AJAX :: How To Fire A ModalPopupExtender On The SelectIndexChanged Event Of A Dropdownlist
Mar 17, 2010
How can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?
I only want it to fire when a particular value is chosen in the list.
I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.

I added dropdownlist & textbox control to gridviewrow dynamically on button click.I bind datatable to dropdownlist programatically & dropdownlist Datatextfield="product" & Datavaluefield="Amount". now my question is: when I select a product in dropdownlist,the corresponding product item "Amount" should display in the textbox. I write in my dropdown event like this:
protected void ddl1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow gridViewRow = (GridViewRow)(((Control)sender).NamingContainer);
DropDownList ddl1 = (DropDownList)gridViewRow.FindControl("ddl1");
TextBox itProductQuantity = (TextBox)gridViewRow.FindControl("itProductQuantity");
itProductQuantity.Text = ((DropDownList)sender).SelectedValue;
}
I call that textbox in Gridview row databound. why event is not firing?

I have the need to fire off a modal pop-up inline. I have a modal panel defined, and works when I click a test button on the page. Unfortunately I need it to work like this:
1.) A user clicks a 'Save' button
2.) In the code block for that button's Click event, there is a check for a certain constraint.
3.) If that constraint exists, I need to show the modal pop up and determine if the following code in the Click event is executed based off of the return of that modal pop up.
Easily accomplished using a Forms message box. But this is an ASP.net app. What I've tried so far is creating a button that uses a style with "display: none" and programmatically firing off that hidden button's click event. Unfortunately the code does execute but no modal pop up is displayed and the code continues to execute.

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?

Is there a way that if certain items are selected in a DropDownList to fire up a ModalPopupBox. Basically if any value except for one value is selected, I want a popup warning them, are you sure?
I have the Popup Frame, I have the Popup Extender. I just don't know how to wire the two together using the TargetControlID. I don't want the popup to just automatically come up when the dropdownlist is selected but only if its not value "X".
I figured instead of doing this in parallel, I could check it after the fact when the form is posted using the extender.show() command but my program is crashing because the targetcontrolid for my modalpopupextender is null. I don't have a targetcontrolID in that case?

like to ask how to stop triggering event Timer_Tick when ModalPopup is already shown. I use the following code:
[Code]....
I'd like after 15 seconds the ModalPopup to show, but the timer go on counting and triggering Timer1_Tick event. This operation should happen on user basis. So, if one user ModalPopup shows and stops Timer1_Tick event, for another user on the website, the Timer1_Tick should work.

I have a form which has some dropdownlists (ListItems "Yes" "No"). I use my form to Enter data & submit to database and use same form to Edit aswell. Like I redirect to this form from another page with a QueryString. If there is a QueryString then SELECT * FROM Table WHERE ID = QueryString's value & fill all the controls in the form like
[URL]
I have certain things to do when DropDownList.SelectedValue = "Yes" so I can use SelectedIndexChanged event handler & AutoPostBack="true" when submitting form for the first time. Now when I edit the information(Data filled from table as stated above). How can i automatically fire all events like DropDownlist SelectedIndexChanged in the page_Load iteslef so that all the things that are supposed to be done when DropDownList.SelectedValue = "Yes". I'm posting my test code for reference to explain what I'm trying to do. This is just the Idea. I have something else to deal with if i can get this stright. I need to dynamically add controls based on the values of DropDownList. please suggest some thing guys.

I have a form in which I have a gridview with a LinkButton culumn in which when the user clciks a modal popup extender shows up. In the modalpopup I have a dropdownlist which is filled from DB in code behind. but when the user clicks on Add button in modalpopup panel, the selected value of the dropdownliast is always its default value.
[Code]....
here is my code behind:
[Code]....
I traced my code behind, the fillData() which fills up dropDownList is called only once in page load's first time.
PS. I understood the problem exists only when the modal is poped up by linkbutton click of gridview. when It is poped up by a button outside the grid it workes fine.
