Web Forms :: Changing Dropdowns Option When Click Other
Jan 19, 2010
I'm currently writing a website with two linked drop downs, when you click one it changes what options can be used in the second one, that's all find and dandy however i need to have the option for an "Any" (*) option in both of them, I did have it working with appenddataitems turned on and "
<
asp:ListItem
Enabled=true
Selected=True
Text="Any"
Value="*"
/>
"
however this causes problems as you click an option in the first dropdown then change it and the second drop down keeps the options for the first selection aswell. Am i going to have to live without the Any option in the second box and put in code if firstbox.text = "Any" then Secondbox.text = "Any" (when it comes to doing the search on the database?)
I am using panel to hide and display certain controls on a page, On one of my panel i have three drop down, all i want is to make sure that user has selected something from the dropdowns otherwise they cant proceed, i am using the requiredfield validator but its just not working
'm using a gridview with paging and sorting in asp.net (language = VB).The gridview shows all the artists in my database. I've added a searchbox above my gridview, so users can search for certain artists by name.The search option works. If I enter the name: John --> it shows the artists who have the name John.Now for the problem:If the user filtered the gridview (for eample searching for John) and switches to another page of the gridview, the gridview is again filled with all the artists instead of the artists that are named John.
I have 45 dropdown lists in my asp page. There are some methods that I can apply to all of these dropdowns. Is it possible to convert them into an array of dropdowns for ease of use?
I have a gridview connected to a sql database that allows the user to delete the record. I used the ASP.net automatic "options" for this. However, I would like when the user deletes a record, a message (textbox) appears in the form to say the record has been deleted.

After clicking one of these buttons, my wizard ActiveStepIndex have to change. This is no problem.
[Code]....
But now I would like to change the buttons background-color after clicking one of them. This is no problem too, but if I click the next button, the first button background color must change to white. But it does not do that. It remains constant #cccccc.
Only the button, whitch I have clicked should be #cccccc. The other buttons should be white.
In my web page, i am retreiving values from database in textbox. I have one update button in that page when i change the textbox value and click on button the value does'nt change it is taking the same value. What is the problem i did'nt understand?

I have a asp.net page - manageCustomer.aspx with a button 'SyncCustomers'. When this button is clicked, customer records will be taken one by one from one database and syncd with another database. As it is a long running process, when this button is clicked and process starts, I want to show present status in a label box of the same manageCustomer.aspx page. But inside this button click event, where I have codings for this process, when I try to update text of label box, its not changing in that page. only when all process were completed,last text that i gave for label box is displayed. So, How to give updates of running process in a label?
I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)
I am fetching date from oracle and putting it into a textbox. That textbox is takin value as dd/MM/yyyy format by default. Then I am storing the value in a viewstate.
There is a submit button on the page at clicking of that I am passing the viewstate to a function with explicitly converting it to the datatable.
When I click on the submit button for the first time. View state is capturing date in dd/MM/yyyy format and everything go on well. After the button click event completed.
Now if i agaian click on the submit button then viewsate is having date in MM/dd/yyyy frmat. Dont know how it is getting changed. Due to this format change I am facing issue in my bussiness logic and data access.

