What can be the best way to manage GridView <-> FormView <->

Terry

Hello,

In ASP.NET 4.5 using Entity Framework under WebForms app -

Show Data of selected row of GridView in FromView.

Change the Mode of FormView

Edit/Insert Data in Form View

Have Save button outside of Grid & Form views'. On click of Save button, want to call UpdateMethod of FormView that will validate, show errors in validation summary (if any) & finally save the data to db.

Using DataSource & Databind for FormView, my Item, Edit & Insert templates are working as expected. But with Save button, I am not able to call UpdateMethod - as for that I need to have SelectMethod in FormView.

If SelectMethod is set (removing Datasource & Databind part), the data is always blank.

I don't wish to write the validation part again & go this way :

public void inqFormView_UpdateItem(int id)

{

Inquiry item = null;

// Load the item here, e.g. item = MyDataLayer.Find(id);

if (item == null)

{

// The item wasn't found

ModelState.AddModelError("", String.Format("Item with id {0} was not found", id));

return;

}

TryUpdateModel(item);

if (ModelState.IsValid)

{

// Save changes here, e.g. MyDataLayer.SaveChanges();

}

Can you please suggest the best and suitable methodology for this situation ??

Any help is highly apprecited. Am stuck on this since last 3-4 days, and can't get a way for it. So please help me.

Thanks

Hello,

I got the answer of this query. Thought to share , as it might help some one searching the same like me.
In my FormView, have set SelectMethod, UpdateMethod, InsertMethod.
On GridView selectedIndexChanged event, I set the object for Form view & call DataBind() on FormView.
Finally, when user selects "Save" button (outside of Grid & Form view), I call formView.UpdateItem(true) ; which calls the UpdateMethod (that is set to name UpdateChannel) set in the FormView. And on passing true, I set it to validate the entity.
The same way I do for Inserting also, and this concept works great.

Thanks

Why you want a save button outside to do validation you can do that in grid view itself on typing and insert update and delete will also work with databind and data source
