radlistbox

I'm loading ralistbox items from db and I have all 4 buttons working but when I do a single transfer to right or left it gives a js error object reference not set to an instance of an object but it updates correctly on db, but due to this error I have to refresh the page.

if (e.Items.Count == 1 && e.SourceListBox == RadListBox1)// if selected item count is 1 and sourcelistbox is Radlistbox1

{

SelectedItem.Append("<li> Texto : " + e.Items[0].Text + " ID : " + e.Items[0].Value + "</li>");

BLL.Patrocinadores.Adicionar1PatrocinadorAoAtleta(id_atleta, id_patrocinador); // add one sponsor to user

lblTransfer.Text = SelectedItem.ToString();

ActualizarListas();

// mensagem = lblTransfer.Text;

// logger(mensagem);

}

// getting id with

id_patrocinador = Convert.ToInt32(RadListBox2.SelectedValue.ToString());

any idea for fix?

RadGrid and DetailTables

Hi all!

I've a RadGrid with a detail table collapsed by default.

I noticed that my fist click to expand the detail table doesn't works. No matter where is the first click, I just have to click in the expand one type in any row. That click doesn't works but all following clicks do work.

I debugged and notice that a postback is made in the first click, thus I don't understand why, even with a postback, the grid doesn't update showing the detail table.

RadWindow opens content only at the first time

I use this code to display different divs in RadWindows:


var wnd = window.radopen(null, "modalWindowWithContent");

wnd.set_contentElement($get(contentElement));

wnd.setSize(wndWidth, wndHeight);

wnd.center();

return wnd;

where contentElement is the names of the divs.

AT the first time all works perfect but at the second (and further) time the RadWindow opens but with a blank content. I see in the Firebug that the content of the second div is loaded in the content of the first loaded div and this content (the first) is unvisible.

How can I fix it?

Buttons in RadWindow cause unwanted postback

Hi,

I have a run-time generated RadWindow that has a variety of controls in it. The RadWindow opens correctly when triggered, but when one of the buttons in the RadWindow is pressed, it causes postback, which wipes out the RadWindow.

How can I get client side Javascript to work without posting back to server?

Below is the EditText sub that is called when a button is pressed that should open the RadWindow with the RadEditor in it. When either the Save or Add button is pressed, the RadWindow disappears, and it doesn't look like it hits the Javascript functions.

Below that is the html for the page including some rudimentary javascript functions at the bottom I am trying to use to test this.

Thanks so much for looking at this!

aspx.vb

Private Sub EditText(ByVal sender As Object, ByVal e As System.EventArgs)

Dim buttonId As String

Dim x As Integer

Dim AN As Integer

If C.UserSelectedAssessmentType = "CREATE" Then

AN = C.UserSelectedAssessmentCount

Else

AN = C.UserSelectedAssessment

End If

buttonId = DirectCast(sender, RadButton).ID

x = Mid(buttonId & " ", 8, 2)

EditingStatement = x

w1.ContentContainer.Controls.Add(New LiteralControl("<div><table style=""width:725px""><tr><td>"))

editL1.Text = "Use this editor"

w1.ContentContainer.Controls.Add(editL1)

w1.ContentContainer.Controls.Add(New LiteralControl("</td><td style=""text-align:right"">"))

editSave.AutoPostBack = False

editSave.CausesValidation = False

editSave.OnClientClicked = "EditClickSave"

editSave.ID = "editSave"

editSave.Text = "Save"

editSave.Width = 128

w1.ContentContainer.Controls.Add(editSave)

