Oct 5, 2012
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">
THE SELECTED DROPDOWNLIST DATA IS REQUIRDE TO BE DISPLYED IN A GRIDVIEW.
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 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
If my dataset returns 4 items, the value of those items needs to be 0 thru 3
Is it possible to assign values like that to a dropdownlist from the code behind?
I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:

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 Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
I am trying to populate (bind with a dataset) a DropDownList inside a GridView. However, when I do my DropDownList.DataSource = dataSet.. I get the following exception ( Object reference not set to an instance of an object. )
Here is my GridView in the .aspx page:
Here is the code behind...
Private Sub gvTransferNumbersEN_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvTransferNumbersEN.RowDataBound
If (e.Row.RowType = DataControlRowType.DataRow) Then Dim dsGetTransferNumbers As DataSet Dim ddlTransferNumbers As DropDownList = DirectCast(e.Row.FindControl("ddlTransferNumbers"), DropDownList)
Suppose I have a e-shop web app. I have a product categories table in my database that populates a gridview using sqldatasource.
I want to be able to click on the select hyperlink on a row and use that event to populate ANOTHER gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
I want to filter grid view, drop down list should select the column and text box will filter the column. like ID NAME Phone Designation fields in gridview.i will select Designation in dropdown and type programmer in text box .so it should filter programmers from the gridview...
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.
