Show insert item form automatically when grid is loaded

Hello,

I've got a grid with a custom EditForm in place for inserting records (update and delete are not allowed). Rather than requiring the user to press the Add New Row button, I'd prefer to just have the edit form displaying by default when the screen loads. They should be able to type in the form, commit it, and it will refresh itself with the new data and once again show another new item form.

I assumed there would be a C# command that I could call in Page_Load that would show this form but I was not able to find it. I would highly prefer to do this in C# rather than calling the client-side API with Javascript.

I did begin to create a separate form outside of the grid, but because of my layout it really makes more sense for the insert form to be inside the grid control itself.

Thanks in advance to anyone who can tell me how to do this!

Self-referencing hierarchy dynamicaly

I am trying to look for an example in VB on how to create a Self-referencing hierarchy grid dynamicaly. I have created one where i declare all the columns and parameters. However I want to create it entirly dynamicaly. I am already creating a standard grid in this manner, however I wish to add this option into the user control created.

I included some code, however would like to see an example if possible.

' the nestedDatasource is a dataset with a relation added

If NestedTable Then

RadGrid1.EnableLinqExpressions = False

RadGrid1.ClientSettings.AllowExpandCollapse = True

RadGrid1.MasterTableView.HierarchyDefaultExpanded = False

RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind

RadGrid1.MasterTableView.SelfHierarchySettings.KeyName = NestedTableKey

RadGrid1.MasterTableView.SelfHierarchySettings.ParentKeyName = NestedTableParentKey

' RadGrid1.MasterTableView.SelfHierarchySettings.MaximumDepth = 0

Dim expandCollapseColumn As New GridExpandColumn

expandCollapseColumn.HeaderStyle.Width = 20

RadGrid1.MasterTableView.Columns.Add(expandCollapseColumn)

RadGrid1.MasterTableView.ShowHeader = False

RadGrid1.MasterTableView.HierarchyDefaultExpanded = False

Datasource = NestedDatasource.Tables(0)

End If

....

'create the columns dynamicaly from the dataset

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.Replace("_", " ").ToLower()

If colDataType = "int32" Then

boundColumn.DataFormatString = "<nobr>{0:N0}</nobr>"

boundColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center

.....

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

If NestedTable Then

RadGrid1.MasterTableView.VirtualItemCount = NestedDatasource.Tables(0).Rows.Count()

RadGrid1.DataSource = NestedDatasource

RadGrid1.Visible = True

Else

If Not Datasource Is Nothing Then

RadGrid1.MasterTableView.VirtualItemCount = Datasource.Rows.Count()

RadGrid1.DataSource = Datasource

RadGrid1.Visible = True

Else

RadGrid1.Visible = False

Exit Sub

End If

End Sub

Just a snippet, the issue I have with this is that when I click on the arrow, nothing expands. Not sure where I am going wrong here. Like I said I can get it working when not creating it dynamicaly. Also like to add, I am plugging this into a usercontrol that already creates a normal grid dynamicaly.

Just wondering If I need to do something extra?

Client side removeHandler error

Hello,

I have own composite control inherited from RadWebControl. It contains RadTextBox control where I need handle keyup client event.
I have implemented client class for it and I attached event in initialize function. In dispose function I'm removing this event handler but it causes javascript error:

Line: 6

Error: '_events' is null or not an object

Here is the script:

nData.KnowledgeManagement.Web.UI.Searcher.prototype =

{

initialize: function () {

nData.KnowledgeManagement.Web.UI.Searcher.callBaseMethod(this, 'initialize');

// SearchTextBox

this._searchTextBox = $find(this.get_id() + '_searchTextBox');

this._keyUpDelegate = Function.createDelegate(this, this._keyUp);

$addHandler(this._searchTextBox._textBoxElement, "keyup", this._keyUpDelegate);

// XmlHttpPanel

this._xmlHttpPanel = $find(this.get_id() + '_xmlHttpPanel');

this._xmlHttpPanel._searcher = this;

this._xmlHttpPanel.add_responseEnding(this._xmlHttpPanelResponseEnding);

this._xmlHttpPanel.add_responseError(this._clientResponseError);

},

dispose: function () {

nData.KnowledgeManagement.Web.UI.Searcher.callBaseMethod(this, 'dispose');

if (this._keyUpDelegate) {

$removeHandler(this._searchTextBox._textBoxElement, "keyup", this._keyUpDelegate);

this._keyUpDelegate = null;

}

this._xmlHttpPanel.remove_responseEnding(this._xmlHttpPanelResponseEnding);

this._xmlHttpPanel.remove_responseError(this._clientResponseError);

},

_keyUp: function () {

this._search(this._searchTextBox._textBoxElement.value);

},

...

}

Cound you tell me what I have wrong?

Collapse treeview nodes except active node

Hi in my application i have a treeview control ...
In the pageload i have initialized to collapse all the nodes
The problem is when all the nodes get expanded i am unable to accomodate the list on the page and it gets scrolled...
I need to keep the active selected node displayed with all the other parent nodes collapsed and if i select the other node the previous active node should get collapsed, so that only one node will be active and the rest will be in collapsed state. I hope you got my scenario and will provide a solution for it.

Radeditor Lite on WSS cursur jumps to start of text

We have a problem with the telerik radeditor on WSS v3. We are using the lite editor: 4.5.6

When clicking bold, italic, underline, justify, indent etc. tool buttons in the middle or at the end of some text the cursor jumps to the start of the text(box). When you select some text first the buttons work fine. Also when inserting a table somewhere in the middle of a text it always inserts the table at the start of the text.
Shortcuts like CTRL+B work fine when typing. Toolbuttons like Imagemanager or bullets and numbering work fine as well.

Any help would be much appreciated!

ReorderTabsOnSelect has no effect?

Hi

I am adding tabs to a radtabstrip dynamically and the tabs automatically break over multiple rows when they exceed the width of the tabstrip, which is nice. However when I select a tab in the top row it doesn't reorder - which is not so nice. Similar to this question. I have ReorderTabsOnSelect = true, is there something else I have to set?

Markup:

<telerik:RadTabStrip ID="RadTabStrip1" runat="server"

MultiPageID="RadMultiPage1"

SelectedIndex="0"

Skin="Vista"

ReorderTabsOnSelect="true"

Width="550px">

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server"

SelectedIndex="0"

BorderStyle="Solid" BorderColor="Gray" BorderWidth="1px"

OnPageViewCreated="RadMultiPage1_PageViewCreated">

</telerik:RadMultiPage>
