The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."Solved"

Hi,

From last day this error is fucking my happiness.I search @ all forms 'n Blah Blah Blah i didn't get what i need.last i Solved it myself.

In my early post i'm tell how to copy text from one text-box to another.it's done by one java-script.

when i put ajax over my pages this showing me this error

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)

when i eliminate ajax it's working fine.but that's not a solution.On my search one told me that replace = with # i done it but i got another error on java-script.

so i change the way i'm getting the value on the text-box 'n i done it

Previously it is in this way

var paramVal1 = document.getElementById('<%=txtcheckin.ClientID%>').value;

Later i change to this

var paramVal1 = document.getElementById('txtcheckin').value;

Have a nice day... 'N happy Coding :)

solve width problem in ASP.Net Password control

I came across a strange issue with Password input and IE browser. I have set the width property as same as that of the other controls. But while rendering it in IE, the width of Password field was coming as around 10 pixel less than the other control. The best way to get rid of this issue was using CSS.

Before

After

add these changes in ur css
===========================================================

<style type="text/css" >
       .TextBox
       {
           font-family: Arial, Tahoma, Verdana, Calibri;
           font-size: 12px;
           color: Black;
           height: auto;
           width: auto;
       }
   </style>

=========================================================

<html xmlns="http://www.w3.org/1999/xhtml" >
<body>
<form id="form1" runat="server">
<table width="25%">
<tr>
<td style="width:100%; text-align:left">UserName: </td>                  
<td style="width:100%; text-align:left">

Check RadioButton/CheckBox Depending Upon Data in DataBase

hi eveybody,

Saving checked items in RadioButton/CheckBox to database and showing that back like edit command.

For that i first saved that checked item in checkbox list to database by comma separated form like (TV,Fridge)

Storing data to database Which where items are checked

Code

            foreach (ListItem li in Chk_ItemList.Items)// here u will get all the item in the CheckBoxList
            {
                if (li.Selected == true)// here i filter the selected from the list
                {
                    _itemlist = _itemlist += li.Text + ","; //here i add the selected item one by one separated by comma ex:tv,coller
                }
            }

here

Chk_ItemList is my Checkboxlist id

_itemlist is a string where i storing my checked item

and normally storing to database :) .and show the content in a grid i chosen here a datagrid.

On displaying back Which where items are checked

i taken the SelectedIndexChanged event of grid and

        string _Item = grd.SelectedItem.Cells[1].Text.ToString(); // here i'm getting the string TV,Fridge
        string[] Seperator = new string[] { "," }; //i define here which one is ti be eliminated from that string and i'm calling the split function
        string[] strsplitarr = _Item.Split(Seperator, StringSplitOptions.RemoveEmptyEntries);//RemoveEmptyEntries is for remove blankspace from the string and storing that string in an array
        foreach (string _chkitem in strsplitarr)
        {
            Chk_ItemList.Items.FindByText(_chkitem).Selected = true;// by the help of foreach i'm taking all the entry of an array and finding the text in checkboxlist if i find i mark it as selected :)
        }

'n i created a demo of it u can download that from here

To check given String is Url or not using Regular Expression

Hi everyboday,
Few days back my friend ask me abt validating a string that it contain a url or not.
Visual stdio is giving us a in-build option to check this so what v need is to cal this control on server side and validate it Simple :)

To call Regular Expression on server side v need to add a name space
using System.Text.RegularExpressions;

validate URL's without http

Private bool ValidateUrl(string url)

{

// regex pattern for url validation string

Regex RgxUrl = new Regex("(([a-zA-Z][0-9a-zA-Z+\\-\\.]*:)?/{0,2}[0-9a-zA-Z;/?:@&=+$\\.\\-_!~*'()%]+)?(#[0-9a-zA-Z;/?:@&=+$\\.\\-_!~*'()%]+)?");
if (RgxUrl.IsMatch(url))
{
return true;// string url contain valid url
}
else
{
return false;// string url contain invalid url
}

}

validate URL's with http

Private bool ValidateUrl(string url)

{
System.Globalization.CompareInfo cmpUrl = System.Globalization.CultureInfo.InvariantCulture.CompareInfo;
if(cmpUrl.IsPrefix(txtUrl.Text, "http://") == false)
{
txtUrl.Text = "http://" + txtUrl.Text;
}
Regex RgxUrl = new Regex("(([a-zA-Z][0-9a-zA-Z+\\-\\.]*:)?/{0,2}[0-9a-zA-Z;/?:@&=+$\\.\\-_!~*'()%]+)?(#[0-9a-zA-Z;/?:@&=+$\\.\\-_!~*'()%]+)?");
if (RgxUrl.IsMatch(url))
{
return true;
}
else
{
return false;

}
