[Solved] Problem With Auto Selecting Node

I think I found a possible bug with the Drop Down Tree and setting the default selected value. I followed this link I created a few months ago and just found this issue now.

I have a tree that looks like this:
- Grades          //ID: 0, Parent: null, Value: 0
-- Random          //ID: 1, Parent: 0, Value: 2
--- J          //ID: 2, Parent: 1, Value: 7
--- Prime          //ID: 3, Parent: 1, Value: 8
--- A          //ID: 4, Parent: 1, Value: 9
--- 2 & Better          //ID: 5, Parent: 1, Value: 10
--- 2          //ID: 6, Parent: 1, Value: 11
--- Select          //ID: 7, Parent: 1, Value: 12
-- Fixed          //ID: 8, Parent: 0, Value: 1
--- J          //ID: 9, Parent: 8, Value: 1
--- Prime          //ID: 10, Parent: 8, Value: 2
--- A          //ID: 11, Parent: 8, Value: 3
--- S          //ID: 12, Parent: 8, Value: 4
--- Econ          //ID: 13, Parent: 8, Value: 5

As you can see, there are duplicate text (I only allow the selection of the child elements - "Grades", "Random" and "Fixed" are not allowed as they are the root or are types). So if I have:

RadDropDownTree.SelectedValue = "2";

RadDropDownTree.SelectedText = "Prime"

and for some reason the "Prime" under "Random" is selected, when the "Prime" under "Fixed" SHOULD be selected. Does that make sense?

It appears that the SelectedText property selects the first text value that matches the input and does not respect the SelectedValue. Is there a way I can fix this?

Grid not binding after filtering

Hi.

I'm noticing something weird happening with a telerik grid. Short version is that when I filter it, I'm seeing an error that indicates there are no rows to display, despite me being able to see in the code that there is data there...

I have filter controls outside of the grid, it's a big page so I was trying to simplify it for my users

my drop down looks like this, it is databound in the code behind

<telerik:RadComboBox ID="ddlCompany" runat="server" Visible="False" AutoPostBack="True" DataValueField="CompanyID"

DataTextField="Name" OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged" >

<Items>

</Items>

</telerik:RadComboBox>

my grid looks like this

<telerik:RadGrid ID="productionSearchResults" runat="server" AutoGenerateColumns="false" CellPadding="0" Skin="Windows7" EnableLinqExpressions="false" Width="100%"

AllowPaging="true" AllowSorting="true" AllowFilteringByColumn="true" GridLines="None" PageSize="100" OnItemDataBound="productionSearchResults_ItemDataBound"

AllowCustomPaging="true">

<HeaderContextMenu EnableAutoScroll="True" />

<HeaderStyle Font-Names="Verdana" />

<AlternatingItemStyle Font-Names="Verdana" />

<ItemStyle Font-Names="Verdana" />

<PagerStyle AlwaysVisible="True" />

<GroupingSettings CaseSensitive="false" />

<ClientSettings>

<ClientEvents OnGridCreated="SizeGridToVerticalContent" />

<Scrolling UseStaticHeaders="true" AllowScroll="true" FrozenColumnsCount="0" />

</ClientSettings>

<MasterTableView CommandItemDisplay="Top" Width="98%">

<CommandItemSettings

ShowAddNewRecordButton="false" ShowRefreshButton="false"

ShowExportToWordButton="true" ExportToWordText="Export results to Word"

ShowExportToExcelButton="true" ExportToExcelText="Export results to Excel"

ShowExportToCsvButton="false" ExportToCsvText="Export results to CSV"

ShowExportToPdfButton="false" ExportToPdfText="Export results to PDF" />

<Columns>

<telerik:GridBoundColumn Visible="False" DataField="SessionID" HeaderText="SID" UniqueName="SessionID" AllowFiltering="false" AllowSorting="false" >

<HeaderStyle BackColor="#E3E9DC"></HeaderStyle>

</telerik:GridBoundColumn>

<telerik:GridBoundColumn Visible="False" DataField="Company" HeaderText="Company" UniqueName="Company" AllowFiltering="false" AllowSorting="false" >

<HeaderStyle BackColor="#E3E9DC"></HeaderStyle>

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Ship List" AllowFiltering="false" UniqueName="ShipList" >

<HeaderStyle BackColor="#F2EDB7"></HeaderStyle>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

when the user selects a value in the list the following is called

Protected Sub ddlCompany_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs) Handles ddlCompany.SelectedIndexChanged

Dim ddl As RadComboBox = CType(sender, RadComboBox)

ddl.Items.FindItemByValue(e.Value).Selected = True

CompanyID = CInt(e.Value)

Dim filterExpression As String

filterExpression = "([Company]='" + e.Value + "')"

productionSearchResults.MasterTableView.FilterExpression = filterExpression

productionSearchResults.Rebind()

End Sub

this should go away and call the need data source function (which it does) then rebind the grid with the filtered data set. But when it gets to the rebinding, I'm not seeing any data items, just filter items.... I can clearly see that there is data there, it just doesn't bind.

here's the need data source function

Private Sub productionSearchResults_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles productionSearchResults.NeedDataSource

pageIndex = productionSearchResults.CurrentPageIndex

Controller.Page(Me)

productionSearchResults.DataSource = Productions

productionSearchResults.MasterTableView.VirtualItemCount = totalCount

productionSearchResults.VirtualItemCount = totalCount

End Sub

and my item databound

Protected Sub productionSearchResults_ItemDataBound(sender As Object, e As GridItemEventArgs)

Dim sImgX As String

Dim sImgCheck As String

sImgX = ResolveUrl("~/images/x.gif")

sImgCheck = ResolveUrl("~/images/check.gif")

If TypeOf e.Item Is GridDataItem Then

Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)

If dataItem("ProductionNotes").Text.Contains("NEEDS REVIEW") Then

e.Item.BackColor = Color.Pink

End If

dataItem("SessionID").Text = String.Format("<a href=""{0}"">{1}</a>", _

BuildPageUrl("production/ProductionList.aspx", NavLevel.Session, Integer.Parse(dataItem("SessionID").Text)), dataItem("SessionID").Text)

If Len(PMSession.SID) = 0 Then

dataItem("shipList").Text = String.Format("<a href=""{0}?ProductionID={1}"" target=_Blank><img src=""{2}"" border=0></a>", _

BuildPageUrl("reports/Session/SessionShipList.aspx", NavLevel.Session, iSID), ProductionID _

, ResolveUrl("~/images/report2.gif"))

Else

dataItem("ProductionID").Text = String.Format("<a href=""{0}?id={1}&cmd=2"">{2}</a>", BuildPageUrl("production/ProductionDetail.aspx"), dataItem("ProductionID"), iSID)

dataItem("shipList").Text = String.Format("<a href=""{0}?ProductionID={1}"" target=_Blank><img src=""{2}"" border=0></a>", _

BuildPageUrl("reports/Session/SessionShipList.aspx"), ProductionID, ResolveUrl("~/images/report2.gif"))

End If

Else

End If

any ideas?

[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()

[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)

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!
