}
You need to check the e.NewValues dictionary for updated data.
I've a sample below, the GridView Template is bound to CategoryName.
OnRowUpdating is fired when the 'Edit' button is clicked.
In the RowUpdating event handler, it fetches the CategoryName data to which the textbox is bound to.
Note: Instead of using TextBox in normal mode use Labels.
<asp:GridView ID='GridView1' runat='server' DataKeyNames='CategoryID' OnRowUpdating='HandleOnGridViewRowUpdating'
DataSourceID='ObjectDataSource1' AutoGenerateColumns='false'>
<Columns>
<asp:CommandField ShowEditButton="true" />
<asp:TemplateField>
<HeaderTemplate>
<asp:Label ID='CategoryName' Text='Category' runat='server'></asp:Label>
</HeaderTemplate>
<ItemTemplate>
<asp:TextBox ID='CategoryNameTextbox' Text='<%# Bind("CategoryName") %>' runat='server'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
code-behind:
public void HandleOnGridViewRowUpdating(object sender, GridViewUpdateEventArgs e)
{
if (e.NewValues["CategoryName"] != null)
{
String newCategoryName = e.NewValues["CategoryName"].ToString();
// process the data;
}
}

Use
OnRowCommand = "OnRowCommand"
Now when any action happen on the grid the OnRowCommand event is executed.
protected void OnRowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow gvRow = GridView1.Rows[index];
}
More Info
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"
OnClick="MyButtonClick" />
</ItemTemplate>
and your method
protected void MyButtonClick(object sender, System.EventArgs e)
{
//Get the button that raised the event
Button btn = (Button)sender;
//Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}
everyone. I needed your help. I am creating an online workshop registration system. I have a inicale gridview that show the all the available workshop for registration during the festival time. I am using a session and check box to get the workshop that the person want into the "shopping cart" on the next page. what I needed to do is after righting a incial order written to an order table in my SQL database. What I am having issues with is when it write the registration data that is stored in an other gridview for the shopping cart. I am writing each row as a new entry into a order detail table. when I do this the program does something very odd. It seem to write all the data from the a gridview that holds all the workshop information on the first page.
code for writing the shopping cart row to the order detail table:
protected void btn_Submit_Click1(object sender, EventArgs e)
{
foreach (GridViewRow row in Basket.Rows)
{
Label lblCatCode = (Label)row.FindControl("lblCatCode");
Label lblTitle = (Label)row.FindControl("lblTitle");
SqlConnection conBasket = new SqlConnection("Data Source=JONS\\SQLEXPRESS;Initial Catalog=OFFFV2;Integrated Security=True");
SqlCommand cmdBasket = new SqlCommand("Insert into OrderDetail(OrderID,CatalogeCode,Title)Values(#OrderID,#CatCode,#Title)", conBasket);
cmdBasket.Parameters.AddWithValue("#OrderID", lblOrderNumber.Text);
cmdBasket.Parameters.AddWithValue("#CatCode", lblCatCode.Text);
cmdBasket.Parameters.AddWithValue("#Title", lblTitle.Text);
try
{
conBasket.Open();
cmdBasket.ExecuteNonQuery();
conBasket.Close();
}
catch (Exception ex)
{
lbl_Error.Text = "A database error has orrued. <br <br />" + "Message: " + ex.Message;
}
}
}
Here is the code for the gridview
<asp:GridView ID="Basket" runat="server" AutoGenerateColumns="False" DataKeyNames="WorkshopID" DataSourceID="BasketData" EnableViewState="False" ShowFooter="True" OnRowCreated="Basket_RowCreate" CellPadding="4" ForeColor="#333333" GridLines="None" >

I understand that my last post was unclear and was closed. I am at a loss as why the program is doing what it is doing. I am wondering if it is in connection with the way I get the data from the first gridview to the shopping cart.
Here is the code for the session for the selected row
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btt_Select_Click(object sender, EventArgs e)
{
var selectedWorkshop = GridView1.Rows.Cast<GridViewRow>().Where(row => ((CheckBox)row.FindControl("RegisteredWorkshop")).Checked).Select(row => GridView1.DataKeys[row.RowIndex].Value.ToString()).ToList();
if (Session["cart"] == null)
{
Session["cart"] = selectedWorkshop;
}
else
{
var cart = (List<string>)Session["cart"];
foreach (var workshop in selectedWorkshop)
cart.Add(workshop);
Session["cart"] = cart;
}
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox cb = (CheckBox)row.FindControl("RegisteredWorkshop");
if (cb.Checked)
cb.Checked = false;
}
}
protected void btt_CheckOut_Click(object sender, EventArgs e)
{
if (Session["cart"] != null)
Response.Redirect("Checkout.aspx");
}
}
The code for the select gridview from where the registrant select from the various workshops:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource3" CellPadding="4" DataKeyNames="WorkshopID" ForeColor="#333333" GridLines="None">

I may be wrong but it looks like your variable naming is off (confusing basket and cart?).
You might need to do something like this:
protected void btn_Submit_Click1(object sender, EventArgs e)
{
var Basket = (List<string>)Session["cart"]; // ADD THIS LINE
foreach (GridViewRow row in Basket.Rows)
{

ShowRow is a boolean value that gets set in GetUnitOfMeasure function (not copied here) based on these conditions.

My problem is that when I debug it, say I add the breakpoint to this event, it is never fired, is like if it does not see the event for some reason... Can anyone see what the problem may be? This is the mark up of the grid at the top
<telerik:RadGrid ID="radGrid" ShowFooter="true" ShowHeader="true" CaptionAlign="Left"
runat="server" ForeColor="Black" CellPadding="4" AutoGenerateColumns="False"
CssClass="Grid" Width="100%" GridLines="None" OnRowCommand="radGrid_RowCommand"
OnNeedDataSource="radGrid_NeedDataSource" AllowPaging="True" AllowSorting="true">
<MasterTableView DataKeyNames="ApartmentID,ApartmentTypeID">
<CommandItemSettings ShowRefreshButton="true" ShowAddNewRecordButton="false" />
<Columns>
<telerik:GridTemplateColumn>
<ItemTemplate>
<asp:LinkButton ID="Delete" Text="Remove »"
CommandArgument='<%# Eval("ApartmentId") %>'
CommandName="RemoveItem" CssClass="Button" runat="server" />
</ItemTemplate>
</telerik:GridTemplateColumn>

You have a linkbutton inside an itemtemplate, add a handler for OnClick on the linkbutton itself and the event will surely be fired.
For example:
protected void LinkButton1_Click(Object sender, EventArgs
{
LinkButton button = sender as LinkButton;
Apartments apartAdmin = new Apartment();
bool deleted = apartAdmin.Delete(int.Parse(button.CommandArgument.ToString());
if (deleted)
{
radGrid.Rebind();
}
}
