  • Which approach is better in term of saving the data? How to handle this?

    - by dewacorp.alliances
    Hi there I have Telerik grid within a Telerik grid. Due to I have a different view between insert and edit mode, so as per suggested I have to use UserControl instead. Inside this control, it could have another Telerik grid plus bunch of ASP.NET textboxes. This thing works well. My dilemma is this: Scenario 1: Handling the save in the user control - OnClick event I have a button to save this. I need to get the value of the "selected grid" so I am using this snippet below and again works well. foreach (GridDataItem dataItem in radgrdTariffNetworkDistributorRateItems.SelectedItems) { string ID = dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex]["SupplierRateItemID"].ToString(); } But then how do I get the id of the parent grid where this control sit? I use the following this event to save: protected void bttnNetworkTariffReviewItemInsert_Click(object sender, EventArgs e) the e of course not the right one though?!?!? GridDataItem parentItem = (GridDataItem)e.Item.OwnerTableView.ParentItem; string reviewID = parentItem.OwnerTableView.DataKeyValues[parentItem.ItemIndex]["ID"].ToString(); Scenario 2: Handling the save in the page instead (OnInsertCommand on the master grid) With this approach works well to get id of the grid etc BUT I am having a problem to get selected grid in the UserControl and plus couple controls value. How do I make this feasible? Logically, I should handle this at the user control level to save but again because the user control relying on the child grid I am having trouble to get this value. I am appreciated your suggestion.

  • Get all text between tags with preg_match_all() or better function?

    - by kylex
    2010-June-11 <remove>2010-June-2</remove> <remove>2010-June-3</remove> 2010-June-15 2010-June-16 2010-June-17 2010-June-3 2010-June-2 2010-June-1 I'm trying to find all instances that are between the <remove> tags This is what I have: $pattern = "/<remove>(.*?)<\/remove>/"; preg_match_all($pattern, $_POST['exclude'], $matches); foreach($matches as $deselect){ foreach ($deselect as $display){ echo $display."<br />"; } } This is what it returns: 2010-June-2 2010-June-3 2010-June-2 2010-June-3 Why is it doubling up, and how do I prevent that?

  • Is there a better way to detab (expand tabs) using Perl?

    - by Uri
    I wanted to detab my source files. (Please, no flame about WHY I wanted to detab my sources. That's not the point :-) I couldn't find a utility to do that. Eclipse didn't do it for me, so I implemented my own. I couldn't fit it into a one liner (-e) program. I came with the following, which did the job just fine. while( <> ) { while( /\t/ ) { s/^(([^\t]{4})*)\t/$1 /; s/^((([^\t]{4})*)[^\t]{1})\t/$1 /; s/^((([^\t]{4})*)[^\t]{2})\t/$1 /; s/^((([^\t]{4})*)[^\t]{3})\t/$1 /; } print; } However, it makes me wonder if Perl - the champion language of processing text - is the right tool. The code doesn't seem very elegant. If I had to detab source that assume tab=8 spaces, the code would look even worse. Specifically because I can think of a deterministic state machine with only 4 states to do the job. I have a feeling that a more elegant solution exists. Am I missing a Perl idiom? In the spirit of TIMTOWTDI I'm curious about the other ways to do it. u.

  • About presenter pattern in rails. is a better way to do it?

    - by Totty
    I have in my model: def presenter @presenter ||= ProfilePresenter.new(self) @presenter end The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view. So now i use them by doing this: Profile.presenter.get_link # or Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query

  • [C++] which is better, throw an exception or return nonzero value?

    - by xis19
    While you are doing C++ programming, you have two choices of reporting an error. I suppose many teachers would suggest you throw an exception, which is derived from std::exception. Another way, which might be more "C" style, is to return a non-zero value, as zero is "ERROR_SUCCESS". Definitively, return an exception can provide much more information of the error and recovery; while the code will bloat a little bit, and making exception-safe in your mind is a little difficult for me, at least. Other way like returning something else, will make reporting an error much easier; the defect is that managing recovery will be a possibly big problem. So folks, as good programmers, which would be your preference, not considering your boss' opinion? For me, I would like to return some nonzero values.

