Exclude headers for ItemStyle- Width for gridview?

I´m trying to play around ItemStyle- Width and but this only works if i use Attribites.Add("Style"...) in my page load.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
...
}
gwActivity.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");
}
However this is not a problem. My issue is that the column headers are affected in the ItemStyle-Width:... and i do NOT want that to be the case. Can i only play around with the rows and not the headers?
<%--************************ Gridview section ************************--%>
<asp:GridView ID="gwActivity" runat="server" AutoGenerateColumns="False" OnRowCommand="gwActivity_RowCommand" CssClass="gwActivity" >
<Columns>
<asp:BoundField DataField="ActivityID" HeaderText="ActivitID"></asp:BoundField>

This is the updatebutton event

//btn.
CheckBox chkbx = (CheckBox)grow.FindControl("chkRow");
if (chkbx.Checked != true)
{
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Red;
labelErrormessage.Text = "Please Check/Uncheck the CheckBox and Click Update";
return;
}
else
{
/*--Code to update the row's record in the edatabase.--*/
??
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}
}
How do I read the row in which the button has been clicked and update its dropdownlist selected values in the database?

If you have some sort of identification data displayed in the gridview you could get the value from the row's cell like this grow.Cells[0].Text then find the record in the database and update its values.
You could also hide the id for example if this is information you dont want to show to the user. The row will still be located at index 0 but hidden.
Sample:
else
{
var record = queryDatabase(grow.Cells[0].Text);
//update record values
updateRecord(record);
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}

At the back end code, i tried to retrieve the first column and specific rows but it throw me empty. the code below is how i retrieve.
int index = Convert.ToInt32(e.RowIndex);
string sapNo1 = GridView1.Rows[index].Cells[0].Text;
string partNo = GridView1.Rows[index].Cells[1].Text;
string partDesc = GridView1.Rows[index].Cells[3].Text;
I try to show all the value for sapNo1, it throw me blank but for partNo it will show the data in the gridview.
anyone has any idea about this?
I am really appreciate your help and comment!

As your first column is a linkbutton so retrieve that as it is then find the value.
string sapNo1 = GridView1.Rows[index].Cells[0].Text; // wrong code to retrieve data from linkbutton in a gridview
Modify this as :
LinkButton linkbtn =(LinkButton)GridView1.Rows[index].FindControl("LinkButton1");
string sapNo1 = linkbtn.Text;
or
string sapNo1 =(GridView1.Rows[index].FindControl("LinkButton1") as LinkButton).Text;

You can't get the controls properties present inside TemplateField like that, you need to find the control like this:-
LinkButton LinkButton1 = (LinkButton)GridView1.Rows[index].Cells[0]
.FindControl("LinkButton1");
After this you can simply fetch the properties of this control:-
string sapNo1 = LinkButton1.Text;

you can get the link button description by the below code
protected void Link_Button_Command(object sender, CommandEventArgs e)
{
try
{
LinkButton button = (LinkButton)sender;
string name = button.ToString();
}
catch (Exception ex)
{
lbl_message.Text = ex.Message;
}
}

