Concatenation in html 2

[Zarcom]

I may be just overtired here but I thought this would be cool. I am making a link on a datagrid based on some static text (the page itself) and some dynamic text (the query string). I do realize the ways normally used to do this.
A select button and a redirect in the selectedindex change event.

Building the link on the item created event.
and I am sure there are others.

Just because I like to be difficult I thought of doing it this way. Use the Link Column type, add the static text in and concatenate the dynamic text on the end. However, I don't know how to do the concatenate bit in the HTML.
This is what I have so far,
<asp:HyperLinkColumn DataTextField=&quot;CampName&quot; NavigateUrl=&quot;SiteSelection.aspx?Camp=&quot; <%# DataBinder.Eval(Container, &quot;DataItem.CampName&quot %>></asp:HyperLinkColumn>

if anyone has suggestions such as go to bed and use a different method tomorrow I'll accept them. Thanks all. That'l do donkey, that'l do

Hi Mark,

I'm assuming that this doesn't give an error, but it never gets the camp name in the querystring? If so, you probably just need to move your quotation mark to after the code-closing tag (%>).

The new line would look like this (note the quotes in red):

<asp:HyperLinkColumn DataTextField=&quot;CampName&quot; NavigateUrl=&quot;SiteSelection.aspx?Camp=<%# DataBinder.Eval(Container, &quot;DataItem.CampName&quot %>&quot;></asp:HyperLinkColumn>

Hope this helps. If I am misunderstanding the questions, kick me in the tail a few times to clear my head.

gah!! why don't you kick me a few times that was so simple!
In that it makes perfect sense however, I do get an error with either my old stuff or the stuff you have.
Parser Error Message: Literal content ('<asp:HyperLinkColumn DataTextField=&quot;CampName&quot; NavigateUrl=&quot;SiteSelection.aspx?Camp=') is not allowed within a 'System.Web.UI.WebControls.DataGridColumnCollection'.

That is the error I am getting I thought it might be cause of the double quotes but a double double quote which is a string quote rather than a termination doesn't help either. So I am really not sure what it is.
Any other suggestions? That'l do donkey, that'l do

Concatenate inside your databinding expression.

NavigateUrl=&quot; <%# &quot;SiteSelection.aspx?Camp=&quot; & DataBinder.Eval(Container, &quot;DataItem.CampName&quot %>&quot;>

Same error but thanks. I think I may just do this another way. Just thought this would be better if it worked.

That is unless someone has some magic code? hmm do you? That'l do donkey, that'l do

Okay. . . turned out to be an interesting problem. However, there is a way (this I thoroughly tested it, instead of naively wishing for the moving of the quote sign to fix it).

In order to do what you want to do, you can use the following code:

<asp:HyperLinkColumn DataTextField=&quot;CampName&quot; DataNavigateUrlField=&quot;CampName&quot; DataNavigateUrlFormatString=&quot;SiteSelection.aspx?Camp={0}&quot;></asp:HyperLinkColumn>

The DataNavigateUrlField sets up the datafield to bind to the navigation URL, which is then used in the DataNavigateURLFormatString. . . by substituting {0} with the data value.

Hope this helps!