  • How can I know which website the member has visited previously?

    - by Tom
    So, I can use getenv('HTTP_REFERER') to get an URL which the member has visited previously, but it works only if it's the same website. I want this: for example. the member firstly visits google.com then goes to my website. I want to show him, that previously he visited a google.com website. How can I do it if it's possible?

  • MySql: Is it reasonable to use 'view' or I would better denormalize my DB?

    - by Budda
    There is 'team_sector' table with following fields: Id, team_id, sect_id, size, level It contains few records for each 'team' entity (referenced with 'team_id' field). Each record represent sector of team's stadium (totally 8 sectors). Now it is necessary to implement few searches: by overall stadium size (SUM(size)); the best quality (SUM(level)/COUNT(*)). I could create query something like this: SELECT TS.team_id, SUM(TS.size) as OverallSize, SUM(TS.Level)/COUNT(TS.Id) AS QualityLevel FROM team_sector GROUP BY team_id ORDER BY OverallSize DESC / ORDER BY QualityLevel DESC But my concern here is that calculation for each team will be done each time on query performed. It is not too big overhead (at least now), but I would like to avoid performance issues later. I see 2 options here. The 1st one is to create 2 additional fields in 'team' table (for example) and store there OverallSize and QualityLevel fields. If information if 'sector' table is changed - update those table too (probably would be good to do that with triggers, as sector table doesn't change too often). The 2nd option is to create a view that will provide required data. The 2nd option seems much easier for me, but I don't have a lot of experience/knowledge of work with views. Q1: What is the best option from your perspective here and why? Probably you could suggest other options? Q2: Can I create view in such way that it will do calculations rarely (at least once per day)? If yes - how? Q3: Is it reasonable to use triggers for such purpose (1st option). P.S. MySql 5.1 is used, overall number of teams is around 1-2 thousand, overall number of records in sector table - overall 6-8 thousand. I understand, those numbers are pretty small, but I would like to implement the best practice here.

  • Mercurial vs Subversion. Whose performance is better?

    - by Chicago
    There are a lot of articles about SVN vs. Hg in general. I would like to concentrate only on performance. Real-live experiences preferred. Here is my set-up: (future setup) Windows with IIS fro Hg (current setup) SVN 1.3.2 on top of apache under windows I would like to have statistics for most commons operations (commits, stats, local/remote pulls, pushes, etc...). I am not really sure what are the most common operations for Hg.

  • What are some Coldfusion (mx7 and greater) "Gotchas" that I should know about?

    - by jakeonrails
    I just spent half the day troubleshooting what is apparently a rather famous gotcha for Coldfusion MX7 and below: The nested query loop bug: Where you are required to reference the current_row of the outer query or else you will only see the first record. For example: <cfloop query="outer"> <cfloop query="innner"> <p>#outer.field#</p><!--- this won't work, you'll only get the first row ---> <p>#outer.field[current_row]#</p><!--- you must do this instead ---> </cfloop> </cfloop> Are there any other ways in which ColdFusion does not work in the obvious way?

  • does such a c++ tool exist? [I dont know what to call it]

    - by VSC
    Hello, I am going through the process of trying to figure out how a library of code works. I would like some sort of tool that would analyze the program that I run off of the library and tells me what functions are called in what order by each thread. Does such a tool exist? What google terms would I use to find such a program? Note: Using VS2008/Win7/C++

  • Nested If (x) checks - Better way to write this?

    - by Will
    There are places where I check for valid pointers before I perform an operation with them; these checks can be nested pretty deeply sometimes. For example, I have if (a) { if (a->b()) { if (a->b()->c()) { a->b()->c()->DoSomething(); } } } I really don't like the look of this. Is there a way to turn this into something more readable? Ideally, if (a && a->b() && a->b()->c() ) { ... } would be great, but obviously would not work.
