SummaryRowsBottom

Hi

I have following code for the RowFormatting event of a Gridview..

string sam = PostcountSummary();

GridViewSummaryItem Total = new GridViewSummaryItem("FullName", " Journal Entry Count: {0} ", GridAggregateFunction.Count);

GridViewSummaryItem sumDebCre = new GridViewSummaryItem("DebitAmount", " $ {0}", GridAggregateFunction.Sum);

GridViewSummaryItem sumPost = new GridViewSummaryItem("PostedImage", "{0}", sam);

GridViewSummaryRowItem summaryRowItem = new GridViewSummaryRowItem(new GridViewSummaryItem[] { Total, sumDebCre, sumPost });

if (this.SummaryDataGridView.SummaryRowsBottom.Count > 0)

{

this.SummaryDataGridView.SummaryRowsBottom.Clear();

}

this.SummaryDataGridView.SummaryRowsBottom.Add(summaryRowItem);

But After Execution(run) the Project I get Error like---
--TargetInvocationException was unhandled
Exception has been thrown by the target of an invocation.

Please Let me know, How to Solve this issue...
Thanks

DataType of Enum and display in grid

Hello,
I have a scenario, where i need some help of you guys.

In this sample application i have created 1 Enum with short datatype.
Also, Enum is flagged enum.

[Flags]

public enum MyType : short

{

None = 0,

NseFO = 1,

BseFO = 2,

NseCM = 4,

BseCM = 8,

NseCD = 16,

Use = 32,

}

Now i have created below code for generate output as shown in picture attached here.

private void Form1_Load( object sender, EventArgs e )

{

//DataColumn dt =new DataColumn("Value",typeof (Test));

//dt.DataType = typeof (Test);

//dttemp.Columns.Add(dt);

dttemp1.Columns.Add("ID",typeof(int));

dttemp1.Columns.Add( "Value", typeof( int ) );

//DataColumn dt = dttemp.Columns["Value"];

//dt.DataType = typeof (Test);

////dttemp.Columns.Add(dt);

dttemp1.Rows.Add(0, 0);

dttemp1.Rows.Add( 1, 1 );

dttemp1.Rows.Add( 2, 2 );

dttemp1.Rows.Add( 3, 3 );

dttemp1.Rows.Add( 4, 4 );

dttemp1.Rows.Add( 5, 5 );

temp2 = dttemp1.Clone();

DataColumn dcolumn = temp2.Columns["Value"];

dcolumn.DataType = typeof( ExchangeType );

DataTable dtfinal = temp2.Clone();

foreach( DataRow row in dttemp1.Rows )

{

temp2.Rows.Add( row.ItemArray );

}

DataView filter = new DataView(temp2);

dataGridView1.DataSource = filter;

c1Flex1Grid.DataSource = filter;

radGridView2.DataSource = filter;

}

There is no other event handled here for any other grids.

This simple code producing different out put as shown.

Can you tell me how can i get same output in telerikgridview??????

Adding Raditems to Ribbontab "reposted"

Hi
i couldn't find my previous post with the same title ... sorry if im reposting it .... but i did a search and didn't find it

im trying to use office 97 them form with my project .. i dont had any tools to put in the ribbons tho . im just trying to use the ribbon tabs and its tab area as a first stage of data navigation. i.e: select tab-project/select project(checkbotton or radpageview tabs) then select further categories and sort option outside the ribbonbar

projects should be added according to data entries and therefore i need to add either radpageview with tab for each project or radbutton which should act as check button
is their a way to add such raditems to ribontab? can they be docked their?.

note: i thought of using one ribbon group with button for each data entry but the buttons and the raibbongroud dont seem to be fittable inside the available area.

any thoughts will be appreciated.

thx and sorry for reposting

Theme not loaded in runtime...

Hello,

I'm creating an windows forms application (VS 2010), with a custom theme for a tabcontrol. I've created a theme with the thembuilder and in designmode, the theme is loaded correctly, but in runtime my tabcontrol is white and black, without layout.

I've added a radThemeManager and added the them (xml) as resource to my project. I've loaded the theme in my thememanager, but still it won't work.

It's just like the theme is not loaded... Are there any suggestions?

Tnx!

Simple binding to a self relating datatable

This is crazy.

A simple form, with one control, a radtreeview, opens a data table and attempts to bind it to the control.

Public Class frmTree2
    Private cmdTemp As New OracleCommand
    Private dvTemp As DataView
    Private dtTemp As New DataTable
    Private daTemp As OracleDataAdapter

    Private Sub frmTree2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        With cmdTemp
            .CommandType = CommandType.StoredProcedure
            .Connection = db.oraCn
            .CommandText = "badgernet.web_read_util.group_tree_dept"
            .Parameters.Clear()
            .Parameters.Add("out_rs", OracleDbType.RefCursor, DBNull.Value, ParameterDirection.Output)
        End With
        daTemp = New OracleDataAdapter(cmdTemp)
        dtTemp.Clear()
        daTemp.Fill(dtTemp)
        Me.RadTreeView1.DataSource = dtTemp
        Me.RadTreeView1.DisplayMember = "group_name"
        Me.RadTreeView1.ParentIDMember = "p_id"
        Me.RadTreeView1.DataMember = "g_id"
        Me.RadTreeView1.ValueMember = "id"
    End Sub
End Class

That's the whole form.

Table contents
id     g_id  p_id   group_name

500    10    -1     Athletic Dept
780    780    10    May, Keith
141    141    10    Chelesvig, Bart
142    142    10    Clark, Christopher

It will display the name field, but no hierarchy - if I comment out the valuemember line. If I leave that in there I get an "InvalidCastException" - Unable to cast object of type 'System.Windows.Forms.RelatedPropertyManager' to type 'System.Windows.Forms.CurrencyManager'.

I took this code right out of your (so-called) documentation, but it doesn't even come close to working. Any help would be greatly appreciated.

[Solved] Possible Bug - Multilanguage RTL and LTR

It seems that there is a bug in the Telerik Grid Control.

I have a database that contains a
1 - numerical field - integer
2 - memo field - contents of the field are in Arabic
3 - memo field - contents of the field are in English

I set up the grid with all columns displayed

When RTL is set to True
The grid displays with the Arabic correctly displayed, but the English is incorrectly displayed. Scrollbar appears on the Left.

When RTL is set to False
The grid displayed with the English correctly displayed, but the Arabic incorrectly displayed. Scrollbar appears on the Right.

It is not a choice for me to display either the English only or the Arabic only - I need to display both at the same time. Does anybody have any possible solution?

I would also like the ability to choose the side I would like to place my scrollbar - on the left of the grid or the right.

This is a realworld situation and desperately need some help.
Are there any alternative products that would help achieve this?

Many thanks

GridView
