C# - Unable To Select The ListBox Selectedindex In C#

Mar 19, 2011

I have one ListBox which has three Items in it. And also has one GridView and One Button.

I want to move the selected items in the listbox to the GridView when the Button is clicked.

Now the problem is, if I selects the third item in the listbox and clicks the button, It always moves the first item in the ListBox to the GridView.

How to solve this?

<asp:ListBox ID="lbDrawing" runat="server" AutoPostBack="false" Height="260px" TabIndex="12" Width="150px"></asp:ListBox>

In the Button click event, I select the item by the following C# code,

string itemsname = lbDrawing.Items[lbDrawing.SelectedIndex].Text;

I fill the ListBox based the DropDownList SelectedIndex Changed Event. So I can not bind the ListBox in the Page is not PostBack Block.

C# - Changing The SelectedIndex Of Multiple Select Listbox To The Last Selected Item?

Jan 18, 2011

Referring to a C#, .net, System.Web.UI.WebControls.Lisbox which has a multiple select option true and needs to do a postback every time selected index changes.

Problem is, the [SelectedIndex / SelectedItem / SelectedValue] is always on the value of the 1st selected item. Clicking on the second item, third item, does not change the SelectedIndex, causing the listbox to reload and scroll to the highest selected item position.

ListBox Dosn't Fire OnSelectedIndexChanged Event When SelectedIndex Is Changed?

Aug 24, 2010

I have an asp.net page with a list box on it. Multiple event handlers subscribe to its OnSelectedIndexChanged event.

When I change the SelectedIndex programmatically none of the events get fired.

Now a hack for this is to call each event handler, but this has already caused bugs since people didn't know they had to do this when adding a new event handler.

I can do this in a Winforms app and even when SelectedIndex is changed in code the events fire.

C# - ListBox Is Null In Select Method Of ObjectDataSource?

Jan 14, 2010

I couldn't come up with a good subject. I have a simple ASP.NET 3.5 form. If you follow the numbered comments, I explain how I am stepping through the code when I run the page in debug mode. Both of the below functions are methods declared in the code behind file of the page, both are in the same _Default class. The ManagersListBox is declared in the Default.aspx page. Why is it that in the context of the GetSubordinates, the ManagersListBox is null? It's as if it disappears for a moment and then reappears after returning from the GetSubordinates method. Obviously the solution is to parameterize GetSuborindates, but that is not my concern. I am trying to learn how ASP.NET works and I would really like to understand why I am seeing this behavior "disappearing object".

Web Forms :: How To Pre Select A Drop Down Listbox Item?

Feb 18, 2011

How can I pre-select a drop down list box item in a listbox? I experimented using Asp.net and C#, but was not able to pre-select a drop down listbox item.

I am not on my coding box right now, but basically as an example of what I am talking about, if I have the following drop down listbox items.

--Select--
New York Jets
New England Patriots
Green Bay Packers
Atlanta Falcons
SF 49'ers
Oakland Raiders

How would I pre select the team name of "Atlanta Falcons" using C# and Asp.net? Spefically based on the string of the team name "Atlanta Falcons" instead of an alternate way like using the Selected Index function?

}
myList.ForEach(delegate(string n)

WebMatrix :: Html.ListBox Cannot Select Multiple Items?

Nov 10, 2010

I'm trying to use the ListBox html helper in a simple form.

verhuurPrijzenLst is a simple list that gets put into the ListBox, I think I need "MultiSelectList", but I cannot use it (MVC framework needed)?

I don't know exactly how to do that ( bin folder and @inherits ? )

So it's nice to have a helper at hand, but if you cannot use it properly without using the MVC framework, that is a pity.

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?
