Re: FormView Does not have public property linkbutton

You need to put your Insert- and CancelButton inside the ItemTemplate:

<asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource1"
            AllowPaging="True">
            <EditItemTemplate>
                FirstName:
                <asp:TextBox ID="FirstNameTextBox" runat="server"
                    Text='<%# Bind("FirstName") %>' />
                <br />
                LastName:
                <asp:TextBox ID="LastNameTextBox" runat="server"
                    Text='<%# Bind("LastName") %>' />
                <br />
                Title:
                <asp:TextBox ID="TitleTextBox" runat="server" Text='<%# Bind("Title") %>' />
                <br />
                <asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True"
                    CommandName="Update" Text="Update" />
                 <asp:LinkButton ID="UpdateCancelButton" runat="server"
                    CausesValidation="False" CommandName="Cancel" Text="Cancel" />
            </EditItemTemplate>
            <InsertItemTemplate>
                FirstName:
                <asp:TextBox ID="FirstNameTextBox" runat="server"
                    Text='<%# Bind("FirstName") %>' />
                <br />
                LastName:
                <asp:TextBox ID="LastNameTextBox" runat="server"

                 <asp:LinkButton ID="InsertCancelButton" runat="server"
                    CausesValidation="False" CommandName="Cancel" Text="Cancel" />
            </InsertItemTemplate>
            <ItemTemplate>
                FirstName:
                <asp:Label ID="FirstNameLabel" runat="server" Text='<%# Bind("FirstName") %>' />

                <br />
            <asp:linkbutton id="InsertButton"
                  text="Insert"
                  commandname="Insert"
                  runat="server" />
            <asp:linkbutton id="CancelButton"
                  text="Cancel"
                  commandname="Cancel"
                  runat="server" />
            </ItemTemplate>

        </asp:FormView>

Re: FormView Does not have public property linkbutton

Re: FormView Does not have public property linkbutton

what a dumb question i've asked before!!anyway i wrote services for linked button in script tag but cancel command is not working

it should be ideally cancel the insert if all the textboxes are not filled but it is taking incompeted input.

code is as below (this code is same as it is provided in online example.)

void employeeformview_ItemInserting(Object sender, FormViewInsertEventArgs e)
    {
        MessageLabel.Text = "";

        // Iterate through the items in the Values collection
        // and verify that the user entered a value for each
        // text box displayed in the insert item template. Cancel
        // the insert operation if the user left a text box empty.
        foreach (DictionaryEntry entry in e.Values)
        {
            if (entry.Value.Equals(""))
            {
                // Use the Cancel property to cancel the
                // insert operation.
                e.Cancel = true;

                MessageLabel.Text += "Please enter a value for the " +
                  entry.Key.ToString() + " field.<br/>";

            }
        }
    }

    void employeeformview_ModeChanged(Object sender, EventArgs e)
    {
        // Clear the MessageLabel Label control when the FormView
        // control changes modes.
        MessageLabel.Text = "";
    }

    </script>

Re: FormView Does not have public property linkbutton

So you mean the record gets inserted into the database despite there are some blank values?

Re: FormView Does not have public property linkbutton

yes they are getting inserted despite there are some blank values (and even though i've not specified NULL allow in table definition)

Re: FormView Does not have public property linkbutton

Set a breakpoint inside your employeeformview_ItemInserting event to find out if there are any blank values being posted.

Hello Truptir

As far as I seeI think you should generate CRUD methods for your FormView and enable InsertingUpdating and deletingThen when you choose to click "Insert"it should automatically change the mode state to Insert
