AJAX :: Make All DropDownExtender Visible?
Aug 31, 2010I use DropDownExtenders everywhere in my project, but it bothers me that it's not visible all the time. It looks like an usual TextBox :-(

View 4 RepliesI'd like to be able to have the .NET AJAX CalendarExtender show on Load without having to click in a TextBox. If I can simulate a TextBox being clicked so the CalendarExtender will show I'll take that too.
View 1 RepliesI have a tab container with two tabs. In one of the tab panels, I have a button. I want by pressing the button to make a label in master page visible:

The event fires, the event handler is executed, but the lable doesn't become visible. If I place the button outside of the tab container, it works.
Getting familiar with ajax tabs...watched Joe's video. Am building simple wizard with first tab visible, others invisible until "next" is clicked. I know I need an onclientclick event but am very elementary with Javascript and .Net doesn't prompt javascript.

Using a modalpopupextender a panel having controls is poped-up as a modalpopup. The problem I am facing is how to make the Ajax Calendar always visible on the modalpopup.
Functionality of controls on modal popup:
1. A calendar (use of Calendarextendar preferred) and a ListBox placed side by side.
2. calendar's behavior need to be exactly the same as that acheived using a Ajax Calendarextendar
3. The Calendar is always visible.
4. The days selected by user are appended to the ListBox (with no repeatition)
Are there some existing examples of making a DIV or panel visible or not visible based on an ajax event?
View 2 RepliesI have 2 updatepanel UpdatePanel1 and UpdatePanel2. Intialy updatepanel2 is invisible. In updatepanel1 there is a dropdown list, whose Selected Index Method change makes UpdatePanel2 visible.The code
UpdatePanel2.visible =true;
seems to run without any error, but updatepanel2 is not visible on the page. Is there anyway to make it work.
This 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 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:
<br/>

<asp:DropDownExtender DropArrowBackColor="White"
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?
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.
