Problem with ViewState on Foreign Key Filter

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ASP.Net

I have a site that is no longer working properly in preserving viewstate on a QueryableFilterRepeater, particularly on Foreign Key fields.

To explain, suppose you have a drop down list autogenerated through the QueryableFilterRepeater control on List.aspx of Products, showing a list of products with a drop down list of Parent Categories.  Choose a Category (say "Toys"), and the List filters properly.  Now, when I hit the BACK button on the browser, the List goes back to the original ALL products, but the drop down control no longer returns to "All", but stays at the previously selected "Toys".

I cannot determine WHERE in the code my viewstate (or other setting) is preventing the drop down control to reset itself as the grid does after hitting the BACK button.

Any help appreciated.

POST from html form viewstate problem

<p> Hi all, I have a website where people need to pay for a specific download (.pdf file). After they payed they get the download(A). My payment-provider can do a HTML-Postback to the site i want, for each succesfull payment. So the idea is that if someone payed, they do a postback to my server with a couple of parameters, so i can know that that specific email address has payed, and they get the download. I tested localy with a .html file on my desktop to postback a set of parameters to my local asp.net website. But in ONLY works if i include the __VIEWSTATE in my html file. And i cant get rid of the viewstate in my HTML of the aspx page. >test.html: <html><head></head><body> <h1>Dit is een test</h1> <form id="form1" action="http://localhost:25659/WebForm1.aspx" method="POST"> <input id="Button1" type="submit" value="submit!"/> 'IT ONLY WORKS IF I INCLUDE THE NEXT LINE: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMjA0OTM4MTAwNGRk" /> </form></body></html> Has anybody an idea to acomplish my goal? Maybe i can get some info about the postback in my global.asax? or create a HttpHandler for .html files? Anyone?   Thanks in advance, Vincent   </p>

Apply a Filter in a Select statement Problem


Hello all

I need to select some rows from a table and apply a distinct on two of the columns (keeping the most recent one) and get all the attributes of the selected rows.

for example

if I have a table with the following rows and coloumns

1 1 1 1/1/2010
2 1 1 2/1/2010
3 1 2 1/1/2010

I need to do a select distinct on columns A and B keeping the most recent row and return all the coloumns of the selected rows

so i need the result to be rows 2 and 3 and discard row 1 because there is another row (2) having the same data in columns A and B and the other row (2) is more recent.

I tryed creating a veiw, use a common table expression and create a stored procedure...

but my knowledge with sql is limited and cannot get the result i want...

Is there a way of getting that result without having to change the database structure?

Any suggestions are welcome


Problem with radiobutton list when viewstate disabled



I am having an issue with dropdown list when viewstate is disabled. The selectedindexchanged event fires even for the other events on the page.

I am pasting the code bello. To reproduce the issues I am mentioning please change the selected value of the dropdownlist and then click any button the selected indexchanged event fires even thought we didnot change the value.

<%@ Page Language="C#" AutoEventWireup="true"  EnableViewState="false" %>

<script runat="server">
	protected override void OnInit(EventArgs e) {
			new ListItem("Option 1"),
			new ListItem("Option 2"),
			new ListItem("Option 3"),
	protected override void OnLoad(EventArgs e) {
		SelectedValueOnLoadLabel.Text = OptionsDropDownList.SelectedValue;

	void OptionsDropDownList_SelectedIndexChanged(object sender, EventArgs e) {
		SelectedValueOnSelectedIndexChangedLabel.Text = OptionsDropDownList.SelectedValue;

    protected void btnTest_Click(object sender, EventArgs e)
        SelectedValueOnLoadLabel.Text = OptionsDropDownList.SelectedValue;

    protected void TestButton2_Click(object sender, EventArgs e)
        SelectedValueOnLoadLabel.Text = OptionsDropDownList.SelectedValue;

Problem trying row filtering - Need Filter Template for string columns


I'm still really new at DD.

I need to do straightforward filtering of tables on columns that are simple string/text/varchar type.

I'm trying to follow the direction given in http://blogs.msdn.com/b/morebits/archive/2009/04/14/customize-table-rows-filtering-in-dynamic-data.aspx 

 I have added the DynamicFilter in my markup like this:

<asp:DynamicFilter ID="SellerFilterID" DataField="SellerUserId" runat="server" OnFilterChanged="DynamicFilter_FilterChanged" />

I have added the QueryExtender and Dynamic Filter expression like this:

            <asp:QueryExtender ID="CustomerCustomQueryExtenderID" TargetControlID="GridDataSource" runat="server">
                <asp:DynamicFilterExpression  ControlID="SellerFilterID" />
I get the error that I expected because the blog warned that "It will throw a 

Problem with Filter on Status in CQWP


I have set up a task list (straight OOB) in each sub-site of a site. The Manager wants me to set up a CQWP on the top-level site that will show her all of the tasks on every sub-site that have a Status column value of "Not Started". I have tried filtering to the exact value (Not Started), filtering to "contains, Not", etc. None of these filters will produce the desired result. No success, nothing shows. I can filter on Priority just fine using either exact values or "contains". Is there something about the Status column that causes this to fail in a CQWP?

I tested Views and I can set a View to show all tasks equal to "Not Started. So I am perplexed why I cannot do the same thing in a CQWP.

Problem in displaying values for foreign keys in Dynamic data asp.net web app


I have the following tables in my database which are as given under:


Table 2: CREATE TABLE [dbo].[PromotionCodes]( [PromotionCode] nchar NOT NULL, [CustomerPromotionDiscountID] [int] NOT NULL, [EmployeePromotionDiscountID] [int] NOT NULL, [IsActive] [bit] NOT NULL, CONSTRAINT [PK_PromotionCodes_1] PRIMARY KEY CLUSTERED ( [PromotionCode] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]

There is a foreign key relationship between columns (1) PromotionID of table PromotionDiscountValues and CustomerPromotionDiscountID of table PromotionCodes and (2) PromotionID of table PromotionDiscountValues and EmployeePromotionDiscountID of table PromotionCodes

When i browse the PromotionCodes table in the dynamic data listing, the following columns get displayed:

  1. PromotionCode

  2. IsActive

Dynamic Data Foreign Key Filter - how to limit the # of dropdowns on the list view



I have a visual basic website in VS 2010 framework 4, linx to SQL, with scafolding.... and this dataclass has about 10 foreign key fields, of which all 10 are shown in the list view of the website.  I want the ability to exclude those filters from the list view (or exclude some and keep some), but without eliminating them from the edit forms.  Using <scafoldingcolumn("False")> does the trick to remove them entirely but that will also remove them from the grid/list itself, which I don't want, and remove the column from the edit record views, which I don't want either.

Any help would be great!!!!

Using jQuery to Filter Table Rows

The project is using the .net GridView control, so I had limited control over the output HTML code. Still, I think this code can work for most tables. One thing to notice: you should use the class "filterable" on your table or on one of its parents for the code to work.
First, we need a text box:

ASP.Net Caching problem ??


I'm having a problem with an asp.net 3.0 application using a gridview to display data.  The problem seems to be that despite a brand new .selectCommand being sent to the sqlDataSource, the gridview starts displaying data from *someone else's* query.  For example, user A is logged in and will be working fine until a few page submissions later when the gridview data starts suddenly showing information that belongs to another user. 

This is my first asp.net application, though I've been working with classic asp and ADO for years so I'm used to sending a SQL string and getting back the results from that string.  Apparently there is a complex caching system which is interferring which I do not at all understand so at this point I just want to stop the server from caching any data whatsoever.  Is this possible?

Any and all help will be much appreciated!!
