Why don't you trap for that. if your table field does not allow nulls then you cant insert a null.what you can do is to trap for that and have the reserved word that you will use if the textbox is empty.

You should set a default value of 0 (zero) for the monitors, scanners and printers fields such that when you go to pass the data to the database all of the items have a valid value (zero should be a valid count for items denoting that whilst they may have 1 scanner, they have no printers or monitors).

printer.computer,scanner lines are giving error

try this
in your table set default value of printer, scanner.. parameter is 0
or use in code
if(txt_printer=="")
{
printer =0;
}
else
{
printer =txt_printer.Text;
}
same for scanner . & .........

If you are going to do it like that, do it this way:
int printer = (string.IsNullOrEmpty(txtPrinter.Text) ? 0 : Convert.ToInt32(txtPrinter.Text);
Apply the appropriate conversion to txtPrinter.Text.

Dear All,
i have following code
function displayControlName(src,pText)
{
var msg2Display = document.getElementById('spMsg');
msg2Display.innerHTML += '<input type = "button" value="'+src+'" onclick="return displayMsg(src,pText)"/><br>';
return false;
}
function displayMsg(src,pText)
{
alert(src + ' you are here');
return false;
}
I am looking to pass "src" and "pText" javascript variable to a function called "displayMsg", but I have tried different ways to pass the variables from first method "displayControlName" as i have tried
displayMsg(src,pText), displayMsg('+src+','+pText+') and a little more but none worked for me.
any ideas how to pass the variable name src and pText to the javascript function displayMsg from method displayControlName and I am trying to pass it in this statement onclick = "return displayMsg(src,pText)"?

this will be the correct way
displayMsg(src,pText);
and i see you have done it but the question is that these parameters have you declared them anywhere ? show u the part you tried to execute and show us where you declare the parameters to pass to the function.

those variables are as the function args and I am sending only text value to these args
as you see
the function requires two args
function displayControlName(src,pText) and I am only printing that two variables passed to function.
here I am passing var to that function
menuLink.Attributes["onclick"] = "return displayControlName('" + item.Text + "','" + item.Parent.Text + "');";
both item.Text and item.Parent.Text are there but the
onclick="return displayMsg(src,pText);" doesent work.

Look at Prakash , that is exactly what you need to do. your variables are not recognized, they are treated as string.

You are adding the input control in the spMsg control like following
msg2Display.innerHTML += '<input type = "button" value="'+src+'" onclick="return displayMsg(src,pText)"/><br>';
When the onclick event will be attached on the input button the “scr” will be unknown.
try this
function displayControlName(src, pText) {
var msg2Display = document.getElementById('spMsg');
msg2Display.innerHTML += '<input type = "button" value="'
+ src + '" onclick="'
+ "return displayMsg('"
+ src + "','"
+ pText + "')"
+ '"/><br>';
return false;
}

thanks, your print the following but no event is attached with the button
ButtonpTextValue')"/>
Button mean the HTML control button and pTextValue mean the value which is in the pText Variable
it means it prints one button control with other text in the screen while no event is attached with the button control.

Should we declare any directive or name space to use AD rotator control?
|
|
|
|
|
AdRotator class is present in System.Web.UI.WebControls namespace, by default you get this in you toolbar. To use this you don’t need to declare any directive.
You can find many online examples of AdRotator implementation in Google.
WWW, WCF, WWF, WPF, WFC .... WTF
|
|
|
|
|
you just simply drag n drop ad rotator control from toolbar and use it in source file no need to declare any directive
|
|
|
|
|
can we use form view control to display a image? for me neither image or AD rotator control is working
|
|
|
|
|
Form view control is basically used for defining templates for insert/edit/display of database fields, It can’t be used to display image.

sorry if this is the wrong forum to post this in...please direct me to the correct one if I'm in error
fairly new to c# asp.net web development...want to know if anyone has a couple of url links that i can go to, to download some free web site templates for c#...i don't really have a css design eye...if they are also seo friendly, that's a bonus too.
thanks

You are not really looking for a template, which would give you a set of predefined pages, operations and structure. Themes or skins are what can be used to give a look and feel to a site, usually though use of CSS.
