    text
    copied!<p>So I have a country dropdownlist and a state dropdownlist which is being populated dynamically based off of the country chosen. When I click the country the state dropdown gets populated just fine but the problem arises when I click a value (state) from the other dropdown, the list instead of retaining the selected item will go back to the first item of the list and no selectedvalue are displayed.</p> <pre><code>&lt;td&gt;&lt;asp:DropDownList ID="ddlState" runat="server" DataSourceId="dsStateList" DataTextField="state_nm" DataValueField="state_cd" OnSelectedIndexChanged="ddlState_SelectedIndexChanged" AutoPostBack="true" AppendDataBoundItems="true" Width="160px" OnDataBound="ddlState_OnDataBound"&gt; &lt;/asp:DropDownList&gt; &lt;/td&gt; &lt;asp:DropDownList ID="ddlCountry" runat="server" DataSourceId="dsCountryList" DataTextField="COUNTRY_NAME" DataValueField="COUNTRY_CIA_ID" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged" OnDataBound="ddlCountry_OnDataBound" AutoPostBack="true" AppendDataBoundItems="true" Width="160px"&gt; &lt;/asp:DropDownList&gt; protected void ddlState_SelectedIndexChanged(object sender, EventArgs e) { string comboStateCODE = ddlState.SelectedValue; dsCompanyListParam.Text = comboStateCODE; ddlCountry.DataBind(); ddlState.DataBind(); } protected void ddlState_OnDataBound(object sender, EventArgs e) { ddlState.Items.Insert(0, "Please Select a State"); } protected void ddlCountry_SelectedIndexChanged(object sender, EventArgs e) { ddlState.Items.Clear(); dsStateList.SelectParameters["iCountryID"].DefaultValue = ddlCountry.SelectedValue; dsCompanyListParam.Text = ddlCountry.SelectedValue; Trace.Warn("ddlCountry_SelectedIndexChanged"); ddlCountry.DataBind(); ddlState.DataBind(); } protected void ddlCountry_OnDataBound(object sender, EventArgs e) { ddlCountry.Items.Insert(0, "Please Select a Country"); } </code></pre>
