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

Question

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
