Hi everyone,

I would like to know why the grid takes at least 3 times longer to load in IE compared to Chrome and Firefox.

Is there an explanation to that?

Thanks a lot,

Grouping not being displayed on Header for Sub Groups

I'm having an issue where the grid is not displaying the Ship sub total (see attachment).

How can I get the Ship Total to display the total for the Ship instead of the "{0:C}" literal?

How can I also get rid of the SORT bar (see attachement). I don't have any code behind to handle this and I don't need to.

Here is some pertinent code that I have the way the grid is set up....

<telerik:RadGrid ID="RadGrid1" runat="server"

PageSize="20" AllowSorting="True" AllowPaging="True" ShowGroupPanel="True"

OnColumnCreated="RadGrid1_ColumnCreated">

<PagerStyle Mode="NumericPages"></PagerStyle>

<MasterTableView Width="100%">

</MasterTableView>

<ClientSettings>

<Resizing AllowColumnResize="True"></Resizing>

</ClientSettings>

</telerik:RadGrid>

protected void Button1_Click(object sender, EventArgs e)

{

string groupBY = "CruiseLine [CruiseLine], Sum(Sales) GroupTotal [CruiseLine Total] Group By CruiseLine";

group(groupBY);

}

protected void Button2_Click(object sender, EventArgs e)

{

string groupBY = "Ship [Ship], Sum(Sales) GroupTotal [Ship Total] Group By Ship";

group(groupBY);

}

protected void Button3_Click(object sender, EventArgs e)

{

string groupBY = "Date [Date], Sum(Sales) GroupTotal [Date Total] Group By Date";

group(groupBY);

}

protected void group(string groupBY)

{

try

{

GridGroupByExpression expression1 = GridGroupByExpression.Parse(groupBY);

this.CustomizeExpression(expression1);

this.RadGrid1.MasterTableView.GroupByExpressions.Add(expression1);

}

catch (Exception ex)

{

lblError.Text = string.Format("<span style='color:red'>Cannot add group by expression: {0}</span>", ex.Message);

lblError.Visible = true;

}

finally

{

BindData();

}

protected void BindData()

{

Hashtable htParams = new Hashtable();

htParams.Add("@CruiseLine", ViewState["prmCruiseLine"]);

htParams.Add("@Ship", ViewState["prmShip"]);

htParams.Add("@FromDate", FromDate.SelectedDate.Value.ToShortDateString());

htParams.Add("@ToDate", ToDate.SelectedDate.Value.ToShortDateString());

// Call SPROC to populate grid

DataUtiliities data = new DataUtiliities("PrepaidConnectionString");

DataSet dsRpt = data.ExecuteDataSet("SelectProductInfoByShipAndDate2", htParams);

// Bind the Grid

RadGrid1.DataSource = dsRpt.Tables[0].DefaultView;

RadGrid1.DataBind();

}

Here is the output of the groups during debugging:

groupBY = "CruiseLine [CruiseLine], Sum(Sales) GroupTotal [CruiseLine Total] Group By CruiseLine"

expression1 = {CruiseLine , sum(Sales) GroupTotal Group By CruiseLine}

groupBY = "Ship [Ship], Sum(Sales) GroupTotal [Ship Total] Group By Ship"

expression1 = {Ship , sum(Sales) GroupTotal Group By Ship}

[Solved] Hierarchy access

Hi everyone,

In this other question of mine, I am facing a different problem than the previous one.

I currently have a grid, inside a radtabstrip inside a grid. In order to makes this easier, here is the name of the items.

Parent grid : grdChauffeurs
Tabstrip : RadTabStrip2
Inner grid : grdOrdre

Here is what I would like to achieve.

When I drop a row in grdDriver, I want the row to be added in the grid grdOrdre.

