Hi,
In my project I have 3 forms. Home.aspx, CreateInfo.aspx and CreateInfoNext.aspx. CreateInfo and CreateInfoNext I have defined Back link button. when click on back link button it display previous page.
this working fine. but my problem is I have some validators in each page.
am validating on server side and displaying it under ValidationSummery field validator. If I gave some thing wrong in one field and click on Next button, it is validating and showing error and it is not forwarding to other page.Its OK. Now I entered right text and click on next button it is validating and going to other page. This is ok. the real problem is when I click back button it should go to previous page.it is going but showing error messages under ValidationSummery field validator.

pls see the follwing code:

<asp:LinkButton CausesValidation="false" ID="linkButtonBack" CssClass="linkbold" PostBackUrl="javascript:history.back();" runat="server">< <%=resourceManager.GetString("CMN_TOP_BACK")%></asp:LinkButton>

pls help me in this.

Thanks

Heh... I had the same problem...

I changed all my RequiredField validators to Red Label's, and manually checked them...

RangeValidators were more... Interesting...

if the RangeValidator is checking textBox1 for a value, just go:

textBox1.Text = "";<br />
Response.Redirect("www.google.co.za"); // Replacing with whatever

Since the textBox is empty, the RangeValidator is ignored...

Although, if you find some OTHER way to do this (Possibly keeping the RequiredField Validators), please give me a yell Sigh | :sigh:

Hi Everyone,
In my application i am using Label and DropdropList, on the selection of Dropdownlist,the label is disappear from the Form.

i am using like this

<div>
<asp:label id="L_Country" runat="server" />
</div>

<div>
<asp:ropDownList ID="DDL_LCD_Country" runat="server" OnSelectedIndexChanged="DDL_LCD_Country_SelectedIndexChanged"
AutoPostBack="true" >
<asp:ListItem Text="Select Country"></asp:ListItem>

</asp:DropDownList>
</div>

Please help me, where i am making mistake.

Well, first you've not shown any code that will hide the label. Second, do you NEED to do an autopostback, or is that only to hide the label ? If you need to postback anyhow, then in DDL_LCD_Country_SelectedIndexChanged, set L_Country.Visible = false. BTW, your naming standard is really nasty, does a company enforce that ?

If you don't need the postback, do it in javascript.

well, you've found out for yourself just how nasty code can get when you use goto.

1 - you don't have a label called label1 in this code
2 - I see no reason for you to use a goto here, in any case.

I have never used goto in code, not once. I have also never written code to avoid goto. I have instead avoided some nasty constructs.

goto is unstructured programming. You may need to consider revising your design for better programming constructs instead.

Do you know how I can link scrollbars of two textboxes. What I need to do, is to move the scrollbar of textbox1 when the scrollbar of textbox2 is moved and visa vesa.

You'd need to check if you can catch a scroll event on a textbox in javascript, then when one scrolls, scroll the other one if it's not at the same scroll pos. You need to check first tho, or you risk creating an endless loop

Modal Popup Window Problem.

SekharOne17-Apr-08 19:49

SekharOne

17-Apr-08 19:49

How can I display a Modal Popup window in ASP.Net using vb.net 2005. I had used the code bellow to show a popup window.

ClientScript.RegisterStartupScript(Me.GetType, "popup", "window.showModalDialog('abc.aspx','_blank','height=450px,width=625px,menubar=no');", True)

But this code creates a problem i.e., when i click on a button on the popup window it again displays the same form in another window non modally. And if i open the window non modally i.e., using the code bellow i dont get any errors.

ClientScript.RegisterStartupScript(Me.GetType, "popup", "window.open('abc.aspx','_blank','height=450px,width=625px,menubar=no');", True)

Please Help how to prevent this.

Thanks in advance.
