Telerik check blank row exist

[Larry]

I am currently create an web application to load the selected order in the client transaction record by clicking the copy button in the RadGrid. I implement this by getting the id of the order and retrieve the required entity to insert the form.

JS Runtime Error That Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object By using MVVM Model , I preset the blank row to be null in terms of the mapped fields such as consumer ID , order ID , consumer Name , Price and so on .

The Order Reference Id is named as referenceOrder and retrieve the LoadReference to insert the record

I am currently using C# , Visual Studio 2012.

What I want to ask is there any methodology to check if the row is blank before the copy action being executed ?

The below is my code

 protected void grdCustomerReport_ItemCommand(object sender, GridCommandEventArgs e)
    {
        // [Start] Declare Grid and GridData.
        RadGrid CurrentGrid = (RadGrid)sender;
        GridDataCustomerReport GridSource = PageSource.GrdCustomerReport;
        //[End] 
        if (e.CommandName == "CustomInsert" &&
            GridSource.state != GridModelState.Edit)
        {
           //Add blank row
        }
        else if (e.CommandName == "DeleteCurrent")
        {
          //Delete Row
            CurrentGrid.Rebind();
        }
        else if (e.CommandName == "Copy") <--I click the button and retrieve the dataset index 
        {
            //Check if there is empty row  ? 

            int referenceOrder ;
            int rowIndex = Convert.ToInt32(e.CommandArgument);

            RadComboBox cbo= (RadComboBox) CurrentGrid.Items[rowIndex].FindControl("cboCode");
            if (cbo.SelectedIndex > 0  && cbo.SelectedValue != "")
            {
                referenceOrder = Convert.ToInt32(cbo.SelectedValue);
                PageSource.SetOrder(referenceOrder );
                LoadReference();
            }
            else
            {
               winAlert.RadAlert("<b>" + "Please Select Reference Orderin the Dropdown List" + "</b>.<br />", 330, 100, "", null);
            }
        }
    }

Hi Raju,

I am experiencing difficulties understanding your scenario. Could you please elaborate on who is firing the copy command. Isn't this being fired from a button in a grid row? If that is the case the grid item can not be blank and probably the CommandArgument is not passed correctly. I suggest that you modify the code like shown below:

else if (e.CommandName == "Copy") <--I click the button and retrieve the dataset index
        {
            //Check if there is empty row  ?

            int referenceOrder ;
            GridDataItem item = e.Item as GridDataItem;

            RadComboBox cbo= (RadComboBox) item.FindControl("cboCode");
            if (cbo.SelectedIndex > 0  && cbo.SelectedValue != "")
            {
                referenceOrder = Convert.ToInt32(cbo.SelectedValue);
                PageSource.SetOrder(referenceOrder );
                LoadReference();
            }
            else
            {
               winAlert.RadAlert("<b>" + "Please Select Reference Orderin the Dropdown List" + "</b>.<br />", 330, 100, "", null);
            }
        }

Could you please show us your markup with the relevant code-behind so we could get a better view over your setup? Also please elaborate more about the JavaScript error as I do not see a relation between the server-side code and JavaScript error.
