Catch SelectedIndexChanged Event Of Accordion Control In AjaxToolkit
Oct 20, 2010
I have an Accordion control that is populated dynamically. I want to catch the event raised when a new pane is clicked on to open. I don't see the event at all in intelli-sense and when I code it by hand anyways I get errors. Is there any way to catch this event? The goal is to let a control in the masterpage that is holding the Accordion know when the Accordion has changed so it can update another control.

I am creating a nested accordion in the code behind which is populated from my data table. The requirenment is
1. Main Accordin - create department Panes
2. sub accordin - Each department pane has a accordin in the contnet are.
3. sub accordin panes - people from that department show up as panes in sub accordin.
I was able to impelment this model but the problem is that the sub accordin ( with people) would not slide. First one is opened by default and i see hand on the other header panes but they dont slide (up and down). They do have a content though. P.S - if i implement the same nested according in aspx it works fine. My code
[Code]....
Update - I found that I get "Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element" javascript error when i try to create the nested accordin.

I have one dropdownlist control which populates values to other controls. Means upon selecting item in dropdownlist, related data is populated in other controls. I have also assigned dropdownlist's autopostback to TRUE. Everything is working good as far as dropdown has more than one item.
Whenever there is only one item, selectedindexchanged event is not fired (obviously.....) and eventually the data is not populated to other controls.
How could I get rid of this scenario? I mean which event should I use to avoid this?
At this time, I have just added the first item as something like "---Select Item---" , so when end-user has to select different item and thus the selecteditemindexchanged is fired. no biggie... but just wondering if proper solution is available....

This is how i have it setup:DAL: a dbml file for the contextBLL: All my BL rulesTypes: I made type for every object that i return to my presentation layer.Now that i made types and use this structure i find it hard to understand how to manipulate data. Normally i could just bind my datacontext to a grid and just activate all the datagrid's possibilities without having to worry about anything. for example when i want to enable sorting, i have to write my own logic to return teh right rows to the grid etc.
I have a multiview with two datagrids. The first datagrid is an overview grid and has an option to select an entry. When i select the entry i switch to my second view and I want to show the details for the selected object there.However... I bound a List to the first grid and now I don't know how to find out what entry is selected. I have an event handler for the SelectedIndexChanged.

I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :
[Code]....
[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...

Basics: I have a text box (txtDepositAmount) that people can enter a deposit amount into and a drop down (ddlSelectedTerm) that sets the terms. Through these two values I calculate the APY (lblCurrentApy).
Rules: If only one of the values is selected I still want to do an update on the current APY label and clear it. If either value changes I want to update the current APY and recalculate.
The problem: As soon as I click away from the textbox and onto the drop down to select my term the drop down flashes and closes because the textbox TextChanged event was just fired.
I have to click on the drop down a second time to be able to select anything!
Do I need to change what event I'm looking at or do I need to move some of the controls outside of the UpdatePanel? Can this only happen if some of the business rules change? Should I just give up and go to javascript?

I have a property call (add user to a group) that would be hard to write code to check if user is already in group and I need to call it multiple times sometimes for the same group. anyhow it throws an error if user is already in group. easy way if to just put in a try catch and do nothing for the catch. it works fine except there are several errors in the application event log for this error when it happens. I would rather it not to log this error as it takes up time when looking in the event log to say - this is not a valid error log. so is there a way to tell a try catch to not log in the event log an error it is catching? I would rather not change any settings for the whole site but perhaps just this 1 page might be acceptable.

I have a DropDown which is bounded to an ObjectDataSource. On its data bound event, I am adding "--select--" value on the 0 index. I have a LinkButton on the page and on its client click, i am selecting different item on drop down (using JavaScript). Suppose there are 3 items like --select--, option1, option2 and option3 and now on link button's client click i selected option3, now if I select the default value "--select--", it does not fire the SelectedIndexChanged event. If I select any other value then it fires. Why does it not work for the default value?

My application allows a team captain to enter the results of an 8-ball game then submit those results. In doing so the captain is brought to the next page to enter the results of the 9-ball game. But, there are games every week so there is a dropdownlist on both of the forms allowing the captain to select which date he/she is entering the information for. There are 14 weeks with the date displaying as the text value.
After the user selects the appropriate date and enters the results of the 8-ball game he is brought to the next form but he has to select the date again. Both forms ddl selectedindexchanged event enacts a whole lot of code which is required to allow the processing of the data.
I can capture the selected value from the first form and get it to the next form for 9-ball and even set the selectedvalue correctly, but that doesn't trigger the selectedindexchanged event. I want to put some code in the pageload to pass the selectedvalue to the selectedindexchanged event and trigger it to run with that value.
Is this even possible? I haven't been able to google my way out of this perdicament despite many hours of effort. And I know that users are going to spend 20 minutes entering all the data before realizing that they forgot to select the correct date in the ddl. What to do?

I have an empty GridView object on a page that I bind to a LINQ qry result at run time. The GridView has a 'Select" button that fires the SelectedIndexChanged event and it's inside of this event that I'd like to access the data of one of the fields in the selected row.So far, I can only find one way to do this, and it seems suboptimal:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView2.SelectedRow;
string UserID = row.Cells[1].Text;
//Do stuff with the userID
}
So this just access the cell data directly based on the cell index. The UserID just happens to be in the second cell and so it works. But later down the road, the UserID may not be in that same column.
