I want to add a textbox in the header of a column and when keypress event on it is fired i need to use a function (not java) from my form. It must pass the textbox.text value to that fuction.I need it to make a search in the gridview.
I will want to add it in the filter and if i can take the event as StoreReadDataEventArgs . I
BOLDED the code in vb.net where i need to catch the parameter.
