thanks it worked - my UserName textbox is embedded *inside* an <asp:login> control. Rendered on client side this became:
<br />
<input name="ctrlLogin$UserName" type="text" id="ctrlLogin_UserName" /><br />
I checked javascript the following DID add the "onmousedown" javascript handler to it:
<br />
((TextBox)Page.FindControl("ctrlLogin$UserName")).Attributes.Add("onmousedown", "alert('User name onmousedown event')");<br />

I use the following to add javascript functionality to a Textbox when I do not want the page to postback, but need an action to take place. SetBlur is the name of my javascript routine, try replacing the 'onchange' with 'onmousedown'? You just need the existing/appropriate event name.
txtTextbox.Attributes.Add("onchange", "SetBlur();")

I created a table to display an image with a caption as header. I am using a user
control for the purpose.
one use of user control is in an ordinary web page and the other use is in a page that only
an administrator can access.
Following is the rendered code seen in the view source of both web forms.
<table id="table1" border="0" width="613px" cellspacing = "0px" cellpadding="0px">
<tr style="height:20px">
<td style="height:20px; background-image:url(Images/abcd.gif); width:100%; font-size:small; color:White;
font-weight:bold" valign = "middle" > Recent logs</td></tr></table>
In one web form (ordinary web form), the image appears while in the other (admin related web page)the image
does not appear. I do not see any reason why there should be a difference in behaviour.
Please provide me a pointer as to why this could be happenning.
Thanks,

Do the webforms have different paths... i.e. are they in different directories?
What I would recommend is that you look at the source of the final pages to see what url is outputted for the image on the rendered page.

yes Ian, both webforms are in different directories.
and image is present in Image folder.
one web form is under the root and the other is inside the 'admin folder' and i have not placed any restrictions under the admin folder.
still image is not appearing! ... the text on top of the image appears but not the image!!!
|
|
|
|

The problem is when a user control is rendered images are relative to the page it is hosted in. So with your scenario since the first webform is in the root I am assuming that is where the Image folder is as well, and that is why the admin page cant find it because I am betting there is no Image folder where it is. What I would recommend is move that background style setter in the user control into a css file and link the image relative to that. css files are handled differently and an image linked in it is relative to it not that page that is linking the css file.

thanks Ian ... it worked.

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

hello all,
well please help in solving this issue......... plzzzzz. its really urgent..... Waiting for a reply

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.

Sujay

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);
Response.Redirect("Advertisers.aspx");

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?
