Change page size on grid with editable column not working

Hi,

I have searched high and low for a solution to this problem, but haven't been able to find answer as yet.

I am trying to fix a bug in an existing application. There is a grid with a column of text-boxes that the user can enter data into. The column is made editable in the grid PreRender event.

Here is the code:

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadGrid ID="TGrid" runat="server" Visible="true" AllowPaging="true" AllowSorting="true"

PageSize="20" ScrollHeight="100px" ViewStateMode="Enabled" OnNeedDataSource="RadGrid1_NeedDataSource"

OnPreRender="RadGrid1_PreRender" AutoGenerateColumns="false" AllowSelection="False"

AllowMultiRowSelection="false" AllowMultiRowEdit="true" >

<MasterTableView runat="server" HeaderStyle-Wrap="False" AllowCustomSorting="true"

AllowMultiColumnSorting="false" RetrieveAllDataFields="false" EnableColumnsViewState="false"

EditFormSettings-EditColumn-Visible="false" AdditionalDataFieldNames="Cow_ID"

DataKeyNames="Cow_ID" EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn DataField="Cow_ID" HeaderText="MiHub ID" DataType="System.Int32"

ReadOnly="true" HeaderStyle-Width="6em" />

<telerik:GridBoundColumn DataField="COW_EID" HeaderText="Electronic ID" DataType="System.String"

ReadOnly="true" HeaderStyle-Width="12em" />

<telerik:GridBoundColumn DataField="COW_LifeId" HeaderText="Birth ID" DataType="System.String"

ReadOnly="true" HeaderStyle-Width="8em" />

<telerik:GridBoundColumn DataField="COW_VID" HeaderText="Current Visual ID" DataType="System.Int32"

ReadOnly="true" HeaderStyle-Width="8em" />

<telerik:GridTemplateColumn DataField="COW_VID" HeaderText="New Visual ID" DataType="System.Int32"

ReadOnly="false" HeaderStyle-Width="15em">

<EditItemTemplate>

<telerik:RadNumericTextBox runat="server" ID="tbNewVisualID" SelectionOnFocus="SelectAll"

AutoPostBack="false" MinValue="0" MaxValue="999999">

<NumberFormat DecimalDigits="0" GroupSeparator="" />

<ClientEvents OnKeyPress="TelerikVisualIDKeyPress" OnValueChanged="TelerikValueChanged" />

</telerik:RadNumericTextBox>

<span class="errorText" style="display: none">*NOT UNIQUE*</span>

</EditItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</div>

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

var data = new List<object>();

for (int i = 0; i < 1000; i++)

{

data.Add(new {Cow_Id = i, Cow_EID = i,cow_LifeId = i, Cow_VID = i});

}

TGrid.DataSource = data;

}

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

foreach (GridItem item in TGrid.MasterTableView.Items)

{

if (item is GridEditableItem)

{

GridEditableItem editableItem = item as GridDataItem;

editableItem.Edit = true;

}

TGrid.Rebind();

}

Running the code shows the editable column correctly, however changing the page size doesn't work as expected. Paging however seems to work fine.

If I comment out TGrid.Rebind();, or editableItem.Edit = true; then changing the page size works as expected, but then the column is not editable. Any thoughts?

Thanks in advance.

How to save Aggregations/Cells attributes when rebind (Client-side)?

Hello,

I work on a Grid and use .Aggregate() and .CellAction() (for cell.HtmlAttributes["style"]).

Everything works except when I rebind the grid on the client-side (after edit, delete, etc.). I lost my aggregations and all my cells style too. How can I keep this parameters during a rebind ?

Here is my grid :

@{

Html.Telerik().Grid(Model)

.Name("Grid")

.DataBinding(dataBinding =>

{

dataBinding.Ajax()

.Select("Select", "MyController")

.Insert("Insert", "MyController")

.Update("Update", "MyController")

.Delete("Delete", "MyController");

})

.ClientEvents(events => events

.OnDataBinding("onDataBinding")

.OnComplete("onComplete")

.OnEdit("onEdit")

.OnRowDataBound("onRowDataBound"))

.Columns(columns =>

{

columns.Command(commands =>

{

commands.Edit().ButtonType(GridButtonType.Image);

commands.Delete().ButtonType(GridButtonType.Image);

}).Width(30); ;

columns.Bound(o => o.Id);

columns.Bound(o => o.col1);

.Aggregate(aggregates => aggregates.Sum())

.GroupFooterTemplate(@<text>@item.Sum</text>);

columns.Bound(o => o.col2)

.Aggregate(aggregates => aggregates.Sum())

.GroupFooterTemplate(@<text>@item.Sum</text>);

columns.Bound(o => o.col3)

.Aggregate(aggregates => aggregates.Sum())

.GroupFooterTemplate(@<text>@item.Sum</text>);

})

.CellAction(cell =>

{

if ((cell.Column.Member == "col1")

{

cell.HtmlAttributes["style"] = "background-color: red";

}

})

.Sortable(sorting => sorting

.SortMode(GridSortMode.MultipleColumn)

)

.Filterable()

.Render();

}

}

Thank in advance for your help,

Alexandre G.

[Solved] Strange UI Skin Error (Not the regular issue of not referencing correctly :)

Hello,

My site wasn't applying Skins.

UPDATE:
I just found that my site doesn't include following css references. A different sample site I made, however, does include this.

I can't find where and how this gets included as I fail to find any difference between the codes/libraries in my working and non working websites.

