I am using a confirm function is js and calling the function on the click of a button, i am getting the Confirm box on the click of the button in the button, but the message that i am passing in the Confirm function is not appearing.Here is the code below

<script type="text/javascript">

C#

function confirm() {
            var x;
        var r=confirm('Are You Sure!');
        if (r==true)
        {
            x="You pressed OK!";
        }
        else
        {
            x="You pressed Cancel!";
        }

I am passing a message here Are you sure but i m not getting it, rather it is blank and what i am getting is only the two buttons that is OK & Cancel.

XML

<asp:GridView ID="gdvData"  runat="server" Height="159px" Width="511px"
                   AutoGenerateColumns="False">

                   <Columns>

<asp:TemplateField HeaderText="Delete" HeaderStyle-BackColor="#4EA600" HeaderStyle-ForeColor="White">
<itemtemplate>
<asp:LinkButton ID ="ButtonDelete" Text="Delete" OnClientClick="confirm()" value="Are You Sure!" runat="server" />

And also please let me know how can i use the onclick event of the Buttons i.e. Ok and Cancel of the Confirm function

hi,

try to change like below:

<asp:linkbutton id="ButtonDelete" text="Delete" onclientclick="return confirmmessage();" value="Are You Sure!" runat="server" />

JavaScript

<script>
  function confirmmessage()
  {
     if(confirm('Are you sure!'))
     { //yes  
       // to call your sp on coding side
        $.ajax({
                type: "POST",
                url: "Demo.aspx/DeleteSupplierDetails",
                contentType: "application/json; charset=utf-8",
                data: "{R1:'" + value+ "', R2:'" + Value+ "', R3:'" + Value+ "', R4:'" + Value + "'}",
                dataType: "json",
                success: function (data) {
                    if(data.d == true)
                        alert('successfully call sp');

                },
                failure: function (data) {
                    alert('sp not called');
                }
            });
     }
     else
     { //No  
        return false;
     }
  }
</script>

// on server side

XML

[System.Web.Services.WebMethod(true)]
        public static bool DeleteSupplierDetails(string R1,string R2,string R3,string R4)
        { 
             //call your sp
             // if success
             return true;
         }

hope it helps.

Thanks the above solution worked fine but one issue i have here is on the aert box heading it is showing like "Windows Internet Explorer" Can i get this changed and how to use the onclick event of the OK and Cancel button of the message

Harshil_Raval 5-Aug-13 6:58am

I am not sure how to change heading of confirm message. But for button event see my answer, i have comment //yes, means when ok button clicked flow comes in that section, and if cancel button clicked then see //No, flow will come in that section. For changing header of confirm, think you can not change it. If you really need to change it, then create your own popup. There are many js available for it.

Rock_Dead 5-Aug-13 7:17am

I want to call a stored procedure on the click of OK button how can that be done

Harshil_Raval 5-Aug-13 7:23am

To achieve it use jquery ajax method. You can find out many tutorials and post about this.Check my updated code.

Rock_Dead 5-Aug-13 7:25am

Can i have an example on this please? and where can i find your updated code?

Harshil_Raval 5-Aug-13 7:29am

now check.

Rock_Dead 5-Aug-13 7:35am

The following part can be done under the Data Access layer right?

[System.Web.Services.WebMethod(true)]
public static bool CallSp()
{
//call your sp
// if success
return true;
}

Harshil_Raval 5-Aug-13 7:42am

In code behind of your page. Other way is to create webservice, and call this function from web service.

Rock_Dead 5-Aug-13 7:49am

Cant we do it the way i have done above?? like writing a method in DataAcess layer and calling the SP in the method.

Rock_Dead 5-Aug-13 7:39am

I have written the follwing method for calling the SP in dataaccess layer, is that fine?

public Boolean DeleteSupplierDetails(String R1, String R2, String R3, String R4)
{

Database db = Helper.CreateDatabase();

DbCommand cmd = db.GetStoredProcCommand("PDSS_STAGING_DEV.Delete_SupplierDetails");
cmd.CommandType = CommandType.StoredProcedure;

db.AddInParameter(cmd, "P_SOURCE_ENTITY", DbType.String, R1);
db.AddInParameter(cmd, "P_PLANT_CODE", DbType.String, R2);
db.AddInParameter(cmd, "P_SUPPLIER_NUMBER", DbType.String, R3);
db.AddInParameter(cmd, "P_SUPPLIER_GROUP_NUMBER", DbType.String, R4);
db.AddOutParameter(cmd,"P_RETURN_MSG", DbType.String,10);
db.ExecuteNonQuery(cmd);
return db.

Harshil_Raval 5-Aug-13 7:49am

public Boolean DeleteSupplierDetails(String R1, String R2, String R3, String R4) it should be public static Boolean DeleteSupplierDetails(String R1, String R2, String R3, String R4). And from design side, in $.ajax, hope you have passed your parameter. They can be specify in data:{R1:'" + value+ "', R2:'" + Value+ "', R3:'" + Value+ "', R4:'" + Value+ "'}",

Rock_Dead 5-Aug-13 7:51am

From the design point of view, what needs be done i am not sure about this?

