[Solved] ELI5 code blocks from RadGrid and RadSearchBox

I need help understanding a couple of code blocks got from the demo but it works

1) got this code from the demo. It works. I just don't understand how it works. What does the Dictionary does (ELI5)

protected void RadSearchBox1_Search(object sender, SearchBoxEventArgs e)

{

RadSearchBox searchBox = (RadSearchBox)sender;

string JobOrderNumber = string.Empty;

string likeCondition;

if (e.DataItem != null)

{

JobOrderNumber = ((Dictionary<string, object>)e.DataItem)["JobOrderNumber"].ToString();

if (!string.IsNullOrEmpty(JobOrderNumber))

{

likeCondition = string.Format("'{0}{1}%'", searchBox.Filter == SearchBoxFilter.Contains ? "%" : "", ((Dictionary<string, object>)e.DataItem)["JobOrderNumber"].ToString());

SqlDataSource1.SelectCommand = "SELECT [JobOrderIndex], [JobOrderNumber], [JobOrderDate], [JobOrderStatus], [ProfitCenter], [JobType]" + "FROM[Bak-JobOrder] WHERE [" + searchBox.DataValueField + "] LIKE " + likeCondition;

RadGrid1.DataBind();

}

2) I added a scenario using the UI in visual studio. I Master/Detail scenario which is similar to this demo.

What does this code do?

protected void Page_PreRender(object sender, EventArgs e)

{

if (RadGrid1.SelectedIndexes.Count == 0)

RadGrid1.SelectedIndexes.Add(0);

if (RadGrid2.SelectedIndexes.Count == 0)

{

RadGrid2.Rebind();

RadGrid2.SelectedIndexes.Add(0);

}

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

RadGrid2.SelectedIndexes.Clear();

}

Points plotted in wrong locations

So,I have an HtmlChart that I'm using for some graphs a client of mine needs. I've managed to get everything done up just so, but I noticed when I looked at the tooltip for the points,that the points appear to be plotted in the wrong location. (See image)

I've double-checked that the tooltip is showing the correct values for the points. But as you can see in the image, the points are off.

Any help with this is greatly appreciated.

Accessing tabstrip from different page

Hi,

I am using a web application, which does not have a master page. I have a header.ascx page, in which I have declared TabStrip. The tabstrip is displaying fine, but on selecting a page, the tab header color is not getting changed and also not showing sub tabs.

I used the below code:

Header.ascx:

<telerik:RadTabStrip ID="MyTab1" CausesValidation="false" SelectedIndex="0" runat="server"

Skin="Forest" EnableEmbeddedSkins="false" >

<Tabs>

<telerik:RadTab runat="server" Text="Home" NavigateUrl="~/abc.aspx">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

In abc.aspx, I have referenced the header.ascx page, and I am trying to use the radtab as below in cs code:

RadTabStrip menuStrip = (RadTabStrip).FindControl("RadTab");

menuStrip.FindTabByValue("abc").Selected = true;

How to refer the tab strip in subsequent pages?

Thanks

[Solved] GridNumericColumn with Decimal Digits when Edit

Guys,

How can I set decimal digits to a GridNumericColumn when inserting/editing a record (NumericTextBox)?
I alredy have set the DataFormatString = "{0:C2}", but the grid ignores the format when edit mode.

    
            <telerik:GridNumericColumn NumericType="Currency"  DataField="Valor" DataType="System.Decimal" HeaderText="Valor" SortExpression="Valor" UniqueName="Valor" DataFormatString="{0:C2}">  
        
                <ItemStyle HorizontalAlign="Right"></ItemStyle> 
        
            </telerik:GridNumericColumn>

Add a filter programatically before export

I need to export my already filtered data grid, but my requirement says that inactive records should not be exported, so i'm trying to do this :

01. grdCct.ExportSettings.IgnorePaging = true;

02. grdCct.ExportSettings.ExportOnlyData = true;

03. grdCct.ExportSettings.Csv.FileExtension = "csv";

04. grdCct.ExportSettings.FileName = "Export_" + DateTime.Now.ToShortDateString();

05.// Column 6 is my "Active" column as text "Y/N"

06. grdCct.Columns[6].CurrentFilterValue="Y";

07. grdCct.MasterTableView.Rebind();

08.

