View 1 RepliesI'm currently working on a project and I want to make as much things as possible performing on client side - with as little loading as possible. The project consist of three "main" pages. On one page I use jQuery DataTable plugin which is working great. One page has tabs (using jQuery). I want to put datacontrol (repeater) on this site and when user selects one item in dropdown, data in repeater loads on client side, without performing the action on server.

I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?

Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.
So my drop down list looks like;

And then I have setup a datasource (even though I may get rid of it to bind in the code behind file)

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I normally have a function to populate my dropdown list with the database values.
How can I populate a dropdown list so the values are stored in the web config?
The only problem is that the list would need to store two values, the text value of the combo, and the data value.

If I wanted to add a new item to a <List> with the Data key name from a gridview how would I go about doing it? example.
List<myClass> myList = new List<myClass>();
myList.add(new myClass(*//The value of the data key name that has been clicked*));
A user might click on another item so it would be repeated etc etc.
I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....
Using a gridView to read some data from a SQL database. The user can select a record in the gridview. On the SelectedIndexChanged property I populate this to a couple of text boxes & drop down list; txtCountry,ddlProvince,ddlCity.
I have special characters in France ( accent marks) and when I populate it to the drop down list it fails giving out the error message "SelectedValue which is invalid because it does not exist in the list of items".
Example of items that I try to populate are as follows. ( separated by commas) ÃŽLE-DE-FRANCE , PROVENCE-ALPES-CÔTE D'AZUR , RHÔNE-ALPES, DRÔME,ISÈRE ........ When I looked in the drop down lists for Province and Cities I see those Provinces there in the item list. When I debug line by line the word ÃŽLE-DE-FRANCE comes out like ÎLE-DE-FRANCE which is not there in the drop down list. Got to know the ÃŽ is typed by pressing down ALT+206 and lloks like this is what is coming in at the start of the string above.
This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

View 1 RepliesI have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.

I want to access a dropdown control value of each list item as soon as it is created. I tried with ItemCreated and ItemDataBound events but I am getting null contro when I try to access control as shown below:
ListViewDataItem item = (ListViewDataItem)e.Item;
int LstIndex = item.DataItemIndex;
RadComboBox ddlCategory = (RadComboBox)(listView1.Items[LstIndex].FindControl("rdComboCategory"));
Also, I get listview.item.count zero. IS there any event where I will get listitem count and list items?
