Index out of range in .NET 4.5

Jan 18, 2013 06:30 AM|LINK

Hi,

We have a project that use in .NET 2.0 and it works. However, when we upgrade it to .NET 4.5, it shows following error when we do the record deletion.

Microsoft jscript runtime error
Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range.
Must be non-negative and less than the size of the collection.

But, it works in .NET 2.0 and we can insert & modify record successfully.

Can anyone help us to solve this problem?

switch (e.CommandName)
        {
            case "Edit":
                {
...
                }
            case "Delete":
                {
                    int total = 0, done = 0;
                    foreach (GridViewRow gvr in gvwList.Rows)
                    {
                        if ((gvr.Cells[0].FindControl("cbRemoval") as CheckBox).Checked)
                        {
                            done += Dir.Delete(decimal.Parse((gvr.Cells[1].FindControl("imbViewDetail") as ImageButton).CommandArgument));
                            total++;
                        }
                    }
                    sb.Length = 0;
                    ltlMessage.Text = sb.AppendFormat("(Deleted record(s): {0} of {1} )", done, total).ToString();
                    break;
                }
        }

Here is our delete code. After my checking, no error is found in this delete method. However, after exit this gvwList_RowCommand(). it throws error .NET 4.5 and we still cannot find out the problem. What's more, our record is already deleted after our checking.

All these is work in .NET 2.0.

Can you debug your app by pressing F5 and then tell us at which statement the error is thrown out？

After checking, the error is thrown in here ScriptResource.axd:

function Sys$WebForms$PageRequestManager$_endPostBack(error, executor, data) {
        if (this._request === executor.get_webRequest()) {
            this._processingRequest = false;
            this._additionalInput = null;
            this._request = null;
        }
        var handler = this._get_eventHandlerList().getHandler("endRequest");
        var errorHandled = false;
        if (handler) {
            var eventArgs = new Sys.WebForms.EndRequestEventArgs(error, data ? data.dataItems : {}, executor);
            handler(this, eventArgs);
            errorHandled = eventArgs.get_errorHandled();
        }
        if (error && !errorHandled) {
            throw error;
        }
    }

An error is passed in this function:

Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index
