Arun:
First off, since you are working on an asp.net page, ASP.Net is naming the
control something other than
"TextBox1" when it renders it on the page. In order to get past this, we
need to find a way to tell
javascript the true name of the control as it is finally rendered on the
page, or just pass a reference to the
actual control.
I am not sure where you are calling the "con_date()" javascript function,
but
I will assume it is on the onchange event of "TextBox1"
Here is how I would accomplish what you are wanting:
Change the con_date() function to accept an object like so:
function con_date(txtBox)
{
var ddmmyy= txtBox.value;
var dd = ddmmyy.substring(0,2);
var mm = ddmmyy.substring(2,4);
var yy = ddmmyy.substring(4,8);
txtBox.value = mm + "/" + dd + "/" + yy;
}
(This also allows you to reuse this function for multiple textboxes on the
page as well)
Then, for your onchange event of the textbox, change it to this:
con_date(this);
That should do the trick.
Let me know how it works out.
You could also accomplish the same thing in the ASP.net code by writing the
javascript function
there and passing the TextBox1.ClientID, but I thought based on your current
code this would be easier than
trying to spit out all the javascript code from the ASP.net side.
Just for future reference, here is an example of what I am talking about:
If txtAddDDLItem.Text <> "" And hdnAddDDLItem.Value <> "" Then
Dim ddl As DropDownList = tblAdd_Employee.FindControl(
hdnAddDDLItem.Value)
ddl.Items.Add(txtAddDDLItem.Text.ToString())
ddl.SelectedValue = txtAddDDLItem.Text
ClientScript.RegisterStartupScript(Me.GetType(), "theFocus", "<script>
document.getElementById('" & ddl.ClientID & "').focus();</script>")
End If
Basically, this code uses RegisterStartupscript to add a small script that
sets the focus to a particular control.
