Asp.net - Gridview Filtering Via Joined Tables?
Oct 15, 2010
I'm trying to display data which comes from a join on two tables (or more) in a gridview I want to be able to filter the result set via user given input (text boxes on page)I have tried the standard tutorials but cannot find something which goes beyond displaying one table result sets in the gridview. If I go through the configure gridview and configure datasource wizard for any datasource (sqlDatasource, object, entitydatasource), when I use multiple tables I cannot use the 'where' parameters in the wizard, and therefore need to have the selecting code in the code-behind, but i'm unsure where exactly to put this.

I know this has to be easy. I'm just not sure of the best method to use. Should I be using ViewData?
Table 1 has columns:
ID
Name
TypeID
Table 2 has columns:
TypeID
TypeDescription
The tables are linked by a key on the TypeID column. I want to display:
Table1.ID
Table1.Name
Table2.TypeDescription

Im having a go at doing a report for my asp.net application. I have 2 tables, one which lists a loan we have given to a customer, and another table which lists repayments against the loans.
I want to display each loan and how much is outstanding against it. My problem is that each loan is repeated in the table for each repayment against it. So when i try to sum up the loans awarded to a customer, if they only have one loan and have made 3 repayments against it, it sums up the amount awarded against each record.
eg, if i award a customer a loan of £200, and they make 3 repayments of £50, 3 records appear in the table. The amount awarded is repeated against each repayment, and when i total a customers loan amounts, it totals 3 x £200.
I have put the details into the grouping row, where it is grouped by loan_id, displaying the toal of repayments instead of each repayment. This stops it repeating in the table, but when i total the amount awarded field it still calculates 3 x £200.
I tried calculating the total on the report item after grouping but you cannot calculate on a report item.
Is there a way to stop the table from repeating the amount awarded against each repayment? Or even a way in the SQL statement of the dataset to make it display a total of repayments rather than each repayment. Cant see how to calculate a total repaid as i would need to pass a Loan_id in as a parameter.

I am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...
I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)
Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.
I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.
The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.
I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.
All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.

I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.

I have a dynamic sql query which contains more than one table joined. Normally I get this query to a datatable and use it. For now I want to get result of this query to a list object.

I need to use a grid that allows for filtering in the column headers. I know there are some third-party components out there that cost money. I am looking for something that is free / open-source that can be used on a project. Is anyone aware of a GridView that can do this?

I am new to web page development so I want to ensure I am going down the right path with this new project. Currently, I am populating a mainGridView on my webpage with infomation from my MS SQL database. Two features I would like to add to this page is to be able to add filtering and hot linking/cell clicking events.
I was also planning on keeping the mainGridView dynamic, so that as a user clicks on a cell I could update the mainGridView with new information. Say all of Sammy Davis' movies. I am trying to do all of this inside of code and leave the aspx alone for the most part.
My plan was to embed textboxes into a secondary GridView to handle the filtering. The user could click on a button to filter the query set and the mainGridView would update based on the filter. Since the mainGridView is dynamic I need to have the filters to be dynamic as well.

I'm joining 2 tables and using the formview. When I insert a record, I need to place the value of the max id + 1 of the second table in a field in the first table so that the tables are linked. I'm not sure where to put the value. I try to put it in the insert command and I've tried the select command but that doesn't work.
Table 1 - Product: ID, ProductNum, Brand, Description
Table2 - Brand: ID, BrandName
(Brand from Table1 is linked to ID from Table 2)
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
DeleteCommand="DELETE FROM [Product] ..."
InsertCommand="INSERT INTO [Product] ([productNum], [Brand] VALUES (@productNum, @Brand)"
SelectCommand="SELECT Product.ID, Product.Brand, Product.Description, Brand.ID, Brand.BrandName From Product INNER JOIN Brand ON Product.Brand= Brand.ID"
UpdateCommand="UPDATE [Product] SET [productNum] = @productNum, [Brand] = @Brand ......"
I've Tried InsertCommand="INSERT INTO [Product] ([productNum], [Brand] VALUES (@productNum, MAX(@Brand.ID) +1)"
or setting BrandID =Max(@Brand)

Client-side filtering. Begin typing an Item name in the filter box above the "Item" column (Grid View) a live filtering will take a place to filter the input letter till the user find what he/she is lookin for.

I have a gridview which is attached to an access database and I have created a query that joins two tables together. All this works as expected. However, I have three problems that I need to solve:
I want to filter the results displayed on the gridview by way of a dropdown list. This drop down list will take its values from one of the tables. So, my question is how do I take a value from my drop down list and link it to my query on the gridview? I want to add an value to my drop down list, which is a default value, like "All". How do I add this value to the list, when it is not part of the table that the values comes from and when selected by the user shows all results? When the user selects a value from the gridview and nothing is returned, how do I get the gridview to show a null result message, like "Sorry, your selection did not bring back any results"?

I have a gridview that takes in values from a sortedlist. I want to filter those values before putting them in the gridview without taking values out of the list.
Is there an easy way to do this? Or do I have to redirect the data through another list and point the gridview to it?

I am trying to populate a gridview that returns only the logged in users' records. Specifically, I am getting a blank page when I load the page. To clarify, I get the blank page after successfully logging in to the ASP.Net Membership and do have data to return from the requested table.
I am reaching out to the online community after numerous failed attempts to research the solution and successfully return the desired results through trial and error variations.

I'm using a GridView with an ObejctDataSource. The data is provided by a business object and not a DB. It returns a list of people and each person belongs to a group. Now I need to filter data. For example, I need to return list of people in specific groups. How can I specify a list of groups to be able to filter the data ? Could I use SQL like syntax ? I understand the filter expression works only when data is returned as a datatable. But in my business object I maintain data as hashtables and return as List<PeopleInfo>. Do I need to return list as datatable instead ?
