SqlDataAdapter adapSel;

Forms Data Controls :: DropDownList Control In A LoginView Control?

Nov 15, 2010

I've put a DropDownList control within a LoginView control. I've got 2 SqlDataSource controls outside of the LoginView control, with the intent of databinding the items that comprise the ListItems of the DropDownList control, and another one for the data is stored in another table which has what was previously saved for the selection. However, when I've assign the SqlDataSource control to the DropDownList control's DataSourceID for the lookup table, I'm used to seeing the fields from the SqlDataSource control appearing in the DataTextField and DataValueField properties. However, they're not appearing there at all. Moreover, even when I try to type them in, its as if VS 2010 refuses to allow them.

Forms Data Controls :: Bind A Dropdownlist Which Is Present Only In The EditItemTemplate

Jun 15, 2010

I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.

So it is throwing:

DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;
UIControlHelper.BindApprovalPeriod(ddlAccountingPeriod);

this throws a null exception as the dropdown is not present in the ItemTemplate.

Is there a way to check whether it is itemtemplate or edititemtemplate.

Forms Data Controls :: How To Put Tooltip In Dropdownlist Bind With Sqldatasource

Mar 4, 2010

I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,

item.Attributes.Add("title", someotherdatabasefield);

The end result would be something like this where the text for 'title' comes from the database

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

Forms Data Controls :: How To Bind A DropDownList Inside A Repeater

Oct 29, 2010

I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.

I also read this article [URL] but still can't understand how to bind dropdown in a repeater.

I want to display 2 things inside the Repeater Control.

1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.

2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)

Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.

Here is my code so far ....

ASPX Code:

<body>
