AJAX :: Dropdownextender Hidden By Other Control?
Jan 28, 2010
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?

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.

My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?
Mark up:
<asp:TabContainer ID="tcAuditMain" runat="server"
Visible="true" ActiveTabIndex="10" EnableViewState="true"
CssClass="NewsTab" Width="100%">
Rendered:
<div id="ctl00_ContentPlaceHolder1_tcAuditMain" class="NewsTab" style="width:100%;visibility:hidden;">

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

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....

I downloaded and installed AJAX Control Toolkit, following this link
http://www.asp.net/ajaxlibrary/act.ashx.
The tab doesn't show on the Toolbox. I right clicked at the Toolbox and select Show All. The tab and the controls shows up but all controls are gray out, look like disable. How can I make enable?

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.

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?

I have the AsyncFileUpload control within a <asp:Panel> control that I toggle visibility True/False.
For Example when the page loads pnlEdit.visible = False. Then when a user clicks on a detail record in a grid I display the panel with the AsyncFileControl ie: pnlEdit.Visible = True.
Because the the AsyncFileUpload Control is not displayed on the page right away it errors when you try to upload a file. Would anyone know how I could preload the control or configure 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.
[Code]....
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 a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

I am having some problems with my DIV, it wont display over a a DIV that has a web user control in it. Below you can find my css. I believe I have done everything right and am hoping that someone can maybe see an error that I have made and help me out. If you need any other code let me know. I also wonder if its just IE rendering it wrong?

}
The Activity DIV (same the div above just changed position)

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.
