    <ej:Button ID="CheckButton" Type="Button" ClientSideOnClick="showInDialog" Text="Spell Check using Dialog" runat="server"></ej:Button>
    <ej:SpellCheck ID="SpellCheck" ClientIDMode="Static" runat="server" ControlsToValidate="#TextArea">
        <DictionarySettings DictionaryUrl="../api/SpellCheck/CheckWords" CustomDictionaryUrl="../api/SpellCheck/AddToDictionary" />
    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInDialog() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.showInDialog();
            }
    </script>

    Handling Dialog Actions

    To define the specific actions before the dialog window open, the client-side event DialogBeforeOpen can be used as depicted in the below code example.

  • html
  • <div id="TextArea" contenteditable="true">

    <ej:SpellCheck ID="SpellCheck" ClientIDMode="Static" runat="server" ControlsToValidate="#TextArea" DialogBeforeOpen="onDialogBeforeOpen">
        <DictionarySettings DictionaryUrl="../api/SpellCheck/CheckWords" CustomDictionaryUrl="../api/SpellCheck/AddToDictionary" />
    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInDialog() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.showInDialog();
            }
            function onDialogBeforeOpen(args) {
                if (args.requestType == "dialogBeforeOpen") {
                    alert("dialog before open event triggered");
                }
            }
    </script>

    The client-side event DialogOpen can be used to define the specific actions after the dialog window open as shown in the following code example.

  • html
  • <div id="TextArea" contenteditable="true">

    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInDialog() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.showInDialog();
            }
            function onDialogOpen(args) {
                if (args.requestType == "dialogOpen") {
                    alert(args.targetText);
                }
            }
    </script>

    The following code example used to define some actions after the dialog closing by using the client-side event DialogClose.

  • html
  • <div id="TextArea" contenteditable="true">

    <ej:Button ID="CheckButton" Type="Button" ClientSideOnClick="showInDialog" Text="Spell Check using Dialog" runat="server"></ej:Button>
    <ej:SpellCheck ID="SpellCheck" ClientIDMode="Static" runat="server" ControlsToValidate="#TextArea" DialogClose="onDialogClose">
        <DictionarySettings DictionaryUrl="../api/SpellCheck/CheckWords" CustomDictionaryUrl="../api/SpellCheck/AddToDictionary" />
    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInDialog() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.showInDialog();
            }
            function onDialogClose(args) {
                if (args.requestType == "dialogClose") {
                    alert(args.updatedText);
                }
            }
    </script>

    It is possible to predict the error word details before starting the spell check operations through dialog mode by using the client-side event Start. The below code example describes the above behavior.

  • html
  • <div id="TextArea" contenteditable="true">

    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInDialog() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.showInDialog();
            }
            function onSpellCheckStart(args) {
                if (args.requestType == "spellCheckDialog") {
                    alert(JSON.stringify(args.errorWords));
                }
            }
    </script>

    You can get the corrected text content details before updating it into target element with the help of the client side event Complete as mentioned in the below code example.

                spellObj.showInDialog();
            }
            function onSpellCheckComplete(args) {
                if (args.requestType == "changeErrorWord") {
                    alert(args.targetText);
                }
            }
    </script>

        <ContextMenuSettings Enable="true"/>
    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInContextMenu() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.validate();
            }
    </script>

    NOTE

                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.validate();
            }
    </script>

    NOTE

    The ID given for the custom menu items must be unique.

    Handling Menu Actions

    The client-side event ContextClick can be used to define specific actions when a click made on the custom menu items. The following code example describes the above behavior.

  • html

                <ej:SpellContextMenuItem ID="IgnoreAll" Text="IgnoreAll" />
                <ej:SpellContextMenuItem ID="AddToDictionary" Text="Add to Dictionary" />
            </MenuItems>                  
        </ContextMenuSettings>
    </ej:SpellCheck>
    
    <script type="text/javascript">
            function showInContextMenu() {
                var spellObj = $("#SpellCheck").data("ejSpellCheck");
                spellObj.validate();
            }
            function onCustomMenuClick(args) {
                if (args.selectedOption == "Ignore") {
                    alert("Custom menu clicked");
                }
            }
    </script>

    It is possible to predict the target (error word) on which the right click is made with the use of the event ContextOpen. The below code example shows how to block the display of context menu, when right clicked on the word by setting args.cancel as true.

                spellObj.validate();
            }
            function onBeforeOpen(args) {
                if (args.selectedErrorWord == "Bluetec") {
                    args.cancel = true;
                }
            }
    </script>

    You can get the current spell check operation arguments details with the client-side event Validating. The following code example describes the way to block the ignoreAll operation for the particular word.
