Sorting Of The Gridview column without using Datasource

 protected void GVinsurance_onSorting(object sender, GridViewSortEventArgs e)
        {

            DataTable dt1 = (DataTable)ViewState["DT"];//GVProvider.DataSource as DataTable;
            if (dt1 != null)
            {

                if (dt1 != null)
                {
                    DataView dvSortedView = new DataView(dt1);

                    dvSortedView.Sort = e.SortExpression + " " + getSortDirectionString(e.SortDirection);

                    GVInsurance.DataSource = dvSortedView;
                    GVInsurance.DataBind();
                }

            }
        }

 private string getSortDirectionString(SortDirection sortDirection)
        {
            string newSortDirection = String.Empty;

            if (Convert.ToString(ViewState["newSortDirection"]) == "DESC")
            {
                ViewState["newSortDirection"] = "ASC";
            }

Validating number of characters before and after decimal point using javascript

  function validatemaxAmt(sender, evt)
{
              var splitValue = sender.value.split(".", 2);

        
                  if(splitValue[0] != null)
                 {
                    if(splitValue[0].length < 7)
                    {
                       // alert("Correct format.");
                        return true; // allow postback (if applicable)
                    }
                    else
                    {
                        alert("Incorrect number of decimal digits.");
                        sender.value="0";
                        sender.focus();
                        return false; // disallow postback (if applicable)
              
                    }
                }
}

Handling the radio button list with yes or no confirmation message in C#

rdbbilltype.Attributes.Add("onclick", "if(!confirm('Are you sure to change the bill type? ')) return false;");

Looks simple but it will allow only when the OK button is clicked, Or else it wont change the selection.

Awesome...!!!

Javascript validation for special characters in ASP.NET/ C#

function validatespecailchars()
{

     var txtbox = document.getElementById('<%=txtsearch.ClientID %>').value;
   
      var str="<";
        var str1=">";
        var str2="--";
        var str3=";";
        var str4="'";

    if((txtbox.indexOf(str)>=0)||(txtbox.indexOf(str1)>=0)||(txtbox.indexOf(str2)>=0)||      (txtbox.indexOf(str3)>=0)||(txtbox.indexOf(str4)>=0))
    {
         alert('Special Characters are not Allowed.');
        // you can focus here that particular control
     }
}

Generating the Graphs in Asp.net

In desing page

// put one literal 

<asp:Literal ID="TATLiteral1" runat="server"></asp:Literal>

In Code Behind

        string sql = "", sql1 = "", sql2 = "", sql3="";

        string condition = "";

        string strXML, strCategories1 ;

        DataTable fdt = null;

        DataTable fdt1 = null;

        DataTable fdt3 = null;

        OracleCommand cmd = null;

        OracleDataAdapter da = null;

       /// genarate the data for your graph

            sql = " Your Query to get data";

            fdt1 = new DataTable();

            cmd = new OracleCommand(sql, conn);

            da = new OracleDataAdapter(cmd);

            da.Fill(fdt1);

     // after getting data put it in the XML format as below

  //  header tag for graph

   

         strXML1 = "<graph  rotateNames='0' animation='1'  numdivlines='4'  baseFont='Arial' baseFontSize='10' baseFontColor='000000' useRoundEdges='1' showLegend='0' bgColor='ffffff' borderColor='ffffff' showYAxisValues='0'>";

   // categories

  strCategories1 = "<categories> <category name='0-2 Hrs' /> <category name='>2 Hrs' /></categories>";

                strXML1 += strCategories1;

// dataset you are providing

                strXML1 += " <dataset seriesName='"+fdt3.Rows[0]["HOSPNAME"]+"' color='8B0000'   showValues='1'>";

                strXML1 += "<set   value='" + fdt1.Rows[0]["Total"].ToString() + "' />";

                strXML1 += "<set   value='" + fdt1.Rows[1]["Total"].ToString() + "' />";

                strXML1 += " </dataset>";

                strXML1 += " <dataset seriesName='"+fdt3.Rows[1]["HOSPNAME"]+"' color='2F4F4F' showValues='1'>";

                strXML1 += "<set   value='" + fdt1.Rows[2]["Total"].ToString() + "' />";

                strXML1 += "<set   value='" + fdt1.Rows[3]["Total"].ToString() + "' />";

                strXML1 += " </dataset>";

                strXML1 += " <dataset seriesName='" + fdt3.Rows[2]["HOSPNAME"] + "' color='20B2AA' showValues='1'>";

                strXML1 += "<set  value='" + fdt1.Rows[4]["Total"].ToString() + "' />";

                strXML1 += "<set  value='" + fdt1.Rows[5]["Total"].ToString() + "' />";

                strXML1 += " </dataset>";

               

                strXML1 += "</graph>";

// binding to literal 

                TATLiteral1.Text = FusionCharts.RenderChartHTML("../ChartsLicense/MSColumn2D.swf", "", strXML1, "Preauthinfo", "350", "170", false);

NOTE : Graph is also depends on the swf files which we provide  like BAR, COLUMN , LINE , STACKED (here m using Multi series column graph)  So download all the swf files from  fusioncharts.com ( refer it for more info for graphs)
