Web Forms :: Use The DataTextField For A Label Control?
Aug 5, 2010<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

C# - Wrap ASP Control With Double Quotes
Jun 23, 2010I'm working in a Repeater over blog posts and I'm displaying a ShareThis JavaScript piece at the bottom. The Title and URL of the post are being sent to JS. In one test case, the title of a post has a single quote, e.g. Mark's test post Since I need to preserve that single quote when being sent to ShareThis, I need to wrap that JavaScript string in double quotes, however the string is being bound via a Literal and I cannot wrap the literal in double quotes: This is want I want but DOES NOT WORK:
SHARETHIS.addEntry({ title: "<asp:Literal ID="ltlTitle" runat="server" />", etc..
I can only wrap the literal with single quotes like so:
SHARETHIS.addEntry({ title: '<asp:Literal ID="ltlTitle" runat="server" />', etc..
But that will result in bad front-end code:
SHARETHIS.addEntry({ title: 'Mark's test post', etc..
How can I encode this correctly or somehow wrap the control in double quotes? I'm aware of HttpUtility.HtmlEncode and Server.HtmlEncode

Web Forms :: Dropdownlist DataBind Using Strongly Typed Property For DataTextField?
Aug 13, 2010I 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;

a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.
