I have a gridview that is not bound to a database source. I used a middletier written by self to return a dataset(with 1 datatable) which i now bind the datatable to the gridview.
The problem is that, i want the gridview to have Edit and update option to edit the gridview row and update.

Hi aransiola,
You should set 'AutogenerateEditButton' Property of grid view to true.
Then you should handle RowEditing and RowUpdating Events.
Inside RowEditing Method You should specify which row is going to be edit.
Inside RowUpdating Method You should call your update function for that row.
Try this..

Thank u.
Pls one of my field in the gridview is a date field, I want to use a datepicker control in one of teh column instead of a textbox control when editing the grid
|
|
|
|
|
You need to add an 'Edit Item Template' inside the grid view.
For that
2.Inside 'edit item template' put ur datepicker control(whatever it is).
<asp:TemplateField>
<EditItemTemplate>
<asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>
</EditItemTemplate>
</asp:TemplateField>

Thank you for your response on this problem. Please my
Row_Updating not updating old value with new value. Remember i am using a datatable returned from my middle tier as the datasource to the gridview. If i was using the sqldatasource, i would not have this problem, but the problem im solving requires that i should use a datatable. One user will create the detail table while the other user will use the information from the first user, then update that with his own and save it into another table. Sorry for labouiring you people with this details.
See my code below
Protected Sub grdPhases_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles grdPhases.RowUpdating
If Not Session("biddetail") Is Nothing Then
oDT = Session("biddetail")
End If
grdPhases.DataSource = oDT
If e.NewValues("PhaseCost") IsNot Nothing Then
e.NewValues("PhaseCost") = Decimal.Parse(e.NewValues("PhaseCost").ToString(), Globalization.NumberStyles.Currency)
Else
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If e.NewValues("StartDate") IsNot Nothing Then
lblPhaseCost.Visible = False
Else
lblPhaseCost.Text = "Enter the Start Date for this phase"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If e.NewValues("EndDate") IsNot Nothing Then
lblPhaseCost.Visible = False
Else
lblPhaseCost.Text = "Enter the End Date for this phase"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If Not IsDate(e.NewValues("StartDate")) Then
lblPhaseCost.Text = "Invalid Start Date"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
Else
lblPhaseCost.Visible = False
End If
If Not IsDate(e.NewValues("EndDate")) Then
lblPhaseCost.Text = "Invalid End Date"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
Else
lblPhaseCost.Visible = False
End If
'Dim strFind As String = "PhaseCode='" & e.OldValues("PhaseCode") & "'"
'Dim RowFound() As DataRow = oDT.Select(strFind)
'For j As Integer = 0 To RowFound.GetUpperBound(0)
'only 1 row
e.OldValues.Item("Description") = e.NewValues.Item("Description")
e.OldValues.Item("StartDate") = e.NewValues.Item("StartDate")
e.OldValues.Item("EndDate") = e.NewValues.Item("EndDate")
e.OldValues.Item("PhaseCost") = e.NewValues.Item("PhaseCost")
'Next
Session("biddetail") = oDT
'Set EditIndex=-1 to exit editing mode and rebind teh gridview to the
'datasourecto refersh
grdPhases.DataSource = oDT
grdPhases.EditIndex = -1
End Sub

Hey
I am creating a site which allows users to customise their own area (no it is not a myspace clone - it isnt even social networking based).
I was just wondering if any one with experience could help me with my problem:
When creating the themed pages do I:
a) Dynamically create new pages for each user when they sign up
b) Dynamically create pages when a user requests to see the themed area
c) Both these ideas are complete twoddle and there is a better way of doing things (please expand and dont just say your an idiot Dan)
Thanks
Dan

I dunno the root cause of the problem, but I have a quick solution.
Delete the ASPNET user account and then run aspnet_regiis with the -i switch.

HI
Re install the IIS. I think this problem is from IIs only. This is as per my knowledge.

Hey,
I have a Grid view with four bound columns and one bound button column. When the bound button column is pressed I want to catch it and trigger some code. The code that I want to trigger requires the unique id of the column which I also display using the first bound column. Now I know I could put the id column in a template column and use findcontrol() to get its value but I was hoping I could just leave it as is.
I am using the RowCommand event to catch the press of the button. Does any one know the simplest and best way to do this. I have attempted to use datakeys but they dont seem to work in the right way.
Thanks

Use a Template column, place a normal button, set the CommandArgument to the databound filed name using following syntax <%#Eval("COL_NAME")%>. In the row command of the gridview get the command argument value from the event argument.

Thanks for that. But is there no way to grab a boundcolumns values instead. So I dont have to use the template column?

Hi,
I am using a .net adrotator control to handle banner etc ads throughout a site. A new new advertiser has come along and their ads are to be served via doubleclick. The problem I am having is that they have only given me code which in turn will request the ad and the hyperlink from their servers. This of course won't work with my setup.
<SCRIPT SRC="http://ad.uk.doubleclick.net/adj/N4419.xxxx/B2303055;sz=630x90;abr=!ie;ord=[Timestamp]?"></script>
<NOSCRIPT>
<a href="http://ad.uk.doubleclick.net/jump/N4419.xxxx/B2303055;sz=630x90;abr=!ie4;abr=!ie5;ord=[Timestamp]?">
<img src="http://ad.uk.doubleclick.net/ad/N4419.xxxx/B2303055;sz=630x90;abr=!ie4;abr=!ie5;ord=[Timestamp]?" width="630" height="90" border="0" alt=""></a>
</noscript>
Ive tried putting the src & href code into my xml file but it doesnt work.
Anybody had anythink similar?
Thanks in advance

Everything works fine except that when changing my selected data from my dropdown I noticed that the new loaded data in my gridview was on the same page that was when you were in the previous data, How to bring it up to the first page when a new selected data from the dropdown.

All columns, visible or invisible are accessed in the same way programmatically. The invisible columns are just hidden from the design and runtime view, but still exist in the object.

Hi all,
My apologies if this is an easy one (v.new to this!) but I get the following error when clicking edit a datagrid with a dropdownlist.
'System.IndexOutOfRangeException: StatusID'
In my datagrid I'm calling functions in VB. One to get the status and populate a Dataset & one to get selected index so I can set the initial value of the dropdownlist.
I then have the update sub to declare the dropdownlist and and update the database.
Would anyone be able to point me in the right direction?
Many Thanks
Rob