In my rowdrop event I have the following code :

Protected Sub grdListeCommande_RowDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridDragDropEventArgs) Handles grdListeCommande.RowDrop

Dim RowDragged As GridDataItem

Dim RowIndexDestin As Integer

Dim intChfNRI As Integer

Dim intAtcNRI As Integer

Dim tabstrip As RadTabStrip

Dim grille As RadGrid = Nothing

For Each item As GridNestedViewItem In grdChauffeurs.MasterTableView.GetItems(GridItemType.NestedView)

tabstrip = item.FindControl("RadTabStrip2")

grille = tabstrip.MultiPage.FindControl("grdOrdre")

Next

RowDragged = e.DraggedItems.FirstOrDefault()

If (e.DestDataItem IsNot Nothing) Then

If (e.DestDataItem.OwnerGridID = grdChauffeurs.ClientID) Then

Me.RowIndex = e.DestDataItem.ItemIndex

intAtcNRI = CInt(RowDragged("ATCNRI").Text)

intChfNRI = Me.DataTableChauffeur.Rows(Me.RowIndex).Item("NRI")

End If

Select Case False

Case intChfNRI <> Nothing

Case intAtcNRI <> Nothing

Case pfblnGetRoadSheet(intChfNRI, intAtcNRI)

Case Else

e.DestDataItem.Expanded = False

e.DestDataItem.Expanded = True

grille.DataSource = Me.DataTableMouvement

End Select

End If

End Sub

I am a new developper and I'm a bit confused with how all the hierarchy works in the radgrid.

Thank you in advance for you most appreciated help

Problem Inserting Resource Type values into DB

Hi I am new-ish to teleriks tools so I will try my best to describe the problem I am having.

I am using telerik radscheduler that uses SQL datasource objects for its datasource. I want to be able to add a dropdown list of generic commands that the user can select from and subsequently save. I have added a resourcetype as follows:

<telerik:ResourceType ForeignKeyField="id"

KeyField="id" Name="Commands" TextField="CommandName" />

</ResourceTypes>

Per one of your demos I am using the Form Created Event to fill the dropdown with the list of commands. Like this:

protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)

{

if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))

{

RadComboBox ddlCommands = (RadComboBox)e.Container.FindControl("ResCommands");

if (ddlCommands != null)

{

int assetID = int.Parse(Request.QueryString["id"]);

string portal = (string)Session["Portal"];

AssetFactory assetFactory = new AssetFactory(portal);

ddlCommands.DataSource = CommandEnums.GetListItems(assetFactory.GetAssetType(assetID));

ddlCommands.DataTextField = "Text";

ddlCommands.DataValueField = "Value";

ddlCommands.DataBind();

}

When I click the save button I get this error: Invalid length for a Base-64 char array.

Thread information:

Thread ID: 12

...

Is impersonating: False

I did attempt to use a custom attribute to try this as suggested in another thread, but was unable to get the RadComboBox successfully created dynamically.

Any help would be greatly appreciated.

Thanks,
Justin

[Solved] Telerik RadControl Grid: Scroll bug in IE & Chrome

Hello,

Im using the Grid control from Telerik's RadControls. The grid is populated with thousands of records and lists 50 records per page. I have some filtering options appearing above and the solution is in ASP.NET 3.5 with NHibernate 2.1.

Everything works fine and dandy except for when i select one of the bottom rows and some weird onfocus-event occurrs. When a search/listing has been occurred and the focus is on, lets say the search button. I then select one of the bottom rows between record 40-50, and the browser immediately scrolls down an inch or two. But when the focus is on one of the rows within the grid table, i no longer have these strange scrollings. But if i just switch the focus on anything outside the grid, the scrolling bug appears again.

This appears in IE and Chrome, but not Firefox. I guess its some onfocus event that fires when putting the radgrid in focus, but i cant find any solution on how to fix it.

Please help me, its very annoying!

Best regards, Mattias

Problem reading values from custom treenode template's controls (works for subtrees but not for root tree)

Hello,

I use a RadTree with custom format of its elements. Namely, each element has also 3 radio buttons as RadioButtonList, defined in a custom template. The code used to create items of new radTree is:

RadTreeNode node = new RadTreeNode(usedName + " [" + rs.ToString() + "]", "SECTION_" + rs.ToString()); // just some name and value

node.NodeTemplate = new AdminFunctionsPhenoTreeTemplate(); // makes buttons

node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

PhenoTree.Nodes.Add(node); // adding node to RadTree.

// selections.

