All server controls have properties. You access a property's value using the syntax:
ServerControl.Property

The TextBox control has a Text property for retrieving or setting the text in the box. If your TextBox is named "MyTextBox", you would retrieve its value in C# this way:

string myText = MyTextBox.Text;

You might benifit from a look at the QuickStart tutorials on http://www.asp.net[^].

To get the value of a HtmlTextBox control from C# code behind, you have to convert the Control to a server control, not a web server control. just click on the control and select "Run as server control". set the ID propety in the preorties window.

or you can add 'id="UName" runat="server"' this snippet in the textbox tag in the HTML view.
example

initially your control looks like the below,
<input type="TextBox">
alter it to

<input type="TextBox" id="UName" runat="server">

know at the code behinde

you can use the below code to get the value

System.Web.UI.HtmlInputText txtName = new System.Web.UI.HtmlInputText();<br />
txtName = (System.Web.UI.HtmlInputText)this.FindConrol("UName");//Provide the ID you have given to the cotrol<br />

now txtName.Value will give you the textbox value

hope this helps you

Cheer.

I have a windows app project that I need to create an installer for distribution. How do I do that? Do I need a third party software?

Your question doesn't seem to refer to ASP.NET. You may want to post questions like these instead to a language-specific board in the future.

That being said, you could use the VS.NET's Setup project type to create a windows installation application.

Hi,
On click of the button call a javascript method in code behind,

Below is .aspx.cs page code:

For eg : Let server control button id be 'btnSave'

btnSave.Attributes.Add("OnClick","javascript:return ValidateTextBox();");

.aspx page code :

<script language="javascript">

  function ValidateTextBox()
  {
     //for eg:let the textbox id be 'txtName'

     //First check whether the textbox exists 
     if(document.getElementById("txtName")!=null)
      {
        if(isEmptyCheck("txtName")==true)
	{
		alert("Text box value is empty,please enter value");
		return false;
	}
      }
  }

  //function to check whether text box value is empty or not

  function isEmptyCheck(X)
{
if((document.forms[0].elements[X].value=="") || (document.forms[0].elements[X].value.substring(0,1) == ' '))
	{
		return true;
	}
	return false;
}//end of function
  

 </script>

Hope this helps you... Smile | :)

set to properties for the HTML table. set ID and runat="server". or if you are adding the the table at design time, just right click on the table and select "Run as server control" and set ID property in the properties window. or go to HTML view and add the following line to the HTML table tag.
id="GiveSomeidhere" runat="server".

let us say id="TableID" runat="server"

now

HtmlTable htmlTable = new HtmlTable();
htmlTable = this.FindControl("TableID");

now you can do your codin using this htmlTable variable.

hope this will help you.

Hi,
I was wondering if I can filter the FileField control (used to upload files) to only display specific files on your hard drive?

Something similar to the OpenFileDialog for win forms?
openFileDialog1.Filter = "Cursor Files|*.cur";

thanks,
Ron

Dear Sir and Madam,

I only change text on my Default.aspx file, but I must compiled project and upload all files in bin folder?

I use "Microsoft Visual Web Developer 2005 Express Edition".

It don't like asp.net 1.1

Is there any way I only upload the Default.aspx file?

Sorry for bad English.

Best Regards.

Since you are working with VS2005 it is most likely that you are using ASP.NET 2.0. In that case you con't have to copy everything, just the file that has changed.

Do you mean the cool web service in terms of the functionality or implementation? Or what else do you mean? Does Google bring up anything? Anyway, the link below can get you started:
