Telerik Grid, GridClientSelectColumn bind data

Hi Telerik Team,

I am working on the Telerik Grid, my first column in that grid is "GridClientSelectColumn", with which I am able to 'check' the required row and save to the database, but I could not bind the saved items to that "GridClientSelectColumn". Below is the sample code which I am using.

1. In Aspx Page

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="true"

AllowAutomaticUpdates="True" PageSize="10" Width="100%" AutoGenerateColumns="false"

AllowMultiRowSelection="true" DataSourceID="sds_Reconcile" onitemcreated="RadGrid1_ItemCreated"

OnItemDataBound="RadGrid1_ItemDataBound" OnPreRender="RadGrid1_PreRender">

<telerik:GridClientSelectColumn DataTextField="pvkey" Text="select" UniqueName="column1"

HeaderText="Select"> </telerik:GridClientSelectColumn>
...
</Columns>
2. C# Code
a. In ItemDataBound and ItemCreated i have used this code

if (e.Item is GridDataItem) {

GridDataItem item = (GridDataItem)e.Item;

if (item.OwnerTableView.Name == "Table") {

if (item["is_recon"].Text == "True") {

CheckBox chkbx = (CheckBox)item["column1"].Controls[0];

chkbx.Checked =

true;

e.Item.BackColor = System.Drawing.

ColorTranslator.FromHtml("green"); }}}

b. In PreRender, I am using this code

foreach

(GridDataItem dataItem in this.RadGrid1.MasterTableView.Items)

{

if (dataItem["is_recon"].Text == "True")

{

CheckBox chkbx = (CheckBox)dataItem["column1"].Controls[0];

chkbx.Checked =

true;

}

dataItem["column1"].BackColor = System.Drawing.Color.Gray;

}

I am able to get the correct values from the database, and they are executing with the chkbx.Checked = true. But I could not see the items checked in the webpage when they are loaded.

And also I am using Default skin, and assigning my custom css to that Grid, with which I am unable to color the row. (dataItem["column1"].BackColor = System.Drawing.Color.Gray;)

Thanks
Mark

Download File in Content Page

Dear developers hello,

I use RadExplorer, in my classic website, with the option to download (or open) files with double click. It works great.

Now i changed my pages and i use Master and Content pages, instead of classic.
RadExplorer is in the Content Page of a Master Page.
After that change, the download is not working. I double click the file and it does nothing (download or open).
The file Handler.ashx is the same.

I use:
Visual Studio 2008 v9.0.30729.1 SP (ASP.NET Visual Basic)

RadControls for ASP.NET Ajax 2010.2.929.35 Trial

Windows 7

If you need any other information, please let me know.
Thank you in advance for your time.

Best Regards

Open RadWindow Client Side

I am trying to open my radwindow from client-side but this window opens when I set my linkbutton onclientclick event handler, window is opening fine. But when I try to open my radwindow using Page.ClientScript I can't see my radwindow. Any help would be really appreciable. I don't want to set VisibleOnPageLoad=true because I have multiple radwindows and if any button clicks all window will appear in the screen.

Disable others appointment

Hi,
I am developing telerik Radscheduler in which there are multiple users who login into the scheduler.
I want to design the system in a way where one user can only insert or delete only his appointment and cannot touch other's appointment. He/she should be disabled from touching others appointments...How do I do that?
Code snippet would be appreciated.

using OnClientLoad method (window.open logic inside)

Hi,

I am using extensions\wpresources\RadEditorSharePoint\4.5.4.0__1f131a624888eeed .
In moss, I want implement popup new windows for Links inside rad editor, I want to mention custom width n height ( They may chage in next developemnt)

trial -1:
I tried to use window.open directly inside radwindow bt it didn't worked out, this piece of code striping by itself.

trial -2

I gone through yur foum and you are using OnclientLoad javascript method for window.open

So I tried to implement it. see below :

On page layout
<script type="text/javascript">
function OnClientLoad(editor)
   {
   editor.attachEventHandler ("onclick", function (e)
   {
   var sel = editor.getSelectedElement(); ; //get the currently selected element
   var href = null;
   var ele = document.getElementById("popupwindow");
if (ele)
{
if (sel.tagName == "A")
{
href = sel.href; //get the href value of the selected link
window.open(href, null, "height=500,width=500,status=no,toolbar=no,menubar=no,location=no");
return false;
}
   }
   });
   }
   </script>

For telerik:
<telerik:RadHtmlField id="pagecontent" FieldName="PublishingPageContent" runat="server" AllowSpecialTags="true" OnClientLoad="OnClientLoad"/>

URl link will be like this, in HTML mode rad-
<div id = "popupwindow">
<a href blah blah>
</div>
But I am getting an error :
An error occurred during the processing of . Type 'Telerik.SharePoint.FieldEditor.RadHtmlField' does not have a public property named 'OnClientLoad'.

Trial -3 :

In configfile.xml : I added <property name="OnClientLoad">OnClientLoad</property>
still I am getting error: -> does not have a public property named 'OnClientLoad'.

Any suggestions??? Is there any way i can implement these popup links with custom width n height inside rad editor?

Filter Not Working:

Hi,

I'm having some problems with creating a custom filter control for something that I would assume is easy to do. I have created another in the project that is bound to a enum that works fine, but this filter which is bound to a class is failing:

The error

The markup

<uc:OrderStatusFilterColumn AllowFiltering="true" AutoPostBackOnFilter="true" DataField="Status" HeaderText="Status" ShowFilterIcon="false"

UniqueName="Status" >

<ItemTemplate>

<%# DirectCast(Container.DataItem, Quote).Status.Name%>

</ItemTemplate>

</uc:OrderStatusFilterColumn>

the custom control

For Each currentStatus As Status In Status.GetAllStatus()

combo.Items.Add(New RadComboBoxItem With {.Text = currentStatus.Name, .Value = CStr(currentStatus.StatusID)})

Next

AddHandler combo.SelectedIndexChanged, AddressOf comboSelectionChanged

End Sub

Renaming tabs

Greetings! I am trying to create a tabstrip that allows users to add, remove and rename their tabs. The add and remove are fairly straightforward, but I'm wondering if anyone has come up with a more elegant way to do the rename.

I was hoping for something along the lines of the treeview control which allows inline editing of the label, but I don't see this in regard to tabs. I can "fake it" by putting an editable field in the tab or creating a prompt, but I am hoping I'm missing something and it's easier than this.

Any suggestions are much appreciated!
