How do I use a DropDownList in a Gridview Edit Template when the selected value does not mirror sql data?
You don't need to do this in code; the ListItem has both a Text and a Value property: <asp:DropDownList ID="ddlDay" runat="server" SelectedValue='<%# Bind("Day") %>'> <asp:ListItem Value="1" Text="Monday" /> <asp:ListItem Value="2" Text="Tuesday" /> <asp:ListItem Value="3" Text="Wednesday" /> <asp:ListItem Value="4" Text="Thursday" /> <asp:ListItem Value="5" Text="Friday" /> <asp:ListItem Value="6" Text="Saturday" /> <asp:ListItem Value="7" Text="Sunday" /> </asp:DropDownList> The SelectedValue will return the day number, and the list will display the day name.

Getting row of selected DropDownList in GridView cells
You can find the grid view row by finding the grandparent (.Parent.Parent) of your drop down list, because the drop down list is within a cell of the row, which is a part of the row itself, so you need to go two levels up, like this: protected void chooseThemeTypeDropDown_OnSelectedIndexChanged(object sender, EventArgs e) { DropDownList chooseThemeTypeDropDown = sender as DropDownList; if (chooseThemeTypeDropDown != null) { System.Diagnostics.Debug.WriteLine(chooseThemeTypeDropDown.SelectedItem.Value.ToString()); GridViewRow row = (GridViewRow)chooseThemeTypeDropDown.Parent.Parent; } }

filter gridview based on dropdownlist selected value
You are not showing where you initialize idTeacher. However, you have to DataBind the GridView in ASP.NET after you have assigned the DataSource: GridView1.DataSource = table; GridView1.DataBind(); // <-- this is missing in your code You should use sql-parameters anyway, otherwise you are potentially open for sql-injection and you should use the using statement to ensure that all unmanaged resources are disposed (even on error): using (var con = new OleDbConnection("ConnectionString")) using (var da = new OleDbDataAdapter("select * from teacher where idteacher=@idTeacher", con)) { da.SelectCommand.Parameters.AddWithValue("@idteacher", idTeacher); DataTable table = new DataTable(); da.Fill(table); // opening or closing connection not needed, done by Fill GridView1.D

How can I add a HyperLinkField to GridView databound to a file directory?
Instead of building the GridView manually, create a datasource that you can bind to. First create a custom class to hold the details: public class FileOrFolderDetail { public string Claim{get;set;} public string Name{get;set;} public string Link{get;set'} public string Application{get;set;} } Next, create a List of your new class: var fileOrFolderDetails = new List<FileOrFolderDetail>(); At that point, go through your two loops like you're doing, but create new FileOrFolderDetail objects and add them to the List. Finally, bind your GridView to fileOrFolderDetails, and set up your HyperLinkField in the ASPX to use Link as the DataNavigateUrl. Let's start there and we can tweak as necessary.

Programmatically change databound property in GridView ItemTemplate
Maybe I am not understanding fully but it seems like you should just make a separate TextBlock control and programatically hide/show each databound TextBlock when the button is clicked. EDIT: Found this answer to help with the visibility aspect (I dont have much XAML experience). If this can only be executed on a databinding event then maybe consider creating a global boolean ShowName and when the button is pressed toggle that boolean value then launch the databind event of the GridView. Then that event will check the booleans value and show/hide the correct TextBlock.

populating DropDownList in a gridview with array elements
You could simply loop it and add the ListItems programmatically: DropDownList drd = (DropDownList)GridView1.FindControl("DrdDatabase"); foreach(string colName in mylist) drd.Items.Add(new ListItem( colName )); However, are you sure that you find your DropDownList via GridView1.FindControl? I assume you get a NullRefernceException there. Then you need to show us where it actually is. If it is in a TemplateField of the GridView you should use the RowDataBound event: private ArrayList ExcelData { get { object excel = Session["exceldata"]; if (excel == null) Session["exceldata"] = new ArrayList(); return (ArrayList)Session["exceldata"]; } set { Session["exceldata"] = value; } } protected void GridView2_RowDataBound(object sender, GridVi

Cannot Access DropdownList in EditItemTemplate inside Gridview
The RowEditing event just gives the row index being edited. You need to set the edit row index to the grid and rebind it. And if you need to set a value or need to bind a control inside EditItemTemplate you have to do it in RowDateBound event, as you will be re-binding grid in RowEditing event so the RowDataBound event will also give you the EditItemTemplate's controls. As shown in this answer protected void gv_RowEditing(object sender, GridViewEditEventArgs e) { // grid view's edit index has been changed so rebind it gv.EditIndex = e.NewEditIndex; } protected void gv_RowDataBound(object sender, GridViewEditEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if ((e.Row.RowState & DataControlRowState.Edit) > 0) { ddList.SelectedValue
