I have usedgridView for update and delete data. But I'm getting
"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" error while updating.

There is no problem in your jquery datetimepicker
Problem seems to be in :
GridViewRow row = GridView1.Rows[e.RowIndex];
Simply take separate link buttons for edit and delete as:
<asp:TemplateField HeaderText="Edit" ItemStyle-Width="150">
<ItemTemplate>
<asp:linkbutton id="lnkEdit" runat="server" CommandName="Edit" Text="Edit"/>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Delete" ItemStyle-Width="150">
<ItemTemplate>
<asp:linkbutton id="lnkDelete" runat="server" CommandName="Delete" Text="Delete" />
</ItemTemplate>
</asp:TemplateField>

I can see you are using dropdownlist for copy_id so it is better to use the below code to find the dropdownlist and fetch value from it.
DropDownList lblCopyDdl= (DropDownList )GridView1.Rows[e.RowIndex].FindControl("lblCopyId");
int Copy_Id = Convert.ToInt32(lblCopyDdl.selectedvalue);
Recommendation:: Better if you use the same code as mentioned above for other fields for getting value..
for eg
int Borrower_Id = Convert.ToInt32((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBorrowerId").Text);
Update::
If it not works then do check your e.RowIndex as mentioned in Ángel Di María's answer.
Update 2
try to fetch the date field like this
DateTime Date_Borrowed = Convert.ToDateTime((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDateBorrowed").Text);
and
DateTime Date_Returned= Convert.ToDateTime((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDateReturned").Text);

Oh you are using date picker.Try to make txtDateReturned as "ReadOnly". If it works then do comment here
mahima chand
im geeting error for ".Text" [web.UI.Control does not contain definition for 'Text']
yogi970
is this error in "txtDateReturned" textbox only,other then this all other textboxes and dropdown giving values properly? also check your "txtDateReturned" in source. i think you have miss spell the Test property to "sText". just check it

It seems that you are trying to read a cell value using index but there is no data element at that position. Suggest you to do debug and increment index value in your collection in watch window and observe data
Date_BorrowedandDate_Returned. What is data type of those column in database table?
