Hi guys, i'm working with on creating textbox at run time with lostfocus event. I generate variable of textbox in sub procedure GroupName with lostfocus event and second is lostfocus event to retrieve data from database and display it but the error is, if you declare the variable in first sub procedure, it will generate the set of textbox contineously in flowlayoutpanel but the variable cannot be use in second sub procedure. However, if you declare variable globally it will only generate set of textbox once flowlayoutpanel and stopped but you can reuse it in two or more subs to retrieve data from database... Please anyone with solution should kindly help me out

I'm not sure I get the gist of what's happening here. You shouldn't need to store the text box in a non-local variable if you just need it for an event handler. The first parameter of any event handler is the object that fired that event.

Thanks for looking to my problem. My problem is how to reuse txtTitle.text and txtMemoDescription.text in txtAccount1_Lostfocus event, bcus i wanted to call customer account to display name in txtTitle.text and txtMemoDescription.text. Meanwhile, GroupName is been called inside a button

But the issue here are; these two object are declare in Sub GroupName to generate at runtime. Therefore if you declare them globally it will generate the object in one row.

What i wanted is to generate set of TextBox and call (customer account) data from database to display them thank you.
