RowDataBound Event...

Introduction: 

In this article I will explain how to find controls (textbox, dropdownlist, checkbox,radio button etc..) in inside of gridview and how to get values from controls which is inside of gridview in rowdatabound condition in asp.net.
 
Description:

Generally if we want to find or get value from controls which is inside of gridview in rowdatabound condition we will write code like this
 

protected void gvUserInfo_RowDataBound(object sender, GridViewRowEventArgs e) { DropDownList ddl = (DropDownList)gvUserInfo.FindControl("yourControlName"); string ddlValue = ddl.SelectedItem.Value; TextBox txtUserInfo = (TextBox) gvUserInfo.FindControl("yourControlName"); string strValue = txtUserInfo.Text; }

Suppose if we have controls in each row of gridview then we need find each row of controls for that we need to write a code like this
 

protected void gvUserInfo_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { DropDownList ddl = (DropDownList)e.Row.FindControl("ddlCity"); int CountryId = Convert.ToInt32(ddl.SelectedItem); } }
