How to loop through cells of HTML table on a form

Hi,

How can I loop through an HTML Table and check all controls of each cell (TD) in it.

What I would like to achieve is make one TD on that table visible=true, and make all other TD visibility false.

Regads,
Blumen

Try this code. You will get all rows of HTML table.. then, check the tr variable at runtime, you will know how to get the cell value.

<br />
var tbody = document.getElementById("t1");<br />
 <br />
var i = 0;<br />
 for(i = 0; i < tbody.rows.length; i++){<br />
   var tr = tbody.rows[i];   <br />
 }

Thanks and Regards,

I've enabled script debugging in IE, but I can't debug in VS 2005 aspx file.

I'm not doing TBODY, instead I'm using this structure:

<table>
<tr>
<td></td></tr></table>

It's strange.. What about Firebug? See this article[^] if you are not so sure how to use Firebug.

OR

You can try to alert (eg. alert(tr.cell[0]);)

Normally, It is not possible... I think you probably need to use the third-party Ajax frameworks (e.g: AjaxPro and etc)...

For a new line break you can use this syntax in the inline code

DataBinder.Eval(Container.DataItem, "ColName").ToString().Replace(Environment.NewLine,"<br/>")

For a Hyperlink Column on the Gridview control, you can check the sample code Here[^]

I suggest you to take a look at the XmlReader and XmlWriter classes in .NET which will help you parse and write XML data from XML documents.

you can use a CommandField with ButtonType set as Image, ShowEditButton property set to True and EditImageUrl property to the appropriate Image. Write the relevant code on the RowEditing event of the GridView.

Create an instance of DateTimeFormatInfo class (System.Globalization) and specify the ShortDatePattern as 'dd/MM/yyyy' and then convert the string Date to the specified format using Date.Parse before checking it with IsDate() function.

You need to write something like this to handle the dateformat when it is 'dd/MM/yyyy'.

Dim DateFormat As New DateTimeFormatInfo
DateFormat.ShortDatePattern = "dd/MM/yyyy"
If IsDate(Date.Parse(DateString, DateFormat)) Then
  'your code
End If

I suggest you to write a common shared function which will take the string date in the format 'dd/MM/yyyy' and return the parsed Date. Then this function can be used whenever you need to do a Date conversion.

Return Date.Parse(DateString, DateFormat)
