TriState and

Hello,

I use a treeview include tristate mode.
My problem is that:

When i get the checkeble nodes with the following js function,
var nodes = treeview.get_checkedNodes();
I get also the parent node that its state is indeterminate.

[¦] Parent
    [X] Child 1
    [X] Child 2
    [  ] Child 3

Is there any way to get only the checkeble nodes with no indeterminate state?

Thanks,
Oren

RadMaskedTextBox behavior

Hello,

I am using the RadMaskedTextBox to display a mask for a Social Security Number field, but I would like to display the mask only when the textbox has the focus. When the textbox has the focus the mask should be displayed, such as ___-__-____. If the user enters a number of values, the mask should still be displayed along with the values entered such as 415-74-____. If the user does not enter any values or deletes these values, the mask should not be displayed. Is this possible using the RadMaskedTextBox?

This brings a couple of issues to mind:

1. When the mask is constantly displayed in a field that is not required or doesn't need to be validated, the RadMaskedTextBox will send the mask characters to the database field. The developer then needs to code for the mask as in:

if

(SSN == "___-__-____")
SSN = string.Empty;

I don't feel as though this is proper. Is there a way around this? Can the mask be displayed only when values exists?

Hi,

I am using adhoc tool to populate data for RadChart pie and I don't know the column name at front for DataYColumn until end user run the adhoc query. I did add DataYColumn at run time using following code:



radChart.Series[0].DataYColumn = ds.Tables[0].Columns[1].ColumnName;
radChart.PlotArea.XAxis.DataLabelsColumn = ds.Tables[0].Columns[0].ColumnName;
radChart.ChartTitle.TextBlock.Text = ChartTitle;
radChart.Series[0].Name = SeriesName;




protected void radChart_ItemDataBound(object sender, Telerik.Charting.ChartItemDataBoundEventArgs e) {
        DataSet ds = (DataSet)ViewState["Result"];
        e.SeriesItem.Name = ((DataRowView)e.DataItem)[ds.Tables[0].Columns[0].ColumnName].ToString();
 
        e.SeriesItem.ActiveRegion.Tooltip += ((DataRowView)e.DataItem)[ds.Tables[0].Columns[0].ColumnName].ToString() + ":  " + e.SeriesItem.YValue;
    }





and aspx looks like following:


<telerik:RadChart ID="radChart" runat="server" Height="650px" AutoLayout="true" OnItemDataBound="radChart_ItemDataBound"
                                  SkinsOverrideStyles="True"> 
                                  <;                                                                  
                                  <ChartTitle>
                                    <TextBlock>
                                    </TextBlock>
                                  </ChartTitle>
                                  <Series>
                                    <telerik:ChartSeries>
                                      <Appearance LegendDisplayMode="ItemLabels" TextAppearance-AutoTextWrap="True">
                                      </Appearance>
                                    </telerik:ChartSeries>
                                  </Series>
                                  <PlotArea>
                                    <XAxis AutoScale="true">
                                      <Appearance TextAppearance-TextProperties-Color="Black">
                                        <TextAppearance AutoTextWrap="true">
                                        </TextAppearance>
                                        <LabelAppearance Position-AlignedPosition="Left" RotationAngle="45">
                                        </LabelAppearance>
                                      </Appearance>
                                    </XAxis>
                                  </PlotArea>
                                </telerik:RadChart>

For some reason, the Pie legend won't show up on the side.



Please help me
