I am using Visual Studio 2008. I have created a login screen and when user enters invalid userid or password, I am displaying error message in label by checking the database.
I am clearing the label, txtUserName and Password on click of Refresh button. But still the label message is appearing because UserName and Password controls are not clearing
I have set enableViewState to false, why my textbox still remain my last value after i hit the postback button?

I am trying to avoid enabling EnableViewState..Sample code as you can see has 1 repeater and 2 textboxes inside. I bind the textboxes at page init. After a postback I want to get the updated data from the client & save in a db. The Request.Form contains the data keyed with autogenerated client ids but the repeater has 0 items after the postback. So my options seem limited to.a. Enable viewstate so I can pull the data from the repeater using Control.Find(...)b. iterate through Request.Form and find my textbox values...ultimatly the goal is to to render data from a datatable to some textboxes, allow the user to make changes then save these changes. I'd like to avoid viewstate if there is a clean alternative..ASPX:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Foo.aspx.cs" Inherits="Ads_Foo" EnableViewState="false"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-

If we set enable view state = false of a page then can we maintain the view state of that page ?
View 1 RepliesI have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
I have made EnableViewState="False" in @page directive. But still all all controls in page maintaing values even after submit.
View 2 RepliesI have developed a web application in Asp.net with C#. My requirement is to add an extra property to textboxes in all forms. The property should be "SID". I don't want add an exterban control i want to add extra property with the available textbox.
View 1 RepliesI have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).

Is this possible without setting 'ValidateRequest' to false?
In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?
I have a panel that contains several controls.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
I've GridView with Template field as
<asp:TemplateField HeaderText="Review">
<ItemTemplate>
<asp:ImageButton ID="imgBtnReview" ImageUrl="~/images/agt_reload.png" runat="server" Visible="false" CommandName="Review" CommandArgument='<%#Eval("id")%>' />
</ItemTemplate>
</asp:TemplateField>
Gridview is bound to a table. If a row in table has price greater than zero then the above mentioned Imagebutton should br visible in that row only.
Is it possible to do so.
I have a validator that check an input.
i what that the validator displayed "valid" if the value is valid, and "invalid" if the value is hasnt passed the validation.
can manage without adding an additional label for the valid state(by setting the visibility: true/false)?
does the validator control has am alternative value, or i have to override it?
Is there a way to disable request validation for just certain textboxes instead of the whole page? I'm using Server.HtmlEncode/Decode because users are legitimately using < and > characters but I don't want to use ValidateRequest="false" on the whole page because someone could add a textbox later and forget to escape the input in which case I would want validation to occur so the error would be discovered rather than be vulnerable to html injection. It seems like there has to be a simple solution but I'm not having any luck finding it.
View 1 RepliesIs it possible to send a html text entered in asp.net text box without making validaterequest to false.
View 1 RepliesI have a textbox with a regex validator attached to it and some stuff in the ontextchanged code behind. This all works fine unless I start the textbox out with Visible=false. Obviously, I'm setting the textbox.Visible to true later on in the codebehind, but when I do this, no postback occurs when the text changes. I'm pretty sure I have isolated the cause to when I change the visible property, but has anyone seen anything like this or know some sort of work around?
View 1 RepliesI have a textbox which can be left blank or contain a date. If the textbox has a date I want the 2nd textbox's value to be set to the value of a session variable. I need this to happen before the update sql is performed on postback.
This is the code I have. But the textbox is coming back as nothing. Whether it has a value in it or not.

What does EnableViewState on a HyperLink do or mean?
<asp:HyperLink ID="RegisterHyperLink" runat="server" EnableViewState="false">Register</asp:HyperLink>
What does it mean? and what will it do if I set it to true.
This problem is stopping me from winding up my project. I have a webform where there is a pop-up page that populates one text box and 2 dropdowns. And I also have a checkbox list that does a postback. Whenever the checkboxlist does a postback, one of the dropdownlist's value is reset. It happens with only one dropdown list. The text box and the other dropdownlist retain their value. I have put enableviewstate = true at both the page level and control level.
View 6 RepliesI have a 32 bit number in my DB/ DAL layer that is used to represent some yes/no facilities about hotels. so I for example bit might mean "has swimming pool", bit 2 might mean "reception desk" etc etc.Currently I have some code in the BLL that says if (number and 2) = 2 then .ispool = true - this is repeated for any many boolean hotel referances I have.What happens then is in the UI have then say something like if .ispool = true then display swimming pool icon.
Then it occurs to me that I am testing the value twice
1) To test the bin to bool in the BLL and create the structure
2) to test the structure to dislay the icon.
If I move the if (number and 2) = 2 to the UI I get the same result with one less if.Is there some better way or code do deal with this, maybe loop through the structure or something like that or an asp way that is more suitable to deal with binary representation of boolean's.
