Hi,

I have a self-referencing grid.  I'm declaring it and configuring it all in the aspx declaration and binding it via the "rebind"-"needs-data" approach.   It works fantastic.

The grid is initialized with a large data set (using the HierarchyLoadMode="ServerOnDemand") mode, and I have some PreRender code that expands the first 2 levels of the hierarchy.

Now the user can filter data, we are not using the grids filter but re-querying the database and returning a new dataset and rebinding to the grid.  If that dataset contains less than 20 records, the user wants all the nodes expanded by default, otherwise only the first 2.

I've tried several approaches: 
1.) Expanding in pre-render.  Doesn't work, only 2 sub-layers have data.
2.) changing HierarchyLoadMode to "ServerBind" and expanding in Pre-Render using a recursive expand function (code listed below)   Seems to work until the 4th sub-level, after the 4th sublevel the item.ChildItem.NestedTableViews.count is 0, even though I know there are 6 levels in the data set.

My next step is to try it with HierarchyLoadMode = "client" and my last ditch effort to dynmically build the grid for every request.  any guidence would be appreciated.



protected void RadGrid1_PreRender(object sender, EventArgs e)
        {

            if (ExpandAll)
            {
                RadGridExpandHierarchy(RadGrid1.Items);

            }
}

        private void RadGridExpandHierarchy(GridDataItemCollection items)
        {
            foreach (GridDataItem item in items)
            {
                if (item.GetDataKeyValue("IsPolicyRow").ToString()=="0" && item.ChildItem != null && item.ChildItem.NestedTableViews != null && item.ChildItem.NestedTableViews.Count() > 0)
                {
                    GridTableView childtableView = (GridTableView)item.ChildItem.NestedTableViews[0];
                    RadGridExpandHierarchy(childtableView.Items);
                }
                if (item.CanExpand && item.GetDataKeyValue("IsPolicyRow").ToString() == "0")
                    item.Expanded = true;

            }

        }

Greetings,

I have an issue with the DateTimePicker in Google Chrome 17.0.963.83 m and Rad AJAX for ASP.NET 2011.1.315.35 and it's that the calendar popup is displaying far from the input field. Check the attached image.

Thanks in advance

I have a custom provider, and in the case where we are creating a new file, I would like to append the current search pattern if the current pattern looks like a file extension and the current file does not have a file extension.  To do this, I need to get the current search pattern from the RadFileExplorer in the code behind.

Hello, I have come across an issue with wiring up a RadGrid to an OpenAccessDataSource in the 2012 Q1 release.

Basically, when I add an OpenAccessDataSource to a RadGrid, the grid will display all the columns returned by the data source (AutoGenerate Columns is on by default) but when I open the Editor, there are a number of problems.

- Initially, with the grid selected in the left hand pane, the right hand pane displays all the properties for the General tab, but if I select Paging, Style, Grouping or Client Settings, no properties at all are display in the right hand pane.
- If I select Master TableView from the left hand pane, all the info displays for the General tab but not for Paging, Styles, Grouping or Columns.
- Any changes i make to the properties displayed in either of the General tabs are NOT saved
- If I switch to Source View in VS 2010 and manually add properties to the code (eg add a DataKeyName), these properties are not displayed in the grid editor

I have tried connecting the same grid to an ObjectDataSource and the grid editor performs normally.

I use OpenAccessDataSources a lot for quickly creating admin pages to administer lookup tables in the database, so this is a real problem for me.

Everything was working fine in the previous release.

Please help!

Jegards,
Jonathan

I have a radeditior on my page with a custom list of characters. I am having problems adding the & symbol to the symbols list. The space in the list where the & should show up appears blank. Please see the attached screenshot. The blank space (which appears gray because it is selected) after the percent sign should be where the & symbol appears. I have tried adding it by
 And by

And receive the same results. Does anyone have any idea why this would happen?

Thanks!

