Forms Data Controls :: Store Attendance Status Based On The User Selection?

Jan 26, 2010

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.

Forms Data Controls :: GridView Page Reset Based On DropDown List Selection?

Jan 3, 2011

i 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 am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.

Forms Data Controls :: Checkbox Selection Based On Group Column Values In Gridview?

Jul 28, 2010

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.

4) If user selected '1' atleast two times and selected '2' one time, trying to select '3'. will not allow user to select '3'.

Forms Data Controls :: Details Won't Display After Selection In Gridview

Feb 26, 2010

I 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?

Forms Data Controls :: Dynamically Alter The Page Size In A Paged Gridview Based On Data In A Particular Column?

Dec 14, 2010

I'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.

Forms Data Controls :: Dynamic Gridview With Dropdownlist / Dynamically Set The List Values Based On Parameters (of The Row They Are On)

May 28, 2010

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:
