Hello,

can you help me find resolve my following problem..?

I have RadGrid with Numeric Columns and one GridButtonColumn for automatic deletes. This is markup of one of my columns:

<telerik:GridNumericColumn DataField="HoursAmount" HeaderText="hrs." DataFormatString="{0:### ##0.0}"

ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" />

When I click on delete link on column where value is bigger then 1000, grid write this error: Failed to set one or more properties on type Arcon.Web.ServiceJobHour. 1 000,00 is not a valid value for Decimal.

Now I'm finding way to use DecimalDigits property of GridNumericColumn but this doesn't do anything...

<telerik:GridNumericColumn DataField="HoursAmount" HeaderText="hrs." DataFormatString="{0:### ##0.0}"

ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" DecimalDigits="2" />

Can you help me find to resolve it?

Thanks

DataFormatString.zip

Hello Daniel,

I am attaching a simple test page which works with the DataFormatString you have specified. Let me know what is different in your application.

Hello Pavel,

important different between our projects is I'm using LinqDataSource. Date type of my problematic column in DB is Money and in LINQ Data Model is Decimal. Please try connect your radgrid to DB via LINQ and probably you will see same error...

What is DecimalDigits property on GridNumericColumn? I edited your sample for show you why I think about this function. Please look at this...

{

RadGrid1.DataSource = SampleData;

}

public DataTable SampleData

{

get

{

if (Session["_data"] == null || !Page.IsPostBack)

{

DataTable table = new DataTable();

table.Columns.Add("ID", Type.GetType("System.Int32"));

table.Columns.Add("Value1", Type.GetType("System.Double"));

table.Columns.Add("Value2", Type.GetType("System.Double"));

table.Columns.Add("Value3", Type.GetType("System.Double"));

Random rand = new Random();

for (int i = 0; i < 10; i++)

{

table.Rows.Add(i,

rand.Next(0, 50),

i * 12 * 100.1234);

}

Session["_data"] = table;

}

DataTable original = (DataTable)Session["_data"];

DataTable ret = original.Clone();

DataRow[] sortedRows = original.Select("", "ID ASC");

foreach (DataRow row in sortedRows)

{

ret.Rows.Add(row.ItemArray);

}

return ret;

}

Hi Daniel,

I cannot reproduce the problem when binding the Grid to a LinqDataSource as well. As for the DecimalDigits property of the column, it determines the formatting in the input textbox which is generated for this cell, when the item is put in edit mode. It does not affect the formatting of the data in the cell in regular view mode.

let me know if any concern.

Hello Jayesh,

please try to run folowing code and tell how many decimal digits do you see in second columns where in code is set only one decimal digit:

<%@ Page Language="C#" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<%@ Import Namespace="System.Data" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

protected void RadGrid1_NeedDataSource(object sender, EventArgs e)

{

RadGrid1.DataSource = SampleData;

}

public DataTable SampleData

{

get

{

if (Session["_data"] == null || !Page.IsPostBack)

{

DataTable table = new DataTable();

table.Columns.Add("ID", Type.GetType("System.Int32"));

table.Columns.Add("Value1", Type.GetType("System.Double"));

table.Columns.Add("Value2", Type.GetType("System.Double"));

table.Columns.Add("Value3", Type.GetType("System.Double"));

Random rand = new Random();

for (int i = 0; i < 10; i++)

{

table.Rows.Add(i,

rand.Next(0, 50),

i * 12 * 100.123);

}

Session["_data"] = table;

}

DataTable original = (DataTable)Session["_data"];

DataTable ret = original.Clone();

DataRow[] sortedRows = original.Select("", "ID ASC");

foreach (DataRow row in sortedRows)

{

ret.Rows.Add(row.ItemArray);

}

return ret;

}

</script>

<MasterTableView DataKeyNames="ID" Width="200px">

<Columns>

<telerik:GridNumericColumn DataField="Value3" HeaderText="hrs." DataFormatString="{0:### ##0.00}" />

In edit mode, GridNumericColumn does not get RadNumericTextBox as its control. It gets only TextBox control.
For example, here when the grid line is in edit mode, I want to get the RadNumericTextBox of the GridNumericColumn "salary_person".
But I am getting only TextBox control and I am not able to set my groupseparator.

protected void IGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
{
        GridEditableItem editItem = (GridEditableItem)e.Item;
         RadNumericTextBox txtNum = (RadNumericTextBox)editItem[salary_person].Controls[0];
        txtNum.NumberFormat.GroupSeparator = "*";
}
}

Any ideas?

Hi Kavitha,

GridNumericColumn in edit mode, it displays a RadNumericTextBox control. This column type is for numeric values. Please check the sample code snippet I tried.

ASPX:

<telerik:GridNumericColumn DataField="Freight" HeaderText="GridNumericColumn" UniqueName="Freight">

</telerik:GridNumericColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))

{

GridEditableItem editItem = (GridEditableItem)e.Item;

RadNumericTextBox NumericTextBox = (RadNumericTextBox)editItem["Freight"].Controls[0];

NumericTextBox.NumberFormat.GroupSeparator = "*";

}

Please provide the code if it doesn't help.

Thanks,
Shinu.

Hi Kavitha,

When the grid is in view mode, the GridNumericColumn renders a literal control. To format the data rendered in this case, you can try using the DataFormatString property. I tried with accessing the cell and replacing the ',' with '*'. Here is the sample code snippet.

ASPX:

<telerik:GridNumericColumn DataField="Freight" HeaderText="GridNumericColumn" UniqueName="Freight" DataFormatString="{0:N}"></telerik:GridNumericColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem ditem = (GridDataItem)e.Item;

string value = ditem["Freight"].Text;

if (value.Contains(","))

{

value = value.Replace(",", "*");

}

ditem["Freight"].Text = value;

}

Thanks,
Shinu.
