How to rebind a grouping RadGrid without collapsing the items

Hi,

In my current project I have a RadGrid with multilevel grouping of items.

The items displayed on the RadGrid are stored in a DataSet.

When any of items in the DataSet changes (because of some operations on the web page), I redisplay the RadGrid as follows:

this.RadGrid.DataSource = DataSet;
this.RadGrid.DataBind();

However, this causes all the RadGrid items to be collapsed (if any of them has been expanded).

Can you please show me how to redisplay the updated DataSet on the RadGrid and at the same time preserving the expanded items?

Please note that all operations need to be done on the server (instead of client)?

Regards,
Herman

SubObjects (MetaFields + MetaKey) not displayed on client-binding

Hi there,

I really like the telerik ajax tools, but I have a slight problem now: the property value of a subobject is not displayed in the grid: Status.Shortcut. Pasting the json code (extracted by fiddler2) into a json viewser, looks ok.

Telerik-Version: v.2010.2.929.35

Even when creating a client side array, it doesn't display subobject's values.

Alerting the field says: ok - is there.

WHAT CAN I DO? Please help.

Thank you very much.

Client-Side DataBinding:

function UpdateGrid(rows) {

clearError();

var grid = $find("<%=gridTickets.ClientID %>");

var mtv = grid.get_masterTableView();

alert(rows[0].Status.Shortcut); // <--WORKS GREAT!!!!

mtv.set_dataSource(rows);

mtv.dataBind();

return;

}

Page.aspx:

<telerik:RadGrid ID="gridTickets" runat="server" >

<MasterTableView DataKeyNames="Id">

<Columns>

<telerik:GridBoundColumn DataField="Id" HeaderText="Id" Display="false" />

<telerik:GridBoundColumn DataField="Status.Shortcut" HeaderText="Status" />

<telerik:GridBoundColumn DataField="Subject" HeaderText="Betreff" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

[Solved] Hide GridDataItem - Visible False

I have a very simple Grid that includes a hyperlink column using an image as the link:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="sds_Credentials" GridLines="None" Skin="WebBlue" AllowSorting="True" Width="800px">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="IDCredentials" DataSourceID="sds_Credentials">

<CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

<RowIndicatorColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="CredentialName" HeaderText="Credential"

SortExpression="CredentialName" UniqueName="CredentialName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserLogin" HeaderText="Login"

SortExpression="UserLogin" UniqueName="UserLogin">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserPassword" HeaderText="Password"

SortExpression="UserPassword" UniqueName="UserPassword">

</telerik:GridBoundColumn>

<telerik:GridHyperLinkColumn DataNavigateUrlFields="Website" HeaderText=" "

DataNavigateUrlFormatString="{0}"

UniqueName="Website" AllowFiltering="False" ItemStyle-HorizontalAlign="Center">

<ItemStyle Width="50px" CssClass="radgrid" />

</telerik:GridHyperLinkColumn>

<telerik:GridHyperLinkColumn DataNavigateUrlFields="IDCredentials" HeaderText=" "

DataNavigateUrlFormatString="credentials_details.aspx?IDCredentials={0}"

Text="Details" UniqueName="IDRolodex" AllowFiltering="False" ItemStyle-HorizontalAlign="Center">

<ItemStyle Width="75px" CssClass="tbltdbutton" />

</telerik:GridHyperLinkColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Code behind:

Protected Sub RadGrid1_ItemDataBound1(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim hyplnk As HyperLink = DirectCast(item("Website").Controls(0), HyperLink)

hyplnk.ImageUrl = "../../../images/iconIE.gif"

hyplnk.Target = "_blank"

End If

End Sub

This works great.

However, I would like to hide the image if there is no hyperlink in the data field. Something like:

Protected Sub RadGrid1_ItemDataBound1(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = TryCast(e.Item, GridDataItem)

Dim value As String = item("Website").Text

If value < "1" Then

Dim hLink As HyperLink = DirectCast(item("Website").Controls(0), HyperLink)

hLink.ImageUrl = "../../../images/iconIE.gif"

hLink.Target = "_blank"

hLink.Visible = False

End If

End Sub

This does not work. Any help would be much appreciated.

"RadWindow1";

rwForm.NavigateUrl = "~/FormsViews/EditForm.aspx";

rwForm.VisibleOnPageLoad =

true;

rwForm.Modal =

true;

rwForm.Overlay =

true;

rwForm.Behaviors =

WindowBehaviors.Close;

rwForm.Width = 1000;

rwForm.Height = 650;

}

rwmForm.Windows.Add(rwForm);

}

protected void rcmViewContextMenu_ItemClick(object sender, RadMenuEventArgs e)

{

if (rtsEditEntity.SelectedTab.Value == "5")

{

int _ViewId = Convert.ToInt32(hiddenViewId.Value);

RadWindow rwView = new RadWindow();

RadDatePicker in control issue..

Hi,

I am using a RadDatePicker in a setup that is similar to the ActiveSkill example (i.e. a RadSplitter with two RadPanes), the right most
RadPane is the destination pane for my custom control that is loaded by Page.LoadControl and added by Page.Controls.Add().

Now I noticed that if I create a custom control with only a RadDatePicker in it, the calender popup button does not do anything,
if I move the control to the page with the RadPanes and the RadSplitter (i.e. out of the custom control) it works fine.

What am I missing?

Thanks,
-Carlo
