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 RepliesI am currently adding checkbox functionality to a system. I would like to check a group of users and add them into a db table. I currently have the administrator values flowing into the db table fine but it will not insert the empID into the table from the gridview. Here is my code:[Code]....
View 5 RepliesI am buidling a support call system that allows people to submit support tickets and then an engineer can respond to them.Support tickets are submitted from a formview to a database. Then the engineer looks at them from his own page which shows that particular call in a formview, he adds his comments and hits update.What I want to do is be able to add more than one set of comments should the engineer have to make more than one entry and for that I would like the control to add a column to my database table.Is there an easy way for this to be done?

Something like that. My SQL syntax isn't very well. I hope i can tell what i want..
What REALLY want is, When i click a button, showing in Gridview with second SQL , BUT only i selected in CheckBoxList.
Is there any way adding to parameter in SQL? How can i do that?
I have a gridview in my aspx page, which is filled with data from generic list.
I want to add a checkbox and a link button in the grid, so that users can select the row and when users click on the link button, a new page is loaded with the items in the selected row.
I have a checkbox inside a repeater like below..I'm having trouble figuring out how I need to tie the onclick event to a javascript function..I know I need to use somthing like
butSubmit.Attributes.Add("onClick", "return confirmSubmit();") but Since my checkbox is inside a repeater and I'm using master pages. I'm not sure how I need to use the findcontrol to so I can call the Add method?
I need to add an onclick to the ChkAll checkbox

Checkbox column not selectable
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.
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
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

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 RepliesI'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this:
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like:
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Totals 1 1 2
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file

i am kind of new in the .net world. I would like to know how you can add a link column with an image to a datagriid.
P.S. i am using Visual studio 2005.
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row
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 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 need to add a sum total for each column in my gridview and I need to do this programmatically because my gridview mark up does not contain any column mark because the columns themselves are added programmatically.
This there away to do this on the row data bound event? If so how do you do it? I have 10 columns which each need to have a total.
i need to calculate the total price in a column in a gridview1. How do i do so?
My column in the gridview is like this, it is at cell 5
Price
$1.00
$3.50
$4.00
I'm using VB btw, i dont understand C#.
I have an accessdatasource that pulls several columns from my users table including [userID]. Then I have a gridview that displays all this information by autofilling the columns. Finally I have added a column that I want to link to viewUser.aspx?userID=####. The #### would of course be from the query.
Here's my column that I've added:
<Columns>
<asp:HyperlinkField datatextfield="View User"
datanavigateurlfields="userID"
datanavigateurlformatstring="viewUser.aspx?userID={0}"
headertext="Link"
target="_blank" />
</Columns>
This is my first time using this so I'm not sure what's wrong. I don't understand the '{0}' part and that's also where the problem lies. On the viewUser page when I print the querystring("userID") it just shows {0} as expected. How do I get my userID in there?
am binding a gridview to datatable ...and now i want to add a linkbutton/hyperlink as one of the columns in gridview (similar to checkbox field) ...am adding the Lbtn inside a template field ,but i want that column to come as last column ..but its coming as first column,,,how to acheive that??

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.
