I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
[URL] im using above tutioral i have changed little bit first in Header1 i have dropdownlist on selecting that it cause postback then it bind some value from database to Header2 itemtemplate and Header3 itemtemplate label. on clicking add new row then it create new row if user selct again then it bind the values in two label what i need here is i need foter total for both Headerr2 and Header3 itemtemplate on footer template label.
I have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.
I have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense

I have created a custom control that implements Templates (based on Panel controls) ... I can do a FindControl to locate imbedded controls. This allows me to get and set values in the imbedded controls, but I want to be able to reference the imbedded controls like they are properties of the associated panel. Here is a sample of how my custom control now works:
I can do the following (where my custom control has given the panel hosting the template the name "myPanel"): Dim txt As TextBox = myCustomControl.myPanel.FindControl("myTextBox") txt.Text = "Some text to put in TextBox"
What I want to do is:
myCustomControl.myPanel.myTextBox.Text = "Some text to put in TextBox"
