View 4 RepliesI 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.

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
i have a dropdownlist (asp.net control) and a listbox control and a Add button when the user select the item from dropdownlist and click on add button to add to the listbox.
how can i prevent the user from adding duplciate items and alert saying its already in the listbox?
UPDATE:
in my particular scenario, i have a dropdwonlist and adding the item to listbox both are asp.net controls and i am adding the items from code-behind and your solution is pure on client side, is there a way i can read the listbox and compare and alert the message?

I am trying to implement the autocomplete method for textboxes.
I would like to use the example based on jquerys autocomplete provided here
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
});
});
</script>
</head>
The first and Main problem is that i do not know the way of passing my values to the source:
By saying that i mean, supposing i have a a server-side ASP.NET function GetTheResults as listof(string) or GetTheResults as string ()
how am i supposed to pass those values as source required by the auto-complete?
The second problem is that the specific way does not use AJAX.
Which means i guess on the load of the form i will load all the available values to the source. Isn't that an overkill?

View 1 RepliesI 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.

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.
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?

I am trying to add default item 'All' to my RadComboBox. It is adding at the end and also it doesn't select this default item. What could be the problem?
function OnClientItemsRequested(sender, eventArgs) {
var combo = $find("<%= RadComboBox1.ClientID %>");
var intextput = "All";
var comboItem = new Telerik.Web.UI.RadComboBoxItem();
comboItem.set_text(intextput);
comboItem.set_value("");
combo.trackChanges();
combo.get_items().add(comboItem);
comboItem.select();
combo.commitChanges();
comboItem.scrollIntoView();
}
<telerik:RadComboBox runat="server" ID="RadComboBox1"

<WebServiceSettings Method="GetMyData" Path="http://localhost:1606/Service1.svc" />

I'm using a DropDownList with a data source which successfully populates the list. However, I want one of the items to be selected, namely the one where the value matches the path and query of the current request.
ddlTopics.DataSource = pdc;
ddlTopics.DataBind();
foreach (ListItem item in ddlTopics.Items)
{
item.Selected = item.Value.Equals(this.Page.Request.Url.PathAndQuery);
}
Using the debugger in Visual Studio 2008 reveals that item.Selected becomes true exactly once in the loop, but the rendered select has no option that is selected.
I have an <asp:Menu> object on my webpage and it works but it has a very minor shortcoming that is very irritating.
Currently, the menu item is activated when the user clicks on the TEXT of the menu item (Home for example). However, the menu item does not allow me to click on the menu item when I put the mouse over the rectangle which the menu item is in but not on the text.
So if I click on the WORD Home, it works.
When I attempt to click right next to the word HOME, it does not work. I know that I am in the menu item rectangle because I change the background color when hovering over it.
Is there a way to have the menu be active when the mouse is anywhere in the menu item?
Or am I limited to only being able to click on the menu item hyperlink ONLY?
