Hi I developed a web application using 1280x1024 resolution. But the end user uses a different resolution which makes the page go into horizontal and vertical scrolls. Is there anyway I can make my webapp to resize based on user screen resolution?

textbox validation please help

HI,
I have some text in a textbox that is reading directly from a database. My application is supposed to allow user to update this text, so it directly affects in the database content.

Now in my text there are some special characters like : , ' href < >. The code works fine as long as the text data in the text box does not contain these characters. As soon as it encounters data with these characters it does not update the database, any suggestions to tackle this. I already tried, <pages validaterequest="false"> in web.config with no success

It would be helpful if you described exactly what is happening, not just what is not happening.

Thanks for the response

I have text box reading text content from database. When I change the text in the textbox and do update, it does not update in the database. I traced the problem to special characters like : and ' in the text field. When the text in the text field does not contain these special characters, it works fine. How to get around these special characters?

You don't have to get around any characters, you just have to treat them properly.

What do you do to update the database? What method are you using? Do you create an SQL query yourself? Do you use a parameterised query or do you concatenate the values into the query?

I see no reason why a colon would be any problematic, but an apostrophe is a common problem if you concatenate strings into the query and don't encode the data properly first.

Problem in Nested GridView While setting Pagesize

Anupriya.G17-Mar-07 9:53

17-Mar-07 9:53

I have implemented nested gridviews with custom paging using Objectdatasource.

I want to allow the user to change the pagesize after initial display.

For that I have a text box to collect the "Records Per Page" and a Button called "Change" below the parent gridview.

If I give value in the "Records Per Page" textbox and and click on "Change" button, the same pagesize should be set for parent gridview and also for all the inner gridviews.

I have implemented the same in my code. But only the parent gridview's pagesize is changing.Though I am setting the modified pagesize for child gridview , it is not reflecting in my output. Always it displays records according to the initial pagesize I have set in the html part. Can Anybody come across this issue?

Can Anybody tell me how to proceed on this?

hi!
After entering username and password if user will directly prss Enter key without pressing tab or instead of clcking on "LogIn button"
further processing should start.
This is working fine in Internet Explorer but not in Mozilla Firefox.
Please suggest some solution.

Code snippet is as follows:
In Aspx.cs =>
txtPassword.Attributes.Add("onkeypress", "return clickButton(event,'" + btnLogin.ClientID + "')");

In Aspx

function clickButton(e, buttonid)
{
var bt = document.getElementById(buttonid);
if (typeof bt == 'object')
{
if(navigator.appName.indexOf("Netscape")>(-1))
{
if (e.keyCode ==13)
{
bt.click();
return false;
}
}
if(navigator.appName.indexOf("Microsoft Internet Explorer")>(-1))
{
if(event.keyCode == 13)
{
bt.click();
return false;
}
}
}
}

I just recently wrote and article on this:
http://www.codeproject.com/useritems/EnterKeyToButtonClick.asp[^]

The javascript code in this article works for both IE and firefox.

NOTE if you are using a .net 2.0 login control there is a different way of doing it.

Hope that helps.

Hello friends..i am using a repeater inside datalist. This is classifieds page displaying different categories like jobs, filmmakers, housing, etc ..Each of these categories have 1 or more subcategories..
I use repeater inside datalist. Each datalist is filled by category name and based on that repeater is filled.
the funcionality is working but the design is disturbed. Repeater may contain more or less items. if repeater contains less items than the neighbor then that much blank space is displayed.in Internet explorer.
In IE, it browser places each main item in a row.
In Firefox the design is disturbed totally.
how to remove this blnk space..
Please tell me..if u have suggestions...waiting

Jith-

Calling a page via menu will always load the page, even if it is the same.
The best way you can do is use AJAX with webusercontrol.

Dear gauthee,
If you can create a base page that also serves the same purpose.

But there is a way out using Javascript to disable all the controls ....
use "getElementsByTagName()" DOM function.

How to do it:
===========================================================
When all the control is rendered it generates HTML control in browser.

So in your rendered page you get

<input type="textbox" ....>
<input type="chekbox" ....>
<input type="button" ....>

instead of

<asp:textbox...> or <asp:checkbox...>

So you can write a javascript function that will
1. First collect all the IDs of controls having tag name as
2. Iterate through the array of IDs and set the 'disabled' property of all the control.

The javacript function may look like this one.

function DisableAllControls()
{
    var arrControls = document.getElementByTagName('input') 
    // since we are trying to gather all controls having <input> tag 
    // returns an array of control's ID ..so each array
    // element is a control of your page.
        
    for(int i=0;iterate upto arrControls.length)
    {
        arrControls[i].disabled = true;
    }
    // setting each control's 'disabled' property to true
    // to disable all the control.
}

When to call this javascript method:
===========================================================
When page has completed rendering process then this method must be called.

So at the end of your aspx page call this function to disable all controls.

Reusability:
===========================================================
The very same function you can use to enable all the control if you pass some true or false as a parameter to the function so that the sae function can be used for enabling or disabling.

Hope this helps ... Big Grin | :-D

Thanks,
Arindam D Tewary