This is the code that isn't generated in the faulty site: I have also added an image of this code if it helps.
<head>
<link href="/WebSite1/WebResource.axd?d=0i1mhVJ1-dCV5bBQXa0WNXmbYGESRkFTq4w1-p04ECHlsK4EoLUX1v8K-ZEziSa6NLLuG8CQam_hjdn0a-QT8ONr_XN7EfGhnC1BbK_yM-K8wo4J3O3HvSi491O8V-ldsembv4hJx1QV2zWuP_rnWQ2&t=635095910640000000" type="text/css" rel="stylesheet" class="Telerik_stylesheet" /> <link href="/WebSite1/WebResource.axd?d=TmmFO1tq-7uTu5j8SekrhtT8osQVDICIU-WZILvwTtp5huwNHWvgSDpEn1MLG9QybLXZ6_uafB0lE_k2xCKvNKCoWQcyDqsJlB1Q6bZ_zeIiLH_L1HAe1W8TBdRZsDvJfNNOsOjyqep5yJauApJnsBJ3hh1SdpYZo_dmjWVp0zg1&t=635095910640000000" type="text/css" rel="stylesheet" class="Telerik_stylesheet" /> </head>

I have a radgrid that is supposed to be styles according to an embedded skin.

1 - I have added the matching version of the Telerik.web....UI.skins.dll to my bin
2 - I referenced the file
3 - I can see all skins in the "design" mode. I can select a skin and the grid even get those colours (in the design mode)
4 - But at run time, the grid gets data but is displayed as a very raw HTML table.
(Please see attached)

5 - I created a similar grid (using same settings and same methods to populate) for a different website and that works fine! so my referencing must be correct.

My project uses many css files.

So is it possible to override skins by one of those files accidentally?

If so, what should I do?

Is there a way to find it out please?

Please help...

Kind Regards,
Menol

Class to create Radgrid dynamically

I am trying to create a class that will allow me to create a radgrid dynamically. Then i have it load on page_load or page_init and i get the same problem. It creates the grid no problem, but when i click on delete, it deletes one record, and then if i click on delete again, it just refreshes the page and nothing happens. Also if i click on insert, it will insert one record and that's it, and then if i try to insert another record, the last record inserted gets deleted.

Formatting issue with radGrid and GridDateTimeColumn in Internet Explorer 10

Hello everybody,

I am working on an application that was developed using IE 8 and the Q2 2012 AJAX controls (2012.2.607.40)

We have recently upgraded to Internet Explorer 10 and have encountered a number of formatting issues.
Attached are a couple of screen shots - the page as it looks in IE 8 and the same screen in IE 10.

I have tried adjusting the size of the columns but no matter what width they are the DatePicker and TimePicker fields use the entire width which results in the required field validator asterisk being pushed under the control.

<telerik:GridDateTimeColumn DataField="NULLABLE_TIMESHEET_ITEM_DATE" HeaderText="Date"

PickerType="DatePicker" DataFormatString="{0:dd/MM/yyyy}" UniqueName="DateTimeColumEditor">

<HeaderStyle Width="120px" />

</telerik:GridDateTimeColumn>

<telerik:GridDateTimeColumn HeaderText="Start Time" PickerType="TimePicker" DataField="NULLABLE_START_TIME"

UniqueName="StartTimeColumn" DataFormatString="{0:HH:mm}" ColumnEditorID="DateTimeColumEditor">

<HeaderStyle Width="105px" />

</telerik:GridDateTimeColumn>

<telerik:GridDateTimeColumn HeaderText="End Time" PickerType="TimePicker" DataField="NULLABLE_END_TIME"

UniqueName="EndTimeColumn" DataFormatString="{0:HH:mm}" ColumnEditorID="DateTimeColumEditor">

<HeaderStyle Width="105px" />

</telerik:GridDateTimeColumn>

Can anybody suggest a way to control the width of the Date and Time picker fields?

Thanks.

Scheduler Web Part w/Exchange - time zone wrong

I'm using a Scheduler Web Part against Exchange server as it's data source. All calendar events in the web part seem to be presenting in UTC 0 time zone, rather than the local time zone, and I cannot find a way to change this setting.

I did read some API documentation that states in the absence of explicitly setting a time zone for the control, it will default to UTC 0 which is exactly what appears to be happening, however, there is not a settable web part property in the GUI in SharePoint for changing the Time Zone, nor can I figure out how to code it manually.

I've verified the regional settings on my SharePoint server are all correct for our local time.

Any help appreciated!

RadTextBox Clears on Postback while ASP Textbox Doesn't

Hello,

I've come across a strange issue I can't seem to get my head around:

I currently have a Dynamic TabStrip/MultiPageView setup going, which dynamically load controls as tabs are added. I have been replacing the regular ASP TextBox controls with RadTextBox controls, however I have noticed that upon changing tabs back and forth, all information in the RadTextBox controls are erased, while the ASP TextBox controls all stay filled in. I'm curious as to what the difference with the TextBoxes are that might be causing this.

It's a little tricky to get workable code to reproduce this, but from what I can tell changes are lost on any postbacks (placing a RadTextBox outside my tabstrip to test also causes information to be lost)

While I would normally assume this is all due to my lack of understanding of ASP page cycles, the fact that I get the expected behavior with an ASP box but not with a RAD box is confusing. Any help in the right direction or even what I can do to try and isolate the problem would be greatly appreciated.

Thank you.

EDIT:

I've narrowed this down to find that Loading a control seems to break the persistence (although it doesn't seem to matter whether the text boxes are in the control our outside the tabstrip completely - the same thing happens). My understanding is that the ViewState/Postback shouldn't affect text boxes (and they don't affect the regular ones) as per this article here. So on the loading of a control, what's destroying the changes in the RadTextBox, but not destroying the changes in the ASP TextBox?
