View 2 RepliesI have a gridview which generate a link based on certain condition inside the Grid from code behind. What I want to achieve is when I click on that link, I want to catch all the information from the row that the link is in. So for example, if row 1, 2, and 4 has links in cell 5, When I click row 1's link, I want to get all the cell value from row 1. When I click on row 2's link, I want to get all the cell value from row 2, etc. I am somewhat close but not quite. When I click on row 2, I still get the same value from row 1, same as when I click on row 4, I get the same value from row In short, I want to get the row's value based on the link that's in the row. Here's my code:
$('a.SendEmail').click(function(e){
var Name = $('#<%=GridView2.ClientID%> td:eq(1)').text();
var Id = $('#<%=GridView2.ClientID%> td:eq(2)').text();

I am using visual studio 2008. I have a winforms app that takes data from an xml doc. I store the data in a ms sql database that I have created via a stored procedure. When Irun the app the data from the xml doc is captured and put in the database, but I can only see old data, the data that is captured during the current session can not be seen unless I close the app down and restart it. I have tried the following, and every variation I can think of to allow me to see the new data but to no avail.[code]
View 4 RepliesI load a 47,000 line Text file into a Datagridview, not a problem at all.
I would like to get the Distinct values for Column1. I have been scratching my head on how to do this, I have not as of yet found an easy way to do this,
Yesterday I attempted to add some code to turn one of the cells a different colour diring databinding method. When I added that code and debugged, my gridview stopped showing data.
So I took the entire method OUT...
Now my gridview does not display even when I put a STOP at the page load method, and it shows the gridview AND SQLDATASOURCE as having rows.
My gridview is showing more than one ProductName column and the ProductID column as well.All I want it to show is the Product Name clickable column.
