[Solved] Raddock Title Not Shown in Firefox

Hello,

I have a RadDock control wrapped in a usercontrol, Dashboard1.

Dashboard1 is on a page with a DetailsView that allows a user to setup information about their dashboard, such as Name and Description.

The requirement is that the 'dashboard' is hidden until the user clicks the 'Edit' button on the DetailsView. ( this.Dashboard1.Visible = this.dvDashboard.CurrentMode == DetailsViewMode.Edit;)

However, when the edit button is clicked and the dashboard is set to visible, in FireFox the Title is not shown.

The HTML output looks as follows:
<div class="rdTitleBar rdDraggable" id="ctl00_ContentPlaceHolder1_Dashboard1_RadDock86824b65a96a5a46c1aa890a1f01e87b0292_T" style="cursor: move;">
<em style="width: 0px;">Weather</em>

It's the width:0px that FireFox dislikes. I was wondering what circumstances would cause this with to be 0 (until the dock is moved and the title then appears).

[Solved] GridClientSelectColumn and highlighting issue

hi together,

i have a grid on my page which uses multi row selection (with help of a GridClientSelectColumn) and highlighting.
the options for AllowMultiRowSelection and AllowRowSelect are set to "true", UseClientSelectColumnOnly is set to "false".

everything works as supposed except for one thing: everytime i click on one of the checkboxes, the complete row becomes highlighted. i'd like to have the highlight feature exclusively by clicking in the row, not on the checkboxes.

is there a built-in way to highlight only the last selected row and do multi row selection with the checkboxes without highlighting?? i think it's the same way the radtreeview works...
if that's not the case, which event do i hang on to cancel the checkbox highlighting on my own ?

thanks for your help :) regards
hendrik

Paste from Word: format lost after preview click

Hi,

I have upgraded the telerik controls version from 2010.3.929.35 to version 2010.3.1317.35.

In Current version(2010.3.1317.35), when we copy the content from word document and Paste the clipboard data to Radeditor control by only Paste command(Not the Paste from word, only using Paste (CTRL +V)),
Then after by showing the HTML view or Preview the content, the actual view which is pasted is lost and all are goes left aligned, and aslo STYLE attribut from page also removed.

And also Disableing the ConvertToXhtml is not working.

This above problem is not happening in Previous version (2010.3.929.35).

Please see the attached screen shot.

Building a gridview from several databasetables

Hi,

I'm building a grid dynamically from several database tables.
Tables:
* Groups (used to group columns)
* Columns

And datatables, to support data in the structure.

One column can only be member of one group.. but a group can contain several columns.
In the Grid this will be viewed with two column headers, where the group header uses columnspan to span over the columns within the group.
A column contains datatype, format, width and alignment.
So far so good...

I managed to create a grid looking like it should with the column headers and groupheaders. I used the PreRender event to add a second header.

I also added all necessary data to the extendedproperties on the datatable (the datatable is dynamically buildt to support the dynamic setup). So this would be available for me when rendering the grid.

But my problem starts when i wanted to format the data within the cells/columns. One of the column had the type DateTime and the format "{0:dd.MM}" (want to show day and month only). I tried to set the DataFormatString in the PreRender Event for the column, but it still shows the whole date and time.
How can i solve this? This is the code i hardcoded into the prerender event to test this:

((GridBoundColumn)RadGrid1.MasterTableView.GetColumn("to.date")).DataType = Type.GetType("System.DateTime");

((GridBoundColumn)RadGrid1.MasterTableView.GetColumn("to.date")).DataFormatString = "{0:dd.MM}";

I'm not able to set the alignment for the column either. I can set it for the columnheaders, but i think that is because i have the cell object for each header. I want to be able to set both the format and the alignment for the column some place...

Some of the columns can have a flag saying that if the value drops below zero we want to display zero or blank. Is there anywhere this can be set. And remember, i don't know the name of the column before runtime.

And one other thing: How can i add a "grand total" row at the end summarizing only the columns marked for it? (eg: column3, column4 and column5 should be summarized, but not column1 and column2).

Regards

multiselect + loadondemand

Working with 2008.2.1001.35

Main Idea : provide the ability to multi select values in radcombobox but allow to loadondemand
Secondary : update the number of selected item, current text is the first selected item in radcombobox

Main problem : on item request, we cannot get selected item"s".

Workaround :

Part 1 : implementing multi select and loadOnDemand at the same time
Tricky parts : rebind each item after getting datasource, binding values are Text and Value (names of radcomboboxitem), which are not the names in the datasource's header.

Aspx

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"

[...]

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function StopPropagation(e) {

e.cancelBubble = true;

if (e.stopPropagation) {

e.stopPropagation();

}

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

var combo = $find("<%= multiselectTitle.ClientID %>");

var newText = "";

var cnt = 0;

var items = combo.get_items();

var first = false;

var firstItem = "";

for (var i = 0; i < items.get_count(); i++) {

var item = items.getItem(i);

var checkbox = item.get_element().getElementsByTagName("input")[0];

if (checkbox.checked) {

if (first == false) {

firstItem = item.get_text();

first = true;

}

newText += item.get_value() + ";";

cnt++;

}

ajaxManager.ajaxRequest(newText);

combo.set_value(newText);

combo.set_text(firstItem);

document.getElementById("ctl00_contentPlaceHolder_div_count").innerHTML = cnt;

}

[...]

