Forms Data Controls :: On Dynamic Control The DropDownList SelectedIndexChanged Event Fires Several Times?

Aug 4, 2010

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...

Web Development - SelectedIndexChanged For Programmatically Created Dropdownlist In ASP.NET Fires Multiple Times.

Mar 12, 2010

Consider the following:The SomeEvent fires as expected when any of the dropdown's selection is changed. However if say DropdownList2 has a selection made then I make a selection with either DropDownList1 or DropdownList3, then SomeEvent fires again. What is causing this behavior and how do I get just a single raising of that event?I suspect that when the viewstate for the dynamcially created dropdownlists is restored and the selection restored, then the event is fired because technically the selected index did change when the control was recreated. The reason I suspect this is that the event fires the for each dropdownlist.

Forms Data Controls :: DropDownList -- SelectedIndexChanged Fires Every Postback Whether Changed Or Not?

May 12, 2010

<asp:DropDownList ID="cboItemsPerPage" runat="server" CssClass="standardComboBox" AutoPostBack="true" EnableViewState="true" OnSelectedIndexChanged="cboItemsPerPage_SelectedIndexChanged">
<asp:ListItem Value="1" Text="1" />

[URL]Initially if I make a selection it will automatically post back and firecboItemsPerPage_SelectedIndexChanged. If I then post back by clicking one of the other buttons on the page, cboItemsPerPage_SelectedIndexChanged will continue to fire, despite the fact that the value has not been changed.I want it to be postback only when selected index is changed, not in every postback

Web Forms :: Dropdownlist Control SelectedIndexChanged Event?

Jun 22, 2010

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....

Web Forms :: On-Click Event Fires First Time But Not Subsequent Times?

Aug 2, 2010

I have a LinkButton which fires an OnClick event to update some Labels; however, after the first firing of OnClick, it won't fire again when I click another (or the same) LinkButton which runs the same OnClick event. (It's a list of people, each a LinkButton, and clicking on one brings up their details)

If I leave the page a few minutes, it will work again, almost as if whatever was preventing OnClick firing timed-out. Of course, this won't be any use to the users!

This is my ASP.NET code for the LinkButtons (encapsulated in a DataList):

[Code]....

All the connections work, the data is retrieved, etc, so everything except the OnClick firing works. I've done a search of the internet and the forum, and found this seems to have been a long-standing problem since the first ASP.NET, but there is no solution for ASP.NET 3.5. Does anyone know what causes this, or where I might be going wrong?

Forms Data Controls :: Fire SelectedIndexChanged Event Of DropDownList When SelectedValue Is Coming From Database Table?

Jun 28, 2010

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

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.

Forms Data Controls :: ListView Select Button Does Nothing And SelectedIndexChanged Never Fires

Jun 19, 2010

I have a listveiw populated from a List<> in the code behind using the following code:

SubId = Convert.ToInt32(Request.QueryString.Get("SubId"));
using (JodyCoryDataContext myDataContext = new JodyCoryDataContext())
{
var SelectedRings = from jewlery in myDataContext.Jewleries

[Code]....

The page displays the images from the list<> and button ok but nothing happens when i click it other than postback. Furthermore even when i set up a test button wich changes the ListView.selectedindex the ListView.SelectedIndexChanged event never fires even though i can read the selected index and see that it has changed.

I'm guessing that it's something to do with using a list<> from the code behind to populate the listview but i must confess to being completely clueless.

C# - OnCheckedChanged Event Fires More And More Times For Every Time It Is Clicked?

Aug 31, 2010

I have an ASP.NET page that contains a gridview.

I have to create columns dynamically based on a datatable, some field type info and some header texts.

I do that by creating templates.

It created the grid fine and all looks good, however when i click a checkbox and the checkedchanged event fires then something odd happens

The first time i click its fine and i get the expected values in the event

But the second time then the event gets fired with the values from the first time and then again with the values from the checkbox that i actually clicked.. The third time the event gets fired 3 times, first 2 times with the old values and the third with the correct value.

Here is the code:

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Text.RegularExpressions;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;........
