C# Find controls inside the controls

For finding controls inside the Panel you may use the "Controls" property. See this code:

foreach(Control ctrl in panel1.Controls)
{
  ctrl.Text = "Hello";
}

As the panel is inside the item template, it will be repeated for each row in grid view.

So first you have to take the row in which you want to change control's text.

e.g. GridViewRow gr = Gridview1.Rows[0];//taking the first row

Then you can find the panel as follows :

Panel tempPanel = (Panel)gr.FindControl("PanelID");

And then you may find the textbox inside the panel using

TextBox txt = (TextBox)tempPanel.FindControl("TextBoxID");

Or you may find this textbox directly inside the grid view row (if the textbox id is unique in the page) as follows:

TextBox txt = (TextBox)gr.FindControl("TextBoxID");


Now you can change the text of the control as : txt.Text = "New Value";


Hope this helps you !!
