Forms Data Controls :: Using And Or In Dataset Configuration?
Dec 1, 2010
I am using visual web developer express 2010 and have two dropdownlists which are feeding parameters to my detailsview. both are set to appenddatabound "true" because I have added a % value texted " select all" to them. Now, before I added the 'select all' options I was able to configure my detailsview dataset query to bring over data using the AND statement which meant that the two buttons when placed on the same page brought over values to my detailsview where both criteria were present but when I try this when the wildcards are used with the select all option in the dropdownlists the same does not apply.

I have a detailsview, template as follows:
[Code]....
Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.
I add 2 button to above template to able to edit data at asp page, and added event handlers:buttons:
[Code]....
My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.

I am retrieving data from a web serivce and storing the data into a dataset.
I'm then populating a gridview with the data from the dataset.
Before each row of data is displayed on the website, I need to check and make sure the user has proper permissions to view that data.
Can this be done with a gridview(or any other .NET data control)?
Or would I need to loop through the data manually, and then write each row out manually?

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

I am having dataset and I want to validate particular column for Integer(Numeric) value.
e.g.
ErrorRows = dt.Select("LEN(Year) <> 4 ")
Above I have to validate Year column for Numeric value otherwise it should give me erroneous records which have data other than numeric.

catch (OracleException oe) {

finally { cmd.Dispose(); } } } }
The dataset is being populated, however when the page renders, the data nor the gridview are visible. I have tried using both IE and Firefox, binding / not binding the columns, AutoGenerateColumns Y / N with no success. As I am new to all of this ( VS2008, ASP.NET, C# ) I can't help but to think I am overlooking something basic.
I am using the following :
- VS 2008
- MS Vista SP2
- Oracle XE ( local )

I was searching for my problem for last couple of days. But coudn't find a better solution. So here I go again. What I did which worked great: I was going to a asp page with pre populated Dataset (dataset is already loaded with data), for a GridView. If I do the following .... the GridView shows all the data (with the fields Dataset comes with).
[Code]....
Now what I am trying to do: I am trying to do exact same thing but instead of using GridView, I would like to display data in a FormView. So now I tried to do this
[Code]....
PROBLEM: I can see the FormView Header with text "Test Dataset With FormView" and below the Header it displays the page numbers. I know that I have 3 data in the data set and I can see 3 page link in the FormView. But PROBLEM is it doesn't display any Field / Data. Not sure why it is doing this
Note that I wouldn't know what field to display in the FormView. Whatever I have in the Dataset I need to display. Is there any work around to accomlish my work (maybe by not using a FormView, but other conrol ?). My original goal is to Display Data in a Form View Format (One data at a time

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.

I have a members section of a website where when they first register to become a member, they pick their top 5 sports personalities/stars. Then when they log in to the members area, I want to display members news which should show:
- at the top all new stories that have been their sportstar has been referenced to
- then all other news
(In the CMS, admins can edit a news story and they have 5 dropdowns of all the sportstars so they can for example have for a news story: Sportstar1=Tiger Woods, Sportstar2=David Beckham etc) So as a member, if I have selected David Beckham as one of my top 5s, then all news tagged with him via the CMS are displayed.
There may be a better way to approach it, but basically I am creating one DataSet, then firing off 5 SQL queries, each SQL query is like this:
[Code]....
Then in my Page Load I do this:
[Code]....
The problem is that my repeater is inl showing news for myStar1 i.e. it is nly showing the first table which will be called "News1".
So is there any easier way of doing this? Am I overcomplicating things?

I have an application that needs to read data from a view and do some extensive manipulation prior to delivering it to a chart control (without modifying the original data in the database). I have the chart control on the page, and in the code-behind I've built a dataset which I load and manipulate programmatically to have the table, columns and rows needed (no datareader involved) I'm having considerable trouble binding the chart to the 'in memory only' dataset. Chart Control;
