Hi,

Please post your asp.net question in the ASP.NET Forums in future.

DataList is populated as a DataListItemCollection. Each item in a DataList is a type of DataListItem object. You need to use FindControl method on DataListItem instead of DataList itself.

For example, To find control in the 4th item

TextBox txtAlias = (TextBox)DataList1.Items[3].FindControl("txtAlias");  //as index starts from 0

Hi,

See the below code to get TextBox from Datalist 

Method  1.

If you need to get all textbox from all row of datalist,

foreach (DataListItem dli in dataLst.Items)

            {

                TextBox cb = (TextBox)dli.FindControl("txtName");

            }

 

Method  2.

If you need to get textbox from current row (selected row) of datalist,

protected void dataLst_ItemCommand(object source, DataListCommandEventArgs e)

{

TextBox txtName = (TextBox)e.Item.FindControl("txtName");

}

Do let me know,if you need more details.
