[Solved] Client Side Binding - Overriding POST

Hello,

I am trying to override the POST method of the client side functionality on a ListView, but I cannot figure out a way to do it, since apparently there is no event in ClientEvents that's triggered once the items are being requested.
My goal is to pass a parameter to the service.

As an example, I am pointing out the functionality available in RadComboBox, called "OnClientItemsRequesting", in which I am able to get the context and set a custom property, as easily as:

function CountyItemsRequesting(sender, eventArgs) {

var context = eventArgs.get_context();

context.District = $find("<%= ddlDistrict.ClientID %>")._value;

}

My question is:
Is there any way at all to pass a parameter as POST in the ListView control?

Thank you in advance!

RadComboBox OnClientItemDataBound event not firing

Can someone post a complete example of Q2 2011 for making this work .... I have the other events working including OnClientSelectedIndexChanged, OnClientItemsRequesting, OnClientDropDownClosing

My problem is the OnClientItemDataBound event does not seem to be firing ... I have a somewhat 'different' scenario in that the events are wired up in the code behind and the script as well so

so in the page load

void Page_Load()
{
if(!this.IsPostBack)
{
mycombobox.OnClientItemDataBound = "mycombobox_OnClientItemDataBound"
}

RegisterScripts();
}

then register scripts looks like
private void RegisterScripts()
{
StringBuilder sb = new StringBuilder()
sb.AppendLine("function mycombobox_OnClientItemDataBound(sender, args){console.log(sender);}")
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "name", sb.ToString(), true);
}

the 'binding code looks like this'
[item generation code]
mycombobox.DataSource = items;
mycombobox.DataBind()

CDN Fallback!

Hi,

We have Asp.net 4.5 and using Telerik WebUI version 2012.3.1308.45.
Using telerik:RadScriptManager as our main script manager.

Page is loading very slow and We got waiting for ajax.aspnetcdn.com.. message.

How can we create local fall back for JQuery and other JavaScript files required by ajax toolkit?

Best Regards,

[Solved] ClearCheckedItems on client Side

Hello,

Is there a way to replicate the ClearCheckedItems() method on the client side for a radcombobox.

I am able the uncheck all check box using javascript, but if after I hit a button and code to the server code, the Checkbox are still considered checked. Also, if I clear the checked items using the javascript and select other items after, the counter will display a wrong
number of selected items

function radComboBoxLocationSelectedIndexChanged(item) {

resetRadComboboxWithCheckBox('<%=radComboBox1.ClientID %>');

}

function resetRadComboboxWithCheckBox(comboBoxClientId) {

var d = $find(comboBoxClientId);

d.set_text("");

d.clearSelection();

var items = d.get_items();

var itemsCount = items.get_count();

for (var itemIndex = 0; itemIndex < itemsCount; itemIndex++) {

var item = items.getItem(itemIndex);

var chk = getItemCheckBox(item);

if (chk != null) {

chk.checked = false;

}

function getItemCheckBox(item) {

//Get the 'div' representing the current RadComboBox Item.

var itemDiv = item.get_element();

//Get the collection of all 'input' elements in the 'div' (which are contained in the Item).

var inputs = itemDiv.getElementsByTagName("input");

for (var inputIndex = 0; inputIndex < inputs.length; inputIndex++) {

var input = inputs[inputIndex];

//Check the type of the current 'input' element.

if (input.type == "checkbox") {

return input;

}

Any Ideas?

Thanks.

show only certain files in FileExplorer

I would like to use the file explorer to look at the files that I upload. here is the issue I am running into. I only wnat to show the files for a person that are part of that record. So everyone has a record. If they upload files I put the file names in the database along with the ID of person whom uploaded them. Is there a way to only load the files in the file explorer that belong to that person whom uploaded them. Right now I am trying to view them as links and not working so well.
So is there a way to fill the fileExplorer with just the files I am picking in the sql statement.

Current method not working so well as link buttons caus ethey so not persist well in radwindow.

sql = "Select strUrl from PriorServiceUpload where intPriorServiceId = " & myDataTable.Rows(0)(0)

myDataTable = New DataTable

myDataTable = getReader(sql)

If myDataTable.Rows.Count > 0 Then

Dim attach As New LinkButton

For Each row As DataRow In myDataTable.Rows

attach.Text = row(0) & "<br>"

attach.CausesValidation = False

attach.CommandArgument = row(0)

Next

AddHandler attach.Click, AddressOf GetattachLink

phAttach.Controls.Add(attach)

End If

Fileexplorer reload on postback

I have a file explorer on my page that is filtering files based on a sql pull. However what happens is that I use the async uploader to upload files then show in only grid view in the file explorer. When I post back though nothing show in the file explorer, it says no files avialable even though I uploaded files or there where previous files in there.

