Re: Calendar Control in ASP.Net using Ajax Toolkit

22-Dec-14 4:42

I used a Calendar control in my ASP.Net code. I have three text boxes with three different calendar controls. But when I click on one calendar, other two calendars are also opening up. Also required field validators error messages are also showing beside the textboxes control.
Here is my code

XML

<td width="34%"><asp:TextBox ID="txtClaimDate" runat="server" Width="100%" ></asp:TextBox>
                <asp:ImageButton runat="Server" ID="img3" ImageUrl="~/Images/Calendar_scheduleHS.png"
                         AlternateText="Click to show calendar" /><br />
                     <cc1:CalendarExtender ID="CalClaimDate" runat="server" TargetControlID="txtClaimDate"
                         Format="yyyy-MM-dd" PopupButtonID="Image1">
                     </cc1:CalendarExtender>
               </td>

XML

<td width="16.5%">
                       <asp:TextBox ID="txtInDate" runat="server" Width="100%" />
                       <asp:ImageButton runat="Server" ID="Image1" ImageUrl="~/Images/Calendar_scheduleHS.png"
                           AlternateText="Click to show calendar" /><br />
                       <cc1:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txtInDate"
                           Format="yyyy-MM-dd" PopupButtonID="Image1">
                       </cc1:CalendarExtender>
                   </td>

XML

<td width="16.5%">
                       <asp:TextBox ID="txtPuDate" runat="server" Width="100%" />
                       <asp:ImageButton runat="Server" ID="ImageButton1" ImageUrl="~/Images/Calendar_scheduleHS.png"
                           AlternateText="Click to show calendar" /><br />
                       <cc1:CalendarExtender ID="CalendarExtender2" runat="server" TargetControlID="txtPuDate"
                           Format="yyyy-MM-dd" PopupButtonID="Image1">
                       </cc1:CalendarExtender>
                   </td>

Now when I click on second calendar "txtIndate/CalendarExtender1" the other two calendar "txtClaimDate and txtPuDate" are opening up.
Please tell me how Can I stop this.

Your help is much appreciated.
Thanks
Happy Coding!

Issue in opening zip file created by Ionic.zip

22-Dec-14 4:51

I solved this upto one extend. I mean PopupbuttonId is same. It should be the image ID of their respective button. But now when I click on any calendar, It shows "*" for the fields. This means Requiredfieldsvalidator's error messages are "*" so it shows all the fields with "*". Please help in solving that.

Your help is much appreciated.

Hi

I have a textbox which should take phone numbers. ASP.NEt code is as below

XML

<asp:TextBox ID="txtPhone" runat="server" Width="100%"></asp:TextBox>

                    <cc1:MaskedEditExtender runat="server"  ID="mee" Mask="(999) 999-9999"
        TargetControlID="txtPhone"></cc1:MaskedEditExtender>

When I enter 10 digit phone it shows exactly what I want it to do. But if I enter wrong phone number and want to clear using backspace. It is not doing anything.
Ex: my input: (123) 122-1233
But I want to enter (123) 123-1234
It is not letting me to backspace and enter. I have to refresh the whole page again to give correct data.

Your help is much appreciated.
Thanks

ASP:Literals

sudevsu17-Dec-14 9:51

17-Dec-14 9:51

When you have ASP:Textbox, ASp:Dropdownlist etc, why do people use ASP:Literals? Is there anything special about it. Which one is old control ASP:Textbox or ASP:Literal?

Your help is much appreciated.
Thanks

In HTML you can put text anywhere without any specific tag around it, however how you do it from aspx form when that text should be dynamic? You use asp:Literal...You can see that there is no room to compare Literal to Textbox...One is for text display, where the other is for text input...
And there is no such thing between Literal and Textbox as old or new - both part of the same control package of ASP.NET...

Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

sudevsu18-Dec-14 2:48

18-Dec-14 2:48

Oh so you mean say ASP:Literals are not something Old. I was in a misperception thinking that "developing a website with just only Literals is old fashion". Is that not true?

Your help is much appreciated.

ONLY literals is not an old way - it's a stupid way (excuse me to be harsh a bit). Every element has it's rightful place on your palette of controls. Use them wisely...

asp:Literal is my favourite as it gives me complete control over the rendered html.

You can render anything like, but not limited to, scripts, conditional text, your custom tag, ordered or unordered lists, or a bunch of data from database or rss feed with much ease.

Life is a computer program and everyone is the programmer of his own life.

But is not true that ASP:Literals doesn't take CSS Styles ? Correct me if am Wrong

Hello Experts,

You will need to rebuild it in VS2010.

Well, I am afraid that really tells us nothing. We cannot see your screen or read your mind. You need to do some proper analysis of your problem and present a detailed explanation if you want some assistance.

Is there any way I can send you screen shots so that you can have better idea. I really appreciate your patience in answering but I really don't know anything in Dot.net. I am learning now. I am going to blogs, videos, tutorials and more. Please do tell any way that I can make you aware of the error in clear.

Your help is much appreciated.

Sorry, you have to provide the information here. And if you don't know anything about it, then the error could be something as basic as a spelling error, which tends to throw everything out of line. By the way, you have posted this in the ASP.NET forum, and tagged it Visual Studio; so what exactly is the code you are trying to create?
