So 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....

when selecting an item from any of the dropdown controls the hover menu disappears:

I am having a problem with my menu. My navigation menu gets created with data from different tables in a database. When the page loads after a few minutes the navigation menu disappears from page. Does anyone have had this problem or knows how to fix it?
View 3 RepliesI am using ASP: menu in my site.master page ' but when I clicked on any button or drop down from other page the menu is disappeared. Why my menu is disappearing from the site.master page ?
My code is :
<asp:Menu ID="MainMenu" runat="server" Orientation ="Horizontal" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" >
<Items >
<asp:MenuItem Text ="Home" NavigateUrl="AllEMP.aspx" >
</asp:MenuItem>
<asp:MenuItem Text ="Menu" NavigateUrl ="~/Default.aspx">
</asp:MenuItem>
</asp:MenuItem>
</Items>
</asp:Menu>
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 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 RepliesCurrently, 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"
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.

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. The code works fine however int VS 2008 Debug mode, its throwing the exception:Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.If I click ignore or continue, the taret label is properly populated with the appropriate value. Has anybody encountered this and is

View 4 RepliesI have an asp:UpdatePanel in my .aspx page.Within the panel I have placed an infragistics ultrawebgrid control.Upon clicking a button (placed outside the panel) , I have to export the data in the grid to excel.I am using
UltraWebGridExcelExporter(Infragistics object) for this. The export will occur only with full postback.For this I have added a PostBack tigger for the button to the update panel.But once the export is complete, if I change the selected item in a dropdownlist(Autopostback="true") in the same page,the updatepanel gets invisible.

we are testing the Razor webgrid with Ajax. Works absolutely fine in IE8 when sorting in paging. However in IE7, any attempt to sort or page causes the grid to vanish from the page, leaving a blank space. The HTML that should be there, isn't!Has anyone come across this issue? How could we debug it? Page code below:
