Filter does not work on GridBoundColumn(DateTime Type) if non-datetime text entered into column filter box.

I am having a RadGrid on my page.

This grid is having a GridBoundColumn of type "DateTime" with the CurrentFilterFunction="EqualTo" with in-place filter for the columns. My requirement is not to use the DatePicker icon to select date rather allow user to write text directly into filter through the column. But while trying with the filter functionality typing any non-datetime text into the column filter control and clicking enter postbacks the page but it does not filters, the same data remains there in the page, whereas it should filter and should show no data for any non-datetime entry into filter control.

Here is my RadGridBound column's source:-

<telerik:GridBoundColumn UniqueName="DOB" DataField="DOB" HeaderText="DOB"

CurrentFilterFunction="EqualTo" ShowFilterIcon="False" AutoPostBackOnFilter="True"

DataFormatString="{0:d}" DataType="System.DateTime">

<ItemStyle HorizontalAlign="Right" />

<HeaderStyle HorizontalAlign="Right" Width="100px" />

<FooterStyle HorizontalAlign="Right" />

</telerik:GridBoundColumn>

Can anybody have any idea for solving this issue.
Thanks in advance.

Handling events fired from dynamically created NodeTemplate

Hi,

I am adding Node Templates like;

protected void RadTreeView2_TemplateNeeded(object sender, RadTreeNodeEventArgs e)

{

bool someCondition = true;

if (someCondition)

e.Node.NodeTemplate = new BoxTemplate();

else

e.Node.NodeTemplate = new OtherTemplate();

}

And here is my BoxTemplate class;

class BoxTemplate : ITemplate

{

public void InstantiateIn(Control container)

{

Label nodeLabel = new Label();

nodeLabel.ID = "NodeLabel";

nodeLabel.DataBinding += new EventHandler(NodeLabel_DataBinding);

container.Controls.Add(nodeLabel);

ImageButton delButton = new ImageButton();

delButton.ImageUrl = "~/images/icons/delete16.png";

delButton.OnClientClick = "return ConfirmDelete();";

container.Controls.Add(delButton);

}

private void NodeLabel_DataBinding(object sender, EventArgs e)

{

Label theLabel= (Label)sender;

RadTreeNode node = (RadTreeNode)theLabel.BindingContainer;

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

}

I couldn't figure it out how to add server side click event to my delButton and handle it at code behind.
Any help would be appreciated. TIA.

Persistence of configuration after postback

Dear all

I wonder if somebody could help clarify something about the persistence behaviour I should be expecting from the RadTreeView's EnableViewState property? I am not sure if I am seeing the behaviour by design or not ...

I have a RadTreeView control which does not appear to maintain its node display arrangement after a postback, in that if the user expands a node, after postback the node has been collapsed once more. Also, when it comes to the underlying datasource bindings etc of the RadTreeView control, it seems as though the control does not persist the Datasource property, for example, that is configured when the control first loads on the initial post of the page. For example, the RadTreeView in question binds to a hierarchical datasource object, but I am having to reconfigure the RadTreeView to a datasource object after each postback, which seems a little counter-intuitive, and a bit of an inefficiency that I would expect the RadTreeView control to avoid by maintaining the state of the datasource object. Perhaps the data configuration and hierarchy display changes would need to be made manually with a Session object instead?

However, I would be interested to know if this is the correct way to go about this issue, or whether I am missing something of importance.

Thanks very much for any advise!

Regards

RadGrid issue: after postback, contents of datetime column are being cleared onFocus

Hello,

There is a very similar problem with <GridDateTimeColumn>, as this message: http://www.telerik.com/community/forums/reply-thread.aspx?messageId=2088875&threadId=530174 .

However, this problem still happens after the Telerik.Web.UI_2012_1_424_Dev release build.

My problem:

I have a grid with EditForm edit mode enabled.

When I select an editable field that fires a OnTextChanged post back event, if I give focus to an editable <GridDateTimeColumn> field, I get a problem.

Prior to this hotfix, I would get an error the same error: "Text property cannot be set. String was not recognized as a valid DateTime."

After this hotfix, what happend is when I focus an editable <GridDateTimeColumn> field, the contents of the field disappear. Actually, the contents appear to first be selected, then they disappear. Focusing on other types of columns does not do this.

Normal behavior (and expected), as when tabbing from field to field without this post back event, the items are selected. But the selection is not removed.

Here are the two date/time column definitions in my grid, demonstrating the problem:

<telerik:GridDateTimeColumn DataField="ValidFromDate"

FilterControlAltText="Filter ValidFromDate column" HeaderText="Valid From"

UniqueName="ValidFromDate" DataFormatString="{0:MM/dd/yyyy}"

MinDate="1901-01-01" MaxDate="9999-12-31 23:59:59.999999">

</telerik:GridDateTimeColumn>

<telerik:GridDateTimeColumn DataField="ValidToDate"

FilterControlAltText="Filter ValidToDate column" HeaderText="Valid To"

UniqueName="ValidToDate" DataFormatString="{0:MM/dd/yyyy}"

MinDate="1901-01-01" MaxDate="9999-12-31 23:59:59.999999">

</telerik:GridDateTimeColumn>

Here is the column that fires the OnTextChanged event while in Edit-Mode (see <EditItemTemplate>):

<telerik:GridTemplateColumn HeaderText="Override Discount $" UniqueName="OverrideDiscount">

<ItemTemplate>

<telerik:RadNumericTextBox NumberFormat-DecimalDigits="2"

ID="txtOverrideDiscountDsp" runat="server"

gmNumberFormat-AllowRounding="False" Type="Currency" Width="52px"

BackColor="Transparent" BorderStyle="None"

Value='<%#CoalesceNumericValuesToRadNumberControl(DataBinder.Eval(Container.DataItem, "UpdateCustomerPrice"), null) %>'>

</telerik:RadNumericTextBox>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadNumericTextBox NumberFormat-DecimalDigits="2" ID="txtOverrideDiscount" runat="server"

AutoPostBack="true" OnTextChanged="txtOverrideDiscount_OnTextChanged"

gmNumberFormat-AllowRounding="False" Type="Currency"

Value='<%#CoalesceNumericValuesToRadNumberControl(DataBinder.Eval(Container.DataItem, "CustomerPrice"), null) %>'>

</telerik:RadNumericTextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Thanks

Radgrid: show/hide command item using IsitemInserted

Hello,

It's urgent.
Am using vb.net 2010.
I have master table view and detail table view with command items at top.
In master table view i can hide link button using
1. for Add new link button: Visible='<%# Not rgView1.MasterTableView.IsItemInserted %>'
2. for Cancel button: Visible='<%# rgView1.EditIndexes.Count > 0 Or rgView1.MasterTableView.IsItemInserted %>
How to achieve the above two in detail table?
I tried using Visible='<%# Not(Container AS GridItem).OwnerTableView.IsItemInserted %>'
But it throws error as Operator Not is not defined for type GridItem.

Please guide me
Thank you
Jayanthi
