Hidden Field and preset Value causes error

[Bubu]

Hi guys,

have the following code in my asp.net (dotNet 4.0) page:

<ext:Hidden ID="field_Hidden" runat="server" Value="anyValue" />

and get that Error in the Browser:

Parser Error Message: Cannot create an object of type 'System.Object' from its string representation 'anyValue' for the 'Value' property.

It should be possible to set an initial value within the tags.

Best regards,

Frank

Please use the .Text property, instead of .Value.

As well, please ensure you wrap your code samples in [CODE] tags.

Hope this helps.

Thanks mate,

that helped. Sorry for forgetting the Code Tags.
But I'm still wondering why the VALUE attribut is an object.

But I'm still wondering why the VALUE attribut is an object.

.Value is an Object because it's a common property of the parent Field type. Within each child type of Field (such as TextField, NumberField, etc) the .Value is treated differently. Some cases it's String, others an Int32, DateTime, Boolean, etc.

.Value is a common property, and what value is actually being held in .Value differs depending on the Field type.

The ASP.NET Parser cannot properly parse .Value properties if configured in markup. The .Value property shouldn't actually show up in markup Intellisense, so I'll double check that it isn't, and fix if it is.
