View 2 RepliesI have two databound listboxes. I am able to move items between them using add and remove buttons using for loops. However I have no idea how to commit the items back to the db when the user finally clicks on the Save button on the form.
View 5 RepliesI am having a lot of trouble with a seemingly simple thing. In an ASP.NET webform I have two ListBoxes, with Add and Remove buttons in between. The user can select items in one ListBox and using the buttons, swap them around. I do this on the clientside using javascript. I then also have a SAVE button, which I want to process on the server side when the user is happy with their list.
Problems : First I was getting the following problem when I clicked SAVE :
Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I read that one of the methods to get around this was to put my ListBoxes into an UpdatePanel, which I did, and I am getting further.
However, now the event handler for the button's Click event is not being run if the user has used the clientside javascript to alter the contents of the Listboxes. If the user has not altered the contents of the listboxes, the handler does execute.

View 1 RepliesI have a datagrid that has photos and a description of the individual in the photo. I have a procedure that works and if I execute it with the correct parameters it changes the rows in the table. I have a datagrid with two image buttons, MoveUp and MoveDown. I just want to be able to reorder the photos when needed.
In my proc called "MoveMember" I have these parameters that are passed in. The column that gets swapped in my table is the "OrderBy" column, they are just numeric numbers 1,2,3,4 etc.
So in my procedure 2 and 3 can be interchanged.

I have two drop down listboxes in a GridView control. I want to populate the second drop down listbox based upon the value that was selected in the first drop down listbox. Currently I have not been able to populate the second drop down listbox. I am attempting to do this in the C# code file. See line 26 below.
// Here is some of my Aspx code:
this first item template populates the first drop down listbox:
<ItemTemplate>
<asp:DropDownList ID="ddlFirstDropDown" runat="server"
DataSourceID="SqlDataSourceBodyBuild"
DataTextField="BodyPart" DataValueField="EmployeeId" AppendDataBoundItems="True"
Width="110px" AutoPostBack="True"
onselectedindexchanged="ddlFirstDropDown_SelectedIndexChanged">

I have a detailsview with a checkboxlist
[Code]....
As you can see, it is populated by a method. This method checks whether the item is checked or not (when updating the data shown in the detailsview)
[Code]....
Now when I click the update button, the button that triggers the itemupdating event, I delete all links in the database connected to that record, loop through all my checkboxlists and insert the ones that are checked:
[Code]....
The problem however is in this line:
[Code]....
For some reason the items are counted double and I cannot find the reason for that. Dividing it by two does solve it but it would be nicer to understand why it does that.(And if there would be a better way to loop through all the controls to find all checkboxes.

how to reorder a datadrid, by moving one row up or down.
View 1 Replieswe need to move Gridview rows up or down by selecting the same.
we have two buttons as up and down.
After selecting a row(index(X)) then if we click up the row(index(X-1)) will come down and row we selected will move up.
same case with the down button ,After selecting a row(index(X)) then if we click up the row(index(X+1)) will come up and row we selected will move down.
all these changes has to reflect on database(order of records stored) also.
I have a DropDownList on my webpage using an Access Database to fill it. However in my database record there a multible values with the same name.

He has a drop down list and a textbox in the header of a GridView. I am able to do this if i create a new column and put the controls in the Header Template.
However I would like my column to span across the entire GridView.Columns.Count instead of having an unsightly single column.
I have some global variables declared and want to access them in subrorutines using the For statement.
For example, I want to use the following to place values in the global variables , i.e, dblcell1, dblcell2, dblcell3, etc.

I'm trying to build a small back-end page for adding business references to 'portfolio' front-end page.
I chose the GridView control for displaying current items, and am currently working on positioning code(display order) with button fields up/down.
The up/down button code works fine until the GridView is sorted by clicking the header field, then it breaks.
Here is the relevant code:
[Code]....
I am trying to get an idea on the best way to do the following:
[1]I have a list of object type (my_object_type), one of the my_object_type members is called SortOrder, which corresponds to the location within the list.
example of List<my_object_type>
SortOrder=1 | item2="something" | item3="something"
SortOrder=2 | item2="something" | item3="something"
SortOrder=3 | item2="something" | item3="something"
SortOrder=4 | item2="something" | item3="something"
SortOrder=5 | item2="something" | item3="something"
SortOrder=6 | item2="something" | item3="something"
[2]I bind this List<my_object_type> to a GridView, that looks something like the following when displayed:
[1]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[2]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[3]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[4]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[5]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[6]|[something]|[something]|MOVE TO [DropDownList 1-6]|[Move Button]
[3]When I select a drop down list item from column 4 of the GridView and then select the MOVE BUTTON, I would like to be able to move an object to a specific NEW location - basically reorder the List<my_object_type> and then BIND the new List Order back to the GridView.... (example: current list item #3 -> select #5 from drop down list -> press Move Button ||| then BIND changes back to the GridView)
Question: any recommendations about the best way of doing this within the gridview, etc...?
I've some webpage with listview control, and double click event on each row on it.
The problem is, that when I double click the row, event is fired, that's fine, but all of the page is selected (dark blue marked, you know...).
Is there some solution to prevent select all in the whole page, or whole aplication itself?
I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.
Is there someway that I can control the action of the "Enter" key so that this will not happen?
Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
on aspx page:
private
static string __VIEWSTATE_FETCH;
protected void Page_Load(object sender,
EventArgs e){
[Code]....
I'm writing few custom controls. The server controls inject javascript so that the postback can happen as everyone know.
Is there a solution to move this script to a seperate js file?

Im using Microsoft Expression Web 3 and am in the process of making a page for my Cab Company that basically calculates the price from an area in London (In listbox A) and an airport (In listbox B) along with the type of car used (Saloon, Estate, MPV) in a checkbox list.
If I were to set a value for each and every item in Listboxes A, B and Cars, is there some sort of autosum code I can use which calculates the price. The feature is only going to be a pricequote system for now untill we get some sort of booking system up and running so it is preferred that all calculations are done & displayed on the same page.
I have a grid containing images loaded from database. the images are displayed in the order as they are stored in the database. Is there any way to change the order of the images manually once after they are uploaded to the database.. the admin before publishing the images to front end, should be able to arrange the images as he/she wish and then finally stores them in database.
View 5 RepliesI have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors

I have a web app that has two listboxes on the page. The first listbox has selection items that can be chosen and moved over with back and forward buttons to the destination listbox.
I can't figure out how to validate the destination listbox for empty items on a postback. I have tried to use a custom validator, but I can't get the validator to fire unless I actually select one of the items with the mouse.