09. grdCct.MasterTableView.ExportToCSV();

Can anybody tell me the correct way to accomplish this?.

Impossible to type into my SearchBox

Hi, i have a problem with a RadSearchBox in IE11.

My SearchBox works when i launch the page for the first time, but in my page i use a modal window, wich is simply a Div. When this modal window is open, i put the Div which contains the SearchBox (and other elements) in "visibility: hidden;".

And when i close my modal window, i put it back to "visibility: visible", and from that moment it is impossible to write in the SearchBox.

I tried to add javascript to solve the problem, but nothing worked. Does someone have an idea?

1.var input = $j("#<%=SearchBox.ClientID%> input[type=text]");

2.input.focus(function () {

3. this.value = "";

4. this.contenteditable = true;

5.})

RadGrid isn't responsive from Theme Builder

Hello and thank you in advance,

I have created a customized theme using the Telerik Theme Builder which is supposed to be compatible with Bootstrap from what I understand. However, the issue I'm seeing is that the grid does not resize responsively when I reduce the size of the browser window. Below is the markup for my grid. The grid still appears to take up the size of the screen that you would see if you viewed it from a laptop but does not resize to fit a mobile-device-sized window.

<asp:Content ID="Content1" ContentPlaceHolderID="mainContent" runat="Server">

<asp:Panel ID="borderPanel1" runat="server" Style="margin-left: 2px;">

Binding a referenced member to RadGrid while using EntityDataSource control

Hi,

I got stuck in an issue while trying to bind a reference member (navigation property - foreign key reference) to a dropdownlist. I have Telerik RadGrid control which gets the data using a EntityDataSource control. Here is the model description:

    
            Applications: AppId, AppName, ServerId 
        
            Servers: ServerId, ServerName

The Applicaitons.ServerId is a foreign key reference to Servers.ServerId. The RadGrid lists the applications and allows the user to insert/update/delete an application. I want to show the server names as a dropdownlist in edit mode which I'm not able to. . Here is my aspx code:

    
            <telerik:RadGrid ID="gridApplications" runat="server" Skin="Sunset"

                    </EditFormSettings> 
        
                </MasterTableView> 
        
            </telerik:RadGrid> 
        
            <asp:EntityDataSource ID="applicationsEntityDataSource" runat="server"  
        
                ConnectionString="name=AnalyticsEntities" EnableDelete="True"  
        
                EntityTypeFilter="Applications" EnableInsert="True" EnableUpdate="True" EntitySetName="Applications"  
        
                DefaultContainerName="AnalyticsEntities" Include="Servers"> 
        
            </asp:EntityDataSource>

I tried another approach where I replaced the GridTemplateColumn with the following code

    
            <telerik:RadComboBox ID="RadComboBox1" DataSourceID="serversEntityDataSource" DataTextField="ServerName" DataValueField="ServerId" AppendDataBoundItems="true" runat="server" > 
        
            <Items> 
        
                <telerik:RadComboBoxItem /> 
        
            </Items>

and using a separate EntityDataSource control as follows:

    
             <asp:EntityDataSource ID="serversEntityDataSource" runat="server"  
        
                ConnectionString="name=AnalyticsEntities" EnableDelete="True"  
        
                EntityTypeFilter="Servers" EnableInsert="True" EnableUpdate="True" EntitySetName="Servers"  
        
                DefaultContainerName="AnalyticsEntities"> 
        
            </asp:EntityDataSource>

I'm able to populate the dropdownlistbox, but I get the following error, when I try to insert a new record.

    
            Application cannot be inserted. Reason: Entities in 'AnalyticsEntities.Applications' participate in the 'FK_Servers_Applications' relationship. 0 related 'Servers' were found. 1 'Servers' is expected.

My question is, how do you bind the navigation property and load the values in the DropDownList/RadComboBox control? Do I need two separate EntityDataSource control or just one control is enough?

I use the Telerik RadControls for ASP.NET AJAX Q3 2009 SP2. The environment is as follows:
Windows XP SP3, Visual Studio 2008/.NET Framework 3.5, Visual C#.
