issue with Ajax and dynamic controls

Hi,

I'm creating a control dynamically with a lot of child controls (ex dropdownlists).

    
            DropDownListControl ddlControl = (DropDownListControl)this.LoadControl("FormControls/DropDownListControl.ascx");  
        
            ddlControl.ID = "ddlControl_" + groupTable.Rows.Count + "_" + columnIndex;  
        
            RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(this, ddlControl);

With that last sentence I thougth the update the dynamic created dropdownlists if the parent usercontrol (this) was changed.

When I run this code and change the parent usercontrol he gives me the following exception:
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ddlControl_1_0Panel'. If it is being updated dynamically then it must be inside another UpdatePanel.

Can anyone tell me how I have to solve this without losing the creation of the dynamic child controls?

Thanks
Bert

ListBox Remove Items

Can someone post how to remove all items from a RadListBox? This below code in the cs file doesn't work.

foreach (RadListBoxItem item in RadListBox1.Items)

{

item.Remove();

//RadListBox1.Items.Remove(item);

}

My (hopefully temporary) workaround for this is that I create an empty DataSet and rebind that to the RadListBox.

Calling Javascript After RowDrop

We're using the Grid_RowDrop EventHandler to perform a few operations after a row is dropped from one grid to another. The only issue we've run into is that we need to dynamically change some text outside of the two grids after the drop occurs. One possible way to do this would be with some Javascript, but while it's easy to call Javascript before the drop finishes with OnRowDropping and OnRowDropped, I can't find a way to call Javascript after the Grid_RowDrop EventHandler completes. If there's a way to do this, it would be great to know.

On the other hand, if it's better to update this text from within the Grid_RowDrop EventHandler itself by putting the text in a control (RadAjaxPanel maybe?), that would work too. We'd appreciate some advice either way on the best solution to this problem. Thanks.

configure XAxis.LabelStep at runtime

Hello,

I have a chart that display a series of data across a date range. There are 24 data points per day. Sometimes we are displaying 30 days, sometimes we are displaying many more days. Obviously this is to many labels to display. I would liket there to always be about 30 labels no matter how many days worth of data I am sidplaying. I understand the only way to do this is by using the LabelStep property. I would like to set the label step property at runtime based on the number of data points that are in the chart.

I add the labels through the PlotArea.XAxis.AddRange method. The series is bound to the SQL datasource. In the chart_ItemDataBound event I get the number of datapoints and try to set the LabelStep property as shown below. However, no matter what I try the labelstep property that I set at runtime is not used and rather is uses the value set as designtime.

private void chart_ItemDataBound(object sender, EventArgs e)

{

//get handles

Telerik.Reporting.Processing.Chart ProcessingChart = (Telerik.Reporting.Processing.Chart)sender;

Telerik.Reporting.Chart ChartDefinition = (Telerik.Reporting.Chart)ProcessingChart.ItemDefinition;

//get the number of datapoints

int iDataPoints = ChartDefinition.Series[0].Items.Count;

if (iDataPoints > 0)

{

//setting the labelstep on chart defination object from the processing chart

ChartDefinition.PlotArea.XAxis.LabelStep = iDataPoints / 30;

//also have tried setting setting the labelstep on actual chart object

chart.PlotArea.XAxis.LabelStep = iDataPoints / 30;

}

Why is the chart not using the labelstep property that I set at runtime?

Thanks,

Chris

Aggregate Calculated From Other Aggregates

I searched but couldn't find an answer, so I'm hoping someone can point me in the right direction.

If I have a grid with 5 columns:

Client Name
Fees 1
Fees 2
Discount
Percentage

Discount is the difference between Fees1 and Fees2 (Fees1 - Fees2). Percentage is Fees1/Fees2. The grid has aggregates for the Fees 1 column, Fees 2 column, and Discount column (these are all Sums). Doing a Sum or Average on the Percentage column will not give me the right number...what I need to do is take the Sum(Fees1)/Sum(Fees2) to get the Average Percentage...

So, is there a way to show an aggregate value for a column (the Average Percentage) that is calculated from the aggregates of other columns?

Thanks
Tye