Protected Sub lnkSubmitRequest_Click(sender As Object, e As EventArgs) Handles lnkSubmitRequest.Click

Code to submit the page

This statment reloads all the information on the page if its changed from the database

LoadPriorService(Convert.ToInt32(HFRecruit.Value))

End If

Private Sub LoadRecruit(ByVal recruitId As Integer)

Reload the page

This statement is where the FileExplorer is located on the LoadPriorService but I have no command to actually reload the control on a postback.

LoadPriorService(recruitId)

Else

ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), "OpenWindow", "NoData();", True)

End If

Private Sub LoadPriorService(ByVal recruit As Integer)

ClearPriorSvc()

sql = "Select intPriorServiceId, intBranchServiceId, dtDischarge, bitSF180, bitStaterequest, bitArpercen, bitredd, strNotes, dtSubmitted, submittedBy, dtCompleted, CompletedBy, strRocComments " _

& "from vw_PriorService where intRecruitId = " & recruit

myDataTable = New DataTable

myDataTable = getReader(sql)

If myDataTable.Rows.Count > 0 Then

HFPriorService.Value = myDataTable.Rows(0)(0)

ddlBranchService.SelectedValue = myDataTable.Rows(0)(1)

txtDtDischarge.Text = myDataTable.Rows(0)(2)

If myDataTable.Rows(0)(3) = "1" Then

cbSF180.Checked = True

End If

If myDataTable.Rows(0)(4) = "1" Then

cbState.Checked = True

End If

If myDataTable.Rows(0)(5) = "1" Then

cbArpercen.Checked = True

End If

If myDataTable.Rows(0)(6) = "1" Then

cbREDD.Checked = True

End If

txtPriorNotes.Text = myDataTable.Rows(0)(7)

lblSubmittedON.Text = myDataTable.Rows(0)(8)

lblSubmittedBy.Text = myDataTable.Rows(0)(9)

lblCompletedOn.Text = myDataTable.Rows(0)(10)

lblCompletedBy.Text = myDataTable.Rows(0)(11)

txtRocNotes.Text = myDataTable.Rows(0)(12)

lnkSubmitRequest.Enabled = True

Else

lblSubmittedON.Text = "None Submitted"

lblSubmittedBy.Text = "None Submitted"

End If

End Sub

Here is the code that loads the fileExplorer, it seems to only load on the initial page loads and bugs out on postback.

Private Sub radFileExplorer_ExplorerPopulated(sender As Object, e As RadFileExplorerPopulatedEventArgs) Handles radExplorer.ExplorerPopulated

'If HFPriorService.Value > "" Then

sql = "Select strUrl from PriorServiceUpload where intPriorServiceId = " & HFPriorService.Value

myDataTable = New DataTable

myDataTable = getReader(sql)

If myDataTable.Rows.Count > 0 Then

If e.ControlName = "grid" Then

Dim items As List(Of FileBrowserItem) = e.List

Dim i As Integer = 0

For Each row As DataRow In myDataTable.Rows

While i < items.Count

If Not items(i).Name.Contains(row(0)) Then

items.Remove(items(i))

Else

i += 1

End If

End While

Next

End If

'End If

End Sub

RadGRid - How to apply fixed column width to some columns

Hi,
One of RadGrids in my application is having large number of columns. TableLayout of MasterTableView is "Fixed".
I have explicitly set width for each column so that when all columns are made visible, they all are displayed correctly.
But by default only few columns are visible and they are automatically expanded to cover whole width of the grid.
I do not want some columns like checkbox columns to expand. I want them to be always of fixed width.
How can I achieve this??

I know this can be achieved by not specifying width of one of the columns, but then that column width reduces to 0 when more number of columns become visible.

Thanks
Tushar

Three-State Checkbox - only two states when clicking?

Hello,

I added some three-state checkboxes like in the demo:

<telerik:RadButton ID="btnToggle" runat="server" ToggleType="CustomToggle" ButtonType="ToggleButton">

<ToggleStates>

<telerik:RadButtonToggleState Text="UnChecked" PrimaryIconCssClass="rbToggleCheckbox" />

<telerik:RadButtonToggleState Text="Filled" PrimaryIconCssClass="rbToggleCheckboxFilled" />

<telerik:RadButtonToggleState Text="Checked" PrimaryIconCssClass="rbToggleCheckboxChecked" />

</ToggleStates>

</telerik:RadButton>

This works fine, but I want to disable the "Filled" state when clicking.
I want to set all three states server-side, but the user shouldn't be able to use the "Filled" state - he should be able to just switch between "unchecked" and "checked".

How can I achieve this?

Thanks!

ItemStyle

Hi,
I am trying to visualize the fact that some dates are unavailable. I first tried to do this in Calendar_DayRender, but I was only able to disable the dates, not colorize them.

I then tried Calendar_PreRender, and added all unavailable dates (with formatting) into the calendars SpecialDays. What happened then was
1. still only disabled, no color.
2. when I go to next month, the backcolor appears. it then stays, and works ok.
3. ForeColor is never set. It seems that <span> overrides the styling. css for span is set by Telerik.

Any suggestions on how to fix this?
