alert return false on confirm true and return true on confirm false on a value exists in asp.net

Hi,

Please refer below code.

HTML

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    function checkActiveAffiliates() {
        var IsValid = false;
        var inActiveAffiliates = $('[id*=hfActiveAffiliates]').val();
        if (parseInt(inActiveAffiliates) > 0) {
            if (confirm('Do you want to approve application which contains in active affiliate?')) {
                IsValid = true;
            }
        }
        return IsValid;
    }
</script>
<asp:TextBox ID="txtRequestedAffiliate" runat="server" OnTextChanged="txtRequestedAffiliate_TextChange"
    AutoPostBack="true" />
<asp:ImageButton ID="ibtApprove" align="absmiddle" runat="server" ImageUrl="~/Images/btn_Approve.gif"
    ToolTip="Approve" OnClick="ibtApprove_Click" OnClientClick="return checkActiveAffiliates()">
</asp:ImageButton>
<asp:HiddenField ID="hfActiveAffiliates" runat="server" />

C#

protected void ibtApprove_Click(object sender, EventArgs e)
{
    int intSuccess = new BLRating().ApproveApplication(intAppNo, Session["UserId"].ToString());
    if (intSuccess > 0)
    {
        Hashtable htLog = new Hashtable();
        htLog["AppNo"] = intAppNo.ToString();
        htLog["ActivityLogId"] = "28";
        htLog["Description"] = "Application BMO -" + intAppNo + " Approved";
        htLog["UserId"] = Session["UserId"].ToString();
        htLog["Status"] = hdnStatus.Value.ToString();
        new BLLogDetails().InsertLogDetails(htLog);
        Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "Reload()", true);
    }
}
protected void txtRequestedAffiliate_TextChange(object sender, EventArgs e)
{
    string otherAffiliateName = txtRequestedAffiliate.Text;
    int inActiveAffiliates = new BLRating().InActiveAAffiliateChecking(otherAffiliateName);
    hfActiveAffiliates.Value = inActiveAffiliates.ToString();
}

I hope this will help you out.

the code doesnot enter to 'txtRequestedAffiliate_TextChange' function

It is textChange event of textbox also you need to set AutoPostback to true.

I have set as AutoPostBack true;

  <asp:TextBox ID="txtRequestedAffiliate" runat="server" CssClass="inpTxt" Width="90%" ReadOnly="true"                                            OnTextChanged="txtRequestedAffiliate_TextChange"  OnClientClick="return checkActiveAffiliates()" AutoPostBack="true" /></asp:TextBox>

josmi says:

OnClientClick="return checkActiveAffiliates()"

 Remove this from textbox and add it to your ImageButton

Here it is javascript method

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    function checkActiveAffiliates() {
        var IsValid = false;
        var inActiveAffiliates = $('[id*=hfActiveAffiliates]').val();
        if (parseInt(inActiveAffiliates) > 0) {
            if (confirm('Do you want to approve application which contains in active affiliate?')) {
                IsValid = true;
            }
        }
        return IsValid;
    }
</script>
