I'm trying to give the user the ability to create a new record from the footer row and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.
The insert button that I enabled in the gridview doesn't work either...checkout the site at [URL]

View 2 Repliesiam trying to insert new record through gridveiw footer template field and its should added in sql database
i don't want to use sqldatasource, i wants to do through code.
i am using Grid view. when ever bulk data is there in Gridview, Header and footer must not be move..
how can i do that.
I'm trying to display the sum of a numeric field in the footer of my datagridview. Here's my code so far:
Code:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim TotalHours As Decimal = 0
If e.Row.RowType = DataControlRowType.DataRow Then
Dim RowTotal As Decimal = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "Hours"))
[Code] ....
The text in the footer shows up and there are no errors, but the total is always 0, so obviously my code is not actually totalling any of the values. All of the info I've found about this refers to using a datatable, which I don't know how to do. I'd be happy to learn, but I'm afraid of breaking my existing datagridview, which works perfectly well as is except for the total.

double sumRISK = 0;
foreach (GridViewRow gvr in GridView1.Rows)
{
CheckBox cb = (CheckBox)gvr.FindControl("NameCheckBoxField1");
if (cb.Checked == true)

double amountBV = Convert.ToDouble(gvr.Cells[7].Text);
if (amountBV != -1)
{
sumRISK += amountBV;
}
}
}
RISK_Label.Text = String.Format("{0:n}", sumRISK);
How do I do this? Basically, next to the page numbers in the GridView I want a link button to disable paging. This works, but I want the button inside the footer of the GridView, next to the page numbers.
View 2 RepliesOn my aspx page, I'm having troubles when I have an update panel within the footer template of a gridview. It appears to be an intermitent problem that occurs on subsequent postback when you do a delete command in the gridview. The first delete command always goes through fine (first postback). Clicking on another row to delete on the gridview (or any other button on the form) triggers this error: An error has occurred because a control with id 'ctl00$SupremeContent$grdLineNumbers$ctl09$ctl00' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.
If you click the back button in the browser, then click on another page, then come back to this page, you can delete another record. Another attempt to delete another record brings you back to the above problem. Thectl00$SupremeContent$grdLineNumbers$ctl09$ctl00 changes each time you delete, come back to the page and delete. If I disable the udpate panel, there's no errors. The reason I have the update panel is so that the user can select the relevant pipe specification (they see multiple columns using a textbox, drop down extender, panel and gridview) without the form's data being reset by the embedded gridview's selected index changed event. I've been trying to figure this out for a month now. Oh ya, this form is within a master page.
Here's the gridview code:

And this is the event that handles the delete command:

How to show sum of the column in GridView in FooterRow ?
View 1 RepliesI have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense
Code creating columns
Dim gvTownships As New GridView

Dim tmpCategory As New TemplateField
tmpCategory.ItemTemplate = New cGridViewTemplate(DataControlRowType.DataRow, "Category")

tmpCategory.FooterTemplate = New cGridViewTemplate(DataControlRowType.Footer, "Calculation")

I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.
I gave placed the the button in the gridview footer template as below:
i also have handled the row command event but when i click on the button event does not fire
The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?
