Access filter container from Page_Load

[Pau]

Hi,

I have a fully programmatically implemented Radgrid, with filters enabled. When you implement a Filter Template Class (to make a custom filter), you have to implement the function InstantiateIn, which has the container as a parameter. In this function you add the components of your Filter Template to this container, but I want to add controls to the container from outside this function. ​Is it possible to find this container form the Page_Load function? I've serached everything, and I have seen that you can get it at ItemCreated or ItemDataBound, I don't exactly remember. But this is not what I want, I want to get it from Page_Load. How can I do that?

 Thanks

Sorry I forgot to say that I only want to do this on postback, not at first time the page loads. I don't know if the grid is already there on postback or what.

 Thanks

Hello,

I am not sure about the exact implementation here but the filter controls should be initialized inside the GridFilterItem cells. That said you should be able to access the container using the following code.

C#:

TableCell cell = (RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem)[0] as GridFilteringItem)["TheColumnName"];

Have in mind that if the logic will be used inside the page load event you should ensure that the grid is already initialized.
