Gridview and Dynamically making a hyperlink....

I populate a dataset and bind it to a gridview...
grd1.DataSource = dsXXX
grd1.DataBind()

Then within the RowDataBound event I try to make a field within a specific column a hyperlink by using the following code....

Dim hLink As HyperLink = TryCast(e.Row.Cells(2).Controls(0), HyperLink)
hLink.NavigateUrl = "Profile.aspx?q=" + e.Row.Cells(2).Text

Unfortunatly I receive the following error:

"Specified argument was out of the range of valid values. Parameter name: index"

Can anyone help me make a hyperlink when dynamically binding a dataset?
Thanks!

Hi,

That error basically means that you are specifying an integer value for a Cell() that doesn't exist. In other words, there aren't as many cells as the code wants to get data from. Keep in mind that the Cells() collection is a 0-based index, so if you have a total of 15 cells, you would have to get data from Cells(0) to Cells(14). Trying to get something from Cells(15) would generate this type of error.

Make a hyperlink out of what? What control type is currently in Cells(2)? A Label?

Read the first line....gridview

You are trying to cast the first control in the third column of a row in your GridView into a HyperLink. So, I ask you what control type is currently in that position and your answer is GridView? That doesn't make sense.

Try changing this

Dim hLink As HyperLink = TryCast(e.Row.Cells(2).Controls(0), HyperLink)
hLink.NavigateUrl = "Profile.aspx?q=" + e.Row.Cells(2).Text

to

Dim hLink As New HyperLink
hLink.NavigateUrl = "Profile.aspx?q=" + e.Row.Cells(2).Text
hLink.Text = e.Row.Cells(2).Text
e.Row.Cells(2).Controls.Add(hLink)
