View 9 RepliesI 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.

I have used a ajax control toolkit slide shox extender to display a slide show of images.
Currently, when a user hovers mouse over the slide show, the slide keeps on changing. I want that the slide should not change, if a user hovers the mouse.
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 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....

I 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?

View 1 RepliesI am showing some information on mouse hovering on the links. I am doing this by making an AJAX call on mouse hover the the links and fetching the data from database.
Problem is that if I mouse hover several times on the same link it will make the AJAX call and hit the database in each time. But I want if it once fetch the data from the database for a specific link on second time mouse hover it should not hit the database again. For this I need to store the data in client side some where and reuse it(I think).
What is the best approach to handle this situation?
P.S: I am having more than 20 such links in the page.
