    <p>I have a gridview to which I have created an Insert Template in the footer row.</p> <p>I have an ObjectDataSource which is bound to a business object.</p> <p>I have an OnInserting event handler which never gets fired.</p> <p>The program encounters an error once I call .Insert on the ObjectDataSource. The error I receive is that there are no values and that I should check to make sure the values dictionary is not empty.</p> <p>I do not see a way to insert with a dictionary as a parameter. I have seen mention of grabbing the ObjectDataSourceView and using it's Insert method but I do not see any mention of how to do that and MSDN claims you do not have access.</p> <p>Is reflection the way to go here? Is there a better way of having an insert row on a gridview? Am I missing something obvious in my steps here?</p> <p>Below is the code:<br/> ObjectDataSource:</p> <pre><code> &lt;asp:ObjectDataSource ID="LeasesDS" runat="server" OnInserting="LeasesDS_Inserting" DataObjectTypeName="CLS.BusObjects.LeaseObj" DeleteMethod="Delete" InsertMethod="Insert" OldValuesParameterFormatString="original_{0}" SelectMethod="GetLeasesByCustomerID" TypeName="CLS.BusObjects.LeaseObj" UpdateMethod="Update"&gt; &lt;SelectParameters&gt; &lt;asp:Parameter Name="customerID" Type="Int32" /&gt; &lt;/SelectParameters&gt; &lt;InsertParameters&gt; &lt;asp:Parameter Name="CustomerID" Type="Int32" /&gt; &lt;asp:Parameter Name="PurchaseDate" Type="DateTime" /&gt; &lt;asp:Parameter Name="AutoYear" Type="Int32" /&gt; &lt;asp:Parameter Name="Make" Type="String" /&gt; &lt;asp:Parameter Name="Model" Type="String" /&gt; &lt;asp:Parameter Name="LeaseEndDate" Type="DateTime" /&gt; &lt;/InsertParameters&gt; &lt;/asp:ObjectDataSource&gt; </code></pre> <p><br/> CodeBehind Methods:</p> <pre><code>protected void LeasesGrid_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "Insert" &amp;&amp; Page.IsValid) { LeasesDS.Insert(); } } protected void LeasesDS_Inserting(object sender, ObjectDataSourceMethodEventArgs e) { DropDownList GridCustomersList = (DropDownList)LeasesGrid.FooterRow.FindControl("GridCustomersList"); TextBox PurchaseDate = (TextBox)LeasesGrid.FooterRow.FindControl("PurchaseDate"); TextBox AutoYear = (TextBox)LeasesGrid.FooterRow.FindControl("AutoYear"); TextBox Make = (TextBox)LeasesGrid.FooterRow.FindControl("Make"); TextBox Model = (TextBox)LeasesGrid.FooterRow.FindControl("Model"); TextBox LeaseEndDate = (TextBox)LeasesGrid.FooterRow.FindControl("LeaseEndDate"); e.InputParameters["CustomerID"] = Convert.ToInt32(GridCustomersList.SelectedValue); DateTime? purchaseDate = null; if (!string.IsNullOrEmpty(PurchaseDate.Text)) purchaseDate = Convert.ToDateTime(PurchaseDate.Text); e.InputParameters["PurchaseDate"] = purchaseDate; int? autoYear = null; if (!string.IsNullOrEmpty(AutoYear.Text)) autoYear = Convert.ToInt32(AutoYear.Text); e.InputParameters["AutoYear"] = autoYear; string make = null; if (!string.IsNullOrEmpty(Make.Text)) make = Make.Text; e.InputParameters["Make"] = make; string model = null; if (!string.IsNullOrEmpty(Model.Text)) model = Model.Text; e.InputParameters["Model"] = model; DateTime? leaseEndDate = null; if (!string.IsNullOrEmpty(LeaseEndDate.Text)) leaseEndDate = Convert.ToDateTime(LeaseEndDate.Text); e.InputParameters["LeaseEndDate"] = leaseEndDate; } </code></pre>

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.

SQuiL has stopped working due to an internal error.

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