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 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?

I have a web application build on asp.net, the Textbox onchange event not working in chrome? On page load i wrote this code,
textbox1.Attributes.Add("onchange", "SetEditDataFlag();");
SetEditDataFlag() -- it is a javascript function. When I browse the application in chrome then this function is not called when i changed some value on the textbox.Its working properly in IE.

I have some code which fires when user selects an item in dropdownlist. Now i want the same code to fire when i set selectedindex programmatically.
I have tried setting
ddlSystemLevelDCP.SelectedIndex=2;
and this as well
ddlSystemLevelDCP.SelectedValue="2";
None of them fires this event.However when user changes the selection,this event fires.Please tell me what am i missing.

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?

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)

My text box change event.

My page load Code: Note: PageUniqueIdr = PageUniqueId retrieved from the QueryString.

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 my ReorderList setup, and it seems to work. It doesn't give me any errors, and it allows drag/drop of the entries.
BUT, it never updates my datasource. I have tried putting breakpoints on the update events, both on the reorder list, but also on the datasource, none fires.
What could i possibly do wrong, to achieve this?
Here's my code, just in case:

I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!

I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.