' AddHandler editSave.Click, AddressOf Me.SaveEdit

w1.ContentContainer.Controls.Add(New LiteralControl("</td></tr></table>"))

popupEditor.ID = "Editor1"

popupEditor.Width = 725

popupEditor.Height = 350

popupEditor.EditModes = EditModes.Design

w1.ContentContainer.Controls.Add(popupEditor)

editL2.Text = "Choose Item"

w1.ContentContainer.Controls.Add(editL2)

w1.ContentContainer.Controls.Add(New LiteralControl("<br />"))

editCombo.ID = "editFindings"

editCombo.Width = 410

w1.ContentContainer.Controls.Add(editCombo)

editAdd.AutoPostBack = False

editAdd.CausesValidation = False

editAdd.OnClientClicked = "EditClickAdd"

editAdd.ID = "editAdd"

editAdd.Text = "Add"

editAdd.Width = 128

w1.ContentContainer.Controls.Add(New LiteralControl("<br /></div>"))

w1.VisibleOnPageLoad = True

w1.Modal = True

w1.Height = 550

w1.Width = 800

column headers not scrolling with data on hoizontal scroll in radgrid after integrating with CRM 2011

I have a web page that primarily contains a telerik radgrid. There are 30 grid bound columns in it. So we are displaying a horizontal scroll bar, by setting Scrolling-AllowScroll ="true"Scrolling-UseStaticHeaders="true"

when we browe the page, everything is wroking fine. Horizontal scroll is moving the column headers along with data and vertical scroll is keeping the column headers static.

In CRM we added a subarea and loading the page. In CRM, the column headers are static for horizontal scroll, which is not correct. Also, it is noticed that after a postback or refresh happens, it starts working fine. We tried to explicity invoke postback and refresh but in vain.

Please help me fix the issue.

Multi-column headers - Export to CSV missing column names

I'm using Version: 2012.1.215.35 and I'm trying to create a grid that has multi-column headers that span 2 columns. I want to be able to export this grid to CSV and I'm running into problems.

The column names are missing

The values are all together without being separated by commas. (e.g. "25 25%")

Here is my front end code:

<telerik:GridTemplateColumn ItemStyle-CssClass="rollupItem" HeaderStyle-CssClass="rgHeader rollupHeader" UniqueName="TemplateColumn">

<HeaderTemplate>

<table id="ContactTableHeader" cellspacing="0" cellpadding="0" width="100%" border="0">

<tr class="rollupTopHeader">

<td colspan="2" align="center">

<asp:Label ID="hasReceived" runat="server" Text='Has Received Prior'></asp:Label>

</td>

</tr>

<tr class="rollupBottomHeader">

<td width="16%" align="center">

<asp:Label ID="hasReceivedTreatmentCountLabel" runat="server" Text='Count'></asp:Label>

</td>

<td width="16%" align="center">

<asp:Label ID="hasReceivedTreatmentPercentLabel" runat="server" Text='Percent'></asp:Label>

</td

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table id="ContactRelationshipTable" cellspacing="0" cellpadding="0" width="100%" border="0">

<tr class="rollupData">

<td width="16%">

<asp:Label ID="hasReceivedTreatmentCount" runat="server" Text='<%# Eval("HasReceivedTreatmentCount") %>'></asp:Label>

</td>

<td width="16%">

<asp:Label ID="hasReceivedTreatmentPercent" runat="server" Text='<%# Eval("HasReceivedTreatmentPercent") %>'></asp:Label

</td

</tr>

</table>

</ItemTemplate>

</telerik:GridTemplateColumn>

Back end code:

protected void ExportToCSVButton_Click(object sender, System.Web.UI.ImageClickEventArgs e)

{

try

{

RollupReportRadGrid.ExportSettings.ExportOnlyData = false;

RollupReportRadGrid.MasterTableView.ExportToCSV();

}

catch (Exception ex)

{

GenericException.HandleException(ex);

Response.Redirect("~/GenericError.aspx");

}

Can someone help with this problem?

Thanks,

Column Center-Right Align Content

Hi All,

I have a GridBoundColumn with numbers in it. Is it at all possible to center the numbers in the column, but right align them, so that the are all lined up, down the column? For example the decimal place of each number is in the same spot regardless of the overall length of the number.

Thanks,
Mark
