SQL Server :: Multi Select ListBox - Retrieve Records Where The Column IN NULL?
Aug 4, 2010
Using a ListBox, where multiple items can be selected. Using StringSplit SQL function the string passed from Listbox is separated where the delimeter is comma ( , ).ListBox is in search form where user enters search criteria using other controls and the ListBox. All works good by simply using below SQL statement in Stored procedure that carries search.
[Code]....
Question:- Now one of List Item is None , when None is selected or None is selected with other ListItems from ListBox it is required to retrieve all records where COLUMN IS NULL.Example: When the Male, Female and None is selected from ListBox, SQL statement in Stored procedure will be
[Code]....
Like to know how this can be handled? It is required to retrive NULL values when None is selected in ListBox as well as in combination of other ListItems(Male and Female) i.e., Male, Female, Null when user selects multiple items from ListBox.
I am trying to create a multi column listbox by combining fields in Linq select statement, as Let Name = Last + First. The problem is how to pad the Last column with spaces as you would in SQL using REPLICATE so when I bind the listbox to the data, it looks like two columns.
Does there exists a listbox control in ASP.NET which allows multiple columns and multiple selection? I looked but couldn't find, so what options do I have available now?
I'm creating a search form that will include textbox and multi-select listboxes. I figured out how to load the listboxes but not how to grab those values on the postback in the controller method. Here's my simplified code:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.ComponentModel.DataAnnotations; [code]...
I couldn't come up with a good subject. I have a simple ASP.NET 3.5 form. If you follow the numbered comments, I explain how I am stepping through the code when I run the page in debug mode. Both of the below functions are methods declared in the code behind file of the page, both are in the same _Default class. The ManagersListBox is declared in the Default.aspx page. Why is it that in the context of the GetSubordinates, the ManagersListBox is null? It's as if it disappears for a moment and then reappears after returning from the GetSubordinates method. Obviously the solution is to parameterize GetSuborindates, but that is not my concern. I am trying to learn how ASP.NET works and I would really like to understand why I am seeing this behavior "disappearing object".
Formview with some Accordion block. In the block there are some complex structure, displayed with GridView. (but the GriewView is generated dynamically by input ) For the GridView has some rows, I converted it into a string and stored it in a "Column" (or said "field") of a record.
But when i doing search. I cannot bind the gridview to the "column". because string has to be converted manually into dataset to be accepted by gridview.
I just hope to do the coverting in the "Selected" event and databind the gridview with the data converted.
Retrieve An colom in a database its name is ItemPrice (witch i know how todo) then when i check 3 Checkboxes and click an button it multiplys the value item in the Itemprice colom you can look at my prodject and understand what i mean an this link (NOTE: you must first select the dates then click search availabilty)then you will see the checkboxes via System.Web.UI.Controls
I have a table converted from Access and the identity keys were lost. Now I need to make the id column the identity column, but it already has a lot of null values, how do I auto generate integer values for the null rows? The row ids are incremented, so if there is a way to auto increment the ids
I'm looking to build a user control where the user should be able to select N number of files for upload using the same "file/explorer" dialog/control. Currently, the FileUpload control enables a user to select only one file for upload. I have seen examples where people have modified this, so that uploaded files are stored in a list to provide a "mass upload" functionality. However, the user can select only one file at a time. This is NOT what I want, the user should be able to select multiple files at a time, or select a folder with which I should be able to upload all the children images. Is there any way I can do this or has someone done this already and i'm somehow missing it?
how can we retrive records from sql-server between two dates. Dates are specied using DateTime datatype of C#. Also the stored date in sql is of Datetime type.
I am using ASPNET2008 with VB Scripting and not C# Scripting I am encountering new problem.
On the WebFrm1, I just don't know how to write the coding to retrieve the CUSTOMERID data in order to retrieve the details from SQL SERVER table to fill the textbox controls.Here is the decription of the GRIDVIEW column
In the GRIDVIEW1 on the left edge one of the column is SELECT button which let the userclick on it to select the specific CUSTOMERID on the column next to it on the right.
