>>>>>>>>>>>On the same page I have a GridView bound to a dataset. Below the GridView there is a textbox (or several textboxes). As user navigates through the GridView (clicking on this or that row) I want the value/text in the textbox(s) to be updated according to new row in the dataset. My understanding is I need to bind the textbox(s) to the same dataset. How do you do it? An example, of one textbox binding to the dataset would be very helpful.

The only thing I don't know - yet - if the page has to be reposted on the call to this method. If so I will look for way to do it with jQuery so there is no reposting of the page and no trip back to the server.

then script on the page:

 function selectRow(i) {

function selectRow(i) {

TBH, when I need this type of functionality now I use WebAPI and angular. angular gives you a nice MVVM two-way binding on the client.

>I understand that 'this' is the object passed to the jQuery function() but I can't seem to figure how to use what is inside the Find() function. So far all I get is a bunch of empty strings (for each value in the pair). And I am not sure if the use of 'closest' is correct.

Can you post the link for that code so that I can see it in context. Ta
