I am using a GridView on my ASP.NET form.
Would it be possible to have a GridView with 10 empty rows, having 5 columns.
Can I define the number of GridView Rows I could Edit.
i would then have an Update Button, which would update all the rows to the database.

I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

View 5 RepliesI have a gridview and i wanted to add a row when the gridview is empty, so that the header would be shown anyway. I have read about it on the web but i can't quite understand where exactly should i add the row.
My grid is binded by a sqldatasource. I am already adding a second header for the grid (to display some filters, and they need to be shown even if there are no results so that the user can perform another "search"), on rowCreated event, so, where am i supposed to add the row? Which events are fired even if the gridview is empty?
provide an example to do that... "Hide column if row is empty" in Databound()
datasource could be .1
coulmn: id-value1-value2-value3
row: 1-4-3-NULL (output: hides row value3) because the value is NULL
.2
coulmn: id-value1-value2-value3
row: 1-4-NULL-NULL (output: hides row value2,value3)

When retrieving values from Gridview empty cells, you will get " " instead of a empty string or null.
Someone once change the columne's properties as following, but it doesn't work
ConvertEmptyString > true
HtmlEncode > false
HtmlEncodeFormatString >false
One solution is to check if the cell value is " ". If so, assign it an empty string. But this approach looks awkward.
