Hi,
I have a Gridview which contain the 2 columns first column is textbox: ID and second column is the Label for Name. Initially I am loading data into the Gridview from database and the Textbox for ID is in editable mode only. With one save button click I am updating all rows into database.
And one Add button which is outside the Gridview. When the user clicks on the Add I am inserting row to the Gridview. The user enter some value into the textbox ID I need to validate the ID entered If the ID is valid I need to populate the Correspoing name into Name label.
1)Which event I need to fire for Gridview to validate the TextBox entry, Textbox focus lost I need to check the entered ID.
2)If the user changes the ID of the row which Gridview got from Database. Here also I need to validate the Id and populate name for the corresponding ID.
Here my question is which I need to fire for Gridview which need to be fired for the ID text box loosing the focus.
Thanks in advance

AFAIK, there is only javascript event that can be fired after loosing the focus. So, if your validation function is a server-side function, you can't invoke this from client-script unless you are using Ajax.
So, I think that the sample way would be validating the input when the user click "Add" button instead of checking after loosing the focus......
It is just my idea. We can listen what other members say about that..

This can be achieved using Regular Expressions. Check the documentation for Regex class. Before showing results on your ASPX page, you should pass the result to a function where regular expressions are used to find the search keyword in the result text. Now replace the match with your color tag. May be something like <font color="HighlightColor"> + Placematchtext here + </font>

helloo all...,
i want to ask about item command in form view...
if i use item command in repeater, the code is:
Protected Sub Repeater1_ItemCommand(ByVal source As Object, ByVal e System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles Repeater1.ItemCommand
kode = CType(Repeater1.Items(e.Item.ItemIndex).FindControl("Kode"), Label).Text
End Sub
if i use item command in datalist, the code is:
Protected Sub DataList1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles DataList1.ItemCommand
kode = CType(DataList1.Items(e.Item.ItemIndex).FindControl("kode"), Label).Text
End Sub
it seems the item command of repeater and datalist are same...
but in formview is different.. the item command of repeater and datalist can not write in formview...

Have you tried a name that doesn't start with _, and making it case correct ? I realise VB is not case sensitive ( because it sucks ), but it's worth fixing that and seeing if the prefix makes a difference.
However, I'd imagine that the problem is most likely that because your pages do not use namespaces, a namespace is being invented for them, and they are not the same. Try putting both pages into the same namespace, or in namespaces you explicitly scope.
And consider finding a better teacher.

Best way is by checking the source of your aspx page.
go to view source and check the control and also check if it is a chid of anyone and see its id then use that add in your javascript and also see in what way they have given the id

Are you in a class that's been told to do this ? It's been asked a lot today
Store them with non standard filenames which you generate in your file system. Store these file paths, the original filenames and any other metadata in your database.
