Web Forms :: UserControl Value Is Not Changed When Written Through Code Behind?
May 3, 2010
i have one user control which has hiddenField name ='hdnShow' as runat='server'
my scenario is that i have a function in userControl name Show(MessageType);
void Show(MessageType msg)
{
switch(msg)
{
case MessageType.Success:hdnShow.Value= "Success fully saved";
[Code]....
when i execute it and tries to get value of hiddenField thru javascript it still predicts the initial value.
Strange thing is that when i make a textbox in webusercontrol and then try to set its value thru this function.
even the textbox value don't change we can see it on aspx page that value is still the initial one.
some site has asserted that we can do that thru preRender event but it is not working.
may be it is happening coz it is in updatePanel??
yeah i have tried EnableViewstate true and false both condition.

After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.

I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5
To
http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3
To
http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs

I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?

I have a page that shows the value of a property of my model. The value of that property is changed in the action-method of the controller (that recieves the model as a parameter). It turns out that this line of code:
<%= Html.TextBoxFor(m => m.Problem)%>
does not represent the value that it got in the action-method-code (just the value it got from the POST), but this does:
<input type="text" value="<%= string.IsNullOrEmpty(Model.Problem) ? "" : Html.Encode(Model.Problem) %>" />
Is this a bug or is some caching-mechanism working against me?
BTW, it is especially annoying when using HIDDENs, because the user can never change that value at all... That's how I found out...
I have a demo-project demonstrating the problem here for download. It is based on the default-application, so very small.

I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value
why is the value null on the content page?

In a form control i have a listview and some textboxes and comboboxes.
When a list item is selected i add the data to the textboxes so the user can change them. non of it is databound. all the changes are made in the code.
I wanted to know the best way to find out if i the checkbox_SelectedIndexChanged event was triggered by the code behind or the user. is this possible through either the sender object or EventArgs. i didnt want to have to set bool values or something like that every time i change the values from the code. prefer a solution where i only have to add code to the checkbox_SelectedIndexChanged() method.
NB: the initial use for this is just to enable a save and cancel button (without having to remeber and compare values). There will be other uses for this later on as well.

In ASP .NET 2.0, I've created a user control which is meant to work as a dropdown or popup by using an <input type="button" id="btnTogglePopup" runat="server" style="display:inline"... /> and <div id="divPopup" runat="server" style="display:none" ... /> the rest of the controls are contained inside this div, and they do mantain their values between posts, etc. This button 'runs at server' but it's not intended to post back or submit.It just toggles the popup (div) visible/hidden using Javascript client code by setting the div's style display property to "none" or "block" The problem I'm having is that when a page containing this control posts back, the state visible/hidden of the div is not maintained. If the user had the popup open, after the postback, it will display closed.I've read a bunch by now about ViewState & ControlState, and have the save and load contol state methods working, but when I step thru them they load old values (setting the popup to hidden all the time),and the popup doesn't work! I've come to think that b/c when the button is clicked,the visible state of the div is changed in client code w/o a postback, maybe I have to maintain this state info in a hidden fiel or something like that?At the same time I don't want to have a hidden field if it's unnecessary,and I may just doing something wrong.

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)

There are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.

For our ASP.NET project for school we had to build a sport event management web application.
We provide the application in three languages (English, Dutch & French) which you can switch all the time. This has worked all the time for all users, well that's what we think anyway.
Yesterday I found out that switching from one to another language isn't working for 2 of our users. So I started testing a bit and I always got this error.
I'll try to explain what happens behind the doors when changing the language:
First of all the current language is saved in a session so we don't have to check the user row every time a page loads. Besides that we save the language in the users row in the database.
Users Table:
Id int
Unchecked
Email varchar(150)
Unchecked
