I created a gridview using Telerik asp.net/ajax controls and when I run the app locally the grid works fine but when pushed to my server I get the same error for all of my methods:
ASP.default_aspx' does not contain a definition for 'IssuesGrid_OnItemUpdated' and no extension method 'IssuesGrid_OnItemUpdated' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?)
I have tried deleting the reference in the grid and creating it again and letting VS create the method and then it'll work until I do that for all of the methods throwing the error and then it starts all over again.
Here is the aspx page:
<telerik:RadGrid ID="Issues" runat="server" CellSpacing="0" DataSourceID="GridSource" GridLines="None" Skin="Metro"
AllowPaging="True" AllowSorting="True" AllowFilteringByColumn="True" OnItemDataBound="Issues_OnItemDataBound"
PageSize="30" EnableLinqExpressions="false" EnableHeaderContextMenu="true" EnableHeaderContextFilterMenu="true"
AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True"
OnItemUpdated="Issues_OnItemUpdated" OnItemInserted="Issues_OnItemInserted" OnItemDeleted="Issues_OnItemDeleted"
OnItemCommand="Issues_OnItemCommand"
AutoGenerateColumns="False" ShowStatusBar="True" HorizontalAlign="Center" Height="900px">
And here are my methods in my cs file:
protected void Issues_OnItemUpdated(object sender, GridUpdatedEventArgs e)
{
if (e.Exception != null)
{
e.KeepInEditMode = true;
e.ExceptionHandled = true;
DisplayMessage(true, "Defect " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"] + " cannot be updated. Reason: " + e.Exception.Message);
}
else
{
DisplayMessage(false, "Defect " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"] + " updated");
}
}
protected void Issues_OnItemInserted(object source, GridInsertedEventArgs e)
{
if (e.Exception != null)
{
e.ExceptionHandled = true;
e.KeepInInsertMode = true;
DisplayMessage(true, "Defect cannot be inserted. Reason: " + e.Exception.Message);
}
else
{
DisplayMessage(false, "Defect inserted!");
}
}
protected void Issues_OnItemDeleted(object source, GridDeletedEventArgs e)
{
if (e.Exception != null)
{
e.ExceptionHandled = true;
DisplayMessage(true, "Defect " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"] + " cannot be deleted. Reason: " + e.Exception.Message);
}
else
{
DisplayMessage(false, "Defect " + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"] + " deleted");
}
}
protected void Issues_OnItemCommand(object source, GridCommandEventArgs e)
{
if (e.CommandName == RadGrid.InitInsertCommandName) //"Add new" button clicked
{
var editColumn = (GridEditCommandColumn)Issues.MasterTableView.GetColumn("EditCommandColumn");
editColumn.Visible = false;
}
else if (e.CommandName == RadGrid.RebindGridCommandName && e.Item.OwnerTableView.IsItemInserted)
{
e.Canceled = true;
}
else
{
var editColumn = (GridEditCommandColumn)Issues.MasterTableView.GetColumn("EditCommandColumn");
if (!editColumn.Visible)
editColumn.Visible = true;
}
}
What's weird is I have an ondatabound method that is just fine and worked before any of these problems started and continues to work. I tried changing the 'object sender' to 'object source' but still a no go.
Here is the OnDataBound event:
protected void Issues_OnItemDataBound(object source, GridItemEventArgs e)
{
var gridDataItem = e.Item as GridDataItem;
if (gridDataItem != null)
{
var item = gridDataItem;
//Tooltips
if (!item.IsInEditMode)
{
var cell = item["Description"];
if (cell.Text.Length > 40)
{
var originaltext = cell.Text;
cell.Text = cell.Text.Remove(40) + "...";
cell.ToolTip = originaltext;
}
}
}
}
Any help on what I am doing wrong would be great!
