Well, I am a Visual Basic Developer.
C# or VB it does not matter, the major point is the idea, there are many tools and websites that enable you to convert code between two languages

Title: No Website Code RegisterClient

Abdulla thanks for the great article this was a great learning point. Unfortunetly I've been getting the following errors.

The ScriptManager.RegisterStartupScript line in "Public Overrides Sub Rendercontrol" method doesn't compile. I had to change it to "Page.ClientScript.RegisterClientScriptBlock"

This line in the onRowCreate "DirectCast(e.Row.FindControl("ChkHeader"), CheckBox).Attributes.Add("onclick", _
"ObjJs_" & Me.ID & ".CheckUnCheckRows(this.checked)")" produces an undefined object when the header checkbox is clicked. Have not been able to solve this one.

I also was unable to find the sample site in the download.

Hi there, I'm experiencing the same as Mouzam. There doesn"t appear to any Sample Website code files.

Has this issue been resolved yet?

I tried pasting in the error messages but the result is my previous post.

Hi, a nice simple article. But the SampleWebsite source is missing. I used this link to download (http://authors.aspalliance.com/AAbdelHaq/TestingCustomGridView.zip). CustomGrid source is available but SampleWebsite code is not.
