Hello ... I'm using a DatePicker along with a ProgressBar. In the ProgressBar1_RunTask I am calling a method to get the SelectedDate from the DatePicker .... no matter what date I choose I'm getting "01/01/0001" back.

Following is code snippet:

<eo:DatePicker runat="server" ID="fromDate" PickerFormat="MM/dd/yyyy" TitleRightArrowImageUrl="00040102" TitleLeftArrowImageUrl="00040101" TabIndex="2"
DayHeaderFormat="Short" DayCellWidth="22" DayCellHeight="16"
MonthSelectorVisible="True" WeekSelectorVisible="True" TitleLeftArrowDownImageUrl="00040103"
TitleRightArrowDownImageUrl="00040104" Width="100px">
<SelectedDayStyle CssText="background-image:url('00040105');color:white;"></SelectedDayStyle>
<TodayStyle CssText="background-image:url('00040106');"></TodayStyle>
<DisabledDayStyle CssText="COLOR: gray"></DisabledDayStyle>
<TitleStyle CssText="PADDING-RIGHT: 3px; PADDING-LEFT: 3px; FONT-WEIGHT: bold; FONT-SIZE: 8pt; PADDING-BOTTOM: 3px; COLOR: white; PADDING-TOP: 3px; FONT-FAMILY: Tahoma; BACKGROUND-COLOR: #0054e3"></TitleStyle>
<CalendarStyle CssText="border-bottom-color:Black;border-bottom-style:solid;border-bottom-width:1px;border-left-color:Black;border-left-style:solid;border-left-width:1px;border-right-color:Black;border-right-style:solid;border-right-width:1px;border-top-color:Black;border-top-style:solid;border-top-width:1px;padding-bottom:5px;padding-left:5px;padding-right:5px;padding-top:5px;background-color:white"></CalendarStyle>
<DayHoverStyle CssText="text-decoration:underline"></DayHoverStyle>
<MonthStyle CssText="FONT-SIZE: 8pt; MARGIN: 0px 4px; FONT-FAMILY: Tahoma; cursor:hand"></MonthStyle>
<FooterTemplate>
<div style="FONT-WEIGHT: bold; FONT-SIZE: 11px; FONT-FAMILY: Tahoma"">
<img src="{img:00040106}"> Today: {var:today:MM/dd/yyyy}
</div>
</FooterTemplate>
<DayStyle CssText="text-decoration:none"></DayStyle>
<DayHeaderStyle CssText="FONT-SIZE: 11px; COLOR: #0054e3; BORDER-BOTTOM: black 1px solid; FONT-FAMILY: Tahoma"></DayHeaderStyle>
</eo:DatePicker>

Code behind:

protected void ProgressBar1_RunTask(object sender, EO.Web.ProgressTaskEventArgs e)
{
doStuff();
.
.
.
.
}

/* during debug hovering over fromData.SelectedDate gives me 01/01/0001 */
protected void doStuff()
{
string startDate = formatDate(fromDate.SelectedDate.ToShortDateString());
.
.
.
}

Any help would be great ..... thanks ....

Hi,

ProgressBar will only post back simple form values. In order to get the DatePicker value, you must trigger the progress bar with script and copy the date picker value into a hidden field before triggering the progress bar. It will be something like this:

Code: HTML/ASPX

Copy

<!-- This hidden field is used to transfer date picker value  -->
<asp:HiddenField runat="server" ID="hiddenField1" />

<!-- This link is used to trigger the progress bar. 
The progress bar's StartButton is NOT set -->
<a href="javascript:start_task()">Start Task</a>

Code: JavaScript

Copy

function start_task()
{
    //Copy DatePicker value into hiddenField1
    var selectedDate = eo_GetObject("DatePicker1").getSelectedDate();
    var hiddenField = 
        document.getElementById("&lt;%=hiddenField1.ClientID%&gt;");
    hiddenField.value = eo_DateToString(selectedDate);

    //Start progress bar
    eo_GetObject("ProgressBar1").startTask();
}

Code: C#

Copy

protected void ProgressBar1_RunTask(
    object sender, EO.Web.ProgressTaskEventArgs e)
{
    //Get the value from the hidden field
    DateTime selectedDate = 
        EO.Web.Calendar.StringToDate(hiddenField1.Value);

    ....
}

Hope this helps.

Thanks

Duane
