DropDownCheckBoxes: Using control

In this post I'll give more details about the DropDownCheckBoxes control.
After you've referenced the assembly and registered the control within application you may add its' markup to .aspx pages (see introduction post about how to add the control to the project).

From development point of view programming the control is no way different from using standard CheckBoxList control. It has same events (in fact only one is of interest - OnSelectedIndexChanged) and members (except those relevant to new rendering and client side behavior).

Example to start with

Let's have a look at an example and comment it. Bellow is a markup snippet from .aspx file:

...
<asp:DropDownCheckBoxes ID="yearsDropDownCheckBoxes" runat="server"
OnSelectedIndexChanged="checkBoxes_SelcetedIndexChanged"
AddJQueryReference="True" UseButtons="True" UseSelectAllNode="True">
<Style SelectBoxWidth="160" DropDownBoxBoxWidth="160" DropDownBoxBoxHeight="80" />
<Texts SelectBoxCaption="Year" />
</asp:DropDownCheckBoxes>
...
<div style="padding-top: 20px;">
<h1>
Selected items (updated whenever postback from any of the controls occurs)
</h1>
<asp:Panel ID="selectedItemsPanel" runat="server">
</asp:Panel>
</div>

Code snippet from the corresponding code-behind file:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
var years = new int[20];
var currentYear = DateTime.Now.Year;

for (int i = 0; i < years.Length; i++)
years[i] = currentYear--;

yearsDropDownCheckBoxes.DataSource = years;
yearsDropDownCheckBoxes.DataBind();
}
}

protected void checkBoxes_SelcetedIndexChanged(object sender, EventArgs e)
{
selectedItemsPanel.Controls.Clear();

foreach (ListItem item in (sender as ListControl).Items)
{
if (item.Selected)
selectedItemsPanel.Controls.Add(
new Literal()
{ Text = item.Text + " : " + item.Value + newLineConst } // HTML line break
);
}
}

The page contains a drop down check boxes for selecting years and a panel bellow which displays checked items whenever a postback from the control occurs (code for other controls from the picture was cut above):


From the example we see that a control yearsDropDownCheckBoxes is added to a page, the event handler checkBoxes_SelcetedIndexChanged for SelcetedIndexChanged event is assigned and the page load handler performs data binding for the control. Whenever a user clicks 'OK' button in the drop down list a postback goes to server and panel in the bottom of the page is filled with all checked items. Everything is straightforward and no different from using controls inherited from ListControl(including CheckBoxList).

Postback options & behavior

Properties DropDownCheckBoxes.AutoPostBack (default value is 'false') and DropDownCheckBoxes.UseButtons (default value is 'true') control the way postbacks from the control arise:

1. AutoPostBack == false && UseButtons == false - in this case no 'OK/Cancel' buttons are displayed in the bottom of the drop down box, no postback occurs when a user clicks outside control and drop down gets hidden. The server side event will be fired (if there's a handler specified) during postback from any other control from the page (in case selection change is detected). The behavior in this case is similar to other ASP.NET controls with AutoPostBack set to false;

2. AutoPostBack == true && UseButtons == false - no action buttons ( 'OK/Cancel' ) are displayed, postback occurs whenever a user leaves the expanded drop down by clicking outside it.

3. UseButtons == true (AutoPostBack value doesn't matter) - in this case there're action buttons displayed in the bottom of the drop down box. Postback is triggered only when a user clicks 'OK' button. Clicking 'Cancel' or outside the control collapses the drop down and restores the check box selection prior to opening the control.

JQuery dependency

JQuery library is delivered within the control assembly and the reference to it is automatically added to the page by the control. In case you have JQuery referenced on the page (e.g. in a master page) script errors may occur.

In order to turn off automatic reference adding set DropDownCheckBoxes.AddJQueryReference to 'false'.

