I am able to show listings. <code>it should show the country selected as that was in label</code>.</p> <p>I have tried with this but dropdownlist is filled with <code>System.Row.DataRowView</code> also it is not set at SelectedValue given as <code>cvalue</code></p> <p>aspx page</p> <pre><code>&lt;asp:TemplateField HeaderText="Country"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblCountry" runat="server" Text='&lt;%#Bind("Country")%&gt;'&gt;&lt;/asp:Label&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;asp:DropDownList ID="ddlCCountry" runat="server" Height="21px" Style="margin-left: 0px" Width="194px"&gt; &lt;asp:ListItem Value="-1"&gt;Select..&lt;/asp:ListItem&gt; &lt;asp:ListItem Value="af"&gt;Afghanistan&lt;/asp:ListItem&gt; &lt;asp:ListItem Value="ax"&gt;Aland Islands&lt;/asp:ListItem&gt; &lt;asp:ListItem Value="al"&gt;Albania&lt;/asp:ListItem&gt; &lt;/asp:DropDownList&gt; &lt;EditItemTemplate&gt; </code></pre> <p>.cs file</p> <pre><code> void gvhoteldetail_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowState == DataControlRowState.Edit) { string cnm="",cvalue=""; string getCountry = "Select * from tbl_countrynames where `Name`='" + cname + "'"; string getCountrynames = "Select * from tbl_countrynames"; MySqlConnection con = new MySqlConnection(connection); MySqlCommand cmd1 = new MySqlCommand(getCountrynames, con); DataSet ds1 = new DataSet(); MySqlDataAdapter da1 = new MySqlDataAdapter(cmd1); da1.Fill(ds1); MySqlCommand cmd = new MySqlCommand(getCountry, con); DataSet ds = new DataSet(); MySqlDataAdapter da = new MySqlDataAdapter(cmd); da.Fill(ds); if (ds.Tables[0].Rows.Count &gt; 0) { cnm = ds.Tables[0].Rows[0]["Name"].ToString(); cvalue = ds.Tables[0].Rows[0]["Value"].ToString(); } DropDownList ddlcountry = (DropDownList)e.Row.FindControl("ddlCCountry"); ddlcountry.DataSource = ds1; ddlcountry.SelectedValue = cvalue; ddlcountry.DataBind(); } </code></pre> <p>What could be wrong?</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