I have a requirement that user can enter data into a table only once in two date and time ranges in a day as:
from 6 AM to 5:59 PM and from 6 PM to next day till 5:59 AM.
for Example:if today 25/ Nov/2010 at 9:45 AM i have entered a record then if i again try then can not enter the record in table till 5:59 PM but i can enter again today after 6:00 PM till 26/Nov/2010 - 5:59AM.
I have an SQL 2005 db with a table named "industry_suppliers."
I've created a query to enable someone to search this table using 3 parameters.
The results need to be grouped by "product_description" (which is essentially a category). When displayed on an .aspx page, for example, the results need to look like this:
Apples
Acme Apple Company Bradbury Orchards Oranges A1 Citrus Company Belfast Growers, Inc Bradbury Orchards
Notice how "Bradbury Orchards" is repeated under both categories. This is the result I want, EXCEPT in cases where someone wants to filter the search results by category. Let's say someone wants to search just for apple suppliers. The problem I'm having is that any record that appears under apples will also get listed again under any other categories associated with that record. So, searching for apple suppliers, the results are this:
Apples Acme Apple Company Bradbury Orchards Oranges Bradbury Orchards
I'm having trouble figuring out how to revise my query to avoid this problem.
I have two sections of users data on my site, customers and employees, each one has a UserID that is FK to the UserID from aspnet_Users table.
I have a table that stores User messages
Looks Like This:
[URL]
It Has a FromUserID and ToUserID
Because Employees are Identified through EmployeeID and Customers are identified through CustomerID, I needed to use UserID's so Employees can leave messages for employees and Customers and Customers can leave messages to employees and other Customers 1-2 and 2-1
My Quandry is this, How Do I retrieve the information if the UserID might be a Customer or Might be an Employee, when the UserID could be from one of two tables
ie
How Would I Write?
SELECT wms.FromUserID, ed.FirstName, ed.LastName FROM ed INNER JOIN wms ON wms.FromUserID = ed.UserID OR SELECT wms.FromUserID, cd.FirstName, cd.LastName FROM cd INNER JOIN wms ON wms.FromUserID = cd.UserID
Id - Date - Type 1 - 2011-03-01 - 1 2 - 2011-03-02 - 0 3 - 2011-03-03 - 0 4 - 2011-03-04 - (-1) 5 - 2011-03-04 - 0
Can I somehow select the records between a record having type 1 and type -1 without using a cursor,for example the records with ids 1-4 in this example?
I have stored procedure which selects records from an SQL table based on a bunch of user-input parameters.Just discovered that if a record in the table has null values in some of the columns (I haven't figured out which ones yet), then the SELECT is not returning the record (even if it satisfies all the parameters).The SELECT statement is supposed to allow for nulls, and I've been over it a bunch of times and am not sure what I'm doing wrong.Or do I need to get rid of all the null values in the SQL table, and prevent new ones from being introduced?
i have a query that select random records in access database in terms of time : "SELECT TOP 10 * FROM Tbl ORDER BY Rnd(-10000000*TimeValue(Now())*[ID])" now i wish to convert this query for using in sql server 2005 such that return random records in term of time
I thought I had this down. Why isn't my code handling this? It starts writing rows and it gets to the NULL row and then it chokes because the value in the cell is null. I said in the code when it sees the null to assign "". See last line.
Actually i'm doing a project on quiz..i created a questions table with fields qno,qdesc,a,b,c,d,answer....then i wrote a store proc to retrieve qno,qdesc,a,b,c,d randomly.SELECT top 5 Q_No,Q_Desc,A_Opt,B_Opt,C_Opt,D_Opt,answers from [dbo].Questions randomrows ORDER BY NEWID() and another store proc to retrieve answers randomly. SELECT top 5 answerst from [dbo].[Questions] randomrows ORDER BY NEWID()
but finally i'm getting 1st store proc n 2nd store proc randomly...But the answers related to that particular qstn r not matching. how can we retrieve a column present in one stored procedure into another stored procedure
Any one know any open source user control that is similar to gridtreeview. Basically, I want to show a multi column treeview that when expanded, user can edit certain column values. The columns can have a text box or dropdown etc.
