ADO.NET :: Dynamic Or Condition From Joining Multiple Table?
Feb 14, 2011
I have to seach data from multiple table and fetch the data and from the result i have to search partical value in or condition .
Means i have 5 table from which i am fetching data and after that ihave to search multiple location means array location and from that array i have to check each location into fetch data.
I have been trying to make this work for a while, but I have not been yet able to figure this put. I am using VS 2008 and mysql database. I wrote a query and checked to see if it works in database. It does.
I have a gridview, whose select command is that query. But for some reason, I just get all the rows from one table only. I rechecked my datasource and it is ok. I read on some discussions that it is NOT possible to have data from two tables in a gridview. Is that true? If that is not true, how can I have data from multiple tables in a gridview? Or any other web control for that matter.
I have a dynamic Table which contain 8 rows and 8 Colums
Table t = new Table(); TableRow rr = new TableRow(); TableCell cc = new TableCell(); and in the each Cell CC I add a dynamic Button(Or Linkbtn) LinkButton LB1 = new LinkButton(); LB1.Text = "AM"; LB1.ID ="Link1"; cc.Controls.Add(LB1); rr.Cells.Add(cc); LB1.Click += new EventHandler(LB1_Click); t.Rows.Add(rr);
i have a table with 8 rows , 8 colums and each cell contain a LinkButton (which diffrent in IDs) I want to add Lable in the same cell of this LinkBtn(LB1) which it clicked but I cann't What shoud I write here?
I have created one stored procedure which runs on 5000 users in tbluser table with some filter condition in database.There are 4 filtering condition(FC1,FC2,FC3,FC4).Filtering condition has some ListBox and dropdown list of department and countries.I want output as given below:
ID Name StaffNo department Points 1 KK 111 dep1 2 2 NN 222 dep2 1 3 DD 333 dep3 4
I got ID,Name,StaffNo,department in resultset but not points.
points calculation would be based on filtering condition like
if FC1 matched user gained point 1,if both FC1 and FC2 matched user gained 2 point,if both FC1 ,FC2 and FC3 matched user gained 3 point etc.
--in stored procedure i m using dynamic query DECLARE @SQL VARCHAR(2000) SET @SQL = 'SELECT U.UserID, U.StaffNo,U.FirstName+'' ''+ U.LastName AS EmployeeName,''?'' AS Points FROM tblUser U '[code]....
all filtering condition are implemented with OR logic.
The gist of the problem is that we have an alumni table (one record per person) and also a couple of other tables (one to many) that have degree info and interest info. In a search screen in our app you can search for criteria that spans all three tables (there are actually more fields and tables than shown in the example below but I am trying to keep it simple).
The code below works (properly returns people without degrees for example) but still feels a little clunky or over-engineered to me. Are there easier ways to do this? NOTE: I have been through quite a few iterations/approaches to making the correct data be returned.
I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3) A CheckBox (Item4) A CheckBox (Item5) A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:
I am trying to generate a dynamic table andd add rows to a ASP.Net table control on my UI. My problem is as I add a new row from MyTable, in to another table the table I am copying from, will loose one row. Here is the code:
Table myTable = new Table ();
[Code]....
am just reading one row in every loop and add that row in to another table object, why is 'myTable' loosing loosing one row in each loop?
I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet.
string strCondition = "FirstName=='abc'" from p in People.Where(strCondition) select p
In our architecture we are usign both Linq-Sql as well Linq-Entity. So please give some thoughts wehter it is possible or not and is there any way to perform this?
I've scenerio where i've two dropdownlist box (one dependent on other, displays handset brand name and on selection displays the respective model name), two combolistbox which is bounded to their respective datasource(Displays the fault and accessories).
Now i've to update the three tables booking(Handsetid, Brand,model), accessories(handsetId,AcesoriesID) and fault(handsetID,faultID). Ive to update multiple rows in Accessories and fault.
These controls are present in datagridview EditTemplate
I´m looking for some advice on how to create an table showing bookings, a table containing mon-sun on the horizontal axis and times at the vertical. The admin is able to edit each days bookable times (first bookable time, last bookable time) - The slottime is constant.
What I want is let the admin click on eacha cell to remove it/add it when removed. And other features as well, like create an booking for a customer.
What would be the easiest way to achive this, at the moment I use dynamic links since I cant get asp:buttons to work and the code to create an dynamic asp:table row by row and this produces some ugly code.
So any advice on how to achive such an "schedule".
I'm not sure on the best way to go about this one. Simply LINQ queries are easy enough for me, but I am looking for the most efficient way here.
I have 2 tables, Sliders and SliderItems. SliderItems have a FK that points to the Sliders Id.
I have been getting information on a particular slider like this:
public static List<Slider> GetSlider(Slider sItem) { DBContext db = new DBContext(); if (sItem.Id != Guid.Empty) { var list = from tbl in db.Sliders where tbl.Id == sItem.Id orderby tbl.Id select tbl; return list.ToList(); } }
So what I need to do for my home page is pull back a set of data that I want to stuff into a data list. Thereby combining the Slider + SliderItems that go along with it.
Do I just do a normal LINQ query with a JOIN statement and toss them into a generic list that goes back to my DataList?
I have prepared a web project using ASP.net MVC. I want to display data by joining 2 or more tables and on Edit performing updation in 2 or more tables.
I have 2 tables : Employee_master(EmpID,Name,Designation) Employee_Detail(EmpId,Address,Phone,DOB).
I am using ADO.Entity framework to create the model.I want to perform following operations.
1.Applying 1:1 association between the tables. 2.To show the information EmpID,Name,Designation,Address,Phone for all the existing records in tables on View. 3.On Selecting the Edit link want to show EmpID,Name,Designation,Address,Phone for the corresponding EmpId in EditView and then perform updation of the records in 2 tables both in Employee_master,Employee_Detail on Save.
I am trying to have the collection of order IDs be used in my where statement how come i can't get this to work?
List<int> orders = new List<int>(){1,2,3,4,5}; DataTable dtTable1 = getOrders(); DataTable dtTable2 = getOrderDetails(); var results = from a in dtTable1.AsEnumerable() join b in dtTable2.AsEnumerable() on a.Field<int>("ID") equals b.Field<int>("ID") where orders.Contains(b.Field<int>("OrderID")) select a;
