Move DataTextField & DataValueField From Listbox1 To Listbox2?
Jul 9, 2010
I have 2 listboxes....
Listbox1 has
DataTextField="Category"
DataValueField="CategoryID"
(coming from Dropdownlist)
I want to move a Item (a Category) from listbox1 to listbox2...but how do I move this Category Plus the CategoryID to lisbox2 (CategoryID should not be visible but still be associated with Category in Listbox2)
So I want the newly added Categories to be visible in Listbox2 ..but their CategoryID's must be invisible...but still be associated with their Category....
and when I save these Categories from Listbox2 to the Database.....its should be the CategoryID's that should go into the Database.....not the actual Category
So to explain again in a different way
I want to Move a selected DataTextField & its DataValueField from Listbox1 to listbox2
then only the array of DataValueField must be saved to Database
i want to know how to copy multiple items from Listbox1 to Listbox2.i tried in single item copy it's working but i want to know multiple items to copy.
I am trying to find out if there is an easier way to insert datavaluefield and datatextfied in a DDL.... I have two dropdownlist...the second ddl prepouplates based on the first one. All works now cos i have all my datavaluefield inserted. Now i was woundering if there is a way to caputure the datatextfied too so users can see it instead of seeing the ID alone. here is my code
I'm currently working with a control that inherits from DropDownList (it has some extra functionality that isn't really relevant to this question, but it gives me a nice place to implement the extra stuff I'm gonig to discuss).
We're using data binding, with the DataTextField and DataValueField working absolutely fine. However, I find myself in need of a similar field that will control whether or not the item is enabled. (I've already overridden the RenderContents method of the control so it properly renders non-Enabled items, since DropDownList doesn't do this by default.)
Thus I'd like to know how to override the DropDownList's data binding so it acts exactly as normal, except a further field from each DataSource item is applied to each ListItem's Enabled property.
(NB: the field I'll be binding to isn't a straight boolean, and doesn't have an explicit/implicit cast to boolean, so I'll probably be "passing" it as a string.)
I have used a webservice to populate a Rad Combo Box, when the page is loaded, I need the ability to display the DataTextField, based on the returned DataValueField item
I have a dropdownlist for which I am loading data from excel. Excel has 2 columns Product and Email. Data in Product column is binding to DataTextField and Email column to DataValueField. The dropdown works fine when email is different for different product but when email has same value for different product then whatever I select, on postback the selected value changes to the first item of the same email value.
Below are the sample data in Excel to show the behavior of dropdown
Example 1. (Drop down works fine for this example)
Example 3. (In the example below, when I select iPad the dropdown works fine but when I select iPhone 3G or iPhone4 on post back the dropdown selected value will be iPhone 3G. Basically, on selecting iPhone4 here, on post back it shows iPhone 3G)
I have a list <Department> say Company.Departments with object Manager and ManagerId, ManagerName as property of Manager. I would like to fill the dropdownlist with managers as below
I have 2 ListBoxes..ie ListBox1 and ListBox2.When Move items from ListBox1 to ListBox2,I want to save listBox2 values in Xml Files.When i open the page it will load lListBox2 values.
i want to get data from database of field Name and Gender, and then display it in Label name and gender. when i click save it move to next record and display name and gender that next record.
I have 3 update panels on a page, each of them have UpdateMode="Conditional".
UpdatePanel1 contains listbox1 (AutoPostBack set to true) which is populated on pageinit from the DB.
UpdatePanel2 contains listbox2 (AutoPostBack set to true), this panel has AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox1 in UpdatePanel1.
UpdatePanel3 contains textboxes that will hold the details once an item has been selected from listbox1 and listbox2, this panel has an AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox2 in UpdatePanel2.
In the codebehind, the SelectedIndexChanged event for listbox1 populates listbox2 and the SelectedIndexChanged event for listbox2 populates the textboxes in UpdatePanel3.
The problem
When the page loads listbox1 is correctly populated, I select a value from listbox1 and listbox2 is populated, great, no problem so far. When I then select a value from listbox2 the SelectedIndexChanged event for listbox1 is firing, I assume that as this populates listbox2 again it is clearing the selected value for listbox2 as the SelectedIndexChanged event for listbox2 is not firing.
How do I stop the SelectedIndexChanged event for listbox1 in UpdatePanel1 from firing when I select a value from listbox2 in UpdatePanel2 ?
We have an already existing project on IIS and we want to move to Apache (windows) with mod_aspdotnet. What things could not work? If we use 3rd party DLLs? Will office components work fine (export to Excel, Word, etc). If you have any experience on this type of migration, I'd like your inputs! Also, is there another alternative to mod_aspdotnet?
I'm using radcombobox and radgrid.Here i want to display ward_no but store ward_id in database.But in my code ward_id field not store, ward_no is store. What is the problem?
I'm retrieving the data from database to fill the combobox. The name of the combobox is kategorilist. I want to set a string value to datavaluefield of the combobox. Also I'm using datalist with paging in this page. Datalist is binding with the selected value of the combox everytime.
What do I use to set the dataValueField of the Select List when I'm using a list of strings. I want to be able to set the value of the option in the select. If i have:
List<string> list = new List<string>(); list.Add("apple"); list.Add("orange");
I have a dataset which I am binding to a listbox. However, I want to combine two of the fields to make up the DataTextField. Is this possible, or am I going to have to loop through the Data Rows?
Is there a way to display several records in the datatextfield in a asp dropdownlist? I know the fix when populating the dropdownlist from a datagrid was to edit your SQL query but the values I am receiving are sent via an XML string. The idea would be to display a name, price, and date in the dropdown text. Currently I am getting the following error: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'MonetaryValueServiceType' While using UPSDropDown.DataTextField = "MonetaryValue" & "ServiceType" Is there a work around to do this? The only other option is to use radio buttons (which are also a nightmare).
<asp:SqlDataSource ID="sql_Region" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" SelectCommand="SELECT Number, Name FROM table_Region WHERE Number = @Number" SelectCommandType="Text">
<asp:DropDownList ID="dd_Region" runat="server" DataSourceID="sql_Region" DataTextField="Name" DataValueField="Number" /> Ok, I have this dropdownlist and I want to use the DataTextField for a label control.
Something like this. I want to show the region as a label but I only could get the DataValueField value not DataTextField value. Does anybody knows? <asp:Label ID="label_Region" runat="server" /> <C#>
label_Region.Text = dd_Region.SelectedValue.ToString(); <--I know by doing this, I can get the DataValueField but. label_Region.Text = (DataTextField) <<--How do I get this value? I want to show the region name not the region number
