Exclude control from ajaxifying

I am unable to exclude ajax enabled control (Button2) that resides inside panel (PanelButtons) as shown below. I tried to use the following code, I don't get any errors, but the button click is not working. I tried by using RadScriptManager's RegisterPostBackControl method. I also tried to disable AJAX via the OnRequestStart event as well as InitializeRequest event. None of them seems to work. So, is there any better solution for this scenario? Thanks.

<asp:Content runat="server" ContentPlaceHolderID="Content1">
   <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

Adding more than one relationship to RadGrid in code

Hello,

I have a hiearchal radgrid with a parent level that has 2 key columns.

For example:

ID, Sequence, first_name, last_name

This can result in data that looks like the following:

1, 1, John, Doe
1, 2, Adrian, Shepard
2, 1, Mary, Jane

That child level has:

ID, Sequence, Data

So you can have data that looks like the following:

1, 1, 0.256
1, 2, 0.944
2, 1, 0.109

How can I code the grid so that the child level uses both ID and Sequence as a composite key when the radgrid is built entirely in code?

At the moment I use:

relationFields = New GridRelationFields()

relationFields.MasterKeyField = "ID"

relationFields.DetailKeyField = "ID"

tableView.ParentTableRelation.Add(relationFields)

How do I code it so that it references both ID and Sequence as the relationship so that the grid looks like:

John, Doe
     0.256
Adrian, Shepard
     0.944
Mary, Jane
    0.109

instead of:

John, Doe
     0.256
    0.944
Adrian, Shepard
     0.256
    0.944
Mary, Jane
    0.109

which is wrong, since it is repeating the values on 2 rows because they share the first part of the relationship instead of also considering the second column.

I've looked in the documentation but the only information I've found on creating a composite key relationship involved doing so in the HTML, which is not an option for me as the radgrid is 100% generated in VB code on the server side.

Thanks for any assistance.

RadDropDownTree custom filtering

Hello,

I'm trying to write a custom filtering for the RadDropDownTree however i'm faced some performance issues. Here is my JS code :

function OnHierarchicalClientLoad_<%= ClientID %>(sender, eventArgs) {

var dropDownTree = $find("<%= RadDropDownTree.ClientID %>");

var typingTimer; //timer identifier

var doneTypingInterval = 1000; //time in ms, 5 second for example

$input = $("<input type=\"search\" class=\"search-field\" name=\"the_search\">");

$input.on('keyup', function () {

clearTimeout(typingTimer);

typingTimer = setTimeout(function () {

$value = $input.val();

var tree = dropDownTree.get_embeddedTree();

tree.trackChanges();

var nodes = tree.get_nodes();

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

var node = nodes.getNode(i);

SetHierarchicalComboBoxItemVisibility(node, $value);

}

tree.commitChanges();

}, doneTypingInterval);

});

$input.on('keydown', function () {

clearTimeout(typingTimer);

});

$("#<%= RadDropDownTree.ClientID %> .rddtHeader").append($input);

}

function SetHierarchicalComboBoxItemVisibility(node, filter) {

var isVisible = false;

var allNodes = node.get_allNodes();

for (var i = 0; i < allNodes.length; i++) {

var childNode = allNodes[i];

isVisible = SetHierarchicalComboBoxItemVisibility(childNode, filter);

}

isVisible = (isVisible || filter == "" || node.get_text().toLowerCase().indexOf(filter.toLowerCase()) != -1);

node.get_element().style.display = isVisible ? "" : "none"; //Workaround

//node.set_visible(isVisible); //performance too slow

return isVisible;

}

As you can see I used a workaround because the set_visible() function is too slow when there is a bit amount of nodes (some thousands). It seems that it use some functions that do some css stuffs on sibling node as ensureAppearance().

So I have two questions :

- Is there a way to optimise the use of set_visible() function on a huge amount of nodes ?

- Else, is my workaround may cause problems?

Thank you,

DropDownTree

Drop down filter in template column

Hi,

I have created a template column and bound it to a RadGrid.

However, I would like to implement drop down filtering on the column as you describe here:

http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx

Can you clarify if this is possible to achieve using a grid template column?

I raised a support ticket about this back in Feb 2016 and got the following response:

Hello Richard,

Thank you for contacting us.

You can add a RadComboBox control as a filter item of the TemplateColumn the same way as you did with a BoundColumn. Generally you need to implement a FilterItemTemplate and use pretty much the same approach as the one from the demo.

I hope this information helps.

Regards,
Kostadin
Telerik

I have tried this approach and I get problems. Could you please show me an example or post some code here?

Here is the definition of my Template column:

GridTemplateColumn templateColumn = new GridTemplateColumn();
templateColumn.ItemTemplate = new GenericGridLinkedItemTemplateColumn(columnName, displayName, listName, lookupType, ActiveColumnName, ItemActiveValue, popoverUrl, itemType, headerText.Replace(" ", string.Empty), genericGridUrl, tab);
templateColumn.UniqueName = columnName;
templateColumn.HeaderText = headerText;
templateColumn.AllowFiltering = true;
templateColumn.CurrentFilterFunction = GridKnownFunction.Contains;
templateColumn.AutoPostBackOnFilter = true;
templateColumn.ShowFilterIcon = false;
templateColumn.DataField = columnName;

At the moment it renders a text box to filter by, I would like to change it to a dropdown list.
