Having a problem with the Auto resizable text area inside my asp:content, it works fine on its own without the ContentPlaceHolder, basically I have a site.master that handles the content but its giving me problems trying to work with javascript and AJAX. Any ideas anyone...

If you mix various technologies that you don't understand, you're bound to come unstuck ? You need to define things like 'giving me problems', and tell us what you've done to try to work out what's going on

Maybe if you take a look at the code below:
Here below the textbox does not work at all for me:
<asp:content id="Content3" contentplaceholderid="mainContent" runat="Server">
function FitToContent(id, maxHeight, minHeight) {
var text = id && id.style ? id : document.getElementById(id);
if (!text) return;
var adjustedHeight = text.clientHeight;
if (!maxHeight || maxHeight > adjustedHeight) {
adjustedHeight = Math.max(text.scrollHeight, adjustedHeight);
if (maxHeight)
adjustedHeight = Math.min(maxHeight, adjustedHeight);
if (adjustedHeight > text.clientHeight)
text.style.height = adjustedHeight + "px";
}
}
<asp:textbox id="TextBox1" runat="server" onkeyup="FitToContent('TextBox1','','100')"
="" height="100" width="400" textmode="MultiLine" style="overflow: hidden">
Here below the textbox works fine:
<title>
function FitToContent(id, maxHeight, minHeight) {
var text = id && id.style ? id : document.getElementById(id);
if (!text) return;
var adjustedHeight = text.clientHeight;
if (!maxHeight || maxHeight > adjustedHeight) {
adjustedHeight = Math.max(text.scrollHeight, adjustedHeight);
if (maxHeight)
adjustedHeight = Math.min(maxHeight, adjustedHeight);
if (adjustedHeight > text.clientHeight)
text.style.height = adjustedHeight + "px";
}
if (!minHeight || minHeight < adjustedHeight) {
adjustedHeight = Math.max(text.clientHeight, text.scrollHeight);
if (minHeight)
adjustedHeight = Math.max(minHeight, text.scrollHeight);
if (adjustedHeight < text.clientHeight)
text.style.height = adjustedHeight + "px";
}
}
<asp:textbox id="TextBox1" runat="server" onkeyup="FitToContent('TextBox1','','100')"
="" height="100" width="400" textmode="MultiLine" style="overflow: hidden">
Now does this code explains enough of what I have done...Basically I don't know how to make it work with the Page.Master that defines the Content(That is my ContentPlaceHolder) which defines the look and feel of my website throughout all the web forms (Content gives them a constant look)....

I am trying to set image visibility based on some user information. Howver I always receive the following error message
Compiler Error Message: CS1061: 'XXX.SearchAcme' does not contain a definition for 'acmeBlemont' and no extension method 'acmeBlemont' accepting a first argument of type 'XXX.SearchAcme' could be found (are you missing a using directive or an assembly reference?)
This is my markup and code behind so far...any ideas what the problem could be? I can't seem to figure out what the problem is. Using FindControl did not work either and while debugging the page only seems to have 1 control in the ControlCollection. However, when you hover over "this" on a breakpoint, you can drill down and see the images.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Search.aspx.cs" src="Search.aspx.cs" Inherits="XXX.SearchAcme"
MasterPageFile="~/Center/Lobby.Master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="SponsorContent" runat="server">
<img id="acmeBlemont" runat="server" src="/acme/common/custom_images/weblet4_belmont.gif" width="170" height="45" border="0" visible="false" />
<asp:Image id="acmeVerde" name="acmeVerde" runat="server" ImageUrl="/acme/common/custom_images/weblet4_verde.gif" width="170" height="45" border="0" visible="false" />
</asp:Content>
namespace XXX
{
public partial class SearchAcme : AdvisorPage
{
public SearchAcme()
: base(ProgressNavIds.ChooseSearchOption)
{
}
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
this.acmeBlemont.Visible = true;
}
}
}

I've tried this and managed to reproduce your error. Suprisingly, removing the following attribute from your page declaration seems to resolve it.
src="Search.aspx.cs"
|
|
|
|
|
God I hate that attribute! Good to know, but I don't think I can remove it  so I have to rely on a recursive find control method, which may be a little less efficient but does the job.

I have a treeview control in my page. Both the treeviews are inside of an update panel. Issue is, when the user clicks on back button of the browser and then clicks on the root node of the tree view, I am getting an error message saying that 'There was an error in the callback."
Is there any way which I can resolve this issue? Please help. Following is my html code for the update panel:
<p><
asp:UpdatePanel ID="TreeViewUpdate" runat="server" ChildrenAsTriggers="true"><ContentTemplate> <asp:TreeView onclick="postbackOnCheck(event,'ctl00_PCMSMainContent_CreateUserWizard_TreeViewUpdate')" ID = "AvailableBusinessUnitsTreeView" runat="server" Height="100%" Width="50%" ShowLines="true" ShowCheckBoxes="All" ExpandDepth="1" OnTreeNodePopulate="AvailableBusinessUnitsTreeView_TreeNodePopulate" OnTreeNodeCheckChanged="AvailableBusinessUnitsTreeView_TreeNodeCheckChanged">
<ParentNodeStyle Font-Bold="False" /> <HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" /> <SelectedNodeStyle BackColor="#B5B5B5" Font-Underline="False" HorizontalPadding="0px" VerticalPadding="0px" /> <NodeStyle Font-Names="Tahoma" Font-Size="10pt" ForeColor="Black" HorizontalPadding="2px" NodeSpacing="0px" VerticalPadding="2px" /> </asp:TreeView> </ContentTemplate> </asp:UpdatePanel>
</p>
window.onload = function()
{
}
function postbackOnCheck(e, updatePanel) {var event = window.event || e;var o = event.srcElement ? event.srcElement : event.target;if (o.tagName == 'INPUT' && o.type == 'checkbox' &&null && o.name.indexOf('CheckBox') - 1) {"");
Error occurs on this update panel. Can anybody provide any solution for this?
Thanks

Hello,
I need help on finding the datagrid item whose radio button is clicked. I need to submit a page on which there are several datagrids with radiobuttons in it. So when a submit button is clicked I need to search and find all datagrid items whose radio buttons are clicked.
Please help.

Loop in all items and get all items which are checked.
e.g.
for (int row=0;row<=datagridview.Rows.Count-1;row++)<br />
{<br />
if(CheckBox1.Checked==true )<br />
{<br />
}<br />
}

Why your file's name must have sharp (#) character as part name of file?

I have one image field in my gridview, due to the limit of size, all the images are displayed with a smaller size, but I want to realize the following function: when the user move the mouse on the image, the image can be enlarged either in the same position (maybe more difficult, moreover, the size should be recoverd once the mouse left this field) or in a jumped new window (may be easier).
what I do not want to redicrect to a new window to display the biger image.
anyone can suggest a solution? thanks!

thanks, it is a good article, but I found difficulty in using it in my case:
my applicaiton is that I display the images in a imagefiled of a gridview, from a database, just like your article did.
so I have no idea how to use this code in my case, do you have any idea?
|

You have to bind all those javascript methods on the Rowdatabound of the gridview. I will ask you to put your query on that article discussion board if you need any help or facing any difficulties . Hope Abhishek ( Author of that article ) will reply you as soon as possible.

thanks, anyway, I use another method by using template instead of the imagefield, then I can directly change the image size with mouseover.

What is the access Specifier of that class ? You have to make it public, by default it is Internal.
