DataBind on button click not working

[Michael]

I'm having trouble re- DataBinding a combobox on a button click event.  On the initial page load I'm binding the combobox (this works fine) which holds report settings.  I'm allowing the user to type in a value on the combobox which enables a save link button.  When the user clicks on the link button, I save all the report criteria off to the database and want to DataBind the combobox so show the newly added Item to the list.  I've debugged the process and show that the new item is getting saved off to the database,  the database is returning all items (including newly added).  It also appears that new item is getting bound to the combobox but it does not display in the browser.

Aspx:

                <table border="0" cellpadding="0" cellspacing="0" style="background-color:White;">
                <tr>
                    <td style="padding-right:5px;"><asp:LinkButton ID="lnkbtnSave" runat="server" Enabled="false" OnClick="lnkbtnSave_Click">Save</asp:LinkButton></td>
                    <td style="padding-right:5px;"><asp:LinkButton ID="lnkbtnSaveAs" Enabled="false" runat="server" OnClick="lnkbtnSave_Click">Save As...</asp:LinkButton></td>
                    <td><telerik:RadComboBox ID="rcbRptSettings" runat="server" AllowCustomText="true" EmptyMessage="My Reports" LoadingMessage="Loading..." OnSelectedIndexChanged="rcbRptSettings_SelectedIndexChanged" AutoPostBack="true" Skin="Outlook" Width="250px"></telerik:RadComboBox></td>
                    <td style="padding-left:5px;"><asp:LinkButton ID="lnkbtnDelete" runat="server" OnClientClick="return blockConfirm('Are you sure you want to delete this report?', event, 330, 100,'','AARates Delete My Report');" OnClick="lnkbtnDelete_Click" Enabled="false">Delete</asp:LinkButton></td>
                </tr>
                </table>

Code behind:

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

BindSavedSettings(Master.loggedUser.UserReports);

}

}

private void BindSavedSettings(List<UserReport> urReports)

{

rcbRptSettings.DataSource = urReports; //Master.loggedUser.UserReports;

rcbRptSettings.DataTextField = "Name";

rcbRptSettings.DataValueField = "UserReportID";

rcbRptSettings.DataBind();

rcbRptSettings.Items.Insert(0, new RadComboBoxItem("", ""));

}

protected void lnkbtnSave_Click(Object sender, EventArgs e)

{

//Saves existing report

bool settingsfound = false;

UserReport ursettings;

PgMessage.ClearMessages();

if (rcbRptSettings.Text != string.Empty)

{

//USED FOR GRID SETTINGS

//string grsettings = string.Empty;

//GridSettingsPersister persister = new GridSettingsPersister(ARGrid1);

//grsettings = persister.SaveSettings();

foreach (UserReport ur in Master.loggedUser.UserReports)

{

if (ur.Name == rcbRptSettings.Text)

{

settingsfound = true;

}

}

if (settingsfound)

{

ursettings = UserReport.getByKey(Convert.ToInt32(rcbRptSettings.SelectedValue));

SaveReportSettings(ursettings);

}

else

{                       //NEW Report Settings

ursettings = new UserReport();

SaveReportSettings(ursettings);

List<UserReport> urpt = UserReport.getByUserid(Master.loggedUser.Userid);

BindSavedSettings(urpt);  //BindSavedSettings to add new report setting

}

}

else

{

PgMessage.DisplayMessage(PageMessage.MessageType.Information, "Report Setting name must be entered");

}

}

I think I've figured this one out. The problem had to do with Ajax.  Once I set up the AjaxManagerProxy for the button to update the combobox everything worked.  I'm still trying to figure out the Ajax stuff. Seems that if a control is set up to update a second control, the second control has to be setup in AjaxManageProxy to effect any controls it my change in the code behind.

Hello Michael,

There is a subtle difference between RadAjaxManager and RadAjaxManagerProxy and you can read about each of these here and here.
