ASP. NET (2): bind the control data source in the init Method

Application scenarios:

Controls define an attribute as follows:Code

Public   Int ? Dimissionid
{
Get
{
If (Ddldimission. selectedvalue = Utility. dllshowdefaultvalue)
Return   Null ;
Else
Return   Int . Parse (ddldimission. selectedvalue );
}
Set
{
VaR Li = Ddldimission. Items. findbyvalue (value. tostring ());
If (Li ! =   Null )
Ddldimission. selectedvalue = Li. value;
}
}

 

If the following data source is processed in page_load, define the control and assign a value to the attribute. The expected result is not displayed on the page.

 

If ( ! Ispostback)
{
Utility. initdictionarybind < Dimissioninfo > (Ddldimission, Null );
}

 

However, in page_init, the call is normal.

Summary:

The custom attribute assignment process is executed only after the page_init function is executed.

Tip: Understand the page execution process.
