Search for the Textbox Control in the gridview

1. Check the number of textbox columns in the gridview. Note:

The column in The gridview starts counting from 0, and the index in the first column is 0. add textbox to the first column, so we can

For (INT I = 0; I <this. gridview1.rows. Count; I ++)

{

Textbox TXT = (textbox) This. gridview1.rows [I]. cells [0]. findcontrol ("textbox1 ");

If (txt! = NULL)

{

String STR = TXT. Text; // The processing you want to do

}

}

2. assign values. Same as above

For (INT I = 0; I <this. gridview1.rows. Count; I ++)

{

Textbox TXT = (textbox) This. gridview1.rows [I]. cells [0]. findcontrol ("textbox1 ");

If (txt! = NULL)

{

TXT. Text = "the value you want to assign ";

}
