更改SharePoint 2010自定义Newform.aspx中字段的“必需”属性

Question

I have created a custom newform.aspx by cloning the form generated by SharePoint Designer and added it to a VS2010 project. Everything seems to be working fine like setting the value etc... but I couldn't figure out how to set the Required property of a field.

Based on a certain condition I would like to set the required property of a field to true or false.

I am accessing the controls using CompositeField and BaseFieldControl but they dont seem to give a handle to set required property value.

Any pointers are greatly appreciated.

Answer 1

您可以设置AllowBlank内物品的属性（如TextField的）的CompositeField至真/假。

Answer 2

通过抓住以下属性而不是进入控件来设法找到解决方案。

objListFormWebPart.ItemContext.Fields["fieldDisplayName"].Required = false;
