[Solved] Paging not working for dynamic radgrid

I have couple of issues related to dynamically created Radgrid.
Background: I have created a dynamic Radgrid which contains Templatecolumn in it, this template columns hold three dropdown list controls which work in a cascading manner. I'm pre-selecting the drop down and for new records its getting default selections. Everything works fine until I get into paging.

Issues: 1. Whenever I use paging the page number is selected in the grid but it always shows first page records.
2. The selections made in previous page dropdown list are not persisting during the paging.

I'm not sure if both are related to same thing. Here is my code for your reference. Your help is highly appreciated.

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

AddGrid();

}

private void AddGrid()

{

_grid = new RadGrid

{

ID = "TestGrid",

PageSize = 30,

ShowGroupPanel = false,

AllowSorting = false,

AllowPaging = true,

AutoGenerateColumns = false,

GridLines = GridLines.Vertical,

VirtualItemCount =0

};

_grid.ClientSettings.AllowDragToGroup = false;

_grid.ClientSettings.AllowColumnsReorder = false;

_grid.ClientSettings.AllowColumnHide = true;

_grid.ClientSettings.Animation.AllowColumnReorderAnimation = false;

_grid.ClientSettings.Animation.AllowColumnRevertAnimation = false;

_grid.MasterTableView.DataKeyNames = new[] { "Id" };

_grid.MasterTableView.ShowHeadersWhenNoRecords = true;

_grid.MasterTableView.UseAllDataFields = true;

_grid.MasterTableView.Name = "Master";

_grid.ItemDataBound += GridItemDataBound;

_grid.PageIndexChanged += new GridPageChangedEventHandler_grid_PageIndexChanged);

_grid.NeedDataSource += new GridNeedDataSourceEventHandler(_grid_NeedDataSource);

var countryTemplate= new GridTemplateColumn

{

UniqueName = "ADDCountry",

HeaderText = "Country Field",

Resizable = true,

};

countryTemplate.HeaderStyle.Font.Bold = true;

countryTemplate.ItemTemplate = new Templateclass(countryTemplate.UniqueName, ExcelColumns);

_grid.MasterTableView.Columns.Add(sourceTemplate);

var stateTemplate = new GridTemplateColumn

{

UniqueName = "ADDState",

HeaderText = "state Column Field",

};

stateTemplate .HeaderStyle.Font.Bold = true;

stateTemplate .ItemTemplate = new Templateclass(stateTemplate .UniqueName, null);

_grid.MasterTableView.Columns.Add(stateTemplate );

var CityTemplate = new GridTemplateColumn

{

UniqueName = "ADDCity",

HeaderText = "Mapping Rule",

};

CityTemplate .HeaderStyle.Font.Bold = true;

CityTemplate .ItemTemplate = new Templateclass(CityTemplate .HeaderText, null);

_grid.MasterTableView.Columns.Add(CityTemplate);

Content.Controls.Add(_grid);

}

void _grid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

((RadGrid)sender).MasterTableView.VirtualItemCount = bindingObject.Count;

((RadGrid)sender).CurrentPageIndex = ((RadGrid)sender).MasterTableView.CurrentPageIndex;

((RadGrid)sender).DataSource = bindingObject;

}

void _grid_PageIndexChanged(object sender, GridPageChangedEventArgs e)

{

((RadGrid)sender).MasterTableView.CurrentPageIndex = ((RadGrid)sender).CurrentPageIndex;

}

void GridItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem dataItem = (GridDataItem)e.Item;

DropDownList ddlCountry= (DropDownList)dataItem.FindControl("ddlCountry");

if (ddlCountry!= null)

{

ddlCountry.AutoPostBack = true;

ddlCountry.SelectedIndexChanged += new EventHandler(ddlCountry_SelectedIndexChanged);

}

public class Templateclass: ITemplate

{

public Templateclass(string colNames,List<string> CountryNames)

{

colName = colNames;

countryNames= CountryNames;

}

public void InstantiateIn(Control container)

{

//create a drop down controls for template columns

}

SendEmail causing issue with domains implementing DMARC

The popup send email dialog asks for a From Address. And if the sent from address is different, the email is composed with a "on behalf of". Unfortunately this is causing blocked emails, in particular when the From Address is from AOL and Yahoo.

AOL and Yahoo have implemented dmarc which prevents sending on behalf of emails.
http://www.dmarc.org/

So ideally, the From address collected on the input page would be the reply to address (not on behalf of). Is there some way to resolve this/override it? or is an improvement in the works?

Thanks,
Todd.

Telerik RadGrid - Issue with Reorder columns and postback

Hi,

We have an issue with the Telerik RadGrid which we believe is linked to this post:
http://www.telerik.com/community/forums/aspnet-ajax/grid/horizontalalign-on-client-columns-reorder.aspx

We have a custom Command Item Template which contains buttons that are shown or hidden within the grid pre render event.

