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);

}
