Hi all,
I am working on a ASP.NET project where i am displaying several images and their details, both coming from a database table. What i want is i am calling a javascript when some one moves the mouse cursor over the image, for that i have designed the javascript but the javascript depends on the id (stored as a coloumn in the same table) of the row containing the image on which the cursor is positioned. I have taken the id field in an hidden field and tried the following code
protected void DataList1_ItemCreated(object sender, DataListItemEventArgs e)
{
ListItemType elemType = e.Item.ItemType;
if ((elemType == ListItemType.Item) || (elemType == ListItemType.AlternatingItem))
{
CheckBox cBox = (CheckBox)e.Item.FindControl("chkSel");
Image pimg = (Image)e.Item.FindControl("Image2");
HiddenField hf_Pid = (HiddenField)e.Item.FindControl("hfPid");
pimg.Attributes.Add("onmouseover", "showButton('"+hf_Pid.Value+"');");
cBox.CheckedChanged += new EventHandler(OnChangeHandler);
}
}
The idea is to find the value in the hidden field that is coming from the database and then pass it to the showButton() function in the javascript. But this doesn't seemed to work. Please help me in accomplishing this task. Your help will be highly appreciated. Thanks in advance
Regards
Sujay

hhmmm.
I have done the same thing and found an issue with making it work. I cannot update dynamically via javascript, any asp.net control on a page that was not created by code behind. If the control is cast on the aspx page, I cannot touch it by referencing the name dynamically in javascript (odd, but repeatable behaviour). If I create the control via code behind instead, the exact same routine in javascript will work. Note, the method that does not work, will not throw errors either. It just ignores your code (so it seems).
Try creating the checkbox in the onload routine instead and see if it works that way (give the table or container the checkbox exists in an ID so you can add the checkbox with code behind instead). You are on the right track, absolutely. I think its the weird behaviour that is hanging you.

Which thing is not working properly?
Tell whether the onmouseover event is not working.
Or The onmouseover is working but the id in the hidden field is empty. if so, then you can get the value of the hidden field in ItemDataBound event only.
|
|
|
|
|
I realize in reviewing this that there are several more caveats to it that cause this issue. I think I will cut bait here and run. Sorry.
|
|

|

Thank you Ramesh,
Actually the problem is that the hidden field value that i am trying to pass to the javascript is always showing null, but the hidden field is having the value when viewed from the source of the page from browser.
I wonder if the ItemDataBound event will allow me to add the javascript to the imgage tag.

Have problem with getting check box in database checked when a current part of admin is approved or not approved here some code.
getting error with bool value
protected void ApproveAdvertiser()

DataService ds = new DataService(int.Parse(ConfigurationManager.AppSettings["ConnStr"]));
Advertiser adv = new Advertiser();
adv.AdvertiserId = 0;
ind_approved.Checked = adv.Approver;
ds.approveAdvertiser(adv, ValuePassedIn);

I don't see any meaningful code here. What is the exact error, and what line throws it ?
What are the methods you're calling ?

I agree with Christian here, not enough meaningful code to help. Show us the code that you use to actually write the value to the db.
The typical mistake however here is that you are trying to write a true/false back to the database when the database requires a 1/0 value instead (real Boolean not that fake true/false stuff  ).

I have some client side vbscript and I need to pass it some data from the server side code behind file. On the server side it is a text session variable. How do I pass that value to the client side vbscript?
|
|
|
|
|
Write your session variable to the script
You can use something like this in your script <%= Session("SessionVar") %>
Example:
<script type="text/javascript">
alert('<%= Session.SessionID %>')
</script>

I can use a session variable in my vbscript but I get an error when I add the following line in the html to reference the code behind file.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
The error is:
The Session does not exists in the current context.
I want to use the code behind file, so how can I get this error to go away?

Could you explain what you mean by this, I'm taking it as it works fine through debugging against your local environment and against a server environment whilst running a browser on that server, but not when browsing from another computer against the server?

thank you for your response,Yes that i sexactly what the problem is.

To solve this problem do this works:
1. Create directory “C:\Windows\SysWOW64\config\systemprofile\Desktop ” (for 64 bit Windows) or “C:\Windows\System32\config\systemprofile\Desktop ” (for 32 bit Windows)
2. Set Full control permissions for directory Desktop (for example in Win7 & IIS 7 & DefaultAppPool set permissions for user
“IIS AppPool\DefaultAppPool”)

This error might be occured in different scenarios
(1) if you try to access the Excel cells which is not existis like Cells[-1,0].
(2) When you try to insert an Excel Worksheet before a worksheet and after another worksheet using the Sheets.Add() method
(3) When you write the content of a two dimentional array having some special chanracters like '=''%' in the array elements into some range of cells.
Check whether the above scenarios occured in the server side.
Also instead of using Microsoft.Office.Interop.Excel.ApplicationClass in your automation code, try to use
Microsoft.Office.Interop.Excel.Application class to create the Excel application instance.
Hope this will help you.

Hi All
I have created a web application where I load controls on different callbacks. So When User click on a button "Security" I have to load a security control using ajax which works fine. The problem I am facing is the following.
in Security Control I have one javascript function say ShowDetail(){ some js code here } which is required to be called when this control is loaded. When the control loads it does nto trigger , for testing I placed a button on contrl and on click I call ShowDetail() and it says that undefined function.
on another control I have Javascript with a variable say var id = '<%=this.ClientID%>'
so when I try to access "id" variable after loading that control Javascript rasie error with id is undefined.
Can any one help me out with these issues ?
Best Regards