When reordering the columns and then clicking anything that forces an autopost back, the buttons within the command item template are all shown.

I have included a checkbox below our grid:

<asp:CheckBox runat="server" ID="chk_box" AutoPostBack="True"/>

Clicking this after reordering the columns causes the show/hide in our pre render not to have an effect on the visibility of the buttons.

The above post mentions "This is because, with client column reorder, RadGrid rebinds implicitly on the next postback." Is this a bug with the RadGrid and if so has it been fixed?

Please note that setting RadGrid.MasterTableView.ClientSettings.ReorderColumnsOnClient = "false" does not fix the issue for us.

This is an urgent issue for us and any help would be very much appreciated,

Thanks,
Ryan

Custom Aggregate on a templated column with grouping

I have a grid which uses grouping. I would like to implement some functionality that calculates some group-level stats on some of the columns in the grid, however I need to use TemplateColumns, so the built-in aggregates won't work. I am able to do the calculation in the grid's ItemDataBound event, however, at this point in the grid cycle, I don't have access to know which group i am in so the calculations won't be made on a group-level, as I want. Does anyone know how to accomplish this? A simple example would be a grid with a Template column which shows an Integer (the template column is needed for a variety of treasons which aren't pertinent). I would like the group header (or footer) to show a calculation made on this column (such as the number of items in the group which are greater than some fixed value)

Grid Property is null

I am using the latest released version of the control. In Page_Load I have the following code:

RadFileExplorer1.TreeView.EnableDragAndDrop = true;
RadFileExplorer1.Grid.ClientSettings.AllowRowsDragDrop = true;

It fails on the second line because the .Grid property is null at that point? If I don't have that code the program seems to run fine.

For reference, I added the above code to the bottom of Page_Load in the program "PhysicalPathFileSystemProvider_Cs.zip"

located at the bottom of the page on http://www.telerik.com/support/kb/details/use-radfileexplorer-with-physical-and-shared-folder-s-paths

Bug: Accessing RadPanelItem's ClientID server side

Hello, I have a RadPanelBar that contains a RadPanelItem, similar to the configuration below. Both are assigned IDs with runat=server.

In my code-behind, I am trying to pass the RadPanelItem's clientID to the RadToolTipManager so that the Item will have a nice pretty tooltip on mouse over.

However, passing the RadPanelItem's clientID to the RadToolTipManager does not enable the tooltip -- I found out that the actual RadPanelItem's ClientID is not being assigned correctly -- it appears that the RadPanelItem's ClientID is the same as the RadPanelBar.

I think this may be a bug, since I am able to pass literally every other control's clientID to the RadTooltipManager successfully, and have the tooltip displayed correctly.

Please advise as to how I can pass the correct RadPanelItem.ClientID to the RadTooltipManager.

ascx code:

<telerik:RadPanelBar width="100%" ID="rdpPanelBar" runat="server" ExpandMode="MultipleExpandedItems">

<Items>

<telerik:RadPanelItem Text="Package" runat="server" Width=100% Value="PackageName" id="rdiPackage">

<ContentTemplate>

...

</ContentTemplate>

</Items>

</telerik:RadPanelItem>

</telerik:RadPanelBar>

code behind (vb net)

Dim item As RadPanelItem = rdpPanelBar.FindItemByValue("Package")

Dim test = rdpPanelBarClientID & "|" & rdiPackage.ClientID

RadToolTipManager1.TargetControls.Add(rdiPackage.ClientID, True)

RadToolTipManager1.Text = test

Is Rad Window using showModalDialog

Hi,

showModalDialog has been removed from Chrome few days ago, possibly from Opera too.

Firefox also warns that showModalDialog has been deprecated and planed to be removed.

Is Rad Window using that method and will be affected?

or it just might be a possible solution...?

Thanks,
Shay

RadGrid Select Row

So I've seen this thread answered over and over and according to what I've read, this should work no problem. But it's not. I just want to be able to select a record. I also want to enable the rowHoverStyle.

Nothing works. Not sure if it's a setting in my web.config or what. The link below shows that it isn't working and my code is below. The label is supposed to show the row data of the clicked row.

[Solved] RadEditor's HTML mode doesn't editable in Chrome version 37.0.2062.103 m

Hi Support,

The RadEditor's HTML mode doesn't editable in Chrome version 37.0.2062.103 m.

The bug occurs when adding a flash player via Flash Manager into the content and switching into HTML edit mode.

Same issue reproduces in the example page: http://demos.telerik.com/aspnet-ajax/editor/examples/filemanagers/defaultcs.aspx

What could be the issue?

Thanks,
