DataSource Controls :: How To Filter Gridview On Daterange
Oct 20, 2010
I have a gridview, fed from a datasource. Now I need to filter the data based on the values from two textboxes, getting their values from ajax CalendarExtenders.
The original (and working) datasource lookkis like this, just filtering on productnumbers:
[Code]....
Now trying to filter on the dates as well:
[Code]....
Now it goes like this:
I get all records. The productfiltering from the first eaxmple does not do anything anymore (probably related to the next problem)
Entering a date in the textbox (via the calendarextender) and pressing a button to refresh (databind my gridview) throws the following exception:
System.Data.SyntaxErrorException: The expression contains an invalid string constant: '10/01/2010 00:00:00.
Its obviously a type problem, but how do I solve it? Actually i need a daterange (from two textboxes) but simplified it here)
I want to use Drop Down List to Filter Members table by MemberType, this means having to Join the following three Tables..
Members (ID, Title, Forename, Surname, Memb_ProdID*) has Foreign Key for MemberProducts Table
MemberType (ID, MembType)
MemberProducts (ID, Duration, Price, Terms, memb_TypeID*) has Foreign Key for memberType table MembType is in Italic and underlined, how do I use this to filter members details in GridView.
I've got a gridview which works fine. I use dropdownlists which are filled with distinct values of the columns. So when I select an item in a drompdownlist the gridview refreshes based on the selected value. When I have a column which uses string values, I can start the filter with a default % value to use in my select paramaters. But when I have a date column, I can't use that. I use a datasource for the gridview and I prefer to leave codebehind out if this is not needed. Now I use >= in my gridview select to show all rows. but I want to use only = to make the filter work correct when I select a date in the ddl and use the selectedvalue in the gridview selectCommand
<asp:DropDownList ID="ddlUpdateDatum" DataSourceID="dsPopulateUpdateDatum" AutoPostBack="true" DataValueField="UPDATEDATE" runat="server" CssClass="selectinput" AppendDataBoundItems="true"> <asp:ListItem Text="All" Value="01/01/1900"></asp:ListItem> </asp:DropDownList> <asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server" ConnectionString="<%$ ConnectionStrings:GAMSYSTEMSqlServer %>" SelectCommand="SELECT DISTINCT(UPDATEDATE) FROM [messages] ORDER BY UPDATEDATE ASC "> </asp:SqlDataSource> And I use this in the gridview datasource: <asp:SqlDataSource runat="server" ID="dsGridview" ConnectionString="<%$ ConnectionStrings:DBSqlServer %>" SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC" > <SelectParameters> <asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" /> </SelectParameters>
[URL] .... I Need to search record from GridView by using the textbox but not want to configure this with SQLDataSource Manually (Front End) therefore how to filter gridview from Codebehind.
I have seen this question asked about a half a million times and I still haven't been able to get my solution working by reading there answers.
First off I am using visual web developer 2008 express. I am brand new to asp.net net so me="nub"
I watched some videos on how to setup a website soloution and I did got a free cs and all that got it working. I installed the Ms Membership for loging in and out of my website. I got all that working. I installed the database for the membership on a sql server followed the video for doing that and everything works.
I then decided to do something so simple. I thought it was so simple.
I created a dropdown list using the control and I wanted it to go out to my database on my sql server and get my account numbers and filter them by using the current membership member that is logged in. I see that I can display my current user like this
<asp:LoginName ID="LoginName1" runat="server" />
I can see my user log in and out of the website and that seems to work fine.
So here is what my current dropdown list looks like I say current because I have tried this a ton of times with different parm options but none work.
I've got a gridview that I need to perform filters on. All works great until I try and add a date range..
Below is the code. Basically I have 5 dropdown lists which all filter as expected giving them the option to use each one or just the ones they need.
The problem is they want to also have the option of filtering by date i.e date range or greater than or less than or equal to etc..
As soon as I add the date parameter it stops the other filters working. I'm guessing because I have a null value in the date field (textbox) if they dont use the option??
Does anyone have a sample on how to filter by dropdown lists and dates keeping in mind they wont use all the filter options?
