Web Forms :: How To Validate A Gridview Column Based On Another Checkbox Column
Apr 6, 2010
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 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'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 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"
[Code].....

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

I have a template field within a GridView to display a checkbox in edit view and some custom text in normal view.
The results of the query to populate the grid are coming back in a DataSet.
In the edit view I can't get the checkbox to accept the column that is retuning from the DataSet (which is in T/F format) as it says its not the correct type. Even if I return "true" or 1 in the column it still dosn't work.
I take it I need to convert but can't get the syntax correct in this context
<EditItemTemplate>
<asp:CheckBox ID="cbPostToFarm" runat="server" Checked='<% Bind("BOOL_COL")' />
</EditItemTemplate>

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.

On click of checkbox, I need to retrieve immediate parent span's class value:
The checkbox column is defined in an ItemTemplate as:
<asp:CheckBox CssClass='<%# Eval("ID") %>' Checked='<%# Eval("IsSelected") %>'
Text="" runat="server" onclick="CartItemCheckClicked()" />
The JS function is defined as:
function CartItemCheckClicked() {
alert($(this).parent().attr('class')); //Undefined
//alert($(this).attr('id')); //Undefined [code]....
But the result is always 'undefined'. How do I access the checkbox or parent span?

I edited my gridview template by adding an additional column of checkbox and to its header
I managed to do a checkchange for select all or none and for selecting single of multiple checkbox.
My problem here is that when I try to select all, uncheck another checkbox, the header checkbox is still checked and the unchecked checkbox becomes checked again.
If i did not check my header checkbox and just check it normally, its fine.
