View 13 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.
Database Table: This data has been imported using Link to SQL

May be it's the same question i have i asked before but the issue is the same and i didn't find any resolution so i have to write it again with the expectation that it would be solved this time.My question is i am using two list boxes and one list box is populated by putting the list the list item tag in listBox1 on aspx page and i want to implement functionality like add and remove between two list boxes i mean removing an item from listBox1 should be added to second and removing an item from second should be added to first. While i tried my own but the problem is that on post back it come to same condition. I have implemented the add remove functionality by using the jQuery but the problem is that on post back it come to same condition so i want a good solution for this ow should i implement this so that on post back it retain it's value please ris me off from this issue.I found some solutions for this on Google that i should make some other class which will extend ListBox base class but i couldn't understand that and how should i code for that so please explain me that code if possible.
View 1 RepliesI have a website installed on one of our sales guys laptops and am having issues with the website hanging if left for 2 minutes. This doesn't happen on my dev box, my live machine or the other sales guys machine.
The website will hang. It's not just limited to this page, it will happen on all pages when I leave it for more than 2 minutes and then try and process a page that calls back via button or drop down ect. I have checked the IIS settings of the machine and everything seems the same as the other sales guys machine who is running the same version of the site.
Here are the specs:
Dev Box: asp.net 2, windows server 2008 64bit
Live Box: asp.net 2, windows server 2008 64bit
Working Sales Guy: asp.net2 windows 7 64bit
Broken Sales Guy: asp.net 2 Windows vista 32 bit (the only thing I can see different is windows version)
EDIT: For more information, if I stop the website from trying to load while it hangs, clear my history for the last hour and then refresh, the page comes back fine.
EDIT2: I have just spat out some debug information and it seems it doesn't even go into the post back I need.
EDIT3: This doesn't seem to happen when using Chrome but does when using IE and Mozilla.
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories()
{
StoreDataContext db = new StoreDataContext();
var a = from c in db.Categories
orderby c.Name
select new{catName= c.Name,
catId=c.CategoryID};
ddlCategory.DataSource = a;
ddlCategory.DataTextField = "catName";
ddlCategory.DataValueField = "catId";
ddlCategory.DataBind();
}
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
I have 2 cascading dropdown lists (ListA and ListB).
The selected value from List A is used to determine ListB.
I am wondering if there is a way to dynamically remove items from ListB after ListA value is selected. There are entries in ListB that should not be available unless the user has certain security permissions.
I have an aspx page for Search Options. There are three aspx Dropdown List Controls that are each bound to seperate data sources. The selection made in the Dropdown control is used in a SQL Query within a GridView data source to display the results list.
When I select an item from the drop down list I get the search result, but I want the drop down list to return to it's initial state after it displays the result, so the next selection made will clear the results list from the first selection. I have tried a number of different approaches, but no success. Seems like this should be easy, but I'm new to coding.
I have found a couple of possibles on the forum, but they didn't work. Not sure if you can make any sense of this, but I'll try to give you something more to go on. All I really want to do is reset the dropdown after it displays the results of the search, which I assume is after a PostBack. Here is what I have tried in the Code Behind or Script.
This for just one of the Dropdown Lists, ID=Practices. I have been trying to make this work for way too long. Also, I have tried it with AutoPostBack set to true but same problem. Currently have a 'Submit" button on the page to initiate the search.

I add cascading drop down in a place holder during page load. When i submit the entire form, i found out that my drop down list is reload and my selected value is not selected.

My drop downlist code as follows:
[code]....
* My proble is when I Change the Index Selection My dropdownlist automatically post back and it loses its Selected Index and move to Index=0
* When I press any server control e.g. button it also behave as previous.
my code as below:
1) I have set EnableViewState = True
<%@ Page Language="VB" MasterPageFile="~/en/en.master" AutoEventWireup="false" CodeFile="product_detail.aspx.vb" Inherits="en_product_detail" EnableViewState="true" %>
2) I have set AutoPostBack & EnableViewState = True
<asp:DropDownList ID="ddl_order" runat="server" AutoPostBack="true" EnableViewState="true">
</asp:DropDownList>
I have a page where in there are various entry fields like name, registration number, country, state etc whcih are mandatory. On selection of country in dropdown,the state dropdown is filled and in the phone number boxes the country code is also filled simultaneously.
When I click on Save button it shows the required fields respective messages in the validation summary. When I select the country the state and country code are filled and the validation summary vanishes though I have not entered text in the other mandatory fields. None of the required fields messages are displayed though all fields except Country state and country code are filled.
I have 3 drop downs in a details view (populated from a gridview) during insert mode.
Dropdown 1
Dropdown 2 --> Based on drop down one
Dropdown 3 --> Based on drop down two
I am curious of how to handle the autopostback to update 2 and 3 since they are part of the detailsview, there isn't a selected_index_changed event.
I am ok with adding items to them on page load, just not for cascading of them...
Based on the image, how to select the value from dropdownlist, then tick the checkbox and update the value ?

View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I am facing a problem with jquery bubbleup plugin....
My goal is to show selected item text in a bubble up on the top of the asp.net dropdown list...
I did it on the server side and its working fine....now i want to do it in a nice way using jquery....
I am not concern with only bubble up...
anything which shows my selected item text in the dropdown list...because some text in the drop down is very big and we are unable to see it..
I do have around 10 dropdown lists on my page and all are inside formviews...
so its better to operate on class selector...like $('.mydropdown').val();
I have set the Dropdownstyle to DropDown but its still not highlighting the item in the list
<ajaxToolkit:ComboBox ID="cmbstudentid" runat="server"
AppendDataBoundItems="True" AutoPostBack="True"
Font-Names="Tahoma" Font-Size="Small" [code]....
i am making a web page in which there is a dropdown list and a text box.i want to display the selected item in dropdown and textbox in a Gridview.
