Prevent gridview retrieve on page load

[Guest]

Hi,

I have a form with textboxes, a search button and a gridview. The textboxes
are filled with default values so that the gridview should return all rows
but not before the user has had the chance to change some of the textboxes
and has clicked the search button.
How can I avoid the gridview displaying all rows before the search button
was clicked?
Any Ideas? Thanks
Diane

Thanks Eliyahu for your answer. I'm new in ASP(.net) probably that's why it
is not yet fully clear to me how to control databinding. I use an
objectdatasource with a tableadapter to populate my gridview. I presume this
is an 'automated' databind? How can I prevent it and trigger the databinding
when the search button is clicked?

Diane,

A gridview displays its content. If there is no content, there is nothing to
display. In most scenarios a gridview gets populated as a result of
databinding. Probably, you are calling DataBind method for the gridview or
for the page. In the latter case, replace a DataBind call for the page with
DataBind calls to specific components that need databinding. And call
DataBind for the grid in the event handler for the search button.

Sorry, but I can't see where to set the Datasource property.
When I click on my gridview I see a DataSourceID property but no DataSource
property.

I think, if you use DataSourceID property, the databinding will take place
automatically as your set the property. Instead use DataSource property.
Than you will have to call DataBind manually.

You can set it either in code-behind or in .aspx file in the Source view.
