DatePicker Value not correct after postback

[Evan Hang]

Hi:

When i select the DatePick i got the correct date, but when page postback, the value always show the default value.

  <td style="width: 139px">

                    <ej:DatePicker runat="server" ID="datePicker" ClientSideOnChange="onClick" EnablePersistence="true" ></ej:DatePicker>

</td>

On page i choose 2/18/2021. 

Then i choose a data in dropdownlist which postback the page.

But in Code Behind, the value shows: 3/12/2021 which is default value.

Hi Evan, 

 

Thanks for contacting Syncfusion support.  

 

We have checked the reported issue in our end with the provided details. We have rendered ejDatePicker with your code and retrieve this date value through OnSelectedIndexChanged event of ASP DropDown in code behind.  

 

Refer to the following code and screenshots. 

 

<h3>EJ1 DatePicker</h3> 

       <ej:DatePicker runat="server" ID="datePicker" EnablePersistence="true" ></ej:DatePicker> 

    <h3>ASP DropDownList</h3> 

    <asp:DropDownList ID="ddl1" runat="server" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true"> 

        <asp:ListItem Text="Item 1"></asp:ListItem> 

        <asp:ListItem Text="Item 2"></asp:ListItem> 

    </asp:DropDownList> 

 

Protected Sub ddl1_SelectedIndexChanged(sender As Object, e As EventArgs) 

        Dim dateValue As String = Me.datePicker.Value 

    End Sub 

 

The selected value is updated as shown below 

 

 

Code behind:
