Template Fields control disappears on page postback

Hi ,

I am facing a strange problem while working gridview .Here is the problem description:

I am using a gridview which consist of boundfields and templatefields. templatefields contains some controls like check boxes and image. My gridview contains one template field at last colummn. My requirement is to add the N nnumber of boundfields before last templatefield at runtime. I have added the code something like this:

Grid.datasource=ds
grid.columns.insert(index,column)
grid.databind()

Now the gridview displays all the boundfields and tempaltefields(with controls added within it) along with the newly added boundfields. But the controls within templatefield disappears on page postback however newly added boundfields are displayed correctly.

I tried to disable the gridview viewstate and binded the grid on onInit/PreRender event of page in this case controls are visible but here faced some other problem. in this case the gridview.rows.count is zero and gridview rows are not readable.

Can anyone help me solving this strange problem.


Thanks
