    <p>I'm trying to subclass the .NET 2.0 Gridview control and implement a custom Update to perform when "edit" is clicked; however I get the following cryptic error message: "An unexpected error has occurred." I'm trying to access our db logs to see if its failing there, but until i get access, i cannot debug the issue. Here are snippets of my code:</p> <p>In the WebPart CreateChildControls method:</p> <pre><code>sqlDataSource.UpdateCommand = "dbo.UpdateInvoiceData"; sqlDataSource.UpdateCommandType = SqlDataSourceCommandType.StoredProcedure; sqlDataSource.UpdateParameters.Add(new Parameter("month", DbType.Int32, "2")); sqlDataSource.UpdateParameters.Add(new Parameter("year", DbType.Int32, "2010")); this.Controls.Add(sqlDataSource); EditGridView edv = new EditGridView(sqlDataSource); this.Controls.Add(edv); </code></pre> <p>In the EditGridView webcontrol:</p> <p>OnLoad:</p> <pre><code>this.AutoGenerateEditButton = true; this.AutoGenerateColumns = true; string[] keyNames = { "Name" }; this.DataKeyNames = keyNames; this.EnableViewState = true; this.DataSourceID = sqlDataSource.ID; this.DataBind(); </code></pre> <hr> <pre><code>protected override void OnRowUpdating(GridViewUpdateEventArgs e) { try { sqlDataSource.UpdateParameters.Add(new Parameter("ExtraParamName", DbType.Int32, e.NewValues["ExtraParamName"].ToString())); sqlDataSource.UpdateParameters.Add(new Parameter("Name", DbType.String, e.NewValues["Name"].ToString())); sqlDataSource.UpdateParameters.Add(new Parameter("spUser", DbType.String, "test")); } catch (Exception ex) { this.Page.Response.Write("Error occurred while updating the record. " + ex.Message); } } </code></pre>

    1. CONikkia, in order to figure out what the error is, you can modify the web.config so that instead of the "An unexpected error" page you get a stack trace. See here: http://blog.thekid.me.uk/archive/2007/02/15/a-solution-to-quot-an-unexpected-error-has-occurred-quot-in-wss-v3.aspx

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
