satisfied; end all processing now Page.Response.End(); }
I am not sure if this is a reported bug or even a bug with ajax, but this is causing havoc in my load test results as I have around 3 hundred thousand HTTP requests to be handled per day out of which 80% are aspx page requests resulting in a large number of threadafbortexceptions, thus affecting the performance.
Moderators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction 2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.

In VWD, we can customize-edit-command to your heart's content. But there is none for what I used to get in NetBeans or Eclipse: go to the last edited position (after 5 minutes of search for the correct spelling of some name in the page).I know there is Navigate Back, but I often need to do click [Navigate Back] 10 times to get to 'last edited line'.
It would be nice if I can navigate through the 'green bars' (Yes, it is very difficult to find out what are green bars, once you found out, you want to be able to visit each of these using next or prev).
Also where is the documentation or help ofr each of the some 50 edit commands such as 'go to Reference'.
I am binding the ReorderList in my code behind file. I am not using a DataSource Control like SQLDataSource etc. How will I capture the values edited, in my ReorderList1_UpdateCommand(). In GridView we can use something like
(TextBox)GridView1.Rows[e.RowIndex].Cells[4].FindControl("txtMyTextBox").Text. Is there anything similar in a ReorderList?
i have a problem with detailsview as below, when user click on btnEdit, it will call detailsview.changemode(edit) and then allow user to enter data into the textbox, after that user will click on btnsave and then to read the value from txtname and process the value. my question is how do i get the value from txtname? i dont want to use any datasource component and i have tried call the DetailsView1.FindControl("txtname") and it returned txtbox with empty text.
Is this even possible? I'm trying to pass the DataKeyName (Primary Key) of my master gridview to an embedded child gridview, using a select controlparameter of the SQLDataSource control.
I have a GridView with drop down boxes that are always in edit mode, and what I want to do is when the user sets a value in one of the drop downs I want to set the value in all of the drop downs BELOW that one (if they are not currently set) to the same value. However, the RowEditing and RowUpdating events never fire because techncially I'm not editing or updating the row.
Here is what I'm wanting to do, something along these lines:
[Code]....
Here is what is corrently working, but it sets the values both above and below the current row:
