Forms Data Controls :: Filtering Rows Based On A Certain Criteria On A Gridview?
Mar 13, 2010How would one go about filtering rows based on a certain criteria on a Gridview?
View 3 RepliesHow would one go about filtering rows based on a certain criteria on a Gridview?
View 3 RepliesI'm trying to filter data based on the selected value from a drop down list and the according values of a local variable within a gridview_rowdatabound event. For example, if "In Arrears" is selected, the gridview should return all rows where the account balance is less than -100. So far, when I select a value from the dropdown list, it has no effect on the gridview. Here's the code I have:
If (DropDownList1.SelectedIndex = 0) Then
e.Row.Visible = True
ElseIf ((DropDownList1.SelectedIndex = 1)
And (AccountBalance <= -100))
Then
e.Row.Visible = False
ElseIf ((DropDownList1.SelectedIndex = 2)
And (AccountBalance > 100)
And (AccountBalance < -100))
Then
e.Row.Visible = False
End

I have a gridview, based on thsi datasource:
[Code]....
Using a dropdownlist, I can filter (by changing datasource) the results based on customer names in a dropdownlist. This datasource, working perfectly, looks like this:
[Code]....
Now, using a textbox and a ajax calendar, I would like to be able to filter on the date as well, but my datasource so far:
[Code]....
doesn't work very good. In some case sit doesnt show anything, in onther situations - with 10 records for a given date, it only shows one.
Question one: How do I make the last datasource work? Its probably - again-again - something with the datetime formats, but for the life of me, I can't see how to do.
Question two: The Ideal solution would be using the first datasource, SqlDataSourceAllLoads, and then be able to filter the results with filterexpressions/parameters, but again, how? The filterparameters would origin from a DropDownListKunder, matching the tblDeliveredInfo.deliveryInfo_FirmaNavn as seen in the second datasource, while the date comes from the textbox txtStartDate (databinding fired by a button).
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?
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 have a gridview object to which I added
<asp:TemplateField >
<ItemTemplate>
<asp:CheckBox ID="chkCopy"
OnCheckedChanged="chkStatus_OnCheckedChanged"
runat="server" />
</ItemTemplate>
</asp:TemplateField>
The page count is set to 10, when the user checks the checkbox(es), I will need to insert those records in a table. How will I know which row was selected? I found an example (untried) that is designed to loop through and insert the necessary records; but it does not address inserting records based on selecting rows via a checkbox. How do I put everything together.

I have a table in my Database called Creditors.
One of the columns is Paid which is type Bool.
On my aspx I have an objectdatasource and gridview. In the DAL is a method called GetCreditors which
returns all the creditors into the Gridview.
In some cases the "paid" column is ticked and in other not.
I want to run a select query that only gets the rows where PAID is not Ticked. insead
of retrieving all.
I have a gridview with id , name ,age, DOJ
if the DOJ will reach the today date that corresponding row can remove from grid automatically but only in grid and not from the database
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.
View 4 RepliesI 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 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.
View 3 Replies 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.
My website has a "charts" menu item that lets you choose from about a dozen pages each with a different chart in them. Each one of these pages uses the same nested master page which has some drop-down lists and text boxes to let the visitor do some filtering of what data shows up in the charts (I do this by building SQL statement parts in the nested master page and triggering an event that the chart page reacts to).
Anyway, One of the DropDownList controls shows the names of everyone in the Company (I use MembershipProvider and RoleProvider). What I want to is have the DropDownList show a different collection depending on the role that the visitor is in; If the visitor is in the "Principal" role, I want them to see everyone. If they are not in that role, I want them to get only their own name.
I expect I'd have to do this in code-behind... But thought I'd check to see if anyone knows if it is possible to have an "IF" statement in the SQL DataSource for this control that can refer to the role that the current logged-in user belongs to
I've been filtering my gridviews with the FilterExpression of the underlying ObjectDataSource etc. I am wondering how I can implement filtering on my GridViews if I just directly databind it to a datatable etc?
View 5 RepliesI want to filter my gridview using two parameters that come from Dropdownlists.

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 ?
View 2 Repliesafter hours of searching and testing (and found no luck), I came here to ask for your help again. I have a gridview and two dropdownlists. The first dropdownlist (DropDownList1) filters the gridview with Type of Customer. Here is the code on the aspx:

I'm having a HUGE problem with filtering!! I have a GridView1 with data from sql database (table called Requests) >> using asp:SqlDataSource Control.
and I have 2 columns (CV/ Transcript) which are Hyperlink columns..
I want to filter the data by:
1- GPA: for example view all data with GPA more than 3.55 and so on...
2- Credits: same as GPA (view all data with number of Credits more than 135 and so on...)
3- Dept. Name: it could be DropDownList and the user choose the department he wants to see results from.
Does anyone know if this asp.net site has some tuturiols that explains in details on how to apply filtering on a gridview? I have searched for it but I couldn't find any tutorials or examples
View 1 RepliesI was looking for a GridView with Custom filtering, all I could find where the filtering is done like
ColumDate=Value user enters
What I need is the user can filter by any condition Eg >, < , =. Like etc the way we do it in queries.
Is this possible? Are any samples already available?
I have a piece of data that has a refererence number and then account name that looks like this in the database:
111111,Member Account~222222,Trial Account
I have the data spitting out just like that in a grid view, but I am wondering if there is some C# I can put in to where it adds a column when there is a comma and another column when there is a ~ in the data?
i would like to know how can i do the following:
i have this gridview that displays a list of employees, with they're names and also the department they work in. ok so lets say i have a combo box and i want to filter by department, or that i have a textbox and i write "Doe" so that brings all the employees with that last name.
i have checkboxlist & gridview, in which i want to make multi selection using checkbox, so when i click on checkbox the data will filter according to selected check box and appear in grid.
