Force AutoCompleteExtender Dropdown To Redisplay Via JavaScript?
Oct 19, 2010
I have an AjaxControlToolkit.AutoCompleteExtender control attached to a textbox, and three radio buttons. When the user selects a radio button, the service method used to retrieve the values listed in the AutoCompleteExtender is changed, as follows:
[code]...
but nothing seems force the correct events to fire in order to make the autocomplete list re-display with the results of the new service method. How can I make this happen using Javascript?
EDIT: I should note: the jQuery events are firing correctly in each of the above cases, they're just not causing the autocomplete list to reappear when they do. I figure I haven't yet struck the right combination of events that the autocompleteextender is expecting to force the list to appear.

When AutoCompleteExtender displays the list it is getting hide by the below dropdown.
All the controls on page are dynamic.
So, i cannot hide the other dropdowns to get it work.

Has anyone acheived this before. I am unsure of how to force the onchange in the dropdown to fire some code behind in my controller.

I'm calling a web service called GetTooltip from inside Javascript. However, since the web service is called asynchronously, it doesn't wait until I get the return value from the web service, before it continues again. This is a bit of a problem for me, since the web service is in a for-loop. How do I make the Javascript wait until I hear back from the web service, before letting Javascript continue the for-loop?

I have the following code which should update a label to say "wait..", then run a function, and then update the label again to say it has completed:
<asp:Button ID="Button1" runat="server" Text="Upload"
onclientclick="document.getElementById('errorMessage').innerText='Wait...';"
onclick="Button1_Click" />
This works fine in IE, but not in Firefox.
When I run it in Firefox the label does not change until the process completes.
Is there a way to force the JavaScript to update the page before running the C# function?

I am calling a web service via Javascript. I tried it first in a web page that does not have a Masterpage and it worked perfectly. Then I moved everything over to a web page that does use a Masterpage, and I get a "Microsoft JScript runtime error: Object required" on the javascript statement that calls the web service. My javascript statements look like so:

The web service looks like:

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.

I have an .aspx hidden control that stores a defaultId for this dropdown. However, the values in the dropdown can change and sometime the defaultId is listed as one of the selections, other times it isn't. When the drop down clears we run this to reset it:
Global.getComponent("ddlVehicleType").setValue(Global.getComponent("DefaultVehicleTypeId").getValue());
Now when it sets that, if the dropdown doesn't have a value associated with that Id, it displays the actual Id in the field. I have a check for isNumeric now to see when that happens, but how do I make the field display the first value in the list of Id's it DOES have:
var displayedValue = Global.getComponent("ddlVehicleType").getRawValue();
if (IsNumeric(displayedValue)) {
}

I have a dropdownlist and a gridview with a drop down list in every row. I have removed other cols in Grid for simplicity.
Whenever a new value in the dropdownlist is selected I would like to set all of the dropdownlists in the gridview to that same value via javascript. (Yea both the dropdownlist outside the gird and the ones inside the grid are populated by the same data source)
The dropdownlist:
<asp:DropDownList onchange="javascript:onJDSelection();" ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource4" DataTextField="circt_cstdn_nm"
DataValueField="circt_cstdn_user_id">
</asp:DropDownList>
The GridView:
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" onrowdatabound="GridView2_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Change to Job Designer" SortExpression="circt_Cstdn_nm">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("circt_Cstdn_nm") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:DropDownList ID="ddl_jd" runat="server" DataSourceID="SqlDataSource4" DataTextField="CIRCT_CSTDN_NM"
DataValueField="CIRCT_CSTDN_user_id"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
My current attempt:
function onJDSelection() {
var jd = document.getElementById('ctl00_MAIN_DropDownList3').Text;
var grid = document.getElementById('ctl00_MAIN_GridView2');
for (var i = 1; i < grid.rows.length; i++) {
grid.rows[i].cells[0].getElementsByTagName("*")[1].selectedText = jd;
}
}
[Code]...
When clicking on the dropdown I get an alert that says "test" and an alert that says "[Object object]" However nothing happens with the dropdowns in the grid and the alert(i) never fires.

i am using the function history.go(-1) function on my button to go back. but i am getting a prob in value selected in dropdown.
the sourceview is showing the original value selected but on UI its showing the previous value
means when i click on back button,
UI shows the same value but when i view the source code then the selected value is the same that need to be appear
for example
suppose my dropdown has data in format MM/YYYY first i select 02/2010 and then after that i select 04/2010 now when i click on back button having onclick ="history.go(-1)"
then the value in dropdown remains the same i.e 04/2010 but when i see the source code, then for dropdown the selected value shows as 02/2010.

I've 2 dropdownlists, both are binded to a cascadingdropdown. Whenever I select an option in the 1st dropdownlist (parent), the options in the 2nd dropdownlist (child) will repopulate based on the options I selected in the parent dropdownlist. I need a javascript function to reset the options of both dropdownlists in their initial state (the prompt text).
I've tried changing the selectedIndex of the parent dropdownlist. However, this only changes the selected option in the parent dropdownlist. It does not reset the child dropdownlist to its initial state (which is supposed to be disabled and without any options). Need the script to reset the chained dropdownlists?

I have a dropdown list with a piece of code that is run when the value is changed:
<select name="SList" onchange="javascript:setTimeout('__doPostBack('SList','')', 0)" id="SList">
Everything works fine when manually done. As an option is selected, the onchange code is called.
The problem begins when I try to change the selected value using a piece of Javscript. I want to be able to automatically change the selected option using JS, whilst still having the onchange code called, exactly as if done manually.
I try calling this:
form.SList.value = "33";
The right option is selected, but the onchange code does not get called. So then I try doing this:
form.SList.value = "33";
javascript:setTimeout('__doPostBack('SList','')', 0);
The right value is not selected and nothing happens.
FYI, the code is done in ASP.NET and Javascript.
What can I run to change the selected option whilst still calling the onchange code?

I'm back with my CascadingDropdown problems.
This one must be the last but not the less annoying.
I have a set of dropdowns ruled by 3 CascadingDropDowns extenders.
I would like to change the value of these dropdowns by javascript.
This works for the parent dropdown but not for the others.
Here is the javascript code used :
$find(element_name).set_SelectedValue(valeur,valeur);
$find(element_name)._onParentChange(null,true); // still wonder what are the parameters for...
This code does not give me any error but nothing change on display.
The strangest thing is that when I check the value of my dropdown with firebug, I get this :
<input id="Pane2_content_CONNEX_ClientState" type="hidden" name="Pane2_content$CONNEX_ClientState" value="D:::D:::">
And the value that I set is "D". But on the webpage, the dropdown displays a "A" which is the last selected value.

Eg:-- When I type "A" all the elements starting with A should be displayed... If "B" then elements with B....etc)
Ex:
<asp:DropDownList ID="ddlLocation" style="width:140px" runat="server">
<asp:ListItem Value="1" >India</asp:ListItem>
<asp:ListItem Value="2" >India - Hyderabad</asp:ListItem>
<asp:ListItem Value="3">South Africa</asp:ListItem>
<asp:ListItem Value="4">Australia</asp:ListItem>
</asp:DropDownList>
javascript :
function DisplayText()
{
var textboxId = '<% = txtText.ClientID %>';
var dropdownListId = '<% = ddlLocation.ClientID %>';
document.getElementById(textboxId).value = document.getElementById(dropdownListId).value;
document.getElementById(textboxId).focus();
}
code behind :
ddlLocation.Attributes.Add("onChange", "DisplayText();");
