Checkbox column not selectable
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.
View 3 RepliesCheckBox 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.
I have a gridview control
i add template column dynamically to gridview
like this in a function in AddColumns button clickevent
gv.Columns.Clear()
Dim chkCol As New TemplateField
chkCol.ItemStyle.Width = 20
chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center
gv.Columns.Add(chkCol)
2)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim chkbox As New CheckBox
chkbox.ID = "chkSelect"
e.Row.Cells(0).Controls.Add(chkbox)
End If
End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click
Dim linkId As String
Dim summary As String = ""
'Enumerate the GridViewRows
For index As Integer = 0 To Me.gv.Rows.Count - 1
'Programmatically access the CheckBox from the TemplateField
Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox)
If cb IsNot Nothing Then
If cb.Checked Then
linkId = Me.gv.DataKeys(index).Value
End If
End If
Next
Me.Page.Title = linkId
End Sub
But here i am not getting Check box even i used find control. how i get checkbox
I need to add a checkbox column to my data and do it programmatically. I've seen a lot of other posts that address this, but can't get it to work in VB.

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 form with several checkboxes....i want to insert the selected checkbox values in to a single column in the sql database..
View 4 RepliesI have a gridview that includes a checkbox colum (Item Tempate).I need to be able to select row but when mouse is over checkbox column it should not be clickable. Is this possible?Think of it as an Inbox type gridview where checkbox is used for deleteing messages but when you click on subject or name it will show the message. I need the same functionality.
View 7 RepliesIn 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 a gridview were one of the colunms has a checkbox for deleting that row. When the user open the page the delete button is set to enable = false. If the user checks one box the delete imagebutton is disable = false. That works, now I need to add Javascript to enable the Delete button if the user selects checkAll, how do I do that?
View 2 RepliesI 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 am trying to implement multiple choice questions within my web application. I have datalist within a datalist. First datalist contains questions, second datalist contains choice, only one choice should be selectable at a time. I am using radio button. Even though I have set radio button's GroupName property, I can't make them selectable one at a time.
View 1 Replies me how can i make each cell of a gridview selectable(Web Project)?
Basically my requirement is to do some action when i select a cell without having postback. And I am not allowed to use ajax or jquery here. how can i do this using only asp.net gridview and javascript(possibly).
For Example, i want to make some control visible/invisible or enable/disable based on the cell selected.
Does anyone know of a way to display a grid where the user can select multiple rows from a single column to copy to the clipboard, as opposed to an html table where the text can only be selected by rows. In my work, we do a lot of copy/pasting of chunks of data. I would like to migrate our processes out of SQL mgmt studio and into a browser, but I need an html table that will behave more like a spreadsheet and less like a paragraph.
(see illustration below if you can't understand what I'm talking about)
How do i make the default entry in a dropdownlist not selectable? Right now I have a drop down and the users are able to select the default option that says (Select one)...here is what my code look like. I hard coded my options in there cause the list is really short and won't change ever. Right now, users can select the default entry and add it whatever list they are generating on the page...and I would like to make that default visible but not selectable.

I want to display some search results on an ASP.NET webform. I want the user to be able to single-select one of the items returned.
My search results will be in the form of a list of objects, so ideally, I'd like to be able to bind a such a list.
The ListView control sounds promising, as that is certainly what I would use in a WinForms application, but I haven't seen any evidence that the ASP ListView is selectable. Even the GridView control seems to render into html as a static table of data, in which you cannot select.
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.
I have a gridview setup and have the select button enabled. I also have a gridview that doesnt have a select button enabled..
On them both, if its possible, i would like to make the row itself selectable instead of just enabling the select button.
I am adding columns dynamically to gridview as [URL] ....
I am adding checkbox and trying to add handler but it is not getting fire

Below is the snapshot of the gridview .i need to insert checkbox in my first coloumn of gridview before Transaction id.on checking the checkbox of a particular the status column of that particular row should changed from "Pending to "Sucess"...
View 1 RepliesScenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
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.
