[RESOLVED] hide span tag which is not in ContentTemplate from update panel

hi all,

I am using update panel for particular thing. But I want to hide one tab which is not in content template.

Is there any way? if not then I need to revamp existing code. Please help.

Without better explanation and code sample, i'm afraid it's not possible to help.

ASPX page

Code:

---

<tr>
                          <td align="left" style="padding-top: 20px" class="style9">
                                <div class="feedbackfrmarrowForTable">

                                <div class="programristrationformcaption1">

    {
        DataSet dsclnt_type = new DataSet();
        dsclnt_type = hpp.gethppclnttype(txtcorp_name.Text.Trim());

I want to hide txtbox txtCouNO' if value is getting 'CR'.

is it possible??? I have tried style none also.

hi all,

Please help. any idea???

Hello,

Is the txtcorp_name_TextChanged event handler actually getting called?

Have you set a breakpoint in that code and seen it execute?

Gary

hi Gary,

Yes it is called. Even hidden field is also changed value as per code.
'hdnclntType.Value = strclnttype;'
This is changing because this is in <ContentTemplate>.
because of update panel. Bt is there any way to hide my Tr tag 'trUserType'?

Ah, I see what you are saying...

Try something like this:

Code:

---

trUserType.Attributes.Add("style","display:none");

---

Gary

no luck gary... I am unable to call javascript from that.

not even:
Page.RegisterClientScriptBlock("Error", "<script language ='javascript'>alert('hi')</script>");

calling javascript from ajax update panel is my issue.

Any other idea?

To call javascript from Ajax I need to use this.
---
ScriptManager.RegisterStartupScript(upcorpname, upcorpname.GetType(), "Hi", "blockcoupon()", true);

Hello,

I am glad to hear that you got it working, but I am very confused by what you are doing :)

In Post #6 you said that you wanted to hide the TR, and the code that I provided should have done this for you.

Gary

I was unable to call JS, now I can Check following JS function.

---------------------
function coupon_block() {
var spanEvilstar = document.getElementById('<%=spanEvilstar.ClientID %>')
spanEvilstar.style.display = 'none';
trUserType.style.display = 'none';
}
-----------------------
this works fine. This line helps me call JS.
ScriptManager.RegisterStartupScript(upcorpname, upcorpname.GetType(), "Hi", "blockcoupon()", true);
