I need to perform actions (e.g. hide panels) when clicking on the dropdownextender arrow - before the dropdown panel is being displayed.
How should I perform this? should I use onclientpopulated?
I am getting an exception that child actions are not allowed to perform redirect actions. Although I can understand that this might is true in most situations I do believe that the framework might allow this to pass when a Child Action is calling another child action like in this example:
I have this code in my CountryController (I compacted it a bit but the main concept remains that I have a controller with Child Actions only):
[Code]....
This exception is being thrown:
Server Error in '/' Application.
Child actions are not allowed to perform redirect actions. Description:An unhandled exception occurred during the execution of the current web request. Review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Child actions are not allowed to perform redirect actions.
I'm trying to built a website which performs actions (for example, perform backup or sends email or process data) on a specific time like every Friday 12 PM. Is there any tricks I can do with ASP.NET using C#?
View 2 RepliesThis is what I see when I click on arrow which is an image in DropArrowImageUrl - UI is weird. Changing image does not help. I am sure that it should be a common problem. Code is very simple:
<asp:Image ID="_targetImage" runat="server" ImageUrl="../Images/Actions.png" />
<ajaxToolkit:DropDownExtender ID="_dropDownExtender" runat="server" DynamicServicePath=""
Enabled="True" DropDownControlID="_panelItems" DropArrowImageUrl="../Images/DropArrow.png"
TargetControlID="_targetImage">
</ajaxToolkit:DropDownExtender>
I use DropDownExtenders everywhere in my project, but it bothers me that it's not visible all the time. It looks like an usual TextBox :-(
<script
type="text/javascript">
I have a label with a dropdownextender, and below it I have a gridview. When it drops down, it should go on top the gridview , but instead half of it is hidden because it goes behind the gridview. how can that be taken care of?
View 5 RepliesSo I got 2 updatepanels on my page. In one there is a Timer which updates for example a label. In the other one there is a dropdownextender. Everytime the timer ticks while the dropdown menu is displayed the menu disapears. I attached the sample code below....any insights on this? And yes, the dropdown and the label need to be in two seperate updatepanels....

Currently, when you click mouse on a control, you see all options. However, I need to be able to see all options when mouse is just over the control.
View 9 RepliesI would like to Post back an update panel after the drop down is hidden.
I found some javascript that will keep the panel open wile the user interacts with the CheckBoxList i have inside. Currently I am updating the panel when the function stops blocking the closing event. This is not firing every time. So i am wondering if there is a java script event i can catch to fire the post back after the drop down is hidden and if someone can provide a simple example of doing so. The code inside the event i got covered, binding to the event is ware i am lacking.

in my aspx page i have this code:

<asp:DropDownExtender DropArrowBackColor="White"
Using cascading dropdown extender we have to define web method. In that web method does the parameters that we declare should match names like "knownCategoryValues","category" etc ? Suppose if we write "knownCategoryValues1" insteed of "knownCategoryValues" then why my webmethod is not called ?
And if i give "knownCategoryValues" then it is called ?For the First time i have seen parameters name matters in Method parameters list. But why in this case different naming causes problem ?
I am using the following code:
<ajaxToolkit:DropDownExtender ID="TextBox1_DropDownExtender" runat="server" DynamicServicePath=""
Enabled="True" DropDownControlID="panelItems" DropArrowImageUrl="~/Images/DropArrow.png"
DropArrowWidth='26' TargetControlID="Image1">
</ajaxToolkit:DropDownExtender>
However, it does not set the width of DropArrowImage correctly.
I found the following post http://ajaxcontroltoolkit.codeplex.com/workitem/24194 but I am not sure of where to find DropDownBehavior.js to implement proposed solution.
Is it possble somehow to set the widht of DropArrow?
the dropdownextender works fine until I scroll down the page, see the following screenshots.
View 2 RepliesI have the code below to implement a dropdownlist with checkboxes. My problem is that every time i click a checkbox the dropdownlist closes and i need to reopen it to select more checkboxes. How do i make it so the dropdownlist dosn't close until i click off of it?

I am trying to keep the drop down open till mouse out.
I have found a hand full of sample scripts that are all trying to do this. I did manage to keep the drop down open while the user clicks on the check boxes.

I would like to instead of just removing the event handler also trigger the "close" event for the drop down list on mouse out. Not the JS expert so i dont know ware to start.

The following code listed on the bottom is a dropdown extender contained with a listview insert template.

I have Page_A.aspx and Page_B.aspx
Page_A.aspx has a text box and a Send button.
Page_B.aspx has a Label control on it, inside an UpdatePanel
I want that when I type something in Page_A.aspx and click Send, the text of Label on Page_B.aspx should be updated with the text box text and the UpdatePanel should be updated. Is this possible?

I am trying to integrate ASP .Net AJAX into an existing application, but so far I am striking out.After significant digging, I found that for some reason, the ScriptManager was set so that SupportsPartialRendering is false, overriding EnablePartialRendering. From looking at the MSDN documentation, it seems to me that this should not be the case.The rules for determiningrSupportsPartialRendering are (from MSDN):The W3CDomVersion property value must be greater than or equal to 1.0.The EcmaScriptVersion property value must be greater than or equal to 1.0.The SupportsCallback property value must be set totrue.Using Firefox 3.6 and IE7+, these tests should have passed. W3CDomVersion = 1.0, EcmaScriptVersion=1.4, and SupportsCallback=true.n an effort to see if I could get around it by setting the value myself, I overrode the OnInit function in the code behind to explicitly set SupportsPartialRendering to true.his appeared to attempt to start an async postback, but failed with the javascript error "this._postBackSettings.async' is null or not an object" from within the ASP.Net AJAX scripts.
Also, I created a sample application outside of my existing project and got it working exactly as I wanted. When I copied and pasted all the code from the sample project and put it into the existing solution (aspx and code behind) it experienced the same issue. I know that it has something to do with the existing solution, but I am at the end of my rope as to what it could be.Other relevant information:he solution I am trying to integrate this into was at one time upgraded from ASP .Net 2.0 to 3.5.The controls which trigger the async postback are in a repeater and are being registered with ScriptManager.RegisterAsyncPostBackControl during prerender by looping over the bound items in the repeater. This occurs after the Repeater is databound. At the same time, triggers are dynamically added to the UpdatePanel. Code snippet (taken from OnPreRender):
[Code]....
I think the "_postBackSettings.async is null" error is something of a red-herring and is an indication that I am headed down a wormhole, so I am not considering heading down the path of forcing SupportsPartialRendering to true for now. Does anyone know what else could be turning it off in the first place? Or what else could be preventing partial rendering from functioning as expected?
For example : I have UserID and UserName. So I use DropDownList. UserName is DataTextField and UserID is DataValueField. So User can choose their name and I save UserID to my database. But If User is new and not registered. I want to allow to type in DropDownList and I save the name to database. So for registered people can choose and not registered people can key in.
View 2 RepliesHow can you perform page navigation with Jquery tabs without the ajax events firing? Following the tutorial, I added
$("#tabs").tabs({
select: function (event, ui) {
var url = $.data(ui.tab, 'load.tabs');
if (url) {
location.href = url;
return false;
}
return true;
}
});
And I added hrefs to the tabs going to other pages. The problem is, I have ajax used on the page and onload it posts to the url with an ajax call. I was hoping to disable ajax altogether for the tabs and just use them for straight navigation so I can leverage the styles.
Is it possible to perform a file upload within an update panel.
