Forms Data Controls :: Finding The ID Of The Row That Has Beenchecked / Getting Error

Jan 7, 2010

I have a datagrid setup where I have a column of checkboxes setup, several informational columns for the user, and a hidden ID column. I have set up the loop to check with checkboxes have been checked, but I am having troubles finding the ID of the row that has been checked. The following code results in a "Object reference not set to an instance of an object" error:

For Each row As GridViewRow In GridView1.Rows

Dim cb As CheckBox = row.FindControl("ParticipantSelector")
If cb IsNot Nothing AndAlso cb.Checked Then
Dim productID As Integer
productID = CType(row.FindControl("ID"), Label).Text
Response.Write("You have selected " & productID & "<br>")
End If
Next

I am sure that I don't have something right here.

x Checkbox204.Checked x Checkbox205.Checked x Checkbox 206.Unchecked

Forms Data Controls :: Get Value Of Label When Checkbox Checked

Jul 22, 2010

I have a label and a checkbox that reside in a datagrid. When the checkbox is checked (OnCheckedChanged), I would like to send the Checkbox value and the label.text to a method. I don't have a way of retrieving the values. I've seen a lot about retrieving all of the values from a datagrid, (myDataGrid.Items), but am not sure how to get the value for a specific row in the datagrid.

Forms Data Controls :: Get Correct Checked Answer?

Sep 29, 2010

I am still studying to become a webintegrator and this is my private project to try and learn C# better.

I have a database with a table called Answers which holds AnswerID, Answer1, Answer2, Answer3 and CorrectAnswer + a table called Questions which holds QuestionID, QuestionNumber and QuestionText.

On a page i have a repeater that pulls the questions from the database and inside it i have another repeater with my 3 radiobuttons that pulls the 3 Answers from the database and are grouped so you can only check 1 of the radiobuttons as the user. See below:

<asp:Repeater ID="rptQuestions" runat="server">
<ItemTemplate>
<div>
<div>
Spørgsmål
<asp:Label ID="lblQuestionHeader" runat="server" Text='<%#Eval("QuestionNumber") %>'></asp:Label>

[Code]...

What i need to do, is somehow find each CorrectAnswer checked correctly in the repeater holding the radiobuttons and give 1 point for each CorrectAnswer chosen by the user (if theres 10 questions there will be 10 repeateritems with 3 radiobuttons in each one) and write this into aspnet_Profile. Problem is i have no idea how to do this since it already seems a bit complicated in my head and i haven't had much C# yet. So any help would do and notice i do not ask for the entire coding but simply a push in the right direction.

Forms Data Controls :: Allow Only One Check Box To Be Checked In The GridView?

Nov 16, 2010

I have a gridview that returns several records for the same user and each record has a column with a check box. I need to allow the user to choose only one to check. Also one check box is always supposed to be checked. What is the best way to do it? I was thinking of writing a stored procedure that checks if only one is checked, and then returns true or false. I think there is a more efficient way to do it...

Forms Data Controls :: Gridview Checked Rows Should Appear On Top In The Next Page?

Feb 17, 2011

i need to design an application in asp.net using gridview custom control. the gridview will show hundreds of records using paging with checkboxes in every row.

if the user checks 3 rows in first page of gridview which is showing 9 rows, those 3 rows should appear on top in the next gridview page and the page should display only 6 new records. ie 6+3=9

similarly if user checks 2 more rows, the next page should show 3+2 rows(from first 2 pages) on top and only 4 new rows ( 3+2+4=9)

Forms Data Controls :: Binding To Checkbox Checked When Using A Repeater

Dec 20, 2010

i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview

Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....

is this done with the itemdatabound event? and how is it done?

I have a formview in edit mode, with submit button and checkbox. I want to click the button and have it test to see if the checkbox is checked. The ID of the checkbox is "TestCheckBox".
