Solution 1

pass textbox object as parameter to method like :

protected void txtnextduedate_TextChanged(object sender, EventArgs e)
{
    updatecareplan(sender);
}

and update method defination like:

private static void updatecareplan(object sender)
{
    TextBox txt = (TextBox)sender;
    GridViewRow row = (GridViewRow)txt.NamingContainer;
    int index = row.RowIndex;
    // do your code here
}

this may help you

DateTime testdt = DateTime.ParseExact(txttestdate.Text, "yy/dd/MM", null);
now am getting problem on this line...
string was not recognized as valid datetime

vishal.shimpi 12-Mar-13 3:05am

try using....
DateTime testdt = Convert.ToDateTime(txttestdate.Text);

ujali 12-Mar-13 3:09am

still it is giving the same error

vishal.shimpi 12-Mar-13 3:13am

whats the value is in your text box : txttestdate.Text

ujali 12-Mar-13 3:17am

now there is no value in that textbox...
this is the field in grid..

<asp:TemplateField HeaderText="Current Date">
<itemtemplate>
<%--<asp:Label ID="Label9" runat="server" Text='<%# Bind("Current_Test_Date") %>'>--%>
<asp:TextBox ID="txttestdate" ClientIDMode="Static" runat="server" Text='<%# Bind("Current_Test_Date") %>'
CssClass="textboxInGrid" AutoPostBack="true" Width="50"
ontextchanged="txttestdate_TextChanged">
<asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txttestdate"
Format="yy/dd/MM">

vishal.shimpi 12-Mar-13 3:22am

okk.. so find the format of date which is appearing in your gridview (eg dd/MM/yyyy or MM/dd/yyyy or MM/dd/yy) and use DateTime.ParseExact() method and pass the same format as the second parameter in ParseExact method...

ujali 12-Mar-13 3:20am

<asp:TemplateField HeaderText="Current Date">
<itemtemplate>

<asp:TextBox ID="txttestdate" ClientIDMode="Static" runat="server" Text='<%# Bind("Current_Test_Date") %>'
CssClass="textboxInGrid" AutoPostBack="true" Width="50"
ontextchanged="txttestdate_TextChanged">
<asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txttestdate" Format="yy/dd/MM">

ujali 12-Mar-13 3:21am

this field is in item template

vishal.shimpi 12-Mar-13 3:24am

is your date is appearing like "13/12/03" where 13 is year, 12 is day, and 03 is month

ujali 12-Mar-13 3:25am

DateTime testdt = DateTime.ParseExact(txttestdate.Text, "yy/dd/MM", null);

it is also giving the same error

vishal.shimpi 12-Mar-13 3:33am

ok.. just tell me whats the date is appearing in the txttestdate...

ujali 12-Mar-13 3:36am

null

vishal.shimpi 12-Mar-13 3:42am

if u get the value of txttestdate.Text is null then it will not be converted to datetime type

ujali 12-Mar-13 3:29am

this is also having textchanged event

protected void txttestdate_TextChanged(object sender, EventArgs e)
{
updatecareplan(sender);
}
so as i am taking cursor in that field it is giving error

vishal.shimpi 12-Mar-13 3:36am

what the error is occuring?

ujali 12-Mar-13 3:37am

String was not recognized as a valid DateTime.
at this line
DateTime testdt = DateTime.ParseExact(txttestdate.Text, "yy/dd/MM", null);

ujali 12-Mar-13 3:45am

so what should i do?

vishal.shimpi 12-Mar-13 4:34am

check the condition like

DateTime testdt;
if(txttestdate.Text == "")
testdt = Convert.ToDateTime(null);
else
testdt = DateTime.ParseExact(txttestdate.Text, "yy/dd/MM", null);

try this one

ujali 12-Mar-13 4:59am

still giving the same error

vishal.shimpi 12-Mar-13 5:05am

Hi ujali,
i dont know whats wrong you are doing..
becouse

//assumed that txttestdate.Text = "13/15/03"
DateTime date = DateTime.ParseExact("13/15/03", "yy/dd/MM",null);
this line is working perfect at my end..

vishal.shimpi 12-Mar-13 6:15am

Is your problem solved?
