AJAX :: Dropdownlist Selectedindex Changed Will Not Fire And Update Gridview In UpdatePanel?
Oct 6, 2010I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.

AJAX :: UpdatePanel Add Value To DropDownList?
Mar 17, 2010I have a page with an UpdatePanel wich inside has a dropdownlist control. Everything on the page is created dynamically on Page_Init.
DropDownList items are taken from the database with a Select based on some table.
I want to click a button inside the drop down list that inserts a new row in the table that dropdownlist control is based on, and then, on another postback I want the item to appear in the dropdownlist and select it.
On the first button click I insert my row. Ok. On the second button click (I just want to do a postback), in Page_Init I check that the dropdownlist control contains the item I have inserted, and it is there. But in Page_Load event of the same postback I want to set the value selected to be the new value,
but now the drop down list doesn't contain the item anymore!.
AJAX :: Updatepanel And Dropdownlist In A Masterpage?
Apr 26, 2010firstly,i am going nuts with this problem. here it is:
i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.
now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.
i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage

AJAX :: Make DropDownList Change Values In UpdatePanel?
May 19, 2010i have a DropDownList, which is inside an UpdatePanel. Now my problem is that, for example, lets say there are 3 item, Item1, Item2, Item3.
Now Item1 is the default, and i have code in codebehind that gets the value of the selected DropDownList, so for example, my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "UPDATE Items SET ItemSelect = @ItemSelect";
using (SqlConnection myConnection = new SqlConnection(connectionString))
{
myConnection.Open();
SqlCommand HubInsert = new SqlCommand(insertSql, myConnection);
HubInsert.Parameters.AddWithValue("@ItemSelect", DropDown1.SelectedValue.ToString());
HubInsert.ExecuteNonQuery();
myConnection.Close();
}
Now the problem is that, once it is in an update panel, when you change the list to another item, so for example, i changed the list to "Item2", it will still be showing the first value of "Item1", i could have used Autopostback to get what i need, but then i wouldnt see the point in using update panel, since i dont want my page to flick.
Is there a way, or code to write that whenever the value of the DropDownList is changed, and i click my button, it will actually get the currently selected value, and not the virst default value,

AJAX :: Gridview Within Updatepanel Not Triggering Gridview Outside Of Updatepanel
Jan 14, 2011I have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my

Web Forms :: FindControl SelectedItem In Dynamic DropDownList
Jun 5, 2010 First post here, I usually try not posting until I am completely lost. I have a webform that gets a dynamic dropdownlist added to a placeholder in a method during pageload. During a submit of the page, I want to be able to get the selectedItem in the DropDownList that was also added dynamically from a DB. I know the ID of the DropDownList, and I know the Value of all the ListItems. Although when I am trying to use FindConrol(ID), and assign it to a DropDownList, the Control comes back Null and I get an error saying "Object Reference not set to and Instance of an Object", I believe because its not finding the control.
[Code]....
Can anyone show me how to use this to get access to the properties of the dynamic DropDownList properties, especially the ListItems within.
C# - DropDownList Selected Item Incorrect When Using FindControl?
Feb 10, 2010I have a number of dropdownlists embedded in a gridview. When I submit the page I loop through all the rows of the gridview and use the findcontrol method to get the dropdownlist e.g:
foreach (GridViewRow gvrItem in gvItems.Rows)
{
DropDownList ddlOption = gvrItem.Cells[2].FindControl("ddlOption") as DropDownList;
}
This works nicely, however when I try to get the selected item of the dropdownlist e.g:
ddlOption .SelectedItem.Text
It always returns the first item in the list rather than whats actually selecte din the page.

AJAX :: GridView In UpdatePanel Not Refreshing?
Feb 11, 2010Here is the setup:
VS 2008Update PanelIn the update panel, is a gridview, and an asp:panel that contains some other controls, including the button I want to trigger the update of the gridviewThe gridview is tied to a sqldatasource, although I have tried multiple methods to get the data and all failed
Here is the problem:
User logs in and fills out the top part of the form. That submits some data to a table, returns the ID of the row submitted and makes an asp:panel visible (panel.visible=true). This update panel exists inside of the UpdatePanel. The user clicks a drop down list and selects a name. When this happens, another panel becomes visible, using the same process, to allow the user to enter data about the name they selected. So far, everything works.
What Should Happen next:
User clicks "Add" buttonDatabase is updated with the data enteredDatasource refreshesGridview refreshes - It is not visible at load because there are no records for it to show.
What Actually Happens:
User clicks "Add" button Database is updated with the data entered - This has been verified Datasource should update, but not sure it is Gridview does not show.

AJAX :: How To Select Gridview Using UpdatePanel
Jul 28, 2010I have a an UpdatePanel that binds data to a Gridview. Within the gridview I have a select button that will pass the selected id to another Gridview that uses an UpdatePanel. The issue I have is when I select a row in the first gridview one of 2 things occur.
1.) The selection does happen until the Timer refreshes. For instance if I select row 1 in Gridview1, I don't see the 2nd Gridview until the Timer refreshes after 30 seconds.
2.) The selection will happen right away IF I click on the Select button twice. (Don't want this...)
Is there something I'm missing that is causing the first click to the gridview to not select that row immediately? What really gets me is if I put a breakpoint on the Gridview1 SelecteIndexChanged, it fires right away and if I walk through the code it selects it right away.
