Good effort, my 5

Solution 2

They are both controls, so you could just do a TextBox.Text == Label.Text in your code-behind after adding the id and runat="server" attributes to the label control in your markup.

Right, my 5

Solution 3

You can try as below.

For Case Insensitive Compare

C#

//Case Insensitive Compare
if (string.Compare(TextBox1.Text, Label1.Text, true) == 0)
{
  //Matching
}
else
{
 //Not Matching
}

For Case Sensitive Compare

C#

//Case Sensitive Compare
if (string.Compare(TextBox1.Text, Label1.Text, false) == 0)
{
  //Matching
}
else
{
  //Not Matching
}

This is not a best practice. Compare should only be use for sorting.
You should use Equals instead and specify the StringComparisonOptions.

prdpvts - Please do not provide personal email in forum website, which may cause spams. CodeProject does sends auto emails for every comment/answer.

RaisKazi 5-Aug-11 9:58am

what not making possible to you? You just have to copy above code and replace "TextBox1" and "Label1" by your control names. I assume you are using Asp.Net Server controls.

prdpvts 8-Aug-11 3:37am

yes...i m using asp .net ...in that it give only one color ..only the color of "no"...it doesn't show the color of "yes"...

Solution 5

if(textbox1.text== label1.text)
{

statements;
}
else

{
statements;
}

What the hell is the point in posting the same answer other people posted two days ago, esp for a user who is obviously too stupid to follow directions ?

Same reason as the above two members. I would suggest that you begin to take the advice of the more senior members. They are trying to help you and you seem to be ignoring their suggestions.

Solution 4

You should use Equals to compare both Strings, and it's also a good practice to specify the StringComparison options.

Read this for more info:
Best Practices for Using Strings in the .NET Framework[^]

C#

if(TextBox.Text.Equals(Label.Text, StringComparison.Ordinal))
{
  //Values are equal
}
else
{
  //Values are not equal
}

Hope it helps
