How to fire radwindow OnTextChanged event

[Dorababu]

Hi all I am having my textbox designed as follows

<telerik:RadMaskedTextBox Mask="###-##-####" runat="server" ID="txtSSN" Width="200px" AutoPostBack="true" OnTextChanged="ssnchanged">
        </telerik:RadMaskedTextBox>

On my server side code I code as follows

protected void ssnchanged(object sender, EventArgs e)
   {
       if (txtSSN.Text.Length != 9)
       {
          RadWindowManager1.VisibleOnPageLoad = true;
           string scriptstring = "radalert('You must save Employee Information to proceed further..', 250, 80,'Information');";
           ScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", scriptstring, true);
       }
   }

But unable to load the Window can some one help me..

Hi,

Here is the sample code that works for me as expected. Please make sure that The RadTextBox is inside the UpdatePanel.

ASPX:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
</telerik:RadWindowManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
  <ContentTemplate>
    <telerik:RadMaskedTextBox Mask="###-##-####" runat="server" ID="txtSSN" Width="200px" AutoPostBack="true" ontextchanged="txtSSN_TextChanged" >
    </telerik:RadMaskedTextBox>
  </ContentTemplate>
</asp:UpdatePanel>

C#:

protected void txtSSN_TextChanged(object sender, EventArgs e)
    {
        if (txtSSN.Text.Length != 9)
        {
            RadWindowManager1.VisibleOnPageLoad = true;
            string scriptstring = "radalert('You must save Employee Information to proceed further..', 250, 80,'Information');";
            ScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", scriptstring, true);
        }
    }

Thanks,
Shinu.

Hi thanks for the code but validation is not firing when I have validations as follows

<asp:UpdatePanel ID="up" runat="server">
            <ContentTemplate>
                <asp:Label runat="server" ID="lblSSN" CssClass="label1" AssociatedControlID="txtSSN"
                    Width="150px">Social Security Number</asp:Label>
                <telerik:RadMaskedTextBox Mask="###-##-####" runat="server" ID="txtSSN" Width="200px"
                    AutoPostBack="true" OnTextChanged="ssnchanged" >
                </telerik:RadMaskedTextBox>

                <asp:RequiredFieldValidator Display="Dynamic"
                    ID="mskdrqrdSSN" runat="server" ErrorMessage="Please, enter SSN number." ForeColor="Red"
                    ControlToValidate="txtSSN">
                </asp:RequiredFieldValidator>
                <asp:RegularExpressionValidator Display="Dynamic" ID="mskdregvdSSN" runat="server"
                    ErrorMessage="Format is ###-##-####" ControlToValidate="txtSSN"
                    ForeColor="Red" ValidationExpression="^\d{3}-\d{2}-\d{4}$" />
            </ContentTemplate>
        </asp:UpdatePanel>

Hi Dorababu,

Here is the sample code that I tried based on your scenario and it is working as expected.

ASPX:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
   <ContentTemplate>
     <asp:Label runat="server" ID="lblSSN" CssClass="label1" AssociatedControlID="txtSSN"  Width="150px">Social Security Number</asp:Label>
     <telerik:RadMaskedTextBox Mask="###-##-####" runat="server" ID="txtSSN"  Width="200px" AutoPostBack="true" ontextchanged="txtSSN_TextChanged" >
     </telerik:RadMaskedTextBox>
     <asp:RequiredFieldValidator Display="Dynamic" ID="mskdrqrdSSN" runat="server" ErrorMessage="Please, enter SSN number." ForeColor="Red"  ControlToValidate="txtSSN">
     </asp:RequiredFieldValidator>
     <asp:RegularExpressionValidator Display="Dynamic" ID="mskdregvdSSN" runat="server" ErrorMessage="Format is ###-##-####" ControlToValidate="txtSSN"  ForeColor="Red" ValidationExpression="^\d{3}-\d{2}-\d{4}$" />
   </ContentTemplate>
</asp:UpdatePanel>

C#:

protected void txtSSN_TextChanged(object sender, EventArgs e)
    {
        if (txtSSN.Text.Length != 9)
        {
            RadWindowManager1.VisibleOnPageLoad = true;
            string scriptstring = "radalert('You must save Employee Information to proceed further..', 250, 80,'Information');";
            ScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", scriptstring, true);
        }
    }

Please see the screenshot.

Thanks,
Shinu.