<div id="div_count" runat="server">0</div>

[...]

<telerik:RadComboBox ID="multiselectTitle" runat="server" EnableLoadOnDemand="true" AutoPostBack="false" DataTextField="Title" DataValueField="Id" OnItemsRequested="multiselectTitle_ItemsRequested">

<ItemTemplate>

<div id="div1" onclick="StopPropagation(event)">

<asp:CheckBox ID="chkBoxPrdTitle" runat="server" value='<%# DataBinder.Eval(Container, "Value") %>' />

<asp:Literal ID="litPrdTitle" runat="server" Text='<%# DataBinder.Eval(Container, "Text") %>'></asp:Literal>

</div>

</ItemTemplate>

</telerik:RadComboBox>

[...]

Code behind

private void resetSelectedPrdIds()

{

Session["selectedPrdIds"] = null;

div_count.InnerHtml = "0";

multiselectTitle.Text = "";

}

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

resetSelectedPrdIds();

}

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] values = e.Argument.Split(';');

List<int> ids = new List<int>();

foreach (string value in values)

{

try { ids.Add(int.Parse(value)); }

catch { }

}

Session["selectedPrdIds"] = ids;

}

protected void multiselectTitle_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

RadComboBox comboBox = (RadComboBox)sender;

List<int> selectedPrdIds = new List<int>();

if (Session["selectedPrdIds"] != null)

selectedPrdIds = (List<int>)Session["selectedPrdIds"];

var itemObjects = from items in myDataContext

where (SqlMethods.Like(items.title, e.Text + "%") ||

(from vals in selectedPrdIds select vals).Contains(items.id))

select new { Id = items.id, Title = items.title };

foreach(var io in itemObjects)

{

comboBox.Items.Add(new RadComboBoxItem(io.Title, io.Id.ToString()));

}

RadComboBoxItemCollection rcbic = multiselectTitle.Items;

foreach (RadComboBoxItem item in rcbic)

{

if (selectedPrdIds.Contains(int.Parse(item.Value)))

{

((CheckBox)item.FindControl("chkBoxPrdTitle")).Checked = true;

}

item.DataBind();

}

SkinManager and standard CSS style sheets

We have just started converting all of our asp:textbox to telerik:radTextBox. We created a standard css file (used for all aspx pages) so we could set the width's for different boxes based on usage. Example, a box for state only needs to be 2 characters wide (about 20-30px). The skin manager overrides the cssclass property setting for the telerik boxes, setting all boxes to the same width. How can I still use a custom style sheet to set width's and the skinmanager at the same time?

RadAjaxManager & RadGrid Dynamic LinkButtons Error

Hello,

I have a form with a RadScriptManger, RadAjaxManager, and RadGrid.

One of the columns of the RadGrid loads a dynamic linkbutton that I want to pop-up an Open/Save File Dialogue box. It works without the RadAjaxManager, but with it I get this error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Which is correct, I subscribe each dynamic link button to the following click event that modifies the Response,

Protected Sub onClick(ByVal sender As Object, ByVal e As EventArgs)

Try

Dim NewButton As LinkButton = CType(sender, LinkButton)

Dim con As New SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("NBOConnectionString").ConnectionString)

Dim cmd As New SqlClient.SqlCommand("Select Id, NDAId, FileName, [File], FileType FROM NDA_Files Where Id = " & Convert.ToInt32(NewButton.ToolTip), con)

Dim da As New SqlClient.SqlDataAdapter(cmd)

con.Open()

Dim dt As New Data.DataTable

da.Fill(dt)

For Each row As Data.DataRow In dt.Rows

With row

Dim DataFile() As Byte

DataFile = .Item("File")

HttpContext.Current.Response.Buffer = True

HttpContext.Current.Response.ContentType = .Item("FileType")

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" & .Item("FileName"))

HttpContext.Current.Response.AppendHeader("Content-Length", DataFile.Length.ToString())

HttpContext.Current.Response.BinaryWrite(DataFile)

End With

Next

I searched around and found this article:
http://weblogs.asp.net/leftslipper/archive/2007/02/26/sys-webforms-pagerequestmanagerparsererrorexception-what-it-is-and-how-to-avoid-it.aspx

Towards the bottom of that, there is this solution:
Call ScriptManager.RegisterPostBackControl() and pass in the button in question. This is the best solution for controls that are added dynamically, such as those inside a repeating template.

I didn't see "RegisterPostBackControl()" within the RadScriptManager so I added .NETs script manager and added a section in my RadGridItemDataBound procedure to add the dynamic linkbuttons to this as show below:

For Each Control In e.Item.Controls

If CType(Control, Telerik.Web.UI.GridTableCell).Controls.Count > 2 Then

If CType(Control, Telerik.Web.UI.GridTableCell).Controls(1).GetType.Name = "LinkButton" Then

Dim lnkButton As LinkButton = CType(CType(Control, Telerik.Web.UI.GridTableCell).Controls(1), LinkButton)

ScriptManager1.RegisterPostBackControl(lnkButton)

End If

Next

Which finds the LinkButtons and adds them with no errors.....However when I click the linkbutton I still get the error.
Is there any better way to get this functionality?

Either I need to figure out how to exclude the linkbuttons from the AJAX call, or a way to make the pop-up work without using the Response. Any Ideas?

Thanks,

Coty
