Getting the nested gridview values when it is inside the content placeholder in javascript

function  Rdbtn(index)

finding the values inside the nested gridview Using Javascript / (using rowindex to find the nested gridview)/ (finding the selected rowindex of gridview on mouse click on the gridview row)

In Design Page

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

//get the row index and client id ,cell value
function showClickPage(rowid,id,selectedid)
{
 
var billamt=0;
var admissibleamt=0;
var nonadmissibleamt=0;
var billamt_tot=0;
var admissibleamt_tot=0;
var nonadmissibleamt_tot=0;
 var gridView1 = document.getElementById('<%=GVBillDetails.ClientID %>');
 var idExt=rowid ;
     if(parseInt(idExt,10) <= 9)
     {
         idExt = "0" + idExt ;               
     }           
     var VExtGrid = "GVBillDetails_ctl"+idExt;       
     var gridView = document.getElementById(VExtGrid+"_GVBillDetails1");
     for (var i = 1; i < gridView.rows.length - 1; i++)
     {
        var inputs1 = gridView.rows[i].getElementsByTagName('input')[0];
          if (inputs1.value.length<1)
          {
           nonadmissibleamt=0;
          }
         else
          {
           nonadmissibleamt =parseFloat(inputs1.value);
          }
       nonadmissibleamt_tot = nonadmissibleamt_tot +   nonadmissibleamt;
     }
      gridView.rows[gridView.rows.length - 1].getElementsByTagName('input')[0].value = nonadmissibleamt_tot;
      for (var i = 1; i < gridView.rows.length - 1; i++)
     {
        var inputs2 = gridView.rows[i].getElementsByTagName('input')[1];
          
          if (inputs1.value.length<1)
          {
           admissibleamt=0;
          }
         else
          {
           admissibleamt =parseFloat(inputs2.value);
          }
       admissibleamt_tot = admissibleamt_tot +   admissibleamt;
     }
      gridView.rows[gridView.rows.length - 1].getElementsByTagName('input')[1].value = admissibleamt_tot;  
}
</script>


in code behind:


 protected void GvBilldeatails_OnRowCreated(object sender, GridViewRowEventArgs e)
    {
       /// Gridview index will starts with  -1 so we are adding 2 to the current index here
       /// call the javscript function with 3 parameters as we are passing here


        int index = e.Row.RowIndex + 2;

        e.Row.Attributes.Add("onclick", "showClickPage('" + index + "','" + e.Row.ClientID + "','" + e.Row.Cells[0].Text + "');");

    }

-------------------------


or another method


You can attach an mouse over event handler to the rows of the grid in the OnRowDataBound event handler:

C#:
protected void OnGridRowDataBound(object sender, GridRowEventArgs args)
{
        args.Row.Attributes["onmouseover"] = "handleMouseOver(" + args.Row.RowIndex.ToString() + ")";
        ...
}

JavaScript:
<script type="text/javascript">
        function handleMouseOver(rowIndex) {
                alert('mouse over: ' + rowIndex);
        }

///after finding rowindex here same as above javscript we need to fallow

</script>

Instead of default button click on page load, we can call any other particular button click

Instead of default button click on page load, we can call any other particular button click

In design page:

<script language="javascript" type="text/javascript"> 
 
        function clickButton(e, buttonid){  
 
          var evt = e ? e : window.event; 
 
          var bt = document.getElementById(

buttonid); 
 
          if (bt){  
 
              if (evt.keyCode == 13){  
 
                    bt.click();  
 
                    return false;  
 
              }  
 
          }  
 
        } 
 
    </script>


in Code behind:
    

    if (!IsPostBack)
         {
           
                 Textsearch.Attributes.Add("onkeypress", "return clickButton(event,'" + Btnsearch.ClientID + "')"); 
          
         }


Here after any keypress in the text seach box it will take to the search button click instead of default button

 

--------------------------------------------------------------------------

or

 

In form tag only we can set the Default focus and default button for a form as below

 

   <form id="form1" runat="server" defaultfocus="Textsearch" defaultbutton="Btnsearch">

 

 It will take given controls on page load...

 

 

 

Converting string to date format in C#

                                LBLDate.Text = authorizationInfo["authorizedtime1"].ToString();

                                string date1 = LBLDate.Text.ToString();

                                DateTime date = DateTime.Parse(date1);

                                string newdate = string.Format("{0:dddd ,MMM dd ,yyyy}", date);

                                LBLDate.Text = newdate.ToString();
