ExtractValuesFromItem() only works for RadGrid after fresh page load

Well.

Please notice the bold, italicized line in the function below. It works fine (retrieves NEW, user-modified values from the RadGrid) after a fresh load of the page, but after a postback of the page, it retrieves the OLD values from the RadGrid.

Is there any Telerik-related reason this would happen? I really have no idea why the postback page works differently than the original page load.

private static void CaptureChangesInGrid(RadGrid targetGrid)

{

//Loop through each targetgrid item

foreach (GridDataItem gridRow in targetGrid.MasterTableView.Items)

{

Dictionary<object, object> editDict = new Dictionary<object, object>();

targetGrid.MasterTableView.ExtractValuesFromItem(editDict, (gridRow as GridEditableItem));

foreach (GridColumn column in targetGrid.MasterTableView.Columns)

{

CustomEditableColumn editableCol = column as CustomEditableColumn;

GridEditableColumn editColumn = editableCol as GridEditableColumn;

if (editableCol != null)

{

//Find the edit control in the given row

System.Web.UI.Control editItem = editableCol.FindControlInRow(gridRow);

if (editItem == null)

{

throw new ApplicationException("Unable to find edit control in for column: " + editableCol.HeaderText);

}

editableCol.CheckControlForChange(editItem, GetValueFromDictionary(editableCol, editDict));

}

Does anyone have a better way of retrieving user-entered values on a RadGrid which works after successive postbacks to the page? Or is there a way to fix this?

EnableViewState is enabled for the page.

The data entered is required for modifying the appearance of the page (highlighting for errors in entries, etc.) and thus I cannot have a fresh load performed every time. An undesirable option might be to place any user-edited data into the viewstate and perform a full refresh of the page and replace old data with the saved viewstate data... but that sounds like a lot of additional code for which I really don't have the time to create.

I'll be here all day, talk to me!

Thanks,
Jon

space left at the bottom of raddock

hello,

I have a raddcok dynamically created. I load Usercontrol in that. I put raddock height as auto hence it takes height of usercontrol.

I observed there is some space left at the bottom of raddcock after loading usercontrol. Please see attached image. I tried to use CSS to remove that but didnt helped.

Can you suggest better way to remove that ?

.RadDock

{

height: auto;

margin: 0px 0px 9px 0px;

padding-bottom:0px !important;

border-bottom-width:0px;

}

Can't see Preview tab in RadEditor

Hello

No matter what i change in the EditModes i always see only the Deisgn and HTML mode.. I never see Preview mode whatever i try.

this is our RadEditor code:

<telerik:RadEditor ID="editEditor" runat="server" Width="100%" Height="650px" ToolsWidth="100%" StripFormattingOnPaste="MSWordNoFonts"

OnClientCommandExecuting="OnClientCommandExecuting" EnableEmbeddedSkins="true" EditModes="All"

EnableResize="False" Skin="Web20" OnClientLoad="onEditorLoad" meta:resourcekey="editEditorResource1">

As you can see EditModes is set to "All" but no matter what i change it i always see HTML and Design tabs in bottom of the RadEditor.

Why does this happen?

UPDATE: I was able to get the value of column, but I have another question:

I have the following, how do I open up a link to a new window without getting the "sys.webforms.pagerequestmanagerparsererrorexception: the message received from the server could not be parted" error? I'm trying to assign a http link.

{

if (e.CommandName == "Open")

{

string id = ((GridDataItem)e.Item).GetDataKeyValue("ID").ToString();

string url = GetOpenLink(id);

Response.Write(

"<script>");

Response.Write(

"window.open('" + url + "','_blank')");

Client side radgrid handle row selection by edit link in the row

Hello

My RadGrid is based on following demo.
http://demos.telerik.com/aspnet-ajax/grid/examples/client/insertupdatedelete/defaultcs.aspx
There is no server side events or server side bindings.

It is functional but i want to do following things

I have template columns with edit, delete and other link. When i insert a new row and rebind and repaint on client side the links are not rendered for newly inserted row.
Enable row selection Edit link click that is a template column inside grid

and disable row selection on row click

For all above if i get row object than i can work with it.

I am doing following thing. That works but how to disable row selection? I have onrowselecting event and there i check for eventargs dom to cancel for td but it is throwing an error in the event when i select from below. is there an efficient way?

And in function i have following code

<telerik:GridTemplateColumn>

<ItemTemplate>

<a href="#" onclick="EditPersonClick('<%#DataBinder.Eval(Container.DataItem, "PersonId")%>

','Person');return false;">

Edit

</a>

</ItemTemplate>

</telerik:GridTemplateColumn>

function EditPersonClick(personId) {

var grid = $find(Person_GridFollowUp);

var masterTable = grid.get_masterTableView();

var dataItems = masterTable.get_dataItems();

if (dataItems!=null && dataItems.length > 0) {

for (var i = 0; i < dataItems.length; i++) {

var dbPersonId= dataItems[i].getDataKeyValue("PersonId"

); // primary key

if (dbPersonId== personId) {

var row = dataItems[i];

row.set_selected(true);

return ;

}}}}

document.getElementById(
