How to Disable RadGrid

Hi,
How do a RadGrid be in View mode or non editable mode?

Scenario:
Based on the user role, RadGrid should be in Disable mode(no Add/Update/Remove functionalities ) or Enable mode. This should happen dynamically.

Thanks,
Chaitanya

RadTreeNode custom attributes gets lost

I am creating RadTreeNode as follows:

protected RadTreeNode BuildOption(Options option, string questionType)

    {

RadTreeNode nodeOption =

new RadTreeNode();

nodeOption.Text = "(" + option.OrderID.ToString() + ") " + option.Name;

nodeOption.Value = option.OptionsID.ToString();

nodeOption.Attributes.Add(SurveyTreeNodeAttributes.SurveyTreeNodeType, ((int)EnumsBL.SurveyTreeNodeType.Option).ToString());

nodeOption.Attributes.Add(SurveyTreeNodeAttributes.QuestionType, questionType);

nodeOption.ImageUrl = "~/images/ConstIcons/icon-question-option.png";

return

nodeOption;

}

I am also loading the tree nodes on demand as follows:
Code Behind:

[WebMethod]

public static RadTreeNodeData[] LoadNodes(RadTreeNodeData node, object context)

{

EnumsBL.SurveyTreeNodeType nodeType = (EnumsBL.SurveyTreeNodeType)Enum.Parse(typeof(EnumsBL.SurveyTreeNodeType), node.Attributes[SurveyTreeNodeAttributes.SurveyTreeNodeType].ToString());

TreeNodeBuilder treeNodeBuilder = QuestionnaireTreeBuilderFactory.GetQuestionnaireTreeBuilder(nodeType);

return treeNodeBuilder.BuildChildNodesData(node.Value);

}

ASCX:

<telerik:RadTreeView ID="radTree"

Skin="Default"

BackColor="White"

BorderStyle="Solid"

BorderColor="#CCCCCC"

BorderWidth="1px"

AllowNodeEditing="true"

Style="cursor: hand;"

Height="250px"

EnableDragAndDrop="false"

OnNodeClick="NodeClick"

SingleExpandPath="true"

runat="server">

<WebServiceSettings Path="../../Constructor/AdaptiveAnswerBuilder.aspx" Method="LoadNodes" />

</telerik:RadTreeView>

I have debugged method "LoadNodes" and checked that RadTreeNodeData object array contains the two attributes added to the node at the top.

However when a node is selected I only get(after debugging) one node custom attributes, not two:

protected void TreeNodeClicked(object sender, RadTreeNodeEventArgs e)

{

RadTreeNode selectedNode = e.Node; //only one of the attributes, assigned during node creation, are present

switch ((EnumsBL.SurveyTreeNodeType)Enum.Parse(typeof(EnumsBL.SurveyTreeNodeType), selectedNode.Attributes[SurveyTreeNodeAttributes.SurveyTreeNodeType]))

{

case EnumsBL.SurveyTreeNodeType.Option:

SetViewstateVariables(selectedNode);

SetConditionValueHolder(int.Parse(selectedNode.Value));

EnableSaveButton();

break;

default:

pnlCondEqual.Visible = false;

DisableSaveButton();

break;

}

How do I get the other attribute?

Regards,
--Fahmi

[Solved] Issue getting RadGrid-MasterTableView instance on client-side

Hi,

I am having an issue getting the RadGrid-MasterTableView on client-side. I have a RadGrid on the page which does not have static defined columns and I cannot get the mastertableview. Also I defined some static columns and still cannot get the MasterTableVIew.

My final goal is add columns to my RadGrid on the fly using client-side. I could defined to static columns there but other columns are going to be added on dynamically.

What I am missing in my code that I cannot get the MasterTable to add my data to the grid
Thank you in advance

This the code that I am using to get those intance and I can get the grid object but not the MasterTable
var grid = $find("<%=RadGrid1.ClientID %>");
var MasterTable = grid.get_masterTableView();

// var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

<telerik:RadGrid ID="RadGrid1" runat="server" autogeneratecolumns="false" allowsorting="true" allowpaging="true">
<PagerStyle AlwaysVisible="true" />
<MasterTableView>
<Columns>
<telerik:GridBoundColumn DataField="automobile" UniqueName="automobile" HeaderText="automobile" ></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="betrayal" UniqueName="betrayal" HeaderText="betrayal" ></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="DataSourceRecordID" UniqueName="DataSourceRecordID" HeaderText="DataSourceRecordID" ></telerik:GridBoundColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>

Drill down selectively

Hi,

Would it be possible to implement selective drill down on RadChart? Say, only certain chart items have sub-data behind it, while others don't. I would like to "disable" the click event for those that don't. Is this possible?

Thanks.

Getting data from dynamically added control inside RadTreeView

Hi
I have a dynamically added UserControl inside my RadTreeView. During a serverside event, I need to get the control to extract the data inside, but I cannot seem to find the control. The binding is executed both on post and postback.

This is the binding of the control:

foreach (Event item in eventList)

{

RadTreeNode rootNode = new RadTreeNode(item.Name, item.Id.ToString());

rootNode.Expanded = true;

RadTreeNode childNode = new RadTreeNode();

ActorNode actorNode = (ActorNode)LoadControl("ComponentControls/ActorNode.ascx");

actorNode.ID = ACTOR_NODE_ID + item.Id;

List<Actor> actorList = Actor.GetActorList(item.Id);

List<MunicipalityActor> munActorList = MunicipalityActor.GetMunActorList(MunCode);

actorNode.InitializeControl(municipalityActorList, actorList);

childNode.Controls.Add(actorNode);

rootNode.Nodes.Add(childNode);

RadTreeView_Actors.Nodes.Add(rootNode);

}

This is the serverside event, where I am trying to get hold of the data...

foreach (RadTreeNode rootNode in RadTreeView_Actors.Nodes)

{

Control control = rootNode.Nodes[0].FindControl(ACTOR_NODE_ID + rootNode.Value);

}

Is the control-id not what i set it to?
