Hi there

I am exporting a Grid in Biff Format which is successfully exporting - however I want to allow the user to be able to change values in one column only (e.g column 3)

If the user attempts to changes any other columns they would get a warning from Excel advising them the cell is protected.

I believe this can be done in the "ExcelMLWorkBookCreated" but am not sure what the code needs to be so it can loop through all the columns - below is what I have so far....

Any help much appreciated....

protected void gridPricing_ExportToExcel_ExcelMLWorkBookCreated(object sender, Telerik.Web.UI.GridExcelBuilder.GridExcelMLWorkBookCreatedEventArgs e)

{

e.WorkBook.Worksheets[0].IsProtected = true;

StyleElement protectionStyle = new StyleElement("ProtectionStyle");

protectionStyle.CellProtection.IsProtected = false;

e.WorkBook.Styles.Add(protectionStyle);

foreach (ColumnElement column in e.WorkBook.Worksheets[0].Table.Columns)

{

int columnindex = e.WorkBook.Worksheets[0].Table.Columns.IndexOf(column);

if (columnindex == 3)

{

//code NEEDED in here needs to loop through cells or columns

//and get cellelement or columnelement

// so I can set the cell.stylevalue for this column

}

Value lost on moving to other tabs.

Hi

I have come across a strange behavior with the numerictextbox. There are four radtabs and the second tab has a numerictextbox in it. If I enter something inside it and suddenly move to another tab, value is lost. But if I move to another tab on clicking outside the numerictextbox value persists. Is it a bug?

Thanks
Anu

set_currentPageIndex difficulties

Hello,

I am currently using radgrid client-side databinding, very similar to the example here: http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx

What I want to do is have the user page, sort, filter, select rows, etc and have the server-side code capturing those values in session. If for any reason the page is refreshed, I want to initialize the grid back to those session values (sort/filter/page/selected row).

I can get almost all of this working with the exception of the page index. It appears to work, but then the grid immediately fires a page change back to page 0.

Any insight into why this is happening?

$find fails in javascript for RadNumericTextBox on jquery Document.Ready in IE

Hi,

I need to disable some fields on the client side on page load that I will later enable via JavaScript. Doing this from the server side is not supported so I'm doing this by calling a JavaScript function from the jquery document ready as in:

$(document).ready(function() {

// Handler for .ready() called.

initialize();

//setVisibleMarkers();

alert("document.ready");

enableMailingLabelsButton();

EnableCustomTemplates();

});

the enableMailingLabelsButton is as follows:

function enableMailingLabelsButton()

{

var btnPrintMailingLabels = document.getElementById('<%=btnPrintMailingLabels.ClientID%>');

var btnRefresh = document.getElementById('<%=btnRefresh.ClientID%>');

var ddlMailingList = document.getElementById('<%=ddlMailingList.ClientID %>');

var rdoSelectNew = document.getElementById('<%=rdoSelectNew.ClientID %>');

var rdoSelectDefault = document.getElementById('<%=rdoSelectDefault.ClientID %>');

var rdoSelectDateRange = document.getElementById('<%=rdoSelectDateRange.ClientID %>');

var rdoPreviousDataSet = document.getElementById('<%=rdoPreviousDataSet.ClientID %>');

var txt1ClickNumberToPrint = $find('<%= txt1ClickNumberToPrint.ClientID %>')

var txtDateRangeNumberToPrint = $find('<%= txtDateRangeNumberToPrint.ClientID %>')

var rdiStartDate = $find('<%= rdiStartDate.ClientID %>')

var rdiEndDate = $find('<%= rdiEndDate.ClientID %>')

if (rdoSelectNew.checked == true)

{

//alert(rdiStartDate);

rdiStartDate.disable();

rdiEndDate.disable();

txt1ClickNumberToPrint.disable();

txtDateRangeNumberToPrint.disable();

ddlMailingList.disabled = true;

btnPrintMailingLabels.disabled = true;

btnRefresh.disabled = true;

}

else if (rdoSelectDefault.checked == true)

{

rdiStartDate.disable();

rdiEndDate.disable();

txt1ClickNumberToPrint.enable();

txtDateRangeNumberToPrint.disable();

ddlMailingList.disabled = true;

btnRefresh.disabled = false;

btnPrintMailingLabels.disabled = true;

}

else if (rdoSelectDateRange.checked == true)

{

rdiStartDate.enable();

rdiEndDate.enable();

txt1ClickNumberToPrint.disable();

txtDateRangeNumberToPrint.enable();

ddlMailingList.disabled = true;

btnRefresh.disabled = false;

btnPrintMailingLabels.disabled = true;

}

else if (rdoPreviousDataSet.checked == true)

{

rdiStartDate.disable();

rdiEndDate.disable();

txt1ClickNumberToPrint.disable();

txtDateRangeNumberToPrint.disable();

ddlMailingList.disabled = false;

btnRefresh.disabled = false;

if (ddlMailingList.selectedIndex >= 0 ) {

// alert("making labels active");

btnPrintMailingLabels.disabled = false;

}

else {

// alert("making labels inactive");

btnPrintMailingLabels.disabled = true;

}

The line var txt1ClickNumberToPrint = $find('<%= txt1ClickNumberToPrint.ClientID %>'

)  

shows a null after execution

in the

txt1ClickNumberToPrint field, so when trying to disable this field the javascript throws an error on 

page load and stops executing only in IE 10 on first load.  once the page is loaded things work fine also 

Chrome does not have an issue at all.  I'd appreciate any help.  Here is the markup for that section.