Other control properties

  • DropDownCheckBoxes.UseSelectAllNode - if 'true' then there's a 'Select all' check box added on top of other check boxes in the drop down. Clicking the check box changes all other check boxes' to corresponding state.
  • DropDownCheckBoxes.Texts - a complex property that allow to change default texts of the control elements (caption, button names, 'Select all' check box), e.g. for localization.
  • DropDownCheckBoxes.CssClass - specifies CSS class name applied to the control (specifically the DIV element which wraps all the contents). Setting this peoperty has the same effect as using DropDownCheckBoxes.Style.SelectBoxCssClass property.
  • DropDownCheckBoxes.Style - a complex property that allows applying CSS classes to the control and also directly specify sizes of the control elements (height of the select box, width and height of drop down box).

NOTE: The control can work within update panel without any adjustments.

  1. hi there. i got a problem using this control.

    as soon as i add the

    Style DropDownBoxBoxWidth="100"

    part in the control's html


    i get a parser error with the error message "Ambigious match found"

    i have no clue how this happens but it even happened when i started a clean web application.

    1. I dont know if you sorted it out or not.. but i figured this can be solved by using code behind:

      dropdownbox.DropDownBoxBoxWidth=100

      Delete
    2. Please use <Style2 DropDownBoxBoxHeight="130" DropDownBoxBoxWidth="200" in your Code.

  10. I have also tried clearing all the items from the list and rebinding it and I still get the same items selected. Could it be a view state problem?

  11. are you using a objectdatasource to fill the dropdown?

    ReplyDelete
  12. disable the sqldatasource (dont set the DataSourceID of the dropdown) and then try clearing the dropdown's items,(i might be wrong but) the sqldatasource refreshes the dropdowns items (checking them again) after a each postback is done
    i think that is whats screwing up your code

  17. Dear, First of all thanks, this is the only control so far working properly inside a gridview, which is wonderful, without any issues. Anyways, i have another request, is it possible to extent this control and add a textbox against each checkboxlist item, i have a complex scenario where the user will select each Item and against that item he has to give a value, so can you please help me or explain me, how to extent this model to include a textbox, either using server side control like textbox or client side using Jquery or javascript. I hope to hear back soon from you.

  24. Hi,

    Please paste the following code in DropDownScript.js file and make Autopostback= false for the dropdown.

    Then call the below function inside the checkBoxClickHandler.


    DropDownScript.prototype.updateText = function () {
    var text = '';
    $( "#" + this.id + " input:checked" ).each( function()
    {
    if (text == '')
    text = $(this).next('label').text() ;
    else
    text = text + ', ' + $(this).next('label').text() ;
    });
    if(text == '')
    $("#" + this.selId).find($("div[id^='caption']")).html('Select');
    else
    $("#" + this.selId).find($("div[id^='caption']")).html(text);
    }

  26. Is there a way to only do a post back when selections have changed? Right now a post back occurs when you leave and click outside the drop down (as described above in AutoPostBack == true && UseButtons == false section). But, it would be nice to have it only post back when a change was made.

    Thanks in advance.

  72. I'm using this control for several fields on my form. Some are loaded with data on the initial page load, and others on a partial PostBack when a GridView item is clicked. This is a must as the values in the control change based on the record being edited. The controls loaded on the initial page load post selected values as expected. The instances that are loaded on a partial page PostBack always indicate no items are selected. I am able to programmatically select the items associated with the editing record after binding to a DataTable stored in ViewState, but I can't get the values when updating the record. All controls are in UpdatePanels so I know that isn't the issue.

    I think I've run into this issue with other controls and resorted to using hidden fields populated client side before posting back. However, I haven't been able to get the values for this control on the client. It appears values aren't even being stored even though I bind to a DataValueField. I can't use the innerText due to the complexity of mapping to an id. How can I get the values client side?

  105. Hi,

    I am using DropDownCheckBox control on the top to filter some info inside GridView.. When i click on Edit / Update it is working fine for the first time. But when i click on second time on Edit it is keep loading.

    Without DropDownCheckBox ( when i set to Visible = Flase) then the page is loading well without issues. Please advice.



    Thanks
    Ravi

  112. Hi,
    This is really a nice blog by you. I really appreciate your efforts for this blog. Keep it up and keep posting such blogs.
    There is one language which is most commonly used and that everyone knows after their mother tongue is English. English is one of the most spoken languages in the world. But it is seen that most of the people hesitate to speak English fluently as they didn’t get the necessary environment to learn english. This is because most of the people take online spoken english classes to learn to speak English.
