How do I get the value of textbox in the datalist 20?

int sum=0;

for（int i = 0 ;i< -1;i++) assumes that the ID of the datalist is datalist1

textbox tb=(textbox)("Slag with tt"Suppose that the ID of the Senliang Number Candidate text box is set to TT when you design the DataList

sum+=;

That's the idea.

Use the findcontrol method to find the text box for each row of the datalist and sum it.

My program doesn't debug the syntax may be something not quite right, if there is a problem please hi me.

string tt=""

for(int i = 0; i < i++)textbox t = "textbox1"Textbox1 is the control ID, and the ID is unique.

tt=;Get the value.

If you want to get the value of another control, you can replace it directly.

textbox t = "textbox2"))label l = "label1"))

You need to find the textbox control in the datalist control first, and then assign it a value, give you 2 statements, and see for yourself, I use the textbox textbox1 = textbox) here"textbox1");It's to find the controls, so take a good look at it!!

You can use FindControls to find the name of the control, or you can iterate through all the controls in the datalist in if(

You can add an id to this text box, and if you want jquery, you can write $("#id").val(), the id in parentheses is the value of the id you defined.

Traverse over the element to get the corresponding item for the text.
