Web Forms :: Concatenate Checkbox Value And Textbox Value Into One Column?
Jun 16, 2010
I made a thread about getting all values of checkbox in my database, fortunately it was an easy task. I have 12 list items and the last item is "Others, specify:", wherein there would be a textbox near it for input. Obviously, it will be use to make additional data that is not included in the list.
Here's it is:
[Code]....
I made my server side code to concatenate multiples values that will be sent into my database from the user's checked items. Here it is:
[Code]....
My question is, how could I concatenate the inputted values that would be made by user on the textbox to the checkbox column on my database. I'm thinking like this:
[Code]....
Now if this is a decent method, then I would like to ask how could I set a parameter on otherattainment.Text without making a new column for it in my database. Obviously to avoid SQL Injection.
EDIT:
I just put cmd.Parameters.Add("@Others", SqlDbType.NVarChar).Value = otherattainment.Text; above, I believe this setting of parameters is only applicable if only the element will be included in the SQLCommand query and or in the database. Do you think that it has been set to parameters by adding this?

I Have a DataTable with a lot of Rows and Columns.
Some of these Rows have the Same "OrderId", actually these rows are almost the same, but I have a specific value in the "TagList" Column that I have to put in the previous row.
Making a unique Row with all the TagList values inside the TagList Column.
I'll give a example below:
Line 1:
ID: 1
Name: John
OrderId: 1500
TagList: AG75
Line2:
ID: 2
Name: John
OrderId: 1500
TagList: BG99
I wanna do it:
Line:
ID: 1
Name: Mark
OrderId: 1500
TagList: AG75, BG99
ie: Concatenate the TagList's values when they have the same OrderId.

convert the code below to LINQ, converting my project to a wseb version usimg LINQ To SQL. The project contains 10 textboxes to possibly select from, but I'm only providing the first two textboxes to simplify my question.
mySQL_Statement = "SELECT IDENTIFICATION_DATA.NSC,ITEMISCD.RNC,ITEMISCD.NSC1 FROM IDENTIFICATION_DATA LEFT OUTER JOIN ITEMISCD on IDENTIFICATION_DATA.NIIN = ITEMISCD.NIIN"
If Not ((TextBox1.Text = String.Empty) And (TextBox2.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " where "
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "IDENTIFICATION_DATA.NSC IN (" + TextBox1.Text & ")"
End If
If (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "isnull(IDENTIFICATION_DATA.NIIN) = FALSE"
End If
If Not (TextBox2.Text = String.Empty) Then
If astrixState = 0 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
ElseIf (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
MsgBox(mySQL_Statement)
End If
End If
If astrixState = 1 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " OR IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
Else
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

I have a gridview which displays following columns:
TaskID, TaskDescription, IsComplete, DateOfCompletion
Now what I want to achieve is, when user clicks IsComplete checkbox, she must enter the date of completion. So, I want a validation (client side) on DateOfCompletion if the checkbox is selected (checked). And, I also want to use Validator Callout Extender
if possible.
How can I achieve this?

I am dynamically binding a typed list to a GridView control.
The Grid View Control is in an asp.net page that is wrapped in an asp:UpdatePanel (Ajax).
The first column contains a checkbox control.
Only one checkbox may be checked in this column.
If the user checks a checkbox, all other checkbox must be unchecked.
I am trying to achieve this using client-side script without success.
In the handler for the GridView's RowDatabound event, have attempted to add an attribute to the CheckBox contained within the cell.
[code]....

I have a unbound checkbox column in the GridView control.
When i try to get the value of checkbox in the C# code the checkstate is always false.
I want to check if the Checkbox is selected in a row and get the values of all the cells in that row.
CheckBox chkSelect= (CheckBox)GridView1.Rows[1].FindControl("chkSelect");
<asp:GridView
runat="server"
ID="GridView1"
AutoGenerateColumns="False"

CheckBox Passing a specific Value to an SQL Column the object I am trying to reach is to pass a value "true" via a checkbox nested inside a GridView to a SQL Table.
This is how the control is nested inside the GridView:
<asp:GridView runat="server">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:CheckBox runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
This value should be passed when I update the GridView and I don't figure out how this can be accomplished.

Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)
Imports System.Data.SqlClient
Imports System.Data
PartialClass test
Inherits System.Web.UI.Page
ProtectedSub Page_Load(ByVal senderAsObject,ByVal eAs System.EventArgs)HandlesMe.Load
CreateDT()
EndSub
PrivateSub CreateDT()
Dim dtAsNew DataTable
Dim col1AsNew DataColumn

In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.

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'.

I have the following problem...
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and
not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.

I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