<fieldset style="width:100%;">

<legend>Select Your Data Set:</legend>

<table class="signup-label" cellpadding="5px">

<tr>

<td ><asp:RadioButton Checked="true" runat="server" ID="rdoSelectNew" GroupName="select" /></td>

<tr>

<td align="left" valign="baseline">The most recent <telerik:RadNumericTextbox ID="txt1ClickNumberToPrint" runat="server" NumberFormat-DecimalDigits="0" Width="50px"></telerik:RadNumericTextbox> leads!</td>

Validators won't fire - using demo provided

Using the demo located here:
http://demos.telerik.com/aspnet-ajax/input/examples/common/validation/defaultvb.aspx

The validators are allowing a post back with EnableClientScript = true, despite displaying that there is an error case.

Steps to reproduce:

1) New web form application
2) New web form
3) Copy code into aspx and codebehind
4) Add a radscriptmanager, removing the masterpage reference [which i cannot find a copy of], and removing the asp:content panels
5) Override OnLoad and insert a breakpoint
6) Run the form with client mode on, breakpoint is hit despite all the validators triggering.
7) Repeat tests in all browsers - all fail.
What am I doing wrong?

Update for clarification:
The validators fire, but they still cause a postback (is this intentional?) and server side they do not flag Page.IsValid as true or false.

[Solved] RadGrid Change EditMode OnRowDblClick

Hi,

I have a RadGrid with EditForm Template for Editing.
for Example:
I want to have:
* When I double click a row it has to Change Editmode to:

<MasterTableView EditMode="InPlace"

Like this:

function RowDblClick(sender, eventArgs) {

// insert Code here to change EditMode to EditMode="InPlace"

// then open the row for editing

editedRow = eventArgs.get_itemIndexHierarchical();

$find("<%= RadGrid1.MasterTableView.ClientID %>").editItem(editedRow);

}

hence, the Default mode is the EditForm Template, so when I click on Edit button it will open the form for editing.

any Help it will be apperciated,
Thanks

Selected ListBox items are not shown

I have a RadListBox with multi-select turned on. On selection of another list control, in the code-behind of the other list control, I get its value, then select records from a database, and want to select the corresponding items in the RadListBox (called "listWho" below). When walking thru the code, it is selecting the list box items, but, after postback, the list box shows not selected items. Why?

Here is the code. Any help appreciated. Dan

<telerik:RadListBox ID="listWho" runat="server" DataSourceID="dsScheduleWho" TabIndex="2"

DataTextField="wholist" DataValueField="pk" Height="120px" Width="169px"

Skin="Vista" SelectionMode="Multiple" OnClientLoad="listWho_ClientLoad">

</telerik:RadListBox>

protected void DistGroup_SelectedIndexChanged(object sender, EventArgs e)

{

string itemValue;

DropDownList ddl = sender as DropDownList;

string DG_cpk = ddl.SelectedValue;

try

{

RadListBox rlb = (RadListBox)pageform.FindControl("listWho");

DataAccess sda = new DataAccess();

sda.RunSelectCmd("select cpk_users from users inner join DG_Users_Link DUL on users.CPK_USERS = DUL.Cfk_Users and DUL.DELFLAG=0 "

+ "inner join DistributionGroups DG on DUL.Cfk_DistributionGroups=DG.CPK_DistributionGroups and DG.delflag=0 "

+ "where users.DELFLAG=0 and DG.CPK_DistributionGroups=" + DG_cpk);

if (!sda.blNoRecords)

{

foreach (DataRow dr in sda.dtResult.Rows)

{

itemValue = dr["cpk_users"].ToString();

RadListBoxItem rlbi = rlb.FindItemByValue(itemValue);

rlbi.Selected = true;

}

Ajaxified RadGrid - IE issue

Hi all,

I was hoping someone can point me in the right direction for a very odd error I have encountered with IE.

We are currently using Telerik.Web.UI v2013.1.417.35 on the .NET 3.5 framework. If I try and ajax-ify
my RadGrid, either using the RadAjaxPanel or RadAjaxManager, I can not get the grid's filters or paging buttons to fire the first time I click them. If I click a second time, they respond as expected. I have tried this in Firefox & Chrome and they work perfectly.

If I remove the ajax enabling controls, the filters and paging work on the first click.

Any help would be greatly appreciated.

Thanks,
JE
