You cannot store an integer value with a leading zero...Actually why do you want to do that?

Actually my string will be like this...

Mainstring = "009816-9234";

I am splitting this and taking part in to integer and add one value to it and then send as parameter to a query to check this in database.

i.e string str = "009816";
_zip = Convert.ToInt32(str);
_zip = _zip + 1;

ProcessthisinQuery(_Zip)
{
}

so how come it makes a difference ... i mean _zip now contains 9817. Whether 0009817 or 9817 both refer to a same value...

No, both are not same....
When i query like this...
Select * from Table Where Zip = '009817' Which gives results

But when i use the same query with zip = '9817'

Select * from Table Where Zip = '9817' Which doen't gives any results

The Data in the column contains with zip as 009817. So second query doen;t match

Re: Zero's were getting trimmed when string convert to integer.

Ok got it...the zip column in your table is a non integer column like varchar or nchar etc. So when you pass '9817' its recognized as 9817 text not as 009817 and hence you are not getting the desired result.

For your problem after

_zip = _zip + 1;

Convert the _zip back to a string and pass it to the query... i mean

use the following...

-zip.ToString("000000") gives the value 009817. Now pass this value to your ProcessQuery(string zip) method as a string value.

Thank you for your answer, and have another doubt that the value is dynamic, i dont know, how many zeros will be in starting of the string..
Whether it will be '09817', '009817', '000817', '00081'

Re: Zero's were getting trimmed when string convert to integer.

For that instead of using ToString("000000") use -zip.ToString().PadLeft(length,'0')...where length can be the required number of digits...

Hi,
Assume ID for your datalist control is dlist.
Then

string szChandu = (dlist.Items[i].FindControl("Label1") as Label).Text;

should work.
Please note i in the above code is the ith row of the datalist.

ASP.Net Multiline Text Box

Hello,

I am trying to use a multiline textbox in asp.net that will automatically move with the browser as it is resized both horizontally and vertically. I have tried using CSS and percent See Example Below:

***************************************************************************************

<asp:textbox id="txtInfo" runat="server" height="20%" textmode="MultiLine" xmlns:asp="#unknown">
Width="99%" Wrap="False" Font-Bold="False" Font-Names="Courier New"
Font-Size="Medium">

***************************************************************************************

I have also tried using java script

***************************************************************************************

// Subscribe to the onresize window event

window.onresize = Resize;

// Resize the textbox
Resize('txtInfo');

// Resizes the supplied textbox name
function Resize(textBox) {

// Get height - take margins into consideration
var height = parseInt(document.body.clientHeight) - (parseInt(document.body.currentStyle.marginTop) + parseInt(document.body.currentStyle.marginBottom));

// Get width - take margins into consideration
var width = parseInt(document.body.clientWidth) - (parseInt(document.body.currentStyle.marginLeft) + parseInt(document.body.currentStyle.marginRight));

// Set the textbox height and width

if (textBox != null) {
document.getElementById(textBox).height = height;
document.getElementById(textBox).width = width;
}
}

***************************************************************************************

Anyone who can provide me with a little direction would be greatly appreciated!!!

Thanks

Ryan

Just set

Width = 100%

and

Height = 100%

of a textbox. and its done. dont forget to put the text box inside the < div > or < table > tag which also has width = 100%.

So I think your code is ok, no need to use java script just make sure that all the containers of that text box are set to 100% width.

Okay, I tried this (I included the whole page as it is not too much) This code is auto generated by Visual Studio 2008.... The text box resizes by width, but not by height. (I had to remove all greater than and less than's so it would display in the post correctly)

Thanks for your Time

OK. This is odd problem because of soo many browsers we have. every browser render the page differently, so its very difficult to make height 100% in all the browser.

You need to set margin and padding to 0 to avoid scroll bars, if scroll bars are visible, you will not able to get 100% height. also in IE you can use min-height : 100%;.

try this in < style > tag

*
    {
        margin: 0;
        padding: 0;
    }
    
html
    {
        height: 100%;
    }
    
body
    {
        height: 100%; 
    }

or you can just set the Rows of multi line text-box to like 150 or something, or you can modify your java script to change the Rows based on Page height.

I am not sure if this will work in all the browsers.

I am still having no luck. I have set an HTML style overflow: hidden; clip: rect(0px, 0px, auto, auto); margin: 0px; padding: 0px; width: 100%; height: 100%; min-height: 100%;

The Form has a style:
style="margin: 0px; padding: 0px; width: 100%; height: 100%; overflow: hidden; position: relative; top: 0px; left: 0px;">

The Div that contains the textbox has a style

style="margin: 0px; padding: 0px; height: 100%; width: 100%; position: relative; overflow: hidden;">

The text box is set up:

<asp:textbox id="txtRiderInfo" runat="server" height="100%" textmode="MultiLine" xmlns:asp="#unknown">
Width="99%" Wrap="False" Font-Bold="False" Font-Names="Courier New"
Font-Size="Medium" ReadOnly="True" Rows="100">

Unless I set the rows to a large number, the textbox stays small.

With all the years the web has been around, why are the amount of controls and the abilty to make them behave so difficult??

This is a 10 second problem to fix in Java apps, VB6, VB.net, C#......

I do appreciate your help, just can't believe the solution is so complicated.......
