Hi,

I have a question about RadScriptManager.

When I create a RadScriptManager to use the RadAjaxManager,
This works well if generated directly from the "aspx". 

aspx :
...
<
body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadButton1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" UpdatePanelCssClass="" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
        </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>
    <telerik:RadButton ID="RadButton1" runat="server" OnClick="RadButton1_Click" Text="RadButton">
    </telerik:RadButton>
    <asp:Panel ID="Panel1" runat="server">
        <telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" Culture="ko-KR" Skin="Metro">
            <MasterTableView ClientDataKeyNames="itemcd" AllowAutomaticDeletes="False" AllowAutomaticInserts="False" AllowAutomaticUpdates="False" AutoGenerateColumns="False" DataKeyNames="itemcd" EditMode="Batch">
                <Columns>
                    <telerik:GridBoundColumn DataField="itemcd" FilterControlAltText="Filter itemcd column" HeaderText="품목코드" ReadOnly="True" SortExpression="itemcd" UniqueName="itemcd">
    <ColumnValidationSettings>
    <ModelErrorMessage Text=""></ModelErrorMessage>
    </ColumnValidationSettings>
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="itemnm" FilterControlAltText="Filter itemnm column" HeaderText="itemnm" SortExpression="itemnm" UniqueName="itemnm">
    <ColumnValidationSettings>
    <ModelErrorMessage Text=""></ModelErrorMessage>
    </ColumnValidationSettings>
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="size" FilterControlAltText="Filter size column" HeaderText="size" SortExpression="size" UniqueName="size">
    <ColumnValidationSettings>
    <ModelErrorMessage Text=""></ModelErrorMessage>
    </ColumnValidationSettings>
                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
            <ClientSettings AllowKeyboardNavigation="true">
 
                <Selecting CellSelectionMode="MultiColumn"></Selecting>
                <ClientEvents OnCellSelected="RadGrid1_OnCellSelected" OnCellDeselecting="RadGrid1_OnCellDeselecting" OnBatchEditCellValueChanging="RadGrid1_OnBatchEditCellValueChanging" />
            </ClientSettings>
        </telerik:RadGrid>
    </asp:Panel>
    <asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:DaeMyungDB %>"
        SelectCommand="SELECT top 1000 itemcd, itemnm, size FROM biitm01t"
        runat="server"></asp:SqlDataSource>
    </form>
</body>
...

However, I had to remove RadScriptManager from the aspx.
Then, When I add in cs this, RadAjaxManager does not work.

cs:
...
        protected void Page_Load(object sender, EventArgs e)
        {
            RadScriptManager scriptManager = new RadScriptManager();
 
            this.Form.Controls.Add(scriptManager);
        }
        protected void RadButton1_Click(object sender, EventArgs e)
        {
            RadGrid1.Rebind();
        }
...

What did I do wrong?

Thanks,
Yoongu.

Hello Yoongu,

Thank you for contacting us.

To achieve the desired functionality you need to use following code snippet:
protected RadScriptManager theManager;
 
    protected override void OnPreInit(EventArgs e)
    {
        theManager = new RadScriptManager();
        Page.Items[typeof(ScriptManager)] = theManager;
        base.OnPreInit(e);
    }
 
    protected override void OnLoad(EventArgs e)
    {
        Page.Items[typeof(ScriptManager)] = null;
        this.Form.Controls.AddAt(0, theManager);
 
        base.OnLoad(e);
    }

Additionally I am sending you a simple example. Please check it out and let me know if it helps you.

If you need further assistance, do not hesitate to contact us again.
