AJAX :: MasterPage - ContentPlaceHold And UpdatePanel Cannot Work Together?
Jul 29, 2010
I have Master Page with 2 ContentPlaceHolds , called "left" and "right"
[Code]....
I have a page override 2 ContentPlaceHolds of Master Page
In this page, i have 2 WebUserControls called WUCLeft is put into "left" and WUCRight put into "right"
[Code]....
WUCLeft has a button to load WUCRight into "right" ContentPlaceHold
[Code]....
[Code]....
WUCRight has one TextBox, one Button and one Label, when I click Button, the text of TextBox is assigned to Label
[Code]....
[Code]....
The problem occurs after I press Button on "left" ContentPlaceHold to load WUCRight.
In the first, I click on Button on "right" ContentPlaceHold, nothing happens (the Text of TextBox is not assigned to Label). In the second, i click on Button, page is submitted and all control in "right" ContentPlaceHole are cleared.
What did i do something wrong?

In my webpage I have an updatepanel and a button that updates the Label.[Code]....
[Code]....
If the button is inside updapanel, nothing happens when I click the button (Label is not displayed), but if I move button outside the panel it works. (Button must be inside updatepanel and ofcourse no PostBackTrigger)

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. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.
Here's the code (.aspx) [Code]....

firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage

i have a Masterpage with a Header, a Footer and a Main Placeholder.
In the Main-Content-Placeholder i use an Update-Panel.
A Problem occurs when i make some Ajax-Action (like updating a textbox) inside the Update-Panel:
The Ajax-Behavior is OK but the footer in the Masterpage is not rendered anymore.
For Testing purposes i put the Footer Elements in the Header of the Masterpage. Then the elements were rendered.

I have a DateTime in my MasterPage.aspx that is outside of UpdatePanel1. There are two Hyperlink controls inside UpadatePanel1 to navigate or to move to the other pages. Full code of MasterPage.aspx is below.
[Code]....
If the user clicks Hyperlink to navigate or move to the other page, the DateTime will change. It means that my MasterPage.aspx render the whole page when the user clicks Hyperlink. I do not want this behavior. I want my MasterPage.aspx only render the ContentPage and the
Hyperlink inside UpadtePanel1. Controls outside UpadtePanel1 like DateTime should not be rendered again. Please advise the code to achieve my example goal.

I have read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.

I have two sliderextenders in a page, and one of them is in an UpdatePanel.When I slide the first one it set the minimum value and the number of steps of the second one (in the control panel) and it seems to work well.But if I slide the second one, as soon as I release the mouse button, my two sliders don't work anymore. I have to click them to change the value but can't slide them.

I am trying to add validation on my form. I am using AJAX controls in my form fields.
When I remove the Update panel and AJAX control, my validation starts working, but when keeping both the things together, my validation is not working. How could I make them work together?
<script type="text/javascript">
function Validate() {
var QuestionTextArea = document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion");
varError = "";
if (!IsTextBoxEmpty(QuestionTextArea, "
Question Text Area not be Empty.")) {
alert(varError);
document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion").focus();
return false;
} return true;
}
</script>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:TextBox ID="txtQuestion" runat="server" MaxLength="1000" Columns="50" Rows="5" Style="width: 380px;
float: none" Text='<%# Bind("Description") %>' TextMode="MultiLine" />
<AjaxControl:TextBoxWatermarkExtender runat="server" TargetControlID="txtQuestion"
WatermarkCssClass="water" WatermarkText="Type your Question Here.">
</AjaxControl:TextBoxWatermarkExtender>
</ContentTemplate>
</asp:UpdatePanel>
When I removes ajax extender and Update Panel. My textbox gets validated and when using UpdatePanel. No javascript function created by me is called.

In HTML I usually use the techniqe to check for different statments by calling public Strings and like in this case if test == "notTrue" wich it is not, then the following code in the if statment wont render in the HTML.
It have worked out fine but it does not seem to work for the update panel that I declare. I get this error. I wonder why that is happening and if there is a way to to this in HTML like I do here ?
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'UpdatePanel1'. If it is being updated dynamically then it must be inside another UpdatePanel.

I have some problem with the AutoCompleteExtender when it's include in an UpdatePanel.
Scenario:
I have create a UserControl with TextBox, AutoCompleteExtender and a "Save" LinkButton and I put this Control in the InsertItemTemplate of a ListView.
The AutoComplete uses a Method that I have created in a webservice.
All works fine untill i place my ListView in an UpdatePanel.
The webmethod don't fired. The strange thing is that if i put the same Control also out of my ListView it seems to work, but i can't catch the linkbutton click.

I use a tabcontrol with 2 tabs. In the second tabpanel as seen in the code I use a Fileuploadcontrol to upload Images from a users computer.
The problem is that I need to surround the tabcontrol with an updatepanel as I dont want a fullpage postback when switching between these 2 tabpanels. In this code I have the tabcontrol inside an updatepanel but the problem is that the Fileupload controls does not seem to work inside an updatepanel.
How will I solve this problem as I dont want a fullpage postback when switching between the tabs ?

I have a GridView in an UpdatePanel and in the code behind I bind to a Datatable and call the GridView's Sort method:
gvUsers.DataSource = dt;
gvUsers.DataBind();
gvUsers.Sort("DateOfBirth", SortDirection.Descending);
However, this doesn't sort the records. I have the Sort event as an asynch trigger for the grid.

I'm just getting into AJAX (little late I know) and am walking through some of the tutorials on the ASP.NET/AJAX site. One thing I've noticed is that I cannot get the UpdatePanel to work (meaning, prevent a full postback of the page) in the ASP.NET Web Site template. I can use the EXACT same markup, code, and web.config in the AJAX 1.0-Enabled ASP.NET 2.0 template and everything works as expected.

I'm using the technique described on this link to make all TextBoxes on the site highlighted when focused. Basically, in the Page_Load event of the MasterPage I set the onFocus and onBlur attributes for every TextBox found on the current page:
[Code]....
Everything worked fine until I decided to add the UpdatePanel on one page which is used for frequent data entry. Now, when the page loads initially everything is ok, but after the first asynchronus postback is made, controls inside the UpdatePanel seem to loose their onBlur and onFocus efects (controls outside the UpdatePanel are still working fine). I'm not in the best "relations" with AJAX and javascript :)