I have several dropdowns on a page that I have named dd1 - dd15. They all have the same data source, so I created a class to get the source and now I need to loop through and load each one. I think I might be close, but could use a push. Here is my class:
I just recently upgrade my asp.net web project from visual studio 2005 to visual studio 2010. The upgrade was successful with no problems however im missing some features with this project. The One Click Publish feature(which is greyed out) in the header area of Visual Studio 2010 and the Add Config Transforms feature which is no where to be seen when you right click on web.config. When i create a new web project straight from visual studio 2010, these options work fine.
I have a form in which I have two drop downs. A decision in one fires the other. The basic rule is:
Drop Down A -> select items 1,2 or 3. Drop down B loads list 1 Drop Down A -> select items 4,5 or 6. Drop down B loads list 2
This works fine on first load and save of the form. The problem is when I edit. Lets say I selected and saved item 3 in Drop Down A. On Editing: If I change Drop Down A, the select changed event fires every time I change it except when i reselect what was saved. It leaves me in a situation where I can choose 3 in Drop Down A but are left with the wrong list in Drop Down B as the event doesn't refire on that selection.
I've tried every trick I can think of but I can't seem to get around this issue. (We've tried radiobutton lists and its the same issue. Setting the value in a variable and attempting to reset the control to clear what it thinks the original value is doesn't work either.)
I have figured out how to programmically hide a dropdown on same page and on a different page using a Session when the Dropdownbox im using has a static drop down list. I am, however, having issues with a dropdown that is data bound to a DB for the dropdown list.I have gone over the code many times and that seems to be where my issue lies.
Here is where i set the selected item to a session on one .CS page:
I am having slight trouble with the menu control on a website which I am developing. In IE 8 the text doesn't appear in the dropdowns. This is intermittent between two different nodes. :S I have added the z-index: 1000; fix, but it doesn't seem to have any effect. The site is currently here: watercress.lukestratton.co.uk , please don't pass the URL around. This is fine in ALL other browsers. I think it may be something to do with my CuFon font conversion scripts.
I got a web app linked to a SQL Server 2005. The registration page for learners on this page require a lot of information and many of them are on dropdown controls linked each to their own table adapter. The table adapters are linked to tables within the Database. The dropdowns consist of info like designations, grades, categories, race, etc. The tables like designations changes from day to day as new types of designations are added and the other removed. What will the best way be to add data to the dropdowns? Another way I considered are to have one table and add a field like a type field that distinguish between the dropdown so that I only use one table adapter, or are there a better way. Some Code:
I have a webpage used to document work performed on a job. There can be as many as 6 employees for every line of work documented and I have placed 6 ddl's which are all populated with the same list of employees along with 6 text boxes for the hours. I loop through each ddl in the code behind to add the work performed to the server but I'm thinking there must be a better way to do this. I'll add the code for the first two ddl's so you can get an idea of what I need to do.
I have two lines of dropdown menus. There are 3 dropdown in each line (together 6). First dropdown in each line is "independent". The second and third are dependent. If user selects second, page loads and user can then selects item in third. So user have option to select first OR second and third in each line.
.ASPX code:
[Code]....
Since I've found out that you can't validate dropdown controls directly with CustomValidator I've wrote few lines of code for each of dropdowns to insert some values in txtBx_Cln1n2 which will be hidden when the page will be finished.
[Code]....
Unfortunately the code for CustomValidator have some bugs. If user doesn't select anything error message is shown. But if he choose 1 employee and then second and then select (I doubt that anybody will do this but I want to be sure and prevent as much exceptions as possible) the first item in one of the dropdowns ("all employees" or "employees by group") the custom Validator will allow execution of code for link button although the validation code should prevent this.
[Code]....
I know I could this a little better since code is quite complicated if I want to tell the user which employee he/she forget to enter. I've tried instead of SelectedItem.Value also SelectedIndex != 0 but the problems are the same.
I couldn't validate this without the use of textbox. But this method is also making complications since user can select 2 employees and then in one of the selected dropdown change selection to index = 0. Maybe I have to disable viewstate on all dropdowns? But this would probably affect INSERT of data?
I've been trying to figure out the issue and knowone seemd to know. I put a dropdown on my page and when I view it from my server, it works fine. When I tell it to go and get it's values from a DB I can no longer see it on the page when I view it from the server. Here's the code I have for it:
<td class="style28"> <asp:DropDownList ID="DropDownList2" runat="server" DataSourceID="AccessDataSource1" DataTextField="Team" DataValueField="ID"> </asp:DropDownList> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="AccessDataSource1" EmptyDataText="There are no data records to display." Visible="False"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True" SortExpression="ID" /> <asp:BoundField DataField="Team" HeaderText="Team" SortExpression="Team" /> </Columns> </asp:GridView> <asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="App_DataIRISBS.mdb" SelectCommand="SELECT [ID], [Team] FROM [tblTeam]"></asp:AccessDataSource> </td>
