Question

I have binded a custom datatable to gridview. Now I want to validate if the value of cells of the column “DocumentsAttached” is Yes or No. If it is yes, then an alert message displaying ” Documents are Attached”. If No, a pop up box with message would you like to continue” Yes/No…If yes, is chosen my submit button should go through otherwise no.

Hope i made sense until now. Below is my aspx

 <asp:GridView ID="UploadDocs" AutoGenerateColumns="False" runat="server" 
         EnableViewState="true" onrowdatabound="dgdUpload_RowDataBound" style="margin-top: 0px">

 <Columns>

<asp:HyperLinkField  DataTextField="DocName" HeaderText="Invoice File Name" DataNavigateUrlFields="FilePath" DataNavigateUrlFormatString="{0}">   
</asp:HyperLinkField>
  <asp:BoundField HeaderText="Document Included" DataField="DocumentsAttached" ReadOnly="true" />
 <asp:BoundField HeaderText="Identifier" DataField="Identifier" Visible="false"/>
 <asp:CommandField ButtonType="Button" HeaderText="Delete" ShowDeleteButton="true"/>
</Columns>
 </asp:GridView>
   <asp:Button ID="btnSubmit" runat="server" Text="Save to MassUploadList" />

Can anyone help me to achieve this please.

The function that I used to serve my purpose is below

<script language="javascript" type="text/javascript">

function Validate() {
    var cntrlname = document.getElementById('<%= gridview1.ClientID %>');
    var gridcell;
    var retVal = 1;
    var result = 1;
    for (i = 1; i < cntrlname.rows.length; i++) {
        if (cntrlname.rows[i].cells[2].innerText == "No") {
            retVal = 0;
        }
        if (retVal == 0) {
            return window.confirm("One of the Attachments is missing, would you like to proceed")
        }
         else{
             return true;
         }
         }
}


function window.confirm(str) {
    execScript('n = msgbox("' + str + '","4132")', "vbscript");
    return (n == 6);
}

The column documents attached is readonly, the user will not be able to make any changes to it.So , this displays a confirmation box if there any attachments missing, if the user is ok …it will execute the server side code otherwise will not.
