I have been searching the net for quite a while and can't find an example of how to put a radiobutton or radiolist inside a formview. I have an objectdatasource that goes back to a table. One field in the table is Hydro -- which is an int field. There are three valid choices:
value Text
0 None
1 15 Amp Service
2 30 Amp Service
When I set my Formview to the objectdatasource my Hyrdo binding looks like this:
[Code]....
How would I change the above so that it would replace the TextBox with either a radiolist or 3 radiobuttons (I am ok with whichever is easier) so that it would look like this
Hydro: o None o 15 Amp o 30 Amp
Also, in the case of the update mode that the correct item is selected based on the value of 0, 1, 2 being read from the datatable
I'm new for asp.net and web development at all.

Are there common technics for this?
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?

View 6 RepliesI 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?
I just want to position the first label in a position on the left and then the start position of the second label at a position. I can't use relative because of the different lengths of the strings. But I the absolute will not work. I tried putting position relative in the cssclass phoneCostsStyle but it doesn't work.

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.
on which all conditions we use dataset and datatable to bind data to a gridview?

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 dataset with sum(column1),sum(column2) , how can i take data in column1 into textbox1 or label1, column2 to textbox2.

View 1 RepliesI 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).
