Forms Data Controls :: Unable To Filtering GridView
May 2, 2010
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.

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'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?

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 ?

after 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:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
AppendDataBoundItems="True">
<asp:ListItem Value="1" Selected="True">A Type</asp:ListItem>

I 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'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
If

I have a gridview that holds a bunch of companies (600 of them). I have a textbox under the gridview so people could type in a partial name of the company and basically do a search on the gridview. My problem is that when I run the page the only thing that shows is my search textbox, I'm assuming this is because I have setup the SQLDataSource to filter based on this textbox. I'd like the grid to be filled when the user opens the page and only filtered when the user type something in the textbox and hits go. Does anyone have an example of that in VB that I could look at?

I've got a GridView populated via a SqlDataSource whose Select command is controlled by a DropDownList. This is all working nicely:
How do I support the "All" user choice:
In other words, when the user selects "All" there are no aircraft names that match that so nothing is returned. Instead, I'd like the select statement to skip the WHERE clause in this case and just show everything. Do I need to create a second page for this case or is there a way to programmatically alter the SELECT command or some other way to accomplish this?

I have a GridView that displays records from an Access database, and I want to filter the records using a selection from a drop-down list. The GridView populates on page load with all of the records. The drop-down list is populated at page load from a different table in the same database. The functionality of creating a new GridView filtered by the selection in the drop-down list is working. However, when a different page number is selected from the Pager of the GridView, the GridView "disappears," or isn't redrawn. The selected name remains selected in the drop-down list, but there are no GridView elements displayed. If I select another item in the drop-down list, I get a new GridView with the correct records, but then choosing a different page results in no GridView. I'm guessing there's something wrong with my OnPageIndexChanging for the GridView event code, but I'm not sure what. My code is below (C#, ASP.NET 2.0):
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
