Hi,

I have a RadGrid that opens inside of a RadWindow. The user can re-order the rows by drag and drop, but if the grid is longer than the height of the RadWindow, it does not scroll. Is there a way to scroll the RadWindow as the user is moving the item down the list?

[Solved] Missing Columns collection in InfrastructureExporting when colums are added programmatically

We would like to set the width of columns in xlsx export from a RadGrid. I do this by using e.ExportStructure.Tables[0].Columns in the InfrastructureExporting event handler. If columns are declaratively set in the aspx file when this works fine.

If, however, the columns of the RadGrid are added by setting AutoGenerateColumns="true" or manually in Page_Load, then the Columns collection is empty. Why is this, and are there some other way to set the width of the columns in the xlsx file?

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" OnNeedDataSource="RadGrid1_NeedDataSource" OnInfrastructureExporting="RadGrid1_InfrastructureExporting">
<ExportSettings Excel-Format="Xlsx" />
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" />

.cs:

public class Person
{
   public string ID { get; set; }
   public string Name { get; set; }
   public DateTime? Date { get; set; }
}

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
   RadGrid1.DataSource = new List<Person> {
     new Person { ID = "1", Name = "Adam", Date = new DateTime(1973, 4, 12) },
     new Person { ID = "2", Name = "Bertil", Date = null },
     new Person { ID = "3", Name = "Ceasar", Date = new DateTime(1973, 10, 27) },
   };
}

protected void Button1_Click(object sender, EventArgs e)
{
RadGrid1.MasterTableView.ExportToExcel();
}

protected void RadGrid1_InfrastructureExporting(object sender, Telerik.Web.UI.GridInfrastructureExportingEventArgs e)
{
e.ExportStructure.ColumnWidthUnit = Telerik.Web.UI.ExportInfrastructure.ExportUnitType.FormatDefault;

// ERROR: The Columns collection is empty if the columns of radgrid are auto-generated or dynamically added in code behind
foreach (var col in e.ExportStructure.Tables[0].Columns)
{
col.Width = 20;
}
}

[Solved] Grid in batch mode on a master details form

Greetings,

RadGrid, while in the batch mode, keeps items locally until saveChanges (or any of the other save methods) is called. It then serializes the items to a string and posts it to the server.

What if I have other controls on the page that cause post backs?
For example, on a master details form, the user will enter data in the header then add/edit/delete some records to the grid, then clicks the save button of the form. The grid won't raise any events then and the grid data will be lost as it wasn't sent as part of the request.
Is my understanding right? Or there's a method to make batch mode grids participate in post backs like simple controls do?

I ask this because I may have more complex forms with multi level of details and each level will have its batch mode grid, and I can't make any of the grids initiate the post back using saveChanges.

Microsoft.Ajax axd files does not cache/ return 304

I have the following settings

1. web.config

        <system.web.extensions >
<scripting ><webServices/>

<scriptResourceHandler
       enableCompression="true"
       enableCaching="true" />
</scripting >

</system.web.extensions >

2. compilation debug = false in web.config and master page

3. <telerik:RadScriptManager ID="ScriptManager" runat="server" ScriptMode="Release" EnableScriptCombine="false" CacheSettings-Enabled="true" /> in master page.

However if i enable cdn, cdn is able to server 304, I assume it is because the files are static in the CDN.

Can Telerik support advise howw to make axd return 304?

Thanks.

How to fetch the listbox records in server side in c#

hi all,

my scenario:

i have three listbox, EmployeeName as Parent List Box, ProjectAdmin and ProjectReader as Child List box. i will drag and drop from parent list to its child list box. the drag and drop concept is working fine for me(i doing this in client side using Javascript). while i am inserting the details in database in c#, the Child list box shows empty. i cannot fetch the items in c# server, where the drag and drop done in javascript.

HTML Code

<table class="normal_grid">

<tr>

<th style="width: 17%">

<asp:Label ID="lblemployeename" runat="server" Text="Employee Name"></asp:Label>

</th>

<td class="field" style="width: 17%">

<telerik:RadListBox runat="server" ID="rlbemployeename" EnableDragAndDrop="true"

Width="150px" Height="150px" OnClientDropped="lbemployeenamedropped">

</telerik:RadListBox>

</td>

<th style="width: 16%">

<asp:Label ID="Label1" runat="server" Text="Project Admin"></asp:Label><span class="hlt_txt">*</span>

</th>

<td class="field" style="width: 17%">

<telerik:RadListBox runat="server" ID="rlbadminname" EnableDragAndDrop="true" Width="150px"

Height="150px" OnClientDropped="lbadminnamedropped">

</telerik:RadListBox>

</td>

<th style="width: 16%">

<asp:Label ID="Label2" runat="server" Text="Project Reader"></asp:Label><span class="hlt_txt">*</span>

</th>

<td class="field" style="width: 17%">

<telerik:RadListBox runat="server" ID="rlbreadername" EnableDragAndDrop="true" Width="150px"

Height="150px" OnClientDropped="lbreadernamedropped">

</telerik:RadListBox>

</td>

</tr>

</table>

Javascript Code:

function lbemployeenamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

function lbadminnamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

function lbreadernamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

(function ($) {

transferManager = function () { }

debugger;

transferManager.performTransfer = function (sender, args) {

var destinationItemIndex = this._getDestinationIndex(args);

var destinationListBox = this._getDestinationListBox(args);

if (destinationListBox == null)

return;

var reorderIndex = args.get_dropPosition() == 0 ?

destinationItemIndex : destinationItemIndex + 1;

var items = args.get_sourceItems();

this._transfer(items, destinationListBox, reorderIndex);

}

transferManager._transfer = function (items, destination, reorderIndex) {

$.each(items, function (index, item) {

item.unselect();

destination.get_items().insert(reorderIndex, item);

});

}

transferManager._getDestinationIndex = function (args) {

var destinationItem = args.get_destinationItem();

if (destinationItem)

return destinationItem.get_index();

return 0;

}

transferManager._getDestinationListBox = function (args) {

var destinationItem = args.get_destinationItem();

if (destinationItem) {

var id = destinationItem.get_listBox().get_id();

return $find(id);

}

var parent = $(args.get_htmlElement()).parent();

if (parent.is(".RadListBox")) {

var id = parent[0].id;

return $find(id);

}

else if (parent.is(".rlbGroup")) {

var id = parent[0].parentNode.id;

return $find(id);

}

})($telerik.$);

anything wrong in this code.

Tanks in Advance
