AJAX :: UpdatePanel OnSelectedIndexChanged Not Firing?
Sep 15, 2010
I have an UpdatePanel with a dropdownlist (countries) and a multi-select listbox (locations). If the user selects a country, the locations for the country get populated. By default, all locations must be selected.
Works absolutely fine, except that if you choose a country, then change the country back to the original value ("All Countries") - the OnSelectedIndexChanged doesn't fire. Page PostBack occurs, tho.
AutoPostback is true, everything else works fine, just can't get the darned event to fire on when the original value is Selected. The result is that the drop-down list gets populated with the default list of locations (for All Countries), but they aren't selected...only the subset from the previously selected country are selected?

The OnSelectedIndexChanged event is not firing for my dropdown box. All forums I have looked at told me to add the AutoPostBack="true", but that didn't change the results.

I have an updatepanel with a radiobuttonlist, which looks like this in my markup code:(also, I tried specifying the AsyncPostBackTrigger with the specific eventname "OnSelectedIndexChanged" - no succes either).
[Code]....
In code behind, loads of things happends. But the primary important thing is this method which is being called:
[Code]....
Now, in each postback this is set as a datasource (it is not loosing its datasource because of some timer).What my problem is: Even though the Page_Load event is being fired and I can see the datasource has changed, the content I see in the radiobuttonlist stays the same!

I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:

I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.

I have a problem with my Linkbutton which is not firing the RowCommand of my gridview.
Just for an Idea what I am doing is a follows:
1. WebForm
WebForm hosts UserControl_A.
2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender
Updatepanel of UserControl_A consists of multiple Panels.
Each Panel consists of a Gridview1.
Upon each Panel expand UserControl_B is loaded.
3. UserControl_B = Details View & a couple of Linkbuttons in GridView2
Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.

I have got an issue after updation in UpdatePanel. The issue is the jquery events are not working/firing after the updation in UpdatePanel. At first time, the jquery events work, but not after the updation in UpdatePanel. If I remove the UpdatePanel, the problem is solved. But I have to use the UpdatePanel.

I have a GridView that uses custom paging inside an UpdatePanel (so that the paging and sorting of the gridview don't cause postback). The sorting works fine, but the paging doesn't. The PageIndexChanging event is never called. This is the aspx code:
<asp:UpdatePanel runat="server" ID="upSearchResults" ChildrenAsTriggers="true" UpdateMode="Always">
<ContentTemplate>
<asp:GridView ID="gvSearchResults" runat="server" AllowSorting="true" AutoGenerateColumns="false" AllowPaging="true" PageSize="10" OnDataBound="gvSearchResults_DataBound"
OnRowDataBound ="gvSearchResults_RowDataBound" OnSorting="gvSearchResults_Sorting" OnPageIndexChanging="gvSearchResults_PageIndexChanging" Width="100%" EnableSortingAndPagingCallbacks="false">
<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:HyperLink ID="lnkAdd" runat="server">Add</asp:HyperLink>
<asp:HiddenField ID="hfPersonId" runat="server" Value='<%# Eval("Id") %>'/>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="First Name" DataField="FirstName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="FirstName" />
<asp:BoundField HeaderText="Last Name" DataField="LastName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="LastName" />
<asp:TemplateField HeaderText="Phone Number" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" >
<ItemTemplate>
<asp:Label ID="lblPhone" runat="server" Text="" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerTemplate>
<table width="100%" class="pager">
<tr>
<td>
</td>
</tr>
</table>
</PagerTemplate>
</asp:GridView>
<div class="btnContainer">
<div class="btn btn-height_small btn-style_dominant">
<asp:LinkButton ID="lbtNewRecord" runat="server" OnClick="lbtNewRecord_Click"><span>Create New Record</span></asp:LinkButton>
</div>
<div class="btn btn-height_small btn-style_subtle">
<a onclick="openParticipantModal();"><span>Cancel</span></a>
</div>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="PageIndexChanging" />
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="Sorting" />
</Triggers>
</asp:UpdatePanel>
In the code behind I have a SetPaging method that is called on the GridView OnDataBound event:
private void SetPaging(GridView gv)
{
GridViewRow row = gv.BottomPagerRow;
var place = row.Cells[0];
var first = new LinkButton();
first.CommandName = "Page";
first.CommandArgument = "First";
first.Text = "First";
first.ToolTip = "First Page";
if (place != null) place.Controls.Add(first);
var lbl = new Label();
lbl.Text = " ";
if (place != null) place.Controls.Add(lbl);
var prev = new LinkButton();
prev.CommandName = "Page";
prev.CommandArgument = "Prev";
prev.Text = "Prev";
prev.ToolTip = "Previous Page";
if (place != null) place.Controls.Add(prev);
var lbl2 = new Label();
lbl2.Text = " ";
if (place != null) place.Controls.Add(lbl2);
for (int i = 1; i <= gv.PageCount; i++)
{
var btn = new LinkButton();
btn.CommandName = "Page";
btn.CommandArgument = i.ToString();
if (i == gv.PageIndex + 1)
{
btn.BackColor = Color.Gray;
}
btn.Text = i.ToString();
btn.ToolTip = "Page " + i.ToString();
if (place != null) place.Controls.Add(btn);
var lbl3 = new Label();
lbl3.Text = " ";
if (place != null) place.Controls.Add(lbl3);
}
var next = new LinkButton();
next.CommandName = "Page";
next.CommandArgument = "Next";
next.Text = "Next";
next.ToolTip = "Next Page";
if (place != null) place.Controls.Add(next);
var lbl4 = new Label();
lbl4.Text = " ";
if (place != null) place.Controls.Add(lbl4);
var last = new LinkButton();
last.CommandName = "Page";
last.CommandArgument = "Last";
last.Text = "Last";
last.ToolTip = "Last Page";
if (place != null) place.Controls.Add(last);
var lbl5 = new Label();
lbl5.Text = " ";
if (place != null) place.Controls.Add(lbl5);
}
The paging works if I don't use custom paging, but I really need to use the custom paging. I can't figure out why the PageIndexChanging event isn't fired when I'm using the custom paging.