Harshil_Raval 5-Aug-13 7:56am

Check again updated code.

Rock_Dead 5-Aug-13 7:59am

If you dont mind can i have your personal mail Id.. for more discussions on this, it would be of great help if you can share it with me

Harshil_Raval 5-Aug-13 8:07am

Hi, friend no one will post their email id here. don;t worry ask question i will give you answer, if i can. For more detail of this kind of method search on google, there are lot's of articles which can help you more than me. :-)

Rock_Dead 5-Aug-13 8:10am

ok, so in my HTML code like this now

<script>
function confirmmessage()
{
if(confirm('Are you sure!'))
{ //yes
// to call your sp on coding side
$.ajax({
type: "POST",
url: "Demo.aspx/DeleteSupplierDetails",
contentType: "application/json; charset=utf-8",
data: "{R1:'" + value+ "', R2:'" + Value+ "', R3:'"

+ Value+ "', R4:'" + Value + "'}",
dataType: "json",
success: function (data) {
if(data.d == true)
alert('successfully call sp');

},
failure: function (data) {
alert('sp not called');
}
});
}
else
{ //No
return false;
}
}
</script>

and the dataaccess method that will be calling the SP will look like this, is that fine

public Boolean DeleteSupplierDetails(String R1, String R2, String R3, String R4)
{

Database db = Helper.CreateDatabase();

DbCommand cmd = db.GetStoredProcCommand("PDSS_STAGING_DEV.Delete_SupplierDetails");
cmd.CommandType = CommandType.StoredProcedure;

db.AddInParameter(cmd, "P_SOURCE_ENTITY", DbType.String, R1);
db.AddInParameter(cmd, "P_PLANT_CODE", DbType.String, R2);
db.AddInParameter(cmd, "P_SUPPLIER_NUMBER", DbType.String, R3);
db.AddInParameter(cmd, "P_SUPPLIER_GROUP_NUMBER", DbType.String, R4);
db.AddOutParameter(cmd,"P_RETURN_MSG", DbType.String,10);
db.ExecuteNonQuery(cmd);
return db.

Harshil_Raval 5-Aug-13 8:20am

add static keyword in your DeleteSupplierDetails it should be like public static Boolean DeleteSupp... And don't forget to add [System.Web.Services.WebMethod(true)] exactly top of this function. And in your aspx page , change url, demo.aspx to your page name in which you are working. ok.

Rock_Dead 5-Aug-13 8:51am

so u mean to say above the Method public static Boolean DeleteSupplierDetails(String R1, String R2, String R3, String R4) u want me to make [System.Web.Services.WebMethod(true)] and secondly in the .aspx case i didnt get ur point

Harshil_Raval 5-Aug-13 8:55am

Right. For aspx page in function confirmmessage() in $.ajax({ change url: "Demo.aspx/DeleteSupplierDetails", here replace Demo.aspx with your page name. ok now.

Rock_Dead 13-Aug-13 3:25am

Harshil, I am trying to delete a selected row in the gridview, the User has a option of selecting the row to be deleted and he can delete only one row at a time. How can this be done.

Under the .CS page i have written the following code.

protected void gdvData_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
InBoundDataBO obj = new InBoundDataBO();
int SUPPLIER_NUMBER = Convert.ToInt32(gdvData.Rows[e.RowIndex].Cells[4].Text);
string SOURCE_ENTITY = gdvData.Rows[e.RowIndex].Cells[2].Text.ToString();
string PLANT_CODE = gdvData.Rows[e.RowIndex].Cells[3].Text.ToString();
string SUPPLIER_GROUP_NUMBER = gdvData.Rows[e.RowIndex].Cells[5].Text.ToString();

obj.DeleteSupplierDetails(SUPPLIER_NUMBER, SOURCE_ENTITY, PLANT_CODE, SUPPLIER_GROUP_NUMBER);
}

Under the Data Acess Layer i have written the following method.

public static void DeleteSupplierDetails(String R1, String R2, String R3, String R4,out String message)
{
message = String.Empty;
Database db = Helper.CreateDatabase();

DbCommand cmd = db.GetStoredProcCommand("PDSS_STAGING_DEV.Delete_SupplierDetails");
cmd.CommandType = CommandType.StoredProcedure;

db.AddInParameter(cmd, "P_SOURCE_ENTITY", DbType.String, R1);
db.AddInParameter(cmd, "P_PLANT_CODE", DbType.String, R2);
db.AddInParameter(cmd, "P_SUPPLIER_NUMBER", DbType.String, R3);
db.AddInParameter(cmd, "P_SUPPLIER_GROUP_NUMBER", DbType.String, R4);
db.AddOutParameter(cmd,"P_RETURN_MSG", DbType.String,10);
db.ExecuteNonQuery(cmd);
message = cmd.Parameters["P_RETURN_MSG"].Value.ToString().Trim();
}
