To Select Multiple Value in ListBox Control using following code.

for each(Listitem i in Listbox1.items)

{

if(i.selected)

{

TextBox1.Text+=i.value;
}
}

Explanation:

To Create object for list box control and using one for loop to travel up to all elements of corresponding listbox control and upend all value to one textbox.

Demonstrates how to use custom validation on a form by checking to see if a string in a TextBox is not the same with a string from an array (or database), case in which it displays ‘Name Already Exists’.

Start a new ASP .NET Web Application project named customValidation and drag a TextBox, a Button and a CustomValidator to WebForm1.aspx.

Now set the ErrorMessage property of CustomValidator1 to “This name is already taken”. Also set the ControlToValidate property to TextBox1.

Write following C# code in your Code behind file

string[] emp_names = { “Mahesh”, “jerson”, “Narayanan” };

public void validateName(object sender, ServerValidateEventArgs e)
{
foreach (string name in emp_names)
{

if (e.Value == name)
{

e.IsValid = false;

}

}

}

At this time we only need to set the ServerValidate event to validateName. We’ll do this using the Properties window of Visual Studio .NET:

If we have 4 or more check boxes . then it is little difficult to maintain different names for checkboxes.

the best way is to use array as name of checkbox.  (in_array function)
Example :
<input name=”n1[]” value=”Art” type=”checkbox” <? if (in_array(”Art”,$_POST[n1])) echo “checked”; ?>> Art<br>
<input name=”n1[]” value=”Fashion” type=”checkbox” <? if (in_array(”Fashion”,$_POST[n1])) echo “checked”; ?>> Fashion<br>
<input name=”n1[]” value=”Film” type=”checkbox” <? if (in_array(”Film”,$_POST[n1])) echo “checked”; ?>> Film<br>
<input name=”n1[]” value=”Music” type=”checkbox” <? if (in_array(”Music”,$_POST[n1])) echo “checked”; ?>> Music<br>

so when you post now the checks will be retained.

here is the function:

function CropSentence ($strText, $intLength, $strTrail)
{
$wsCount = 0;
$intTempSize = 0;
$intTotalLen = 0;
$intLength = $intLength - strlen($strTrail);
$strTemp = “”;
if (strlen($strText) > $intLength) {
$arrTemp = explode(” “, $strText);
foreach ($arrTemp as $x) {
if (strlen($strTemp) <= $intLength) $strTemp .= ” ” . $x;
}
$CropSentence = $strTemp . $strTrail;
} else {
$CropSentence = $strText;
}
return $CropSentence;
}

to call the function

$strTemp = CropSentence($r[”event_description”], 150, “…”);

to call the function

$img_prop=try_img_scale(”admin/uploads/1.jpg”,200,200);

function defenition

function try_img_scale($img_path, $width, $height)
{
$img_prop=getimagesize($img_path);
$img_width=$img_prop[0];
$img_height=$img_prop[1];
if($img_width>$width || $img_height>$height)
{
$scale_width=($width/$img_width)*100;
$scale_height=($height/$img_height)*100;
if($scale_width <= $scale_height)
$scale_val=$scale_width;
else
$scale_val=$scale_height;

//$scale_val=$scale_width < $scale_height?$scale_width:$scale_height;
$img_prop[0]=($scale_val/100)*$img_width;
$img_prop[1]=($scale_val/100)*$img_height;
}
return $img_prop;
}
