Display Several Records In The Datatextfield In Asp Dropdownlist?
Mar 27, 2010
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).
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.)
Public Class State Public Property StateId As Integer Public Property Name As Dictionary(Of Integer, String) End Class
Name(x) contains the state name in different languages. I get a collection of State from the method StateManager.GetAllStates() and I want to bind this collection to a DropDownList. The problem is that I can't find how to set the DataTextField property to let's say stateList.Name(1) which is the english name of my state.
Dim stateList As StateCollection = StateManager.GetAllStates() Me.DataSource = stateList Me.DataValueField = "StateId" Me.DataTextField = "Name(1).Value" <-- Problem here Me.DataBind()
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 dropdownlist which contains TEACHERS and STUDENTS, and I'm using gridview to show their information. But I don't know how to display records that depends in dropdownlist.
I would rather not magic string my DataTextField/Values on the dropdownlist after setting up the source as a List collection of objects.
I was thinking I could use the DataSource properties but it doesn't seem to like the couple of ways I tried.
WORKS BUT NOT IDEAL //set the datasource to the returned List<Cart> this.cartDdl.DataSource = CartManager.Load(WebProfile.Current.UserName); //set the DataValueField to the Cart.ID property this.cartDdl.DataValueField = "ID";//would rather use the obj property Cart.ID //set the DataTextField to the Cart.Description property this.cartDdl.DataTextField = "Description";//would rather use the obj property Cart.Description //Bind the ddl to the datasource this.cartDdl.DataBind(); HOW I WOULD THINK IT COULD WORK this.cartDdl.DataValueField = ((Cart)this.cartDdl.DataSourceObject).ID; this.cartDdl.DataTextField = ((Cart)this.cartDdl.DataSourceObject).Description;
I am working on displaying records in grid view. I have a dropdownlist on top of the grid and has items as 5 results per page, 10 results per page and 25 results per page. I would like to display only that many set of records per page as chosen from dropdownlist . I have tried this but don't see any change when i chose different options ..
<asp:DropDownList ID="ddlDisplayPerPage" runat="server" Height="22px" Width="155px" onselectedindexchanged="ddlDisplayPerPage_SelectedIndexChanged" AutoPostBack="True"> <asp:ListItem Value="5">5 Results Per Page</asp:ListItem> <asp:ListItem Value="10">10 Results per Page</asp:ListItem> <asp:ListItem Value="25">25 Results per Page</asp:ListItem> <asp:ListItem Value="50">50 Results per Page</asp:ListItem> </asp:DropDownList> protected void ddlDisplayPerPage_SelectedIndexChanged(object sender, EventArgs e)
I have a datagrid control which is bound to a table which containing more than 1000 records. And i want to show only 25 records once a time. I have used paging in datagrid. But each time the next page index is set, query is fired again. This takes lots of time. So what is the easiest way to bound data in this case to improve performance.

How to Show Records In a GridView Using DropDownList and that DropDownList is placed in GridView one row can be visible on page load after that on drop down selected index changed it will show another row in the grid vview.
I am trying to find out the best method or practice to use a dropdownlist to feed my oracleparameter value. I currently have this working when I have a value selected in the dropdownlist. My issue is how to account for if the user leaves the dropdownlist empty. I want this to then return all data. My SQL has a where clause = to :HRM. I use a function that gets the text for my SQL from a text file. My dropdownlist box is populated via databind. I then inserted a item in my dropdown with 0 index with no text display and a value of "novalue" Below is my code to populate my dropdownlist
[Code]....
[Code]....
If I select an item and run my code it works great. This doesnt work with the no selection tho. Do I have to build the SQL dynamically with a check if the listbox is empty or not and then add the criteria? I was hoping there was a eailer way since I have many queries and parameters to build.
Here is part of my code using the oracleparameter.
[Code]....
I also saw a post about trying this, but I get an illegal error.
[Code]....
Not sure if I can replace the "AND HRM_FIELD = " text and use :HRM instead and then build the oracleparameter with an IIF to include the AND HRM_FIELD part.
