How to declare an Edit box

Edit boxes provide a convenient means for users to enter text within a control on a ribbon tab. They are declared in DAML using the editBox element within the controls container.

An Edit box is declared using the id, className, and sizeString attributes. It can be configured to appear with or without a caption. Use the smallImage attribute to have an image displayed with the control. The image is positioned to the left of any caption.

The sizeString attribute is used to establish the width of the control. This string is representative of the kind of input that appears in the control. The sizeString attribute can also be updated at runtime.

The Edit box is referenced on a group using the editBox control with the refID attribute.

<groups>
   <group id="esri_domainview_filterGroup" caption="Filter">
      <editBox refID="esri_domainview_filterEditBox" size="medium"/>
   </group>
</groups>

<controls>    
   <editBox id="esri_domainview_filterEditBox" caption="Filter Text:" keytip="F" className="ArcGIS.Desktop.Internal.Mapping.DesignView.FilterDomainsEditBox" disableIfBusy="false" sizeString="1234567890123456789012" condition="esri_mapping_domainsPane">
      <tooltip heading="">Type filter text.<disabledText></disabledText></tooltip>
   </editBox>
</controls>    

The className attribute references the Edit box implementation. This is a class that inherits from the ArcGIS.Desktop.Framework.Contracts.EditBox base class.

internal class FilterDomainsEditBox : ArcGIS.Desktop.Framework.Contracts.EditBox
{
   public FilterDomainsEditBox()
   {
      Text = "";
   }
}

Control the enabled state of an Edit box using a condition

Use the condition attribute to assign a predefined condition. For more information about defining states and conditions within DAML, see that section.

<editBox id="esri_domainview_filterEditBox" caption="Filter Text:" keytip="F" className="ArcGIS.Desktop.Internal.Mapping.DesignView.FilterDomainsEditBox" disableIfBusy="false" sizeString="1234567890123456789012" condition="esri_mapping_domainsPane">
   <tooltip heading="">Type filter text.<disabledText></disabledText></tooltip>
</editBox>

Restricting entered text to a particular data type

The editBox control provides a dataType attribute that allows the control to restrict the text entered by the user. The default value is string.

Allow integers only

<editBox id="MyCustomEditBox" caption="Filter Text:" className="MyEditBox" disableIfBusy="false"
                 smallImage="Images\GenericButtonBlue16.png" dataType="int64"
                 sizeString="1234" >
   <tooltip heading="">
      Type filter text.<disabledText></disabledText>
   </tooltip>
</editBox>

Allow double only

<editBox id="MyCustomEditBox" caption="Filter Text:" className="MyEditBox" disableIfBusy="false"
                 smallImage="Images\GenericButtonBlue16.png" dataType="double"
                 sizeString="1234" >
   <tooltip heading="">
      Type filter text.<disabledText></disabledText>
   </tooltip>
</editBox>

Allow all input

<editBox id="MyCustomEditBox" caption="Filter Text:" className="MyEditBox" disableIfBusy="false"
                 smallImage="Images\GenericButtonBlue16.png" dataType="string"
                 sizeString="123456789" >
   <tooltip heading="">
       Type filter text.<disabledText></disabledText>
   </tooltip>
</editBox>

Setting the initial value

In the constructor of your Edit box class use the Text runtime property to set the initial value.

internal class MyEditBox : ArcGIS.Desktop.Framework.Contracts.EditBox
{
  public MyEditBox()
  {
    Text = "";
  }
}

Providing validation

The base ArcGIS.Desktop.Framework.Contracts.EditBox class provides OnEnter and OnTextChange methods that can be overridden by your implemented class to provide validation and/or custom action when the user enters text into the Edit box. See the code snippets below for how this looks.

<groups>
   <group id="esri_domainview_filterGroup" caption="Filter">
      <editBox refID="MyCustomEditBox" size="medium"/>
   </group>
</groups>

<controls>  
   <editBox id="MyCustomEditBox" caption="Filter Text:" className="MyEditBox" disableIfBusy="false"
                 smallImage="Images\GenericButtonBlue16.png" dataType="string"
                 sizeString="1234678901234567890" >
      <tooltip heading="">
            Type filter text.<disabledText></disabledText>
      </tooltip>
   </editBox>
</controls>

internal class MyEditBox :  ArcGIS.Desktop.Framework.Contracts.EditBox
{
  public MyEditBox()
  {
    Text = "";
  }

  protected override void OnEnter()
  {
    // TODO - add specific validation code here 
  }

  protected override void OnTextChange(string text)
  {
    // TODO - add specific validation code here
  }
}
