What you have given is not a server side control.
<input id="rdSelect" name= "radSelect" type="radio" value='<%# Eval("ID") %>' /> is a client side html control.
2 things:
1. Convert it into server control using runat="server" to access it on server side.
2. In button select, loop through all the rows of grid, use FindControl to find radiobutton control. See if it is selected, if so use the row and it's values
Again, using a radiobutton in gridview is little tricky and needs extra effort to group them together so that only one can be selected at a time. If you face issue, just look for article/question on it on this website itself (shared before with lots of users)

Thanks for the reply. I tried using literal, but I am getting an error Quote: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
in this line
output.Text = string.Format(@"<input id=""RowIndex{0}"" type=""radio"" name=""radSelect"" value=""{0}"" checked=""checked"" />");

You forgot to mention the string to be replaced in {0}
Something like:
string.Format("Hi {0}", "there!");

Actually im getting error when the below code is executed from unit test project...
where import is an xml file in the below code..
XmlTextReader importReader= new XmlTextReader(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import"));
the above code is present in one of the methods in different project(class library) which is used in test method in the unit test project
where as the above path is present in web project.
and the value of the
System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import")
is null..ie unable to get the complete path of the file i guess bcos the hostingenvironment is not running(web project)
The above code is working fine when running from the webproject ie it returns the exact path.
whereas returning null value when running from test project.
please let me know how to fetch the file path(where file is present in web project) when running from test project.

Either you need to copy the file in bin/root folder of your test project to access OR give an absolute path of the file to access.

I have some objects I should add to ASP.NET application state. Of course, I can add the object as a whole. The class that object belongs to have some properties and all of them will be added with the object to the application state.
But, is there a way to mark some properties of the class to not be included in adding object to the application state? I've thought about writing attribute, but am not sure if it will work.
Thank you for any suggestion.

Hi All,
i would like to do (ASP.NET-AJAX with C# )an autocomplete search textbox(like Google search) that give the user to choose more than one value to research in DataGrid as follows :
1 | 2 | 3
Rome,Paris,New York
when the user insert the first value can have also the possibilities to insert the second value value and so on ... then the datagrid can show all result requested and preferably i should do it in C# .
DO you have any idea how i can do it??
Thanks so much for your attention
Cheers

You can use this control(Multiselect Dropdown for Web Applications[^]) coupled with AJAX calls to make it as an autocomplete list. Based on the text entered, filter the datasource of the checkboxlist and once the values are selected, use the selected values as a folter for your grid.
Try!

Hello All,
I am very confused to choose among many ways to do a task efficiently. Please suggest me the best way to do the following..
All I want is to "search a sql-database and show up the result in a grid". Note that each row would have an image, a link and some text.
My main check points are
1) Ajax-style grid: On pressing next-page, only the grid should be updated not the whole page
2) Client side pagination: Since the search result might be huge, on each time pressing the next-page, I want to get only the specified rows from the server. NOT THE WHOLE SEARCH RESULT- WHICH WOULD SLO DOWN MY INITIAL GRID SHOWING
.....
Solution Options:::
I am new to web-programming. While browsing through I got the following points...But i am not able to put them all together and somehow i am not confident about it..very much confused what to use and what not to... please help!!!
1) asp.net ajax toolkit
2) use a simple way to create a table with many rows in client side using java script, and get the data form server using AJAX writing the all code of myself. But in this case i need to have a way of pagination if myself
3) etc (may be many other solutions exist)
Practically, there may be many pros and cons which I am unaware of. I am looking for something efficient and easy to use. May be less code.
technology: vs2008/2010, Ajax/Jquerry/JS, sql-db... since havent started teh project I am open to any technology which gives the best solution.
thanks in advance

Based on the following parameters, my suggestions would be:
1. Use a DataGrid and not a simple table to avoid extra code
2. Implement server side pagination such that each page is fetched on-demand
3. Use client side techniques to update the grid - jQuery AJAX, ASP.NET AJAX, Callback, WebMethods, etc.
One mistake in your question: "Client-side pagination" => that means whole data in one go and on page change no data fetched from server. That would not be needed.

From the microsoft site, I can see you can use the log property of the datacontext object for debugging linq to sql in a visual studio.net 2010 web form application. From what I have seen on the internet, you can do a console.out to any instance of a textwriter. This would be for a windows application.
How would you accomplish this task for a web form 2010 C# application?

Can the linq to sql visualizer debugger be used with Visual studio.net 2010? If so, can you tell me if there is any special setup and/or configuration I need to follow to use this visual debugger?

I am working with visual studio.net 2010 for a C# 2010 web form application. I would like to use the linq to sql visualier so I can see the generated sql while I am in debug mode.
From what I have seen on the internet, the linq to sql debug visualizer work for visual studio.net 2008.
You can find the reference for linq to sql debug visualizer in the following link:
http://www.manuelabadia.com/blog/PermaLink,guid,9160035f-490f-46bd-ab55-516b5c7545af.aspx
However does this visualizer work for visual studio.net 2010? Is there anything special I need to do to make this visualizer work for vs 2010?

You can find both dll as well as the source code of it here: LINQ to SQL Debug Visualizer[^]
It should work with VS2010 too. Just make sure you paste it in the correct directory. It looked like Scott was actively working for new versions too (based on comments). Try out.
|
|
|
|
|
Can you tell me how the server side commands you pointed me to can translate the linq statments to understandable sql statements when I am debugging?
