is there any way for changing proporty of a component ,such as imagesrc of an image item , from another page?

I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?
View 7 RepliesI have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
I was wondering whether in ASP.NET it is possible to change properties of bunch of controls in one operation. Of course there are probably many ways around this, but does anybody know an elegant solution to this?
Example pseudo-code
First Name
<asp:TextBox runat="server" ID="tbxFirstName" ControlGroup="Editable" />
<asp:Label runat="server" ID="lblFirstName" ControlGroup="ReadOnly" />
Last Name
<asp:TextBox runat="server" ID="tbxLastName" ControlGroup="Editable" />
<asp:Label runat="server" ID="lblLastName" ControlGroup="ReadOnly" />
protected void ChageMode(bool isReadOnly)
{
ControlGroups["Editable"].ForEach(c => c.Visible = !isReadOnly);
ControlGroups["ReadOnly"].ForEach(c => c.Visible = isReadOnly);
}
On my .aspx page i want to be able to show and hide certain panels depending on user selections (radiobuttonlists).
For example in my aspx page i have;

But when I try to run the code I get;
"Object reference not set to an instance of an object" on this line If RadioButtonList1.SelectedItem.Equals(3) Then
So what I'm trying to accomplish is this

The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
Can we write property in property?IN the page load event we have page property and we can find another page property in that page property.Pls let me know how this is happening

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is

View 6 RepliesLet me set this up:I have a master page. I have a regular aspx page - this page contains a Menu and a User Control.When I click on the Menu Item, it fires my click event. This will post back. The Master Page Uses Placeholder Controls where I dynamicaly create Label Controls with information and add them to the Placeholders. These contain data with tooltips. This works great. After the Master Page and Web Page load, it will then fire the Click Event from the Menu.The problem:The Click event will update data in the database, This data may effect the values that are created on the Master Page that are placed in the Placeholder controls. I can't seem to figure out how to change that data.
What I have tried:I have created a reference to my Master Page on my Web Page. In the Click Event after I have made changes to the Database, I call the function on the master page that Creates all the data and places them in the place holders. It Runs, but nothing changes on my page.Am I going about this wrong? Is there another way of doing this? I terrible work around, would be to just reload the whole page after I do an update.

I have a ASP.NET C# 3.5 web application, where I am changing the masterpage & theme for certain pages that have ASP.NET controls. The problem is that when the masterpage/theme is changed, the ASP.NET ImageButtons on the child page cease to function altogether and show up as normal images. The html source for that page would show a disabled="disabled" field added to the ImageButtons at runtime. All other controls including ASP.NET Buttons work fine, only ImageButtons are effected. I've changed masterpages in files many times and have not come across this problem, probably because I rarely use ImageButtons. I'm beginning to think it may be a bug in .NET itself, but it could be code related. I've also executed a javascript function after
load to set the disabled field to "enabled", which has no effect on the ImageButton but the source confirms it is enabled. The MasterPages / Child Pages are relatively straight forward and I've tried many different combinations to get it working. I'm changing the masterpage & theme via a function like:
public static void ChangeMaster(System.Web.UI.Page page)
{
page.MasterPageFile = "~/GX.Master";
page.Theme = null;
}

View 4 RepliesLet's say you had a page like an eBay auction, where some of the content (top bidder, bids, history, etc) needed to be up to date but other sections would likely never change, like the description. I'd like to know the "right" method for getting that static section cached.
The "cheezy" solution would be to code it up in a separate javascript .js file as a bunch of "document.writeln()" calls, but that's plain evil and ugly.
If I made it a Content section of a master page, that might get it cached at the server, but the client has no way to know that this particular section of the page will never change.
I could IFRAME it but I don't always know the dimensions.
I'm sure this has all been done before, and as much as I love my own wheels, I'd rather not reinvent this one :-)
My Master Page has a heading with tabs. The code looks something like:
<CT:Tab ID="tabHome" runat="server" Url="/index.aspx" Text = "Home" Highlight="true" />
<CT:Tab ID="tabFun" runat="server" Url="/fun.html" Text = "Fun"/>
<CT:Tab ID="tabBlog" runat="server" Url="/blog" Text = "Blog"/>
I can think of two ways to control which tab is highlighted from within a user control:Have the user control implement an interface. The master page can decide which tab to highlight based on which interface is implemented, or based on a method in the interface that returns a string.In the Page_Load (or Page_Init) function, tell the master page (via FindControl or via a function in the Master Page) which control to highlight.I don't really like either of these solutions. Is there a clean way I could control which tab is highlighted from the control at design time (i.e., in the aspx file)?

I've a gridview control that has paging enabled. The control works completely fine in IE. However I was shocked to learn that the same page is not working on firefox i.e when I click on a page index the grid doesn't show selected page's data!
The page is posted back when I click a page index, I've checked it in debug mode as well. However the code for "Page Index Changing" is never fired!
