CheckBox chkSelect= (CheckBox)GridView1.Rows[1].FindControl("chkSelect");
<asp:GridView
runat="server"
ID="GridView1"

How To Set An Unbound GridView Column To Invisible In Code

Apr 4, 2011

Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()

after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.

at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.

GridView With Checkbox Column. Client-side Script To Uncheck All Except Current Checkbox?

Jun 29, 2010

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.

Forms Data Controls :: Gridview Bound To DataTable - How To Enable CheckBox Column

Jul 16, 2010

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

Forms Data Controls :: AutoPostback Checkbox For Quickly Updating A Boolean Column In GridView

Jan 24, 2011

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.

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'.

Checkbox Within EditItemTemplate Of GridView Column

Jan 21, 2011

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>

Forms Data Controls :: Calculate SUM Of Gridview Column Where Template Field Checkbox Is Ticked On Button Click

Nov 9, 2010

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.

Gridview - Adding Column Of Checkbox To Its Header

Jul 22, 2011

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.

Forms Data Controls :: Link Checkbox With Bit Column, So Bit Column In SQL Database Gets Updated?

Mar 6, 2011

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.
