Attributes in Grid- Urgent!

Hi there!
I am using a datagrid with editlinkbutton. So when you edit a row, the values are displayed in textboxes for editing.
Now I want to run some client side Javascript code on a particular textbox. For ex, when you click on a textbox,
I want to show a datepicker by passing the next textbox value also.

Code:

---

<asp:TemplateColumn HeaderText="From Date">
    <ItemTemplate>
              <asp:Label width="80px" ID="lblfdate" runat="server" Text='<%# ConvertDate(DataBinder.Eval(Container.DataItem, "fromdate")) %>' />
    </ItemTemplate>
    <EditItemTemplate>
            <asp:TextBox width="80px" readonly="true" onclick="ShowDpicker(this,popCal,100,200,'1/Jan/1950',txtTdate.value)"                runat="server" id="txtfdate" Text='<%# DataBinder.Eval(Container.DataItem, "fromdate") %>' />
    </EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="To Date">
        <ItemTemplate>
            <asp:Label width="80px" ID="lblTdate" readonly="true" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Todate") %>' />
            </ItemTemplate>
            <EditItemTemplate>
                    <asp:TextBox width="80px" runat="server" id="txtTdate" Text='<%# DataBinder.Eval(Container.DataItem, "Todate") %>' />
            </EditItemTemplate>
 </asp:TemplateColumn>

When I click on the 'txtfdate', I am getting a client side error saying, 'txtTdate' is not declared.
I understand that ASP.NET engine creates names for the controls
in the datagrid at the runtime and send it to the browser.
My question is, how do I pass the 'txtTdate' in the 'ShowDatepicker' function of 'txtfdate'?

Can you please help me?

hi Jeba
try with the following code

Code:

---

Sub dbgrid_Edit(Sender As Object, E As DataGridCommandEventArgs)
        dgrid.EditItemIndex = CInt(E.Item.ItemIndex)
        BindGrid()
        Dim tblRow As TableRow
        tblRow= e.Item.FindControl("txtTdate").Parent.Parent
        tblRow.Attributes.Add("OnClick", "alert('hello');")
End Sub

best of luck

Hi Prasad!
I tried the following code and got an error:

Code:

---

Sub dgrid_Edit(Sender As Object, e As DataGridCommandEventArgs)
        dgrid.EditItemIndex = CInt(e.Item.ItemIndex)
        BindGrid()
        Dim txtfdt As TextBox=CType(e.Item.FindControl("txtfdate"), TextBox)
        lbl.text=txtfdt.text
    End Sub

---

Error:

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Can you please tell me why this is happening? I have double checked the names of the controls.
