Web Forms :: Remove Duplicate Values From DropDownLists Populated From Database
Mar 18, 2013
Table1:
ID Â Â Â Â FROM Â Â Â Â Â TO
12 Â Â Â Â TXS Â Â Â Â Â Â NY
12 Â Â Â Â LS Â Â Â Â Â Â Â NY
This is my table ... I am retriving the values of "FROM"  and "TO"  based on the id .. Separate Dropdownlist for FROM & TO . While Displaying , in  "TO" Dropdownlist NY value is repeated twice .. How to remove the duplicate value? need vb coding frnz ...
I have hard coded and added items to dropdownlist ie teamsize as 1,2,3 like that.When i load this dropdownlist for edit/update i get duplicate values like this
I have a master table relationship, i.e. depending on what is selected in the dropdown list the grid show the relevant data.In the database there are several identical entries for the Position field, for instance there are four marketing managers that have different name. How can i group the identical Position name in the dropdown and when selected the grid should display all marketing managers. Here is the code:
I have a detailsview with template fields. when i go into edit mode i am trying to set the selectedvalue of a dropdownlist to be the value of the corresponding label from the item template in code behind as once i go into edit mode i loose the initial value from the detailsview and the dropdownlist defaults to the first listitem. what i am doing is onDataBinding of the detailsview i access the cell value of the label , i then assign that to a public variable but once i've exited the routine the public variable looses the value of the detailsview cell i've just assigned to it. this is the value i'm hoping to assign to the selectedvalue of the dropdownlist when i go into editmode. The reason i'm doing it this way is although i can use bind in the html to mantain the dropdownlist selected value between detailsview states once i come to update the detailview i get the following error
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.to work arround this i've had to assign the values to update paramteres also in code behind. here's my code behind page i've bolded the routines in question. drpDataStoreDDL is the variable in question.
I have a FormView in InsertItem that contains one DropDownList linked to a Table Datasource to display ItemCodes. In that "lookup" table I also have a Retail and Cost field.When the user selects the item from the drop down, how can I have these to field carry over into my new record that is being inserted. The new record also has a Retail and Cost field that are TextBoxes.Basically I am populating the new fields with the default values from the DropDownList.
I have 2 divs with 2 nested divs in them. Let's say div1 contains div11 and div12 and div2 can also contain div11 and div12. I know that this is not normally allowed but I am using jTemplates and they do allow you to print the div11 and div12 twice or more on the same page. The HTML looks like this:
How do I ensure that I only have one div with the unique ID loaded on the page, so I don't get in any duplicate DIVs. The result should look like this:
<DIV1> <DIV11>Some text</DIV11> <DIV12>Some text</DIV12> </DIV1> <DIV2> Some other text </DIV2>
Is there any way to check for a duplicate ID in either jQuery/javascript language and remove all but one using each or some other method?
I have a linq statement that retrieves several rows from a stored procedure and maps them to a custom class. The rows returned could contain mulitple instances of the same ID
eg id date total 1 01/01/2011 3 2 01/02/2011 2 3 02/03/2011 5 1 01/01/2011 3
the stored procedure perfoms some complex calculations to return the data How can I remove the duplicate rows in the list ive returned? Ive tried distinct but it doesnt work I want to process the RETURNED list (as there are only 4 rows here, i want to end up with 3) and just have 1 instance of ID 1.
I have a form with 2 sections. The first one contains some radio buttons. The second one contains a checkboxlist. When we change the selected radio button then it modifies the elements in the checkboxlist. For this I setted the radio buttons with autopostback, and in the code behind (in OnLoad) I populate the CheckBoxList depending on the selected radio button.
This work fine.
The problem is that I also have a button at the end of my form which post the data of my form in another page (with PostBackUrl). Then in that page I would like to retrieve the values of the checked checkbox. But I can't find how to do that. In the Request.Form I don't see anything.
I searched on the web but I didn't found really a solution.
m using a listview and an object data source in my application, with optimistic concurrency control.i have only 2 columns in the listview: category_ID and category_name;when i try to delete an item, an error message is generated saying that one of the old values populated by the list view is null, i performed debugging, and found that the category_ID old value is populated correctly, while the category_name old value is populated as nulli can't find a problem in the code, i executed the delete command in the query builder directly and it worked fine,
removing duplicate rows from datatable or (dataset) by columnd ID (unique). Below function is working but I would like to edit/adjust the remaing (former) duplicate row's value, not the ID value btw.
Example:
ID name sport ------------------------------- 356 John Football 357 Johny Hockey 357 Johny Hockey 358 mike Soccer
should be:
ID name sport -------------------------------------------------------------- 356 John Football 357 Johny newFoo Hockey 358 mike Soccer
Public Function RemoveDuplicateRows(ByVal dTable As DataTable, ByVal colName As String) As DataTable
Dim hTable As New Hashtable() Dim duplicateList As New ArrayList() For Each drow__1 As DataRow In dTable.Rows If hTable.Contains(drow__1(colName)) Then duplicateList.Add(drow__1) Else hTable.Add(drow__1(colName), String.Empty) End If Next For Each dRow__2 As DataRow In duplicateList dTable.Rows.Remove(dRow__2) Next Return dTable End Function
i have a checklistbox that is databound during Page_Init in an
If (!Page.IsPostBack)
block. the user can then check off certain values, and click an asp.net button which posts back the form and renders a crystal report on the same page.
i need to be able to determine which items were checked in the control so that they can be used as parameters in the crystal report. rendering must be done during Page_Init.
the checklistbox object is on the page during design time; only the items are dynamic.
i tried using the Request.Form object during Page_Init to obtain the checkboxlist's items but either i didn't code it correctly or it can't be done that way...
can the checkboxlist items' values be obtained during Page_Init, and if so, how?
I'm trying to use two cascading dropdownlists with the same values -- one shows a code, and the other a description. They are sorted alphabetically, so they have the same values, but not the same index. Both are generating correctly. What I am trying to do is set the abbreviation when the description changes (and vice versa).If I use this javascript, it changes on the web page, but I get a null value returned to the form handler. If I comment out the CascadingDropDown control and load the TrickAbbrev from a database it all works.
I have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors
Imagine I'm developing a webform with two dropdownlists and a submit button. The second dropdownlist depends on the choice in the first, and both are loaded dynamically using webmethods being called with javascript in de ASPX page (ajax). When I submit the form to the server, to save the data, I can't get the value of those dropdownlists. I think it is because with client AJAX no viewstate data is being generated. I need to send the data to the server and save the webform data, and identify wich data is on each webcontrol.
I have a web user control with a dropdown that is populated from a SQL table:
[Code]....and then the .cs
[Code]....
Catalog Access:
[Code]....
I can give the rest of the GenericDataAccess if that will help, but here's the problem; When I run a web page with this control, all the dropdown items are 'System.Data.DataRowView'I'm sure there's some obvious stuff I'm missing but I'm new to populating dropdowns.
We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...
