Select Item In CascadingDropDown Via JavaScript And Invoke Update?

Mar 17, 2010

In code-behind I can do this to select something:

// Select item in first DropDownList
myCascadingDropDown_1.SelectedValue = itemValue_1+":::"+itemText_1;
// Select item in second DropDownList
myCascadingDropDown_2.SelectedValue = itemValue_2+":::"+itemText_2;

How can I do this in JavaScript?

EDIT:

I can select my desired item in the first dropdownlist. The problem is however, that new values based on that selected item (it is a CascadingDropDown, remember?) don't show in the second dropdown so I can't select anything there. I would need to somehow invoke the update method of the second dropdown manually.

Javascript - Changing Color Of Selected Item In Select Elm?

Dec 6, 2010

I simply am trying to add a color to the select item background within the select elm after a user makes a selection from the select elm. The result right now is that in firefox, the colors will change, but only during selection ... after the selection has been made the background for the individual selection is still white.

This code works fine in IE but so far my efforts have been thuarted in FireFox.

[code]....

P.s I made an equivalent javascript method and made some attempts at it, but the result is still the same. The background color of the item is changed ... but only is visible when making a selection, NOT after the selection is made.

.Compliant { background-color : #8AC9FF; }
.OtherThanSerious { background-color: #C2FF87; }
.Serious { background-color: #FFBC43; }
.Critical { background-color: #FF6743; }

Javascript Onclick To Select Item With ListView Control?

Sep 19, 2010

I'm trying to implement a onclick event to select an item in a asp:ListViewControl.

<ItemTemplate>
<tr runat="server" id="MemberRow" onclick='<%#ClientScript.GetPostBackClientHyperlink(LvMembers, string.Format("Select${0}", Container.DataItemIndex)) %>'>
<td>

[code]...

However the onclick does not fire the ListView.Command or ListView.SelectedIndexChanging event? If I add a button with CommandName="Select" it works as expected? The POST data is the same!

{_EVENTTARGET=ctl00%24ContentPlaceHolder1%24LvMembers&_EVENTARGUMENT=Select%245&__VIEWSTATE=...}

AJAX :: Using Cascadingdropdown To Update Detailsview

Nov 9, 2010

I have two sets of cascading drop down lists they are contained in a detailsview <edititemtemplate>. The problem is that when the user clicks update; the original data is wiped out and the user has to redo the selection of all items contained in a cascading dropdown even if the user didn't want to change that particular aspect of a record. If the user doesn't select everything an error is thrown by the stored procedure in regrds to null values not being valid.

Is there a way i can use cascadingdropdown so that the current values are visible when the user clicks update; meaning that they don't have to redo selections for all items involving drop down lists. The current selections would be default values.

How To Invoke A JavaScript Through A Thread

Feb 23, 2011

I have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.

In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.

I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

AJAX :: How To Update Listbox Based On Dropdown Value / Unable To Use Cascadingdropdown

Mar 15, 2010

i have a religion dropdown1 , on this selectedindexchange i have to populate castes into the listbox(not dropdownlist).

i am unable to use cascadingdropdown as it is tightly binded with dropdowns.

please guide me how do i update listbox items based on the dropdown selected value using ajax.

i tried with pagemethods getting the dictionary object using JS function and thought of binding it.

but i am unable to bind the list.

//html code
Religion
<asp:DropDownList ID="ddlReligion_RS" runat="server" TabIndex="6" onchange="GetCastes_RS(this.value);">
</asp:DropDownList>
<br />
Caste
<asp:ListBox SelectionMode="Multiple" ID="lstBxCst_RS" runat="server">
</asp:ListBox>
//js function
function GetCastes_RS(relgnID)
{
abc.BLL.Services.AjaxService.GetCastes(relgnID,
function (resp)
{
var ddlCaste= document.getElementById("<%=lstBxCaste_RS.ClientID%>");
ddlCaste.length=0;
var castesList = resp;
alert (resp);
if(castesList.keys.length >0)
{
for(var i=0 ;i< castesList.keys.length;i++)
{
op=castesList.keys[i];
ddlCaste.options[ddlCaste.length]=new Option(castesList.values[i],op);
}
}
},
function(val)
{
alert(val.get_message());
}
);
}

i could call the webmethod, but i am getting this error in javascript.

Type 'System.Collections.Generic.Dictionary`2[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089]]' is not supported for serialization/deserialization of a dictionary, keys must be strings or objects.

when gone thru few links i have seen few examples supporting dictionary object , why not in my case?

MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

Web Forms :: Invoke JavaScript Function From ActiveX Control

Mar 4, 2010

I have to fullfill a requirement where my activeX control (developed in c#) need to invoke a callback JavaScript function asynchronously (or) synchronously (or) in both ways. I can handle the context using threads. JavaScript:

function handler_1(){ ..... }
myActiveXObject.registerCallBack(handler_1);

Where in ActiveX control, I need a function "registerCallBack" to accept the argument. But I have no clue how to invoke that registered JavaScript function from my ActiveX control. By digging MSDN forum, I found something as script.GetType().InvokeMember("myJSFunctionName", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public, null, script, null);

the above line throwing me an exception Unknown Name etc. I do have the definition for "myJSFunctionName" in javascript and I got the script object from the document object.

C# - Cannot Select The ComboBox Item

Sep 14, 2010

I have two Comboboxes where the second one is dependent upon the first one.

When the SelectedIndexChanged event of the first Combobox fires then the second Combobox will be enabled.

After the event, the second Combobox is enabled but I cannot select the ComboBox item.

EDIT

I use Dev express Tools

First Combo I load in Page_Load Event

I use Server Side code:

protected void ASPxComboModule_SelectedIndexChanged(object sender, EventArgs e)
{
LoadSecondCombo();
LoadSecondCombo.Focus();
}

There is no problem in loading, but I'm unable to select 2nd combo item.

MVC :: Calling A Select List Item?

Dec 26, 2010

I have created the following select list item on a controller. code goes here........

select new SelectListItem
{
Value = c.Status_ID,
Text = c.Status_Description
};

And i made the required modification to the view and the select list was displayed successfully.But i faced the following two problems:-

1. i need to use the same select list in more than one controller , so for now i have to insert the same code in each controller to add the select list, so is there a way to define this select list in one place and then reuse it in all the related controllers

2. when i select a new value from the select list and i click on save button , the old value for the list will still be displayed ,and also no effect to the DB will be made.