Hi - I'm struggling with something that I can't seem to figure out.  I want to be able to display a RadComboBox that can be used on each row.  I need this because setting up the data I'm using requires a selection be made for each row.  My grid markup is as follows:

 

<telerik:RadGrid ID="grdRules" runat="server" GridLines="None" AutoGenerateColumns="False" OnItemCreated="grdRules_ItemCreated"

HorizontalAlign="NotSet" OnNeedDataSource="grdRules_NeedDataSource" Width="99%" OnPreRender="grdRules_PreRender" PageSize="100">

    <MasterTableView DataKeyNames="ID" GridLines="None" Width="100%" EditMode="InPlace">

        <Columns>

            <telerik:GridCheckBoxColumn UniqueName="IncludeRuleColumn"/>

            <telerik:GridTemplateColumn UniqueName="RuleName" HeaderText="Name" DataField="Name" SortExpression="Name">

                <ItemTemplate>

                    <asp:Label ID="lblName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Name") %>'></asp:Label>

                </ItemTemplate>

            </telerik:GridTemplateColumn>

            <telerik:GridTemplateColumn HeaderText="Message" UniqueName="ValidationMessage" DataField="MessageText" SortExpression="Message.MessageText">

                <ItemTemplate>

                    <telerik:RadComboBox runat="server" ID="cbMessage" OnDataBinding="cbMessages_DataBinding" DataTextField="MessageText" DataValueField="ID"></telerik:RadComboBox>

                </ItemTemplate>

            </telerik:GridTemplateColumn>

            <telerik:GridTemplateColumn HeaderText="Outcome" UniqueName="OutcomeType" SortExpression="OutcomeType">

                <ItemTemplate>

                    <telerik:RadComboBox runat="server" ID="cbOutcomeTypes" OnDataBinding="cbOutcomeTypes_DataBinding"></telerik:RadComboBox>

                </ItemTemplate>

            </telerik:GridTemplateColumn>

        </Columns>

    </MasterTableView>

</telerik:RadGrid>

 

When the grid displays, they all look like the RadComboBox, but they're all disabled and cannot be 'dropped down' to select an item.  I've tried forcing all of the rows into edit mode with EditItemTemplate entries as well, and that doesn't work either.  Here is the server side code I've tried that with:

Is what I'm explaining possible with the RadGrid?  What am I missing here?  I feel like I've tried everything today to get this to work, and to no avail.  Ideas please?  Thanks!

Hallo,

I have a RadComboBox with set "CheckBoxes = true". The header displayes always "X items checked". I want to display an other text. How can I affect the header text?

Thanks

I'm having trouble initializing the spell check on mulitiple mvc editor controls.
I was able to init the speller check on 1 editor control by following the example on
http://www.telerik.com/community/forums/aspnet-mvc/editor/mvc-editor-with-spellcheck.aspx

However, I would like to check all editors.
I'm following the example on:
http://www.telerik.com/help/aspnet-ajax/spell-how-to-mutliple-textareas.html

but I'm not sure how to set the source list with the mvc controls.
i tried:

 

 

var sources =

 

[

new Telerik.Web.UI.Spell.HtmlElementTextSource('PurposeIframe'),

new Telerik.Web.UI.Spell.HtmlElementTextSource('ActivitiesIframe'),

new Telerik.Web.UI.Spell.HtmlElementTextSource('ScopeIframe')

 

];

and also

new Telerik.Web.UI.Spell.HtmlElementTextSource($('#PurposeIframe')),

 

 

 When i call

var

 

 

spell = GetRadSpell('ctl00_ctl00_MainContent_spell1');

 

spell.set_textSource(

 

new MultipleTextSource(sources));

 

spell.startSpellCheck();

 

 

 

i keep getting : No value or innerHTML attribute. Cannot access text.

Thanks in advance,
Michael

Hello telerik,

I use his code on IIS 7


in a aspx file under a folder with this webconfig


Problem is: when i click on any of image/document/... manager to upload an image, then
it redirects the iframe containing the manager to the login page.
Before that it IIS complained that the request url is too big, which you can see i have increased.

WHY does it redirect?

I cannot reproduce this succesfully or consistently, but we are getting hundreds of reports that when users click on the radtextbox (which is in single line mode) field that they can't successfully put the cursor into the box. In some occasions, when this has happened to me, I've been able to succeed in putting the cursor into the box by clicking on the very top pixel or two of the box, but the rest of the box doesn't allow you to click into it.

Any ideas? I'm having to convert the entire site to asp:TextBox controls which suck.
