View 3 RepliesI am new to jquery in asp.net mvc2 and was trying to implment a simple jquery function like a show() function on my system but it keeps giving me this error:
"Microsoft JScript runtime error: Object expected"
this is my code:
[Code]....
As soon as enable script debugging I get this error. It breaks on the following block:
<table>
<tr>
<td style="width: 100px">
<asp:TextBox ID="txtRun" runat="server" OnTextChanged="txtRun_TextChanged"></asp:TextBox>
</td>
<td style="width: 100px">
<asp:Button ID="btnFilter" runat="server" Text="Show Elements" OnClick="btnFilter_Click" />
</td>
</tr>
</table>
The cursor jumps to the last tag.
The above error occurs when the following code is run:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
Within this block:
<script language="javascript" type="text/javascript">
var postBackElement;
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(InitializeRequestHandler);
function InitializeRequestHandler(sender, args) {
//set the postBackElement
postBackElement = args.get_postBackElement();
}

I have two asp.net buttons inside a template (Expand and Collapse) I want to implement a simple client side javascript function to hide the expand button after press it and show the collapse button and vice versa.
<asp:Button ID="btnExpand" runat="server" CommandName="Expand"
CommandArgument='<%# Container.DataElement("Id")%>' Text="+" />
<asp:Button ID="btnCollapse" runat="server" CommandName="Collapse"
CommandArgument='<%# Container.DataElement("Id")%>' Text="-" />
I tried OnClientClick event but I didn't know how to get the sender button and the second button from javascipt because they're in a template and their IDs will be generated.
I tried also to change their visibility from the code behind in the server (by Visible property) but the problems is the event handler will be fired after the postback and the changes will not be applied in the client.

On a page of my project, i have a gridview, i need to perform following operations with it:
1. On Page_Load i want to bind all the data (100 Rows) with the gridview.
2. On my Page i want to show only 4 records with Show More/Show Less Links.
3. When user clicks on the link, i want to show All data or 4 Rows accoeding to the link.
4. I don't want any roundTrip to the server, so plz don't suggest AJAX, i want to attain this by using Javascript.
I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.
On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.

I added a (Read More...) Div to my repeater's item template, that doesn't contain any information.
I want to add a text button or an anchor to my item template..when it's clicked it should call a javascript method that writes information to the Div and it will take the content to write as a parameter, the content will be passed as an Eval method, for example it will eval("education")...and when it's clicked again it will hide the Div
I tried various and near approaches but it all worked outside the repeater and item template tags, but if I placed the identical code to the repeater and my javascript to the head tag it won't function!
I don't want to post my code, because I'm sure it's an easy and essential trick for any developer...so I was hoping for an original example not an edit to my test code(beginners logic)
I have a gridview, which contains a template field with a button. On this button, I want to show and hide another column with this one button. I don't want to use Java Script because my site already uses a lot of this and AJAX. So, can someone show an example of some code behind, which is what I want to do on how to show and hide another column on a gridview?
View 1 RepliesI have a datalist bound to a sql source having two columns: Name and Description. The datalist contains a "Show Description" link as follows on clicking on which it calls the javascript which shows the description div.
[Code]....
The asp.net page source for itemtemplate of the datalist is as follows.The problem is that since the div id "Description" is applicable to multiple records, no matter I click on whichever "show details" link, the description of first record in the datalist is shwon and hidden since its the first div encountred by the javascript. In other words, I want a way to show/hide the description of each record in datalist indivigdually.

I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

I love JavaScript. I started out coding in ActionScript and since the syntax is almost identical, I naturally understood JavaScript. Recently, I have been learning how to use ASP.NET and MVC (which is not new to me since there are several MVC frameworks for Flash and Flex). And I'm trying to decide whether I want to learn C# or JScript... I say this ignorantly because I don't know how different JavaScript and JScript are... and C# is a completely different language all together.
1) What advantages does C# have over JScript?
2) and does it really even matter that I know and love JavaScript?
