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:

Forms Data Controls :: Conditionally Bind Text Property Of DropDownList

I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.

Forms Data Controls :: Unable To Bind Data To DropDownList In DetailsView

Sep 15, 2010

I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.

The scenario:

DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.

Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.

when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.

The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.

My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".

I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.

code:

The SqlDataSource used to select the parameters from the table and populate the DetailsView

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

Nov 19, 2010

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).

ASPX CODE

[Code].... C#

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

Forms Data Controls :: DropDownList Bind Error - Force Order Of FormView And Child Controls Load?

May 4, 2010

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:

<asp:FormView
ID="fvTicketUpdate"
runat="server"

[code]...

The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:

public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)

[code]...

The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:

Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.

Forms Data Controls :: How To Add Lookup Table Values To A DropDownList And Bind To A FKValue In The Grid

Jan 26, 2011

I have a GridView control that has a SQLDataSource.

The GridView provides me with a list of musical artists (from the tblArtists)

In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.

(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)

What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.

Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList

Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.

Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.

My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.

Is this possible?

In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
