Web Control Events

[Ahmzee]

Hi All,

I am developing webpart for Sharepoint Portal Server.Webparts inherit
webcontrol and are similar to web custom controls.

The problem i am faing is that if i create controls (LinkButtons) in
the CreateChildControls Method it's click event works perfactly.

But if i create controls (LinkButtons) in the RenderWebPart Method it's
click event doesn't work....WHY ?

the sequence in which the events are executing is debugged to be

1 - CreateChildControls
2 - Control's Event
3 - RenderWebPart

I came to know in the click event what UI to Create so i can't use
CreateChildControls as it has already been executed so i want to to do
it in RenderWebpart.

For creating controls / UI am calling the same function from both
CreateChildControls and RenderWebPart, but it doesn't work in the
later.

plz Help
Ahmzee.

You have to do these things in CreateChildControls.

Whenever something happens which invalidates the set of child controls, you
must set ChildControlsCreated to false. So, for instance, in your click
event, if you are going to change the UI, you have to set
ChildControlsCreated to false. This will cause CreateChildControls to be
executed the next time someone callse EnsureChildControls. At the worst,
this will happen just before PreRender.
