Persisting DropDown List attributes accross page Postbacks

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :ASP.Net

Can anyone advice how can DropDownList attributes be persisted accross page Postbacks?


DropdownList1.AutoPostBack = True

On Postback the attribute is no longer available (ie. attributes.count=0).
I tried persisting using the code below, but was unsuccessful:

Before PostBack: ViewState.Add("DDL","DropdownList1")
On PostBack: DropdownList1 = ViewState("DDL")

This generated the error: DropDownlist is not marked as serializable.

I than tried:

Before PostBack: Session.Add("DDL","DropdownList1")
On PostBack: DropdownList1 = Session("DDL")

This did not err but attributes were still not available.

Ideas Anyone?

Dropdown list in ASP.NET - How to get value selected

am sure this must be very simple, but unforunately I can't figure it out.
I have the following code which populates the dropdown lists from the database. This works fine. Now, when the user selects a particular employee name from the list, I want to get the Employee Id of the selected employee. i.e. I need to get the "Eid" value. I can do this if the EId is loaded in the dropdown list, but in this case only the employee name is displayed. Please let me know howI can get the Eid value even though it is not loaded in the dropdown list.
I would really appreciate your help

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

Populating Dropdown List using FK


Hi Folks,

2 Questions. I am trying out Data Entities in VWD 2010 Express. I have a parent (Customers) and child (Orders) table. Customers table has FirstName, LastName and Email columns.

Q1. When I view/edit/insert an Order, it shows the customer's first name in dropdown list whereas I want the full name. How can this be done?

Q2. How can I change the default behavior of PK/FK relationship so that customer's Email is displayed instead of Name?

Any help will be much appreciated.

Attach Workflow to Task List, don't get option to manually start workflow via dropdown on task item



I am running WSS 3.0 with other workflows which are functioning correctly.  I created a new workflow in Visual Studio 2008 and was able to successfully run it in my dev environment.  I attached the workflow to a task list in my dev environment and was able to manually start the workflow by using the drop down workflow option and using the menus to manually start it.  I installed this workflow in our production environment and attached it to the task list (which had a SPD workflow attached to it which stopped working about a month ago).  I made sure that the option to manually start the workflow was checked.  When I tried to manually start the workflow, (hover mouse over title, drop down) there isn’t a workflow option.  The workflow also will not start automatically when a task is changed.


I attached this same workflow to a different task list in production and get the option to start it.


I have tried creating a small workflow in SPD 2007 and attaching it to the task list.  It shows that it is attached, when I look at the workflows that are attached to the task list, but I still don’t get the option to manually start it.

Filter web parts in new form page of a list



I've created 2 custom lists. The 2nd list has a lookup column from the 1st list. In the new form page for this 2nd list, I've added the 1st list as a web part. Now, I want to connect the 2 web parts, but it's not available. Basically, what I wanted is that when I select an item on the lookup column, the webpart containing 1st list would show that item on the same page.

I think I'll need to use Sharepoint Designer to implement something like this, but just wanted to check if anyone has done something like this using browser only.



Slow page load during a list query one time during the day


We have a monitoring tool set to check to see if the home pages for our 3 web apps load in under 60 seconds every 10 minutes.  All 3 web apps load in under 3 seconds on every 10 minute check except for one exception.  One check every day one of the web app's home page takes longer than 60 seconds to load.  This happens at 11:45PM when there is very little user usage on the environment.  The characteristics of this page are as follows: The only thing on the page is a list view web part which was added by the browser.  The page has not been customized with SPD or code at all.  The list that it pulls is a simple links list that has 281 items on it.  The view pulls all 281 items and displays them in sets of 100.  I cannot find any associated event in the server events and/or SharePoint ULS logs nor are there any daily sharepoint timer jobs running at that time.  Our full index happens at midnight with incremental happening hourly.  Our enviroment is 2 WFEs, 1 App/indexer and we have a separate SQL cluster backend.  

Could someone lead me possibly in the direction I should take next in my troubleshooting?

Retain DropDown,TextBox's previously selected values after redirected from another page.


 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   



 Update: I've come up with this code. But the problem is The values are being retained but the Button_Click event is not being handled properly. When i Check the code even after this "DropDownList1.SelectedValue = Session["Name"].ToString();" DownList1.SelectedValue is EMPTY"" samw with DropDownList2 . please Suggest something


    protected void Page_Load(object sender, EventArgs e)
        if (IsControlsEmpty())
            if (SessionExist())
                DropDownList1.SelectedValue = Session["Name"].ToString()

Need to remove databinding of DropdownList when another dropdown list changes


I have many controls on my form, but in particular, I have 2 dropdownlists.  1 dropdown list has 2 values, and each value controls what the second dropdownlist displays.  This is an edititemtemplate and both dropdowns have the selecteditem set via '<%# Bind("fieldname") #>' on page load.  

THe problem is, if I change the value of the first dropdown, it errors out because the second dropdwon has a bound value that is no longer acceptable. 

Can I cancel the bind of the second control, if the the first one is changed?  I would like to cancel the bind, and update the values by using a different datasource depending on the value of the first dropdown or hardcode the new values.



If Dropdown1 has a value of "A" for example Dropdown 2 Shows Values "1", "2", "3"

If Dropdown 1 has a value of "B" , Dropdown2 Shows Values "4", "5", "6".

It binds fine initially, but if I change Dropdown1 from A to B, I want Dropdown2 to show the new values, maybe with a default of "Select an Item" and not error out b/c it's attempts to bind a value of 1, 2, or 3.


Hope this makes sence, b/c I'm
