[Solved] How to minimize the page size with bit heavy content in the editor

I have a functionality where i am generating html from word document and saving it in database.
Then for some tokenization i am loading it into telerik text editor and doing some tokenization on the content in the editor.
I have read that if there is more then 100KB of content then editor might get slow.I have more then that size of content some time.
So please suggest me how to optimized it to maximum level.My current mark up of the editor declaration is

<telerik:RadEditor runat="server" ID="RadEditor1" Height="515" Width="100%" Visible="True" EnableViewState="False"

ContentFilters=

"ConvertToXhtml, RemoveScripts,FixUlBoldItalic, IECleanAnchors, FixEnclosingP, MozEmStrong,IndentHTMLContent, OptimizeSpans"

>

</telerik:RadEditor>

I have myself set enable viewstate to false to save some space at the moment

Radcombobox enabled/disabled onload via javascript

Hi,

I really need to enabled/disabled the RadComboBox via Javascript when the page is load. I need to do it so I can enable / disable the combobox again when the user click another button via JavaScript. I dont want to postback.

I have put the following code in the Page_Init()

ClientScript.RegisterStartupScript(Page.GetType(),

"mykey", "ToggleRadcomboBox();", true);

The javascript is as follow
function ToggleRadcomboBox()
{
    var combo = $find("<%= RadComboBox1.ClientID %>");
    //the combo return null
    combo.set_enabled(false);
    return false;
}

The above code will return me with "null value",
but, when I used:
function ToggleRadcomboBox()
{
    var combo = document.getElementByID("<%= RadComboBox1.ClientID %>");
    // found combo, but unable to do anything
    // combo.set_enabled(false) does not work when using document.getElementByID
    combo.disabled = true;
    return false;
}

Could you please help me out ?

Thanks.

Strange behaviour on toggle checkbox button with images

I use the following RadButton on a couple of pages and it behave strangely on each page.

<style type="text/css">

.rbBlue .rbText {

color: blue;

}

.rbRed .rbText {

color: red;

}

</style>

<telerik:RadButton ID="FillerNLF" runat="server" AutoPostBack="false" Text="NLF" ButtonType="ToggleButton" checked="false"

ToggleType="CheckBox" Style="font-size: 14px; top: 30px; left: 4px; position: absolute;">

<ToggleStates>

<telerik:RadButtonToggleState PrimaryIconUrl="../Images/layer_transparent.jpeg" CssClass="rbBlue" />

<telerik:RadButtonToggleState PrimaryIconCssClass="rbOk" Selected="true" CssClass="rbRed" />

</ToggleStates>

</telerik:RadButton>

On page 1, I use this and the behavior is fine. When the checkbox is unchecked, the text is blue colored and it is a transparent icon shown. When the checkbox is checked, the green checkmark appears and color of the text is red. That is the proper behavior.

When I use the exact same button on another page, I am getting a square outline of the layer_transparent.jpeg file when it is unchecked. If I hover the mouse over the item, the square outline disappears and nothing is displayed, except the blue text. When the checkbox is checked, a green checkbox appears and the text is red. So, it is the unchecked behavior that is not working. It's for this page only. I noticed this as I am building the page and there is no logic in the codebehind.

[Solved] Reading read only column in ragdrid update

I am using EditMode="InPlace" and AllowMultiRowEdit="True" to edit a RadGrid. I am also using a non RadGrid button to save the RadGrid to a database. Column1 in the RadGrid is read only. I am using ExtractValuesFromItem(newValues, editedItem) to get the cell that was changed. This works, but I don't know how to reference the value in the read only cell in column1 to see which row was edited. I need this to update the database based on the read only information in Column1. I will also be adding databound dropdown lists in the EditItem template so a solution that drastically changes the code below also needs to be able to handle that.

protected void SaveButton_Click(object sender, EventArgs e)

{

foreach (GridItem item in RadGrid1.Items)

{

if (item.IsInEditMode)

{

GridEditableItem editedItem = (GridEditableItem)item;

Hashtable newValues = new Hashtable();

editedItem.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

// I need to get the value in Column1 on the edited row.

string ReadOnlyCell = ["Column1"].toString();

string ChangedCell = newValues["Column2"].ToString();

// will update SQL here...

editedItem.Edit = false;

}

RadGrid1.Rebind();

}

Radgrid & IE10

Hi All:

We have a rather large project where we are using RadGrid from Telerik 2011.1.519.35. We are having a problem with IE10 where the RadGrid will only resolve / appear to about half it's width (i.e., we have one-half of the grid appearing). IE10 then locks up.

We are not having this problem with any other browser (including earlier versions of IE). Unfortunately, while we use Chrome for internal users of our system, we cannot control what browser is used by external users.

We make heavy use of Telerik controls in our application and updating to a more recent version will require a large amount of recursion testing before we could roll out a new version of the dlls.

Is there any workaround to this, or is our only recourse to update to the latest version of Telerik?

Thanks for your help in this matter.

RadGrid inside ServerControl and LinkButton.Click ...

Good Afternoon,

I had the idea of including a RadGrid control inside a custom server control ( reusable on various sites ) and everything works just peachy apart the .Click event of a LinkButton in a TemplateColumn that I can't seem to intercept !

The layout is as follows:

aspx
asp:Panel
MyControl
telerik:RadGrid
MasterTableView
GridTemplateColumn
LinkButton

The LinkButton is created on fly during the RadGrid.ItemDataBound event and added to the columns control collection via:

Dim o_LineDeleteItem As New LinkButton With {.Text = "Del", .ID = String.Format("Delete|" & __Item.DataItem("slc_ID").ToString), .CommandName = "DeleteLineItem", .CommandArgument = __Item.DataItem("slc_ID").ToString}

__Item("Options").Controls.Add(o_LineDeleteItem)

I have tried with/without AddHandler and whatnot, can't seem to get it to work.

The Panel is ajaxified via a RadAjaxManagerProxy and has a RadAjaxLoadingPanel that correctly shows when I click the LinkButton in the grid ... but for some reason I am unable to either get the RadGrid.ItemCommand or LinkButton.Click event to fire to actually do something when the button was clicked.

I tried if many different ways, but this being my first such implementation I most certainly miss something ( more or less ) important.

Any clues on this ?

PS: I looked thru the documentation and searched the www ... to no avail.
