Thread:  Convert String fields' value to UPPER


sekorev (User)   Posted on: 23-Jun-2008 10:11:38.
Hi,

Lets say that i have a car entity.

Code:

txtModel.Text = "Audi";
txtYear.Text = "1983";
txtSubject.Text = "this is An Info abouT the CAr. ";
CarEntity car = new CarEntity();

car.Model = txtModel.Text;
car.Year = txtYear.Text;
car.Info = txtSubject.Text ;

car.Save();


what i want to do is
whatever the inputs are
convert strings to uppercase before ( or just before) Save() function. ( And also i want to replace some characters like ö >> oe , ü >> ue in german ) is there an easy way to do?

After persisting object in db.
MODEL = "AUDI"
YEAR = "1983"
INFO = "THIS IS AN INFO ABOUT THE CAR"

i use SelfServicing model.

thank in advance

You could use one of those methods:


Code:

// this is called when a value is set
public partial class CarEntity
{
    protected override void PreProcessValueToSet(IEntityField2 fieldToSet, ref object valueToSet)
    {
        base.PreProcessValueToSet(fieldToSet, ref valueToSet);

        // set to UPPERCASE
        if (valueToSet != null)
        {
            if (fieldToSet.Name == CarFields.Model.Name || fieldToSet.Name == CarFields.Info.Name)
            {
                valueToSet = (string)((string)valueToSet).ToUpper();
            }
        }
    }
    
    
    // this is called right before the entity is saved
    protected override void OnBeforeEntitySave()
    {
        // set to UPPERCASE
        Model = Model.ToUpper();
        Info = Info.ToUpper();

        
        base.OnBeforeEntitySave();
    }
}

Hi goose,

I have nearly 60 entities, it is really hard to rewrite them by hand.
whenever an entity has string values, automatically convert to upper.
Is there any way to do it using templates or some other stuff?

Override PreProcessValueToSet in a partial class of CommonEntityBase Regular Smiley (that will take 1 override Regular Smiley)

Hi Otis,

i am too newbie to find it.

in the generated project CommonEntityBase.cs , within the class

protected override void PreProcessValueToSet()
        {

        }

Error    1    'light.EntityClasses.CommonEntityBase.PreProcessValueToSet()': no suitable method found to override    C:\Projects\lightNET\light\EntityClasses\CommonEntityBase.cs

i appreciate if you show.

It's a method in EntityBase/EntityBase2:
Code:

/// <summary>
/// Method which is meant to be overriden to pre-process a value right before it is set as a field's new value. In general you don't need to override
/// this method. By default it's a no-op.
/// </summary>
/// <param name="fieldToSet">The field to set.</param>
/// <param name="valueToSet">The value to set.</param>
protected virtual void PreProcessValueToSet( IEntityField2 fieldToSet, ref object valueToSet )
{
    // nothing
}


so you should be able to override it.
