i have a masterpage and other pages. i want to use findcontrol method to find a textbox (not on the master page) to check whether it is empty or not.
my code is as folows;
Dim myContentPlaceHolder As ContentPlaceHolder = CType(Master.FindControl("MainContent"), ContentPlaceHolder)
Dim UpdatePanel1 As UpdatePanel = CType(myContentPlaceHolder.FindControl("UP1"), UpdatePanel)
If I use the FindControl Method on an .aspx page (without master page), it finds the desired control no problem. When I use a Master Page then it will not find it even though it exists. why is this?
[Code]....
Here is my structure of master page.
[MasterPage <- Child Page <- Content Page]
1) In MasterPage,i have ContentPageHolder1
2) In Child Page, i add linkbutton into ContentPageHolder1 and create ContentPageHolder2 section
3) In Content Page, select Child Page as master page and try to load the child page link button from page load event but fail
and Checked the current master page name by using [Master.MasterPageFile], it will return MasterPage.
using VS 2005,Ajax and master pages This is how i'm adding controls to placeholder
[Code]....
here is code to read value but it returns null
TextBox text = PlaceHold1.FindControl("TxtSlotName0") as TextBox;
aspx page follows
<%@ Page Language="C#" MasterPageFile="~/Admin.master" AutoEventWireup="true" CodeFile="SlotAlloc.aspx.cs" Inherits="SlotAlloc" Title="Untitled Page" %>

How can I access to the CancelPushButton ?

I am porting my simple Role Based Auth to ASP.NET. It requires this check on each page:
[Code]....
If put in each page's OnLoad, it works fine. But when I add it to the masterpage, it doesn't work. Is there something about the ServerVariables or Session Object that would prevent using those in a masterpage? Is it an issue calling my class from a materpage?
i have my NEWS BAR script code in my home Page which inherits from masterpage like this :
<asp:Content ID="content1" runat="server" ContentPlaceHolderID="mainholder" >
I put common(for all my content pages) js to head section at my masterpage.
<head runat="server">
<script type="text/javascript" src="../Scripts/jquery-1.4.1.js"></script>
<script type="text/javascript" src="../Scripts/jquery.corner.js?v2.11"></script>

I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage.

I've just discovered that the X-Requested-With header in IE is always "XMLHttpRequest, XMLHttpRequest" instead of just "XMLHttpRequest". I found the reason in MicrosoftMvcAjax.debug.js at line 280 (MVC 2.0). Seems there is no need to add this header again as it is already done in Microsoft AJAX Library. And because of this IsAjaxRequest extension method doesn't work anymore if there is no X-Requested-With param in the request body. And this make X-Requested-With header useless in IE.
In Firefox there is no problem as it doesn't append but replace the existing header value. Not tested in other browsers.
I am trying to use YAF with Umbraco. The newest version out changed enough where the old integration methods don't seem to work. I have gotten everything fairly far on my own but I have hit a brick wall with this error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have a feeling that YAF is not starting up the database. In previous versions of YAF there was an INIT module that you loaded in your web.config file. This module is no longer there (YAF.Base.YAFInitModule).
I'm unable to set Comments property of a MembershipUser type objects.
E.g.
MembershipUser mu = Membership.GetUser(username);
mu.Comment = "someComments";
I'd expect this to set the Comment property of mu object to "someComments" and write changes to the database.
Later, I do a following check:
mu.Comment == "someComments";
Comment property is set to null. Is there anythign that I need to change in a web.config or...?

I was wondering if it is possible to find a control in a standard web form that is using a masterpage.
So for example I have two pages - default.aspx and information.aspx. Both these web forms have label controls (lblDefault and lblInfo respectively). This information is stored in a database along with the content that the label controls should be populated with. Instead of having to program a method to retrieve the content text from the database for the relevent controls on these two pages would it be possible to find the controls in the masterpage codebehind file - something like Page.Form.FindControl("lblDefault")? So for each webform using a masterpage a check is done to see if any of the controls should be populated with content from the database.
I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.
I want to open a aspx page in new window.
I am openning a web page using JavaScript open .
StringBuilder cstext3 = new StringBuilder();
cstext3.Append("<script type=text/javascript> function OpenPreviewPage() {");
cstext3.Append("open('Preview.aspx');");
cstext3.Append("} </script>");
And executing following at button click on .cs page
protected void btnPreview_Click(object sender, ImageClickEventArgs e)
{
/*This will call the OpenPreviewPage method of java script from .cs file */
string javaScript =
"<script language=JavaScript>
" +
"OpenPreviewPage();
" +
"</script>";
RegisterStartupScript("ShowPreviewPage", javaScript);
}
The problem is the PreviousPage tag in preview page is null.
repPFareDetail = PreviousPage.FindControl("repFareDetail") as Repeater;
Is there any other way to open the aspx in new window by retaining the PreviousPage.FindControl method.
How can i use findControl and how can i get id's according to FindControl method? i need to get all TextBox data there are 40 textbox. And TextBoxid data... i reall want to learn also linq method ;)

In default.aspx, there is a label as "lblBar".In one user control, I added a code below:
Dim lblBar_Local As Label = CType(Me.Page.FindControl("lblBar"), Label)
lblBar_Local.text="Test"
But lblBar never display "Test".What is wrong with my code?
Why MasterPage doesn't have Page_PreInit?
View 2 RepliesHow can do I that? Does anyone have a solution. It is also looking tricky but I don't have an answer.
View 2 RepliesI use the following method to find a control on an asp.net page recursively:
/// <summary>
/// Searches recursively for a server control with the specified id parameter.
/// </summary>[code]...
I hit a problem because it was returning the wrong control. I tracked the problem down to the standard FindControl method, and fixed it by checking that the id of the control returned did actually match the one requested like this:
foundControl = start.FindControl(id);
if (foundControl != null && foundControl.ID == id)
return foundControl;
My question is why does start.FindControl(id) ever return a control that does not match the id requested?
Consider the following code, adding 2 textboxes with the same ID (oops):
protected void Page_Load(object sender, EventArgs e)
{
string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
if (p.FindControl(TextBoxName) == null) // <-------*******
{
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
p.Controls.Add(t2);
}
Page.Form.Controls.Add(p);
}
The code is designed to stop adding the same ID twice. However, the Panel.FindControl() method is not finding a control that was added in the previous line of code.
Am I using this in the wrong way?
I mean - sure - I could manually iterate through the controls in the next level, like:
string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
bool duplicateFound = false;
foreach( Control c in p.Controls )
{
if(c.ID == TextBoxName)
{
duplicateFound = true;
break;
}
}
if( duplicateFound )
{
t2.ID = TextBoxName + "__0";
p.Controls.Add(t2);
}
But I don't understand why this isn't working, whereas Placeholder controls and UserControls work fine.
The reason I am using Panels is for CSS styling. body > div > input - but still - it isn't working.

On any page that uses this masterpage, whether it is in a subfolder or directly at root level with the masterpage, these links don't work in any browser I have except for IE (Firefox, Chrome, Opera, and Safari). By that, I mean:
1. When I mouse over them, the cursor doesn't change to a hand.
2. When I click, nothing happens visually.
3. When I click, nothing happens in code. i.e., I set a breakpoint on the click events for the buttons, and they don't get hit.
In IE, everything works as it should.
In addition, I have subnavigation on some of my child pages, implemented the same way, and it works for all browsers.
