I'm new to asp.net. I have an exercise about datagridview.
Basically it's like this, I created a sql database in visual studio, added some tables and records. I added a gridview to my page and change the datasource to 1 of my tables. It displays every thing fine.
Now my exercise is, I need to add a new record to that table from a textbox control and button submit, and display in gridview after page reload.
DataTable dt = new DataTable();
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

View 1 RepliesGeneral Info:Aspx page holds an Ascx User control. Inside the User control, the Repeater is contained inside a View, contained inside a Multiview.

Details:I have a repeater(inside an ascx user control) that shows records, and the first column is a checkbox. If checked, that row will be deleted.OUtside the repeater, I have a button that will deleted all rows that are checked.Everything works fine, but have been asked to add a pop up "confirm delete" message that includes the number of records that will be deleted if the user clicks "Ok" on the pop up.
Something like: "You are about to delete 8 records".

I have 3 pages, one to add a category, one to edit the category, and one to delete the category. The add and edit work fine. The delete is not working for some reason. I click the link on my site to delete it, and I'm just staring at the green bar in my browser taking a long time. The add and edit don't take long at all to perform their function. I'm thinking this is a connection string issue, but I don't see how it can be the case. It relies on web.config for it just like the other pages. Following is the delete page code behind and also delete cascade from the business logic area. After the page refreshes, I'm not getting any diagnostics or error messages which I have in the code. Doesn't this have to mean a db connection issue?