I have an UpdatePanel which has inside a detailsview, this DetailsView has a TemplateColumn with a UserControl.The UserControl has a NumericUpDownExtender and when the user clicks on an arrow or changes the value of the textbox a server event is raised (this is made by me, not default behaviour). I do this by using the add_currentChanged of the extender (in the javascript pageLoad function, and remove_currentChanged (in the javascript pageUnload function) and implementing the interface ICallbackEventHandler in the UserControl. My problem is that when the user click on the arrow, the event is raised twice and the correct value is overwritten.

I am creating an array of checkboxes :
1. chkresponse = new System.Web.UI.WebControls.CheckBox[cnumber + 1];
for (int
i = 0; i < cnumber + 1; i++){
chkresponse[i] = new System.Web.UI.WebControls.CheckBox();
chkresponse[i].CheckedChanged +=
new EventHandler(chkresponse_CheckedChanged);
chkresponse[i].AutoPostBack =true;
}
2. thereafter adding them to a panel
Panel1.Controls.Add(chkresponse[n]);
3. then added the checkedchanged event:
public
void chkresponse_CheckedChanged(Object sender, System.EventArgs e)
{Label1.Text = "response";}
but the event is never fired. the panel is insdie an updatepanel.

I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>
Here is the Page_Load Part
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);
RepeaterAccordionPane2.DataBind();
int nUpdatePanelIndex = 0;
foreach (Control crInRepeater in RepeaterAccordionPane2.Controls)
{
if (crInRepeater.GetType() == typeof(RepeaterItem))
{
foreach (Control crInRepeaterItem in crInRepeater.Controls)............

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

What I would like to do is:
From a textbox, I add a name for a product and create a object with that name.
The product object is then added to a Dictionary.
Then, I want to bind this Dictionary to a dropdown list.
If I change the selected item, I want to display the number of the chosen product (Default as 0 when I create the product object).
The problem is that when I try to change the item in the dropdown list, nothing happens.
.aspx
<asp:TextBox ID="productText" runat="server"></asp:TextBox>
<asp:Button ID="newProductButton" runat="server" OnClick="newProduct_Click" />
<div>
<asp:DropDownList ID="ddlProducts" runat="server" AutoPostBack="true"