I have a form that has dropdown box and user can either select Store Associate or Store Manager, when they click on either, I have GetASsociate function that pulls data from sql database. What i am trying to figure out how to do, is that if they say select Store Manager I want to filter what data to pull from that sql table that has all associates in it, so I was trying use an 'expression' statement to stay if Store Manager was selected, only pull me back the store managers from that table. Then same thing for if they selected STore Assoicate, then only bring me back teh store assocites from that table. But the expression statment does not appear to be working.
asxc.vb code behind Private Sub GetDataAssociates()Dim provider As DbDataProvider' Create a collection of parameters. Dim coll As New DbParameterCollection() Dim prmCompany As New DbParameter provider = DbDataProviderFactory.GetProvider(DataAccessLayer.Enumerations.ProviderType.SqlClient, "GetAssociatesByCompany") prmCompany.ParameterName = "@Company" prmCompany.DbType = DbType.Int32 Select Case ddlCompany.SelectedItem.Text.ToStringCase "Stores" prmCompany.Value = 100 Case "Corporate" prmCompany.Value = 300 Case "Executives" prmCompany.Value = 900 Case "Union" prmCompany.Value = 200 Case Else prmCompany.Value = 0 End Select coll.Add(prmCompany.ParameterName, prmCompany) Select Case Me.ddlOrganisationStructure.SelectedValue.Trim Case "StoreManagers" Dim expression As String expression = "Pos_Group >'0900'" dsAssociates.Merge(provider.GetData(coll).Tables(0).Select(expression)) --IS ERRORING OUT ON ME HERE AT THIS LINE dsAssociates.Merge(provider.GetData(coll)) dtAssociates = dsAssociates.Tables(0) Case "StoreAssociates" Dim expression As String expression = "pos_group < '0900' dsAssociates.Merge(provider.GetData(coll).Tables(0).Select(expression)) -IS ERRORING OUT ON ME HERE AT THIS LINE dtAssociates = dsAssociates.Tables(0) End Select
I try to use a DataViewManager to filter data in a dataset, but somehow it does not work. The code below produces the error "A field or property with the name '< any field>' was not found on the selected data source". However, when I replace "GridView1.DataSource = dvm" with "GridView1.DataSource = ds" it works.
I have an SqlDataSource, which is filtered by two RadioButtonLists. The markup is as follows:
[Code]....
In my code-behind I add the filterexpression when the radiobuttonlists are changed
[Code]....
My problem is that while it works fine when changing the RadioButtonListProducts the filtering works nicely, there is a problem with the RadioButtonListStatus, that filters on the Boolean column, 'Godkendt'. It works nicely if its set to 'Alle' (No filtering on that parameter) but when set to anything else, no records are shown. I suppose the problem is in the filterexpression
i have a "Users today" function that i am trying to work on, i have all the tables set up, and a TimeStamp column, i would like to know how i could get all the users that appeared, but for that day only.
So i used the select statement, but then when i tried to add into query, filtering, i tried using the DateTime.Now, but it only got the users specific to that date, hour, and second.
I am planning a project for a pharmacy to enter quality control data to generate reports and graphs with Crystal Reports. There are 20 stores, I need to password protect the entrance page, giving each store their own username and password (just one per store is fine), allowing the store to only access that store's data. Each store will have an associated ID in the MSSQL table.I am using the Membership Provider. I know I need to implement user roles for Managers and Stores levels (Managers can run reports for all stores), I wonder if I can set the default store ID for insert/edit templates after that specific store logs in.Basically, I think I need to filter SQL queries based on the store ID associated with a user ID. I have seen a .NET site that, after logging in, you type in a store id into a textbox, and it gives you access only to that stores data. Something like this would work for my situation.Can anyone explain or show me an example for the best method to accomplish this with C#?
i have an List<String> lstrings which contains a list of strings. If i want to write a linq query on a list<Employees> employees to filter for employees.name in {lstrings} var lquery = (from e in employees where e.Title =="ASP.NET" && e.Name.Contains(lstrings) select e); Im trying to filter the employees using a list of strings which match with the employee.Name
In my asp.net Page I am using gridview. I am binding the gridview on page load and on paging event with one method. suppose as Bindgridview1();.
There is one search button for searching the records of user with different method suppose as Bindgridview2(); .
when I am searching the records with Bindgridview2(); paging doesn't work and directly bind with Bindgridview1(); which is on page load when I clicked next page.
I'm using a sqldatasource to populate a gridview. I've figured out how to use the dynamic sorting, but I'm curious if there is a way to add filtering on each column. So, if a user wants to pick one specific value from grid, then it would re-populate with only rows that have the specific value selected. Excel has this feature in a workbook, but am curious if this is possible on a vb.net web page.
I have a gridview in which I have price column. I want to apply a slider filter in which user can give range in slider and gridview filter based on the range given in slider.
How do I do this? I'm using a login control inside a loginview control. I want to use the username entered as a parameter in the select statement of my gridview so that it will filter the data to display only the rows that contains that username.
am using GridView with SQLDataSourceI want to add filter DropDownList to the footer of the grid,each column of the grid will have a DropDownList in its footer that has all data in that grid (including data in other pages)how to do that?
