Forms Data Controls :: GridView Not Firing Update Event Yet Fires Delete And Edit?
May 24, 2010
[Code]....
all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.

I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender

I have a GridView which has normal Edit/Update button. However, my GV RowUpdating, RowEditing & RowCancelingEdit is working with 2 clicks. If I am clicking it once, its not working :(
Here is the code where I am populating everything:
public partial class Testing : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string getEntity = Request.QueryString["EntityID"];
[Code]....
This is my whole code at code behind. What I am doing wrong here?

I want to Add, edit, delete and update the records using gridview with validations.
I am not using any default datasources like sqldatasource or accessdatasource.
Want to do it in code behind.
Validations should be used as if some one try to update the value as blank or do not enter characters/numbers like that.

I have a gridview that pulls data from two tables, CLIENT and PAYMENT. I want to add the edit, delete functions to the gridview for the payment portion of the table, that is to edit or delete the payments but not the client. I've manually enabled the edit, delete functions and input the queries. I've also deleted the textboxes from the templates which draw from the CLIENT table so they cannot be edited. Everything looks good on the surface until I actually go to edit or delete anything, and it has no effect.Here's the structure of the two tables:
CLIENT PAYMENT
ClientID Pk PaymentNumber Pk
FName CLIENT$ClientID Fk
LName PaymentDate
ContactNo NULL PaymentAmount
ArrivalDate PaymentDetails NULL
DepartureDate NULL
CurrentResident
Here's the update query:
UPDATE [PAYMENT] SET [PaymentDate] = @PaymentDate, [PaymentAmount] = @PaymentAmount, [PaymentDetails] = @PaymentDetails WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate
AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails) OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
Finally, here's the delete query:
DELETE FROM [PAYMENT] WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails)
OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))

I have been looking at the guide: [URL] ....
Is it possible to have an edit function, so you can edit the expanded records - fx if you want to add/correct information.
Adding a normal edit/delete button like on a normal gridview doesn't seem to work when it is nested.

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

I have a GridView which has Edit/Update functionality. However, when I am clicking it once, it is not firing. I have to click it again to fire. Rest part is working fine.
Here is the markup for my GV:
<asp:GridView ID="gvShowRegistration" runat="server"
Height="204px" Width="678px"
OnRowEditing = "gvShowRegistration_RowEditing"
OnRowUpdating = "gvShowRegistration_RowUpdating"

I am using radiobuttonlist and textbox in the gridview. I need to do operations on radiobuttonlist so that it should reflect on textbox . this is to be done after gridview_rowediting event fires i.e when we can see "update" and "cancel" buttons. I tried like this,
[code]...
here default selected value is "0" given in source.
My problem here is when I am changing the selecteditem, the corresponding action is not done.

almost done with my gridview model... Everything is working fine, bit today I noticed that my gridview delete only works on the first page of the paginated gridview. As soon as I goto the next page of my (eg) 10 rows, I can click on delete what I wan't but nothing happens. So this is what i use:
I have a gridview with a datasource, including filter- and selectparameters, paging, ipp selector etc. No code behind used.
For the delete of a row I use a imagebutton in an templatefield:
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton SkinID="ImageDelete" runat="server" ID="ImageDelete" CommandName="Delete" OnClientClick="event.cancelBubble=true; return confirm('are you sure?');" />
</ItemTemplate>
</asp:TemplateField>
In my SQLdatasource I use a Deletecommand and deleteparamter:
DeleteCommand = "DELETE FROM [TblMessages] WHERE IDtblmessages = @IDtblmessages"
<DeleteParameters>
<asp:Parameter Name="IDtblmessages" Type="Int32" />
</DeleteParameters>
it's working fine on the first page, but not on a nother page when I'm paging throught the total set.
I also use a filterexpression and selectparameters (bases on dropdownlists) to filter the gridview. This also works great, but the same ater applying a filter: the delete imagebutton doesn't work then.Just found out it's caused because something I completely forgot: the gridview resides in a updatepanel. My structure is as follows:
masterpage > content > updatepanel > gridview
