how to set input field limit to 255

[Former Member]

When I enter more than 255 characters in a field and save, the backend only saves the first 255 characters. How do I limit my input field to only accept 255 characters?

thanks

Hi Anton,

Create a simple type of base tyep string.. In the simple type , specify the min and max length.

Change the value attribute datatype to this simpletype and map it to the input field.

Note : This does not affect the displayed UI length of the input field.

the user must not be able to type more than 255 characters.

Ie. the text edit must not allow more than 255 characters to be displayed when typing them in.

Hi,

Follow the procedure given by Bharathwaj ,

create a simple type with string as base type and specify max length to 255.

Change the value attribute datatype to this simpletype and bind it to the input field.

Once it is bound with the inputfield,you can enter only 255 chars in that input field.

More than that specified chars are not displayed in the input field.

You can specify smaller number to test the same.

Hope it helps

Hi Anton,

If you are talking about TextEdit then the display of that has to be controlled by the properties cols and rows.

And to restrict the input characters you can

1) first create a Simple Type Using dictionaries in the tree structure

2)switch to representation tab and there u can set the external length 255

3)create a context and select type--> set with corresponding data type

4)now bind your text edit property value with your context.

I still don't know what you mean by 'create simple type'.

pls elaborate giving steps.

I also don't see a representation tab.

Hi Anton,

For creating a simple type go to the dictionary in WD explorer.Over there in data types you get simple type and Structure option under the simple type you create it.

Hi Anton,

I got your point.But I dont think that keyboard events are incorporated in WD 7.0.

So i am not sure if this is possible.

Hi Anton,

Here you require to create a simple type which has the built-in type String and you can also set the minimum and the maximum length under the definition type.

If you enter more than 255 characters after setting the same as the maximum length the WDF will throw an error message for the same and the action will not be called.Does this suffice your requirement.
