how to populate datagrid based on dropdownlist changing
there is a radio button, a dropdownlist. radiobuttons are OY, OTY,VDA ( in my database there are fields named OY.OTY,VDA) if i select OY in my radio button the data should be displayed from field OY in dropdownlist and if i select OTY in my radio button the data should be displayed from OTY field in dropdownlist is it possible. there is a sqldatasource for dropdownlist .
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:MS16ConnectionString %>"
SelectCommand="SELECT DISTINCT OY FROM COURSE_INTAKE">
</asp:SqlDataSource>
THE SELECTED DROPDOWNLIST DATA IS REQUIRDE TO BE DISPLYED IN A GRIDVIEW.
So I have a dropdownlist and I'm trying to populate it with values in the database. For some reason, half of the rows has no value. It's happenning in a sequence as well, like the first row has no value, then the second row has value, then the third hasno value....
Does any one know why it does this?

I need to bind my dropdownlist to my dataset that is returning application specific text values. But for purposes on that page, i need to assign the value to each one starting at 0 to the number of items returned from my dataset..
Example, if my dataset only returns 1 item, the value of that item needs to be 0
[Code]....
If my dataset returns 4 items, the value of those items needs to be 0 thru 3
[Code]....
Is it possible to assign values like that to a dropdownlist from the code behind?
I'm running into a minor issue with some ASP.Net code I'm working on. For simplicity sake lets say I have two dropdownlists, one that is full of various items and another that is full of other items, but based off the selected item of the first dropdownlist. I currently set variables into hidden inputs to check to see if the item in the first dropdownlist has changed and if it has to change the second dropdownlist, but I'm also having to check to make sure that if something else causes a postback to NOT repopulate the second dropdownlist as to not lose what is currently selected by the user. This check also allows me to make sure that when I navigate away from the page, the correct values are selected and not something replaced by a postback repopulation.
I'm new to ASP.Net/HTML/CSS/Javascript and the like. I know while what I have works, it isn't even close to being the correct way to do things. correct my ways and figure out the BEST way to solve this current problem. Some good ASP.Net tutorial websites would be nice too as I need to keep improving my skills with it.

I'm tring to populate a datagrid using a stored procedure that returns about 20 fields (this part I figured out), but the kicker here is that for this one particular page I only want to display about 6 of those 20 returned fields.
I did find on passing the procedure the parameters that are required, and populating the datagrid, but haven't found anything (not that I can tell) that explains how to only view certain fields that have been returned.
I'm using VS 2008 and VB for my coding against a MS SQL 2008 server. All of the stored procedures are working with current windows applications.

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.
So far my edit page has a datagrid with the following code:

I'm trying to populate a datasource for a dropdownlist (which is actually in an insertitem template field within a detailsview on the same page) with a selectedvalue from a gridview. When I select a row in my Gridview 1, I get the "no value for a required parameter" message. ( and I have tried various alternatives... setting the selectedvalue of the grid to a variable... setting the selected value of the grid to a textbox nothing seems to work. It seems like this should be a pretty simple thing. I think I'm missing something obvious! Here is my code:
Field in Details view to be populated by the datasource:

I m trying to populate a set of 3 textboxes based on a value entered into the first textbox. So when a user enters a value in the first textbox, i would like them to be able to tab out of it and it will automatically populate the remaining textboxes.
I know javascript has the OnBlur function which can do this but is there a way to accomplish this using asp.net (c#)
just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.net
we usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds
dataGrid.DataBind()
What if if I want to edit or evaluate the data inside the DataSet?
In my webform I have a datalist that displays images that are approximately 200px each. The datalist is set to RepeatColumns = 5, RepeatDirection = Horizontal (display 5 images per row). With the padding and spacing, each datalist row takes up about 1200px in width.
The problem is that if a user with a 1024x768 or 800x600 resolution visits the page, he'll see the horizontal scrollbars. It's not really a problem, but, well...
Is there any way I can call a javascript function in page_load that will get the screen dimensions, and send that javascript result to my serverside so that I can change Datalist.RepeatColumns?
My javascript function would probably use screen.width and screen.height, but how do I send those values to my codebehind?
I have a quick question on my ddl. I have a search page that searches based on the ddl. Once the button is clicked. the result of the search shows on the gridview.Which all works well.Now the problem i am having is that. On my gridview i have a select button that brings out another ddl on an update panel based on the first ddl. When i do this... it goes back to the first record on the ddl and shows a wrong result.. Basically the new ddl is supposed to change on "selectedindexchanged" handler of that gridview which works fine but the selectedvalue is just going back to the first one.
View 11 RepliesI have written a code that populates data from database into the tree using C# and is working perfectly , the thing is how can i populate the tree based on a selection from a drop down menu
the code to populate the tree is below :
[code]....
1) 1 dropdownlist - department
2)Search button
3) 1 listbox that will display all the staff according to the selection of its department
So when i select the department and click search button, the listbox will be populated with the staff names.
I am trying to populate a dropdownlist with the current date (Month and Year only) and also the previous 9 months and year. I need it to change when a new month starts to always be the current and previous 9. Cant get my head round it.
View 2 RepliesI've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table.
example record from Cons Table: Serial number VendorID
508585 1
so when 508585 is selected in the dropdownlist, it would populate VendorID with 1 (this is my issue)once this happens, the user would fill in the other fields (hours, issue, repairco (also a dropdownlist linked to RepairCos table), RA Number, DCI, DPU, DRB, Cost, Record (which is a identity field and primary key for table) and when the insert link is pressed will insert all 11 fields as a new row in the ConsRepairHistory table. so the new record in the ConsRepairHistory table would look like:
Serial Number VendorID Hours Issue RepairCoID RA Number DCI DPU DRB Cost Record
508585 1 2250 alarming 2 20222 11/16/2010 11/17/2010 null null 3
the RA Number, DCI, DPU, DRB, Cost all allow null values.