RadioButtonList rbRights = (RadioButtonList)node.FindControl("rbRights");

if (rbRights != null)

{

setAccessLevelToRB(rbRights, accessLevel);

// set correct radio button using rbRights.SelectedIndex

}

node.DataBind();

This code successfully creates desired nodes and setAccessLeveltToRB indeed sets desired radio button as instructed.

The very same code used to create sub-trees in server side callback - I use dynamic creation of subtrees after user wants to expand the tree. The only formal difference, it attaches new subtree to Nodes property of a parent node (as opposed to RadTree "PhenoTree" object here, of course).

When I receive a postback, I read the values of radio buttons like this:

List<RadTreeNode> alls = (List<RadTreeNode>)PhenoTree.GetAllNodes();

foreach (RadTreeNode node in alls)

{

RadioButtonList rbRights = (RadioButtonList)node.FindControl("rbRights");

accessLevel = getAccessLevelFromRB(rbRights); // this routine simply examines rbRights.SelectedIndex

}

But buttons of primary root tree, created by the snippet above, always return default value, neither the one I inserted either in creation code (albeit it was reflected on screen) nor that I selected by mouse.

Template:

class AdminFunctionsPhenoTreeTemplate : ITemplate

{

public void InstantiateIn(Control container)

{

container.Controls.Add(new LiteralControl("<table style=\"margin:0px;padding:0px;\"><tr><td>"));

Label label1 = new Label();

label1.ID = "ItemLabel";

label1.Text = "Text";

label1.Font.Size = 8;

// label1.Font.Bold = true;

label1.DataBinding += new EventHandler(label1_DataBinding);

container.Controls.Add(label1);

container.Controls.Add(new LiteralControl("</td><td>"));

RadioButtonList rbRights = new RadioButtonList();

rbRights.ID = "rbRights";

rbRights.Items.Add(new ListItem("r/o"));

rbRights.Items.Add(new ListItem("r/w"));

rbRights.Items.Add(new ListItem("r/w/meta"));

rbRights.SelectedIndex = 0;

rbRights.RepeatDirection = RepeatDirection.Horizontal;

container.Controls.Add(rbRights);

container.Controls.Add(new LiteralControl("</td></tr></table>"));

}

private void label1_DataBinding(object sender, EventArgs e)

{

Label target = (Label)sender;

RadTreeNode node = (RadTreeNode)target.BindingContainer;

string nodeText = (string)DataBinder.Eval(node, "Text");

target.Text = nodeText;

}

I wonder what I am missing, please help me to make this work!

Update EditForm TextBox at Client side

Hello,

I'm using Dynamic Edit Form Template for editing in RadGrid. I have a custom control created to Combine a RadTextBox and a Button.
This control populated on Edit Form when I click on edit/insert button. When I click on button a pop-up window opens through Javascript code. From the Popup window I select one record and click on save and Close button of popup window. The string which is returned from the popup window is stored back in the TextBox control using AjaxPostback method. But doing this I lost my other controls selected values.

Ex. I have three controls on my edit/insert form. When we insert new record Two dropdowns and one my custom control [textbox with button] is populated. I select values in two dropdowns and then click on popup button. When the value is stored back in my textbox from popup window I lost my selection in two dropdowns. I'm not getting how to keep those values selected in my dropdowns.

To resolve the this issue I thaught to update my textbox at client side so that ajaxpostback will not occur and I do not lost my selected values from the dropdowns and other controls. But I can not access my Textbox of edit form through javascript. I tried to use

var editedItemsArray = grid.get_editItems();

But i dont know how to access my TextBox1 from this editeditemsArray.

Please advise.

[Solved] Car Rental

hello,

I downloaded the source code of the example "carrental" and I can not build the project.

The error message presented to me is: "Could not load file or assembly'Telerik.OpenAccess, 2010.2.714.1 Version =, Culture = neutral, PublicKeyToken =7ce17eeaf1d59342' or one of ITS dependencies."

I already tried to do the "Upgrade References" in menu "Telerik" in VS2010, but instead of this error is to appear the following error" Could not load file or assembly'Telerik.Web.UI' or one of ITS dependencies. " repeated five times.

Is there any place where you can download the version of ORM Q2 2010? Or your demoversion will be available in Q3 2010?

Greetings
bruno.
