    <p>All,</p> <p>FYI: I am using VS2005, .net 2.0.</p> <p>I have a GridView control that exists in the FormView EditItemTemplate. Unfortunately, the GridView misbehaves in that setup, its DataKeys collection is empty when the page posts back and the select command of the gridview fires.</p> <p>Here is the sequence of events:</p> <ol> <li>User browses to the page</li> <li>User clicks 'edit' (FormView renders EditItemTemplate where the GridView is)</li> <li>The user clicks search which postbacks again and populates the GridView located in the EditItemTemplate (at this point the GridView has DataKeys)</li> <li>User selects item from GridView which raises row selected event</li> <li>On postback, the GridView RowCommand fires,- I check that the CommandName = "select" and run my code which throws exception because the DataKeys collection is empty at this point!</li> </ol> <p>One more additional detail: The GridView lives in a user control that resides in the EditItemTemplate of the FormView.</p> <p>NOTE:</p> <p>I was able to resolve this problem when I move my GridView out of the EditItemTemplate of the FormView,- now DataKeys collection is NOT empty. Unfortunately, the GridView has to be in the EditItemTemplate for the user to select clients he searched for.</p> <p>Any insight would be appreciated.</p> <p>Event handling code:</p> <pre><code>protected void ctlSearchResults_RowCommand(object sender, GridViewCommandEventArgs e) { // user has selected the client from the keyword search result list if (e.CommandName == "select") { GridView searchResultsGrid = (GridView)e.CommandSource; int selectedRowIndex = int.Parse((string)e.CommandArgument); int clientId = (int)searchResultsGrid.DataKeys[selectedRowIndex][Client.PROP_ENTITYID]; // raise Selected event _OnSelected(new ClientSelectedEventArgs(clientId)); } } </code></pre>

    2. COYes, I have added the event handling code to problem description. The index out of range exception happens on the line where I try to assign clientId by referencing the DataKeys collection. DataKeys collection size at this point is zero.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
