DataSource Controls :: An Application That Populates A Gridview Based On Criteria In A Table?
Apr 16, 2010
I have an application that populates a gridview based on criteria in a table. I have another table that holds data to be omitted. I will post the current LINQ code and also the end result SQL code that I need to figure out in LINQ. Below is my code:
Current LINQ Code:
Dim TestType = (From test In db.Table _ Where test.TypeId = TypeID _ Select test.Id, test.Title)
I want to select data from a table where the user can search by 3 options; date, keyword, and type. The date will always be either today or a user chosen date. The keyword can be null or something the user inputs. The type will be chosen from a drop down and can be all or a specific category. I know how to search the date, but the other two create complications. I have created a stored procedure trying to figure this out:
[Code]....
Is there a way to say if the keyword is null then don't use it as a search criteria. If that is possible then type can use that same logic I suppose.
I want to know how to create a textbox in VS2005 where in the box I would type the name of my favourite sports team and once I've pressed the submit button a Gridview table would populate displaying the the name of the team and a image of the club/team shirt.
I'm trying to update one my my tables from a field in another table.
I have Address fields on both tables and the old table has some addresses I need to copy over (I dont want to copy/paste or type them all in obviously). I basically need to:
I have a dropdownbox which I want to use to search records based on a timescale. The gridview populates results based from that search.
So here is how I want to work this;
If a user selects "today" - a list of records input today are populated. If "this week" is selected, a list of all records added within that week from todays date is populated.
I created a forum on this issue previously but to no avail whatsoever. How do I work around this problem?
ItemNo refno Process Name Qty 001 1 A John 50 001 2 A Jon 150 002 3 B Kalis 100 003 4 A Bob 300 Second Table ItemNo Newrefno Process Name Qty 001 001 ZZ peter 50 001 001/a ZkZ Joe 70 002 002 Ab Ray 100 Result Set 001 A John 200 001/a ZZ ZkZ peter joe 50 70 002 B Kalis 100 002 Ab Null Ray Null 100 Null 003 A Bob 300 null null null null null null null
Here first row of the result set explanation:
up to this 001 A John 200 based on first table sum...
and 001/a zz ZkZ peter joe 50 70
here 001/a newrefno of 001 so i need to show all the ItemNo 001 record in one row like the above resultset.
I am having a staff table which contain staff information on it. To search staff information from the table, I want to prefer filter style. For example in the select query I want to display staff information according to three criterias. Select staff information from all sections, Select staff information from a given section, select staff information by a given Name. All these selects must be performed in a single select statement. Suppose,
SELECT * FROM StaffDetailsTbl WHERE SectionID = CASE WHEN @SectionFilter IS NULL THEN [SELECT ALL] ELSE SectionID = @SectionFilter and Name = CASE WHEN @NameFilter IS NULL THEN [SELECT ALL] ELSE Name Like '%@NameFilter%'
Where Declared variables are parameterized stored procedure values retrieved from the user.
I am upgrading and re designing my current ASP.NET 2.0 website to ASP.NET 3.5 to take advantage of the 3.5 feature set.As part of the re design I am going to use Linq to SQL classes.
The web based application I am working on is an N-Tier application. In the past I have always used an ObjectDataSource when binding against UI controls.I just read an article about the LinqDataSource.After reading this article I am toying with the idea of using the LinqDataSource for selecting data into controls where I only want to select and not change the data (i.e. drop down list boxes or gridviews that don't perform inserts,updates or deletes).Before I go down this path,I was wondering if this is a bad idea and that I should just stick with the ObjectDataSource?
I have a insert into statement thats inserting my numbers from a numeric text box on my aspx page. I am choosing the Amount Type then putting in a a number.
So i have a drop down that i select example Direct Charge then i enter 600.00 and click add it puts that in to the databse for me woot..
I then put in say Misc Credit and enter 200.00 it inserts in that into the database woot.
The look up table that has my amount types has a field called numeric opperator which is either + or - the Credit being a - and the Charge being a + then my stored procedure takes all my + numbers and adds them up and subtracts all the - numbers.
I want to change that so that it actuall be inserted into the table as a - number form the start. So I want choose Misc Credit enter 200.00 and click add then my event says o yea thats a credit insert 200.00 as -200.00
I have a form that searches for images in a database. I have several DropDownLists with various search criteria e.g. Genus, Photographer, State, Project.I'd like the user to be able to filter using any combination of these. For example they might pick a specific photographer and a specific genus but choose not filter by project or state.I'd like to find a good, clean, elegent way to do this.Here is an example of the code I have now, it has only two possible criteria. It works but I have a feeling there are better ways to do this....
I have a gridview with two textboxes (first name & last name) and a linkbutton to search results inside the gridview.
I have made select parameters as well and the search works if i write in both textboxes. However, if I leave one textbox blank, i don't get any results.
[code]...
How can I get results from searching only one textbox?
How can I display my table (one sql table)say i have 10 list of products in "houseware" category and the other 10 list is "food" category..
so i have 20 list in my table but only want to show only one category at one time using dropdownlist to activate one category at a time. also i want to display them using multiview component available in asp.net toolbox.. i'm using c# language..
I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?
I have been working with this database for some time. Here is the situation...
I inherited a MS SQL database that has hundreds of tables with similar data. For instance:
FordTampa_customer is a table,
ChevyAtlanta_customer is a table, etc....
All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...
So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.
All right, on to the real point of my post...
Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.
I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:
[Code]....
I am not sure how to take those names from the table and do another select based on that list of names.
I have a web form with two drop downs.I want the gridView to display the data based on one or the other.The user can then select a record to be displayed in a detail view.This method works as long as I am only viewing the data.If the user edits the data in the detail View and then updates the detail view when the page reloads the grid goes blank.I have traced the code and there is data in the query after the update but the select statement for the LinqDataSource is overriding the code in the lqGrid_Selecting.I can make the above scenario work using SqlDataSources,but I thought LinqDataSources were the way of the future.
I have an updatepanel. Inside that i have some controls for selecting search criteria. For search button onclientclick iam calling javascript functon for validation and in onclick iam calling the mathod to populate the gridview. On clicking search first time it is not loading the grid and clicking the second time it populates.
I am creating a form that has several fields at the top such as date range, area, etc, the user can change and click a submit button to view all the rows that match in a gridview below these fields. I need to know how to change the "Where" condition based on the user input on the datasource bound to the gridview.
I have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.
I had just started with Visual Studio 2008 + VB.net. I've now designed my tables, and basic gridview functions properly.Now I'm faced with the problem of having to calculate a value based on 2 - 3 columns/data in the gridview, display the result in an existing column in the same gridview, and saving the calculated value in the datasource.I had initially created the "Total" column as a textbox displaying a manually calculated amount that is saved in the datasource. Now, I want to change the field to auto-calculate based on 2 other columns.
