problem is displaying values in html select control

[cmrhema]

Hi,

I have two controls one html select control and one asp.net dropdownlist control.

In html select control i have three maps loaded. It is loaded in the following manner.

<SELECT class="TextBoxLabel" id="ddlMap" style="WIDTH: 128px;" tabIndex="1" onchange="fnChangeMap();"
 
name="ddlMap" runat="server">
 
 
</SELECT>
 
 
 
function fnChangeMap()
 
{ 
 
if(document.frmLiveTrack.ddlMap.value != 0){
 
var vMap = document.frmLiveTrack.ddlMap.value;
 
var vMapValues = vMap.split(",");
 
for(i=0 ; i < vMapValues.length ; i=i+5)
 
{
 
document.mapping.country.value = vMapValues[i];
 
document.frmLiveTrack.country.value = vMapValues[i];
 
document.frmLiveTrack.country1.value = vMapValues[i];
 
document.mapping.Lat.value = vMapValues[i+1];
 
document.mapping.Lon.value = vMapValues[i+2];
 
document.mapping.scale.value = vMapValues[i+3];
 
document.frmLiveTrack.DefaultURL.value = vMapValues[i+4];
 
}
 
//alert(document.frmLiveTrack.DefaultURL.value);
 
document.mapping.target = "MainFrame";
 
document.mapping.method = "get";
 
document.mapping.action = document.frmLiveTrack.DefaultURL.value; 
 
document.mapping.submit(); 
 
}
 
else{
 
alert("Select a Map");
 
}
 
}
 
 
 
Further i have a function called as load map which is called in page load event
 
private void LoadMap(string strUserId, int iUserType)
 
{
 
this.loadmapval = "Dhanus";
 
string text1 = "";
 
DataSet set1 = new DataSet();
 
ConnectionCls cls1 = new ConnectionCls();
 
text1 = TrackQuery.getMapQry(strUserId, iUserType);
 
set1 = cls1.dsGetValues(text1);
 
string text2 = base.Request.Params["country"];
 
if (iUserType == 1)
 
{
 
this.ddlMap.Visible = true;
 
this.lblCountry.Visible = false;
 
if (set1.Tables[0].Rows.Count > 0)
 
{
 
for (int num1 = 0; num1 < set1.Tables[0].Rows.Count; num1++)
 
{
 
DataRow row1 = set1.Tables[0].Rows[num1];
 
string text3 = Convert.ToString(row1["MAPNAME"]);
 
text3 = text3 + "," + Convert.ToString(row1["MAPLAT"]);
 
text3 = text3 + "," + Convert.ToString(row1["MAPLONG"]);
 
text3 = text3 + "," + Convert.ToString(row1["MAPSCALE"]);
 
string text7 = text3;
 
text3 = text7 + "," + Convert.ToString(row1["MAP_URL"]) + "/" + Convert.ToString(row1["ENGINE_DEFAULT_URL"]);
 
if (text2.Equals(Convert.ToString(row1["MAPNAME"])))
 
{
 
this.strMapDetail = text3;
 
}
 
this.ddlMap.Items.Add(new ListItem(row1["MAPNAME"].ToString(), text3));
 
}
 
}
 
}
 
else if (iUserType == 2)
 
{
 
this.ddlMap.Visible = true;
 
this.lblCountry.Visible = false;
 
if (set1.Tables[0].Rows.Count > 0)
 
{
 
for (int num2 = 0; num2 < set1.Tables[0].Rows.Count; num2++)
 
{
 
DataRow row2 = set1.Tables[0].Rows[num2];
 
string text4 = Convert.ToString(row2["MAPNAME"]);
 
text4 = text4 + "," + Convert.ToString(row2["MAPLAT"]);
 
text4 = text4 + "," + Convert.ToString(row2["MAPLONG"]);
 
text4 = text4 + "," + Convert.ToString(row2["MAPSCALE"]);
 
string text8 = text4;
 
text4 = text8 + "," + Convert.ToString(row2["MAP_URL"]) + "/" + Convert.ToString(row2["ENGINE_DEFAULT_URL"]);
 
if (text2.ToUpper().Equals(Convert.ToString(row2["MAPNAME"]).ToUpper()))
 
{
 
this.strMapDetail = text4;
 
}
 
this.ddlMap.Items.Add(new ListItem(row2["MAPNAME"].ToString(), text4));
 
}
 
}
 
}
 
else
 
{
 
this.ddlMap.Visible = true;
 
this.lblCountry.Visible = false;

{
 
this.strMapDetail = text5;
 
}
 
this.ddlMap.Items.Add(new ListItem(row3["MAPNAME"].ToString(), text5));
 
}
 
}
 
}
 
else
 
{
 
 
StringBuilder builder1 = new StringBuilder();
 
builder1.Append("SELECT MAPNAME FROM MAP_SUPERUSER ");
 
builder1.Append(" WHERE ");
 
builder1.Append(" SUPERUSERID = (SELECT SUPERUSERID ");
 
builder1.Append(" FROM USERS WHERE USERID='" + strUserId + "')");
 
builder1.Append(" AND DEFAULT_MAP ='1'");
 
string text6 = (string)cls1.ExecuteScalar(builder1.ToString());
 
this.lblCountry.Text = text6;
 
this.strCountry = text6;
 
}
 
this.ViewState["COUNTRY"] = this.strCountry;
 
}
 
}

Now to my problem, when I choose any values from the dropdownlist1, the values in the html select control called ddlmap gets vanished.

eg. if there are three values 1,2,3 by default the value 1 is displayed on the select control and the values 2,3 are in the dropdown area whereas when i choose the value from dropdownlist(se rver control) nothing is displayed. The select control is empty and all the values 1,2,3 are in dropdown area.



i tried giving ddlmap.Selected Index = 1;

but to no avail.





Kindly help please
