Mar 13, 2011
I want to populate a dropdownlist from content from a datbase. But strugling to get the dropdown list to populate. the value is a primary key and the text value is a name associated with the id.
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.
I have 2 dropdownlist, one is to dropdown department, and another dropdown staffnames. the secong dropdownlist will based on the selection of department as each department has different staffs i have 2 tables department and staff in my database , in my department table i have departmentid as PK and departmentname, in my staff table i have staffname and departmentid as FK. So my ques is how am i going to populate staffname in the dropdownlist according to the selection of department.
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.
I'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.
When someone selects one of the search criteria, I want the other dropdownlist boxes to re-populate with only the information from the current search and take out all other information if that makes sense. This search functionality works except it the dropdownlist boxes stay populated with all information originally loaded from the database. Here is my code:
I am using 3 dropdown list in a gridview and the values for the dropdownlist is dynamic from database.based on first dropdown list selected value the values must fill to second dropdown and based on second dropdownlist selected value then items should load to 3rd dropdown and same for 4th dropdown list. Here if i select age,gender,sex, fist name, last name from the template name Human. The first drop down only populate the fields like Age,gender,Sex and so on., When the second dropdown list populate from the fields corresponding Template name Human, Finance, and so on.
I want to create this scenario: The user selects a school from ddlSchool and this populates ddlStaff with a list of staffs in that school. i knw the codes for sql database but dont know how to do it for oracle.
populating the dropdownlist with column name. I have a gridview that has 7 columns . I want to have a textbox search and dropdownfield where user can select column name and type a word in search box and click search so that text for that column name is being search and displayed in grid. how I can fetch just column names from DB and search ?
Scenario is: I have multiple positions and multiple employees.
Now in one of my forms I know how many positions are there and corresponding to each position i want to show Employee DropDownList(DDL) and Text Boxes (Start Time, EndTime) and some comments for each position. Employee DDL will be populated from DB and Position name will be displayed on labels and that too are getting form DB
say at one instance i have 5 positions and then i want DDL of EmployeeName for each position and similarly TextBoxes for each positions Where i can ask user to full the information for each Position and user can save the data.
And at another instance similar behaviour is required if Positions are 10 , 3 , 8.
I am trying to develop a simple MVC 2 timesheet application for my small business. I have a sort of mock model for now until I have a database in place, just to make things simpler while I develop the functionality.
[Code]....
But then I need to populate a second dropdownlist (taskDropDownList for the tasks associated with a particular customer) based on the selection the user chooses in the customer dropdownlist. But how do I do this exactly? I have seen examples with jQuery, but I'm not sure how to apply them to this situation. Also, the examples seem to just populate the lists with string values. I need to be able to access the objects with all their properties. Because the next thing I need to do is to be able to populate the TimeSegments list of the selected task with values from input fields (i.e. the hours worked for particular dates). And for that to be saved to the "model" (eventually to the database) in the controller, how do I get it there, unless the objects are all part of the same model bound to the View? I'm on rather thin ice with this since I still find the connection between the View and the Controller hard to handle, compared with e.g. Windows development, where these things are rather easy to do.
I am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.
I have a ddl inside the formview that I can't figure out how to wire up properly. The formview contains detail info, but the ddl needs to list the entire set to items. Then I want the ddl's selected value be set from the recordset intended for the formview. I think it's just a timeing issue s I would like your help. Thanks, - EJM.
I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.
I have a dynamically generated dropdownlist, that lists e.g. Company Names. I want to be able to select a particular Company and display associated information e.g. Name, Address, City, State... etc. in text boxes adjacent to the list.
I am trying to fire the following code from the dropdownlist "OnSelectedIndexChanged" property, but cannot 1) get the code to fire upon selection, and 2) populate the text boxes...
