I have asp.net drop down list but I want to load previous classic asp page value into index of the drop down list using Java script.

I can able to take the previous page value with use of Java script.but I am unable set into asp drop down index when page is loaded. Drop down list showing only data from data base not from Java script value.

Protected void page_load()
{
    this.BindCountrydropdown();
}
Protected void BindCountrydropdown()
{
     /*I have written stored procedure to load values using Data adapter and data table*/
     this.ddlCountry.DataTextField=“Countryname”;
     this.ddlCountry.DataValueField=“CoubtryID”;
     this.ddlCountry.Databind();
}

In .aspx page. Java script:

<script>
    function loadpreviouspagevalues()
    {
        document.getElementById(“ddlCountry”).value=window.opener.parent.document.getElementById(“CountryName”).value;
    }
</script>
<body onload =“ loadpreviouspagevalues()”>
    <asp:DropDownList ID=“ddlCountry” runat =“server”> </asp:DropDownList>
   ...

Country name should loaded into ddlCountry index values.

First of all, there are multiple errors just in your javascript function.

function loadpreviouspagevalues(){
    document // should not be a capital "D"
    .getElementById //  No Extra "." should go after this
    ("ddlCountry").value = window.opener.parent.document.getElementById("CountryName").value; 
    // I am also skeptical about the inverted commas that you have used here. These are not surely correct
}

Change these and test. Also, when dealing with JavaScript, it is crucial to check browser console to see if any error is there and resolve it accordingly.

I see, you are fetching the value from another page, I would suggest you first validate if the value is properly being returned or not. If it is, then there is the syntactical issue that you need to fix in JavaScript.