how to get data from a gridview

I display customers past orders in a gridview. They can press the Resend button in the last column to resend their order under the condition that the order is paid or past that status.
First the gridview:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" BackColor="White" pagesize="10"
BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataSourceID="SqlDataSource1" EmptyDataText="You have no orders yet"
GridLines="Vertical" OnRowCommand="GridView1_RowCommand">
<AlternatingRowStyle BackColor="#DCDCDC"/>
<Columns>
<asp:BoundField DataField="TD_OrdID" HeaderText="Ord" InsertVisible="False" ReadOnly="True" SortExpression="TD_OrdID" />
<asp:BoundField DataField="TD_OrdDate" DataFormatString="{0:d}" ItemStyle-HorizontalAlign="Right" HeaderText="Date" SortExpression="TD_OrdDate" ><ItemStyle HorizontalAlign="Right"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="TD_PD_PackageName" HeaderText="Package Name" ItemStyle-HorizontalAlign="Left" SortExpression="TD_PD_PackageName" > </asp:BoundField>
<asp:BoundField DataField="TD_OSName" ItemStyle-HorizontalAlign="Right" HeaderText="Status" SortExpression="TD_OSName" > <ItemStyle HorizontalAlign="Right"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="TD_InvID" HeaderText="Inv" InsertVisible="False" ReadOnly="True" SortExpression="TD_InvID" />
<asp:BoundField DataField="TD_InvPaid" HeaderText="Paid" ItemStyle-HorizontalAlign="Right" SortExpression="TD_InvPaid" ><ItemStyle HorizontalAlign="Right"></ItemStyle></asp:BoundField>
<asp:TemplateField>
<ItemTemplate>
<asp:Button runat="server" ID="btnResend" CommandName="Resend" Text="Resend" CommandArgument="<% ((GridViewRow) Container).RowIndex
%>" OnDataBinding="btnResend_DataBinding" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<RowStyle BackColor="#EEEEEE" ForeColor="Black" Font-Size="Small" HorizontalAlign="Center"/>
<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#F1F1F1" />
<SortedAscendingHeaderStyle BackColor="#0000A9" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#000065" />
</asp:GridView>
now the databinding to select the resend button when customer paid the order:
protected void btnResend_DataBinding(object sender, EventArgs e)
{
// only set button to enable when customer can resend document!
Button btn = (Button)(sender);
// enable button for status emailed, paid and closed
btn.Enabled = ((Eval("TD_OSName").ToString().Equals("closed")) ||
(Eval("TD_OSName").ToString().Equals("paid")) ||
(Eval("TD_OSName").ToString().Equals("emailed")));
}
which works fine. I am disabling the button. Maybe a better solution is to hide it instead. However this is not my concern.
now the row command to get the "ordId" value from the row where the button is pressed:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Resend")
{
// Retrieve the row index stored in the
// CommandArgument Property
int index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button
// from Rows collection.
GridViewRow row = GridView1.Rows[index];
// add code
int ordId = Convert.ToInt32(row.Cells[0].Text);
lblMessage.ForeColor = System.Drawing.Color.Green;
//lblMessage.Text = displayMessages.YourDocumentResent() + "OrdID:" + ordId;
//lblMessage.Text = displayMessages.YourDocumentResent();
lblMessage.Text = Convert.ToString(e.CommandArgument);
}
}
However to get the selected row and reading out the order identification from the row is challenging for me. I goggled this over and over and can’t see where I make the mistake.
The line:
int index = Convert.ToInt32(e.CommandArgument)
fails with
Input string was not in a correct format
If found this even on the msdn page of Microsoft?!
If I display the e.commandArgument I see: <% ((GridViewRow) Container).RowIndex %>
Can anyone help so I can get the value OrdId from TD_OrdID from the row the customer has pressed the Resend button?
Thank you in advance.

<% ((GridViewRow) Container).RowIndex %>
You're missing the #.
Try:
<%# ((GridViewRow) Container).RowIndex %>

jquery datepicker date not binding to asp.net textbox in gridview editing/updating (with masterpage)

in the code below, the string sFoodFormReceived1 always gets the value of DateTime.Now. I dont know how to make the date clicked on the datepicker UI bind to the textbox in the gridview gvReservationsWithForms.
protected void gvReservationsWithForms_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = gvReservationsWithForms.Rows[e.RowIndex];
string sFoodFormReceived1 = ((TextBox)(row.Cells[9].Controls[1])).Text;
DataTable dt = dsReservationsToBind.Tables[0];
dt.Rows[gvReservationsWithForms.EditIndex]["FoodFormReceived"] = new DateTime(System.DateTime.Parse(sFoodFormReceived1));
DataRow dr = dt.Rows[row.DataItemIndex];
var Reservation = new reservation_RoomReservationTableAdapter();
Reservation.Update(dr);
gvReservationsWithForms.EditIndex = -1;
gvReservationsWithForms.DataBind();
}

You may want to instead set the textbox to datetime.now in code, on RowEditing instead. That way, the binding doesn't interfere. It could be that...
also, you may get better performance if you do:
$("#<%= gvReservationsWithForms.ClientID %>")
.find("input[id$='tbFoodFormReceivedEditItemTemplate']").datepicker();
Instead, so you restrict the input controls to just the gridview, and not the entire page.
