I am currently trying to implement a small class attendance system, where the student names are taken from a database, stored in a List<Student>, and bound to a Repeater control. Each row of the Repeater contains two columns: The first is the student's name, and the remaining column contains a RadioButtonList with three ListItems (Present, Absent, Sick).Now, once the user presses "Submit", I want to be able to store their attendance status based on the user selection. However, after submission, the SelectedIndex is always 0, no matter what option is selected.

View 13 Repliesi want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?

I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupN) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).
Now My question is.
1). If user selected '1', we have to store value and user must and should select another '1' (atleast two times).
2) If user selected '1', and user trying select '2'. Giving error says "Must have select one then one record in group to combine' (will not allow) and unselect '2'.
3) If user selected '1' atleast two times, and user trying select '2'. Will allow.

Submit(Button)
When user Click the Submit (Button) the selected dropdownlist and Remarks will be displayed in the Gridview. The Gridview as follows
Dropdown Reason
0 The institution has to be improved for lot
instead of Select the Good from dropdownlist1, user wrongly select the Poor from the dropdownlist. that time POPUP screen is to displayed.(Only when user select the Poor from the Dropdownlist POUP Screen is to be displayed in that textbox type the reason and click the Submit Button). Then Gridview as follows

Then user again select the Good from the Dopdownlist1 means Previously value in the Gridview.Dropdown and reason has to be deleted in the Gridview.for that how can i do using csharp.
If the drop down list event change gridview column values to be changed.
View 1 RepliesI have a gridview that displays the data of my database. What i want is a detailsview that gives me the details of the record i select in the gridview. Both the gridview and the detailsview are on one page. I use objectdatasources to get the data from the database. In the ObjectDataSource i select the gridview-control to get the selected value. But i get the following error: An object of type System.String can not be converted to DataTable. I also tried the following:
leaving the ODS control to none and passing the value via the protected sub ObjectDataSourceDetails_Selecting:
e.inputparameter("id") = gridview1.SelectedValue
The problem is this: when i click on select in the gridview, the data won't display any data in the detailsview.How could i solve this?

View 4 RepliesI've already searched to no avail for an answer to this question:is it possible to dynamically alter the page size in a paged gridview based on data in a particular column?In other words,let's say I get data from a table that lists students enrolled in a particular course.If there are 10 students in Course "A," then I want page 1 in my gridview to show 10 records.
If there are 15 students in Course "B," then I want page 2 in my gridview to show those 15 records,and so on.I imagine that this could probably be done with a master-detail kind of set up,but let's say for the sake of argument that I don't want to go that route.
I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).
The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...
I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.
I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId
I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:
